1, milk: milk is rich in a variety of essential nutrients and vitamins, is a commonly loved food. However, most patients with chronic colitis should not drink it. Some particularly sensitive patients will soon have intestinal tinnitus and diarrhea after drinking. The reason is that although milk has the effect of “replenishing the deficiency and strengthening the spleen and stomach”, it has the effect of “slipping the colon”, so chronic colitis patients should be cautious about taking milk. 2, fruits: mainly refers to a variety of fresh fruits, such as watermelon, melon, cucumber, bananas, peaches, persimmons, loquat, raw pears, etc.. Although melons and fruits are rich in vitamins, minerals, inorganic salts and other nutrients, but for most patients with chronic colitis, also in the list of contraindications. The reason is that most of the melons and fruits are cold in nature, which can damage the spleen and Yang, and easy to breed dampness, trapping the transport function of the spleen and stomach, and some have the effect of slippery intestines, which leads to frequent diarrhea, affecting the effectiveness of the treatment. Many patients often eat watermelon in the summer will cause diarrhea, is an obvious example. 3, greasy food: mainly refers to meat and oil food, such as braised meat, ribs, meat-filled buns, wontons and chicken, duck stewed soup, etc.. These foods contain animal fats, chronic colitis patients eat, there is often an increase in the number of bowel movements, so they should not be eaten. 4, treatment suggestions: for chronic colitis long-term patients or willing to repeatedly patients, it is recommended that you can use Chinese medicine for treatment, while pay attention to the diet. Chronic colitis after timely and appropriate treatment, the prognosis is generally good; however, some patients due to repeated intestinal damage and repair under the stimulation of intestinal inflammation, which may eventually lead to the occurrence of tumors. Therefore, it is important for patients with chronic colitis to have proper health care. Usually strengthen exercise, enhance physical fitness, strengthen dietary hygiene and water management; do not eat spoiled food, do not drink raw water, eat raw fruits and vegetables to scald. Pay attention to rest and increase nutrition. In addition, should maintain a relaxed mood, avoid strong stimulation, establish confidence to overcome the disease. 5, avoid mouth: chronic colitis patients often have diarrhea, abdominal pain, bloating, indigestion and other symptoms. The “diarrhea” of chronic colitis belongs to the category of “long diarrhea”, mainly due to spleen deficiency and loss of normal transport function. If a person needs to have a bowel movement whenever there is a mood swing, he or she is suffering from “liver qi offending the spleen”, while a person who needs to have a bowel movement every morning is suffering from “spleen and kidney deficiency”. In the treatment, we need to adopt the methods of warming the spleen yang, detoxifying the liver and strengthening the spleen, and warming the spleen and kidney, together with astringent medicine to stop diarrhea, so that both the symptoms and the root can be treated. However, in the process of treatment, patients also need to “abstain from eating”. Otherwise, although the medicine is right, the treatment effect is not good, or even futile; or there is improvement, but see the condition recurring, so that the previous work is abandoned.
