Psoriasis: Causes, Symptoms, Treatment & Ayurvedic Remedies

Overview

Psoriasis is a chronic, non-contagious autoimmune skin disease that causes rapid buildup of skin cells, resulting in thick, red, inflamed patches covered with silvery-white scales. It is a long-lasting condition with periods of remission and flare-ups. In India, psoriasis affects approximately 2-3% of the population, with a slightly higher prevalence in men. The condition can range from mild (covering less than 3% of the body) to severe (covering more than 10%). Psoriasis is not just a skin problem; it can also affect joints (psoriatic arthritis) and is associated with other health conditions like cardiovascular disease, diabetes, and depression.

Causes

The exact cause of psoriasis is unknown, but it is believed to be a combination of genetic, immune system, and environmental factors. The immune system mistakenly attacks healthy skin cells, causing an overproduction of new skin cells. Common triggers include:

• Genetic predisposition: Family history increases risk.
• Immune system dysfunction: T-cells attack healthy skin cells.
• Infections: Strep throat is a common trigger, especially in children.
• Stress: Emotional stress can worsen or trigger flare-ups.
• Injury to skin: Cuts, scrapes, sunburn, or bug bites can trigger psoriasis (Koebner phenomenon).
• Medications: Beta-blockers, lithium, antimalarials, and certain anti-inflammatory drugs.
• Lifestyle factors: Smoking, alcohol consumption, and obesity.
• Weather: Cold, dry weather can worsen symptoms.

Symptoms

Psoriasis symptoms vary depending on the type. The most common form is plaque psoriasis. Symptoms include:

• Red, raised, inflamed patches of skin (plaques): Usually covered with silvery-white scales.
• Itching, burning, or soreness: Common in affected areas.
• Dry, cracked skin: May bleed.
• Thickened, pitted, or ridged nails: Nail psoriasis.
• Swollen and stiff joints: Psoriatic arthritis.
• Small, scaly spots: Guttate psoriasis (common in children).
• Pus-filled blisters: Pustular psoriasis (rare but severe).
• Red, raw skin in folds: Inverse psoriasis.

Diagnosis

Diagnosis is typically based on a physical examination and medical history. A dermatologist will examine the skin, scalp, and nails. In some cases, a skin biopsy (removing a small piece of skin for microscopic examination) may be performed to confirm the diagnosis and rule out other conditions. Blood tests may be done to rule out other causes of inflammation or to check for psoriatic arthritis.

Treatment Options

Treatment aims to reduce inflammation, slow skin cell growth, and remove scales. Options include:

Topical Treatments

• Corticosteroids: Reduce inflammation and itching.
• Vitamin D analogues: Slow skin cell growth.
• Coal tar: Reduces scaling and itching.
• Salicylic acid: Removes scales.
• Topical retinoids: Normalize skin cell growth.

Phototherapy (Light Therapy)

• UVB phototherapy: Slows skin cell growth.
• PUVA: Psoralen + UVA light therapy.
• Excimer laser: Targets specific plaques.

Systemic Medications

• Methotrexate: Suppresses immune system.
• Cyclosporine: Immune suppressant.
• Biologics: Target specific immune cells (e.g., adalimumab, etanercept, infliximab, ustekinumab).
• Oral retinoids: Acitretin.

Lifestyle and Home Remedies

• Moisturizers: Keep skin hydrated.
• Oatmeal baths: Soothe itching.
• Stress management: Yoga, meditation.
• Avoid triggers: Infections, smoking, alcohol.

Prevention

Psoriasis cannot be prevented, but flare-ups can be minimized by:

• Managing stress: Practice relaxation techniques.
• Avoiding skin injuries: Use caution with cuts and scrapes.
• Maintaining a healthy weight: Obesity can worsen symptoms.
• Limiting alcohol and quitting smoking: Both are known triggers.
• Moisturizing regularly: Prevents dryness and cracking.
• Identifying and avoiding personal triggers.

Ayurvedic Perspective & Remedies

In Ayurveda, psoriasis is known as Kitibha or Ekakushtha, considered a type of Kushtha (skin disease). It is believed to be caused by an imbalance of Vata and Kapha doshas, leading to toxin accumulation (Ama) in the body. Ayurvedic treatment focuses on detoxification, balancing doshas, and rejuvenation.

Ayurvedic Remedies:

• Neem (Azadirachta indica): Purifies blood and reduces inflammation. Used as paste, oil, or supplements.
• Turmeric (Curcuma longa): Anti-inflammatory and antioxidant. Taken internally or applied as paste.
• Aloe vera: Soothes skin, reduces redness and scaling.
• Guggul (Commiphora wightii): Purifies blood and reduces inflammation.
• Triphala: Detoxifies and improves digestion.
• Dietary changes: Avoid sour, spicy, and fermented foods; include fresh vegetables, fruits, and whole grains.
• Panchakarma: Detoxification procedures like Virechana (purgation) and Raktamokshana (bloodletting) may be recommended by an Ayurvedic practitioner.

Important: Ayurvedic treatments should be taken under the guidance of a qualified Ayurvedic doctor. Do not discontinue conventional treatments without consulting your dermatologist.
