Gastrointestinal colds are mostly caused by coxsackievirus infection and are upper respiratory tract infections with gastrointestinal symptoms as the first manifestation, often accompanied by bacterial infections, and have a certain possibility of self-healing, but the self-healing time varies from person to person. If the patient is in good general condition and has mild symptoms, he/she can usually heal by himself/herself in about 7 days through proper rest, diet and active rehydration. If the patient has heavy symptoms, high fever, dehydration, electrolyte disorders, or combined with basic diseases, senior citizens and other people, they should go to the hospital internal medicine department for treatment as soon as possible, rather than blindly waiting for self-healing and delaying the disease, which is even life-threatening in serious cases. Spring is a high season for gastrointestinal colds, so you should pay attention to washing your hands, drinking more water, increasing and decreasing clothing in time when the temperature changes, and enhancing physical exercise to improve your ability to fight diseases.
