At 32, can I breastfeed with my type 2 diabetes?

Question

Hello doctor,

I am a 32 year old woman recently diagnosed with type 2 diabetes. My fasting sugar is 148 mg/dL, HbA1c is 7.2%, and I have gained weight after pregnancy last year. I am breastfeeding my 10 month old baby and on Metformin 500 mg twice daily. My periods have been irregular lately, and sometimes I feel dizzy before they start. My mother also has diabetes, so I’m worried about long-term risks. Please tell me,

Is it safe during breastfeeding?
Can this condition affect my chances of having another baby in the future or cause complications like PCOS or hormonal imbalance?
Could this be related to blood sugar changes?
Is it true that stress and lack of sleep from night feeding can worsen glucose control?
How can I manage my diet without affecting my milk supply?

Kindly help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Your fasting glucose level is 162 mg/dL, and your glycated hemoglobin (HbA1c) is 7.2%, which are consistent with uncontrolled Type 2 Diabetes. Starting Metformin 1000 mg twice daily is appropriate because it improves insulin sensitivity, supports weight control, and may also help address menstrual irregularity if insulin resistance is contributing to your symptoms.

During perimenopause, estrogen levels fluctuate, which can increase insulin resistance and make blood sugar more difficult to control. Hormonal changes can also promote

Abdominal weight gain.
Worsen fatigue.
Mood swings.
Hot flashes.
Sleep disturbance.

At the same time, uncontrolled blood sugar can make menopausal symptoms such as hot flashes, night sweats, and tiredness more severe. This means that diabetes and perimenopause can significantly influence each other.

Hormone Replacement Therapy can be safe and beneficial for some women with diabetes when it is carefully selected and monitored by a specialist. It may help improve hot flashes, mood, sleep quality, and bone health. Certain forms, especially transdermal estrogen, may also improve insulin resistance and lipid profile.

You should consult an endocrinologist for further evaluation and long term treatment planning. You should also start regular blood sugar monitoring. You should check your blood sugar before breakfast, after meals, before dinner, and after dinner. Ideally, your fasting blood sugar should remain close to 100 mg/dL, and your postprandial blood sugar should remain around 140 mg/dL.

Lifestyle management is also very important. You should follow a

Diabetic friendly diet.
Reduce excess sugar.
Refined carbohydrates.
Maintain regular physical activity.
Work on gradual weight control if needed.

For irregular bleeding, you can start a tablet containing Cyproterone acetate/ethinylestradiol, one tablet at night for 21 days followed by a 7 day pill free interval, and continue this cycle for 3 months. However, because hormonal medications may not be suitable for everyone, especially in women with diabetes or cardiovascular risk factors, you should use them only after discussing them with your gynecologist.

I hope this information helps you.
