Hunger pangs are associated with chronic peptic ulcers, hypoglycemia, pregnancy and other factors. Whenever the human body is hungry, there is usually no desire to vomit. Whenever there is a desire to vomit when hungry, it is considered to be caused by chronic digestive system diseases, such as duodenal ulcer, gastric ulcer, chronic gastritis and other diseases. When there is no food in the stomach during hunger, there will be more gastric acid secretion, which will cause nausea and vomiting when the gastric mucosa is stimulated. Patients with hypoglycemia will signal hunger when they are hungry, and if there is no food intake, it may cause a feeling of vertigo with nausea and vomiting. Many people are prone to nervousness and stress during pregnancy, and due to the increase in hormone levels, they will also have a series of early pregnancy reactions, such as stomach pain, nausea, vomiting and other digestive system symptoms when they are hungry.
