Hyperkalemia: causes, symptoms, and treatment of the disease
About the symptom
Hyperkalemia is a condition characterized by elevated levels of potassium in the blood, which can cause serious disruptions in the functioning of the body. One of the first and most noticeable symptoms of hyperkalemia is muscle weakness, which can range from mild discomfort to a complete inability to perform usual physical activities. In some cases, patients may notice unexplained fatigue and reduced endurance, which can also be related to disturbances in the electrical activity of muscle cells.
Additionally, patients with hyperkalemia may experience cardiac arrhythmias, which often manifest as palpitations, shortness of breath, or chest pain. If potassium levels become critically high, it can lead to life-threatening conditions, such as cardiac arrest. It is important to remember that the symptoms of hyperkalemia can be subtle or masked by other illnesses, so if this condition is suspected, it is necessary to consult a doctor for diagnostic measures and appropriate treatment.
Diseases
Hyperkalemia is a condition characterized by elevated levels of potassium in the blood, which can be caused by various diseases and disorders in the body. One of the most common diseases leading to hyperkalemia is chronic kidney disease. In this case, the kidneys are unable to effectively remove excess potassium, leading to its accumulation in the blood. Hyperkalemia can also develop in acute kidney injury, which requires immediate medical intervention.
Other diseases contributing to the development of hyperkalemia include diabetic ketoacidosis, Addison’s disease, and certain forms of myocardial infarction. In diabetic ketoacidosis, potassium levels can vary, but in some cases, they may significantly increase due to metabolic dysregulation. Furthermore, the use of certain medications, such as ACE inhibitors and diuretics, can also lead to increased levels of potassium in the body and subsequently cause hyperkalemia.
- Chronic kidney disease
- Acute renal failure
- Diabetic ketoacidosis
- Addison’s disease
- Myocardial infarction
- Hyponatremia
- Use of certain medications (ACE inhibitors, some diuretics)
Diagnosis
The diagnosis of hyperkalemia plays a key role in the timely detection and treatment of this condition. The main method of diagnosis is a biochemical blood test, which allows for the determination of potassium levels in the serum. Elevated potassium levels can indicate not only hyperkalemia but also various diseases that require further investigations. It is important to remember that potassium levels can be temporarily elevated due to stress factors or injuries; therefore, to establish a final diagnosis, it is necessary to consider the clinical picture and the results of additional studies.
In addition, doctors may prescribe an electrocardiogram (ECG) to assess heart function, as hyperkalemia can cause serious changes in its rhythm and conductivity. In some cases, an ultrasound examination of the abdominal organs or kidneys may be needed to rule out other pathologies associated with metabolic disorders and kidney function. A detailed analysis of the patient’s condition will help develop an individual treatment plan and minimize the risks of complications.
- Biochemical blood test
- Electrocardiogram (ECG)
- Ultrasound examination of the kidneys
- Urine test for potassium levels
- Hormone studies regulating potassium levels
Which doctor to contact
If you have symptoms of hyperkalemia, such as muscle weakness, fatigue, irregular heartbeat, or changes in the electrocardiogram, you should see a doctor as soon as possible. Initially, it is advisable to visit a therapist who will conduct a preliminary examination and refer you for the necessary tests. It is important to remember that hyperkalemia can be a consequence of other diseases, so diagnosis and treatment should be comprehensive.
If the test results confirm elevated potassium levels in the blood, the doctor may refer you to more specialized specialists. Depending on the causes of hyperkalemia, these may be endocrinologists, cardiologists, or nephrologists. Each of these specialists has the knowledge and experience necessary to determine the most appropriate treatment method and eliminate the causes of this condition.

- Endocrinologist
- Cardiologist
- Nephrologist
- Dietitian
Types of Hyperkalemia
Hyperkalemia is a condition characterized by elevated levels of potassium in the blood, and it can be divided into several types depending on the causes and mechanisms of its occurrence. The first type is true hyperkalemia, which arises due to impaired kidney function, leading to decreased excretion of potassium in urine. Conditions such as acute kidney failure or chronic kidney disease often become the reason for this type of hyperkalemia.
The second type is pseudohyperkalemia, where the potassium level in the blood appears higher than normal not due to physical reasons but due to errors during blood collection or transportation. This phenomenon can occur, for example, as a result of hemolysis of red blood cells in the test tube, which leads to the release of potassium into the plasma. In such cases, the potassium level becomes normal after a repeat analysis.
The third type is induced hyperkalemia, which develops under the influence of certain medications or diseases, such as diabetes mellitus, which can lead to changes in the distribution of potassium among the body’s cells. Continuous monitoring of potassium levels is especially important for people taking medications that may contribute to increased potassium content in the blood.
- True Hyperkalemia
- Pseudohyperkalemia
- Induced Hyperkalemia
Causes of Hyperkalemia
Hyperkalemia is a condition in which the potassium level in the blood exceeds normal values. There are numerous factors that contribute to the development of this disease. One of the main causes is impaired kidney function, which can lead to a decreased ability of the body to excrete potassium from the blood. For example, acute and chronic kidney diseases, such as glomerulonephritis, can cause potassium retention in the body.
Additionally, hyperkalemia can be a consequence of taking certain medications that affect potassium excretion. Such medications include ACE inhibitors, certain diuretics, and non-steroidal anti-inflammatory drugs. It is also worth noting that excessive intake of dietary sources of potassium or supplements can cause an excess of this mineral in the body, especially in individuals suffering from diseases that disrupt its metabolism.
- Kidney diseases (glomerulonephritis, chronic kidney failure)
- Intake of certain medications
- Excessive potassium consumption
- Acidosis (diseases leading to an acidic state of the blood)
- Increased release of potassium from cells (e.g., due to injuries or burns)
Common Associated Pathologies
Hyperkalemia, a condition characterized by elevated potassium levels in the blood, is often associated with a number of serious pathologies that can negatively impact the overall health of the patient. One of the most common causes of hyperkalemia is chronic kidney disease, in which the kidneys lose their ability to effectively remove potassium from the body. As a result, potassium accumulates in the blood, which can lead to serious consequences, including arrhythmias.
In addition, hyperkalemia may be related to various endocrine disorders, such as hypoaldosteronism, where the level of the hormone aldosterone, which regulates potassium levels, is decreased. It is also worth noting that certain medications, such as ACE inhibitors and diuretics, can contribute to increased potassium levels in the blood. Therefore, patients taking such medications should undergo regular medical examinations.
- Chronic kidney diseases
- Hypoaldosteronism
- Adrenal dysfunctions
- Cardiovascular diseases
- Drug intoxication (ACE inhibitors)
Expert Opinion
Hyperkalemia is a condition caused by elevated levels of potassium in the blood, which can be dangerous to health and even life-threatening. It is important to understand that this disease is often associated with other conditions, such as chronic kidney failure, diabetes, and various cardiovascular disorders. According to specialists, early diagnosis of hyperkalemia is critically important, as high levels of potassium can cause serious disturbances in heart function, which requires immediate intervention.
As emphasized by a nephrologist, one of the main causes of hyperkalemia is impaired kidney function, when they cannot effectively eliminate excess potassium from the body. Additionally, prolonged use of certain medications, such as ACE inhibitors or certain diuretics, can contribute to increased potassium levels in the blood. Therefore, the specialist recommends that patients, especially those with a predisposition to kidney diseases, regularly check their electrolyte levels and undergo appropriate diagnostics.
For effective therapy of hyperkalemia, it is important to consider a comprehensive approach that includes both lifestyle changes and medication treatment. More information about the necessary measures and methods for treating hyperkalemia can be obtained from an experienced specialist who can help choose the most optimal path to restoring health.
Treatment of Hyperkalemia
The treatment of hyperkalemia depends on the severity and cause of the increased potassium level in the blood. In the case of mild hyperkalemia, changes in diet and removal of factors that contribute to the development of the condition may be sufficient to normalize the patient’s state. It is important to pay attention to the consumption of foods rich in potassium, such as bananas, potatoes, legumes, and nuts, and to adjust one’s diet according to the doctor’s recommendations. One should also monitor the intake of medications that may increase potassium levels.
For more severe cases of hyperkalemia, medication may be required. In such cases, the doctor may prescribe medications that help eliminate excess potassium from the body, such as diuretics. In life-threatening situations caused by high potassium levels, urgent hospitalization and methods such as dialysis may be necessary. These procedures help to urgently reduce potassium levels, preventing life-threatening complications.
Methods of treating hyperkalemia:
- Dietary correction
- Medication therapy (diuretics and other drugs)
- Systemic dialysis in emergency cases
- Elimination of causes contributing to hyperkalemia (e.g., treatment of kidney diseases)
- Monitoring and regular blood tests
Complications
Hyperkalemia, characterized by elevated potassium levels in the blood, can lead to a number of serious complications if not diagnosed and treated in a timely manner. One of the most dangerous consequences of high potassium levels is the threat to the cardiovascular system. Excess potassium can cause disruptions in heart function, which may lead to arrhythmias, heart failure, or even cardiac arrest. These conditions require immediate medical intervention, as they can pose a life-threatening risk to the patient.
Additionally, hyperkalemia can cause problems with the nervous system, such as muscle weakness, numbness, and even paralysis. This occurs because potassium is responsible for transmitting electrical impulses between muscles and nerves. An increase in potassium levels can disrupt this process, negatively impacting the motor system. With prolonged hyperkalemia, the risk of complications increases, making it important to monitor potassium levels and consult a professional at the first signs.
- Cardiac arrhythmias
- Heart failure
- Cardiac arrest
- Muscle weakness
- Paralysis
- Kidney dysfunction
