Every cell, tissue and organ in your body requires potassium to function properly. Seniors need the same amount of potassium a day as younger adults; this can be accomplished by consuming a healthy, balanced diet. As you age, your risk for developing high potassium levels, or hyperkalemia, increases as your kidneys become less efficient. So it is essential to talk to your doctor before you begin consuming more potassium, particularly in supplement form.
Function and RDA
As an electrolyte, potassium transmits electricity throughout your body, while working with other minerals like calcium, chloride, sodium and magnesium. Your skeletal and muscle movements depend on this mineral as well, as does your digestive system. The electrical activity in your heart requires potassium to function, too, and it is also essential for energy production. According to MedlinePlus, the Food and Nutrition Center of the Institute of Medicine recommends that adults of all ages need 4.7 g of potassium a day.
Older Adults and Risks of Hyperkalemia
Having too much potassium in your blood can pose risks, such as the development of hyperkalemia. As you get older, your kidneys cannot eliminate potassium as effectively as they once did, and this increases your risk of overdosing on the mineral. Furthermore, if seniors take medications such as nonsteroidal anti-inflammatory drugs or ACE inhibitors, this can result in a rise in your potassium levels as well. Symptoms of hyperkalemia include muscle fatigue, weakness, nausea, an irregular heartbeat and even paralysis. Seek medical attention if you suspect you have this condition.
Food Sources and Supplements
If you eat a nutrient-rich diet, you can most likely meet your needs for potassium through food. Good fruit and vegetable sources of this mineral include citrus juices, avocados, broccoli, cantaloupes, tomatoes, peas, bananas, prunes and potatoes. Dairy products such as milk and yogurt, as well as flounder, chicken and cod, contain significant amounts of potassium, too. If you do not or cannot eat a balanced diet, your doctor may suggest potassium supplements. These should only be taken under the supervision of a licensed medical professional, however, particularly if you are a senior. Inform your physician if you experience any adverse symptoms while on the supplements.
Additional Considerations
While too much potassium is dangerous, low intake can result in low potassium levels, or hypokalemia. This is most often temporary and a side effect of an illness that causes vomiting or diarrhea. Some of the medications you may be on, however, can also decrease the levels of this mineral in your blood, such as diuretics, corticosteroids, insulin and laxatives. If you are taking these, it is important for your doctor to test your potassium levels to determine if supplementation is required.
