If you have recently lost weight or are in the process of losing weight, your breast shape and size might also be affected. This is completely normal, as weight loss affects your entire body. Keep reading below where we go through how weight loss can affect your breast size and shape.

Breasts: A Composition of Tissues

Breasts are made up of a variety of different breast tissue, including glandular tissue, fibrous tissue, and fatty tissue, which is the main tissue that determines your breast size. Since the majority of breast tissue is made up of fatty tissue, it is subject to the bodily changes that come with weight loss.

If I Lose Weight Will My Breasts Get Smaller?

If you are losing weight, your breast tissue can shrink along with you. Since breasts are made up of fatty tissue, you may find that your breast size decreases as your body weight decreases.

If you have lost weight rapidly, depending on how much weight you have lost, you might find that your breasts have a deflated appearance or that your breasts sag more than they used to. Sagging breasts can be a result of rapid weight loss and this is a completely normal occurrence.

If you find yourself with sagging breasts after losing weight and are unhappy with the appearance, you can look into a breast augmentation surgical procedure to restore volume and shape to your breasts.

Beyond Weight Loss: Other Factors Affecting Breasts

If you lose weight, chances are that your breast size has also shrunken. But there are many other factors that can affect breast size and shape.

Women's bodies go through many different stages throughout life, all of which can impact your breasts. Various hormonal changes throughout life, like puberty, pregnancy, and menopause can all affect your breasts.

If you have been pregnant and have breastfed, chances are your breasts are no longer as voluminous or perky as they used to be. Even menstruation can affect your breast size month to month.
