Antacid
Reporting from Healthline, magnesium hydroxide (Mg(OH)2) can neutralize stomach acid, so it can be used as a stomach medicine.
Magnesium hydroxide has alkaline properties which can neutralize acid produced by the stomach with the following reaction:
Mg(OH)2 + 2HCl → MgCl2 + 2H2O
Meanwhile, magnesium hydroxide dissolves in dilute acid, helping it neutralize stomach acid more easily.

Purgative
Apart from being used as a stomach medicine, magnesium hydroxide (Mg(OH)2) is also used as a laxative.
Hydroxide ions produced by magnesium hydroxide to neutralize the stomach move to the intestines (if Mg(OH)2 is used in larger doses).
Reporting from PubChem, hydroxide ions in the intestine attract and retain water, thereby increasing bowel movements or peristalsis.
This can help a person to defecate.
