Gastrointestinal flu is usually induced by infection with viruses and other factors, and it is usually possible to eat sugar in small amounts.
After a virus infects the upper respiratory tract and causes inflammation of the throat, it is swallowed into the stomach and intestines along with saliva, resulting in gastrointestinal discomfort such as nausea, vomiting, bloating, and diarrhea.
Usually it is possible to eat sugar in small amounts for gastrointestinal colds. This is because sugar provides energy for the body. Especially when patients with gastrointestinal colds are hungry, they can eat some sugar, which can prevent the accident of hypoglycemia or fainting caused by excessive hunger. When vomiting or diarrhea caused by gastrointestinal cold, you can also drink a small amount of sugar water in time, which can prevent the patient from dehydration.
To summarize, it is possible to eat a small amount of sugar for gastrointestinal colds. If gastrointestinal flu exists, it is recommended to go to the hospital as soon as possible, and give the relevant examination with the help of the doctor.
