Why Do I Feel Full After Eating Very Little? Causes and When to Worry

Quick Answer

Feeling full after eating very little, known as early satiety, is a sensation of fullness that occurs unusually quickly during a meal, preventing you from finishing a normal-sized portion. It can be a symptom of various underlying conditions, ranging from common digestive issues like indigestion or GERD to more serious problems such as gastroparesis or, in rare cases, certain cancers. Persistent early satiety warrants medical evaluation to determine the cause and appropriate treatment.
