Inflammatory bowel disease, or IBD for short, is a specific chronic inflammatory disease of the intestine, which mainly includes Crohn’s disease (CD) and ulcerative colitis (UC). In the past 30 years, the incidence of IBD in China has been on a rising trend. Clinically, patients may present with recurrent abdominal pain, diarrhea, mucus and blood stools, and even various systemic complications, such as blurred vision, joint pain, and joint pain. The patient may experience recurrent abdominal pain, diarrhea, mucus and blood stools, and even various systemic complications such as blurred vision, joint pain, and skin rashes. The disease may improve with treatment or may resolve on its own. However, most patients have recurrent episodes that persist, and a significant number of them require surgical treatment due to complications. Patients with IBD cannot properly absorb carbohydrates, proteins, fats, vitamins and many micronutrients from their intestines, and the inflammation of the intestines or the medications they take may cause poor appetite, so IBD is often accompanied by varying degrees of malnutrition and even affects the normal growth and development of children. There is no special diet for IBD, and the food tolerated by different people varies, so the general dietary principle for IBD is to ensure a balanced diet while avoiding foods that make the disease worse. Avoid smoking, alcohol, spicy and stimulating foods, and avoid eating foods that are too cold or too hot. If intestinal inflammation has caused intestinal stenosis, it is better to eat low fiber, less residue food, or even liquid diet. Of course, in these cases, it is best to adjust the diet under the guidance of a physician until the inflammation subsides. Most experts believe that inflammatory bowel disease is not terrible as long as you adopt a healthy lifestyle, ensure regular eating, rest and medication, and monitor your condition with regular follow-up visits.
