Psoriasis is a chronic (long-lasting) disease in which the immune system becomes overactive, causing skin cells to multiply too quickly, leading to red, scaly patches on areas like the scalp, knees, elbows, and other parts. One in three people with psoriasis may also develop psoriatic arthritis. While there is no permanent cure for psoriasis, several effective psoriasis treatment are available to manage symptoms and reduce flare-ups, helping those affected live comfortably and confidently.
What Causes Psoriasis?
People with psoriasis experience faster-than-normal skin cell production. Normally, skin cells are produced and replaced every three to four weeks. However, in psoriasis patients, this process takes only three to seven days. The accumulation of skin cells leads to flaky, scaly patches. While the exact mechanism is unknown, it is believed to be connected to an immune system issue. The immune system mistakenly targets healthy skin cells, causing inflammation and rapid cell turnover. Psoriasis can run in families, although the exact role of genetics is unclear.
Psoriasis Triggers
Certain factors may trigger or worsen psoriasis symptoms, including:
- Genetic Predisposition: Family history can increase the risk of psoriasis.
- Infections: Ear infections, bronchitis, tonsillitis, or respiratory infections can trigger psoriasis. Streptococcus infections (strep throat) are linked to guttate psoriasis, especially in children.
- Stress: High stress levels are a common trigger and can also exacerbate existing psoriasis symptoms.
- Weather: Cold weather can worsen symptoms due to less sunlight, lower humidity, and dry indoor air. In contrast, warm weather often improves psoriasis due to natural sunlight and higher humidity.
- Certain Medications: Drugs like lithium and beta-blockers can aggravate psoriasis symptoms.

Can Psoriasis Be Cured Permanently?
Currently, there is no permanent cure for psoriasis. However, various psoriasis treatments can help relieve symptoms and reduce flare-ups. A combination of topical applications, lifestyle changes, and natural remedies can enable many people to lead a largely symptom-free life.
Best Treatments for Psoriasis on the Legs
Psoriasis on the legs can be particularly noticeable and irritating. Here are some effective ways to manage it:
- Topical Creams: Corticosteroids, vitamin D analogs, and coal tar can reduce inflammation and scaling.
- Phototherapy: UVB light therapy slows skin cell growth, helping to reduce plaques.
- Moisturizers: Regular use of fragrance-free moisturizers helps prevent irritation and dryness.
- Systemic Medications: For severe cases, oral medications or biologics targeting the immune system may be prescribed.
Foods to Eat and Avoid with Psoriasis
While diet cannot cure psoriasis, certain foods can help reduce inflammation and improve symptoms. Similarly, some foods may trigger flare-ups and should be avoided.
Foods to Eat for Psoriasis
- Fatty Fish (e.g., salmon, mackerel): Rich in omega-3 fatty acids, which reduce inflammation.
- Leafy Greens (e.g., spinach, kale): High in antioxidants with anti-inflammatory properties.
- Berries (e.g., blueberries, strawberries): Packed with antioxidants that promote skin health.
- Nuts and Seeds (e.g., almonds, flaxseeds): Good sources of omega-3s and antioxidants.
- Olive Oil: Helps hydrate the skin and reduce inflammation.
- Whole Grains (e.g., quinoa, brown rice): High in fiber, which helps lower inflammation.
- Turmeric: Known for its strong anti-inflammatory effects.
- Avocados: Contain healthy fats that moisturize the skin.
- Green Tea: Rich in polyphenols that reduce inflammation.

Foods to Avoid with Psoriasis
- Processed Foods: High in sugars and additives that can trigger inflammation.
- Red Meat: Contains arachidonic acid, which may worsen symptoms.
- Dairy Products: Can be inflammatory for some individuals.
- Gluten: Some people with psoriasis are sensitive to gluten.
- Alcohol: May increase inflammation and interfere with treatments.

How to Manage Psoriasis Holistically
Although psoriasis has no permanent cure, a holistic approach combining medical treatments with lifestyle changes can significantly improve symptoms and overall quality of life.
Steps for Holistic Psoriasis Management
- Consult a Dermatologist: Personalized treatments like topical or systemic medications may be recommended based on severity.
- Manage Stress: Practices such as meditation, yoga, and deep breathing can help reduce flare-ups.
- Adopt an Anti-Inflammatory Diet: Focus on whole foods rich in antioxidants and omega-3s.
