  A nosebleed is loss of blood from the tissue lining the nose. Bleeding most often occurs from one nostril only. […] Nosebleeds are very common. Most nosebleeds occur because of minor irritations of the inside of the nostrils or colds. […] The nose contains many small blood vessels that bleed easily. Air moving through the nose can dry and irritate the membranes lining the inside of the nose. Crusts can form that bleed when irritated. Nosebleeds occur more often in the winter, when cold viruses are common and indoor air tends to be drier. […] Most nosebleeds occur on the front of the nasal septum. This is the piece of the tissue that separates the two sides of the nose. This type of nosebleed can be easy for a trained professional to stop. Less commonly, nosebleeds may occur higher on the septum or deeper in the nose such as in the sinuses or the base of the skull. Such nosebleeds may be harder to control. However, nosebleeds are rarely life threatening.

  Epistaxis, or a nosebleed, is when you lose blood from the tissue that lines the inside of your nose. Dry air causes nosebleeds. […] Nosebleeds have many causes, including dry air, allergies and recreational drug use. […] The most common cause of nosebleeds is dry air. […] You may also develop a nosebleed if you: Insert an object in your nose, Injure your nose and/or face, Have a deviated septum, Have an upper respiratory infection or sinus infection that makes you keep sneezing, coughing and blowing your nose, Have allergic or nonallergic rhinitis (inflammation of your nasal lining), Frequently use antihistamine or decongestant nasal sprays, which can dry out your nasal membranes, Take blood-thinning medications like aspirin, NSAIDs or warfarin, Breathe in chemicals from cleaning supplies, fumes at your workplace or other strong odors, Use recreational drugs (like cocaine) that you inhale through your nose.

  Low humidity may lead to mucosal irritation. Epistaxis is more prevalent in dry climates and during cold weather due to the dehumidification of the nasal mucosa by home heating systems. […] Topical nasal drugs such as antihistamines and corticosteroids may cause mucosal irritation. Especially when applied directly to the nasal septum instead of the lateral walls, they may cause mild epistaxis. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) are also frequently involved. […] Septal deviations (deviated nasal septum) and spurs may disrupt the normal nasal airflow, leading to dryness and epistaxis. The bleeding sites are usually located anterior to the spurs in most patients. The edges of septal perforations frequently harbor crusting and are common sources of epistaxis.

  Nosebleeds are one of the most common healthcare problems. Medically, it is called Epistaxis. They are usually a result of the rupture of tiny blood vessels in the anterior or posterior part of the nose. […] The instances of elderly people suffering from posterior nose bleeding are usually higher than children or adults. Nosebleeds in the elderly can be because of something more severe like heart disease or hypertension. […] Here are a few common causes of nose bleeding: Roughly blowing your nose, Picking your nose, A respiratory tract infection, Major sinus issue, Blunt trauma (like accidents), Environmental irritants, Severe allergies (including food allergies), Dryness in the nose, A blocked nose, High blood pressure, Deviated septum (abnormal shape of the wall that separates two sides of the nose), Alcoholism, Blood-thinning drugs (aspirin, warfarin, non-steroidal anti-inflammatory drugs and others), Chemical irritants (chemical fumes at workplace, chemicals in cleaning supplies, other strong odors), High altitudes air is drier and thinner (lack of oxygen) as the altitude increases, Allergic and Non-allergic rhinitis (inflammation of the nasal lining), Cocaine and other drugs inhaled through nose, Frequent use of nasal sprays and drugs to treat stuffy, runny, or itchy nose.

  https://www.drugs.com/health-guide/nosebleed-epistaxis.html

  The inside of the nose is covered with moist, delicate tissue (mucosa) that has a rich supply of blood vessels near the surface. […] Certain people are more likely to get nosebleeds because of their environment, work history, health problems or use of medications that increase the tendency to bleed. Common risk factors for nosebleeds include: […] A hot, dry indoor climate – This is a trigger for nosebleeds in parts of the United States where heat (especially forced hot air) is used during the winter. […] A deviated septum – If the wall between the two nostrils is shifted to one side (deviated), air flow in the nostrils is uneven. […] Colds and allergies – Upper respiratory tract infections and allergies cause inflammation in the nose, which can increase the risk of bleeding. […] Exposure to irritating chemicals – The primary culprit is cigarette smoke, even secondhand cigarette smoke.

  Epistaxis, or nosebleed, is one of the most frequent ear, nose, and throat emergencies encountered in both primary care and emergency settings. […] Anterior nosebleeds typically arise from Kiesselbach’s plexus, located on the anterior nasal septum. […] There are multiple causes of epistaxis, which can be divided into local, systemic, environmental, and medication-induced. […] Local causes of epistaxis include: Digital manipulation, Deviated septum, Trauma, Chronic nasal cannula use. […] Systemic causes of epistaxis include: Alcoholism, Hypertension, Vascular malformations, Coagulopathies (von Willebrand disease, hemophilia). […] Environmental factors in epistaxis include: Allergies, Environmental dryness (more common in winter months). […] Medications that can cause epistaxis include: Nonsteroidal anti-inflammatories (NSAIDs; ibuprofen, naproxen, aspirin), Anticoagulants (warfarin), Platelet aggregation inhibitors (clopidogrel), Topical nasal steroid sprays, Supplements or alternative medications (vitamin E, ginkgo, ginseng), Illicit drugs (cocaine). […] While epistaxis is a widespread spontaneous problem, rarer etiologies such as neoplasms or vascular malformations must always be in the differential diagnosis, particularly if additional symptoms such as unilateral nasal obstruction, pain, or other cranial nerve deficits are noted.

  Nosebleed can be caused by: Irritation due to allergies, colds, sneezing or sinus problems, Very cold or dry air, Blowing the nose very hard, or picking the nose, Injury to nose, including a broken nose, or an object stuck in the nose, Sinus or pituitary surgery (transsphenoidal), Deviated septum (tissue that divides the nose into 2 nostrils), Chemical irritants including medicines or drugs that are sprayed or snorted, Overuse of decongestant nasal sprays, Oxygen treatment through nasal cannulas, Snorting cocaine or amphetamine. […] Repeated nosebleeds may be a symptom of another disease such as high blood pressure, a bleeding disorder, or a tumor of the nose or sinuses. Blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin, may cause or worsen nosebleeds.

• #1 Nosebleed Causes and Treatments – familydoctor.org

  https://familydoctor.org/condition/nosebleeds/

  A nosebleed is blood loss from the tissue that lines your nose. It can affect both nostrils, but most often occurs in only one nostril. Usually, a nosebleed is not serious. […] Sometimes, though, nosebleeds are more serious. These stem from large vessels in the back of the nose. Nosebleeds from these larger vessels often occur after an injury, in young children, or in the elderly. Usually, the older the patient, the more serious the nosebleed. […] Two of the most common causes of nosebleeds are dryness (often caused by indoor heat in the winter) and nose picking. These 2 things work together — nose picking occurs more often when mucus in the nose is dry and crusty. Colds also can cause nosebleeds. […] Less common causes include injuries, allergies, or the use of illegal drugs, such as cocaine. Children may stick small objects up their noses, and that can cause the nose to bleed. Older people may have atherosclerosis (which is the hardening of the arteries), infections, high blood pressure, or blood clotting disorders that may cause nosebleeds.

  https://www.emedicinehealth.com/nosebleeds/article_em.htm

  Nosebleeds (epistaxis, nose bleed, nosebleed) can be dramatic and frightening. Fortunately, most nosebleeds are not serious and usually can be managed at home, although sometimes medical intervention may be necessary. […] Most nosebleeds do not have an easily identifiable cause. However, trauma to the nose is a very common cause of nosebleeds. Nosebleeds can be caused by trauma to the outside of the nose from a blow to the face, or trauma to the inside of the nose from nose picking. Other conditions that predispose a person to nosebleeds include: exposure to warm, dry air for prolonged periods of time, nasal and sinus infections, allergic rhinitis, nasal foreign body (object stuck in the nose), vigorous nose blowing, nasal surgery, deviated or perforated nasal septum, and cocaine use. […] Less commonly, an underlying disease process or taking certain medications may cause a nosebleed or make it more difficult to control. Inability of the blood to clot is most often due to blood-thinning medications such as warfarin (Coumadin), clopidogrel bisulfate (Plavix), nonsteroidal anti-inflammatory drugs (NSAIDs), or aspirin.

  A bloody nose from the common cold, sinus infection or COVID is normal. All create congestion and the dilation of blood vessels, which can cause a bloody nose or bloody mucus. […] Women experience fluid shifts when they become pregnant and blood vessels dilate even in the nose. It makes pregnant women more prone to nosebleeds, Dr. Luft says. […] Stress can cause bloody noses. Dr. Luft says this is primarily through an increase in blood pressure. When stress raises your blood pressure, your blood vessels are more fragile and prone to bleeding, including nosebleeds, Dr. Luft says. […] Low platelets (tiny blood cells that help your blood clot), a bleeding disorder or liver problems that prohibit blood clotting all put people more at risk for nosebleeds. […] If your nosebleeds happen frequently, then allergies, the underlying conditions mentioned above or other health problems are likely to blame.

• #1 What Causes Nosebleeds? – ENT Clinics San Antonio

  https://www.texasent.com/blog/nosebleeds-ent/

  Nosebleeds happen to most of us at some point during our lifetime. […] The blood vessels within our nose are very delicate, which means that they are prone to bursting and causing nosebleeds. Therefore, the two most common causes of nosebleeds are nose picking and dry air. Dry air can dry out the nasal passages, which leaves the area prone to infection and cracking. […] Other causes include: Repeated nose blowing, Allergies, Broken nose, Acute or chronic sinusitis (a sinus infection), Common cold, Irritants, Certain allergy medications (these medications can dry out the nose), Traumatic injury to the nose, Deviated septum, Bleeding disorders, High altitude, Excessive use of blood thinners or anti-inflammatory medications. […] While rare, it is possible for a posterior nosebleed to be a sign of high blood pressure or a blood disorder (e.g. hemophilia).

  Nosebleeds, also called epistaxis (ep-ih-STAK-sis), are common. They happen when the tender blood vessels in the nose break. Common nosebleed causes can include changes of season, dryness, scratching, some medicines and injuries. People on blood thinners may have worse nosebleeds than do others. […] You have nosebleeds often. You may need to have a blood vessel cauterized. Cautery is a method that burns and seals blood vessels using electric current, silver nitrate or a laser. Also, a care provider might pack the nose with special gauze or an inflatable latex balloon. Both packing methods put pressure on the blood vessel and stop the bleeding.

  https://kidshealth.org/en/teens/nosebleeds.html

  Nosebleeds are usually harmless and easily controlled, but they can look scary. […] The most common cause of anterior nosebleeds is dry air. A dry climate or heated indoor air irritates and dries out nasal membranes, causing crusts that may itch and then bleed when scratched or picked. Colds may also irritate the lining of the nose. Bleeding may happen after repeated nose-blowing. When you combine a cold with dry winter air, you have the perfect formula for nosebleeds. […] Allergies can also cause problems, and a doctor may prescribe medicine such as antihistamines or decongestants to control an itchy, runny, or stuffy nose. The medicine can also dry out the nasal membranes and contribute to nosebleeds. […] An injury to the nose may cause bleeding and isn’t usually cause for alarm. […] Nosebleeds are rarely cause for alarm, but frequent nosebleeds might indicate a more serious problem. If you get nosebleeds more than once a week, you should see your doctor.

  Common Nosebleeds: Nosebleeds (epistaxis) are rarely life threatening, and yet they can cause a fair amount of distress. […] The blood vessels inside the nose are protected by only a thin and delicate mucosal membrane, and any trauma or source of irritation may result in rupture of vessels and bleeding. […] There are two types of nosebleeds: anterior (90 to 95% of cases, generally arising from vessels on the nasal septum just inside the nostrils, and more common in children), and posterior (arising from vessels in the back of the nose, often more severe). […] The following are risk factors for nosebleeds: Chronic inflammation of the nose and sinuses (chronic rhinosinusitis), Improper use of nasal steroid sprays (can cause drying and crusting if sprayed directly onto the septum), Frequent or aggressive nose blowing, Severe septal deviations which cause turbulent airflow on the deviated side which results in drying and crusting and sometimes bleeding of the nasal mucosa, Cold, dry climate (central heating and air conditioning dries out the air and the nasal mucosa), Trauma (nose picking, nasal fractures, recent sinus surgery, etc.), Bleeding disorders (including the use of blood thinning medications aspirin, plavix, warfarin, etc.), Alternative medicines that may increase risk include Ginseng, Ginkgo, and Garlic, Alcoholism with associated liver disease (impairs platelet function), Kidney disease (also impairs platelet function), Thrombocytopenia (low platelet count) can result from chemotherapy, blood disorders, or autoimmune conditions, Hereditary Hemorrhagic Telangiectasia (HHT) syndrome that causes frequent nosebleeds, often severe, and runs in families, Nasal tumors tend to cause one-sided nasal obstruction and frequent nosebleeds. […] Studies have shown that high blood pressure is not a direct cause of nosebleeds; however, it does make nosebleeds more severe and more difficult to control.

  Acquired coagulopathies can be primary (due to the diseases) or secondary (due to their treatments). Among the more common acquired coagulopathies are thrombocytopenia and liver disease with its consequential reduction in coagulation factors. […] Arteriosclerotic vascular disease is considered a reason for the higher prevalence of epistaxis in elderly individuals. […] Hereditary hemorrhagic telangiectasia (HHT; also known as Osler-Weber-Rendu syndrome) is an autosomal dominant disease associated with recurrent bleeding from vascular anomalies. […] The relationship between hypertension and epistaxis is often misunderstood. Patients with epistaxis commonly present with an elevated blood pressure. Epistaxis is more common in hypertensive patients, perhaps owing to vascular fragility from long-standing disease.

• #1 Epistaxis: A Common Problem

  https://pmc.ncbi.nlm.nih.gov/articles/PMC3096213/

  The most common inherited bleeding disorders associated with epistaxis are hemophilia A, hemophilia B, and von Willebrand disease. Hemophilia A and B are caused by deficiencies in factor VIII and factor IX, respectively; both are integral components in the coagulation cascade. von Willebrand disease is caused by a qualitative or quantitative deficiency in the von Willebrand factor, a glycoprotein essential to the proper function of factor VIII. […] […] Vascular and cardiovascular diseases such as congestive heart failure, arteriosclerosis, and collagen abnormalities can also be contributing factors to epistaxis. A well-known association between hereditary hemorrhagic telangiectasia and epistaxis has been determined. Hereditary hemorrhagic telangiectasia, or Osler-Rendu-Weber disease, has an autosomally dominant inheritance pattern with incomplete penetrance. Its presenting symptom is usually epistaxis secondary to telangiectasias of the nasal mucosa.

  Liver disease, chronic alcohol abuse, kidney disease, platelet disorders, and inherited blood clotting disorders can also interfere with blood clotting and predispose to nosebleeds. […] Vascular malformations in the nose and nasal tumors are rare causes of nosebleeds. High blood pressure may contribute to bleeding, but is rarely the sole reason for a nosebleed. It is often the anxiety associated with the nosebleed that leads to the elevation in blood pressure. […] The most common cause of nosebleeds in children is from minor trauma, typically from nose picking. Other common causes of nosebleeds in a child include: Direct trauma to the nose, Upper respiratory infections, Foreign body in the nose, Allergic rhinitis, Exposure to warm, dry air, Nasal medications (for example, corticosteroids).

  Epistaxis can be divided into local and systemic etiologies. Furthermore, the most common causes of epistaxis will change as the patient ages. One constant among etiologies, though, is that epistaxis increases in frequency during winter months. The decreased humidity along with decreased temperature inhibits nasal humidification. The nasal mucosa is subject to poor local wound healing and is therefore more susceptible to bleeding. […] […] The most common local causes of epistaxis are trauma, anatomic deformities, inflammatory reactions, and intranasal tumors. […] […] The most common systemic causes of epistaxis are hypertension, aberrations in clotting ability, inherited bleeding diatheses, and vascular/cardiovascular diseases. […] […] Although the mechanistic relationship of hypertension and epistaxis is still being debated, the 2 are undeniably associated.

  Nosebleeds can also be caused by bleeding disorders, but its rare. If your nosebleed doesnt stop, or you have a lot of bleeding from your gums or when you get minor cuts, see a doctor. Bleeding disorders can be serious because platelets in your blood that help it clot are missing or arent working. […] Another rare cause of nosebleeds can be a tumor in the nose or sinuses. It may be noncancerous, also called benign, or cancerous. Only about 2,000 cases of cancerous tumors in the nose or sinuses are diagnosed in the U.S. each year. […] In some cases, nosebleeds can be caused by genes passed down in families. A rare condition called hereditary hemorrhagic telangiectasia (HHT) affects the blood vessels. The main symptom is repeated nosebleeds that seem to come out of nowhere and get worse over time.

  https://en.wikipedia.org/wiki/Nosebleed

  An increase in blood pressure (e.g. due to general hypertension) tends to increase the duration of spontaneous epistaxis. […] Anticoagulant medication and disorders of blood clotting can promote and prolong bleeding. […] The vast majority of nosebleeds occur in the front anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach’s plexus). […] Posterior bleeds are often prolonged and difficult to control. They can be associated with bleeding from both nostrils and with a greater flow of blood into the mouth. […] Nosebleeds can be a sign of cancer in the sinus area, which is rare, or tumors starting at the base of the brain, such as meningioma.

  The most frequent symptom of HHT is severe nosebleeds, but the condition also causes abnormal blood vessels in other parts of the body. […] Other things to consider are tumors, both benign and malignant, that can form in the nose or the sinuses. […] If a nosebleed is severe enough that it can fill up a cup with blood, then we are in the territory of something where urgent medical attention is necessary. […] For more troublesome cases, a quick application of silver nitrate in the doctor’s office can put a stop to the nosebleed. […] Essentially the silver ions in the silver nitrate are released around the blood vessels and cause an inflammatory reaction that creates scarring in the little arteries and veins in the nose.

• #1 Nosebleeds While Pregnant: Causes, Prevention & Treatment

  https://my.clevelandclinic.org/health/symptoms/22342-nosebleeds-while-pregnant

  Nosebleeds during pregnancy are normal and usually not a cause for worry. Most nosebleeds are caused by an increase in blood volume and hormonal changes. […] Being pregnant makes you more prone to nosebleeds because the blood vessels in your nose expand due to the pressure of all the new blood moving throughout your body. Your blood supply increases by as much as 50% when you’re pregnant. The blood vessels in your nose are incredibly delicate and break easily. […] The changes in your body that happen during pregnancy can cause a nosebleed. There are a few reasons this happens: Increase in blood volume: When you become pregnant, the amount of blood in your body increases dramatically. This increase in blood volume causes the delicate blood vessels in the lining of your nose to burst more easily under the pressure. Hormonal changes: Hormonal changes can cause a lot of symptoms in pregnancy. Your nose might be more congested or stuffy. The same hormones that thicken the lining of your uterus can impact the mucus membranes in your nose, making them more prone to bleeding. Dehydration: It’s easier to become dehydrated when you’re pregnant because you require more water. When you get dehydrated, the mucus membranes in your nose become dry and cracked. This could be a cause of nosebleeds during pregnancy. Allergies or colds: The blood vessels in your nose become easily irritated and inflamed if you have seasonal allergies or a cold. This makes them prone to breaking open. A condition called pregnancy rhinitis (the swelling of mucus membranes in your nose) causes congestion and stuffiness primarily in the first trimester. It can also contribute to nosebleeds.

  Systemic causes include various blood disorders and certain types of medications that may thin the blood. Patients with high or poorly controlled blood pressure are at higher risk for nasal bleeding because the blood vessels are more likely to burst when they are under high pressure. […] Other conditions associated with nose bleeds include liver disease (which makes platelets that are necessary for clotting not as effective), and primary bleeding disorders, such as Von Willebrands disease. […] If you experience recurrent nose bleeds, or have had a severe one that is difficult to stop, please consider an evaluation by a trained expert, i.e. Ear Nose Throat specialist, that can better evaluate the entire nasal cavity by performing a quick painless in office procedure called a nasal endoscopy to better determine potential causes and treatment options.

• #2 Nosebleeds

  https://www.rch.org.au/kidsinfo/fact_sheets/nosebleeds/

  Nosebleeds are very common in children. A nosebleed (also called epistaxis) occurs when a small blood vessel in the lining of the nose bursts. The inside of the nose is delicate and the small blood vessels are fragile and close to the surface. This means they can burst easily, and start bleeding. […] Nosebleeds often caused by harmless activities such as your child picking their nose, blowing it too hard or too often, or from getting knocked on the nose during play. […] Other causes of a nosebleed may include: overly sensitive blood vessels that burst and bleed in warm, dry weather, infections in the nose, throat and sinuses (e.g. common cold), allergies (e.g. dust mite allergy or hay fever), a foreign body in the nose (e.g. when a child has pushed something up their nose), constipation (e.g. excessive straining when going to the toilet), certain medications (e.g. anti-inflammatory medicines or nose sprays), an underlying medical problem, but this is very uncommon.

  https://www.uptodate.com/contents/causes-of-epistaxis-in-children

  Causes of epistaxis in children […] The epidemiology and etiology of epistaxis in children will be reviewed here. […] An increased incidence of epistaxis occurs during hot or cold weather and when ambient humidity is low, all of which make the nasal septal mucosa dry and friable, and predisposed to bleeding, even with minor trauma as may occur with nose rubbing, blowing, or sneezing. […] The nose is a highly vascular structure. This property enables it to filter, humidify, and warm inhaled air, but also predispose it to bleeding. […] Kiesselbach plexus (also called Little’s area) in the anterior nasal septum is one of the most vascular areas in the nose. It is formed by the anastomosis of terminal vessels from the internal and external carotid arteries. Specifically, the septal branch of the anterior ethmoidal artery, the lateral nasal branch of the sphenopalatine artery, and the septal branch of the superior labial branch of the facial artery all end in the Kiesselbach plexus. In addition, the branches of the sphenopalatine artery supply the posterolateral wall and posterior choana; these vessels are the most likely source of posterior nosebleeds.

  https://entkidsadults.com/nose-epistaxis/

  Epistaxis (nosebleed) is the medical term for bleeding from the nose, nasal cavity, or nasopharynx. It is a common occurrence in patients of all ages, although the causes can vary widely. […] Most episodes of epistaxis come from an area in the anterior nasal septum called Kiesselbachs Plexus, or Littles Area. Several different arteries come together in this area, making the blood supply dense and prone to bleeding. Less commonly, bleeding can come from the nasal turbinates or from the posterior nasal cavity near the sphenopalatine artery. […] In children, the most common cause of epistaxis is digital trauma, or nose picking. In adults, epistaxis is more commonly caused by high blood pressure or blood thinning medications. Other causes affecting patients of all ages include allergies, sinus infections, environmental conditions like dry weather or high altitudes, systemic medical conditions, bleeding disorders, or nasal tumors.

  If the home remedies and prevention recommendations discussed above do not work and a nosebleed continues or worsens, you should seek medical attention. […] The first step in managing a nosebleed is to determine where the blood is coming from, says McAvinew. First we will examine the front (anterior) portion of the nose with a nasal speculum to look for scabs, crusting or exposed blood vessels that may be the source of the bleeding. Anterior bleeds are the most common, accounting for up to 90 percent of nosebleeds. […] Even if the blood source is confirmed to be in the front of the nose, I almost always perform nasal endoscopy to verify that there are no sources of bleeding in the back (posterior) portion of the nose. Posterior bleeds are harder to stop, are usually high volume and can be more dangerous.

  Systemic causes include various blood disorders and certain types of medications that may thin the blood. Patients with high or poorly controlled blood pressure are at higher risk for nasal bleeding because the blood vessels are more likely to burst when they are under high pressure. […] Other conditions associated with nose bleeds include liver disease (which makes platelets that are necessary for clotting not as effective), and primary bleeding disorders, such as Von Willebrands disease. […] If you experience recurrent nose bleeds, or have had a severe one that is difficult to stop, please consider an evaluation by a trained expert, i.e. Ear Nose Throat specialist, that can better evaluate the entire nasal cavity by performing a quick painless in office procedure called a nasal endoscopy to better determine potential causes and treatment options.

  In addition, the provider may order imaging exams and blood tests to rule out certain rare causes for recurrent nosebleeds. […] Nosebleeds are most often treated with nasal packing. A tampon-like device, which may be infused with clotting medication, is inserted into the nose and the patient is usually sent home with the packing in place. Depending on the type of packing used, they will be advised when to see their provider for removal. […] If the bleeding is coming from the back of the nose, people are less likely to be sent home with nasal packing. Because posterior bleeds often involve major arteries, they can be more serious and harder to manage. Patients may be hospitalized and closely monitored until the bleeding can be controlled.
