Excess of Antacids

Antacids contain mild bases like sodium bicarbonate (NaHCO₃) and milk of magnesia (Mg(OH)₂).

Excessive use of a base like sodium bicarbonate causes severe problems.

Sodium bicarbonate contains a large amount of sodium. If you are on sodium restricted diet or have high blood pressure talk to your health care professional before taking sodium bicarbonate.

Excessive use of milk of magnesia causes diarrhea. Symptoms of

high magnesium levels, symptoms of dehydration, stomach/abdominal pain, bloody stools, rectal bleeding.

Skin Contact

Chemical burns happen when exposed tissue comes into contact with a base. In most cases chemical burns are minor and only cause some skin irritation. Chemical burns must immediately be neutralized, then go to the doctor. A base can be neutralized with an acid and vice versa.

Ingestion

Ingestion of a base can cause the human body to change its pH level; if the body is not at normal pH level, the organs will not function properly which can result in organ failure and even death. Ingestion also causes immediate burns that are similar to skin contact in the mouth, throat, and stomach.

Inhaling

Strong solutions of acids and bases can cause respiratory distress and even organ failure. This can be exacerbated in those who have asthma.

Tissue Damage

Deep tissue damage can occur in addition to a chemical burn. It is important to get to the doctor after a chemical burn so they can tell you if there is such damage. Avoiding the doctor can result in extreme pain in infected muscle and muscle death.

Eye Damage

A base such as pure ammonia can cause eye damage. This includes burning of the exposed tissue, and can cause burning of interior tissue that can result in permit blindness.
