All at once, your digestive system goes on the fritz. Your trio of symptoms -- heartburn, flatulence and constipation -- is putting a damper on your otherwise sunny disposition. And just as you were able to enjoy all the foods that made you queasy just a few short weeks ago. Doesn't seem fair, does it?
Your body's hormonal changes are slowing your digestive process and causing the protective valve between your stomach and esophagus to relax. This means food is passing through your intestines at a slower rate. Plus, the iron in your prenatal vitamin makes constipation even worse. Help your digestive system get back on track by eating high-fiber foods and fresh fruits and vegetables every day. Top off your meals with at least 64 ounces of water (and a glass of prune juice, too). Ask your doctor if you can take a fiber supplement. If straining is still a problem, your doctor may recommend an over-the-counter stool softener. In most cases, these are OK for pregnant women.
Your gastrointestinal woes could keep you from gaining weight during the first trimester, but don't worry: Your baby's still getting the nutrients she needs from your body's stores.
