Belly fat can contribute to erectile dysfunction (ED). Excess abdominal fat is associated with conditions that impair blood flow and hormone levels, such as diabetes, high blood pressure, and reduced testosterone levels. These conditions can directly impact the ability to achieve and maintain erection. What's more, the production of nitric oxide, crucial for erectile function, can be hindered by obesity. Reducing belly fat through lifestyle changes, including diet and exercise, can improve these underlying conditions and potentially reduce the symptoms of ED.
