Bubble stomach in bodybuilding, also known as “HGH Belly,” is a term used to describe the bloated and distended midsections seen in some professional bodybuilders. Despite having chiseled physiques and low body fat, these athletes display prominently protruding abdomens, which has raised curiosity and concern within the bodybuilding community and among fans. This phenomenon has been observed in some of the top competitors, including renowned champions like Phil Heath, Kai Greene, and Ronnie Coleman.
In this blog, we’ll delve into what bubble stomach is, why it occurs, and how it might be prevented.
What is a Bubble Stomach?
Bubble stomach refers to the abnormal distention of the abdomen in bodybuilders, creating a rounded and bloated appearance. This condition is especially noticeable when bodybuilders are on stage, posing and flexing their muscles. Unlike the lean and flat midsections typically expected of elite athletes, bubble stomach gives the impression of a heavily bloated belly, almost as if the bodybuilder is in the early stages of pregnancy.
Causes of Bubble Stomach
Below are some of the causes of bubble stomach
1. Human Growth Hormone (HGH) and Insulin Usage
One of the primary factors contributing to bubble stomach is the use of Human Growth Hormone (HGH) and insulin. These substances are used by bodybuilders to enhance muscle growth and increase overall body mass. However, their side effects include significant water retention and increased organ size, particularly in the abdominal region. Dr. Thomas O’Connor, also known as the “Anabolic Doc,” suggests that while steroids alone did not cause bubble stomachs in the past, the combination of HGH and insulin has contributed significantly to this condition in modern bodybuilding.
2. High-Calorie, High-Carbohydrate Diets
Professional bodybuilders consume enormous amounts of calories and carbohydrates to fuel their intense training regimens and muscle growth. Diets consisting of up to 10,000 calories per day and 1,000 grams of carbohydrates are not uncommon. Such high-calorie and high-carb intake can lead to gastrointestinal bloating and water retention, further exacerbating the appearance of a distended abdomen.
3. Growth of Mesentery and Abdominal Muscles
HGH is known to stimulate the growth of various tissues in the body, including the mesentery (a fold of tissue that attaches the intestines to the abdominal wall) and abdominal muscles. This tissue growth contributes to the outward expansion of the abdomen, making the midsection appear more bloated.
4. Genetic Factors
Genetics play a crucial role in how an individual’s body responds to various stimuli, including drug use and dietary habits. Some bodybuilders may be more genetically predisposed to developing bubble stomach due to how their bodies process and store nutrients and how their tissues grow in response to HGH and insulin.
5. Water Retention
The high carbohydrate intake common in bodybuilding diets can lead to significant water retention. Carbohydrates are stored in the muscles and liver as glycogen, and each gram of glycogen is bound to several grams of water. This water retention can cause a swollen and bloated appearance in the abdominal region.
Prevention and Management of Bubble Stomach

While HGH is often blamed for the bubble stomach phenomenon, it is not the sole cause. Former Mr. Olympia Dorian Yates, in an interview with Joe Rogan, stated that despite using HGH, his internal organ size remained normal, suggesting that other factors are at play. Dr. O’Connor emphasizes that the condition is multi-factorial, involving genetics, high-calorie diets, and the combined use of HGH and insulin.
1. Tapering Down Drug Use
One of the primary strategies to prevent bubble stomach is to moderate the use of HGH and insulin. Reducing the dosages of these substances, especially in the weeks leading up to a competition, can help minimize the bloating and abdominal distention.
2. Dietary Adjustments
Adjusting the diet to reduce carbohydrate intake and overall calories can help control water retention and gastrointestinal bloating. Bodybuilders may focus on cleaner, less voluminous foods that provide the necessary nutrients without excessive bulk.
3. Emphasis on Aesthetic Physiques
The bodybuilding community is beginning to place more emphasis on aesthetic physiques rather than sheer size. Competitors like Shawn Rhoden, who won the Mr. Olympia title with a tighter and more aesthetically pleasing midsection, represent a shift towards rewarding balanced and proportionate physiques. This shift may encourage athletes to prioritize aesthetics over extreme muscle mass and, consequently, reduce the occurrence of bubble stomach.
4. Genetic Screening and Personalized Training
Understanding an individual’s genetic predispositions can help tailor their training and dietary plans to minimize adverse effects. Personalized approaches can optimize muscle growth while mitigating the risks of developing a bubble stomach.
Conclusion
Bubble stomach is a complex and multifaceted issue in bodybuilding, influenced by the use of performance-enhancing drugs like HGH and insulin, high-calorie and high-carbohydrate diets, genetic factors, and water retention. While it presents a significant aesthetic concern, understanding its causes and implementing preventive measures can help bodybuilders achieve a more balanced and aesthetically pleasing physique.
As the bodybuilding community continues to evolve, a renewed focus on proportionate and tight midsections may help mitigate the prevalence of bubble stomach, ensuring that the sport maintains its visual appeal and integrity
