My clinic, Newson Health, sees thousands of patients every year, which allows us to collect a huge amount of data about menopause symptoms and the response to various treatments.
In a recent audit of over 300 patients, we looked at oestrogen doses and blood oestradiol levels, and menopause symptoms scores for each woman. A lower score indicated fewer or milder symptoms, a higher score indicated a greater number or more severe symptoms.
Although there was a correlation between oestrogen dose and blood levels of Oestradiol, there was no statistical relationship between Oestradiol levels and Menopause Symptom Questionnaire (MSQ) scores. This was initially surprising, because one might expect that higher levels of circulating oestrogen was related to women experiencing fewer symptoms and feeling better.
These results tally with my clinical impression from having spoken to thousands of women over the course of several decades. Very often, when I see patients for their follow-up appointment, they have had some improvements in certain symptoms, whilst other symptoms remain. In these cases, we often adjust HRT levels to optimise symptom response.
In the study we carried out, the 50 patients prescribed the highest doses of oestrogen had an average oestradiol level of 921 and, on average, their symptom score was 20. However, in the 50 women with the lowest oestradiol serum level (average 113), their average symptom score was 24.
If you’ve followed me for a while, you’ll have heard me say countless times that HRT is not one-size-fits-all and these findings really back that up: some women need higher doses of oestrogen to see an improvement in their symptoms.
