Like any other procedure, there are things that show you may well need to be tested for sleep apnea. What are the indications that you should be tested? The three main reasons to speak to your Dr about having a test are listed below

1. Old people. The people who are old are at risk of developing different kinds of apnea. The test may help in establishing an early diagnosis. If an early diagnosis is established, prompt treatment can be given.
2. Obese people. Those who are heavier than the required weight for their height are candidates of sleep apnea. It has something to do with how the fat affects their muscle tone.
3. People who manifest some suggestive signs and symptoms. One remarkable thing to note in people who are suspected to have sleep apnea is loud snore. Although not a definitive manifestation, the loud snoring will help the person decide to undergo the test.
