Obesity increases the risk and severity of psoriasis through a pro-inflammatory state driven by adipokines (e.g., leptin), cytokines, and gut dysbiosis.
Your body fat is not just stored energy; it actively produces inflammatory signals (like leptin) that can trigger or worsen psoriasis. Managing your weight is not just about aesthetics; it is a direct medical intervention to reduce the inflammatory drive of your skin condition.

obesity is a risk factor for their onset... bidirectional relationship between obesity and psoriasis starts from a pro-inflammatory state coupled with excessive adipokines secretion such as leptin

- Weight loss through caloric restriction and dietary modification significantly reduces psoriasis severity (PASI score) and systemic inflammation in obese patients.Good
- High-fat diets, specifically those rich in palmitic acid, exacerbate psoriasis by promoting gut dysbiosis, increasing intestinal permeability ('leaky gut'), and directly activating keratinocytes and immune cells.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
