Steroid Injection Fat Loss Under the Skin – Understanding the Risks and Why Seeing a Doctor Matters

Steroid injections are sometimes used to help treat inflammation, allergies, joint pain, arthritis, and severe hayfever symptoms. For many people, they can provide significant relief. However, like all medical treatments, steroid injections can occasionally cause side effects.

One lesser-known side effect is called lipoatrophy – a small dent or hollow that can appear under the skin where the injection was given.

At OneMedicine Private GP Clinic Birmingham, we believe patients should understand both the benefits and risks of any treatment before deciding whether it is right for them.

What Is Lipoatrophy?

Lipoatrophy means a loss of fat underneath the skin.

After a steroid injection, some people may notice:

• A small dent or dip in the skin
• A hollow or indentation at the injection site
• Skin that appears thinner than before

This change usually develops gradually over several weeks or months after the injection rather than immediately.

Why Can Steroid Injections Cause This?

Doctors believe steroid medication can sometimes affect the fat tissue underneath the skin.

This may happen because the steroid:

• Stays in the area for a long time
• Reduces blood supply locally
• Affects collagen and soft tissue healing
• Irritates or damages nearby fat tissue

The risk may be higher if the injection is placed too close to the skin surface rather than deeper into the muscle.

Are Hayfever Steroid Injections Included?

Yes. Some steroid injections used for severe hayfever symptoms may carry this risk, particularly intramuscular steroid injections.

Although many patients have steroid injections without complications, lipoatrophy is a recognised possible side effect and should be discussed before treatment.

What Does It Look Like?

People often describe:

• A “dimple” under the skin
• A visible dent
• A small sunken area
• Skin thinning or lighter skin colour

Most cases are painless, but the cosmetic appearance can understandably be upsetting for some patients.

Does It Go Away?

Sometimes the area improves on its own over time, but this can take months.

In some cases, the change may last longer or require treatment. Treatments reported in medical literature include:

• Monitoring and observation
• Saline injections
• Fat grafting or cosmetic procedures in severe cases

Why Seeing a Doctor Matters

Steroid injections may seem simple, but proper assessment and injection technique are important in helping reduce risks.

A doctor can help ensure:

• A steroid injection is actually appropriate for your condition
• Other safer treatments have been considered first
• The correct medication and dose are used
• The injection is given in the correct place and at the correct depth
• Potential risks and side effects are properly explained

Incorrect injection technique or placing steroid too close to the skin may increase the risk of lipoatrophy and other complications.

Doctor-led assessment is especially important for people with:

• Diabetes
• Immune system problems
• Skin conditions
• Previous steroid injection complications
• Complex medical histories

At OneMedicine Birmingham Private GP Clinic, all steroid injection assessments are carried out in a doctor-led clinical setting with focus on patient safety, informed consent, and appropriate follow-up care.

When Should You Seek Medical Advice?

You should seek medical assessment if you develop:

• A new dent or hollow after an injection
• Pain, redness, or swelling
• Skin colour changes
• A worsening appearance over time
• Concerns about infection or scarring

A doctor can assess whether the area represents lipoatrophy or another condition requiring treatment.

Final Thoughts

Steroid injections can be effective treatments for some conditions, including severe inflammation and hayfever symptoms. However, they are not risk-free.

Lipoatrophy is an uncommon but recognised side effect that can appear weeks or months after treatment. Choosing a qualified doctor for assessment and injection technique may help reduce the risk of complications.
