One of the biggest concerns about diabetes is that it places people at higher risk for other health problems, including cardiovascular disease and kidney disease. However, there’s not as much awareness about the potential impact of diabetes on joint health.
Several members of DiabetesTeam have described having joint issues:
The overall prevalence of type 2 diabetes is between 2.4 percent and 14.8 percent of the general population, but this rate can be as high as 20.2 percent among people with psoriatic arthritis. Research into the connection is still ongoing. Here’s what’s currently known about why people with diabetes may be at an increased risk for developing psoriatic arthritis.
Psoriasis is an autoimmune condition that affects the skin. About 30 percent of people with psoriasis also develop inflammation in the joints, known as psoriatic arthritis. Psoriatic arthritis symptoms can appear at any time, but they most often occur about 10 years after psoriasis first develops.
Some common symptoms of psoriatic arthritis include:
People with psoriatic arthritis should meet with a rheumatologist to address their symptoms. Managing pain, reducing inflammation, and slowing joint damage are typically the primary goals of treatment.
Diabetes and psoriatic arthritis are both chronic diseases. There are two types of diabetes: type 1 and type 2. Psoriatic arthritis is typically associated with type 2 diabetes. The exact causes of the relationship are unknown, but researchers suspect several possible reasons for the higher rates of psoriatic arthritis in people with diabetes. These possible reasons include genetic factors, lifestyle factors, and inflammatory factors inside the body.
Sometimes psoriatic arthritis symptoms appear before other signs of psoriasis. If you notice joint pain, swelling, or stiffness, work with your health care provider to determine if psoriatic arthritis might be to blame.
A common risk factor for both diabetes and psoriatic arthritis is obesity, or high body mass index. Unfortunately, when you’re trying to stay active, joint pain and stiffness from psoriatic arthritis can complicate things. Decreased physical activity due to joint damage and pain can further contribute to issues with weight management, increasing the potential risk of diabetes. This cycle is challenging, but it doesn’t mean exercise is out of the question.
One member of DiabetesTeam suggests water aerobics as a low-impact activity. Ask your health care team about meeting with a physical therapist to develop an exercise routine that’s safe and effective for you.
Inflammation in the body may promote insulin resistance, even when people with psoriatic arthritis keep their weight at a healthy level.
Some studies suggest that people with psoriatic arthritis have elevated levels of tumor necrosis factor (TNF-alpha), a protein that contributes to inflammation in the body. Increased TNF-alpha levels may impair the function of insulin receptors. When insulin receptors in the body don’t work as well, the body may develop insulin resistance.
Increased inflammation can also lead to more severe psoriatic arthritis. Thinking of chronic inflammation as an underlying driver of multiple health problems (rather than a side effect of diabetes or psoriatic arthritis) can help you better manage both conditions.
People with psoriatic arthritis tend to have lower levels of certain biomarkers that normally enhance insulin sensitivity (help your body control blood sugar levels). Two examples are adiponectin and omentin. Lower levels of these biomarkers may increase the risk of diabetes.
Some research suggests that diabetes and psoriatic arthritis may share genes that make a person more susceptible to either or both health issues.
Some of the treatments prescribed for psoriatic arthritis may help people with diabetes, and others could make blood sugar issues worse. For example, when systemic corticosteroids are taken for long periods of time, they exacerbate insulin resistance. More research is needed to determine whether other medications such as Otezla (apremilast) and TNF-alpha inhibitors affect blood sugar control in a positive or neutral manner.
Knowing that poorly controlled blood glucose levels can exacerbate chronic inflammation and joint pain is a great incentive to keep up with your regular doctor’s appointments. Other approaches may also help you decrease your risk or better control the impact of your conditions on your quality of life.
Staying away from trigger foods that promote inflammation, including sugar, alcohol, and saturated fats, is important for both diabetes and arthritis.
Fortunately, the lifestyle changes that doctors recommend for diabetes prevention and treatment — including maintaining a healthy body weight and keeping stress to a minimum — can be beneficial for managing autoimmune diseases like psoriatic arthritis.
Losing excess weight, cutting back on refined sugars, increasing your fiber intake, getting more exercise, and improving your sleep habits can all help bring blood sugars back into the normal range and promote a healthy immune system.
Lifestyle changes and medication can go a long way toward improving your blood glucose levels and reducing arthritis symptoms. However, if excess body weight appears to be the underlying cause of multiple health issues (known as metabolic syndrome), bariatric surgery may also be recommended to improve your overall health and well-being.
Maintain good communication with your health care team when deciding on the best treatments. Depending on your family history and current blood sugar control, some psoriatic arthritis treatment options may be more appropriate than others. Ask your doctor or pharmacist about potential medication side effects, and discuss any concerns with your health care team.
