Rhabdomyolysis (shortened as rhabdo) is a condition in which damaged skeletal muscle breaks down rapidly, often due to high intensity exercise over a short period. [6] [4] [5] Symptoms may include muscle pains, weakness, vomiting, and confusion.
Vomiting (the expulsion of gastric contents) is usually preceded by retching, but retching and vomiting can occur separately [6] and involve different sets of muscles. [7] During a retch, thoracic pressure is decreased and abdominal pressure is increased, which may serve to position gastric contents and overcome esophageal resistance. [6]
Early indications of abdominal trauma include nausea, vomiting, blood in the urine, and fever. [4] [6] The injury may present with abdominal pain, tenderness, [7] distension, or rigidity to the touch, and bowel sounds may be diminished or absent.

This is a potential cause of vomiting due to the inability of the proximal stomach smooth muscle to undergo receptive relaxation. The vagal afferents are activated during the gastric phase of digestion when the corpus and fundus of the stomach are distended secondary to the entry of a food bolus. The stimulation of the mechanical receptors ...
