Chronic gastroenteritis primarily manifests as chronic inflammation of the stomach and intestines, which can include chronic abdominal pain, diarrhea, and decreased appetite. Due to poor appetite and impaired digestive absorption, symptoms such as physical emaciation, fatigue, and lethargy can occur, making one more susceptible to catching colds. For chronic gastroenteritis, it is important to adjust the imbalance of gut flora and use antibiotics to control infections. Attention should be paid to a light, regular diet, eating three meals at fixed times and amounts, avoiding greasy and spicy foods, and consuming more light vegetables and fruits.
