What Causes High Potassium Levels in the Elderly? As people age, kidney functions change. Once blood flow starts decreasing, the kidneys' ability to filter the incoming blood also decreases. The result is a slower excretion of potassium, which can lead to hyperkalemia.
The most common cause of genuinely high potassium (hyperkalemia) is related to your kidneys, such as: Acute kidney failure. Chronic kidney disease.
Medications. Diuretics and potassium binders are two common types of medication that can treat hyperkalemia. Diuretics increase the flow of water, sodium, and other electrolytes like potassium out of the body. They're a common part of treatment for both acute and chronic hyperkalemia.
Additional medications that can lead to high potassium levels include angiotensin-converting enzyme inhibitors, beta-adrenergic blockers, heparin and high doses of digoxin. These hyperkalemia risk factors associated with medications are further compounded by the decreased function of aging kidneys.
Having too much potassium in your blood can be dangerous. Potassium affects the way your heart's muscles work. When you have too much potassium, your heart may beat irregularly, which in the worst cases can cause heart attack. If you think you are having a heart attack, call 911 for emergency help.
Your provider may recommend binders if other treatments don't lower potassium levels. Potassium binders come in oral and enema form. Dialysis: If potassium levels remain high, or you experience kidney failure, you may need dialysis. This treatment helps your kidneys remove excess potassium from blood.
What should I include in my diet to help lower potassium? If you have hyperkalemia, doctors will advise you to avoid certain foods that are high in potassium. You can also make sure to drink plenty of water. Dehydration can make hyperkalemia worse.
Potassium is a chemical that is critical to the function of nerve and muscle cells, including those in your heart. Your blood potassium level is normally 3.6 to 5.2 millimoles per liter (mmol/L). Having a blood potassium level higher than 6.0 mmol/L can be dangerous and usually requires immediate treatment.
Can Hyperkalemia be treated? Yes. You may need to follow a low-potassium diet. Your healthcare provider will tell you if any changes in your medicines are needed.
Hyperkalemia is occasionally induced by chemotherapy for very large malignant tumors, due to tumor lysis syndrome. Hypercalcemia and hyponatremia are often observed in patients with breast cancer, renal cancer, prostate cancer, and the like, as a paraneoplastic syndrome.
Boiling potatoes and vegetables will reduce their potassium content as some of the potassium leaks into the cooking water. Potatoes that have been par-boiled (partly cooked by boiling) can then be fried, roasted or added to casseroles if desired. Try not to use cooking water to make gravy, stocks or soups.
Studies have found that anxiety increases adrenal hormones, which can decrease blood potassium [17]. Avoid or manage stress. Good strategies to manage stress are getting adequate rest, engaging in exercise, relaxation, meditation, etc. Discuss supplemental potassium with your doctor.
Severe hyperkalemia is a medical emergency and can lead to significant morbidity and mortality; it therefore requires hospitalization, ECG monitoring, and immediate treatment [16].
Complications from high potassium
If left untreated, high potassium levels can lead to the following complications: weakness. arrhythmia, a heart disorder that affects the rate or rhythm of your heartbeats. heart attack.
High potassium levels may be a sign of: Kidney disease. Your kidneys remove extra potassium from your body. Too much potassium may mean your kidneys aren't working well. Addison disease, a disorder of the adrenal glands.
Vitamin D3 tended to increase retention of both potassium and sodium in the body. A significant interaction occurred between dietary magnesium and vitamin D3 relative to body weight gain. Vitamin D3 increased magnesium content in tibiae ash and decreased magnesium content in serum.
Typical patients with hypokalemia have required a mean of 5 days for return of their serum potassium levels to normal (12,13).
