Frequent feeling of hunger is usually not a manifestation of pre-stomach cancer. Usually, the symptoms of pre-stomach cancer are few and atypical. Some patients may experience symptoms such as abdominal distension, abdominal pain, nausea, vomiting, lack of appetite, or even blood in stool. There are many causes of hunger, which may be caused by other diseases, excluding the factor of insufficient food intake. Patients with gastritis or gastric ulcer will have abdominal pain due to damage to their gastric mucosa, but the visceral nerves are poorly fixed for nociceptive function, and some patients will show hunger-like pain. Patients with hyperthyroidism have an increased basal metabolic rate of the organism and often show hunger, excessive sweating, lethargy and fear of heat. Patients with diabetes have typical manifestations of three more and one less, i.e., drinking more, eating more, urinating more, and losing weight, and often experience hunger due to impaired glucose metabolism. Therefore, it is important to go to the gastroenterology or endocrinology department for corresponding examination in time when hunger often appears, and carry out symptomatic treatment after clear diagnosis in order to recover health as soon as possible. If patients often experience hunger, they should pay attention to eating light and easily digestible food, avoiding spicy and stimulating food and food that produces a lot of gas.
