What Would Cause my Breasts to Shrink?

As a teen I was a 32B, I was athletic back then with a very low % of body fat. I am now 30 and lost appx 30 lbs in the last year. I'm nearly back at my teenage weight and now an A cup. My body fat % today is quite a bit higher now, so this doesn't make any sense to me.

Breast changes with age

Unfortunately, what you are experiencing are the normal changes that occur in the breast with age.  When you are younger, your breast has more fibrous and dense tissue.  As you age, this becomes more fatty in consistency and you start to lose some of the structural support in the breast.  Also, where your body decides it will store fat also changes with age and may not necessarily go where we want it.  The same thing goes for facial aging, where we lose volume in our face as we get older despite being the same weight.

If you are desiring fuller breasts but not necessarily implants, then you may want to consider fat grafting where you borrow fat from one part of the body where you don't want it and add it the area where you want more volume.

What would cause my breasts to shrink?

This is not uncommon. As you age your body is changing, your breasts no longer are as fibrous and dense (perky) as they were when you were a teenager.  You might consider breast implantation surgery to bring back that fullness that you lost.  This is one of the most common reasons patients do decide to undergo breast implantation surgery.  Good Luck!

Shrinking Breasts

Jumping from teen years to the age of 30 is expected to create changes in your body, especially your breasts.  It's unfortunate but one of the common reasons patients do decide to undergo breast augmentation surgery.  It may not be for you but probably is your best alternative.  Thanks for your question.

Breast size decrease

With weight fluctuations and also with aging, since the breasts are composed of a significant amount of fat, the breasts can change in size. With a relatively significant weight loss, the breasts may decrease in size, and sometimes with weight loss, some areas of the body may lose more fat than others, and unfortunately, that may be from the breasts.

Weight fluctuation can affect breast size

Breasts are made up of both glandular breast tissue and fatty deposits. The fatty part of the breast can be affected by weight loss and weight gain, just like any fat cells anywhere on the body. Unfortunately, there’s no way we can control the areas where the body chooses to store or lose fat, which means that even if your body fat percentage is higher overall than in your younger years, there’s no guarantee that the higher percentage will end up in your breasts. Your age may be playing a role in your breast appearance as well, as changing hormone levels also have a major influence.

Change in breast size and shape with aging

You are likely experiencing changes in your breasts related more to aging than weight or percent body fat. The structures and composition of the breast change with the aging process, the skin becomes less elastic and more lax, the ligaments holding the breast to the chest wall are subject to gravity and stretch out, the areola widen with weight gain, pregnancy, time and gravity. It is not simply a matter of how much you weigh and body fat. Returning your breasts to a more youthful appearance after many years and changes in your body may require the assistance of a plastic surgeon.

Breasts shrunk? Take a pill (eventually).

As others have indicated, the breast has several components : gland, fat, skin, and suspensory ligaments all of which may be changed by aging, pregnancy, hormones, weight gain, etc.  The changes you describe are the norm.  Improvements may be made with implants and/or breast lift surgery.  In the future, you may be able to take a pill that restores the tissue (via gene therapy) but at this time, surgery is your best option.  Good luck!

What would cause my breasts to shrink?

There are several factors that contribute to the reduction of breast size such as hormonal changes, pregnancies and fluctuation in weight. Keep in mind that fluctuation of your breast size due to the occurrences mentioned earlier eventually lead to the decrease of elasticity of your skin, thereby leaving your breasts to sag. I hope you found this information to be helpful.

What makes breasts become smaller?

There are 3 main components to the breast - the breast tissue itself, fat within the breast, and the skin enveloping it all. As we age and/or go through hormonal changes and or weight loss or gain, all 3 of these can change. For example, if you've aged 20 years and lost breast tissue and the skin has become more lax, but you've stayed the same weight, your breast size may appear to decrease. 

I hope this is helpful!
