Do you snore? Have you gained weight? Do you get up and urinate at night? Is it often at a similar time? Are you sometimes aware of waking from a dream during the night? These are all common symptoms in people with Obstructive Sleep Apnea. Over time, blood pressure may start to go up, and/or blood sugar levels (diabetes), reflux during sleep is another symptom. If you have trouble getting hour legs comfortable or have an urge to move them, or wake with leg cramps, you may have Restless Legs and/or Periodic Limb movements - nobody knows they have that without a sleep study, sometimes a bed partner will say the person looks like they are riding a bike in their sleep. People can have one or both OSA and RLS PLMD. A sleep study is the best way to figure it out, in the sleep center if possible. Home screening studies tend to under estimate apnea and can’t detect the periodic limb movements or what is happening either the sleep stages - not good for evaluating insomnia. Meds won’t control your problem if the cause of the problem hasn’t been identified, so the correct treatment can be chosen.
I hope this helps.
