Crohn's disease is not contagious and its specific causes are not particularly clear. It is an inflammatory bowel disease and can be treated in the gastroenterology department. Typical symptoms include abdominal pain, diarrhea, accompanied by fever and nutritional disorders, among others. It may also be complicated by acute perforation, rectal bleeding, intra-abdominal abscesses, and malabsorption syndrome. The course of the disease tends to be prolonged and recurrent, making it difficult to cure. The clarity and severity of the lesion, the length of the course of the disease, and the rate of recurrence after surgery are related. Because it is not contagious, it cannot be transmitted among the population.

Does Crohn's disease cause swelling of the feet?

Crohn's disease generally does not cause swelling of the feet, but if it causes nutritional disorders, there will be manifestations of swelling of the feet. This is due to hypoproteinemia, which leads to a decrease in the colloid osmotic pressure of the plasma, and the water and fluids in the blood vessels flow out into the tissue fluid, forming swelling in the feet. In addition to foot swelling, there may also be abdominal pain, diarrhea, intestinal obstruction, and fever, and some may affect the liver, joints, or skin. For more noticeable foot swelling, it is appropriate to use diuretics. There is no specific treatment for Crohn's disease; it is mainly treated with medication and surgery to manage its complications and enhance nutritional support. (The use of medication should be under the guidance of a professional doctor.)

Can people with Crohn's disease eat peanuts?

Crohn's disease is a chronic nonspecific inflammatory bowel disease of unknown cause. Its lesions can occur in any part of the digestive tract. The main symptoms include abdominal pain, diarrhea, abdominal masses, fistula formation, and weight loss. Systemic symptoms such as fever and malnutrition can also occur, and intestinal obstruction might require surgical treatment. Currently, there are no specific treatments for this disease, and it has signs of lifelong recurrence, making the treatment very challenging. It is crucial to pay attention to nutrition in the diet, consuming high-nutrition, low-residue foods, and appropriately supplementing with folic acid, vitamins, and other nutrients. The diet should primarily consist of rice and noodles, and it is advisable to consume lean meats, fish, poultry, eggs, and soy products. Peanuts can be eaten in small amounts, but it is not recommended to consume them excessively because they have a high fat content, which is not beneficial for managing Crohn's disease.

What to do if Crohn's disease causes a fever?

Extraintestinal manifestations of Crohn's disease include fever or nutritional disorders. When there is a fever, symptomatic fever-reducing treatment should be applied using antipyretic medications. If the body temperature does not exceed 38°C, physical cooling methods can also be used, such as wiping the palms of the hands, soles of the feet, forehead, armpits, and groin with alcohol or a warm towel to dissipate heat physically. It is important to drink plenty of water and consume more vegetables to maintain hydration. Attention should also be given to enhancing nutrition by providing a high-nutrient, low-fat diet, which could include lean meats, eggs, and fish. Strict rest is crucial during the disease flare-ups to avoid excessive fatigue. (Please use medications under the guidance of a doctor)
