High calcium in blood
High calcium in blood or hypercalcemia is a serious health complication of drinking alkaline water on a regular basis. It can cause nausea, vomiting, abdominal pain, confusion, and muscle weakness. If left untreated, hypercalcemia can lead to kidney stones, kidney failure, and even death.
Treatment for high calcium in blood depends on the underlying cause. In most cases, it involves stopping drinking alkaline water and making lifestyle changes (such as increasing fluid intake and avoiding caffeine and salt).
