Many patients find that sleep becomes more difficult during the third trimester. As the baby grows, physical changes can make it harder to get comfortable throughout the night.
Common reasons for disrupted sleep include heartburn, leg cramps, sinus congestion, and general discomfort as the abdomen increases in size. You may also wake more often at night to use the bathroom as the baby’s position places additional pressure on the bladder.
While these changes are common late in pregnancy, discussing ongoing discomfort at your prenatal visits can help identify ways to improve rest and overall comfort.
