GLP-1 Medications & Psoriasis: What You Should Know

If you’re managing psoriasis alongside obesity or type 2 diabetes, you already know how much these conditions can influence each other. A difficult stretch with your skin can affect your energy, your confidence, and your overall health — and managing two chronic conditions at once takes real effort.

Here’s something that may be encouraging: medications originally developed for metabolic conditions are showing real promise for people with psoriasis. This guide explains what we currently know, what it might mean for you, and how to have an informed conversation with your care team.

The Connection Between Metabolic Health and Psoriasis

For a long time, doctors viewed obesity as something that simply tended to occur alongside psoriasis. Now we understand the relationship runs much deeper.

Excess body fat doesn't just sit passively in the body — it actively produces inflammatory signals. These signals add to the same type of body-wide inflammation that drives psoriasis flares. At the same time, severe psoriasis can affect the way your body processes insulin, which may raise your risk for metabolic conditions like type 2 diabetes.

In other words, the two conditions can fuel each other. That's why treating the whole picture — not just the skin — can make such a meaningful difference.

How GLP-1 Medications May Help

GLP-1 medications are a class of medications that work by mimicking a natural hormone in the body. They're widely used to treat type 2 diabetes and obesity by helping regulate blood sugar and appetite. But researchers and dermatologists have started noticing something interesting: many people on these medications also see their psoriasis improve. There appear to be two reasons for this.

1. Less Body Fat, Less Inflammation

GLP-1 medications help many people lose a significant amount of weight. As body fat decreases, so does the baseline level of inflammation in the body — which may make it easier for existing psoriasis treatments to work and for skin to stay clearer between flares.

2. A Possible Direct Effect on the Immune System

Perhaps most interesting is that some people report their psoriasis improving before they've lost much weight at all. This suggests GLP-1 medications may have a more direct effect on the immune system — potentially calming some of the same inflammatory signals that cause psoriatic plaques to form. Research in this area is still ongoing, but the early findings are encouraging.

What the Research Shows

We're still in the early stages of understanding exactly how GLP-1 medications affect psoriasis — large dedicated clinical trials are still underway. But the real-world data collected so far is consistent and promising.

What This Means for Your Care

GLP-1 medications are not currently FDA-approved as treatments for psoriasis. But, if you're already managing psoriasis alongside obesity or type 2 diabetes, they may be a meaningful part of your broader care plan and may even help you take less of your psoriasis medications. 

A few things worth knowing before you bring it up with your care team:

• Stomach-related side effects — Nausea, mild diarrhea, or constipation are the most common side effects, especially when starting. These typically ease up over time.
• Temporary hair shedding — Some people experience temporary hair thinning with significant weight loss. Keeping up with protein intake and staying active can help minimize this.
• It takes a team — Because GLP-1 medications sit at the intersection of dermatology and metabolic health, managing them well may involve your Zest care team working alongside your primary care provider or endocrinologist. We're experts in managing systemic inflammation and can help coordinate care with your other providers.
