Headache and diarrhea may be caused by gastroenteritis or gastrointestinal flu.
Gastroenteritis is mainly stimulated by pathogenic bacteria and chemicals, which can cause damage to the gastrointestinal mucosa, leading to diarrhea, vomiting and other symptoms. Diarrhea and vomiting can lead to a large amount of fluid loss in the gastrointestinal tract, which in turn can cause dehydration, electrolyte disorders and other abnormalities, which can lead to headaches.
Gastrointestinal flu, mainly due to coxsackie virus infection. As the virus can secrete toxins, it can cause irritation to the cerebral blood vessels, which can lead to headaches. At the same time, gastrointestinal colds can cause digestive disorders and diarrhea.
If you have headache and diarrhea symptoms, you should go to the regular hospital for examination and treatment in time to avoid delaying your condition.
