Role of Central Abdominal Fat in Psoriasis- New Study Reveals

Have you ever been diagnosed with psoriasis, and later told you had a “mild” dysfunction of another?
You think it’s nothing serious, so you move on. Until one day, it isn’t mild anymore.

One of my patients lived this reality.

He was fine, or so he thought. Psoriasis was his main concern—itchy, scaly, frustrating, but manageable. Then, during a routine screening, he was told he had mild diastolic dysfunction. No major red flags. No urgency. So, he carried on. Until the morning he collapsed from a heart attack.
After stabilizing him, the immunologist asked a question no one had considered before: “Has anyone checked your visceral fat?
That’s when the real story unfolded.

Most people associate psoriasis with immune dysfunction & genetics. But a recent study from King’s College London confirms this connection: visceral adiposity, especially in the central abdomen, is independently linked to psoriasis and early heart dysfunction—even in people who seem metabolically normal.” This isn’t just about your weight. It’s about what your body is silently storing, and how it’s responding beneath the surface—long before symptoms force you to listen.

It’s Not About How Much You Weigh—It’s About How Much and Where the Fat Sits

We’ve been conditioned to focus on the scale.
But when it comes to health risks like psoriasis, the number on the scale often tells us very little. What matters far more is where fat is stored—and how it behaves inside the body.

This is where visceral fat becomes a key player.

Visceral fat is not the soft fat you feel under your skin. It’s the deep, internal fat that wraps around your organs—your liver, pancreas, and intestines. Unlike subcutaneous fat, which is mostly inert, visceral fat is biologically active. It secretes inflammatory chemicals, disrupts hormonal balance, and impairs immune regulation.

Visceral fat doesn’t just sit there. It sends signals. And those signals fuel chronic inflammation—exactly what psoriasis thrives on.

That’s why someone with a “normal” BMI can still be at risk. You may look fit on the outside but carry dangerous levels of internal fat that silently inflame your system from the inside out. The recent study out of King’s College London confirms this:
Waist circumference, waist-to-hip ratio, and trunk fat—all markers of visceral fat—had a much stronger link to psoriasis than total body weight or BMI.

This means:

A lower weight doesn’t guarantee lower the risk of Psoriasis

Visceral fat is a modifiable driver of systemic inflammation

Tracking fat distribution is more informative than tracking weight.

So rather than asking, “How much do I weigh?”
A better question is: “How inflamed is my body, and where is that inflammation coming from?”

In many cases, the answer starts with fat you can’t see—but your immune system can absolutely feel.

How Inflammation from the Fat Becomes a Skin Disease

It’s one thing to say fat and psoriasis are connected.
But here’s what actually happens beneath the surface—how the fat stored around your abdomen becomes the fuel for a full-blown inflammatory skin condition.

Central Fat Doesn’t Just Sit There—It Sends Signals

Fat around your midsection, especially visceral fat, is not inert.
It’s metabolically active, meaning it constantly sends out chemical messengers called pro-inflammatory cytokines—like IL-6, TNF-alpha, and CRP (C-reactive protein). These act like fire-starters in your system.

The more central fat you carry, the louder and more frequent these inflammatory signals become.

The Immune System Responds—But Overreacts

Your immune system is built to respond to threats. But when it’s constantly exposed to low-grade inflammatory signals from visceral fat, it begins to misfire.
This chronic stimulation pushes the immune system toward dysregulation—the hallmark of autoimmune diseases like psoriasis.
In this inflamed state, immune cells begin to attack healthy skin tissue, leading to:

  • Rapid skin cell turnover
  • Red, scaly patches
  • Persistent irritation and flares

Psoriasis Becomes the Visible Tip of a Deeper Problem

What you see on your skin is just the surface-level outcome.
The real issue is systemic: your body is on constant high alert, and the source of that alert is often centered in your abdomen.

This is why people with higher central fat—not necessarily higher weight—are more prone to psoriasis.
The skin becomes a messenger. But the message starts with internal inflammation—and central fat is often the source.
