If your usual shoes suddenly feel tight, or your fingers look a little puffy by evening, you are not alone. This swelling — medically called edema — affects most pregnant women to some degree, especially in the third trimester, and is usually completely normal even though it is uncomfortable.
Why Does This Swelling Happen?
During pregnancy, your blood volume increases by up to 50% to support your growing baby, and hormones cause your tissues to hold onto more fluid than usual. On top of that, your growing uterus presses on the large veins that carry blood back from your legs to your heart, so fluid pools in your feet and ankles — especially after long periods of standing or sitting, or in hot weather.
Tried-and-True Ways to Ease the Discomfort
You cannot prevent swelling entirely, but a few simple habits noticeably reduce how bad it feels throughout the day.
- Elevate your feet above heart level for ten to fifteen minutes, several times a day.
- Avoid standing or sitting continuously — move or change position roughly every hour.
- Wear supportive compression socks after checking with your doctor; they help circulation in your legs.
- Cut back on excess salt, and drink enough water even though that may sound counterintuitive.
- Sleep on your left side when possible — it reduces pressure on the major veins.
- Regular gentle walking improves circulation far better than sitting still for long stretches.
When Does It Need Urgent Medical Attention?
Mild, symmetrical swelling in both feet is normal, but watch for sudden, severe swelling in your face or around your eyes, swelling in just one leg accompanied by pain or redness, or a severe headache with blurred vision. These signs can be linked to high blood pressure, preeclampsia, or a blood clot, and call for contacting your doctor right away rather than waiting for your next appointment.
