second most common cause of acid-base imbalance. recognized by low blood pH and HCO3- levels. indicated by rising blood pH and HCO3- levels, is much less common than metabolic acidosis. typical causes are vomiting of the acidic contents of the stomach and intake of excess base.
When bicarbonate levels are higher or lower than normal, it suggests that the body is having trouble maintaining its acid-base balance or that somone has upset their electrolyte balance, perhaps by losing or retaining fluid. Both of these imbalances may be due to a wide range of dysfunctions. Some of the causes of a low bicarbonate level include: 1  Addisonâs disease. 2  Chronic diarrhea. 3  Diabetic ketoacidosis. 4  Metabolic acidosis. 5  Kidney disease. 6  Ethylene glycol or methanol poisoning. 7  Salicylate (aspirin) overdose.
