Which condition is a differential diagnosis for insomnia in menopause?

• A. Allergic rhinitis
• B. Chronic cough
• C. Gastroesophageal reflux
• D. Sleep apnea

Answer: (D)

Insomnia in menopause is often linked to vasomotor symptoms, but a careful evaluation should also consider other sleep disorders that can mimic or worsen sleep troubles. Obstructive sleep apnea stands out as a key differential because it causes repeated awakenings and fragmented sleep, leading to nonrestorative sleep and daytime fatigue. This condition becomes more common with age and weight changes that occur around menopause, and women may present with less obvious signs like fatigue or morning headaches rather than loud snoring alone. So, when assessing insomnia in menopausal patients, you should actively screen for sleep apnea by asking about snoring, witnessed apneas, daytime sleepiness, and morning headaches. While factors such as allergic rhinitis, chronic cough, or GERD can also disturb sleep, sleep apnea is the most relevant differential to consider due to its prevalence in this group and its distinct impact on sleep quality and daytime function.
