Minerals and electrolytes are present in all the fluids of the body and it is essential that the right amount of minerals and electrolytes are present for the proper functioning of the body systems, muscles and so on. Minerals and electrolytes are obtained from the diet.
A change in the composition of these elements, especially electrolytes, can cause severe side effects. Certain medical conditions such as renal problems, diarrhea and vomiting, can alter the electrolyte levels. If the levels are altered significantly then they should be corrected with re-hydration to avoid the electrolyte imbalance from becoming extreme, as this can cause severe problems.
