Big breasts, small breasts, medium sized breasts; all women’s breasts are unique one way or the other. No one has the exact same identical pair. One side may be smaller, saggier, or bigger. So what determines breast shape or size? Our mothers? Our diet?
Here are some known determinants of breast size;
Far and away, genetics plays the biggest role in the size and shape of your breasts. Your genes also influence the levels of your hormones, which affect your breast tissue. Genes determine how dense your breasts are, as well as what your skin is like, which affects the appearance of your breasts. Your breast characteristics can come from both sides of your family, so genes from your dad’s side can affect what your breasts end up looking like too.
No matter how big or small your breasts are to begin with, a large proportion of the tissue is made up of fat. So it’s no coincidence that your breasts expand when you do. Similarly, as you lose weight, your breast size could change too. How much fat you lose in your breasts when you drop weight may depend, in part, on the composition of your breasts. Women with dense breast tissue tend to have more tissue and less fatty tissue.
If that’s you, when you lose weight, you may not notice as significant of a decrease in your breasts as a woman who has a greater proportion of fatty tissue in her breasts to begin with. You can’t feel whether you have dense or fatty breasts (only a mammogram or other imaging would show this), so you may not know which category your breasts fall into. And as for those tiny women with big breasts? It’s all thanks to genetics.
Enjoy your firm breasts while you can. Like everything else, gravity takes its toll on the breasts. Beneath the surface, your Cooper’s ligaments, delicate bands of tissue, help hold everything up. They’re not true ligaments like those that hold muscle to bone, they’re fibrous structures in the breast.
Over time, they can wear out like overstretched rubber bands and become less supportive, eventually causing sagging and drooping. The good news is that you can fight back by regularly sporting well-fitting supportive bras in order to reduce the gravitational pull on your Cooper’s ligaments. Find the best bra for your breast type.
It’s the blessing and the curse of pregnancy: Your breasts swell to huge size while pregnant and nursing, but deflate like a balloon when you wean. It’s not entirely understood why they change so dramatically, but it may be due to fluctuations in hormones and the fact that the skin stretches as the breasts become engorged and may not fully contract to their pre-baby firmness after nursing.
You can do all the chest exercises, but they’re unlikely to have any noticeable impact on the appearance of your breasts. Your breasts sit on top of the pectoral muscles, but aren’t part of them so you can develop stronger muscles underneath your breasts without changing their size or shape.
There are, however, a few exceptions. Body-builders and women who participate in fitness competitions often have such low body fat that their breasts appear firmer. There’s some data demonstrating that breast size and density also changes in women who do a significant amount of aerobic activity. This is probably due to the fact that you lose body fat, but your breast tissue components don’t change so you develop denser breasts when you exercise more.
So there you have it ladies! If you’re wondering why your breasts are the way they are, your answers lie in this article.
