Frequent diarrhea and diarrhea can be caused by two aspects: 1. inflammatory infections, cold, flu, etc. leading to enteritis conditions. 2. dysfunction of the plant nervous system, leading to irritable bowel syndrome conditions. The former is mostly viral and bacterial infections that cause congestion and edema of the intestinal mucosa, followed by an increase in the number of diarrhea, causing an increase in vascular permeability, resulting in diarrhea and diarrhea symptoms. In general, this condition requires rehydration, anti-inflammatory and symptomatic support treatment. If accompanied by fever, symptomatic treatment such as rehydration needs to be actively given. In the latter case, most of them are insomnia, worry, stress, emotions, etc., which lead to endocrine disorders or plant nervous disorders, causing functional gastrointestinal disease and resulting in irritable bowel syndrome. In this case, it is necessary to pay more attention to rest, pay attention to the combination of work and rest, and at the same time, give appropriate drugs to regulate the plant nerve function and improve the gastrointestinal dynamics, such as haloperidol melitrexin tablets, glutathione tablets and other symptomatic treatment.
