Weight & Sleep

Sleep Apnea and Obesity

Weight and sleep apnea are tightly linked, and the relationship runs both ways. Understanding the cycle is the first step to breaking it.

How weight contributes to sleep apnea

Excess weight, especially around the neck and upper airway, can narrow or crowd the airway so it collapses more easily during sleep. That's why obesity is one of the strongest risk factors for obstructive sleep apnea.

How poor sleep contributes to weight gain

The cycle runs in reverse, too. Fragmented sleep shifts the hormones that regulate appetite — raising ghrelin (hunger) and lowering leptin (fullness) — which can increase cravings and make weight harder to manage.

Breaking the cycle

Because each condition worsens the other, treating both together is often the most effective approach. That can include sleep apnea treatment alongside physician-guided weight management. It starts with a diagnosis — see home sleep apnea testing.
