Can hormone therapy make migraines worse?
Some new research presented at The Menopause Society’s annual meeting in San Diego raises an interesting question about hormone therapy and migraines.
Researchers looked at five studies involving nearly 24,000 postmenopausal women. They found that women using hormone therapy tended to have more frequent migraines, and those migraines lasted longer. However, the researchers didn’t find a significant difference in how severe the migraines were or how much pain medication women used.
So what does this mean if you’re considering hormone therapy?
First, this research doesn’t prove that hormone therapy causes migraines. We already know that changes in estrogen levels can affect headaches, particularly during perimenopause, when hormone levels can fluctuate quite a bit.
Hormone therapy is still one of the most effective treatments we have for hot flashes and night sweats. Having migraines doesn’t automatically mean you can’t use it.
What matters is looking at your symptoms, your medical history, and which treatment makes the most sense for you. The type of hormone therapy and how it’s delivered may also make a difference.
If you’re dealing with migraines around menopause, I would suggest keeping track of when they occur, how long they last, and whether you’ve noticed any changes since starting treatment. That’s useful information to bring to your healthcare provider.
The goal is to treat your menopause symptoms without overlooking other health concerns.
