Overview

Hyperkalemia is a medical condition characterised by elevated potassium levels in the bloodstream. It can disrupt normal heart and muscle function, leading to potentially serious cardiac complications. Potassium is essential for the body for nerves to send and receive signals from the brain, for contraction of muscles, to remove waste from the cells and fill nutrients in them, and to avoid great damage of salt in the body.

Though potassium is vital for the body, an excess amount of the electrolyte may hamper an individual's health. The potassium levels in a human can increase due to improper functioning of the kidneys. The kidneys are responsible for the removal of excess potassium from the body. Still, in case of such medical issues, the kidneys may not be able to remove the potassium properly through urine.

Normal potassium level in an adult is between 3.5 to 5.0 mmol/L. But if the level rises above 5.0, the condition is termed hyperkalemia. When the potassium level reaches 6.5 mmol/L, it is a huge sign indicating different types of heart issues, which should be treated immediately without any procrastination to avoid deterioration of the condition.

Causes of Hyperkalemia

Kidney Disease- One of the major reasons for the disease is the improper functioning of the kidneys. The kidneys are responsible for filtering excess potassium out from the body through urine. But if the kidneys cannot perform this function, then the levels of potassium start rising in the human body.

The kidneys manage the initial stage of the disease. Still, in case of acute conditions, it is recommended to consult a doctor rather than allowing the disease to worsen the functioning of the organ. Potassium levels may also rise in the body due to the high consumption of food rich in potassium or potassium supplements.

Potassium-Rich Diet- Another major reason for the medical issue is the high consumption of foods and supplements full of potassium. Consumption of such foods and supplements is helpful for the body. Still, excess intake of such foods may lead to higher levels of the electrolyte, giving rise to hyperkalemia. Hence, a proper diet chart to manage potassium levels is recommended for people suffering from kidney disease to make it easy for the organ to remove the excess electrolyte. Foods such as bananas and sweet melons are high in potassium and, hence, should be consumed as a dietician recommends.
Diabetes- It may sound surprising to many, but diabetes is also one of the causes of high potassium in an individual’s body. Hence, a person with diabetes is more prone to getting affected by the disease. High blood sugar levels weaken the kidneys and may not allow excess potassium to leave the kidneys. Hence, in the case of such situations, the potassium levels in the body increase, leading to a rise in the symptoms of the disease.
Tissue Injury- Injury, burns, or trauma to muscle tissues can release potassium into the bloodstream.
Addison's Disease-: This adrenal gland disorder can lead to decreased production of aldosterone, a hormone that regulates potassium levels.
Acute Kidney Injury (AKI)- Sudden kidney damage or dysfunction, often caused by conditions such as dehydration, infections, or certain medications, can impair potassium excretion.
Hemolysis- The breakdown of red blood cells can release potassium into the bloodstream.

Symptoms of Hyperkalemia

Abdominal Pain- Abdominal pain is one of the identifiable and common hyperkalemia symptoms. Smooth muscles line the insides of the GI tract. Due to high potassium levels, smooth muscle contractions cannot coordinate with the GI tract. Hence, the affected patient may experience abdominal pain and other similar symptoms, such as vomiting, nausea, and bloating.
Diarrhoea- Another common symptom of the disease is diarrhoea. An individual may feel diarrhoea due to restricted movement of the muscles of the GI tract due to high potassium levels.

Hyperkalemia

Heart Issues- One of the severe symptoms of the disease is different forms of heart issues. High potassium levels may interfere with the functioning of the heart muscles. Symptoms such as slow or fast heartbeats, chest pain, or other heart issues can be identified.
Nausea and Vomiting- Gastrointestinal symptoms such as nausea and vomiting can occur.
Tingling or Numbness- Tingling or numbness, often in the extremities, may be experienced.

Treatment Options for Hyperkalemia

Hyperkalemia treatment differs for each patient depending upon the levels of potassium of each patient. Mentioned below are a few treatment options that can be used to treat the disease:
Medications- One of the commonly used treatment options is medications. They help manage the electrolyte levels and allow one to recover quickly. One may be advised to take diuretics, blood pressure medications, and potassium binders to lower the potassium levels and remove them from the body through urination and defecation.
IV Therapy- Intravenous Therapy involves infusing calcium gluconate, insulin, and albuterol through veins to control the potassium levels in the body. All these liquids are given through the veins at a particular stage and time.
Dialysis- It is a procedure to be followed in case of severe symptoms. The doctors perform dialysis in case of kidney failure. The procedure helps remove damaging, excess potassium from the kidneys for proper functioning of the organ.

Medications for Hyperkalemia

Several medications can help lower potassium levels:

Loop Diuretics: Medications such as furosemide (Lasix) promote the excretion of potassium in the urine.
Sodium Bicarbonate: Used to treat hyperkalemia associated with metabolic acidosis.
Potassium Binders: Medications such as sodium polystyrene sulfonate (Kayexalate) can help remove excess potassium from the body.
Diuretics (Thiazides): In some cases, thiazide diuretics such as hydrochlorothiazide may be used to promote potassium excretion.

When to Consult a Doctor

You can also get in touch with the expert cardiology doctors at Narayana Healthcare based in your city to get immediate attention and medical support during injuries, health disorders or any other health concern.

Conclusion

Hyperkalemia is a medical condition in which an individual faces high potassium levels in the body. It can happen due to a potassium-rich diet or supplements. It can lead to various health problems but can be managed through medications or a surgical procedure.
