As pregnancy progresses, the extra weight at the front shifts your centre of gravity, the ligaments around the pelvis soften, and the lower back and hips work harder with every step. For many women this shows up as an ache in the lower back, pain across the front or sides of the pelvis, or simply a heavy, dragging feeling by the end of the day. A pregnancy support belt is a simple way to take some of that strain.
Types of maternity support
Under-bump support belts
A firm band that sits below the bump and across the lower back, usually with adjustable straps. It gently lifts the weight of the bump and supports the lower back and pelvis. This is the most common type for back and pelvic girdle pain from the second trimester onwards.
Belly bands
A wide, soft, stretchy band that covers the bump. Belly bands give light all-over support, help clothes fit comfortably and are popular for everyday wear and exercise. They provide less lift than an under-bump belt.
Full support cradles
These combine an under-bump belt with an upper strap over the bump or shoulders, giving more lift for larger bumps or twin pregnancies. They are bulkier but can be worth it later in pregnancy.
Pelvic or SI belts
A narrower belt worn low around the pelvis to compress and stabilise the sacroiliac joints. Often recommended by physiotherapists for pelvic girdle pain. See our separate guide to sacroiliac belts.
How to wear a pregnancy support belt
- Put it on while standing, with the main band sitting under the bump and across the lower back.
- Fasten it so it feels supportive without squeezing the bump. You should breathe easily and feel no pressure on the abdomen.
- Adjust the side or shoulder straps to fine-tune the lift.
- Wear it for the activities that bother you most, such as walking, standing, housework or work, and take it off when resting.
Comfort tips
- Wear it over a vest or thin top if the edges rub.
- Check the fit every few weeks as your shape changes; most belts are adjustable for this reason.
- Limit wear to a few hours at a time and keep moving. The belt supports you; it does not replace the muscles that need to stay active.
- Choose breathable fabrics for warmer months.
After the birth
Some women continue to use a support band in the weeks after birth for comfort and gentle abdominal support, particularly after a caesarean. Follow the advice of your midwife or GP, and do not use a tight binder without guidance.
When to speak to your midwife or GP
Always tell your midwife about back or pelvic pain. Seek advice promptly if pain is severe, spreads down the legs, is accompanied by numbness or weakness, or if you have any abdominal pain, bleeding or reduced movements from the baby. A women's health physiotherapist can assess pelvic girdle pain and recommend the right support and exercises.
Frequently asked questions
When can I start wearing a support belt?
Most women begin from around 20 weeks when the bump starts to affect posture, but there is no fixed rule. Use one when you feel it helps.
Is it safe for the baby?
A correctly fitted under-bump belt supports the weight of the bump from below rather than compressing it. Check with your midwife if you are unsure.
Can I exercise in it?
Many women wear a belly band or light support belt for walking, swimming or pregnancy exercise classes. Choose a flexible design and avoid anything that restricts breathing.
