Milk-alkali syndrome is a medical condition that can occur when there is an imbalance of acid and alkali in the body. It is also known as alkalosis and hypercalcemia. Some of the synonyms for this condition include calcium-alkali syndrome, milk-alkali syndrome poisoning, milk-alkali acidosis, and milk-alkali toxicity. The condition is usually caused by excessive intake of calcium and alkali compounds such as antacids. The symptoms of milk-alkali syndrome include nausea, vomiting, confusion, and muscle weakness. If left untreated, it can lead to potentially life-threatening complications such as kidney failure and cardiac arrest. Early diagnosis and treatment are essential to manage the condition effectively.
