Diagnosing Psoriasis
The diagnosis of psoriasis is made based on a patient’s medical history, physical examination, and laboratory tests. The doctor will ask the patient about their symptoms, such as the location, severity, and duration of the lesions. The doctor will also perform a physical examination, which may include examining the skin under a Wood’s lamp. Laboratory tests may be ordered to rule out other conditions that can cause similar skin lesions, such as a fungal infection or eczema.
Treatment for Psoriasis
There is no cure for psoriasis, but there are treatments that can help control the symptoms. The type of treatment that is best for a patient will depend on the severity of the psoriasis and the patient’s individual preferences.
Some of the treatments for psoriasis include:
- Topical treatments, such as creams, ointments, and gels
- Phototherapy, which uses ultraviolet light to treat the skin
- Systemic medications, such as oral medications and biologics
