Elevated Potassium Levels in Dogs

Dogs have to watch potassium levels, too.

Potassium is an electrolyte necessary for the proper functioning of the kidneys, nerves, muscles and digestive system, as well as regulating the rhythm of the heart. Hyperkalemia is the term used to describe an elevated level of potassium in the body. Humans and dogs alike can be affected by high potassium levels.

Hyperkalemia

Hyperkalemia can cause a variety of symptoms including vomiting, lethargy and muscle weakness, as well as severe complications to the heart. Hyperkalemia can occur in a variety of situations; however, the kidneys are usually involved.

Kidney Disease

Potassium is a waste product of normal metabolism that is flushed from the body by the kidneys. When the kidneys are not functioning correctly, potassium begins to accumulate in the bloodstream.

Addison's Disease

Addison's disease (hypoadrenocorticism) is a disease affecting the adrenal glands. The adrenal glands produce aldosterone, which regulates the amount of sodium and potassium in the body. Addison's disease causes hyperkalemia.

Ruptured Bladder

A ruptured bladder can occur due to trauma or an obstruction. Potassium, a normal waste product found in urine, begins leaking into the abdomen and is reabsorbed by the body; this leads to elevated levels in the bloodstream.

Warning

Hyperkalemia can cause heart arythmias in dogs as well as respiratory paralysis. If the potassium level is not controlled, both of these conditions can lead to death.
