Q. What is the major cause of psoriasis?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Psoriasis is a chronic autoimmune condition that affects the skin, characterized by red, scaly patches. The exact cause of psoriasis is not fully understood, but it is believed to involve a combination of genetic, immune system, and environmental factors.
Genetics plays a significant role in predisposing individuals to psoriasis. It tends to run in families, and people with a family history of psoriasis are at a higher risk of developing the condition themselves.
The immune system also plays a crucial role in psoriasis. In psoriasis, the immune system mistakenly attacks healthy skin cells, leading to inflammation and rapid turnover of skin cells. This results in the formation of the characteristic red, scaly patches seen in psoriasis.
Environmental factors, such as stress, certain medications, infections, and lifestyle factors like smoking and alcohol consumption, can also trigger or exacerbate psoriasis symptoms in susceptible individuals.
Overall, while the exact cause of psoriasis remains elusive, it is likely a complex interplay of genetic predisposition, immune dysfunction, and environmental triggers.
