How do antacids settle stomach?

Antacids work by neutralizing stomach acid through a chemical reaction, which helps alleviate symptoms of heartburn and indigestion. They typically contain alkaline substances like magnesium hydroxide, calcium carbonate, or aluminum hydroxide, which raise the pH level in the stomach. By reducing acidity, antacids provide quick relief from discomfort caused by excess stomach acid. Additionally, they can help protect the stomach lining and esophagus from irritation.
