Internal Medicine

Waking up in the middle of the night is often caused by stress, anxiety, or underlying medical conditions such as sleep apnea, acid reflux, hormonal changes, or restless leg syndrome. Disruptions to your natural sleep cycle—like irregular schedules, alcohol, caffeine, or blue light exposure—can also fragment sleep and make it harder to stay asleep through the night.

Because nighttime waking can stem from many different causes, identifying the root issue is the fastest way to find relief. Take a free, instant, online symptom check to better understand what may be behind your disrupted sleep and get clear guidance on your next steps.
