People with moderate to severe psoriasis have a life expectancy that is, on average, five years shorter than people without psoriasis. This is primarily due to an increased risk of cardiovascular disease. However, managing psoriasis symptoms may decrease the risk for comorbidities — and help increase life span.

Psoriasis is a chronic skin condition that affects millions of people worldwide. It is not contagious and has no cure, but it can be managed with treatments and lifestyle changes.
Psoriasis is caused by an overactive immune system that speeds up the growth of skin cells. This leads to a buildup of cells on the surface of the skin, forming plaques or scales.
Psoriasis can be triggered by various factors, such as infections, stress, injuries, medications, or weather changes. The most common type is plaque psoriasis, which causes red or purple patches with silvery scales on the elbows, knees, scalp, and lower back.

Other types include guttate psoriasis, which causes small spots on the torso, arms, and legs; inverse psoriasis, which affects the skin folds of the groin, buttocks, and breasts; nail psoriasis, which affects the fingernails and toenails; pustular psoriasis, which causes pus-filled blisters; and erythrodermic psoriasis, which covers most of the body with a red rash.
Psoriasis can affect your quality of life and increase your risk of other health problems, such as diabetes, heart disease, depression, and arthritis. Therefore, it is important to seek medical advice if you have symptoms of psoriasis or if your condition worsens.
Your doctor can diagnose psoriasis by examining your skin and asking about your medical history. They may also perform a skin biopsy or a blood test to rule out other conditions.
