Lactic acid is the last biochemical metabolite in the metabolism of anaerobic respiration (energy production without oxygen). The body makes lactic acid to synthesize limited ATP (energy compound of the body), by burning glucose. This is when there is inadequate or no oxygen to convert glucose to energy. This mostly happens in the working muscles(muscular fatique). This is also the first step of ATP synthesis (anaerobic phase) in the body. The process of obtaining more energy bu using oxygen is the second phase (Kreb’s Cycle), continues with pyruvate . Lactic acid remaining at this step, either accumulates (lactic acidosis) or is eliminated by the kidneys. It is mainly produced in muscle and red blood cells.
Interpretation: If lactic acid accumulates too much in the body, abdominal or stomach discomfort, decreased apetite, diarrhea, fast, shallow breathing may occur due to acidic imbalance caused by the molecule. This should be promptly brought into balance by the clinician.
