Symptoms, Causes, And Treatment for Psoriasis

Psoriasis is a chronic skin condition that results in the formation of itchy, scaly patches on different parts of the body, such as the scalp, elbows, knees, and trunk. Despite being prevalent, there is currently no known cure for psoriasis, and it can cause discomfort, disrupt sleep patterns, and hinder concentration. Symptoms tend to come and go in cycles, with periods of flare-ups and remission. People with a genetic predisposition to psoriasis may experience triggers such as infections, cuts or burns, and certain medications. However, various treatments are available to alleviate symptoms, and modifying one’s lifestyle and coping mechanisms can improve the quality of life for people living with psoriasis.

Common Signs and Symptoms of Psoriasis

Psoriasis can manifest differently from one person to another, and the appearance of the rash can vary depending on skin color. The patches can range from small scaling spots to major eruptions over much of the body. They can appear on different parts of the body, such as elbows, knees, lower back, and scalp. The patches can be painful, itchy, and cause discomfort. The affected skin can also become dry and cracked, leading to bleeding and discomfort.
Cyclic rashes are common in people with psoriasis, with flare-ups occurring for a few weeks or months and then subsiding. The rashes can also appear in different forms, including spots of dandruff-like scaling, small scaling spots in children, and patches with silver or gray scales on white or brown/black skin, respectively.

Types of Psoriasis

Psoriasis can present in several different types, each with unique signs and symptoms. Understanding the different types of psoriasis can help individuals seek appropriate treatment and manage their condition effectively.
Plaque psoriasis: This is the most common type of psoriasis, accounting for about 80-90% of all cases. It appears as raised, red patches of skin covered with a silvery-white scale. The patches can vary in size, and they may be itchy or painful. They usually appear on the elbows, knees, lower back, and scalp.
Nail psoriasis: Psoriasis can also affect the nails, causing pitting, abnormal growth, and discoloration. The nails may become loose and separate from the nail bed, and severe disease may cause the nail to crumble.
Guttate psoriasis: This type of psoriasis is most common in children and young adults and usually occurs after a bacterial infection, such as strep throat. It is characterized by small, drop-shaped, scaling spots on the trunk, arms or legs.
Inverse psoriasis: Inverse psoriasis affects skin folds of the groin, buttocks, and breasts, causing smooth patches of inflamed skin that worsen with friction and sweating. Fungal infections may trigger this type of psoriasis.
Pustular psoriasis: This rare type of psoriasis causes clearly defined pus-filled blisters. It can occur in widespread patches or on small areas of the palms or soles.
Erythrodermic psoriasis: This is the least common type of psoriasis, but it can be the most serious. It can cover the entire body with a peeling rash that can itch or burn intensely. It can be short-lived (acute) or long-term (chronic).

Causes

The exact cause of psoriasis is unknown, but it is believed to be a combination of genetic and environmental factors. Psoriasis is not contagious, and you cannot catch it from someone else.

Psoriasis Triggers

While psoriasis can occur at any age, it is most commonly diagnosed in adults. Many people who are genetically predisposed to the condition may remain symptom-free for years until an environmental trigger sets off the disease. Here are some common triggers that can cause psoriasis to flare up:
Infections: Infections such as strep throat, respiratory infections, and skin infections can trigger psoriasis. The body’s response to the infection can trigger an immune system response that leads to a psoriasis flare-up.
Weather: Cold, dry weather can trigger psoriasis symptoms, as can exposure to excessive heat or sunlight.
Injury to the skin: Any injury to the skin, such as a cut, scrape, bug bite, or severe sunburn, can cause a psoriasis flare-up.
Lifestyle factors: Lifestyle factors, such as smoking, excessive alcohol consumption, and stress, can trigger psoriasis.
Medications: Certain medications, including lithium, high blood pressure drugs, and antimalarial drugs, can trigger psoriasis.
Rapid withdrawal of oral or injected corticosteroids: Stopping oral or injected corticosteroids abruptly can trigger a psoriasis flare-up. It is essential to taper off these medications under the guidance of a healthcare provider to avoid triggering a flare-up.
In conclusion, while the exact cause of psoriasis is unknown, it is believed to be a combination of genetic and environmental factors. Many people who are predisposed to the condition may remain symptom-free for years until a trigger sets off the disease. By identifying and avoiding triggers, people with psoriasis can manage their symptoms and improve their quality of life.

Complications

People with psoriasis are at greater risk of developing other conditions, such as psoriatic arthritis, which causes pain, stiffness, and swelling in and around the joints. Other potential complications include temporary skin color changes where plaques have healed, eye conditions like conjunctivitis, blepharitis, and uveitis, obesity, type 2 diabetes, high blood pressure, cardiovascular disease, and other autoimmune diseases like celiac disease, sclerosis, and Crohn’s disease. Mental health conditions like low self-esteem and depression are also more common in people with psoriasis.

Treatments

Fortunately, there are many treatment options available for psoriasis. Some treatments slow down the growth of new skin cells, while others alleviate itching and dry skin. The right treatment plan depends on several factors, including the size and location of the rash, age, overall health, and other individual considerations.

Common treatments include steroid creams, moisturizers for dry skin, coal tar (available in lotions, creams, foams, shampoos, and bath solutions), vitamin D-based cream or ointment (stronger than over-the-counter versions), retinoid creams, calcineurin inhibitors, and anthralin. It is important to discuss treatment options with a healthcare professional before trying any remedy.

Conclusion

Psoriasis is a chronic condition that affects millions of people worldwide. While there is no known cure, understanding the different types of psoriasis and their symptoms can help individuals seek appropriate treatment and manage their condition effectively. Seeking medical attention from a dermatologist is recommended for anyone experiencing symptoms of psoriasis.
