Watery stools with colds are mainly seen in a special type of upper respiratory tract infection: gastrointestinal colds. The body is invaded by pathogens such as viruses, bacteria, mycoplasma, chlamydia, rickettsia, etc., creating an inflammatory response of congestion, edema, and massive exudation of inflammatory substances from the mucosa of the upper respiratory tract. Through the associated lymphatic system, inflammation can involve the digestive system, causing symptoms of the digestive tract, such as diarrhea, and even nausea, vomiting, and abdominal pain. At this time, you can temporarily avoid eating any food and treat the symptoms by taking appropriate probiotics, Bifidobacterium tetrasporium tablets, and spleen-strengthening oral solution. Test blood routine and stool routine to clarify the cause and adjust the treatment plan.
