What is constipation?
Constipation involves when one struggles to poop, or with bowel movements. This commonly occurs when the food your body no longer needs hardens in the lower part of your digestive tract, instead of moving out as stool.
Constipation is also much more common during pregnancy due to hormonal changes. Whereby 16% – 39% of women suffer from constipation, making it difficult or painful to pass stools, especially in the third trimester when the fetus is heaviest and putting the most pressure on your bowels.
However, this issue often resolves itself as pregnancy passes.
What is constipation during pregnancy caused by?
Constipation can be caused by a myriad of reasons, one being low levels of dietary fibre, lack of exercise or lack of water.
Alternatively, hormonal changes can cause the gut to work less efficiently and food to move more slowly through the intestines, causing reduced gastric mobility.
The more the food remains in the intestines, the more moisture is absorbed and the waste is hence harder to pass. Lastly, fetus’ extra weight can put extra pressure on your bowels.
Symptoms of constipation during pregnancy
Some symptoms of constipation are being able to poop only a few times a week, straining to poop, having a bloated and gassy belly, as well as lumpy and hard stools.
