<s>[INST] Can obesity be the reason for severe gynecomastia? If yes, what are the cures, exercises, and medicines for it or is surgery the only option for gynecomastia? [/INST] When breast tissue in males swells due to hormone imbalance, it is called Gynaecomastia. The male hormone ie., the testosterone levels decrease and/or the female hormone ie., oestrogen levels increase. Obesity leads to reduction in the male hormones in male thereby giving rise to gyneacomasita. A significant weight loss needs to occur in order to bring about a reversal of the female hormone to male hormone. Exercises, Medicines rarely cure or completely treat the hormonal change. In order for the root cause to be treated the person needs to treat obesity completely so that hormonal change and gyneacomastia are both treated. Metabolic and Baraitric surgery is once such treatment that can cure both gyneacomastia and obesity. Just Surgical treatment of gyneacomastia can be done only in patients who are not over-weight or obese and those who's hormonal levels are normal. Source: LOC. Link: https://obesityasia.com/faqs/.
