Low potassium in the elderly.

Potassium is an important electrolyte that is important for nerve and muscle function in the body.

It helps your heartbeat to stay regular.

Potassium is also important for proper cell function.

Cells in our bodies are constantly moving substances in and out of them – waste products are taken out and important nutrients are brought in for instance.

Potassium is crucial for these functions. Thus, without it, different muscle groups and cell function is impaired.

What causes low potassium in the elderly?

Diuretics

Diuretics are commonly-prescribed high blood pressure medication. People who take diuretics have increased urine production. And with increased urination comes the loss of electrolytes like potassium.

Overuse of laxatives

While the occasional use of a laxative is helpful in getting rid of constipation, it is important not to overuse it.

In fact, overusing a laxative causes diarrhea which results in a large loss of water and electrolytes like potassium.

If you or your elderly loved one is experiencing chronic constipation, it’s important to see a doctor about it.

Malnutrition

Malnutrition is a very common cause of low potassium in the elderly.

Diarrhea and excess vomiting

This can be the cause of low potassium as well.

Kidney disease

Chronic kidney disease will also contribute to a low blood potassium level.

What are the symptoms of low potassium?

When potassium levels fall below a certain level, the individual may experience:

• muscle cramps or twitching
• an irregular heartbeat
• weakness
• fatigue
• constipation (which is why it is important to not overuse laxatives!)

If you notice that these symptoms persist, it’s important to see a doctor immediately.

Also, they might treat any underlying disease contributing to this low potassium.
