Which substance is commonly used as an antacid and laxative?

Milk of magnesia is a commonly used substance that serves both as an antacid and a laxative. As an antacid, it helps neutralize stomach acid, providing relief from conditions like heartburn and indigestion. Its active ingredient, magnesium hydroxide, works effectively to raise the pH level in the stomach, which in turn minimizes acidity.

In addition to its antacid properties, milk of magnesia is also well-known for its laxative effects. It acts by drawing water into the intestines, which helps to soften stools and stimulate bowel movements, making it an effective option for individuals dealing with constipation.

While other options may have specific uses in the realm of gastrointestinal health, they do not provide the dual benefits of both antacid and laxative actions as milk of magnesia does. This versatility is what makes it a popular choice among patients seeking relief from both acidity and constipation simultaneously.
