If you live with diabetes and are planning a pregnancy, you have probably asked the same question quietly: will this make it harder for us? The honest answer is that it can, but it is far from a closed door. Many women and men with well-managed diabetes conceive naturally. To understand where you stand, you can request your Fertility assessment score, speak to our dietitian, or view our pricing. This guide explains what diabetes changes, what blood sugar control can realistically do, and what to prepare before you try.
Quick answer: Can diabetes make it hard to conceive?
Yes, it can. Poorly controlled diabetes may disrupt ovulation, reduce sperm quality and raise miscarriage and pregnancy risks. However, many people with diabetes conceive naturally, and improving blood sugar, ideally to an HbA1c near the range your doctor advises before conception, supports both fertility and a safer pregnancy. Nutrition works alongside your medical care, not instead of it.
From our clients: "I conceived naturally after nearly two decades"
"At 40, after struggling with sugar issues for years, I had accepted that my journey of motherhood was over. 19 years had passed since my second child… and I never thought I'd conceive again. But thanks to the guidance, care, and diet plan from the Health Hatch team, everything changed. My health improved, my sugar levels stabilized… and today, I'm blessed to say I conceived naturally after nearly two decades." Shabana T., age 40 | Google review (5 stars)
Her situation: Years of blood sugar problems, and 19 years since her last pregnancy. Our focus: A personalised diet plan to stabilise blood sugar and improve overall health, alongside her medical care. Outcome: Her sugar levels stabilised, and she conceived naturally.
This is one client's own experience. Individual outcomes vary, many factors influence conception, and this is not a guarantee. Shared from a public Google review.

How can diabetes make it hard to conceive?
Diabetes affects fertility through hormones, blood vessels and metabolism, and the effect depends on the type, how long you have had it and how well it is controlled.
In women:
- Ovulation: Insulin resistance raises insulin and androgen levels, which can lead to irregular or absent ovulation. This is why type 2 diabetes and PCOS so often overlap. Type 1 diabetes is also associated with menstrual irregularity, particularly when control is poor.
- Egg and embryo environment: Sustained high glucose creates oxidative stress, and elevated glucose around conception is linked to higher miscarriage risk.
- Weight and metabolic factors: Central weight gain and fatty liver, common in type 2 diabetes, further disturb hormones.
- Time: Delays in diagnosis or management can mean months or years of unrecognised metabolic stress.
In men:
- High glucose is associated with lower semen quality, including reduced motility and greater sperm DNA damage in some studies.
- Diabetes can contribute to erectile dysfunction and, less commonly, retrograde ejaculation.
- Low testosterone is more common in men with type 2 diabetes and obesity.
For both: Poorly controlled diabetes raises the risk of complications during pregnancy, including congenital anomalies, preeclampsia and large-baby delivery. This is why preparation matters as much as conception itself.
Practical takeaway: Diabetes does not mean you cannot conceive. It means that the months before conception are an opportunity to shape both your chances and your pregnancy's safety.
Can controlling blood sugar help you conceive naturally?
For many people, yes, it supports it meaningfully, though no one can promise an outcome.
Lower and steadier glucose can reduce insulin resistance, which helps restore more regular ovulation, particularly in women with type 2 diabetes or PCOS. In men, improving glycaemic control and metabolic health may support semen parameters, although the evidence is still developing. Importantly, stable blood sugar before and during early pregnancy lowers the risk of miscarriage and birth defects.
Major guidelines, including those from the American Diabetes Association, advise planning pregnancy and aiming for an HbA1c as close to normal as can be safely achieved, generally below 6.5%, before conception, without frequent low blood sugars. Your own target should be set by your doctor. HbA1c reflects about three months of glucose, so a realistic preparation window is three months or more.
What nutrition cannot do: It cannot cure infertility or guarantee pregnancy, and it does not replace fertility evaluation, medication or treatment such as IUI or IVF if needed. It addresses the part of the picture that is modifiable: glucose, insulin sensitivity, nutrient adequacy, weight distribution and lifestyle.
Practical takeaway: Think of three months of structured blood sugar work as preparing the ground, for fertility and for a safer pregnancy.
What foods can you include when you have diabetes and are trying to conceive?
The goal is to flatten glucose spikes while meeting the higher nutrient needs of preconception. Rather than cutting out entire food groups, build balanced plates.
| Food group | Good choices | Why it helps |
|---|---|---|
| Fibre-rich carbohydrates | Millets, whole wheat roti, oats, red or brown rice, quinoa (in measured portions) | Slower glucose rise |
| Protein | Dal, chana, rajma, paneer, eggs, tofu, fish, chicken, Greek yoghurt | Satiety, steadier glucose, supports hormones |
| Non-starchy vegetables | Spinach, methi, bhindi, broccoli, lauki, salads | Folate, magnesium, fibre |
| Healthy fats | Nuts, seeds, olive or mustard oil, oily fish (such as salmon or sardines) | Omega-3s and insulin sensitivity |
| Fruit | Whole fruit with nuts or yoghurt, not juice | Antioxidants with fibre |
| Iron and B12 sources | Leafy greens, legumes, eggs, dairy, fish, or supplements if advised | Common gaps, especially in vegetarians |
Limit: sugary drinks, sweetened chai and coffee, refined flour (maida), packaged snacks, sweets and large portions of white rice.
Eating vegetables and protein before carbohydrates may also soften the post-meal glucose rise.
Practical takeaway: Pair every carbohydrate with protein and fibre, and keep portions consistent.
How can diet and lifestyle help you control diabetes and conceive?
- Eat at regular times. Long gaps followed by large meals cause bigger glucose swings.
- Walk 10-15 minutes after meals. Short post-meal walks reduce glucose spikes.
- Build muscle. Resistance training two to three times a week improves insulin sensitivity.
- Protect your sleep. Poor sleep worsens insulin resistance and cravings.
- Manage stress. Raised cortisol pushes glucose up and can disturb ovulation.
- Reach a healthier waist and weight gradually if advised. Even modest weight loss can improve ovulation in women with insulin resistance. Avoid crash diets, which can destabilise glucose and cycles.
- Avoid smoking and limit alcohol. Both affect fertility in men and women.
- Monitor. Home glucose readings or a CGM, as your doctor advises, show how your body responds to specific meals.
Practical takeaway: Consistency beats perfection. A repeatable daily rhythm does more than occasional strict dieting.
What should you consider when trying to conceive with diabetes?
Before you stop contraception, work through this checklist with your doctor and dietitian:
- Get a preconception review. Ask your doctor or endocrinologist to set your HbA1c target and plan the timing.
- Review your medications. Some drugs commonly used in diabetes and blood pressure care, such as certain ACE inhibitors, statins, and some newer diabetes medicines, may not be suitable in pregnancy. Never stop or change medication on your own.
- Start folic acid early. Usually at least 400 mcg daily, with a higher dose sometimes advised, ideally beginning at least a month before conception. Ask your doctor about your dose.
- Screen your eyes, kidneys and blood pressure. Pregnancy can accelerate retinopathy and kidney problems.
- Check thyroid function, especially with type 1 diabetes, where thyroid disease is more common.
- Include your partner. A semen analysis and a review of his metabolic health give a complete picture.
- Know when to seek help. If you are under 35 and have not conceived after 12 months, or over 35 and have not conceived after 6 months, or have irregular cycles, see a fertility specialist sooner.
- Watch for lows. Tighter control can increase hypoglycaemia risk, so your plan should be individualised.
Practical takeaway: Preparation is a team effort between you, your partner, your doctor and your dietitian.
Frequently asked questions
1. Can you get pregnant naturally if you have diabetes? Yes. Many women and couples with diabetes conceive naturally, especially when glucose is well managed before conception. Ovulation, partner factors, age and other conditions also play a role.
2. Does diabetes cause infertility? Diabetes does not automatically cause infertility, but poor control can reduce fertility in both sexes. It can affect ovulation, sperm quality and the likelihood of a healthy pregnancy.
3. What HbA1c is safe for conceiving? Guidelines generally aim for below 6.5% where this can be reached safely, but your doctor sets your target. Higher HbA1c around conception is associated with greater risk of miscarriage and congenital anomalies.
4. Can type 1 diabetics conceive naturally? Yes, and many do. Type 1 diabetes needs particularly careful planning for glucose, thyroid and eye health. Your endocrinologist and obstetrician should be involved before conception.
5. Does diabetes affect male fertility? It can. High blood sugar is associated with lower sperm motility and more DNA damage, and with erectile or ejaculatory problems. Improving glucose and metabolic health may support sperm parameters.
6. How long should I control blood sugar before trying? Around three months is a useful minimum, since HbA1c reflects about three months of glucose. Some people need longer, depending on where they start.
7. Will I need IVF if I have diabetes? Not necessarily. Many conceive naturally. If ovulation, sperm quality, age or other factors are involved, your fertility specialist may suggest IUI or IVF, and nutrition can support you through it.
8. Is the diabetes diet different when trying to conceive? The principles are similar, but intake of folate, iron, B12, protein and omega-3s deserves extra attention, and weight loss should be gradual, not aggressive.
