Assessment:
Likely diagnosis of Obstructive Sleep Apnoea (OSA) given the classic symptoms of loud snoring, witnessed apnoeas, and significant daytime sleepiness, exacerbated by obesity and thick neck. Differential diagnoses include central sleep apnoea (less likely given loud snoring) and restless legs syndrome (no symptoms reported).
Plan:
Discussion regarding lifestyle modifications including weight loss, regular exercise, and avoiding alcohol before bed. Referral to a sleep clinic for polysomnography (sleep study) to confirm diagnosis and determine severity. Advised on nasal strips and positional therapy as temporary measures. Reviewed risks of untreated OSA including cardiovascular complications.
