The desire to vomit and hunger is related to gallbladder disease, stomach cancer and other factors, some people are caused by pregnancy. The gallbladder has the function of storing bile, and once the bile is not discharged smoothly, it will lead to gallbladder diseases, such as gallstones and cholecystitis. When gallbladder disease occurs, it not only causes abdominal pain, but also stimulates the stomach, causing the peristaltic function of the stomach to be affected, so nausea and vomiting will occur. Stomach cancer is a serious disease and causes various symptoms. When stomach cancer enters advanced stage, patients will not only have impaired gastric motility, but also experience nausea and vomiting due to the stimulation caused by cancer cells. Stomach cancer will consume a lot of energy, so many patients will feel hungry. Some women may experience nausea and vomiting during pregnancy due to hormonal stimulation of the gastrointestinal system, and many pregnant women may also experience hunger during pregnancy due to the large amount of capacity needed for fetal development.
