What causes diarrhea in early pregnancy before a missed period?

Most women develop cravings during ovulation or right after conception. These sudden changes in the diet can lead to diarrhea early in pregnancy.

Sometimes increased intake of fruits and vegetables may cause unintentional diarrhea, which in many cases stops within a short period. Some pregnant women also become sensitive to some foods especially lactose (dairy products such as milk and cheese). Other than being one of the first signs of pregnancy, these could also be the cause of diarrhea after implantation.

3. Lactose intolerance

Studies show that a majority of women increase their intake of milk in pregnancy, and even before a missed period.

Dr. Spock explains that “having a few milk- free days may help alleviate symptoms if indeed it is lactose intolerance.

4. Prenatal vitamins

Iron which is the leading prenatal supplement taken early in pregnancy might be the cause of the diarrhea sign in early pregnancy. It is advisable to skip some days without taking your multivitamin and monitor the effect to determine if they are the cause of diarrhea.

Some ingredients in iron have been found to either cause diarrhea or constipation after prolonged use during pregnancy.

  • Excessive water intake causes imbalance in the internal environment which causes the body to naturally expel some to maintain balance.
