I’m FINALLY addressing the age old question: “Does estrogen therapy cause weight gain?” 👀
The short answer is yes & no… but let me explain what’s actually happening!
Estrogen therapy may cause some initial “weight gain,” but this isn’t fat gain! Estrogen is an incredibly hydrating hormone, which will commonly cause water retention, and that’s actually what gives it a bad rap. 🫠
But that same hydrating effect is exactly why estrogen is so protective for your joints, your heart, your brain, your skin, and your overall health. So the initial water retention you experience when starting estrogen therapy? That’s actually a really good sign that your body is responding. 🤌🏻
Some degree of water retention is pretty much inevitable, but it is absolutely manageable! And this is exactly why getting your progesterone dose dialed in is so important (regardless of whether or not you have a uterus). Progesterone helps offset any unwanted side effects you may be experiencing from estrogen, including fluid retention.
The weight fluctuation can feel uncomfortable, and that’s completely valid. But try to remember what that hydration is actually doing for your body behind the scenes. 🫶🏻
