DON'T LET THIS HAPPEN TO YOU

This guy was all OK after replacing lost electrolytes and fluid
Prevention is easy and best as treatment can be difficult. 

During exercise, sweat output often exceeds water intake, producing a body water deficit (hypohydration). Exercise performance can be compromised by a body water deficit, particularly when exercise is performed in hot climates. It is recommended that individuals begin exercise when adequately hydrated. This can be facilitated by  drinking 400 mL to 600 mL of fluid 2 hours before beginning exercise and drinking sufficient fluid during exercise to prevent dehydration from exceeding 2% body weight. A practical recommendation is to drink small amounts of fluid (150-300 mL) every 15 to 20 minutes of exercise (Latzka WA, et al. Water and electrolyte requirements for exercise. Clin Sports Med. 1999 Jul;18(3):513-24) For athletes performing high-intensity exercise in the heat, sweating rates of 1.0–2.5 L/h are common and this needs to be replaced.

   
Our electrolyte concentration in the body is controlled by a variety of hormones; these are mostly found in the kidney and the adrenal glands. And these specialized kidney cells monitor the amount of sodium, potassium, and water in the bloodstream The main electrolytes exist in the form of calcium, chlorine, magnesium, phosphate, potassium, and sodium that can be obtained from fluids, supplements, and foods. Sodium, Potassium and Magnesium are vital, and combined with glucose and water is an essential supplement (drink) to any serious athlete who is pushing themselves to the point of exhaustion.

   
 When exercising at extreme levels over time these electrolytes are lost in sweat and exhaled breathing. Sodium chloride is the primary electrolyte in sweat, with potassium, calcium, and magnesium present in smaller amounts. If not replaced an imbalance can cause muscle spasms, kidney failure and cardiac arrhythmias that can lead to coma and death.

Prevention is the answer. always replace loss water and electrolytes.
