Why is fasting recommended for acute gastroenteritis?

Acute gastroenteritis is an acute inflammation of the gastric and intestinal mucosa, which can manifest as nausea, vomiting, and diarrhea. On the first day of the illness, it is necessary to abstain from food and drink, as any stimulation from food or water can aggravate the inflammation of the gastrointestinal tract and increase the burden on the intestines. Therefore, at the onset of the illness, it is crucial to abstain from food and drink and to actively treat with medication, such as anti-diarrheal agents and antibiotics. As the condition progresses and treatment continues, it is appropriate to gradually reintroduce food, starting with easily digestible foods such as rice porridge, millet porridge, vegetable soup, and rice soup. It is still advisable to avoid hard, raw, cold, and spicy foods.

Can I eat apples with acute gastroenteritis?

Apples are one of the essential fruits in our daily life, containing a rich array of nutrients, such as minerals, fruit acids, vitamins, fiber, etc., which are greatly beneficial to our human body. Acute gastroenteritis is usually caused by exposure to cold or improper diet, primarily characterized by symptoms such as abdominal pain, diarrhea, vomiting, and sometimes fever and chills. In this case, targeted treatment should be firstly applied, and the diet should consist mainly of light and easily digestible food, such as porridge and soft noodles, while avoiding raw, greasy, spicy foods, and alcoholic beverages. Apples are relatively cold in nature; it is best to avoid eating them raw under these circumstances. If there is a real desire to eat apples, steaming them before eating should be feasible.
