Why Does My Period Wreak Havoc on My Blood Sugar?
If you're a woman living with diabetes or prediabetes, you may have noticed that your menstrual cycle can play havoc with your blood sugar levels. This is a common phenomenon, and there are several reasons why it happens. In this article, we'll explore the reasons behind this link and provide some tips on how to manage your blood sugar levels during your period.
Hormonal Changes During Menstruation
During menstruation, the levels of estrogen and progesterone in the body fluctuate. These hormonal changes can affect the body's insulin sensitivity, leading to higher blood sugar levels. Estrogen, in particular, can increase insulin resistance, making it harder for the body to use insulin effectively. This can lead to higher blood sugar levels, especially after meals.
Water Retention and Blood Sugar
Water retention is a common symptom of menstruation, and it can also impact blood sugar levels. When the body retains more water, it can lead to increased blood volume, which in turn can increase blood sugar levels. This is because the excess water in the bloodstream can dilute insulin, making it less effective at lowering blood sugar levels.
Stress and Blood Sugar
Menstruation can also cause stress, which is a known trigger for high blood sugar levels. Stress activates the body's "fight or flight" response, releasing hormones like adrenaline and cortisol, which can increase blood sugar levels. This is especially true if you're already experiencing high levels of stress due to work, family, or other responsibilities.

Tips for Managing Blood Sugar During Your Period
While it's challenging to completely eliminate the impact of menstruation on blood sugar levels, there are some strategies that can help:
- Monitor your blood sugar levels closely: Keep a close eye on your blood sugar levels during your period, and adjust your treatment plan as needed.
- Adjust your insulin dosage: You may need to adjust your insulin dosage to compensate for the hormonal changes and increased insulin resistance during your period.
- Stay hydrated: Drinking plenty of water can help reduce water retention and improve insulin sensitivity.
- Exercise regularly: Regular exercise can help improve insulin sensitivity and reduce stress levels.
- Manage stress: Engage in stress-reducing activities like yoga, meditation, or deep breathing exercises to help manage stress levels.
In conclusion, menstruation can have a significant impact on blood sugar levels due to hormonal changes, water retention, and stress. However, with close monitoring, adjustments to your treatment plan, and healthy lifestyle choices, you can manage your blood sugar levels and stay in control of your diabetes or prediabetes.
