Definition of Milk-alkali syndrome:

Milk-alkali syndrome is an acquired condition in which there are high levels of calcium (hypercalcemia) and a shift in the body's acid/base balance towards alkaline (metabolic alkalosis).

Causes, incidence, and risk factors:

Milk-alkali syndrome is caused by excessive consumption of milk (which is high in calcium) and certain antacids, especially calcium carbonate or sodium bicarbonate (baking soda), over a long period of time.

Calcium deposits in the kidneys and other tissues can occur in milk-alkali syndrome. Consumption of vitamin D, which is often added to milk bought at the supermarket, can worsen this condition.

In the past, milk-alkali syndrome was often a side effect of treating peptic ulcer disease. It is rarely seen today, because newer, better medications are available for treating ulcers.
