Why Do Some Women Have Underdeveloped Breasts?

Written by Sarah

Why do some women have underdeveloped breasts while others do not? It’s a question that has baffled scientists and doctors for years. Unfortunately, there’s no easy answer.

Possible reasons include hormonal imbalances, genetic disorders, and even lifestyle habits. In this article, we’ll attempt to uncover the causes.

Underdeveloped Breasts – What Are the Signs?

It’s very easy for a woman to identify her own breast size. The most obvious sign of underdeveloped breasts includes a lack of fullness in the chest area.

Again, there’s no universal reason for why this is happening. It can be a combination of things as you’ll see shortly.

Possible Causes

Underdeveloped Breasts

If you are suffering from malnutrition, then this can lead to your breasts not developing as they should.

Make sure that you’re eating enough calories throughout the day (for woman it’s between 1,500 and 2,000).

Also, make sure that you’re eating a diet rich in fruits and vegetables. If your case of undeveloped breasts is being caused by malnutrition, this may be able to fix it.

It’s also possible that you have a genetic disorder that’s preventing your boobs from growing normally. Additionally, women with low body fat also tend to have smaller breasts.

If you have a very small BMI, then it isn’t too surprising that your breasts are small, too. Finally, your breast size has a lot to do with your age.

If you’re still in puberty, then there’s still time for your breasts to grow. But if you’re in your mid-20s and your breasts still aren’t growing, then that’s a problem.

The Effects of Underdeveloped Breasts


You probably don’t need us to tell you that having a small chest area can hurt your confidence and make you feel insecure.

This symptom can also affect women who are breastfeeding. They may only be able to produce a small amount of milk, so they’re forced to use baby formula.

As you can see, having underdeveloped breasts not only affects your looks, but it can also hinder your ability to breastfeed your baby. The question now becomes, is there anything that you can do about it? The short answer: yes.

Are Implants The Way to Go?

We don’t recommend getting breast implants for increasing your bust size. The first reason why is because they are very expensive (think several thousand dollars).

Also, you don’t want to be put under general anesthesia unless there’s a serious reason to do so.

Getting bigger breasts is important, but not important enough to risk your life. The better alternative would be to learn how to increase the size of your breasts naturally.

Increasing Bust Size Naturally

The first thing you can try are exercises that target your pectoral muscles. These include exercises like pushups, wall presses, and bench presses.

By targeting this muscle group, you’ll help your breasts appear fuller. You can also change your diet, which may help.

Start eating more legumes, soymilk, and soybeans as these have been scientifically proven to help women with underdeveloped breasts.

Finally, if you’re really desperate, give BustMaxx a try. It’s composed of all-natural ingredients that can make breast enlargement way easier.
