Psoriasis and its impact

Psoriasis can affect the skin and can also lead to psoriatic arthritis, a form of joint inflammation. The disease can affect anyone, regardless of age or gender.

A chronic inflammatory systemic disease

In Sweden, it is estimated that approximately 250,000–300,000 people have psoriasis, making it one of the most common diseases. Despite this, there is a large knowledge gap, both among the general public and within healthcare. Outdated beliefs, such as that psoriasis is only a skin condition or that it is contagious, are still common.

For those living with psoriasis, the disease means that the immune system is not working properly. The immune system attacks its own tissue, which leads to inflammation.

Advances in research

Research shows that psoriasis is a systemic disease that can affect more organs than the skin. Comorbidity is common, so it is important to be aware of symptoms that may indicate other diseases, such as cardiovascular problems, gastrointestinal problems, type 2 diabetes or inflammatory eye diseases. Keeping track of blood pressure and weight, and quitting smoking, can prevent some of these.

Variations of psoriasis

Psoriasis often has flare-ups, which means periods when the disease flares up. The intensity varies between individuals. Some may have mild symptoms and be symptom-free for a long time, while others have more continuous problems. The disease is characterized by a rapid formation of new skin cells, which leads to scaly, red and dry patches of skin. The rash can change over time and is affected by lifestyle and well-being.

Causes of psoriasis

The cause of psoriasis is not fully understood, but heredity plays a major role. The risk increases if the disease runs in the family. Infections, certain medications and psychological stress can also trigger psoriasis.

Joint problems

People with psoriasis can also develop psoriatic arthritis, a joint disease that can cause stiffness, pain, tenderness in muscles and tendon attachments, and swollen joints. Psoriatic arthritis can sometimes occur without skin symptoms. Early diagnosis and treatment are important to slow the progression of the disease.
