Laxative overdose Health Article

Definition

A laxative is a medication used to produce bowel movements. Laxative overdose occurs when someone accidentally or intentionally takes more than the normal or recommended amount of this medication.

Most laxative overdoses in children are accidental. However, some people abuse laxatives by regularly taking overdoses in an effort to lose weight.
