“I called Family Sleep Diagnostics to schedule a sleep study in the Dallas area. From the person I spoke with on the phone before I even came, in to the night crew that carried out my sleep study, everyone I encountered was top of the line. Everything was clean, staff was nice and the pinnacle of professionalism.”

–  Nancy S. Dallas, TX

“I had a great experience with my sleep technologist. He answered all my questions before the study began and helped me understand what each device was monitoring. I felt so well taken care of that I had no problems falling asleep.”

Mark C. Fort Worth, TX

“I was given my own room with a comfy bed, TV, and private restroom. (I even took a shower!) My tech made me feel comfortable right away and really calmed my nerves. It was nice to see the same face waking me up in the morning, too.”

Ryan S. Addison, TX

Common Questions About Sleep

What causes sleep apnea?

Sleep apnea can occur if your airway becomes obstructed while you’re sleeping. In some cases, the tongue and throat muscles relax and block the windpipe. Structural issues, such as a large tongue or tonsils can increase your risk of developing the condition. People who are overweight are also at an increased risk of sleep apnea.

What are the symptoms of sleep apnea?

One of the main symptoms of sleep apnea is snoring. Although it’s important to understand, not all people who snore have sleep apnea. A bed partner may also notice your breathing periodically stops for brief periods of time through the night. Since people with sleep apnea have disrupted sleep, they often have excessive daytime  sleepiness may have morning headaches.

How do I know for sure if I have sleep apnea?

The best way to know for sure whether you have sleep apnea is to have a sleep study called a polysomnogram. During the study, a sleep technologist will monitor you while you sleep. When you arrive for your study, the tech hooks you up to various equipment, which monitors your brain activity, blood oxygen levels, heart rate and breathing patterns while you sleep. The results of the study help your doctor make an accurate diagnosis.
