What would experts advise regarding Prenatal vitamins?

  1. Julie Lamppa, CNM RN, a nurse-midwife at the Mayo Clinic says, “Constipation in early pregnancy is common, so experiencing it regularly could offer a clue that you’re expecting. But for most of the women, it is probably not the first or most obvious sign of pregnancy. Constipation in pregnancy can begin early in the first trimester and can continue for days or weeks after the birth. But don’t worry, having early constipation in pregnancy doesn’t necessarily mean you’ll be plugged up for months on end. Often, women will find that it can wax and wane—or they get good control with a little change in their diet, activity, supplements or medications.” She further adds “The increase in progesterone levels plays a big part in causing constipation in the first trimester.” 

  2. Jessica Shepherd, MD, an ob-gyn and the founder of Sanctum Med + Wellness in Dallas, Texas, explains,” As progesterone increases during your pregnancy, it leads to slower-moving intestines.”This means slower digestion, which can lead to constipation.”

  3. The presence of iron in most prenatal vitamins (a mineral that has been linked to constipation) and not drinking enough water to meet your growing needs, can further elevate the problem, says Christine Greves, MD, a board-certified ob-gyn at the Winnie Palmer Hospital for Women & Babies in Orlando, Florida.
