A protruding upper abdomen is often due to bloating, which may be caused by trapped gas, eating habits, or digestive conditions, but other factors like fluid retention or weak abdominal muscles could also contribute.
When your upper abdomen appears to be sticking out more than usual, it is commonly because of bloating. Bloating happens when gas builds up in your stomach or intestines, making your abdomen feel full and swollen. This can occur after eating, especially if you consume foods that tend to produce gas or if you eat too quickly. Digestive disorders, like irritable bowel syndrome (IBS) or functional bloating, can also lead to recurring abdominal distension. Additionally, sometimes fluid retention (ascites) or even a weakening of your abdominal muscles might cause your upper abdomen to protrude. Although bloating is often not serious, if your symptoms are persistent, cause discomfort, or are accompanied by other symptoms such as pain or changes in bowel habits, it’s important to consult with a doctor. They can assess your condition through a physical examination and additional tests, if needed, to determine any underlying causes and suggest lifestyle adjustments or treatments to help relieve the bloating.
