Can you exercise with gestational diabetes?
Yes, and it's part of the treatment: being active lowers your blood sugar, and NICE advises regular exercise such as walking after meals. The usual pregnancy rules apply, so tell your midwife or doctor before starting something new, and ask first if you have a complication such as bleeding, pre-eclampsia or a low-lying placenta. Gestational diabetes on its own isn't a reason to avoid exercise.
What is the best exercise for gestational diabetes?
Walking after meals is the simplest and best tested, and swimming, a static bike, pregnancy yoga and strength training with light weights or a band all count. Most of the programmes that helped in trials mixed aerobic exercise with some strength work. Choose what you can keep doing most days.
How long should I walk after eating with gestational diabetes, and how soon?
NICE and RCOG suggest 30 minutes, Diabetes UK 15 to 20 minutes within 30 minutes of a meal, and ACOG 10 to 15 minutes after each meal, so any of these counts. Our suggestion is to start within about 30 minutes of finishing and walk for 10 to 30 minutes at a pace where you can still talk. If you can only manage one walk a day, make it after your biggest meal.
How much exercise should I do with gestational diabetes?
Aim for at least 150 minutes of moderate activity a week, such as 30 minutes on 5 days, plus strength exercises on 2 or more days. Moderate means you can talk but not sing. If you weren't active before, start with about 10 to 15 minutes a day and build up.
Does walking help with gestational diabetes?
Yes. Across 11 trials, exercise lowered both fasting and after-meal blood sugar compared with usual care, and in a small trial, 20 minutes of walking after each main meal lowered blood sugar through the day. There isn't enough evidence yet on whether it changes the baby's birth weight.
Can I do strength training or squats with gestational diabetes?
Yes. The NHS suggests strength exercises twice a week, and in one trial, band exercises 3 times a week meant fewer women needed insulin, though other trials haven't shown that. Use light weights or a band, breathe out on the effort, and after the first trimester avoid moves flat on your back.
Can exercise cause a hypo with gestational diabetes?
Hypos are a risk if you take insulin or glibenclamide, not with diet changes alone, and they're uncommon with metformin on its own. On insulin, check before and after exercise, treat a reading below 4 mmol/L first, carry glucose tablets or a sugary drink, and agree a plan with your diabetes team. Never change a dose yourself.
My fasting numbers are high. Will exercise before bed help?
No trial has tested exercise at bedtime; an after-dinner walk is the habit that's been tested, and exercise lowered fasting levels a little in trials. High fasting readings often need medicine, so tell your team, who may also suggest a bedtime snack. If you're on insulin, our suggestion is not to add late-evening exercise without a plan from them.
Should I exercise before my glucose tolerance test?
Follow the instructions in your appointment letter: the test is done after fasting, and you rest between the blood tests. Don't try to change the result, because if gestational diabetes is missed, you miss the care that lowers the risks for you and your baby.
What if walking hurts, for example with pelvic girdle pain?
Our suggestion: try a static or recumbent bike, swimming, or the standing moves in the 10-minute after-meal routine, leaving out the side-steps. If standing is hard, march and do calf raises sitting down after a meal; Diabetes UK says try not to sit still after eating. Ask your midwife about a physiotherapy referral.
When should I stop exercising and get help?
Stop and call your midwife or maternity unit for bleeding, fluid leaking, regular painful contractions, chest pain, dizziness, a headache, muscle weakness, or calf pain or swelling. Get help straight away for any change in your baby's movements, and never go to sleep ignoring it. Call 999 if you think it's a life-threatening emergency.
Does gestational diabetes go away after birth?
Usually, but your risk of type 2 diabetes is about 10 times higher, so have a blood test 6 to 13 weeks after the birth and every year after that. Staying active, keeping to a healthy weight and breastfeeding all help, and in England you can sign yourself up to the NHS Diabetes Prevention Programme.
