Common Physical Changes During Pregnancy

Aches and pains. During pregnancy, ligaments and tendons throughout your body stretch, both to accommodate the growing baby and to allow the baby out during labor. This can lead to achiness and even pain, particularly in the lower abdomen. You may also experience carpal tunnel syndrome in one or both hands, caused by compression of the nerves that carry signals to the hand and fingers. Acetaminophen or ibuprofen can help, as can exercise. Ibuprofen is generally not recommended after 28 weeks.

Shortness of breath. By the end of your pregnancy, with the baby pressing up against your diaphragm, you may feel as if you can't get enough air. This is called dyspnea, or shortness of breath. It's also a sign to slow down. If you feel uncomfortable, find a position (lying on your side?) that allows you to breathe more deeply.

Constipation. Thank those pregnancy hormones again for this symptom. Try to avoid straining, as that can lead to hemorrhoids. Instead, follow basic advice for constipation: Get regular exercise, drink plenty of water and up the fiber in your diet. If you still feel constipated, try a stool softener like Colace, an over the counter medication that can help relieve hemorrhoids.

Heartburn and gas. Blame the crowded space in there for this symptom, which most pregnant women experience in the third trimester. The pressure of the uterus on the stomach, coupled with the relaxation of the valve between the stomach and esophagus, allows stomach acid to "reflux" into your throat. Over-the-counter heartburn options like Tums, Mylanta and Mylanta Gas are considered safe during pregnancy.
