Are health problems ever caused by over alkalinity?

Metabolic alkalosis can be caused by prolonged vomiting, resulting in a loss of hydrochloric acid with the vomiting. Severe dehydration and the consumption of excessive alkali are other causes. It would be difficult to become over alkaline by diet alone, but this extreme is technically possible should a person eat only 100 % alkalizing foods and no proteins or other acid-forming foods.

If you urine pH is consistently 8 this most likely indicates a “false alkalinity.”
