why do i get nauseous when i eat

Nausea after eating can be caused by various factors related to the digestive system or other health conditions. Common reasons include overeating, eating fatty or spicy foods which are hard to digest, food intolerances or allergies (e.g., lactose intolerance), infections like gastroenteritis, food poisoning, gastrointestinal disorders such as gastroesophageal reflux disease (GERD), gallbladder problems, pancreatitis, and irritable bowel syndrome (IBS). Psychological factors like stress or anxiety can also contribute to nausea after meals. In some cases, nausea after eating may indicate a more serious condition such as chronic mesenteric ischemia or digestive cancers, but usually, it is linked to digestive disturbances or food-related issues. If nausea persists or is severe, consulting a healthcare professional for diagnosis and treatment is advisable.
