People with fibromyalgia have more difficulty falling asleep and sleeping less and better than the general population, according to the results of a new review. Researchers have called the attention of doctors on the treatment of sleep disorders in patients with fibromyalgia, because better sleep can help improve the symptoms of the disease..
The study, ” Interruption of sleep in fibromyalgia: a meta-analysis of case-control studies “, published in the Journal of Psychosomatic Research , reviewed several previously published studies that reported the contribution of sleep disorders in the development of fibromyalgia. .
The benefits of a good night’s sleep have a positive impact on everyone’s physical and mental health. But according to the researchers, poor sleep affects nearly 80% of patients with fibromyalgia, and studies have shown that poor sleep quality is a risk factor for fibromyalgia. In fact, a poor sleep is strongly associated with the severity of the symptoms: the fewer patients have to sleep, the more severe their symptoms are.
However, clinical studies with medications have shown that improving the quality of sleep can reduce pain in patients with fibromyalgia.
To understand the characteristics of sleep disorders and their effects on patients with fibromyalgia, the researchers examined 25 case-control studies with a total of 2,086 participants and assessed their sleep by polysomnography (19 studies) and Pittsburgh Sleep Quality Index (seven studies). .
Studies that evaluate sleep with polysomnography have reported significant differences between fibromyalgia patients and healthy people with respect to wakefulness after sleep onset, total sleep time and sleep efficiency among other parameters
Studies that evaluated sleep with the Pittsburgh Sleep Quality Index reported significant differences in overall scores, sleep onset latency, and sleep efficiency between the two groups of participants.
According to this study, patients with fibromyalgia have difficulty falling asleep, have poor sleep quality and sleep efficiency, longer wake-up time after sleep, shorter sleep duration and light sleep.
“Clinical trials have shown that improving sleep quality can reduce pain in people with fibromyalgia,” the researchers wrote. “Therefore, primary care providers should be informed by the results of this study and proactively assess the risk of sleep disorders in patients who complain of chronic widespread pain or consider the diagnosis of fibromyalgia in these patients. Physicians must also actively treat sleep disorders when low sleep is identified in people with fibromyalgia. “.
