Weight gain is the most common reason why men grow boobs. But it is not just because of the increased fat; there is also a hormonal link. Being overweight may increase a man’s levels of oestrogen, which can cause breast tissue to grow, noted the UK health website NHS.com.
Males of any age can develop man boobs, even newborns, according to the SGH website. Male babies may have high oestrogen levels at birth as the hormone passes through the placenta from their mothers to them. However, this is temporary and will disappear a few weeks after the baby’s delivery, noted the website.
By and large, the majority of patients tend to be boys “at about 18 to 21 years old” and “almost all are puberty and obesity related,” said Professor Lee Kok Onn, senior consultant at NUH’s Division of Endocrinology. Dr Mok added that these adolescents usually resolve spontaneously within six to 12 months on their own after the hormonal levels stabilise.
