Milk-alkali syndrome
Calcium-alkali syndrome; Cope syndrome; Burnett syndrome; Hypercalcemia; Calcium metabolism disorderMilk-alkali syndrome is a condition in which there is a high level of calcium in the body (hypercalcemia). This causes a shift in the body's acid/base balance toward alkaline (metabolic alkalosis). As a result, there can be a loss of kidney function.
Hypercalcemia
Hypercalcemia means you have too much calcium in your blood.

Read Article Now Book Mark ArticleCauses
Milk-alkali syndrome is almost always caused by taking too many calcium supplements, usually in the form of calcium carbonate. Calcium carbonate is a common calcium supplement. It is often taken to prevent or treat bone loss (osteoporosis). Calcium carbonate is also an ingredient found in antacids (such as Tums).
Osteoporosis
Osteoporosis is a disease in which bones become fragile and more likely to break (fracture).

Calcium deposits in the kidneys and in other tissues can occur in milk-alkali syndrome.
Symptoms
In the beginning, the condition usually has no symptoms (asymptomatic). When symptoms do occur, they can include:
- Back, middle of the body, and low back pain in the kidney area (related to kidney stones)
- Confusion, strange behavior
- Constipation
- Depression
- Excessive urination
- Fatigue
- Irregular heartbeat (arrhythmia)

Treatment
In severe cases, treatment involves giving fluids through the vein (by IV). Otherwise, treatment involves drinking fluids along with reducing or stopping calcium supplements and antacids that contain calcium. Vitamin D supplements also need to be reduced or stopped.
Outlook (Prognosis)
This condition is often reversible if kidney function remains normal. Severe prolonged cases may lead to permanent kidney failure requiring dialysis.

When to Contact a Medical Professional
Contact your health care provider if:
- You take a lot of calcium supplements or you often use antacids that contain calcium, such as Tums. You may need to be checked for milk-alkali syndrome.
- You have any symptoms that might suggest kidney problems.
Prevention
If you use calcium-containing antacids often, tell your provider about digestive problems. If you are trying to prevent osteoporosis, do not take more than 1.2 grams (1200 milligrams) of calcium per day unless instructed by your provider.
