Few mechanisms: 1. Low intake in food 2. Loss in secretions- urine, gastrointestinal-vomitus and stool, sweat 3.Increased traslocation of k in to the cells in certain conditions eg. Insulin excess, mineralocorticoid( aldosterone - a hormone secreted by adrenal gld.) excess are associated with low potassium.There is a genetically acquired condition called periodic hypokalemic syndrome characterized by low k level.

The most common cause is Primary Aldosteronism. Most will also have high blood pressure. K can be low for years before Dx is recognized. Other Sx are nocturia, muscle cramps and difficult to control BP.

A 41-year-old member asked:

How do potassium levels affect cardiac output?

Dr. Irv Lohanswered
Cardiology 49 years experience
Not directly: Cardiac output is the amount of blood flow generated by the heart over a given time frame. Potassium is a critical electrolyte for body health and cardiac function, especially its rhythm. Although high or low potassium levels can create major, potentially fatal, irregularities in the heart rhythm, those levels do not directly affect the cardiac output per se.

Emergency Medicine 10 years experience
Dilation of vessels: Nitroglycerin is only used in emergency situations, it works by causing dilation of blood vessels, which will then help to lower blood pressure. This also may cause a patient to get a headache as Nitroglycerin causes widespread dilation of blood vessels including blood vessels in the brain.
