What is a bowel movement?
Digestion begins in your mouth and ends in your bowels. A bowel movement (pooping) is the last stop in your digestive tract. Normal bowel movements occur anywhere from three times a day and three times a week, and involve poop that is brown, soft to firm in texture, and easy to pass. Sometimes, however, bowel movements are not normal.
The two most common types of abnormal bowel movements are constipation and diarrhea. Constipation occurs when poop passes through the large intestine too slowly. Diarrhea occurs when poop passes through the large intestine too quickly. If you experience either frequently, you may have a digestive problem.
Do protein shakes affect bowel movements?
In the short term, protein shakes are known to cause uncomfortable gastrointestinal (GI) side effects, including constipation and diarrhea. In the long term, many protein shakes can change the composition of your gut microbiome, which can also affect your bowel movements. If you frequently experience constipation or diarrhea after drinking protein shakes, you have come to the right place. The rest of this article is dedicated to helping you understand why some protein shakes can disrupt your bowel movements.
