I have been aware of many posts advising changes in dose of estrogen. There are many factors to consider before increasing the dose, including practical aspects such as if using patches, are they staying on ok or causing skin irritation, which can affect absorption. Where are you applying the patches?--buttocks are believed to be the site for best absorption. Are symptoms purely hormone related, or are other factors contributing including nutritional factors, stress and lifestyle. Has a daily tablet been considered as an option, which suits many women well with minimal risk. Any possible change in regimen should be discussed with your doctor or nurse.
If after all this is considered and it is agreed that an increase in dose of estrogen is needed, then the progestogen used should be also increased proportionately. There is less chance of abnormal bleeding with HRT, which causes concerns and often uncomfortable investigations, when using HRT preparations that combine both estrogen and progestogen proportionately, eg a combined patch or combined tablet, rather than taking them separately. Please take all this into consideration.
