The relationship between obesity and sleep apnea, particularly obstructive sleep apnea, has been well-established in medical literature. Obesity contributes to the development and exacerbation of obstructive sleep apnea due to the accumulation of excess fatty tissues around the neck and throat. This fatty tissue can increase airway resistance and lead to partial or complete obstruction of the airway during sleep. As a result, individuals with higher body mass indexes (BMIs) are at an increased risk of experiencing episodes of apnea, leading to disrupted sleep patterns and other associated health risks.

Weight reduction can indeed improve or even resolve obstructive sleep apnea symptoms in some individuals; however, it does not guarantee a complete cure for everyone, which underscores the need for ongoing management and treatment. Furthermore, sleep apnea can manifest in various ways beyond obesity, including other forms such as central sleep apnea, but the link between obesity and obstructive sleep apnea specifically is significant and well-documented.
