We're not talking about electrolytes by the cupful.
More dangerous than narcotics? Show me a link...
Yes, one poster advised potassium tablets. I absolutely agree that Pedialyte, coconut water, oral rehydration salts, and Gatorade are necessary and beneficial, but must be accompanied by consumption of clean fresh water. Hydration is the key. The reason that sodium and glucose are added to water (pedialyte, rehydration salts) is not necessary to increase those levels, but because of how your body absorbs nutrients in the small intestine.
HYPERkalemia (high potassium) can be caused by dehydration secondary to fever and poor oral intake. In normal healthy adults, your body does a very good job of regulating sodium, potassium, and the other electrolytes. This may not be the case in ill and dehydrated elderly or children. Giving an elderly, dehydrated person potassium tablets can quickly kill them. Potassium is essential to muscle, heart, and nerve function. These electrolytes also have a narrow therapeutic index (lows and highs). Your cells run by exchanging sodium and potassium. An increase in serum potassium levels causes increased excitability of the [heart] cells and left unchecked [by your kidneys in a hydrated healthy adult] will cause a deadly dysrhythmia.
HYPERnatremia, can be caused by dehydration,
watery diarrhea, or dehydration with salt intake and no rehydration [the point] is a higher than normal serum sodium level. Water is attracted to sodium, high levels of sodium in the blood will cause fluid to shift out of your [brain] cells and result in shrinkage of cells causing confusion, seizure, coma, and death. One of the differentials is Cholera, Cholera causes watery diarrhea.
HYPOnatremia, which can be caused by diarrhea [not watery] is low serum sodium. Basically too much water. This causes the opposite problem. Because the cells have more sodium than the blood, the water enters the cells and causes brain swelling which causes confusion followed by seizure, coma, and death.
The reason I suggest that this can be more dangerous than narcotics is because people do not think that electrolytes are dangerous. And, the mentality when it comes to medicine in the DR is "If some is good, more must be better right?" Also, a narcotic overdose is easily recognizable and treatable. The signs of a narcotic overdose are low blood pressure and pulse, constricted pupils, and shallow breathing. It is also very simple to treat. An electrolyte imbalance on the other hand is not. The symptoms are not easily or quickly recognizable. Lab tests and someone with a high level of competency in reading the results is required. The treatment requires intensive care and continuous monitoring. You cannot just give someone with low sodium a buncof salt, you will kill them.
If you are a normal healthy person who is not malnourished and well hydrated, taking a potassium pill is a waste of money. You will have expensive urine. If you are ill and have decreased urine function secondary to dehydration and poor oral intake, taking potassium tablets or sodium will kill you.
Drink water, drink water and Gatorade, drink water and Pedyalite, drink water and coconut milk.
