Psoriasis increases your risk for many other conditions.
When people think of psoriasis, they may assume that it’s just a skin condition, since most of its symptoms are visible to the naked eye. In actuality, psoriasis starts from the inside and moves outward.
Psoriasis is a chronic autoimmune disease that’s due to faulty signals from the immune system, causing a person’s skin cells to grow too quickly (forming in a few days rather than weeks). The body doesn’t shed these cells, so they pile up on the surface of the skin, which causes patches of psoriasis to appear.
Because psoriasis starts from within, it can affect the body in a multitude of ways. This increases a psoriasis patient’s risk of developing other health conditions.
These are the secondary health conditions that may develop if you have psoriasis, and what you can do to decrease your risk.
Psoriatic Arthritis + Psoriasis
If you have psoriasis, you may already know that you’re at an increased risk of developing psoriatic arthritis (PsA), an inflammatory arthritis that causes joint pain, swelling, and stiffness. About 30 percent of people who have psoriasis eventually get PsA, according to the National Psoriasis Foundation (NPF).
If you are concerned that your skin issues, pain, or other symptoms could be psoriatic arthritis, talk to your doctor. Early diagnosis and treatment will help prevent permanent joint damage and reduce the effect the PsA has on your life.
Cancer + Psoriasis
Studies have shown that people with psoriasis and psoriatic arthritis have an increased risk of certain types of cancer, including lymphoma and nonmelanoma skin cancer. People with psoriasis should talk to their doctor about incorporating regular cancer screenings into their treatment plan.
Heart Disease + Psoriasis
People with severe psoriasis have a significantly higher risk of developing cardiovascular disease than those without. According to the National Psoriasis Foundation, patients with severe psoriasis are 58 percent more likely to have a major cardiac event, such as a heart attack, and 43 percent more likely to have a stroke. Here are the signs your chest pain could be a heart attack and here are the symptoms of a stroke.
How can you lower your risk of heart attack or stroke? Follow your treatment plan and talk to your doctor about your cardiovascular risk.
Depression + Psoriasis
Psoriasis can cause significant emotional distress, including low self-esteem, and an increased chance of mood disorders, such as depression. In fact, people with psoriasis have a 39 percent higher risk of being diagnosed with depression than people without psoriasis, according to the National Psoriasis Foundation. (Learn more about the symptoms of depression.)
“Psoriasis has a profound effect on a patient’s quality of life,” says Suzanne Friedler, MD, a dermatologist in New York City. “Patients with psoriasis do tend to be more depressed and do tend to avoid social encounters than an average patient.”
Inflammatory Bowel Disease + Psoriasis
Having psoriasis and psoriatic arthritis may increase your chances of developing an inflammatory bowel disease, such as Crohn's disease or ulcerative colitis. Both psoriasis and inflammatory bowel disease are associated with chronic inflammation in the body, so it’s no surprise that having one increases the risk of having the other.
Talk to your doctor if you have symptoms of inflammatory bowel disease, such as diarrhea, abdominal cramping, or bloody stools.
Diabetes + Psoriasis
People with psoriasis and psoriatic arthritis are at an increased risk for developing type 2 diabetes. People with severe psoriasis, in particular, are 30 percent more likely to have type 2 diabetes, according to the National Psoriasis Foundation. If you have symptoms of type 2 diabetes, such as increased thirst, blurred vision, or fatigue, tell your doctor.
Controlling your psoriasis may not only help lessen the severity of your symptoms, but it can also help reduce your risk of developing these conditions.
Even though psoriasis can’t be cured, there are plenty of lifestyle adjustments that help psoriasis symptoms—such as eating a psoriasis-friendly diet, relieving stress, and avoiding habits that can cause psoriasis flare-ups. Additionally, there are many psoriasis medications available that may help clear your skin and significantly improve your quality of life and health.

00:00:00,000 --> 00:00:02,510
00:00:02,510 --> 00:00:06,963
Psoriasis has associations with
cardiovascular disease as well as with
00:00:06,963 --> 00:00:11,500
certain types of cancers, diabetes,
inflammatory bowel disease.
00:00:11,500 --> 00:00:14,148
But it doesn't mean that
if you have psoriasis,
00:00:14,148 --> 00:00:17,648
you're definitely going to
contract one of those conditions.
00:00:17,648 --> 00:00:19,810
But there is a higher correlation.
00:00:19,810 --> 00:00:24,030
00:00:24,030 --> 00:00:28,441
Patients with psoriasis have about a 50%
increased risk of cardiovascular disease.
00:00:28,441 --> 00:00:33,079
And cardiovascular disease is a leading
cause of death in patients with psoriasis.
00:00:33,079 --> 00:00:36,719
Patients with psoriasis should pay
particular attention to their weight and
00:00:36,719 --> 00:00:39,240
their cardiovascular fitness,
00:00:39,240 --> 00:00:45,169
And also checking in with
their general practitioner.
00:00:45,169 --> 00:00:47,875
Up to 30% of patients with psoriasis
may develop joint involvement known as
00:00:47,875 --> 00:00:48,700
00:00:48,700 --> 00:00:52,164
Both conditions are of
00:00:52,164 --> 00:00:57,627
where the body can attack itself and
lead to joint destruction and damage.
00:00:57,627 --> 00:01:02,698
Patients often have an increased risk of
developing certain types of lymphoma and
00:01:02,698 --> 00:01:04,920
also non-melanoma skin cancers.
00:01:04,920 --> 00:01:08,750
So it's always a good idea if you have
psoriasis to have regular skin checkups
00:01:08,750 --> 00:01:11,290
by your dermatologist
as well as by your GP.
00:01:11,290 --> 00:01:15,720
Patients with psoriasis are more likely to
have inflammatory bowel diseases such as
00:01:15,720 --> 00:01:18,320
Crohn's and ulcerative colitis.
00:01:18,320 --> 00:01:23,490
If you have psoriasis and you have
abdominal cramping, bloody stools,
00:01:23,490 --> 00:01:26,500
please see your gastroenterologist or
your primary care physician.
00:01:26,500 --> 00:01:30,215
Patients with psoriasis are also at
increased risk of developing type
00:01:30,215 --> 00:01:31,230
00:01:31,230 --> 00:01:32,920
If you notice increased thirst or
00:01:32,920 --> 00:01:35,810
speak with your physician about it.
00:01:35,810 --> 00:01:40,420
Patients often describe their
quality of life as relatively poor,
00:01:40,420 --> 00:01:44,270
only second to patients with
depression on quality-of-life scores.
00:01:44,270 --> 00:01:48,459
If you're a patient with psoriasis
who is feeling low self-esteem or
00:01:48,459 --> 00:01:52,510
is feeling depressed by your condition,
you should seek out help.
00:01:52,510 --> 00:01:57,230
Patients with psoriasis can best serve
themselves by leading a healthy lifestyle.
00:01:57,230 --> 00:02:00,717
A healthy, well-balanced diet,
keeping a healthy weight, and
00:02:00,717 --> 00:02:03,529
taking care of your insides
will help your outsides.
