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.
