Characterized by watery or loose and frequent bowel movements, diarrhea is a common complaint in pregnant females. There are a number of factors that can result in diarrhea in first trimester of pregnancy, majority of which are minor ailments and not a cause for concern. However, diarrhea accompanied by vomiting or nausea will need prompt treatment to prevent dehydration. Diarrhea associated with pain and fever or presence of mucus or blood in stools can indicate something serious and requires a visit to a doctor.

Causes of Diarrhea in First Trimester of Pregnancy

Hormonal Changes

The first trimester of pregnancy is associated with production of large amounts of pregnancy hormones which can relax and slow down the gastrointestinal tract. This can be good for the fetus to absorb more nutrients that it needs to grow but bring an embarrassing result – diarrhea associated with bloating and constipation.

Changes in Diet

Pregnancy brings with itself a change in diet that includes eating more fiber-rich foods such as fruits, vegetables, along with extra water. While these dietary changes are great for both your health and your baby’s health, they may result in diarrhea, first trimester of pregnancy.

Intolerance to Lactose

Diarrhea during first trimester of pregnancy can also occur as a result of lactose intolerance which happens due to increased milk consumption by pregnant females. You can try eliminating milk from your diet for a few days to notice if there are any changes in the symptoms. However, make sure to take calcium from other sources during this period.

Taking Prenatal Vitamins

While iron present in the prenatal vitamins can result in constipation for some females, loose stools can result from other ingredients. Similar to milk intolerance mentioned above, stop taking vitamins for a few days to see if diarrhea goes away.

Certain Viruses

Pregnant females are more prone to get infected with stomach viruses; diarrhea is one of the common symptoms of such infections.

Sensitivities to Certain Foods

You may develop sensitivity to different foods during pregnancy. Food that has not caused any troubles before may now cause symptoms of bloating and diarrhea.

Ways to Prevent Diarrhea During First Trimester

The key to prevent diarrhea during first trimester of pregnancy is dietary modification. Avoid foods such as prunes, which are natural laxatives and spicy, fatty foods and dairy products. Spicy or fatty foods may be difficult to digest and may cause loose stools. Dairy products can result in diarrhea in lactose intolerant females. Such pregnant females should take other forms of calcium instead of dairy products.

Sugary drinks such as energy drinks or sodas should also be avoided by pregnant females as they may also disturb digestion. They can also cause excess weight gain during pregnancy. You should avoid drinking cokes, grape juice, and tea to prevent diarrhea during pregnancy. However, sports drinks can be a good choice as they are rich in electrolytes and they can help in rehydration. But make sure to choose the right sports drink after discussing with your physician as not all drinks have positive effects.
