Introduction
The normal range for serum potassium electrolyte is 3.5–5.5 mmol/L. Potassium is an inorganic cation in the human body, primarily found in bone and extracellular fluid. When potassium levels remain stable within the body, it plays important roles in regulating cellular metabolism and maintaining the resting membrane potential of cells. If a patient experiences physical discomfort, prompt medical evaluation at a hospital is necessary.
Under normal circumstances, the normal range for the electrolyte potassium is 3.5–5.5 mmol/L. The detailed analysis is as follows:
Potassium is an inorganic cation in the human body with a normal range of 3.5–5.5 mmol/L. It is primarily present in bones and extracellular fluid. When potassium levels in the body remain stable, it plays important roles such as regulating cellular metabolism and maintaining the resting membrane potential of cells. If a patient has insufficient potassium intake over a prolonged period, leading to low potassium levels, symptoms such as muscle weakness, abdominal distension, arrhythmia, and difficulty breathing may occur. Conversely, if potassium levels become too high, the patient may experience weakness and numbness in the limbs, and in more severe cases, paralysis may develop.
For patients with low potassium levels, increasing dietary intake of potassium-rich foods in daily life is recommended. Additionally, under medical supervision, medications such as potassium citrate granules or potassium chloride sustained-release tablets can be used for treatment. For individuals with elevated potassium levels, treatment at a hospital under a doctor's guidance may include medications such as sodium bicarbonate injection or chlorothiazide tablets.
When experiencing physical discomfort, patients should promptly visit a hospital for examination and timely treatment to prevent disease progression and more serious bodily harm.
