Hyperkalemia is an elevated level of potassium (K +) in the blood. [6] [1] Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels above 5.5 mmol/L defined as hyperkalemia. [3] [4] Typically hyperkalemia does not cause symptoms. [1] Occasionally when severe it can cause palpitations, muscle pain, muscle weakness ...
The high levels of calcium ions decrease the neuron membrane permeability to sodium ions, thus decreasing excitability, which leads to hypotonicity of smooth and striated muscle. This explains the fatigue, muscle weakness, low tone and sluggish reflexes in muscle groups.
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...

High concentrations of potassium (K +) also causes the muscle cells to decrease in efficiency, causing cramping and fatigue. Potassium builds up in the t-tubule system and around the muscle fiber as a result of action potentials. The shift in K + changes the membrane potential around the muscle fiber.
The good news is that focusing on eating more potassium and fiber-rich vegetables like sweet potatoes can support better blood sugar levels, says Shaw. There are endless ways to incorporate more ...
Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]
Treatment includes removing the causative agent (such as licorice), a high-potassium, low-sodium diet (for primary) and high-sodium diet (for secondary), spironolactone and eplerenone, potassium-sparing diuretics that act as aldosterone antagonists, and surgery, depending on the cause. [11] For adrenal adenoma, sometimes surgery is performed.
