But it is not enough to have a genetic connection. Flare-ups often occur when certain triggers start the psoriasis process. The most common is stress. Mental stress causes the body to release chemicals that boost the inflammatory response.
Scientists suspect this is the mechanism for stress-induced psoriasis flare-ups. Psoriasis tends to worsen with weight gain. Flare-ups also can be triggered by certain common medications, like beta blockers used to control high blood pressure or heart rate, or lithium used to treat bipolar disorder. Other triggers include strep throat, injury to the skin, and respiratory infection. Once psoriasis has cleared up, it can stay away for months or even years, and then reappear.
Still, you should try to manage and avoid triggers, or at least keep them to a minimum. For instance, lose excess weight, and review your medications with your doctor to see if you should use an alternative or a different dose. Can your diet help keep psoriasis under control?

Spontaneous remission, or remission that occurs without treatment, is also possible.
This allows the symptoms to fade. Watch for symptoms of psoriasis so that you can begin treating them if they reappear. Psoriasis is unpredictable, and psoriasis remission has no timeline. Sometimes, remission can be lengthy. You may not experience symptoms for months, even years. Remission can also be short-lived. You may start experiencing symptoms again within a few weeks of them disappearing.
One common psoriasis cycle involves having fewer symptoms and flares during summer months and more symptoms and flares during winter months. The weather in these two seasons can trigger psoriasis symptoms. Being aware of these triggers and others can help you reduce flare frequency and extend remission periods. Although psoriasis may return on its own, something may prod its return.
These things are called triggers. Being aware of the most common ones can help you reduce the likelihood of flares and possibly extend periods of remission.
