What causes psoriasis symptoms to flare up (flare-ups)?

Psoriasis symptoms, known as flare-ups, are caused by a complex interaction between genetic and environmental factors. Common triggers include infections, stress, dry skin, and certain medications. These flare-ups can occur periodically, with symptoms subsiding and then reappearing, and their severity varies from person to person. Psoriasis is a chronic skin condition resulting from an overactive immune system, which causes skin cell growth to accelerate. Typically, skin cells take a month to reach the surface, but in the case of psoriasis, this happens within a few days, causing the appearance of thick, red, scaly patches with silvery scales on the skin [2] . Although scientists do not fully understand what causes this erroneous activation of immune cells, they do know that it involves a combination of genetic and environmental factors [3] . Common Environmental Factors That Lead to Psoriasis Flares There are several environmental factors that can increase the likelihood of psoriasis symptoms worsening. The most prominent of these include: Infections: Some types of infections, especially streptococcal infections and HIV, can trigger or exacerbate psoriasis, or lead to its initial onset [3] . For example, guttate psoriasis, a type of psoriasis, often appears after an upper respiratory infection such as strep throat [3] . Stress: Stress is a common trigger that can lead to worsening psoriasis symptoms [2] . Both psychological and physical stress can affect the immune system, increasing inflammation and leading to skin flare-ups. Dry skin: Dry skin can exacerbate the itching and scaling associated with psoriasis, making symptoms more bothersome [2] . Maintaining skin hydration can help alleviate some symptoms. Certain medications: Specific medications can cause psoriasis to flare. These include medications used to treat heart disease, malaria, or mental health issues [3] . It is important to consult your doctor about any medications you are taking to discuss their potential impact on psoriasis. Skin injuries: Skin injuries—such as sunburns, cuts, scrapes, or insect bites—can lead to the appearance of new psoriatic patches in or near the injured area about 10 to 14 days after the injury [4] . Hormonal changes: Menstruation and pregnancy are mentioned as potential triggers specifically for generalized pustular psoriasis; this information is not generalized to all types of psoriasis [1] . Smoking and alcohol consumption: Frequent or excessive smoking and alcohol consumption can make psoriasis treatment less effective and cause persistent flare-ups [4] . Dry and cold weather: Psoriasis may worsen when humidity or temperature drops, such as during winter and autumn [4] . Generalized Pustular Psoriasis and Triggers Generalized Pustular Psoriasis (GPP) is a rare and severe form of psoriasis characterized by recurrent episodes of redness and inflammation over large areas of the skin, with the appearance of small, pus-filled blisters [1] . These flare-ups can be accompanied by fever, severe fatigue, and muscle weakness [1] . Potential triggers for generalized pustular psoriasis include infections, exposure to certain medications or their withdrawal, menstruation, or pregnancy, although the trigger is often unknown [1] . This condition can be life-threatening if left untreated [1] . The Importance of Managing Triggers Understanding and managing triggers can help control psoriasis symptoms and reduce the frequency of flare-ups. It is important to work with a dermatologist to develop a comprehensive treatment plan that includes identifying and avoiding triggers whenever possible, in addition to topical, systemic, or phototherapy treatments [3] .

When to Seek Medical Care? If you experience a sudden and severe worsening of psoriasis symptoms, especially if accompanied by fever, severe fatigue, or a widespread outbreak of pus-filled blisters on the skin, this may indicate generalized pustular psoriasis, a condition requiring urgent medical attention [1] . It is essential to consult a doctor immediately to evaluate the condition and receive appropriate treatment. You should also see a doctor if symptoms significantly impact your quality of life or if you suspect that a particular medication is causing your condition to worsen.
