Can hypothyroid cause joint pain?
Psoriasis and psoriatic arthritis are both autoimmune disorders: They result from the immune system mistakenly attacking the body. Another autoimmune disorder, Hashimoto’s thyroiditis, can cause hypothyroidism.
Psoriatic joint pain and hypothyroidism: Would they say they are connected?
Doctors and researchers believe that a person with one autoimmune condition, such as psoriasis or psoriatic arthritis, may have a higher likelihood of developing another autoimmune condition, such as Hashimoto’s thyroiditis.
Also known as Hashimoto’s disease, this condition causes the immune system to attack the thyroid gland, preventing it from making enough thyroid hormone. “Hypothyroidism” refers to having too little thyroid hormone in the body.
Below, learn more about the relationship between these autoimmune disorders.
Overview of the conditions
Psoriasis is an autoimmune disorder that causes scaly, itchy patches of skin to form around a person’s trunk, large joints, and other areas of the body. It affects about 2–4%Trusted Source of the population.
Psoriatic arthritis is a type of arthritis that can occur in people with psoriasis. About 30%Trusted Source of people with psoriasis also develop this form of arthritis. It is not possible to have psoriatic arthritis without psoriasis.
This inflammatory type of arthritis causes symptoms such as joint pain, swelling, and stiffness. If a person does not receive treatment, psoriatic arthritis can eventually lead to joint damage and mobility issues.
Hypothyroidism occurs when the thyroid gland does not make enough thyroid hormone to meet the body’s needs. The body uses this hormone to keep the brain, heart, and muscles functioning correctly. It also helps the body effectively burn calories for energy and warmth.
There are various causes of hypothyroidism, including Hashimoto’s disease, surgical removal of the thyroid gland, and other treatments for other health issues.
Are psoriasis and thyroid issues linked?
Hypothyroidism is not closely associated with psoriasis generally or psoriatic arthritis in particular. However, research indicates that a person with psoriasis may have a higher chance of developing hypothyroidism.
A 2017 study Trusted Source found that people with both psoriasis and psoriatic arthritis had a higher likelihood of developing this thyroid condition.
Another study from 2017 and one from 2018 found similar results: People with psoriasis had a higher likelihood of developing thyroid disease, such as hypothyroidism, compared with the general population.
Also, a 2019 review of studies Trusted Source found that people with psoriasis had a much higher prevalence of Hashimoto’s disease than those without psoriasis.
While there is a need for more studies with more participants, many researchers currently recommended that doctors regularly screen people with psoriasis for thyroid conditions.
