What other treatment options for gynecomastia?

Surgery and surgery!: Other than weight loss (and treatment of any stimulating causes, like testicular tumors or other hormone causes), surgery is the only way to remove gynecomastia tissues, especially glandular component. Liposuction can help with the fatty part, but excision is needed for the glandular portion. There is no diet or supplement that can help. See an abps-certified plastic surgeon.

Only two: In adults, weight loss if it is fatty, surgery if it is glandular.

Liposuction: Sometimes liposuction can be useful for a male of normal weight who has minimal glandular hypertrophy with an excess of fatty tissue in the breast. Combining liposuction with excisional surgery may also be an option.
