How Restless Leg Syndrome and Sleep Apnea Overlap—and What Helps
Restless Leg Syndrome (RLS) and Obstructive Sleep Apnea (OSA) are two common sleep disorders that often overlap. Both conditions tend to worsen with age and share several risk factors. While no direct causation has been proven, some people experience both at the same time.
RLS and OSA affect many people, particularly as they grow older. Risk factors for both include obesity, type 2 diabetes, Parkinson’s disease, high blood pressure, congestive heart failure, and chronic obstructive pulmonary disease. A family history of either condition also increases the likelihood of developing them.
Some studies suggest that poor oxygen flow in the legs may contribute to RLS. Though no clear link has been established between the two disorders, they sometimes appear together in the same person.
Treatment options for OSA include CPAP machines, oral appliances, upper airway stimulation, surgery, and iron supplements. A CPAP device, which improves breathing during sleep, may also ease RLS symptoms. For RLS, doctors often recommend iron supplements, dopamine-boosting medications, anticonvulsants, or benzodiazepines.
Both conditions can be managed with lifestyle changes. Better diet and exercise, quitting smoking, avoiding dietary triggers, and improving sleep hygiene are recommended for those affected.
The US Department of Veterans Affairs (VA) recognises the serious impact of RLS and OSA on daily life. Disability benefits are available based on the severity of each condition.
While research continues into the possible connection between RLS and sleep apnea, treatments already exist to help manage symptoms. The VA provides support for veterans affected by these disorders, acknowledging their significant effects on health. Lifestyle adjustments and medical interventions remain key in improving quality of life for those diagnosed.
