Missed More Often Than It Is Found
The stereotype — overweight, male, loud snorer — means sleep apnoea is routinely missed in women and in people of normal weight. Women more often present with insomnia, fatigue, morning headache, anxiety and non-restorative sleep than with witnessed apnoeas.
Narrow airways, jaw structure, nasal obstruction and tongue position all contribute independently of body weight.
What It Drives Downstream
Repeated overnight oxygen dips and arousals raise sympathetic drive and cortisol, worsen insulin resistance and blood pressure, suppress testosterone, and fragment the deep sleep in which repair happens.
That is why untreated apnoea quietly undermines work on hormones, metabolism and mood. It is one of the highest-yield things to rule out in a stalled case.
Testing and Next Steps
Home sleep testing has made assessment far more accessible, and wearable data showing overnight oxygen dips is a reasonable prompt to pursue formal testing. Diagnosis and treatment belong with a sleep physician.
Alongside that, nasal breathing, weight and body composition, alcohol timing, sleep position, and jaw and airway assessment all influence the picture.
