Diseases of the adrenal gland (such as Addison's disease, that causes a decreased aldosterone secretion) lead to a decrease in kidney excretion of potassium resulting in hyperkalemia. Examples of medications that may lead to elevated potassium levels include: 1  nonsteroidal antiinflammatory drugs, 2  ACE inhibitors, 3  Angiotensin II receptor blockers (ARBs), and.  some types of diuretics.
Low levels of potassium can cause sodium sensitivity and an increase in blood pressure. Potassium also affects insulin levels. When potassium levels are low, there is a reduction in insulin secretion. A very low level of potassium causes a condition called hypokalemia.
