Inflammatory bowel disease, mainly including ulcerative colitis and Crohn’s disease, has continued to increase in incidence over the past decade or so, and is therefore of increasing concern to medical professionals and the general public. Ulcerative colitis is a type of inflammatory bowel disease, a chronic non-specific inflammatory disease involving the rectum and colon, with diarrhea, abdominal pain, and mucopurulent stools as the main clinical manifestations. Many patients with ulcerative colitis are very distressed by their condition and are confused about the occurrence, control and prognosis of the disease; (1) Why do I have ulcerative colitis? Many patients have the question, why do they have ulcerative colitis while others do not have the disease? In fact, so far the etiology and pathogenesis of inflammatory bowel disease are not yet clear, it may be related to the interaction of a variety of factors; ulcerative colitis has a high incidence in Europe and the United States, familial, and there are significant differences in the incidence between races, so it has been suggested that the disease may be related to genetics. Many clinical patients with ulcerative colitis have mental anxiety and stress, excessive stress may cause disorders of the vegetative nerves, intestinal motility disorders, vasoconstriction, ischemic damage to intestinal wall tissues leading to inflammation and ulcer formation, so mental and psychological factors may lead to the occurrence of ulcerative colitis; intestinal mucosal immune system also has an important role in the occurrence and development of ulcerative colitis, the application of glucose The immune system of the intestinal mucosa also plays an important role in the development of ulcerative colitis, and the application of corticosteroids and immunosuppressants is effective in the treatment of ulcerative colitis, so the occurrence of ulcerative colitis may also be related to autoimmune factors, and diet, smoking, and infection may be factors that lead to the occurrence of ulcerative colitis; (2) What should patients with ulcerative colitis pay attention to in their diet? Patients with ulcerative colitis should pay attention to dietary regimen. The actual food is not suitable for ulcerative colitis patients, especially during the active period. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Such foods are leeks, celery, white potatoes, radishes, coarse grains, dry beans, etc. ② seafood and dairy products: the protein in seafood is different from the protein in the food we often eat, certain xenobiotics are prone to allergies and aggravate inflammatory reactions, so ulcerative colitis patients must be cautious about eating seafood. It is also not recommended to drink milk and dairy products during the active period of the disease. ③ Stimulating foods: Spicy and irritating foods can cause adverse stimulation of the gastrointestinal tract, so ulcerative colitis patients should refrain from eating spicy and irritating foods such as chili, mustard and wine, and eat less garlic, ginger and green onions. Also do not eat too cold, too hot food. ④ greasy food: ulcerative colitis diarrhea is often accompanied by fat malabsorption, severe cases with steatorrhea. Therefore the amount of dietary fat should be limited, diarrhea should not eat more oil food and fried food, cooking a variety of dishes should be as little oil as possible, and often use steam, boil, stew, blanch, stew, water slide and other methods. (3) Can ulcerative colitis be cured? The most important concern for most patients is whether ulcerative colitis can be cured. The majority of patients will have recurring episodes of ulcerative colitis, mild and long-term remission have a better prognosis, acute flare-ups, complications and those older than 60 years have a poor prognosis, for ulcerative colitis patients to control the diet, work and rest, warm and cold, eliminate tension, appropriate physical exercise, enhance physical fitness, avoid intestinal infections, etc. may reduce the recurrence rate of the disease. Most patients with mild to moderate ulcerative colitis are treated with SASP to induce remission and half-dose maintenance therapy, while patients with moderate to severe ulcerative colitis can be treated with hormone or immunosuppressant to induce remission, followed by SASP or immunosuppressant maintenance therapy, and most of the maintenance therapy takes 3 years; some patients need lifelong maintenance.
