Summarize the following:
There are other causes, but these two are the most common by far. Treatment of high potassium will aim to induce potassium loss via excretion through your urine. Start by getting a blood test from your doctor to confirm whether or not you have high potassium. It is a diagnosis that is hard to tell by symptoms alone, so a blood test is very important prior to starting treatment of any sort. Other less common but equally important causes of high potassium are certain "high glucose states" (called "diabetic ketoacidosis") that can occur in the body in severe diabetics, as well as severe injuries to your body, often from an accident of some sort. Because high potassium can be so dangerous to the heart (and because heart symptoms are one of the major ways to diagnose it), your doctor will want to get you an electrocardiogram (a test that evaluates your heart's rate and rhythm pattern) as quickly as possible if your levels are significantly elevated. If your potassium is only mildly elevated, however, your doctors may try a more conservative approach and ask you to come back for a repeat test. The pattern on the electrocardiogram will give your doctor a lot of valuable information on the current state of your heart. This is important not only to help with the diagnosis of high potassium, but also to determine the urgency of treatment, as the state of your heart (and the potential of your heart being in danger from too much potassium) will dictate the strategy your doctors use to lower your potassium. You may be taking a prescription drug that is causing hyperkalemia, or high potassium levels. Your doctor may suggest switching to a new medication or lowering your dose. Also, he or she will suggest to stop taking any potassium supplements or multi-vitamins that contain potassium. If you have very high potassium, your doctor will stop altogether any medications that contribute to elevated potassium that he or she can in the short term, to help speed your recovery. However, discontinuing a medication is not enough on its own to treat severe cases of high potassium, which will need more aggressive methods of treatment. Assuming your potassium is high enough to warrant more aggressive medical treatment, your doctor will ask the nurse to insert an IV line as this can help to deliver the appropriate treatments more effectively and efficiently. Your doctor will likely suggest intravenous calcium, usually 500-3000 milligrams (10-20 mL) one at a time, 0.2 to 2 mL per minute. Your doctor may suggest that you take resin, which will help your body eliminate potassium through the bowels. The typical dose is 50 grams, which can be taken orally or administered in 30 mL of Sorbitol. If your doctor believes it is necessary, you may need to take insulin and/or glucose to move potassium into your cells, where it should be. The usual dose of insulin is 10 units by IV; the usual dose of glucose is 50% (D50W) 50 mL (25 grams). These are typically administered as 1
ampule by IV over 5 minutes, onset in 15 30 minutes for 2 to 6 hours. Diuretics or water pills are sometimes given to remove excess potassium through urination. Diuretics can be taken orally in a 0.5-2 mg dose, 1-2 times/day, or through an intravenous
insertion, in a 0.5-1 mg dose. Your doctor may repeat in 2-3 hours for up to 2 doses if needed. Note that this treatment is not enough for urgent cases, but may be very helpful for more mild cases of elevated potassium. If you are having kidney failure or if you have a significantly elevated potassium level, hemodialysis a process by which a machine removes waste, including excess potassium, from your blood, since your kidneys are unable to do so is your best treatment option. After you have received treatment for your high potassium, it is extremely important to have continual monitoring of your potassium levels to ensure that they stay in a safe and normal range. Normally, patients stay in hospital for a short time after being treated for high potassium, where they can be hooked up to "cardiac monitors" (which monitor your heart function) and otherwise monitored until the doctors determine it is safe to go home. High potassium is a potentially life-threatening condition, especially for the effect it can have on your heart. Therefore, appropriate monitoring with your doctor post-treatment is key. There are times when this extra monitoring can make the difference between life and death, as your doctors can be there to catch any potential "relapse" of elevated potassium. A diet with less than 2g per day of potassium is recommended to prevent relapses of elevated potassium. However, it is important to note that eating high potassium foods is rarely the cause of high potassium levels. As previously mentioned, it is usually caused by kidney disease or medications.

Summary:
Understand that problems with high potassium are generally the result of kidney disease or medication use. Get an electrocardiogram. Review your list of current medications with your doctor. Have an IV inserted. Ask about diuretics. Have hemodialysis. Continue to be monitored by doctors post-treatment. Modify your diet.
