But how much water should you drink and how do you know you aren’t dehydrated? What can happen if you don’t drink enough water? Let’s find out everything about hydration and pregnancy health.

Your body requires ample water to promote blood circulation in your baby. If you don’t drink responsibly, you will be at a higher risk of pregnancy complications like low amniotic fluid. Amniotic fluid is the liquid that surrounds the baby. The water that you drink is also a source of fluoride and this mineral is crucial to the development of the baby’s teeth and bones.

Another recurring problem during pregnancy is constipation that happens because of hormonal changes in the body. If you take iron supplements, your constipation issues will worsen and the simplest solution to this problem is having enough fluids.
