Psoriasis is a chronic skin condition that affects millions of people worldwide. It is characterised by red, itchy, and scaly patches on the skin. The exact cause of psoriasis is still unknown, but it is believed to be an autoimmune disease, where the immune system mistakenly attacks healthy skin cells. In this blog, we will delve into the multifaceted realm of Psoriasis, providing you with a deep understanding of its definition, underlying causes, wide-ranging symptoms, available psoriasis treatments, and effective prevention strategies to empower you in managing this complex skin condition.

Types of Psoriasis

In this section, we will delve into the different types of Psoriasis.

1. Plaque Psoriasis

Plaque psoriasis is the most common type, accounting for about 80% of all cases. It is characterised by raised, inflamed patches covered with silvery-white scales. These patches often develop on the elbows, knees, lower back, and scalp. Some symptoms of Plaque Psoriasis include:

• Red, raised patches covered with thick scales
• Itching and burning sensations
• Dry and cracked skin that may bleed
• Nail changes, such as pitting or ridges

2. Guttate Psoriasis

Guttate Psoriasis is a type of psoriasis that often appears as small, drop-shaped lesions on the skin. It is usually triggered by a bacterial or viral infection, such as strep throat. This type of psoriasis is more common in children and young adults but can affect people of all ages.

Symptoms of guttate psoriasis include small, red, scaly spots on the skin. These spots are typically found on the trunk, limbs, and scalp. They may be itchy and can sometimes be accompanied by a sore throat or fever if an infection is present.

3. Inverse Psoriasis

Inverse Psoriasis is a type of psoriasis that affects the skin folds, such as the armpits, groin, and under the breasts. Unlike other forms of psoriasis, it appears as smooth, red patches without the typical scaling. This can make it harder to diagnose and differentiate from other skin conditions.

The exact cause of Inverse Psoriasis is unknown, but it is believed to be related to an overactive immune system. Risk factors include obesity, family history of psoriasis, and certain medications. Some symptoms include:

• Smooth, red patches of skin in areas like armpits, groin, and under the breasts
• The skin may be shiny and appear moist
• Itching and discomfort in affected areas
• Increased sensitivity to friction and sweat

4. Pustular Psoriasis

Pustular Psoriasis is characterised by the presence of pus-filled blisters or pustules on the skin. The causes of Pustular Psoriasis can vary from person to person, but certain triggers may contribute to flare-ups. These triggers can include:

• Infections
• Certain medications, such as lithium or corticosteroids
• Exposure to certain chemicals or irritants
• Hormonal changes, such as during pregnancy or menopause

Symptoms of Pustular Psoriasis include:

• Pus-filled blisters or pustules
• Red and inflamed skin surrounding the pustules
• Itching or burning sensation
• Skin tightness or tenderness
• Flaking or scaling of the skin, which can lead to silver-white patches

5. Erythrodermic Psoriasis

Erythrodermic Psoriasis is a severe form of psoriasis that affects the entire body. It is a rare condition, accounting for only about 2% of all psoriasis cases. Certain factors can trigger or exacerbate flare-ups of erythrodermic psoriasis, including:

• Stress
• Infections
• Withdrawal from systemic corticosteroids

This type of psoriasis is characterised by widespread redness, scaling, and inflammation of the skin. The symptoms can be intense and may include:

• Itching
• Burning
• Pain
• Peeling of the skin

Common Triggers for Psoriasis Flare-ups

While the exact cause of psoriasis is unknown, several common triggers can lead to flare-ups. Understanding these triggers can help individuals manage their condition effectively.

1. Stress and Emotional Factors

Stress plays a major role in triggering psoriasis flare-ups. Emotional stress, such as anxiety or depression, can lead to increased inflammation and worsen the symptoms.

2. Cold Weather and Dry Skin

Psoriasis tends to worsen during cold weather due to low humidity levels. Cold temperatures and dry air can cause the skin to become dry and flaky, leading to an increase in psoriasis symptoms.

3. Infections and Illnesses

Certain infections, such as strep throat or respiratory infections, can trigger or worsen psoriasis flare-ups. It is important to promptly treat any infections to minimise the impact on psoriasis.

4. Certain Medications

Some medications, such as lithium, antimalarials, and beta-blockers, have been known to aggravate psoriasis symptoms. It is important to discuss potential side effects with your healthcare provider before starting any new medication.

5. Hormonal Changes

Hormonal changes during pregnancy or menopause can affect the immune system and trigger psoriasis flare-ups. Women with psoriasis need to be aware of these hormonal changes and work closely with their healthcare provider to manage their condition effectively.

Managing Psoriasis Symptoms and Flare-ups

Treating and managing psoriasis symptoms and flare-ups typically involves a multidisciplinary approach.

1. Topical Treatments

Topical treatments are often the first line of defence in managing scalp psoriasis symptoms. These medications can be applied directly to the affected areas of the skin. Common types of topical treatments include:

• Corticosteroids
• Vitamin D analogues
• Coal tar preparations
• Salicylic acid

These treatments help reduce inflammation, alleviate itching, and slow down the growth of skin cells.

2. Phototherapy

Phototherapy involves exposing the skin to ultraviolet light under medical supervision. There are different types of phototherapy, including UVB therapy and PUVA therapy.

Phototherapy helps slow down the growth of skin cells and reduce inflammation. It can be an effective treatment option for individuals with moderate to severe psoriasis.

3. Systemic Medications

Systemic medications are taken orally or by injection. They work throughout the body to reduce inflammation and suppress the immune system's response that triggers psoriasis. Examples of systemic medications for scalp psoriasis include:

• Methotrexate
• Cyclosporine
• Acitretin

4. Biologic Drugs

Biologic drugs are a newer class of medications that target specific parts of the immune system involved in psoriasis. They are usually given by injection or infusion.

Biologics can be highly effective in managing moderate to severe psoriasis symptoms when other treatments have failed.

Lifestyle Adjustments for Psoriasis

In addition to medical psoriasis treatments prescribed by your doctor, making certain lifestyle changes can also be beneficial.

1. Dietary Suggestions

Some dietary adjustments to manage psoriasis are:

• Maintain a Healthy Weight: Obesity is linked to an increased risk of psoriasis and can worsen symptoms.
• Include Anti-inflammatory Foods: Incorporate foods like fruits, vegetables, whole grains, and lean proteins into your diet to reduce inflammation in the body.
• Limit Alcohol Consumption: Alcohol can trigger psoriasis flare-ups, so it's best to drink in moderation or avoid it altogether.
• Reduce Processed Foods: These can contribute to inflammation in the body, so try to minimise their intake.

2. Regular Exercise and Physical Activity

Engaging in regular physical activity can contribute to overall well-being.

• Engage in Low-impact Exercises: Activities like swimming, yoga, or walking can help reduce stress and inflammation.
• Maintain a Regular Exercise Routine: Aim for at least 30 minutes of physical activity most days of the week to improve overall health and manage stress levels.

3. Stress Management Techniques

Stress is a common trigger for psoriasis flare-ups.

• Practice Relaxation Techniques: Incorporate practices like deep breathing exercises, meditation, or mindfulness techniques into your daily routine to manage stress.
• Engage in Hobbies or Activities: Doing things that bring you joy can help distract from psoriasis-related stressors.
• Seek Support: Connect with others who have psoriasis through support groups or online communities to share experiences and coping strategies.
