Sleep Apnea

Comprehensive sleep apnea evaluation, home sleep testing, and CPAP management to protect your breathing, energy, and long-term cardiovascular health — from pulmonary specialists at Remix Medical in Houston, TX.

Sleep apnea is a dangerous sleep disorder that interferes with healthy breathing patterns during sleep. It is characterized by snoring, which may be so loud that it affects the sleep quality of bed partners. Having sleep apnea can put a strain on relationships, cause daytime fatigue, and even lead to other secondary conditions like depression. Worse, severe cases of sleep apnea can be life threatening.

Though snoring is a primary symptom of sleep apnea, not all people who snore actually have sleep apnea. As much as 50 percent of Americans snore at some time, whether occasionally or chronically. However, only 20 percent of American adults have sleep apnea. Harmless snoring does not interfere with breathing patterns. Sleep apnea, on the other hand, causes breathing cessations and sometimes "gasping" during sleep.

Do I Need Treatment For Sleep Apnea?

You may need to see a doctor if you or your partner have been awakened by chronic snoring and/or gasping for air. Though this condition can be very dangerous, your doctor can help you discover ways of managing sleep apnea and protecting healthy breathing during sleep.

How Will My Doctor Screen For Sleep Apnea?

Your doctor's first goal will be to determine whether your snoring is benign or a symptom of sleep apnea. This may be determined by speaking with you and your partner about your symptoms. If you do not have a partner who can confirm snoring or breathing interruptions, your doctor may request a sleep study.

What Types Of Treatments Are Available?

There are many ways of treating the symptoms of sleep apnea. This may include conservative approaches, such as a new sleeping position or the use of an oral appliance. If your apnea symptoms are severe or conservative treatments are not working, you may be prescribed a continuous positive airway pressure device (CPAP) to open the airway. In severe cases, surgery may be necessary. Many patients find that losing weight can be an effective way of opening the airway during sleep.

ApproachWhat it involves
CPAPThe gold standard — gentle air pressure keeps the airway open
Oral applianceA custom mouthpiece for milder cases
Weight + lifestyleWeight loss, side-sleeping, avoiding alcohol before bed
SurgeryFor specific anatomical causes when other options fail

Frequently asked

Sleep Apnea questions, answered

What are the signs of sleep apnea?

Loud snoring, gasping or choking awake, morning headaches, and daytime sleepiness are the classic signs. A partner noticing pauses in your breathing is a big clue.

How is sleep apnea diagnosed?

With a sleep study, which can often be done at home. It measures your breathing and oxygen levels overnight to confirm the diagnosis and its severity.

Is sleep apnea dangerous?

Untreated, it raises the risk of high blood pressure, heart disease, stroke, and accidents from daytime drowsiness. Treating it improves both health and quality of life.

What is the best treatment for sleep apnea?

CPAP, which keeps the airway open with gentle air pressure, is the gold standard. Oral appliances, weight loss, and side-sleeping help milder cases, and surgery is an option for specific causes.

Can sleep apnea affect my kidneys and blood pressure?

Yes. Untreated apnea drives up overnight blood pressure and is linked to faster kidney decline, which is why treating it matters for people with kidney disease or stubborn hypertension.
