Some clinical patients have diarrhea when they drink cold ones. Such people should pay attention to their diet and try to avoid eating raw and cold foods to avoid stimulating the mucous membrane of the gastrointestinal tract, which can effectively reduce the occurrence of this symptom. Diarrhea symptoms when eating raw and cold food are considered to be mainly related to weak spleen and stomach, irritable bowel syndrome, enteritis, etc. 1. Weak spleen and stomach: When the patient’s spleen and stomach are weak, eating cold, spicy and stimulating food can easily stimulate the gastric mucosa, resulting in abdominal pain and diarrhea. Patients can improve through traditional Chinese medicine, such as taking Ginseng Jianshuwan, Ginseng Guixinwan, Tengzhong Yiqiwan and other herbal medicines that strengthen the spleen and eliminate food, tonify the middle and benefit the stomach, or acupuncture with moxibustion Jianli, Liangmen, Tianshu, Foot Sanli and other acupuncture points under the guidance of a doctor. In daily life, patients should be regulated by paying attention to the regular diet, regular rationing of three meals, and eating more vegetables and fruits; 2. Irritable bowel syndrome: prone to abnormal intestinal dynamics, when eating raw and cold food, patients’ gastrointestinal peristalsis is enhanced, triggering diarrhea and abdominal pain, etc. Some patients may have accompanying symptoms such as indigestion and heartburn. Patients should go to the hospital promptly and use antispasmodics such as piviramine and trimethoprim to relieve intestinal spasm and drugs such as montelukast to relieve diarrhea symptoms as prescribed by the doctor; 3. Enteritis: If the patient has enteritis, eating raw and cold food will stimulate the intestinal mucosa and cause disorders in the structure and function of intestinal flora, leading to diarrhea. When the symptoms of diarrhea are mild, oral rehydration salts can be taken to replenish body fluids. In case of severe symptoms, intravenous rehydration is required to maintain electrolyte balance and avoid dehydration.
