Hyponatremia in the Elderly: Risks and Solutions

Hyponatremia in the Elderly

Older adults are more likely to get chronic health problems and have an increased risk for hyponatremia, a condition in which insufficient sodium is in the blood. Sodium is necessary for nerve and muscle function, so when levels are low, symptoms can include confusion, weakness, and even seizures. In some cases, hyponatremia can be fatal. Thankfully, there are several steps that older adults and their caregivers can take to help prevent hyponatremia from occurring. Read on to learn more.

What is Hyponatremia?

Hyponatremia is a condition that occurs when the level of sodium in the blood becomes abnormally low. While it can start at any age, it is most common in the elderly. Symptoms of hyponatremia include nausea, vomiting, headaches, muscle weakness, and confusion. In the worst cases, it can lead to coma and death.

Hyponatremia is usually caused by medications or medical conditions that cause the body to lose too much water or prevent the kidneys from adequately regulating sodium levels. However, with proper treatment, most people with this condition make a full recovery. In severe cases, drugs may be required to raise the sodium level in the blood.

What Causes Hyponatremia?

The elderly population is at an increased risk for hyponatremia or low sodium levels in the blood. While it can be caused by several factors, including medications, dehydration, and kidney disease, the most common cause is simply drinking too much water. This can happen if an elderly person is not getting enough salt in their diet or taking diuretics (water pills) that cause them to excrete more water than they take in. Other factors include:

  • Heart failure
  • Excessive thirst
  • Underlying medical conditions

What Are the Risks Associated With Hyponatremia?

Hyponatremia can cause confusion, lethargy, and seizures, leading to coma or death if left untreated. While treatment typically involves IV fluids and close monitoring, severe cases may require hospitalization. The elderly population is also at an increased risk for other complications, such as falls and fractures. As a result, it is essential for those caring for elderly individuals to be aware of the signs of hyponatremia and to seek medical attention immediately if they occur.

What Solutions Are Available to Prevent or Treat Hyponatremia?

There are a few different solutions available for treating or preventing hyponatremia. The most obvious is to make sure that elderly patients are getting enough salt in their diet. This can be achieved by adding salt to food or providing salty snacks. For patients taking diuretics, it is important to monitor their fluid intake and ensure they are not drinking too much water. If necessary, the dose of diuretic can be reduced, or the medication can be switched to another type that does not have the same effect on sodium levels. Some other essential solutions to consider are:

1. Dialysis

Dialysis is a medical procedure that is used to treat hyponatremia by removing excess water from the blood. It can help to improve symptoms and prevent complications. Dialysis can be performed using either hemodialysis or peritoneal dialysis. Hemodialysis involves using a machine to filter the blood, while peritoneal dialysis uses the abdomen’s lining to filter the blood. It is typically performed three times a week for four hours at a time.

2. Sodium Retaining Medicines

While the cause of hyponatremia can vary, it is often treated with medication that helps the body to retain sodium. These medications work by decreasing the amount of water excreted by the kidneys. As a result, the body can keep more sodium in the blood, which helps to raise sodium levels back to normal. While sodium-retaining medications can be an effective treatment for hyponatremia, they should only be used under the guidance of a doctor, as they can also cause dangerous side effects.

3. Intravenous (IV) Fluid

Intravenous (IV) fluid is a medical treatment used to correct an electrolyte imbalance in the body. It is commonly used to treat hyponatremia or low blood sodium levels. When administered IV, the fluid helps to replenish the body’s fluids and electrolytes, restoring them to normal levels. In severe cases of hyponatremia, IV fluid may be given in more significant amounts or for a more extended period of time. This type of treatment is typically administered in a hospital setting, as it requires close monitoring by medical professionals. IV fluid therapy is generally safe, but there are a few potential risks associated with its use. These include allergic reactions to the IV solution, infection at the insertion site, and blood clotting. Despite these risks, IV fluid therapy is an effective treatment for correcting electrolyte imbalances and restoring health.

How Can Family Caregivers Help Prevent or Treat Hyponatremia in Their Loved Ones?

When someone is diagnosed with a chronic or terminal illness, it can be difficult for the whole family to adjust. In addition to the emotional toll, there is also the practical consideration of providing care. One of the challenges that caregivers may face is managing medication and treatments. This is especially true for conditions that require frequent monitoring, such as hyponatremia. However, there are several steps that caregivers can take to help prevent or treat hyponatremia in their loved ones:

  • Ensure that their loved one drinks plenty of fluids throughout the day.
  • Monitor sodium intake and avoid high-sodium foods.
  • Keep track of their loved one’s blood pressure and report any changes to their doctor.

By taking these steps, caregivers can help to ensure that their loved ones remain healthy and comfortable.

Are There Other Considerations to Keep In Mind Regarding Hyponatremia?

There are a few other considerations to keep in mind when it comes to hyponatremia and the elderly population:

  • The elderly are more likely to be on medications that can affect sodium levels.
  • They usually have underlying health conditions affecting sodium levels.
  • The elderly most likely live in environments that can affect sodium levels.

These factors must be considered when treating hyponatremia in the elderly population.


While hyponatremia is a serious condition, it’s also preventable and treatable. By being aware of the risks and taking steps to prevent dehydration in the elderly, we can help reduce the incidence of hyponatremia and improve overall health outcomes for this population.
