Why your 'noisy' sleep could be a sign of obstructive sleep apnea

Frequent snoring, often dismissed as a mere nocturnal annoyance, may be a critical indicator of underlying cardiovascular and metabolic risks.

Dr Nikhil Yadav, a senior surgeon at Manipal Hospital, warns that persistent snoring and unrefreshing rest are frequently the first signs of obesity-related obstructive sleep apnea (OSA).

This condition involves the repetitive cessation of breathing during sleep, caused by the physical collapse of the airway.

In individuals living with obesity, fat deposits around the neck compress the upper respiratory tract, significantly restricting airflow.

The physiological impact of these interruptions is profound. Dr Yadav explained that with each pause, oxygen levels briefly reduce, which fragments sleep, and leads to fatigue, morning headaches and difficulty concentrating during the day.

Furthermore, even modest weight gain can disproportionately escalate these risks. “The extra body weight has a compressing effect on the throat area, more so when a person is lying on his/her back. Obesity also reduces lung volume and alters breathing control, making airway collapse during sleep more likely,” he added.

Dr Yadav identified several early warning signs that often go unrecognised:

• Loud, frequent snoring and gasping during sleep.
• Poor sleep quality despite spending many hours in bed.
• Morning headaches, chronic fatigue, and mood changes.

If left unaddressed, OSA creates a dangerous cycle; poor sleep disrupts insulin function and appetite control, making weight loss increasingly difficult.

The long-term consequences are severe, as “persistent snoring and unrefreshing sleep are common early indicators of obesity-related obstructive sleep apnea (OSA),” potentially leading to hypertension, heart disease, and stroke.
