Hyponatremia and hypothyroidism: Is there a link?
While more research is still necessary, evidence suggests a possible link between severe hypothyroidism and hyponatremia. This may be due to how thyroid hormones can affect kidney function.
Hyponatremia is a condition that describes low levels of sodium in the blood. Hypothyroidism refers to a condition where the thyroid gland is unable to produce enough thyroid hormone. Although it is relatively rare, it is possible for a person to experience both at the same time.
Evidence notes that low sodium levels can occur due to severe cases of hypothyroidism. However, more research is still necessary to better understand the link between both conditions.
This article explores the link between hyponatremia and hypothyroidism in more detail. It also discusses their symptoms and treatment.
Research suggests there is an association between hypothyroidism and hyponatremia, particularly in cases of severe hypothyroidism. As such, health experts may refer to it as
For example, myxedema is a severe form of hypothyroidism than may occur when a person does not receive suitable treatment. While more research is still necessary, research notes that a potential complication of myxedema
Some research highlights that hypothyroidism is a possible cause of euvolemic hyponatremia. This describes when the amount of water in the body increases, but sodium levels remain the same. This causes a dilutional effect of sodium, resulting in hyponatremia.
Evidence suggests that hypothyroidism may cause low sodium levels due to how it affects the kidneys. Hypothyrodism can reduce the function of the kidneys, which can lead to changes with water excretion and how the kidneys handle sodium.
While research notes a link between severe hypothyroidism and hyponatremia exists, the connection in cases of mild hypothyroidism remains less clear. However, doctors may still consider thyroid dysfunction as a potential factor when someone experiences hyponatremia.
Both conditions can cause a variety of symptoms. Some symptoms of hyponatremia and hypothyroidism overlap, while others are more distinct.
Hyponatremia, or low sodium levels in the blood, typically refers to a blood sodium concentration of
Hypothyroidism, or an underactive thyroid, describes when the thyroid gland is
Thyroid hormones play a role in regulating many bodily functions, such as metabolism, growth, and development. As such, the symptoms of hypothyroidism can vary. Common symptoms include:
The treatment options for both conditions differ. However, they both involve addressing the underlying cause of low sodium or thyroid hormone levels and aim to restore them to a suitable range.
Treatment will initially involve restoring blood sodium to a suitable level. This may involve making lifestyle changes or adjusting medication. In more severe cases, a person may require an intravenous sodium treatment to restore their sodium to its typical levels.
A person will also require treatment to address the underlying condition causing hyponatremia. For example, low sodium levels
Managing and treating hypothyroidism
Healthcare professionals may also recommend nutritional changes or supplements to ensure a person has a suitable iodine intake.
Although more research is necessary to understand the link, evidence suggests that hyponatremia can occur due to hypothyroidism. This is likely due to the effect that thyroid hormones can have on kidney function. This can affect how the kidneys process water and sodium, causing euvolemic hyponatremia.
As severe hypothyroidism can cause hyponatremia, doctors may check for an electrolyte imbalance in people with hypothyroidism. In such cases, treatment may involve intravenous sodium, dietary changes, and thyroid medication.
Anyone who suspects they have hypothyroidism or hyponatremia should contact a healthcare professional for further investigation and treatment.
