Women's Health care Abdominal distension refers to a visibly swollen or enlarged abdomen that appears larger than normal. It may occur due to gas buildup, constipation, pregnancy, fluid accumulation, weight gain, digestive disorders, or underlying medical conditions. While occasional abdominal distension is often related to digestion and bloating, persistent or worsening abdominal swelling may indicate a more serious health issue that requires medical evaluation.
