Obesity and Hair Loss
There is more and more evidence that male balding is associated with an increased risk for heart disease. Whether being overweight is associated with more severe balding is not clear.
New Study in 142 men
Researchers in Taiwan explored whether there was a relationship between body mass index (BMI) and the severity of male balding. They studied 142 men (average at 31 years) with male pattern balding who were not using medicines for hair loss. The researchers found that men with more severe hair loss tended to be more overweight than men with less severe hair loss. In fact, men who were overweight or obese had an approximately 3.5 fold greater risk for severe hair loss than men with more normal weights. In addition, young overweight or obese men had a nearly 5 fold increased risk of severe hair loss
Overall, this study support the notion that being overweight might contribute in a negative manner to balding in men. Further studies are needed to determine whether encouraging weight loss in obese patients could impact the rate of balding or the effectiveness of treatments for male balding.
