Hyponatremia disproportionately affects older adults, often due to medications and underlying medical conditions.
Hyponatremia, a condition characterized by low sodium levels in the blood, isn't solely caused by one demographic; however, certain groups are more susceptible. These include:
- Older Adults: As highlighted in the reference, older individuals are at higher risk. This is because they are more likely to:
- Take multiple medications, including diuretics (water pills). Diuretics increase urine production and can flush out sodium.
- Have underlying medical conditions that affect sodium balance.
- Individuals Taking Certain Medications: Diuretics are a prime example, but other drugs can also contribute to hyponatremia. It's crucial to discuss potential side effects with a healthcare provider.
- People with Specific Medical Conditions: Certain medical conditions can impact sodium levels. These include:
- Kidney disease: Impairs the kidneys' ability to regulate sodium.
- Heart failure: Can lead to fluid retention and dilution of sodium.
- Syndrome of inappropriate antidiuretic hormone secretion (SIADH): Causes the body to retain water, diluting sodium.
- Hormonal imbalances: Such as hypothyroidism or adrenal insufficiency.
- Athletes: Endurance athletes who drink excessive amounts of water without adequate electrolyte replacement can develop exercise-associated hyponatremia. This is because excessive water intake dilutes sodium levels in the blood.
In Summary: While hyponatremia can affect anyone, older adults, individuals on certain medications, people with specific medical conditions, and endurance athletes are at a higher risk.
