Obesity is a medical condition characterized by excessive body fat that negatively affects health. It’s typically measured using the body mass index (BMI), waist circumference, and body composition. When excess weight accumulates—especially around the abdomen—it increases the risk of numerous health problems, including cardiovascular disease, diabetes, and hormonal imbalances. Erectile dysfunction (ED) is the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. While ED has multiple causes—vascular, hormonal, neurological, and psychological—obesity plays a significant and direct role in increasing ED risk. In Riyadh, where urban lifestyles, diet changes, and reduced physical activity contribute to rising rates of overweight and obesity, this connection is especially important for men’s health.
