How long can a person go without defecating?

The length of time a person can go without defecating varies widely, but generally, most healthy individuals will have a bowel movement anywhere from once a day to once every few days. Some people may not defecate for up to a week without experiencing significant discomfort, while others may begin to experience constipation after just a few days. Prolonged absence of bowel movements can lead to complications and discomfort, so it's important to seek medical advice if someone goes more than a few days without defecating.
