What is Psoriasis?
An autoimmune condition that mostly affects the skin, psoriasis is not communicable. It happens when defective signals from the immune system speed up the skin cell life cycle. On the surface, these cells accumulate to produce red spots and scales that are occasionally unpleasant and frequently irritating.
A chronic autoimmune disease, psoriasis affects millions of people globally. It is characterized by the quick accumulation of skin cells, which causes redness, irritation, and scaling. Effective psoriasis symptom management requires an understanding of the condition’s intricacies. To offer thorough insights for both patients and medical experts.

What Causes Psoriasis?
While the exact cause of psoriasis remains unclear, several factors contribute to its onset:
Genetic Predisposition
Psoriasis often runs in families. Researchers have identified specific genes linked to the condition, indicating a hereditary component.
Immune System Dysregulation
The immune system mistakenly attacks healthy skin cells, causing inflammation and rapid cell turnover.
Environmental Triggers
Certain triggers can worsen or activate psoriasis in genetically predisposed individuals, such as:
- Stress: Emotional and physical stress can exacerbate symptoms.
- Infections: Strep throat and other infections may trigger psoriasis.
- Medications: Drugs like beta-blockers and lithium can induce flare-ups.
