  Crohn’s disease can affect any area in the GI tract, but it’s mostly found in the large and the small intestine. […] Symptoms can range in severity and it can depend on the area of the GI tract that’s affected. […] The symptoms can come on gradually, but they can also show up suddenly. And these can include diarrhea, fever, fatigue, abdominal pain and cramping, blood in your stool, mouth sores, reduced appetite and weight loss. […] In more severe cases, you may have inflammation of the eyes, skin, joints, liver or bile ducts, kidney stones, and anemia. […] Over time, Crohn’s disease can lead to other complications, including bowel obstruction, ulcers, fistulas, anal fissures, malnutrition, and other health problems. […] Crohn’s disease is a type of inflammatory bowel disease (IBD) that causes swelling and irritation of the tissues, called inflammation, in the digestive tract. This can lead to belly pain, severe diarrhea, fatigue, weight loss and malnutrition.

  A low-grade fever is more typical of Crohn disease. A different pathology, such as an intraabdominal abscess, must be suspected in the presence of a high-grade fever. Weight loss often develops due to diarrhea and fear of eating. […] Involvement of these small bowel regions often causes malabsorption and steatorrhea. Nutritional deficiencies consequently arise, compounded by poor eating. […] More characteristic of this condition are manifestations like hematochezia, pain on defecation, reduced rectal wall elasticity, incontinence, anorectal pain and fistulae, perirectal abscesses, anal strictures, and hemorrhoidal tags. […] Upper gastrointestinal tract symptoms are more common in patients with this condition than in the other forms of Crohn disease. Such symptoms include emesis, nausea, and epigastric pain. Gastric ulcer diagnostic workups are likely to reveal the absence of H pylori. Upper gastrointestinal obstruction is common.

  Other symptoms which may show when Crohn’s is active are night fevers, joint inflammation (arthritis), inflamed eyes, erythma nodosum (painful boil like lumps that usually appear on the shins), rashes and eruptions on any part of skin. It is very rare but occasionally genital areas may also be affected. Most of these symptoms are responsive to treatment given for Crohn’s so should clear up once Crohn’s is under control but if any continue, they should be reported to the specialist team as soon as possible. […] Some children with Crohn’s disease have delays in height and puberty. This is due to a combination of factors, including the inflammation itself, loss of nutrients, steroid treatment, and hormonal changes. It is important to actively monitor growth during childhood, especially during puberty. With treatment, some will continue to grow in height into their twenties, long after the onset of puberty, and long after their peers have stopped growing.

• #1 Crohn’s Disease Severity and Progression

  https://www.crohnsandcolitis.com/crohns/severity-and-progression

  A progressive disease is a condition that can get worse over time like Crohns. As it progresses, the chronic inflammation in the intestines may lead to complications such as strictures, fistulas, and abscesses. […] With Crohns, inflammation can affect any part of the gastrointestinal (GI) tract. Additionally, in many cases Crohns can progress over time, causing more inflammation. This active inflammation may lead to more symptoms and more severe disease. […] Before a gastroenterologist can determine the severity of Crohn’s, there are a few factors taken into consideration. From the symptoms experienced, complications, to how much the disease has impacted your life. […] A goal in treating Crohns, no matter the severity, is managing symptoms by reducing inflammation. A gastroenterologist can help by identifying a treatment plan that could help reduce inflammation and relieve symptoms. Long-term treatment goals include improving the intestinal lining and preventing the occurrence of disease complications.

  The initial lesion starts as an infiltrate around an intestinal crypt. Ulceration then develops, initially involving only the superficial mucosa but later growing into the deeper layers. Noncaseating granulomas develop with continuing inflammation, spreading toward the intestinal wall. […] Years of recurrent inflammation typically lead to fibrostenosis and stricture formation in the ileocecal area. Diarrhea is later replaced by chronic bowel obstruction. Ileocecal wall thinning eventually occurs, leading to microperforation and fistula formation into nearby organs. […] Crohn disease manifests variably, depending on the area involved. Patients initially report recurrent episodes of mild abdominal pain, diarrhea, flatulence, and fever with intervening asymptomatic periods lasting weeks to months. Emotional or physical stress often precipitates the „flare” or „flare-up” symptoms. More serious, localizing signs start to appear after repeated flare-ups.

  Crohns disease is characterised by inflammation of one or more areas of the digestive tract, with normal areas of gut between. It can occur anywhere from the mouth to the anus, but most commonly in the large and small bowel (intestine). This inflammation may lead to ulceration, abscesses and strictures in the bowel.

[…] These can vary. More common symptoms include severe stomach pain, vomiting, nausea, dramatic weight loss, persistent diarrhoea (possibly with blood and/or mucus), and in some cases, constipation. These symptoms can either appear very suddenly, or very slowly, with weeks or months of good health in-between. Children often present initially with just one or two of these symptoms. As they mimic other less serious childhood conditions, diagnosis can be very difficult. In some cases, the symptoms may not point to bowel disease with a child just feeling very tired with a loss of appetite, joint pains, skin rash or slowed growth.
