Potassium deficiency
A deficiency of potassium is called hypokalemia. Because potassium is so abundant in foods, potassium deficiencies are rare. However, a lack of potassium can occur during and after excessive fluid loss (because of perspiration, urination, the Diarrhea, vomiting excessive).

Signs and symptoms of potassium deficiency are:
* Muscle weakness, muscle pain,
* Fatigue,
* Confusion and irritability
* Digestive problems,
* Heart problems.
What are your chances of suffering a potassium deficiency?
Although potassium is easily absorbed and available in abundance, some people may suffer from a deficiency of potassium:
* Athletes: because they sweat a lot, athletes lose more potassium than anyone else. Athletes should work with a nutritionist or a doctor specializing in sports to monitor their electrolyte levels and consider taking supplements of potassium,
* People suffering from digestive diseases: Any person suffering from celiac disease, Crohn’s disease or syndrome irritable bowel have more difficulty to absorb potassium,
* The drinking of alcohol: the more you drink alcoholic beverages, you need to urinate more and more so your body lose potassium,
* Persons under medical treatment, on diuretics or laxatives as: because some medications cause Diarrhea or loss of fluid, any person taking the drug daily doses should consult their doctor to ensure that their levels of potassium remain normal.
A cardiac arrest can occur especially if the changes in serum potassium have been abrupt.
