Final answer:
Treatment of obstructive sleep apnea can decrease snoring, daytime sleepiness, and heart disease risk, representing all the options listed.
Step-by-step explanation:
Treatment of obstructive sleep apnea decreases snoring, daytime sleepiness, and may also contribute to a reduction in the risk of developing or exacerbating heart disease. Therefore, the correct answer is 4) All of the above. The use of a CPAP (continuous positive airway pressure) machine at night is a common treatment, which helps to keep the throat open and allows for normal breathing during sleep.
Additionally, lifestyle changes like losing weight, avoiding alcohol, quitting smoking, and altering sleep positions, as well as using certain oral devices and, in more severe cases, surgery, can also be effective treatments. These interventions can significantly improve the quality of life for individuals with sleep apnea and mitigate the risks associated with the disorder.
