What should you know about perimenopause and type 1 diabetes?
Perimenopause is the transition phase before menopause when your body starts producing less estrogen and progesterone. These hormone levels fluctuate, which can significantly affect blood sugar management if you have type 1 diabetes.
During perimenopause, you might experience:
- Irregular menstrual periods
- Hot flashes and night sweats
- Vaginal dryness
- Frequent need to urinate
- Sleep problems
- Mood changes
This phase typically begins in your mid-40s and lasts about seven years.
The hormonal changes during perimenopause can make managing type 1 diabetes more challenging. Estrogen helps increase insulin sensitivity, so as levels fluctuate, your blood sugar may become harder to control. You might notice your sugars are "out of whack" even if you've been managing well for years.
A myT1Dteam member shared: "I hit perimenopause about two years ago, and this year my sugars have been uncharacteristically out of whack."
Weight gain and sleep problems common during perimenopause can also affect insulin resistance and blood sugar levels. Additionally, some perimenopause symptoms like hot flashes and irregular heartbeats can mimic low blood sugar symptoms, making it important to check your levels regularly.
You may need to adjust your insulin-to-carbohydrate ratios and monitor your blood sugar more frequently during this time. Talk with your healthcare team about managing these changes.
