Can obesity cause obstructive sleep apnoea?

In obstructive sleep apnoea, the upper airway repeatedly narrows or closes while a person is asleep. The brain may briefly wake the person to reopen it, so sleep becomes fragmented even when the awakenings are not remembered. Loud snoring, witnessed pauses in breathing, gasping, morning headaches and daytime sleepiness are common clues. Obesity is one contributor, but jaw shape, enlarged tonsils, nasal blockage, alcohol, sedating medicines and family tendency can also matter. A sleep assessment is needed to confirm the diagnosis.

Tell a clinician if someone notices breathing pauses or if you feel sleepy while driving or working. They may arrange a home or clinic sleep study and discuss treatment such as positive airway pressure, an oral appliance or other options. Side-sleeping, treating nasal congestion, limiting alcohol near bedtime and reviewing sedating medicines may help. Weight-management support can reduce airway pressure for some people, but prescribed treatment should not be stopped without advice.

Seek prompt assessment for repeated breathing pauses, severe daytime sleepiness or near-misses while driving. Get urgent help for breathing difficulty while awake, blue lips, fainting, chest pain or confusion. Untreated sleep apnoea can affect alertness and health, so persistent snoring with witnessed pauses deserves medical attention.

Could my snoring and tiredness indicate sleep apnoea? Should I have a sleep study? Which treatment fits my airway, sleep pattern and daily routine? Is it safe for me to drive until this is assessed?
