Since very few people have GPP, your doctor may not recognize it right away

Diagnosing GPP can take time

As a chronic disease that doesn’t go away, generalized pustular psoriasis (GPP) symptoms can be very difficult to live with. The good news is there are treatments that can help. Getting an accurate diagnosis as soon as possible is a key step in finding the treatment that may be best for you.

GPP is diagnosed and treated primarily by dermatologists, but some rheumatologists may also diagnose the condition. Many doctors haven’t seen GPP before, and it can look like other conditions, so it can be tough to confirm. Often, GPP is diagnosed during or after a flare, when a person experiences a sudden eruption of pustules.

If you suspect you may have GPP, it can help to see a specialist who has experience with the disease and to learn more about it before your conversation. Your doctor may ask about your symptoms, medical history, and any family history of skin conditions.

Taking an active role in your diagnosis can help you get answers faster

About half of people living with GPP also have plaque psoriasis. Since each disease is different, knowing which one you may have or whether you live with both conditions is important.

Here are some steps you can take to help confirm your diagnosis and find the right care plan:
