Gynecomastia a.k.a. Man boobs is a condition that enlarges men's breasts. It can affect teenagers as well as older men. The breast tissue becomes painful and tender when a person is affected by this condition. Gynecomastia is caused due to various reasons such as hormonal imbalances, obesity, puberty, and aging. Sometimes, the condition can be caused due to side effects of medications such as anti-ulcer drugs, Klinefelter’s syndrome, illegal drugs like cannabis, drinking too much alcohol, and infections in the testicles. The treatments for the condition include surgery to remove excess tissue from the area and medications to rectify hormonal imbalances.
