Diabetes and periods 

Diabetes is a long-lasting condition affecting how your body uses glucose, while periods refer to the monthly menstrual cycle women experience. For women with diabetes, hormonal changes during menstruation can lead to changes in blood sugar, making it challenging to maintain stable glucose levels. 

These conditions can also lead to other complications, such as mood swings, fatigue, and depression. As a result, women with diabetes often face unique challenges when managing their menstrual cycle and blood sugar levels. 

Understanding the impact of menstrual hormones on blood sugar and vice versa is crucial for effective diabetes management. 

How do menstrual hormones affect blood sugar levels?

A week before a woman’s period, her hormones change, making her body less responsive to insulin. Insulin helps control blood sugar, but it doesn’t work as effectively during this time. When the period starts, blood sugar levels may decrease slightly.

How does diabetes affect the menstrual cycle?

There are several ways in which diabetes may have an impact on two things: blood sugar and menstrual cycle. Variations in blood sugar levels and insulin resistance can affect hormone levels, leading to irregular periods or, in some cases, a complete absence of periods altogether. Elevated blood sugar levels can disrupt the hormonal balance for a healthy, consistent menstrual cycle. Fluctuations in low blood sugar on period can lead to symptoms like fatigue and irritability.

Furthermore, women with diabetes may experience menstrual irregularities due to factors such as nerve damage or circulation problems that can affect reproductive organs. Therefore, these women must control their blood sugar levels to promote a healthy menstrual cycle. Women navigating diabetes and menstruation can benefit from open communication with healthcare providers to develop personalised care plans.

How does the menstrual cycle affect diabetes?

Changes in a woman’s hormonal levels during her menstrual cycle can impact the management of diabetes. During this time, fluctuations in blood sugar levels can be expected due to hormonal changes. It is common for women to experience higher blood sugar levels leading up to their period, which can be attributed to increased insulin resistance. 

On the other hand, when menstruation begins, blood sugar levels may drop, requiring adjustments in diabetes medication or insulin dosages to prevent low blood sugar (hypoglycemia) during the period.

What are the best ways to manage diabetes during the menstrual cycle?

Let’s look at the best ways to manage diabetes during your menstrual cycle.

1) Monitor your blood sugar levels closely

It is crucial to note your blood sugar levels consistently to detect any changes and adapt your diabetes care plan accordingly.

2) Adjust your insulin doses as needed

It’s essential to talk with your doctor to evaluate whether any modifications to your insulin dosage are required during your menstrual cycle. Increasing or decreasing your insulin intake may be necessary, depending on your blood sugar levels.

3) Eat a healthy diet

Maintain a well-rounded diet that includes various nutrient-dense edibles. Prioritise the consumption of carbohydrates, low-fat proteins, wholesome fats, and abundant fresh veggies. Avoid excessive indulgence in sugary edibles and beverages.

4) Exercise regularly

Engage in regular exercise as it helps improve insulin sensitivity and blood sugar control. Choose activities you enjoy and aim for aerobic exercise and strength training.

5) Reduce stress

The impact of stress on blood sugar should be considered. Exploring practical stress management techniques like indulging in hobbies, deep breathing exercises, meditation, or practising relaxation techniques to alleviate stress levels is wise. These activities can be highly effective in promoting a healthy lifestyle.

How can I prepare for insulin resistance during my menstrual cycle?

To prepare for insulin resistance during your menstrual cycle, follow these steps:

Step 1: Track your cycle

Maintaining a log of your menstrual cycle could be beneficial to detect trends and predict the onset of insulin resistance. Note the beginning and conclusion of your menstrual cycle and any symptoms before menstruation.

Step 2: Study your blood sugar pattern

Throughout your menstrual cycle, keeping a close watch on your blood sugar levels by taking blood sugar tests during periods and noting any fluctuations is crucial. Pay attention to any significant shifts or patterns in your readings.

Step 3: Adjust your insulin doses (with your doctor’s help)

Working closely with your doctor is essential to fine-tune your insulin doses according to your blood sugar patterns. By engaging in a collaborative approach with your healthcare provider, you can gain the necessary insights required to make informed decisions about any alterations that may need to be made to your insulin regimen.

What to eat for better blood sugar balance during the period?

Focusing on a healthy and well-balanced diet is essential to maintain your blood sugar during your period. Here are some dietary tips:

What to eat for better blood sugar balance during the period
  • Choose complex carbohydrates: Consider incorporating whole grains such as brown rice, wheat bread, and quinoa into your diet. These carbohydrates are abundant in fibre and can effectively assist in controlling blood sugar levels.
  • Include protein: Eating foods that are high in protein, like lean meats, poultry, fish, beans, lentils, and tofu, can help in stabilising blood glucose levels and sustaining energy throughout the day.
  • Add healthy fats: Healthy fats can do wonders for your health. Consider incorporating sources like avocados, nuts, seeds, and olive oil, as they can help regulate blood sugar levels and slow down carbohydrate digestion. It’s a simple and effective way to improve your overall well-being.
  • Eat fibre-rich foods: Including a diverse range of fruits, vegetables, and legumes in your daily dietary routine can positively impact your overall health. These foods are all fibre-rich, which can facilitate the digestive process and assist in maintaining stable blood sugar levels.
  • Avoid sugary foods and refined carbohydrates: It is advisable to limit the intake of sugary snacks, candies, sodas, and foods that are rich in white flour, as they can lead to a sudden increase in blood sugar levels.
  • Stay hydrated: Consuming adequate water throughout the day is vital for maintaining proper hydration levels and promoting optimal health.


Women need to understand that low blood sugar during a period is not a diabetic condition, nor do high blood sugar. If you already have diabetes, these changes in sugar levels might happen.

Managing diabetes and periods can be challenging, but it’s important to remember that navigating these challenges with the right strategies and support is possible. Understanding the interplay between diabetes and menstruation is crucial for maintaining overall well-being in women with diabetes.

Regular check-ups with healthcare professionals can help identify potential issues early on, and implementing healthy habits such as regular exercise and a well-rounded diet can also help manage symptoms. By taking proactive steps and staying informed, women can manage both their diabetes and menstruation to live a healthy and fulfilling life.
