The side effects of hormones are the same effects experienced by people who produce this hormone naturally every day. For example:
- If you’re taking testosterone, then you have the risk profile and effects experienced by a person assigned male at birth (e.g. male pattern baldness, increased risk for heart disease or diabetes, slightly lower life expectancy, etc.)
- If you’re taking estrogen, you have the risk profile and effects experienced by a person assigned female at birth (e.g. increased risk of breast cancer and blood clots, change in weight distribution, etc.)
So, the “side effects” of hormone therapy are exactly the “effects” of hormones.
