Blood sugar elevations aren't commonly highlighted as a primary side effect of tamoxifen or letrozole in the available research, but it's a great question to bring up with your oncology team, as everyone's body responds differently to these medications.
Both tamoxifen and letrozole can cause a range of side effects that may indirectly affect metabolism, including weight changes, which can influence blood sugar levels. Here are some known side effects of these medications that could be connected to blood sugar changes:
- Weight gain — reported with both tamoxifen and letrozole, which can affect blood sugar regulation
- Appetite changes — letrozole can increase cravings, as one MyBCTeam member noted craving sweets and pastries
- Hormonal shifts — tamoxifen may affect thyroid function in the first year, which can influence metabolism
It's really important to flag any blood sugar concerns with your doctor. They can run tests to identify what's going on and help you manage it effectively. Keeping your whole care team in the loop is always the best move.

Yes. In the beginning when aI started letrozole. I gained weight, blood sugar went up, not a lot but it still went up. My chlorestrol increased as well. Everything is normal now but we still check it all every 6 months. Wishing you the very best
