Compression Socks for Pregnancy: What to Know Before You Buy
This article is for general informational purposes only and isn't medical advice. Please talk to your doctor or midwife before using compression socks during pregnancy, especially if you have any underlying health conditions.
Swollen ankles and tired, heavy legs are a common experience during pregnancy, especially in the later trimesters. It's one of the reasons compression socks come up so often in pregnancy forums and from other parents — but it's worth understanding what they actually do before deciding if they're right for you.
Why Legs Can Swell During Pregnancy
During pregnancy, your body carries significantly more blood volume, and the growing uterus can put additional pressure on the veins that carry blood back up from your legs. Combined with hormonal changes that affect vein elasticity, this can lead to swelling, achiness, and sometimes varicose veins, particularly later in pregnancy.
What Compression Socks May Help With
Graduated compression socks are designed to support circulation in the lower legs by applying pressure that's strongest at the ankle and gradually eases toward the knee. Many people find this helps with the heavy, swollen feeling that can build up over the course of a day during pregnancy.
It's important to note that regular knee-high compression socks provide support for the lower leg only — they aren't a substitute for maternity support garments designed for the abdomen or lower back, and they don't treat underlying medical conditions.
Talk to Your Doctor First
Pregnancy affects everyone differently, and some conditions (like a history of blood clots, certain circulatory issues, or high-risk pregnancies) may need specific guidance on compression garments — including compression level and when during pregnancy to start or avoid wearing them. Your doctor or midwife is the right person to advise on what's appropriate for your specific situation.
What to Look For, If Your Doctor Approves
- A mild-to-moderate compression level (often 15-20mmHg for general pregnancy-related swelling, though your doctor may recommend a different level)
- A comfortable, non-restrictive fit that doesn't dig in behind the knee or at the top band
- Breathable material, since pregnancy can already come with increased body temperature
- Correct sizing based on your current calf measurement, which may change as pregnancy progresses
FAQ
Can I wear compression socks every trimester?
This depends on your individual health and your doctor's guidance. Some people wear them throughout pregnancy, while others are advised differently based on their circumstances — always check with your provider.
Do compression socks prevent varicose veins in pregnancy?
Compression socks are generally used to support comfort and circulation, not as a guaranteed way to prevent varicose veins. If you're noticing new or worsening varicose veins, that's worth discussing with your doctor.
What if my swelling is sudden or only in one leg?
Sudden, severe, or one-sided swelling during pregnancy can sometimes indicate a condition that needs prompt medical attention. Contact your doctor or midwife right away if you notice this.
A Note on Choosing a Pair
If your doctor gives the go-ahead, look for a comfortable, well-fitted pair. Compribe's compression socks offer graduated 15-20mmHg compression in a breathable material — but as always, check with your doctor first to make sure this compression level and use is right for you during pregnancy.
