Sleep Studies in Houston: Better Sleep for Better Health

At CLS Health, our sleep medicine specialists are dedicated to helping patients overcome sleep problems and sleep disorders. Good health depends not only on getting enough sleep but also on the quality of sleep. 

Sleep disorders can increase the risk of accidents, headaches, difficulty concentrating, depression, anxiety, weight gain, high blood pressure, heart disease, and diabetes. A sleep specialist can help identify the root cause and guide you toward lasting relief.

How Sleep Disorders Are Diagnosed

Our sleep doctors in Houston and Webster start with a careful review of your health and sleep history. Your treatment will depend on the type and severity of your disorder. Sometimes, an underlying medical condition is responsible for poor sleep and treating it can restore restful nights. 

When needed, we may recommend a sleep study in Houston or Webster (polysomnography or home sleep apnea testing) to confirm your diagnosis. Even mild sleep disorders can significantly affect your quality of life, but early diagnosis leads to better outcomes.
