Researchers have found another link between the poorly understood disease fibromyalgia and vitamin D.
About 5 million Americans suffer from fibromyalgia, according to the Department of Health and Human Services. Most of the people who have the disease are women and most develop symptoms in middle age. Symptoms include chronic pain and fatigue along with sleep disorders, morning stiffness, poor concentration and occasionally mild-to-severe mental symptoms like anxiety and depression. There is no cure.
In 2014, researchers in Vienna reported that for patients with fibromyalgia syndrome (FMS) with low vitamin D levels, vitamin D supplementation reduced their pain. The subjects’ “marked reduction in the level of perceived pain” continued even 24 weeks after they stopped receiving the vitamin D supplements. That study was published in the journal PAIN.
The recent research from last year, a meta-analysis of existing studies, was published in the journal Pain Physician. Researchers at the National Taiwan University Hospital analyzed data from over 1,800 fibromyalgia patients with chronic and widespread pain. They found they all had low levels of vitamin D.
What’s not clear, however, is whether the low levels of the vitamin are the cause of, or the result, of the disease, according to a story about the research on painnewsnetwork.com.
