Fever symptoms caused by digestive tract infections are mainly due to inflammatory irritation. In addition to treating the fever symptoms, the digestive tract infection itself should also be treated. First, treatment with anti-infective drugs, including some penicillin or cephalosporin, can be used. Some anti-inflammatory drugs can also be used, including ciprofloxacin and ofloxacin. Secondly, some antipyretic drugs can be used to reduce fever, including new compound daphylline and ibuprofen. In addition, patients should pay attention to improving their diet and drink more hot water to facilitate the elimination of toxins. Since digestive tract infections can cause weakness of the stomach and intestines, it is important to eat more fresh fruits and vegetables, and not to eat cold and spicy foods.
