Colds and diarrhea are common in a special type of upper respiratory tract infection: gastrointestinal colds. At this time, it is recommended not to eat any food for the time being, and try to let the gastrointestinal tract have time to repair itself and rest. If necessary, symptomatic medications can be taken, such as probiotics, such as Bifidobacterium bifidum quadruple live bacterial tablets, lactobacillus tablets, etc.; as well as Chinese medicines to strengthen the spleen and the stomach, such as spleen oral liquid, spleen oral liquid, etc.. If you cannot eat or take medicine, and the symptoms are relatively serious, you can use intravenous drip to give medicine. If necessary, blood routine and stool routine should be tested to clarify the cause of the disease, and corresponding etiologic treatment should be carried out.
