Learn About Milk-Alkali Syndrome
Milk-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.

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 many antacids (such as Tums).
A high level of vitamin D in the body, such as from taking supplements, can worsen milk-alkali syndrome.
Calcium deposits in the kidneys and in other tissues can occur in milk-alkali syndrome.
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)
- Nausea or vomiting
- Other symptoms that can result from kidney failure
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.

This condition is often reversible if kidney function remains normal. Severe prolonged cases may lead to permanent kidney failure requiring dialysis.
The most common complications include:
- Calcium deposits in tissues (calcinosis)
- Kidney failure
- Kidney stones
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.
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.
Summary: Jansen s Metaphyseal Chondrodysplasia (JMC) is a very rare disorder with only approximately 30 people known to have the disease worldwide. It is caused by parathyroid hormone 1 receptor (PTH1R) variants leading to constitutive activation of the receptor for parathyroid hormone (PTH) and parathyroid hormone-related peptide (PTHrP). PTH1R is predominantly expressed in the kidneys and bone and growth...
Summary: Intracerebral hemorrhage (ICH) is the most deadly and debilitating form of stroke. To date, effective treatment that could improve the functional outcome of ICH remained elusive. In a mice model of ICH, it was demonstrated that high dose Vitamin D (VitD) treatment enhanced hematoma resolution by promoting reparative macrophage differentiation and improved neurobehavioral performance in mice. Hence...
