No one knows exactly what causes psoriasis, but genes are believed to play a role. Approximately one-third of psoriasis sufferers have a close relative with the disease. In addition to family history, other risk factors are obesity, medical conditions such as HIV or recurring infections such as strep throat, smoking and stress [source: Mayo Clinic].
Environmental factors also seem to play a role. In fact, many psoriasis sufferers find that certain factors will trigger an outbreak or worsen one that is already underway. Triggers include an infection, a skin injury such as a scrape or sunburn, cold weather, alcohol consumption, stress and some medications [source: Mayo Clinic].
The physical component of dealing with psoriasis ranges from mild disruption to severe disruption of daily life. Psychological complications are not unusual, especially when the condition is readily visible to others, as can happen with scalp psoriasis. Some people suffer from depression, stress and anxiety as a result. They may withdraw to escape the social stigma that outsiders at times attach to the condition.
