Internal Medicine

Common sleep disorders in adults include insomnia, sleep apnea, restless legs syndrome (RLS), and narcolepsy. Insomnia involves difficulty falling or staying asleep, while sleep apnea causes breathing interruptions during sleep. RLS triggers uncomfortable leg sensations, and narcolepsy leads to sudden daytime sleep episodes. Each condition can significantly impact sleep quality, energy levels, mental focus, and long-term health.

If you're experiencing symptoms like poor sleep, daytime fatigue, or unusual sensations at night, identifying the cause early is key to effective treatment. Take a free, instant, online symptom check to better understand what may be affecting your sleep and get clear guidance on your next steps—no appointment needed.

Explanation

Sleep disorders can make it hard for adults to get a good night's sleep. Here are some common types:

Insomnia: This is when you have trouble falling asleep or staying asleep. It can make you feel tired during the day.
Sleep Apnea: This happens when your breathing stops and starts while you sleep. It can make you feel very sleepy during the day.
Restless Legs Syndrome (RLS): This is a strong urge to move your legs, often with strange feelings in your legs. It can make it hard to fall asleep.
Narcolepsy: This is when you suddenly feel very sleepy during the day and might fall asleep suddenly.
