What Are the Common Causes of a Persistent Feeling of Fullness in the Stomach?

When you feel full for a long time, several things might be happening in your stomach. One reason is that your stomach may be emptying slowly. This means that food stays in your stomach longer than it should—a condition sometimes called gastroparesis. Another common cause is functional dyspepsia. This is when your stomach feels full or uncomfortable even though there is no clear blockage or disease. Gas and bloating may also contribute to the constant feeling of fullness. Foods that are hard to digest or create extra gas, such as those high in fat, may make your stomach feel stretched. Overeating or eating quickly can add to this feeling too. In some cases, changes in the bacteria in your gut or issues like small intestinal bacterial overgrowth can cause extra gas or bloating. These conditions can lead to a persistent sensation of fullness that may be uncomfortable. It’s important to know that addressing the underlying reason, through dietary changes or medical treatment, can often help relieve these symptoms.
