Patients with diarrhea usually have an increase in the number of bowel movements, abdominal pain, loss of appetite, and even a serious impact on life and work. Diarrhea in daily life is mostly caused by improper diet, cold in the abdomen, and poor digestive function of the stomach and intestines. Treatment is mainly symptomatic for the cause. First of all, diarrhea can lead to massive dehydration and electrolyte disorders in the body due to a large number of repeated bowel movements, so the first thing is to carry out rehydration treatment and replenish appropriate electrolytes through intravenous drips and other means. Secondly, if abdominal pain is obvious and there is obvious intestinal spasm, it is necessary to take antispasmodic and analgesic drugs to relieve the pain symptoms in time. At the same time, take antidiarrheal drugs, such as some drugs with the effect of clearing heat, relieving dampness, moving Qi and regulating intestinal flora. In addition, some antiviral and antiseptic drugs can be taken to fight infection and inhibit the growth of intestinal bacteria.
