Lactic acidosis is commonly found in people who are unwell, such as those with severe heart and/or lung disease, a severe infection with sepsis, the systemic inflammatory response syndrome due to another cause, severe physical trauma, or severe depletion of body fluids. [3]
It was once believed that lactic acid build-up was the cause of muscle fatigue. [14] The assumption was lactic acid had a "pickling" effect on muscles, inhibiting their ability to contract. The impact of lactic acid on performance is now uncertain, it may assist or hinder muscle fatigue. [citation needed]
Affected infants have severe lactic acidosis, a build-up of ammonia in the blood (hyperammonemia), and liver failure. They experience neurological problems including weak muscle tone , abnormal movements, seizures, and coma. Infants with this form of the condition usually survive for less than 3 months after birth.

If the load on muscles is greater than the body's ability to recycle lactate back into glucose, lactate will start to build up in the blood. Once lactate reaches its renal re-absorption threshold (5–6 mmol/L in general population), it gets lost to urine, wasting many calories (and producing bright matte yellow particles on surfaces where ...
It was once believed that lactic acid build-up was the cause of muscle fatigue. [8] The assumption was lactic acid had a "pickling" effect on muscles, inhibiting their ability to contract. Though the impact of lactic acid on performance is now uncertain, it may assist or hinder muscle fatigue.
Damage to the sarcolemma and sarcoplasmic reticulum from direct trauma or high force production causes a high influx of calcium ions into the muscle fibers increasing calcium permeability. Calcium ions build up in the mitochondria, impairing cellular respiration. [7] The mitochondria are unable to produce enough ATP to power the cell properly.
Mitochondrial myopathy literally means mitochondrial muscle disease, muscle disease caused by mitochondrial dysfunction. The mitochondrion is the primary producer of energy in nearly all cells throughout the body. The exception is mature erythrocytes (red blood cells), so that they do not use up the oxygen that they carry.
Congenital lactic acidosis is a rare disease caused by mutations in mitochondrial DNA (mtDNA) that affect the ability of cells to use energy and cause too much lactic acid to build up in the body, a condition called lactic acidosis.
