If you're considering hormone replacement therapy (HRT) or have just started it, it's important to know what effects to expect and when they will occur. The first changes you'll likely notice are that your skin will become a little drier and thinner. Your pores will get smaller and there will be less oil production. You may become more likely to get bruises or cuts, and in the first few weeks, you'll notice that the smells of sweat and urine will change.
Many women will begin to experience some relief from symptoms in the first two weeks. Hot flashes, night sweats, and trouble sleeping are the main symptoms that get better right away. These tend to continue to improve over time. Any abnormal or unexpected bleeding (even minor spotting) that occurs after you have decided on hormone replacement therapy in advance should be reported to the general practitioner.
It is also important to understand which symptoms are the most worrying and what are the expectations of each woman with respect to HRT. If you're just starting hormone therapy, the process can start now and you'll likely see the first results in a few weeks.
