Additional symptoms. Lactic acidosis caused by an enzyme deficiency can cause other bodily fluids such as cerebral spinal fluid and urine to have PH levels that are too acidic in addition to the blood. As lactic acidosis happens chronically or continuously over time, more symptoms can begin to manifest due to prolonged blood acidity. Untreated lactic acidosis can produce symptoms of delays in development and abnormalities of motor functioning. Excessive exhaustion, intense body weakness, pains and cramping in the abdominal area, reduced or no appetite, tachycardia, excessive muscle cramping all over the body, overall physical discomfort, episodic diarrhea, and chronic recurring headaches will usually result from prolonged untreated lactic acidosis.
