Gastrointestinal colds in young children can generally be cured in about 7 days, mainly manifested as diarrhea, abdominal pain, bloating, nausea, vomiting, etc.. Similar to the common cold, the gastrointestinal flu is mainly caused by viral infection and is self-limiting, with the entire course of the disease lasting about 1 week. Because some gastrointestinal colds can coexist with the common cold, patients may have gastrointestinal symptoms, but also cough, phlegm, fever and other symptoms, if not treated in time, it may develop into pneumonia, so it is important to go to the gastroenterology department of the hospital for treatment in a timely manner after suffering from gastrointestinal colds. Generally, the gastrointestinal flu will start to improve gradually after about 2-3 days of oral medication, and it will be cured after about 7 days of treatment. In addition, patients with gastrointestinal flu need to pay attention to avoid fatigue and staying up late, strengthen nutrition, clean diet and eat easily digestible food. If the diarrhea is more frequent, you can take montelukast under the guidance of your doctor.
