Luckily, treating your PsA inflammation can help prevent these problems.
In a way, psoriatic arthritis (PsA) is already a complication in itself. For many people, PsA is something that develops from psoriasis, a skin condition.
“Not all people with psoriasis get psoriatic arthritis,” says Nicola Kim Berman, MD, a rheumatologist based in New York. “But there is definitely a clear association with the skin condition and the arthritis condition.” About 30 percent of people with psoriasis go on to develop PsA, according to the Arthritis Foundation.
Like psoriasis itself, PsA is an autoimmune disease that causes chronic inflammation. When someone has any type of inflammatory condition, their risk for other inflammatory problems increases.
Thus, there are a number of complications that can arise from PsA, especially if the inflammation is not managed. “It’s essentially just an inflammatory process occurring in different parts of your body,” says Dr. Berman.
“A big complication of psoriatic arthritis is metabolic syndrome,” says Dr. Berman. “That’s a combination of high blood pressure, [high blood sugar], abdominal obesity, [and] high blood pressure.” Statistically, having psoriasis or PsA doubles the risk of having metabolic syndrome, according to the Arthritis Foundation.
Metabolic syndrome is not a disease in itself, but it’s a cluster of conditions that increases the risk of several diseases, especially heart disease and type 2 diabetes. As a result, regular visits to your primary care doctor to keep tabs on your blood pressure and blood sugar is essential.
Inflammatory Bowel Diseases
Another common complication of PsA is inflammatory bowel disease, which includes Crohn’s disease and ulcerative colitis. The relationship goes both ways: Having inflammatory bowel disease can also increase the risk of developing psoriasis and PsA.
These conditions cause inflammatory attacks on parts of the digestive tract and lead to symptoms like diarrhea, bloody stools, and abdominal pain. Learn more about the symptoms of ulcerative colitis here.
Inflammatory Eye Diseases
A common complication associated with many autoimmune conditions is inflammation in the eyes. This condition is known as uveitis, or inflammation of the middle layer of the eye. Uveitis can lead to damage in the eye tissue and even compromise vision, according to the U.S. National Eye Institute.
“Things to look out for would be painful, hot, red eyes or blurred vision. It usually will present in one eye, and rarely in both,” says Dr. Berman.
Additionally, people with PsA are more likely to develop conjunctivitis—better known as “pink eye”—and dry eye syndrome.
Since PsA and psoriasis are closely linked, you might expect to experience skin issues with PsA. However, it’s not just the thick, scaly plaques associated with psoriasis that people with PsA should look out for; rashes and skin ulcers are also common complications.
“Another thing that [patients with PsA] should also be screened for by their primary care doctor would be depression,” says Dr. Berman. “There’s a really high incidence of depression amongst these populations, and it’s something to be aware of with your patients.”
Mental illness and psoriatic diseases are a two-way street: Having one increases the risk of having the other. Specifically, people with psoriasis have a 39 percent higher risk of being diagnosed with depression than people without psoriasis, according to the National Psoriasis Foundation. That number is believed to be higher for people with PsA.
One explanation is that dealing with chronic diseases is inherently stressful and can cause feelings of hopelessness. However, there’s also evidence that chronic inflammation actually alters brain functioning.
The best way to prevent complications of PsA is to stick to your prescribed treatment regimen and keep inflammation at bay. Learn more about treatments for psoriatic arthritis here.

Psoriatic arthritis is an inflammatory
arthritis that's associated with the skin
00:00:06,222 --> 00:00:07,730
00:00:07,730 --> 00:00:09,768
When you have psoriatic arthritis,
00:00:09,768 --> 00:00:13,778
it's important to have an understanding
of your condition itself, and
00:00:13,778 --> 00:00:17,935
the complications of your condition,
and when to seek help from a doctor.
00:00:17,935 --> 00:00:23,546
00:00:23,546 --> 00:00:27,515
A big complication of psoriatic
arthritis is metabolic syndrome.
00:00:27,515 --> 00:00:32,275
That's a combination of high blood
pressure, diabetes, and obesity, and
00:00:32,275 --> 00:00:34,120
00:00:34,120 --> 00:00:37,681
And so I think regular doctors
appointments are very, very important.
00:00:37,681 --> 00:00:41,367
Checking in with your primary care doctor
every couple months to check your blood
00:00:41,367 --> 00:00:44,252
pressure, check your blood sugars,
and your lipids as well.
00:00:44,252 --> 00:00:49,560
I would also say that it's important
to understand your medication.
00:00:49,560 --> 00:00:52,000
Biologic therapies are therapies that are
used for, not only psoriatic arthritis,
00:00:52,000 --> 00:00:53,260
but a lot of different
00:00:55,710 --> 00:01:00,970
Essentially what they do, is they target
the immune system at a very minute level
00:01:00,970 --> 00:01:05,000
in order to prevent your immune
system from acting against your body.
00:01:05,000 --> 00:01:08,930
And so what they're doing is
with any autoimmune condition,
00:01:08,930 --> 00:01:10,440
your immune system is very active.
00:01:10,440 --> 00:01:13,650
And these biologic therapies essentially
shut down the immune system,
00:01:13,650 --> 00:01:16,489
however, it's not only preventing
your autoimmune disease,
00:01:16,489 --> 00:01:19,712
it's preventing your immune system
from working properly in general.
00:01:19,712 --> 00:01:23,798
So there's a very increased risk
of infection when it comes to
00:01:23,798 --> 00:01:25,691
a lot of these medications.
00:01:25,691 --> 00:01:30,031
When you're taking these therapies you
have to be very cautious of infection.
00:01:30,031 --> 00:01:32,465
If there is a bug going around
you're more likely to get it and
00:01:32,465 --> 00:01:34,291
you're more likely to
get very sick from it.
00:01:34,291 --> 00:01:38,592
So things like immunizations for
non-live vaccines are important.
00:01:38,592 --> 00:01:40,980
And if you work in a daycare or
00:01:40,980 --> 00:01:44,131
you have to be careful to wear
a mask during flu season.
00:01:44,131 --> 00:01:47,271
Just be careful around the people
that you know might be sick.
00:01:47,271 --> 00:01:50,742
Certain things like surgery or
00:01:50,742 --> 00:01:53,872
even something as small as a UTI or
a skin infection.
00:01:53,872 --> 00:01:56,532
And even a surgery as
small as a dental surgery,
00:01:56,532 --> 00:01:58,671
your doctor's going to want to know.
00:01:58,671 --> 00:02:02,642
A lot of people who take their
medication correctly and
00:02:02,642 --> 00:02:07,993
live a healthy lifestyle, and
really focus on controlling and caring for
00:02:07,993 --> 00:02:13,400
their condition do very, very well,
and live a normal lifestyle.
00:02:13,400 --> 00:02:17,464
And are able to return to baseline, and
that should be what everyone strives for.
