The pathophysiology of myogenic muscle cramps, in contrast, is usually the result of disrupted energy production in muscle cells and occurs most commonly in metabolic myopathies associated with disorders of glycogen, lipid, or mitochondrial metabolism. 14 Metabolic myopathies cause deficient ATP levels. 14 Because muscle relaxation is an adenosine triphosphate (ATP)-dependent active process ...
- Edema. Edema, which is characterized by swollen and puffy skin, is a classic symptom of kwashiorkor. Scientists believe it is caused by low amounts of human serum albumin, which is the most abundant protein in the liquid part of blood, or blood plasma (5).
- Fatty Liver. Another common symptom of kwashiorkor is a fatty liver, or fat accumulation in liver cells (6). Left untreated, the condition may develop into fatty liver disease, causing inflammation, liver scarring and potentially liver failure.

A muscle spasm is different than a muscle twitch. A muscle twitch, or fasciculation, is an uncontrolled fine movement of a small segment of a larger muscle that can be seen under the skin.
Nov 11, 2017 · Muscle cramps are primarily caused by a lack of ATP in the body. ATP forces the myosin to release the actin; thus, the muscle relaxes and the cramp is relieved. Another cause could be the lack of magnesium, which helps the ATPase sodium/potassium pump, which, in turn, returns the voltage to resting potential and relaxes the muscle. Share.
