If the blood pH falls below 7.35, the condition is defined as acidosis which may have serious consequences.
The causes of acidosis are quite severe and are not caused by food or diet.
Some of the most common causes of metabolic acidosis include: poisoning with carbon monoxide, cyanide, methanol, heart failure, in-born error of metabolism, poor lung function not allowing the exhaling of sufficient carbon dioxide, kidney failure, use of certain drugs (large doses of aspirin, alcohol, iron, acetazolamide), lactic acidosis (as a result of shock) and complications of poorly controlled diabetes type 1.
