GLP-1: Weight Loss and Its Impact on Breasts | Glamorise

If you have recently lost weight — even small fluctuations of 5-10 pounds — your breast size and shape may have also changed. Breasts are composed primarily of fatty tissue, which means they are susceptible to size and shape changes during weight loss.

Making sure you are wearing the correct bra size and style for your body is key, especially after weight loss. Let’s go through what you need to know about how losing weight can affect breasts, and what we recommend to do to find your perfect bra fit.

Weight Loss and Impact on Breasts

Weight loss drugs such as GLP-1 have had a rapid increase in popularity in the last few years. GLP-1 drugs are FDA-approved to encourage weight loss and for chronic weight management in adults with obesity and high body mass index.1

Some women taking these drugs have also noted that their breasts have changed size and shape.2 This is to be expected when undergoing any weight loss, but losing weight rapidly can have a stark effect on breasts, which some women may not expect.

Bra Size Changes

Both your bra band size and cup size may change after losing weight, so it's important to re-measure your size to ensure your bras are a good fit. If your bra doesn't fit well, it likely won't provide the support you need.

Having a bra that fits well is crucial to getting the support you need. If you have undergone significant weight loss, take your band and bust measurements again and plug them into our Bra Size Calculator to find your perfect fit.

Finding the Right Bra Style After Using GLP-1

After considerable weight loss, you may find that your breast size and shape is much different than before. If your breast shape has changed after taking weight loss drugs, the bra style that you usually wear may no longer be a great fit.

We recommend trying out a wide array of bra styles to see what works best for your body. Your bra needs may have changed, or maybe you have different preferences now. Maybe you’ve been a lifelong wireless bra wearer, but now an underwire bra provides better lift and support for you.

Final Thoughts

Always consult a doctor to determine the best weight loss options for you. If you choose to use GLP-1 weight loss drugs, your breast size and shape may also change. After weight loss, be sure to measure your bra size regularly and try out an array of bra styles to see what works best for you.
