Dumbass trainers.
That type of forced behavior, especially if repeated is textbook bulimia. Possible side effects?
Severe electrolyte imbalance Chronic dehydration, which is not uncommon with bulimia, can cause critical health issues. Low potassium levels in the blood can cause heart arrhythmia or cardiomyopathy. Calcium levels are reduced which weakens the bones. Low magnesium levels could result in dizziness, fatigue, seizures, muscle cramps, irregular heartbeat.
When your sodium level is off, cell can become dehydrated which could manifest itself in muscle cramps, headaches, seizures, intracranial hemorrhage and yes, death.
If the ESPN story is remotely accurate on this issue and if it was used with other linemen, like Jordan McNair, they are increasing the likelihood of these tragedies.
With the cause of death being listed as "heatstroke," most of the symptoms are the same as those caused by bulimia or binge eating.
