  Symptoms of intestinal obstruction usually include cramping pain in the abdomen, accompanied by bloating and loss of appetite. Pain tends to come in waves and eventually becomes continuous. Vomiting is common with obstruction of the small intestine but is less common and begins later with obstruction of the large intestine. […] Complete obstruction causes severe constipation, whereas partial obstruction may cause diarrhea. […] With strangulation, pain may become severe and steady. A fever is common and is particularly likely if the intestinal wall ruptures. […] With volvulus, pain often begins abruptly.

  You may have sharp stomach pains that come in waves. Eventually, the pain may become constant. You may also have one or more of these symptoms: […] A bowel obstruction can feel different depending on which intestine is affected and whats happening in your gut. […] Regardless of the specifics, if youre having severe cramping alongside symptoms like bloating and vomiting, seek immediate care. […] Its possible. It depends on where the blockage is and how serious it is. For example, while pooping may be more difficult, you may still have stool with a partial bowel obstruction. Pooping and even passing gas will likely be impossible with a complete bowel obstruction. […] Most people with bowel obstructions improve after treatment. Being able to pass gas again, feeling less bloated and being able to have bowel movements again are all signs your bowel obstruction is clearing. […] On the other hand, if an obstruction causes a rupture, the condition can be life-threatening. Its essential to seek care as soon as you notice symptoms to get treated before a complication happens.

  https://www.merckmanuals.com/professional/gastrointestinal-disorders/acute-abdomen-and-surgical-gastroenterology/intestinal-obstruction

  Obstruction of the small bowel causes symptoms shortly after onset: abdominal cramps centered around the umbilicus or in the epigastrium, vomiting, and in patients with complete obstruction obstipation. […] Severe, steady pain suggests that strangulation has occurred. […] In the absence of strangulation, the abdomen is not tender. […] Shock and oliguria are serious signs that indicate either late simple obstruction or strangulation. […] Obstruction of the large bowel usually causes milder symptoms that develop more gradually than those caused by small-bowel obstruction. […] Increasing constipation leads to obstipation and abdominal distention. […] Physical examination typically shows a distended abdomen with loud borborygmi. […] Volvulus often has an abrupt onset. Pain is continuous, sometimes with superimposed waves of colicky pain. […] Strangulating obstruction can progress to infarction and gangrene in as little as 6 hours. […] Prolonged obstruction can cause bowel ischemia, infarction, and perforation.

  Obtain the patient’s history of bowel movements, flatus, obstipation (ie, no gas or bowel movement), and associated symptoms. Attempt to distinguish complete bowel obstruction from partial obstruction, which is associated with passage of some gas or stool. Also inquire about the patient’s current and past history in an attempt to determine the most likely cause. […] Major complaints in patients with large-bowel obstruction (LBO) include abdominal distention, nausea, vomiting, and crampy abdominal pain. An abrupt onset of symptoms makes an acute obstructive event (eg, cecal or sigmoid volvulus) a more likely diagnosis. A history of chronic constipation, long-term cathartic use, and straining at stools implies diverticulitis or carcinoma. […] Changes in the patient’s caliber of stools strongly suggest carcinoma. When associated with weight loss, the likelihood of neoplastic obstruction increases.

• #1 Bowel Obstruction: Signs and Symptoms

  https://www.health.com/bowel-obstruction-symptoms-7693186

  Bowel obstruction is a partial or complete blockage in the small intestine or large intestine (colon). The part of the intestine above the obstruction functions normally, while the area with the blockage enlarges as it fills with a buildup of food, fluids, gas, and stool. This leads to symptoms such as abdominal pain, constipation, vomiting, bloating, or the inability to pass gas. […] The onset of symptoms can vary, depending on the type of obstruction. You may notice mild abdominal discomfort that comes and goes, gradually intensifying over time, or you may experience severe symptoms that develop suddenly. […] Untreated bowel obstruction can lead to serious illness, including intestinal perforation, bowel necrosis (tissue death), and life-threatening infection. Understanding the symptoms can help you recognize when to seek medical attention and improve your chances of full recovery.

• #1 Small-Bowel Obstruction: Practice Essentials, Background, Pathophysiology

  https://emedicine.medscape.com/article/774140-overview

  Strangulated SBOs are most commonly associated with adhesions and occur when a loop of distended bowel twists on its mesenteric pedicle. The arterial occlusion leads to bowel ischemia and necrosis. If left untreated, this progresses to perforation, peritonitis, and death. […] Morbidity and mortality are dependent on the early recognition and correct diagnosis of obstruction. In general, there is a 10% mortality. If untreated, strangulated obstructions cause death in 100% of patients. If surgery is performed within 36 hours, the mortality rate decreases to 8%. The mortality rate is 25% if the surgery is postponed beyond 36 hours in these patients. […] Complications of SBO also depend on the severity of the condition, the patient’s age, the presence of comorbities and, often, the duration of symptoms/signs, and include the following: Sepsis: Due to translocation of intestinal bacteria from tissue breakdown […] Bowel ischemia/perforation […] Peritonitis […] Acute kidney injury/acute renal failure […] Surgical complications.

• #1 Intestinal obstruction – Diagnosis & treatment – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/intestinal-obstruction/diagnosis-treatment/drc-20351465

  Intestinal obstruction is usually a medical emergency. […] Your doctor will ask about your medical history and your symptoms. […] The doctor may suspect intestinal obstruction if your abdomen is swollen or tender or if there’s a lump in your abdomen. […] If you have an obstruction in which some food and fluid can still get through (partial obstruction), you may not need further treatment after you’ve been stabilized. […] If nothing is able to pass through your intestine, you’ll usually need surgery to relieve the blockage. […] If your doctor determines that your signs and symptoms are caused by pseudo-obstruction (paralytic ileus), he or she may monitor your condition for a day or two in the hospital, and treat the cause if it’s known. […] Paralytic ileus can get better on its own.

  Ogilvie syndrome, also known as acute colonic pseudo-obstruction (ACPO), is a sudden and unexplained paralysis of your colon. Your colon acts like its blocked or obstructed by something (pseudo-obstruction) but nothing is physically obstructing it. The problem is in your colons motor system. It stops moving food along, allowing it to build up inside and causing the walls to dilate (widen). […] When partially digested food and gas begin to build up in your colon, you might experience: Abdominal distension. Abdominal pain. Loss of appetite. Nausea and vomiting. Bloating and gas. Constipation and/or diarrhea. […] The exact cause isnt fully understood, but scientists believe it results from a dysfunction of your autonomic nervous system. This is the part of your nervous system that controls the involuntary muscle movements that regulate your bowels (peristalsis). Since its an acute condition, some unusual stress on your autonomic nervous system probably triggers it. But other health factors also probably contribute.

  Signs and symptoms of intestinal obstruction include: […] Crampy abdominal pain that comes and goes […] Loss of appetite […] Constipation […] Vomiting […] Inability to have a bowel movement or pass gas […] Swelling of the abdomen. […] Because of the serious complications that can develop from intestinal obstruction, seek immediate medical care if you have severe abdominal pain or other symptoms of intestinal obstruction.

  The presence of hypotension and tachycardia is an indication of severe dehydration. […] Conservative management is successful in 40 to 70 percent of clinically stable patients, with a higher success rate in those with partial obstruction. […] Although conservative management is associated with shorter initial hospitalization (4.9 versus 12 days), there is also a higher rate of eventual recurrence (40.5 versus 26.8 percent). […] With conservative management, resolution generally occurs within 24 to 48 hours. Beyond this time frame, the risk of complications, including vascular compromise, increases. If intestinal obstruction is not resolved with conservative management, surgical evaluation is required.

  https://www.webmd.com/ibd-crohns-disease/crohns-disease/bowel-obstruction-and-crohns-disease

  Blockage in your intestines is a common problem with Crohns disease. Crohns causes chronic, meaning ongoing, inflammation. This can thicken your intestinal wall, or make scar tissue from repeated swelling and healing. A stricture forms when the wall narrows. […] Depending on how blocked the passage becomes, a stricture can range from mild to severe. Signs there may be some blockage include: You feel nauseated or start vomiting. Your stomach can get bloated. Your belly might be making loud sounds. You have sharp, cramp-like stomach pains. (These happen when normal bowel sections push against the stricture.) […] Sometimes meds can reduce your swelling enough to ease the blockage. If the obstruction is severe, doesnt respond to meds, or involves scar tissue, surgery might be needed. You’ll also likely need surgery if the condition happens often.

• #2 Intestinal Obstruction: Evaluation and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2018/0915/p362.html

  The pathologic effects of acute intestinal obstruction are fluid and electrolyte imbalances, and mechanical consequences of increased luminal pressure on intestinal perfusion. Fluid loss from emesis, bowel wall edema, and loss of absorptive capacity lead to dehydration. Emesis causes loss of gastric potassium, hydrogen, and chloride, which generates metabolic alkalosis. […] In a low-grade (incomplete) intestinal obstruction, some gas and/or fluid passes beyond the point of obstruction, whereas nothing passes beyond it in a high-grade (complete) SBO. Proximal to the point of obstruction, the intestinal tract dilates, filling with gastrointestinal secretions and swallowed air, and increasing luminal pressures. […] When intraluminal pressure exceeds venous pressures, loss of venous drainage exacerbates edema and congestion of the bowel. This may compromise arterial flow, causing ischemia, necrosis, and ultimately perforation. A closed-loop obstruction, in which a segment of bowel is obstructed proximally and distally, may undergo this process rapidly and is considered a surgical emergency. […] Surgical exploration is recommended in patients who clinically deteriorate at any point during hospitalization and in those for whom three to five days of nonoperative management is ineffective, because the risk of complications in these patients is increased.

  Obstruction of the small bowel causes symptoms shortly after onset: abdominal cramps centered around the umbilicus or in the epigastrium, vomiting, and in patients with complete obstruction obstipation. […] Severe, steady pain suggests that strangulation has occurred. […] In the absence of strangulation, the abdomen is not tender. […] Shock and oliguria are serious signs that indicate either late simple obstruction or strangulation. […] Obstruction of the large bowel usually causes milder symptoms that develop more gradually than those caused by small-bowel obstruction. […] Increasing constipation leads to obstipation and abdominal distention. […] Physical examination typically shows a distended abdomen with loud borborygmi. […] Volvulus often has an abrupt onset. Pain is continuous, sometimes with superimposed waves of colicky pain. […] Strangulating obstruction can progress to infarction and gangrene in as little as 6 hours. […] Prolonged obstruction can cause bowel ischemia, infarction, and perforation.
