Frequent skipping meals may cause digestive system diseases, anemia, malnutrition, hypoglycemia and other consequences. 1. Digestive system diseases: if patients often do not eat, in the case of excessive fasting, the stomach wall cells will secrete a large amount of gastric acid, but can not be neutralized by food, which will stimulate the gastric mucosa for a long time, leading to digestive system diseases, such as gastritis, gastric ulcers, duodenal ulcers and so on. 2. Anemia, malnutrition: because the human intestines can not absorb enough nutrients, the basic metabolism of the human body will be reduced, patients often do not eat may also lead to anemia, malnutrition diseases. 3. Hypoglycemia: Normally, the human body has a normal metabolism and needs sugar to be converted into energy. If patients often do not eat may lead to excessive consumption of glycogen and symptoms of hypoglycemia, such as dizziness, cold sweats and so on. To develop a healthy body, we need to eat reasonably, eat regularly on time, and pay attention to normal eating intake of various nutrients.
