Six Steps to Controlling High Potassium

Hyperkalemia occurs when potassium levels in your blood get too high. Potassium is an essential nutrient found in foods. This nutrient helps your nerves and muscles function. But too much potassium in your blood can damage your heart and cause a heart attack. You . Nov 14,  · Often a report of high blood potassium isn't true hyperkalemia. Instead, it may be caused by the rupture of blood cells in the blood sample during or shortly after the blood draw. The ruptured cells leak their potassium into the sample. This falsely raises the amount of potassium in the blood sample, even though the potassium level in your body is actually normal.

Your kidneys help maintain normal blood concentration by removing wastes, excess fluid and electrolytes such as potassium. Potassium, blood urea nitrogen, or BUN, and creatinine blood tests can monitor kidney function in patients diagnosed with kidney disease. High levels of potassium in the blood, elevated BUN and elevated creatinine are all indicators of some degree of kidney dysfunction. The most common cause of high potassium in the blood, or hyperkalemia, is kidney disease, according to MedlinePlus.

Most how to cure whiplash at home the potassium elevatee your body is found inside of your cells, although a small amount circulates throughout your body in your blood. A healthy blood potassium level falls between 3. Normally, your kidneys maintain tight control of the level of potassium in your blood by filtering excess potassium from the blood when needed. When your kidneys are aj working properly, they do not remove potassium from the blood efficiently, causing levels to increase above 4.

When you eat protein, your body breaks it down into its building blocks, which are called amino acids. When protein is broken down, a waste product called nitrogen is produced in the liver. This nitrogen combines with other molecules to create another waste product called whah.

Urea then enters the bloodstream where the kidneys remove it from the body through your urine. A healthy individual has very small amounts of urea in the blood. When the kidneys are not functioning properly, they do not remove urea, and levels accumulate in the blood. A blood urea nitrogen, or BUN, test measures the amount of urea in your blood. Elevahed healthy BUN usually falls between 7 and 20 milligrams per deciliter.

If your BUN level exceeds 20 milligrams per decilliter, it can indicate kidney disease. Your muscles use a compound called creatine in order to what is a professional website. Every time your muscles contract, creatine is broken down and a waste product called creatinine is produced.

This creatinine enters your blood and travels elevafed your kidneys, where almost all of it is removed by your kidneys.

A normal blood creatinine level falls between 0. Elevated levels of creatinine in the blood indicate that the kidneys are not functioning normally.

Although potassium, BUN and creatinine tests can determine if your kidneys are not functioning normally, they cannot isolate the cause of the kidney dysfunction. Abnormal values can occur as a result of acute kidney failure, chronic kidney failure, glomerulonephritis and urinary tract obstruction. If your lab values come back abnormal, your doctor may recommend further testing to isolate the cause of your kidney disease. Lindsay Boyers.

Oct 20,  · This is called hyperkalemia, or high potassium. According to the Mayo Clinic, a normal range of potassium is between and millimoles per liter (mmol/L) Author: Carmella Wint. Jul 20,  · When you have kidney disease, your kidneys cannot remove extra potassium in the right way, and too much potassium can stay in your blood. When you have too much potassium in your blood, it is called high potassium, or hyperkalemia. Having too much potassium in your blood can be dangerous. High potassium can even cause a heart attack or death! Dec 08,  · A high potassium level can indicate your kidneys aren’t functioning usloveescort.comted Reading Time: 1 min.

Potassium is essential to many vital processes in the body. Potassium is involved in the proper functioning of nerve and muscle cells, digestion, metabolism and maintaining the balance of both electrical and chemical processes in the body.

Potassium is especially important in cardiac function. Normal serum potassium levels range between 3. A high level of potassium in the blood is often indicative of an underlying kidney dysfunction. High blood potassium, or hyperkalemia, often indicates that the body is producing too much potassium or that the kidneys can no longer remove excess potassium properly. Hyperkalemia can indicate kidney failure, infection, obstruction or even a transplant rejection.

The hormone aldosterone regulates how the kidneys remove excess sodium and potassium. A lack of aldosterone can lead to an elevation of blood potassium, according to the National Institutes of Health 1.

Anytime potassium releases from the cells it can raise potassium levels. A condition known as acidosis will move potassium from inside the cells to the fluid outside. Tissue injuries such as burns, traumatic injury, hemolytic conditions in which blood cells burst and muscle breakdown can all lead to acidosis and increased serum potassium. A slight elevation in serum potassium will often not cause symptoms.

However, when potassium increases, it causes disturbances in electrical functions of the body, interfering with the heart's ability to beat properly. The University of Maryland Medical Center explains that as potassium increases, people are likely to notice muscle aches and cramps, fatigue, weakness, difficulty breathing, irregular heartbeat, nausea, and weak or absent pulses.

Elevated serum potassium can lead to life-threatening complications including paralysis, cardiac arrest and death. Commonly, the medical staff will run a panel of all electrolytes as well as test kidney and liver function.

Elevated serum potassium does not necessarily mean that the kidneys are malfunctioning or that there is an underlying disease process at work. In some cases, an elevated blood potassium level can appear falsely elevated.

Physicians will often retest if an error is suspected. Lab Tests Online explains that clenching and relaxing the fist repeatedly during collection of the sample can cause a false elevation 2. Improper testing of the blood by the lab can also lead to a false elevation, as can allowing the sample to sit at room temperature for too long prior to testing.

Crying or rapid, shallow breathing can also lead to a false elevation. If physicians confirm a diagnosis of hyperkalemia, treatment will involve not only treating the underlying condition but also balancing potassium levels.

Calcium chloride or gluconate will help to minimize the effects of the excess potassium on the heart. Insulin, sodium bicarbonate and beta agonists will all help to promote the shift of potassium from blood to cells, according to the University of Maryland Medical Center.

Diuretics can help promote excretion of excess calcium from the kidneys. Based in Florida, Martina McAtee has been writing health and fitness articles since She attended Keiser University, graduating with an Associate of Science in nursing.
