Hi mani,
welcome to health care magic,
I can certainly understand your concern about your "BOOBS", which is known as "gynaecomastia" in medical terms. usually, it starts at
puberty and would reaches normal with in 2 yrs as your doctor said.
Actually, the main cause of
gynecomastia is due to the increase of oestrogen in males, due to some medications like
ketoconazole,
cimetidine etc, liver disease and Kidney Disease .In your case I would like to know if there is any such history .
Other causes could be due to the deposit of fat tissue under the chest,as you already mentioned that you exercise a lot , so this could be least possibility ,Even harmonal treatment with antiandrogens may cause this condition. so I would like to know these details to treat the cause.
If there is no such history you can try with drugs such as
tamoxifen may be helpful . The final option is surgery. you can consult your doctor and get the required suggestions
post your further questions if any, i will be always available to answer them
Thank you
