What is Ozempic butt?

Ozempic butt is a non-medical term used to describe changes in the appearance of the buttocks that some people notice while losing weight on GLP-1 medications such as Ozempic. It usually refers to reduced volume, flattening, or a looser appearance linked to fat loss rather than injury or disease.

In this guide, we’ll explore what "Ozempic butt" means, why it happens, who is more likely to experience it and what steps can be taken to manage it.

What does “Ozempic butt” mean?

The term “Ozempic butt” refers to changes in the shape around the buttocks that some people experience while using GLP-1 medications like Ozempic, Wegovy, or Mounjaro.

Typically, this involves a loss of volume in the buttocks, leading to a sagging or flattened appearance. It's important to note that this can occur with any rapid weight loss, not just with Ozempic.

Why does Ozempic butt happen?

One side effect of Ozempic (and other medications like Wegovy that contain semaglutide, the same active ingredient) is that they work by reducing appetite and promoting feelings of fullness. This can lead to significant weight loss.

This rapid weight loss can affect the body’s fat distribution. The buttocks, like other areas of the body, may lose subcutaneous fat. The result may be a reduction in volume, leading to what is being anecdotal referred to as "Ozempic butt."

In some cases, if a person's diet lacks sufficient protein or if resistance exercise is minimal, muscle loss may also contribute to this appearance.

Is Ozempic butt a side effect of Ozempic?

Ozempic butt is not officially listed as a medical side effect of the medication. Medical side effects typically involve issues like nausea, dizziness, or digestive disturbances, whereas changes in body shape are a result of fat loss. It’s a natural change as a result of weight loss, rather than an adverse reaction to the medication.

Who is more likely to experience Ozempic butt?

People who experience rapid or significant weight loss are more likely to notice changes in their body shape. Several factors can contribute to the likelihood of developing Ozempic butt, including:

  • age
  • starting weight
  • genetics
  • muscle mass
  • skin elasticity

Older people or those with less muscle mass may be more likely to notice this change.

Is Ozempic butt permanent?

For most people, any changes to the buttocks that occur during rapid weight loss can improve over time. Once weight stabilises, the body may begin to rebuild muscle, and skin may tighten, improving the appearance of the buttocks.

However, these changes vary from person to person and may not be fully reversible for everyone.

Can Ozempic butt be prevented?

While it may not be entirely preventable, there are steps that you can take to reduce the severity of Ozempic butt:

  • maintain muscle mass through regular strength training
  • ensure adequate protein intake to support muscle maintenance
  • focus on gradual weight loss to help the skin and muscles adapt more effectively

➤ The NHS recommends losing around 1 to 2 lbs per week.

How to improve the appearance of Ozempic butt

If you would like to improve the appearance of your buttocks, there are several lifestyle changes that may help.

Build and maintain muscle

Resistance training, and particularly exercises that target the glute muscles, can help preserve and even increase muscle tone in the buttocks, which may help combat the appearance of sagging. You may wish to try exercises like:

✓ squats

✓ glute bridges

✓ deadlifts

✓ lunges

✓ clamshell exercises

Discover how much exercise you generally need to do to lose weight.

Protein intake and nutrition

Adequate protein is essential for maintaining muscle mass during weight loss. Eating a well-balanced diet that supports muscle retention can help mitigate the effects of fat loss on the body.

Good sources of protein include:

✓ lean meats and fish

✓ eggs

✓ beans, lentils and chickpeas

✓ tofu

Skin health and elasticity

Ageing, genetics, and hydration play a key role in skin elasticity. While there is limited evidence that supplements or topical products can prevent skin sagging, staying hydrated and supporting overall skin health through good nutrition may help improve skin appearance.

Does Ozempic butt mean the medication is not right for me?

The appearance of Ozempic butt does not necessarily mean that the medication is unsuitable for you. While changes in body shape are a common response to weight loss, they do not indicate a problem with the medication itself.

If the rate of weight loss or body shape changes feels concerning, it’s important to discuss this with a doctor to ensure the treatment is working as expected.

When to speak to a doctor

If the physical changes you're experiencing, such as the appearance of Ozempic butt, are affecting your quality of life or if you have any concerns, it's always a good idea to speak to your doctor.

If you feel that weight loss is happening too quickly or is causing distress, talk about this with your doctor.

Summary: Ozempic butt

Ozempic butt is a common, non-dangerous effect that some users of Ozempic and other medications like Wegovy experience due to rapid weight loss. With gradual weight loss, strength training, and time, the appearance of the buttocks often improves. Ensuring muscle maintenance, proper nutrition, and good skin care can help minimise its impact.

If you are currently taking weight loss treatment through ZAVA and are concerned about Ozempic butt then you can speak with one of our doctors.

Frequently asked questions

Is Ozempic butt a real side effect?

Ozempic butt is not a listed medical side effect of Ozempic or other GLP-1 medications. The term describes physical changes caused by weight loss itself, not a direct effect of the medication on muscle or skin.

Does everyone get Ozempic butt?

Not everyone who takes Ozempic experiences Ozempic butt. The likelihood depends on factors such as how quickly you lose weight, your starting body composition, muscle mass, and skin elasticity.

Does Ozempic butt mean I am losing weight too fast?

Not necessarily. Ozempic butt can be more noticeable with rapid weight loss, but it does not automatically mean weight loss is unsafe. If changes feel sudden or concerning, it is reasonable to discuss pace and support options with a doctor.

Can exercise help with Ozempic butt?

Strength training can help improve muscle tone in the buttocks, which may improve appearance over time. Exercise cannot restore lost fat, but it can support muscle shape and overall body composition.
