Symptoms of diarrhea and fear of cold: The first point that comes to mind is the gastrointestinal flu. Gastrointestinal flu, first of all, is a decrease in the function of the gastrointestinal tract, causing nausea, vomiting and, most commonly, diarrhea. At this time, the body function is weakened, and at the same time there may be some low fever, so there will be chills. Usually, when this kind of gastrointestinal cold occurs, it is recommended to first eat a simple diet, which can promote the body’s absorption and will not cause stress to the gastrointestinal tract. The second point is that you can use some medicines, the common ones are Huo Xiang Zheng Qi water and Huo Xiang Zheng Qi tablets. For those who are uncomfortable with such preparations containing alcohol as Huo Xiang Zheng Qi water, you can try Huo Xiang Zheng Qi tablets or capsules, and after treatment by diet as well as medicine, the phenomenon of gastrointestinal cold will gradually slow down or even disappear, and the gastrointestinal cold may be cured.
