What is Hyponatremia?

Hyponatremia is a condition characterized by an abnormally low concentration of sodium in the blood. Since sodium is an essential electrolyte in the body, not having enough of it can lead to various health problems such as excessive fluid intake, kidney dysfuntion, hormonal imbalances, and dehydration.

The symptoms of Hyponatremia vary depending on the rate at which sodium levels drop in the body.

Types of Hyponatremia

There are 3 types of Hypoatremia: Hypovolemia, Euvolemia and Hypervolemia each used to describe different state of body fluid volume in the vascular system.


Hypovolemia refers to a state of decreased blood volume in the circulatory system. It occurs when there is a loss in body fluid though bleeding, vomiting, severe diarrhea, excessive sweating or not enough fluid intake. Hypovolemia can lead to symptoms such as low blood pressure, rapid heartbeat, renal loss (ie. kidney failure)


Euvolemia refers to having normal/adequate blood volume in the circulatory system. This means that the amount of fluid in the body is balanced, and the circulatory system is functioning properly. Euvolemia is considered to be a healthy state in terms of fluid balance in the body.


Hypervolemia refers to having increased blood volume in the circulatory system. It occurs when there is an excess of fluid in the body due to excessive fluid intake, kidney disease or heart failure. Hypervolemia can lead to swelling, high blood pressure and even exacerbate congestive heart failure symptoms.

Maintaining the right fluid balance is essential for the body to function optimally. With Picmonic you can learn and master the topic of Hypoatremia and grasp the concepts easily with our Hypoatremia mnemonics and videos. Give it a try!
