Patients can eat cantaloupe to nourish the kidneys, tonify the qi, clear the lungs, stop coughing and reduce swelling, etc. It is suitable for patients with kidney disease, stomach disease, cough, phlegm and asthma, anemia and constipation. Hami melon is cold in nature and is not suitable for patients with bloating and diarrhea during the acute phase of gastroenteritis. At the same time, patients are advised to give warm, easily digestible food as the main diet on weekdays, and to eat more liquid and semi-liquid food such as millet porridge, rice porridge, soft and rotten noodles and vegetable soup. Under the guidance of the doctor, comprehensive treatment such as anti-distension, anti-diarrhea and protection of gastrointestinal mucosa should be given to avoid dehydration and electrolyte disturbance.
