Laxatives can cause stomach pain and cramps
Laxatives are used to treat occasional constipation. There are several types of laxatives, each with a slightly different way of promoting regular bowel movements. Stimulant laxatives do this by causing the muscles of the intestines to contract and move poop through the digestive tract. Although stimulant laxatives are the fastest-acting and often the most effective, they can cause stomach cramps and abdominal pain while working. This may make it difficult or uncomfortable to work out. Skipping the gym until you’re no longer constipated is one way to avoid stomach cramps while exercising. Another option is choosing a more gentle laxative that softens stool by absorbing water into the intestines. These laxatives may not work quite as fast as stimulant laxatives, but they are much less likely to cause cramps.
