Understanding the Causes of Psoriasis

Psoriasis is a chronic skin condition characterised by red, flaky, crusty patches of skin covered with silvery scales. These patches usually appear on the elbows, knees, scalp and lower back, but can appear anywhere on the body. The severity of psoriasis varies greatly from person to person.

The exact cause of psoriasis is not fully understood, but it is believed to be linked to a problem with the immune system. The condition occurs when the immune system mistakenly attacks healthy skin cells, leading to an increased production of skin cells. In a typical skin renewal process, skin cells are replaced every three to four weeks; however, with psoriasis, this process occurs every three to seven days, causing a build-up of skin cells.

Genetic Factors

Genetics play a significant role in the development of psoriasis. The condition tends to run in families, suggesting a hereditary aspect. If a parent has psoriasis, there is an increased risk that their children might develop the condition. Researchers have identified several genes that may contribute to the development of psoriasis, although it is likely that a combination of genetic mutations is responsible for triggering the disease.

Immune System and Psoriasis

The immune system is central to the development of psoriasis. The condition is classified as an autoimmune disorder, meaning the body's immune system attacks its own tissues. In psoriasis, T cells, which are a type of white blood cell, become overactive. These T cells attack healthy skin cells, as if they were fighting an infection or healing a wound. This triggers the rapid turnover of skin cells, leading to the symptoms of psoriasis.

Environmental Triggers

Although genetic predisposition is significant, environmental factors can act as triggers for psoriasis flare-ups. Common triggers include stress, skin injuries such as cuts or sunburn, and certain medications like beta-blockers and lithium. Infections, particularly streptococcal throat infections, can also trigger psoriasis in some individuals.

Lifestyle and Other Risk Factors

Unhealthy lifestyle choices can exacerbate psoriasis symptoms. Smoking, excessive alcohol consumption, and obesity are recognised as risk factors that can worsen symptoms. Maintaining a healthy lifestyle with a balanced diet and avoiding known triggers can help manage the condition more effectively.

Conclusion

While there is no cure for psoriasis, understanding its causes and managing triggers can help those affected by the condition. With proper diagnosis and treatment, people with psoriasis can lead a healthy and active life. If you suspect you have psoriasis, it is important to consult a healthcare provider for an accurate diagnosis and appropriate management strategies.

Why Does Psoriasis Happen?

Psoriasis is a skin problem. It makes red, flaky patches on the skin. These patches have silver scales on top. They often appear on the elbows, knees, head, and back. But they can show up anywhere on your body. Psoriasis can be mild or very noticeable. It is different for each person.

Doctors are not sure why psoriasis happens. They think it is because of a problem with the body's defense system (immune system). In psoriasis, the body attacks its own skin cells by mistake. This makes the skin produce new cells too quickly. Normally, skin cells change every three to four weeks. In psoriasis, it happens every three to seven days. This causes the skin to pile up.

Family Causes

Psoriasis can run in families. This means if your mom or dad has psoriasis, you might get it too. Scientists found some genes that might cause psoriasis. But it is probably many different genes working together.

The Immune System and Psoriasis

The body's defense system (immune system) is very important in psoriasis. Psoriasis is an "autoimmune disorder." This means the body attacks itself. In psoriasis, special cells called T cells attack the skin. They act like the skin is hurt or sick. This makes the skin make new cells too fast and causes the psoriasis patches.

Things in the Environment

Some things around us can make psoriasis worse. These are called triggers. Stress, cuts, and sunburn can be triggers. Some medicines might make psoriasis worse too. Another trigger can be a sore throat illness called a streptococcal infection.

Ways of Living and Other Reasons

Living an unhealthy life can make psoriasis worse. Smoking, drinking too much alcohol, and being overweight are not good for psoriasis. Eating well and staying away from triggers can help keep psoriasis from getting worse.

Ending Thoughts

There is no way to make psoriasis completely go away. But, if you know what causes it and what makes it worse, you can handle it better. By getting the right checks and treatment, people with psoriasis can have a good life. If you think you have psoriasis, talk to a doctor. They can help you understand what to do.
