Bubble gut, also known as “distended abdomen” or “GH gut,” refers to an unusually protruding stomach mainly seen in bodybuilders. It’s tied to several extreme practices, including the excessive use of insulin and human growth hormone (HGH), leading to organ growth and intestinal hypertrophy. High-calorie diets, necessary for mass gain, can cause bloating, while anabolic steroids contribute to fluid retention, worsening the condition. Intense abdominal workouts further expand the abdominal cavity. Thus, bubble gut arises from a mix of chemical, dietary, and training practices.
