Is it possible to have unilateral gynecomastia?

I have been worried over the past years that I may have developed gynecomastia. The odd thing is that it only seems to be in my left nipple. Is it possible to have unilateral gynecomastia? How common is it and can I have surgery done on only one nipple and it come out looking normal?

About a year ago, I had surgery for exactly what you have described, unilateral gynecomastia. It's not as common as bilateral, but yes, it is possible. I had been a heavy drinker and overweight for years, and I guess it finally caught up with me. Weight loss and drinking less only seemed to make it worse, since then I was left with excess skin and the asymmetry between my nipples drove me nuts. Surgery to fix the asymmetry is definitely more expensive and there are some risks involved (excessive bleeding, for example), but now you really can't tell the difference between either of my nipples. They look the same to me, and it's great!

The simple answer to both questions is YES!  So go on some complimentary consultations with experts and compare recommendations and look at photos of similar patients and find your surgeon

The answer to this question is yes, it is absolutely possible to have unilateral gynecomastia. Most people, including myself, think that whatever happens to one breast has to happen to the other one. So I was extremely confused when only one of my breasts began to change in size and shape and the other one remained perfectly normal. I was told that unilateral gynecomastia is actually quite common. I stopped worrying when I heard that I was certainly not the only one who suffered from this. You can treat gynecomastia with surgery.

Unilateral gynecomastia often occurs in prepubertal boys. An imbalance in your testosterone levels can cause gynecomastia so it makes sense that when you are going through puberty you can see some abnormal breast enlargement. I thought that there was something wrong since only my right breast was affected. I was actually scared to ask a doctor about it for fear of the answer that I would get. Fortunately, I found that this is a very common condition, and does not have to be a cause for concern. After puberty, my "male breasts" began to go back to normal as the condition resolved itself.

I have some sort of abnormality with my right nipple and not my left. I did go through a phase of way too much extra curricular drug activity that could have had an effect on my body. I was running anabolic steroids and smoking marijuana at night to calm my nerves from heavy lifts. I had heard of risks of "gyno" before when dealing with steroids because your estrogen levels could be increased causing a sex hormone imbalance. Even though I knew these risks I didn't really feel I would be affected by it. But I was! The last straw was when I noticed some nipple discharge - aside from being disgusting I figured I should go to the doctor for a physical examination. I was diagnosed with unilateral gynecomastia and I am planning to have the surgery soon.

When I started showing symptoms of gynecomastia, one of my breast was bigger than the other. While I thought this was common, the one breast kept increasing in size and changing shape so I went to see my doctor. I also noticed that a difference in the nipples and skin around the breast tissue. Gynecomastia can affect one or both breasts. When bilateral or unilateral occurs in a young boy, in many cases the breasts shrink after puberty. One of the causes of unilateral breast growth is asymmetrical rib cage. For both unilateral and bilateral gynecomastia both breasts will be examined by a doctor who will then decide whether it’s ideal to operate just one breast or both. This is important because while one of my breast was reduced, it later turned out that the other breast needed surgery too.
