Itâ€™s hard to believe that the psoriasis plaques on the surface of your skin can put you at risk for serious health problems down the road, but it's true â€” and that risk is real.
Studies continue to show a link between psoriasis and type 2 diabetes, underlining the importance for people with the skin disease to pay attention to their overall health.
The risk was higher even among psoriasis patients who didnâ€™t have other risk factors commonly associated with diabetes, such as obesity. As a result, the researchers estimated 115,500 new cases of diabetes a year are due to the risk from psoriasis.
Understanding the Connection
Both increase inflammation. Chronic inflammation caused by psoriasis is the most important and significant contributing factor for the increased diabetes risk, says Nadia Yaqub, MD, endocrinologist at University of Cincinnati Health in West Chester, Ohio and associate professor of medicine at the University of Cincinnati College of Medicine.
Type 2 diabetes is also a condition of chronic inflammation.
Inflammation caused by psoriasis can also increase the amount of an insulin-like growth factor in the body that is linked to diabetes, explains Andrea Neimann, MD, clinical assistant professor and dermatologist at the Joan H. Tisch Center for Womenâ€™s Health at NYU Langone Medical Center in New York City.
In addition, psoriasis affects your immune system in ways that have been linked to insulin resistance and type 2 diabetes, notes Dr. Neimann.
They share related conditions. Psoriasis is associated with obesity, higher body mass index, high cholesterol, high blood pressure, cardiovascular disease, and stroke. All of those conditions are also intricately related to type 2 diabetes, Neimann says.
Psoriasis and type 2 diabetes are affected by lifestyle. Both diseases are associated with certain lifestyle habits, including smoking, drinking alcohol, and an unhealthy diet. Also, some treatments for psoriasis may make cholesterol and blood sugar levels more difficult to control.
When researchers look for evidence that one disease may potentially affect the risk for another condition, they consider the â€œdose-response effect,â€ Neimann says. That's why the more severe the psoriasis, the higher the risk of diabetes seems to be.
Healthy Living With Psoriasis
Psoriasis complications are not something to ignore, particularly if they include a serious chronic disease like type 2 diabetes. Pay attention to your other risk factors, and work on minimizing them as part of your psoriasis management strategy. That means losing weight if youâ€™re overweight or obese, plus quitting smoking, eating healthy, and exercising regularly, advises Dr. Yaqub.
Some studies have found that weight loss can improve psoriasis, Yaqub says, and certainly losing weight and exercising regularly will improve your bodyâ€™s ability to regulate blood sugar and help stave off type 2 diabetes.
Lowering your weight by just 5 to 10 percent has been found to lower both blood sugar and blood pressure, and reduce your risk for diabetes. Plus, exercising 30 to 60 minutes a day, even if itâ€™s just brisk walking and nothing fancy, is good for your health.
Itâ€™s also vital that you get regular screenings for type 2 diabetes, high blood pressure, and high cholesterol. Talk with all of your doctors, including your dermatologist and primary care physician, about psoriasis and the possible risk of diabetes, Neimann urges.
Finally, keep up with your psoriasis treatment and treat flares when they occur. Doctors donâ€™t know yet if controlling psoriasis will help lower your chances of getting diabetes, but Neimann says thereâ€™s hope that future research will answer that question.
In the meantime, donâ€™t ignore the risks involved with psoriasis. Psoriasis is more than the rash on the surface of your skin â€” the effects of this disease can run deep in your body. But becoming aware of psoriasis complications means you can be proactive in protecting your health.
