High potassium (hyperkalemia): Symptoms, causes, and prevention

Hyperkalemia is the medical time period for when an individual has larger than regular ranges of potassium. Normally, individuals with hyperkalemia do not need any signs, which makes it difficult for a health care provider to diagnose.

The main causes of hyperkalemia are continual kidney illness, uncontrolled diabetes, dehydration, an damage inflicting extreme bleeding, consuming extreme dietary potassium, and a few medicines. A health care provider will usually diagnose hyperkalemia when a person’s potassium ranges are larger than 5.0–5.5 milliequivalents per liter.

Remedy for hyperkalemia varies in line with severity. In acute hyperkalemia, which regularly outcomes from a selected occasion, reminiscent of trauma, docs could use dialysis and intravenous medicines to flush the potassium from the physique. Power hyperkalemia often implies that an individual’s kidneys should not functioning accurately, and docs will provide remedy to handle the situation.

On this article, we are going to focus on the causes, signs, and remedy choices for hyperkalemia.

Hyperkalemia describes a medical situation during which an individual has an excessive amount of potassium of their blood. Usually, the physique’s kidneys are capable of regulate its serum focus of potassium. Nevertheless, if the kidneys should not functioning effectively, potassium can accumulate within the blood. Most sources recommend that ordinary potassium serum ranges are between 3.6–5 millimoles per liter, and ranges above 5 mmol/l point out hyperkalemia.

Potassium is among the seven essential macrominerals that individuals require for optimum well being. It performs an important role in lots of bodily features, reminiscent of serving to the kidneys, coronary heart, muscle mass, and the transmission of messages via the nervous system.

Nevertheless, whereas it’s important that individuals eat a ample quantity of dietary potassium, having an excessive amount of current within the blood may end up in well being issues. In accordance with the Office of Dietary Supplements (ODS), the sufficient consumption stage for potassium is roughly 2,600–3,400 milligrams for many adults and a every day worth of 4,700 mg for adults and kids age 4 years and older

There are totally different causes of excessive potassium ranges, most of which have an effect on the operate of the kidneys. Doable causes of hyperkalemia may include:

  • Power kidney illness: A decrease kidney capability implies that the kidneys could not be capable to filter potassium out of the physique adequately.
  • Uncontrolled or untreated diabetes: As a lower in kidney operate is a attainable complication of diabetes, poorly managing the situation may result in hyperkalemia.
  • Taking certain medications: Nonsteroidal anti-inflammatory medication (NSAIDs), reminiscent of ibuprofen and naproxen, potassium-sparing diuretics, cyclosporine, trimethoprim, angiotensin-converting enzyme (ACE) inhibitors, beta-blockers, calcium channel blockers, succinylcholine, digoxin, heparin, and mannitol might also forestall the kidneys from eliminating extra potassium.
  • Coronary heart illness: In individuals with congestive coronary heart failure, decrease kidney operate mixed with the treatment to deal with the illness could cause hyperkalemia.
  • Harm: Burns or different extreme accidents could cause injury to tissues that ends in the physique releasing additional potassium into the blood.
  • Hypoaldosteronism: This uncommon situation ends in a scarcity of aldosterone. This hormone helps regulate the quantity of potassium the physique excretes within the urine. Individuals might also expertise pseudohypoaldosteronism, which mimics the situation.
  • Congenital adrenal hyperplasia: A uncommon illness ensuing from a gene mutation that may additionally cause decrease ranges of aldosterone.
  • Addison’s disease: It is a situation that happens following injury to the adrenal glands. It might have an effect on the manufacturing of hormones, reminiscent of aldosterone and cortisol, which may have an effect on potassium ranges.
  • Greater potassium consumption: Consuming an excessive amount of potassium via medicines or weight-reduction plan could cause hyperkalemia. That is uncommon however could have an effect on individuals whose kidneys don’t operate optimally.
  • Pseudohyperkalemia: This happens when an individual receives a falsely high potassium studying. This will likely occur when utilizing a syringe or different strategies that trigger hemolysis, which is the breakdown of purple blood cells.
  • Dehydration: Extreme dehydration could result in the physique being unable to course of potassium.

Usually, an individual with hyperkalemia will expertise very few, if any, signs. The signs they could expertise are sometimes delicate and nonspecific, which implies that docs could overlook it till signs worsen.

Hyperkalemia happens when the physique is unable to take away extra potassium. As an electrolyte, it helps regulate fluid and blood ranges, muscle contractions, and nerve impulses. As such, excessive ranges of potassium could disrupt or have an effect on many of those processes.

Acute hyperkalemia is when vital modifications to potassium ranges happen over a short while, and it’s extra severe than having continual hyperkalemia, or frequently excessive potassium ranges. Nevertheless, each acute and chronically excessive potassium ranges will be harmful, doubtlessly inflicting a coronary heart assault or paralysis.

Power hyperkalemia usually has fewer signs than acute hyperkalemia.

At larger potassium ranges, signs of hyperkalemia can include:

  • muscle weak point
  • a common feeling of weak point or fatigue
  • nausea and vomiting
  • muscle ache or cramps
  • problem respiratory
  • coronary heart palpitations
  • chest ache

Hyperkalemia usually presents with no symptoms. This implies docs usually discover it difficult to diagnose.

In individuals with circumstances of acute hyperkalemia, docs will:

  • assess kidney, coronary heart, and urinary tract operate
  • verify hydration ranges
  • monitor the heartbeat utilizing an electrocardiogram

In individuals with circumstances of continual hyperkalemia, docs observe up by ordering routine laboratory work, reminiscent of blood exams or urine samples. Moreover, they could verify medicines to make sure there aren’t any interactions that will contribute to excessive potassium ranges.

Medical doctors usually use dialysis to deal with individuals with circumstances of hyperkalemia that require pressing remedy. Dialysis entails filtering the blood to get rid of toxins, and it’ll scale back the physique’s complete potassium ranges. Individuals with kidney failure or pressing circumstances of hyperkalemia will profit probably the most from dialysis.

In acute hyperkalemia, docs could prescribe the next treatments to decrease potassium ranges:

  • Intravenous insulin and glucose: That is probably the most dependable technique for decreasing potassium ranges because it forces potassium into the cells and out of the blood. Typically, this selection works inside 10–20 minutes and the impact usually lasts 4–6 hours. The glucose helps forestall blood sugar ranges from going too low.
  • Albuterol: That is solely efficient in some teams of individuals. Medical doctors usually administer a a lot larger focus than a typical albuterol inhaler, they usually could use it alongside different therapies to assist with potassium secretion.
  • Intravenous calcium: Injecting calcium into the blood helps to stabilize the cardiac membrane, which can assist shield towards injury to the guts.

Remedy choices for chronic hyperkalemia could embody stopping or adjusting medicines, avoiding NSAIDs, and decreasing the consumption of meals wealthy in potassium. Moreover, individuals could benefit from avoiding sure salt substitutes, natural cures, or dietary supplements and taking diuretics and potassium binders.

If an individual is in danger for creating hyperkalemia, they’ll make some dietary alterations that will assist forestall their potassium ranges from changing into too excessive. Nevertheless, earlier than making any modifications, it’s advisable to debate them with a health care provider.

For instance, a health care provider may suggest limiting meals that include excessive ranges of potassium. In accordance with the Dietary Guidelines for Americans, the meals with the very best potassium per serving measurement are:

  • stone fruits, notably dried prunes, apricots, and peaches

Along with limiting or avoiding sure meals, individuals may also:

  • verify if any salt substitutes are excessive in potassium, reminiscent of people who record potassium chloride as an ingredient
  • drink ample quantities of water to keep away from dehydration
  • keep away from sure herbs that may elevate potassium ranges, reminiscent of alfalfa, nettle, and dandelion

Remedy for hyperkalemia varies in line with whether or not it’s acute or continual. Acute hyperkalemia is extra pressing and harmful than continual hyperkalemia and requires speedy remedy, reminiscent of dialysis.

Some teams of persons are extra prone to expertise hyperkalemia. Being older or male can improve the danger of hyperkalemia. Having kidney illness, hypertension, diabetes, coronary heart illness, or a previous coronary heart assault might also improve the danger of creating hyperkalemia.

Speaking with a health care provider is step one to forestall hyperkalemia and discover efficient remedy.
