How to Know if You Are Dehydrated When Pregnant

Dehydration is a potentially serious condition where your body loses too much water and it is not replaced sufficiently. Often, dehydration causes other sicknesses, especially heat-related illness like heat stroke or heat exhaustion. Dehydration is problematic for anyone, but it is even more dangerous for pregnant women. Dehydration in pregnant women can cause reduction of amniotic fluid, which can lead to birth deformities. Dehydration also causes muscle spasms and labor contractions, according to Epigee Women’s Health 1. Knowing the signs of dehydration can help you avoid these complications.

Notice if you are thirsty. This is the first sign of dehydration. According to the American Pregnancy Association, pregnant women should drink eight to 12 glasses of water per day 2. This amount should be increased in warm weather or if you have been vomiting or have diarrhea.
