There are many reasons why your body feels hungry, but you are still nauseous after eating. If you are a woman of childbearing age and have a history of sex without contraception, it may be due to pregnancy. However, very hungry eating and still nausea may also be related to improper diet, gastritis and certain intestinal diseases, which are seen in all people at this time. 1, pregnancy: after pregnancy, due to a large increase in hormone levels in the female body, as well as the growing uterus, pressure on the stomach and intestines, resulting in a decline in gastrointestinal function, and thus the symptoms of very hungry but nauseous eating. This situation is a normal physiological reaction, no special treatment; 2, improper diet: such as unclean diet or eating greasy, spicy and irritating food, may lead to very hungry but eating nausea. In this case, attention should be paid to changing dietary habits, avoid eating unclean and irritating food, if necessary, under the guidance of a doctor to take the stomach and eliminate food tablets or probiotics tablets for treatment; 3, gastritis: inflammatory stimulation of the gastric mucosa, which can appear hungry but eating nausea. Treatment should pay attention to avoid eating too hard, too acidic, too hot, too spicy food, abstain from alcohol, avoid drinking strong tea, coffee, etc., and eat less high-salt, processed as well as smoked and pickled food. Drugs that inhibit gastric acid secretion, protect the gastric mucosa and promote gastrointestinal motility, such as cimetidine, omeprazole and domperidone, can also be used under the guidance of a doctor. In the case of gastritis with H. pylori infection, treatment with H. pylori quadruple therapy is required; 4. Intestinal diseases: such as enteritis, food stimulates the gastrointestinal tract after eating, causing increased peristalsis of the colon, which in turn leads to a very hungry but nauseous eating situation.

If the symptoms are caused by an occupying lesion in the intestine, it is necessary to go to the hospital in a timely manner to clarify the location of the lesion, and if necessary, surgery is needed to remove the lesion.
