The main symptoms are abdominal pain, nausea and vomiting, as well as cold symptoms such as increased body temperature and chills. Since gastrointestinal flu can cause severe diarrhea, patients often suffer from dehydration and electrolyte disorders due to untimely treatment, and it is recommended to go to the hospital for treatment in a timely manner in serious cases. If found in the early stage, oral Chinese medicines such as Huo Xiang Zheng Qi Shui can effectively treat and improve various symptoms caused by gastrointestinal flu. It is also less common in intestinal infections such as intestinal tuberculosis, where patients have low fever, night sweats, chills and stomach pain, but patients with intestinal tuberculosis have a long course of illness combined with wasting, loss of appetite and systemic symptoms, most typically intensifying after eating and decreasing after defecation.
