Hypokalemia is a low level of potassium (K +) in the blood serum. [1] Mild low potassium does not typically cause symptoms. [3] Symptoms may include feeling tired, leg cramps, weakness, and constipation. [1] Low potassium also increases the risk of an abnormal heart rhythm, which is often too slow and can cause cardiac arrest. [1] [3]
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 ...
The pathophysiology of hypertension is an area which attempts to explain mechanistically the causes of hypertension, which is a chronic disease characterized by elevation of blood pressure. Hypertension can be classified by cause as either essential (also known as primary or idiopathic) or secondary. About 90–95% of hypertension is essential ...
Over time, this pressure can cause small tears in your arteries. Plaque can collect in and around these tears, causing your arteries to narrow and obstructing the flow of blood to and from your ...
PHA2 also known as Familial hyperkalemic hypertension or Gordon syndrome is a rare disorder characterized by abnormalities in how the body regulates sodium and potassium levels. This condition stems from mutations in specific genes involved in the regulation of sodium transport within the kidneys.
In patients with hypertension, diagnostic clues pointing to pseudohyperaldosteronism can be found on routine labwork. These include low serum potassium (hypokalemia), elevated serum sodium (hypernatremia), and elevated serum bicarbonate (metabolic alkalosis). [1] Urine studies may show elevated urine potassium . To further differentiate between ...
Cortisol at high concentrations can cross-react and activate the mineralocorticoid receptor due to the non-selectivity of the receptor, leading to aldosterone-like effects in the kidney. This is what causes the hypokalemia, hypertension, and hypernatremia associated with the syndrome. Patients often present with severe hypertension and end ...
