Abdominal distension refers to the noticeable swelling or enlargement of the abdomen. This condition can occur due to various factors, including the accumulation of gas, fluid, or solid material in the digestive tract. Common causes include overeating, constipation, and certain medical conditions like irritable bowel syndrome or ascites. Symptoms of abdominal distension may include a feeling of fullness, discomfort, or pain in the abdomen. It can also lead to visible bloating. Treatment often focuses on addressing the underlying cause, which may involve dietary changes, medications, or other medical interventions as needed.
