The normal nature of stomach is acidic due to the presence of HCL. his acidic pH is necessary to facilitate the process of digestion. An antacid is usually consumed when the acidic level of the stomach exceeds beyond normal causing symptoms of the condition called acidity.
When we take antacids without any reason it will work like a buffer that alters the pH of a medium and reduce the normal acidic level in the stomach. Normal digestion cannot take place at this new pH. If we take any food after that indigestion will be the result.
So taking a hamburger after consuming antacid will cause indigestion or slow digestion.
