Symptoms of gastrointestinal flu usually include vomiting, diarrhea, abdominal pain, fever and headache.
1. Vomiting: Usually when patients have gastrointestinal flu, viruses and bacteria will invade the stomach and intestines, resulting in abnormal secretion and contraction of the stomach and vomiting of stomach contents upward.
2. Diarrhea: usually due to the invasion of the stomach and intestines by viruses and bacteria, the intestines and stomach will be stimulated to produce a large amount of secretion, affecting intestinal absorption, and intestinal peristalsis will also increase, resulting in diarrhea.
3. Abdominal pain: the increased number of intestinal peristalsis may lead to intestinal spasm, which causes abdominal pain; it may also be due to the redness and swelling of the mucous membrane on the intestinal wall, leading to abdominal pain.
4. Fever and headache: Generally viruses will invade the intestinal tract and cause fever and other symptoms, and gastrointestinal flu is also easy to induce acute headache and other symptoms.
If patients have the above symptoms, it is recommended to actively seek medical treatment and regular treatment under the guidance of professional doctors.
