Crohn's disease has a certain genetic predisposition, but not all cases of Crohn's disease are inherited from one generation to the next. Current research indicates that its occurrence is related to environmental factors, immune factors, and genetic factors, with a higher incidence in males than in females. The prevalence of Crohn's disease is not particularly high in China. Symptoms are primarily abdominal pain, diarrhea, intestinal obstruction, and nutritional disorders. Some cases may also involve complications such as iridocyclitis, clubbing arthritis, oral mucosal ulcers, and chronic hepatitis. It is important to rest adequately and adjust your diet, favoring frequent light meals, low in fat and high in calories.

Common Complications of Crohn's Disease

Crohn's disease is an inflammatory bowel disease that commonly leads to complications such as intestinal obstruction, acute perforation, rectal bleeding, and poor absorption syndrome due to intra-abdominal abscesses. Due to inflammation, there is an increase in intestinal mucosa and narrowing of the intestinal lumen, which makes intestinal obstruction more likely. The decrease in protective barrier function of the intestinal mucosa makes it susceptible to acute perforation, which can also lead to rectal bleeding when perforated. Examinations for Crohn’s disease include colonoscopy, barium enema, CT scans, complete blood count, and intestinal absorption tests. The treatment involves a combination of medication and surgery, as the exact cause of the disease is not very clear, and it tends to have a prolonged course with recurrent flare-ups, making it difficult to cure completely.

Crohn's disease affected areas

Crohn's disease is an inflammatory bowel disease that can occur in any part of the gastrointestinal tract, primarily affecting the right half of the colon and the terminal ileum. Typical clinical manifestations include abdominal pain, intestinal obstruction, diarrhea, and some extraintestinal manifestations such as nutritional disorders or fever. Complications can include intra-abdominal abscesses, acute intestinal perforation, significant intestinal bleeding, malabsorption syndrome, and can also involve the liver, skin, joints, and other areas. The course of the disease is relatively long and prone to recurrent episodes. Treatment primarily targets complications, focusing on pharmacological and surgical interventions. It is important to enhance nutritional support by providing high-nutrition, low-fat foods.

Can people with Crohn's disease eat eggs?

Crohn's disease is an inflammatory bowel disease, and patients can eat eggs. The principle of the diet is to eat small meals frequently and keep it low in fat, eating more vegetables such as carrots, potatoes, and yams. Avoid cold, spicy, and gas-producing foods such as chili peppers, radishes, leeks, and soy products. Crohn's disease can easily affect joints, skin, and other organs, and the course of the disease tends to be recurrent and is not easy to cure completely. The current treatment principle primarily involves medication combined with surgical treatment to prevent complications, with a focus on rest, a high-nutrition, low-fat diet, and correcting electrolyte imbalances.

How serious is Crohn's disease exactly?

Crohn's disease is an inflammatory bowel disease that can cause intestinal absorption disorders, malnutrition, and decreased body resistance leading to fever. The inflammation of the intestines can trigger abdominal pain, diarrhea, or bowel obstruction, and ischemic necrosis of the intestinal wall can lead to perforation and bloody stools. It can also affect other organs such as joints, liver, and skin, causing damage. Currently, the cause of Crohn's disease is not well understood, and it tends to have a long course, with frequent relapses and is difficult to cure completely. The current treatment methods combine pharmacotherapy with surgical techniques to treat complications and minimize damage to organs.

Can Crohn's disease be seen on a CT scan?

Crohn's disease cannot be determined solely by CT scans. A CT scan can be used to assess the general situation, which should then be combined with personal clinical symptoms, routine stool tests, and ideally, colonoscopy and blood tests to make an accurate diagnosis. Crohn's disease is an idiopathic disease, currently thought to be related to genetic factors, and inevitably linked to individual immune factors and dietary habits. A definitive diagnosis can be made through colonoscopy and pathological examination. Care should be taken to avoid consuming raw, cold, hard, spicy, and irritating foods.
