Vasomotor symptoms, mainly in the form of hot flashes, are the most commonly reported menopausal symptom. While many people assumed a connection, data was inconsistant, it was only recently that cross sectional survey using the Menopause Health Questionnaire from Mayo Clinic was conducted that compared users and non-users of caffeine beverages. A total of 2,507 surveys were completed and after adjusting for menopause status and smoking (caffeine users smoked more than non-users), the researchers found that caffeine users reportied higher vasomotor symptom scores.
There was some evidence of a decrease in neurocognitive symptom bother in premenopausal (not post menopausal women) with caffeine use but more study is need to determine if this is true. Interestingly, other menopausal symptoms (sleep, blowel/bladder function, sexual function, and general/other symptoms) did not show an association with caffeine use.
