The Menstrual Cycle and Blood Glucose: Is there a Connection?

Oct 6. 2023

For many women, the menstrual cycle is a monthly occurrence that can bring about various changes and challenges. But did you know that it can also impact blood glucose levels? In this article, we will explore the connection between the menstrual cycle and blood glucose, and provide insights on how to manage your diabetes effectively throughout the different phases.

The Hormonal Influence:

Hormonal changes during the menstrual cycle, particularly estrogen and progesterone, can affect insulin sensitivity and how your body processes glucose. These hormones fluctuate throughout the cycle and can lead to notable changes in blood sugar levels.

The Follicular Phase:

During the follicular phase, which begins on the first day of your period, estrogen levels rise. This hormonal shift often results in increased insulin sensitivity, potentially causing blood glucose levels to decrease. It is important to monitor your levels consistently during this phase and adjust medication or insulin doses accordingly.

The Ovulatory Phase:

Around the middle of the menstrual cycle, ovulation occurs. This phase is marked by a surge in luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Some women may experience a rise in blood glucose levels during this time. Regular monitoring and maintaining a balanced diet can help keep glucose levels in check.

The Luteal Phase:

During the luteal phase, progesterone levels rise while estrogen levels decrease. This hormonal shift may lead to insulin resistance, resulting in higher blood glucose levels. It is crucial to maintain a consistent diabetes management routine and keep a close eye on your blood sugar readings during this phase.

Tips for Managing Blood Glucose During the Menstrual Cycle:

  • Keep a menstrual cycle diary: Tracking your menstrual cycle alongside blood glucose levels can help identify patterns and plan your diabetes management strategies accordingly.
  • Regular monitoring: Checking blood glucose levels regularly throughout the month can provide valuable insights into how your body responds to hormonal changes. This can help you adjust your treatment plan as needed.
  • Maintain a balanced diet: Opt for nutrient-dense foods, carefully considering carbohydrate intake, and distributing it evenly throughout the day. A well-balanced diet can help stabilize blood sugar levels during hormonal fluctuations.
  • Communicate with your healthcare team: Share any observations or concerns regarding your menstrual cycle and blood glucose patterns with your healthcare team. They can provide personalized guidance and support.


Understanding the connection between the menstrual cycle and blood glucose is essential for effective diabetes management in women. By being aware of the hormonal changes and their impact on insulin sensitivity, you can proactively adjust your diabetes management strategies throughout different phases.
