Psoriasis is an auto-immune skin condition that affects millions of individuals globally, appearing as red, scaly patches that may be found anywhere on the body. Although its etiology remains multi-factorial, genetics play a major role in dictating one's susceptibility. Understanding the genetic component of psoriasis can allow individuals to be active partners in prevention and control.
The Genetic Connection: Is Psoriasis Inherited?
According to Dr. Rashmi Aderao, Dermatology Consultant at Ruby Hall Clinic, Pune, research indicates that genetics play a strong role in the development of psoriasis. Studies put the risk at approximately 10 percent to 20 percent if one parent has psoriasis. If both parents have psoriasis, the risk can be up to 50 percent or higher.
Psoriasis is linked with certain genes that are immune system related. One of the most well-known is HLA-Cw6, a genetic mutation that is also highly predictive for psoriasis that develops early in life. However, having these markers does not always result in someone having psoriasis — it just makes it more likely. Environmental and lifestyle issues also play a big role in whether the disease will manifest.

Common Triggers That May Activate Psoriasis
Even for those with a genetic predisposition, psoriasis usually requires a "trigger" to become active, says Aderao. Triggers are as follows:
• Stress: Physical or emotional stress will induce flare-ups.
• Infections: Frequently streptococcal throat infections.
• Skin Injuries: Cuts, scrapes, sunburn can initiate lesions (Koebner phenomenon).
• Medications: Certain drugs, for example, beta-blockers, lithium, antimalarials, can trigger worsening of psoriasis.
• Weather: Cold, dry weather may aggravate symptoms.• Smoking and Alcohol: Both have been found to heighten severity and risk of psoriasis.
What Physicians Prescribe for Prevention and Treatment
Although psoriasis cannot be prevented entirely, especially if you have the genetic predisposition, there are measures that can slow down or minimize the severity:
1. Be Aware of Your Family History
If your relatives have psoriasis, it alerts your healthcare provider so they can monitor signs early on and create a personalized care program.
2. Maintain Healthy Immune Function
Because psoriasis is an autoimmune disorder, maintaining a balanced immune system is important. This means:
• Sleeping well
• Keeping stress under control
• Staying away from known infection causes
3. Use an Anti-inflammatory Diet
Some physicians advise diets filled with omega-3 fatty acids, green leafy vegetables, berries, and whole foods and less red meat, sugar, and processed foods. These eating habits will assist with managing inflammation.
4. Skin Care and Sun Exposure
Daily moisturizing and protecting your skin from injury. Limited natural sunlight may manage mild symptoms, but overexposure is to be avoided.
5. Avoid Known Triggers
If specific drugs, stressors, or environmental stimuli precipitated flare-ups in the past, avoiding such precipitants may avoid recurrence.
6. Early Medical Care
When symptoms first appear dry, itchy, or scaly patches consult a dermatologist. Early therapy, topical, systemic, or biologic, can prevent progression and improve quality of life.
While genetics loads the gun, lifestyle and environmental factors often cock the trigger in the instance of psoriasis. Active management and vigilance can have a significant difference for those with a family history of the disease. With active cooperation, those at risk are better equipped to handle this chronic condition with confidence.
