In summer, the body’s immune function is in a relatively “weak” state, which is related to the high temperature, decreased appetite, insufficient intake of nutrients. Patients with liver disease should pay attention to the following aspects in summer: 1, avoid overwork, maintain sufficient sleep. Exhaustion will destroy the body’s immune balance, aggravate the burden on the liver, and easily lead to the recurrence of chronic hepatitis. 2, pay attention to dietary balance: hepatitis patients should not overeat in summer, the diet should be light, nutritious food, eat more fresh and digestible food, avoid eating greasy, fried, spicy food. Ensure the nutritional matching of three meals. May be appropriate to choose to eat “food cold” food, such as cucumber, winter melon, bitter melon, bean sprouts, watermelon and so on. 3, do not drink alcohol: more alcohol will hurt the liver, including beer. 4, summer heat and humidity, mosquitoes and flies, viruses and bacteria are easy to enter the body with unclean food, resulting in infection. Liver disease patients should prevent the disease from entering by mouth. In summer, we should eat less raw food, avoid eating raw vegetables, fish or seafood, so as not to let the hepatitis virus have the opportunity to take advantage of, resulting in the occurrence of hepatitis. 5, pay attention to personal hygiene, wash hands before and after meals, do not drink raw water.
