The desire to eat all the time is associated with diseases such as hyperstomach fire, stomach ulcers, and partly caused by diabetes and hyperthyroidism. A person with hyperactive stomach fire will have a strong appetite, and after eating food, the food will be emptied quickly. Therefore it will be accompanied by a feeling of hunger and will always want to eat, which can be treated with stomach-clearing medicine. Some people have gastric ulcer disease, which is characterized by excessive secretion of gastric acid. Excessive gastric acid causes rapid digestion of food and induces pain when the gastric acid stimulates the ulcer surface, and many people will mistake this for hunger and therefore always want to eat. Diabetes and hyperthyroidism are hypercalcemic adenomyosis. Patients with the disease will be more hyperactive physically and will not only show symptoms of excessive food and easy hunger, but will also be accompanied by weight loss and irritability, etc. Blood tests and thyroid function tests are needed to confirm this.
