What Causes Psoriasis?
While the exact cause of psoriasis is not yet fully understood, there are several known factors that contribute to the development of the condition. Some of the common causes of psoriasis include: (3)
- Genetics: Psoriasis tends to run in families, indicating a genetic component in the development of the disease.
- Immune system dysfunction: Psoriasis is an autoimmune disorder, which means that the body’s immune system mistakenly attacks healthy skin cells, triggering an inflammatory response.
- Environmental triggers: Certain environmental factors, such as stress, trauma, infection, and medications, can trigger psoriasis in susceptible individuals.
- Lifestyle factors: Unhealthy habits like smoking, excessive alcohol consumption, and a poor diet can also increase the risk of developing psoriasis.
- Vitamin D deficiency: It is an important vitamin and its low levels have been linked to the development of psoriasis, and studies suggest that supplementation may help alleviate symptoms.
- Obesity: Being obese has been linked to an increased risk of developing psoriasis and may also worsen symptoms in those already affected.
Of note, while these factors may increase the risk of developing psoriasis, not everyone with these risk factors will develop the condition, and some individuals may develop psoriasis without any known risk factors.
