Why is potassium an important electrolyte
Answer
Potassium (K+) is the most common electrolyte in the intracellular fluid (ICF) compartment of the body. Only a small amount is found in the bloodstream. 3.5 to 5 milliequivalent per liter (mEq/L) is the normal laboratory value, therefore, any changes to this value can cause major disruptions in the body.
What happens if your potassium is low?
Hypokalemia (low potassium) occurs when an individual serum potassium is below 3.5 mEq/L. Most cases of hypokalemia result from inadequate intake of K+ or excessive loss of K+. Some foods rich in potassium are bananas, avocados, and potatoes. Hypokalemia most often occur as a result of medication such as K+ wasting diuretics including lasix and hydrochlorothiazide. These drugs increase urination.
Hypokalemia causes:
- Constipation
- Excessive Thirst
- Tingling and Numbness in Hands and/or Feet'
- Weakness and Fatigue
