Mild cases of metabolic alkalosis often cause no symptoms. Typical manifestations of moderate to severe metabolic alkalosis include abnormal sensations, neuromuscular irritability, tetany, abnormal heart rhythms (usually due to accompanying electrolyte abnormalities such as low levels of potassium in the blood), coma, seizures, and temporary waxing and waning confusion.
Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma (alkalemia). In contrast to acidemia (serum pH 7.35 or lower), alkalemia occurs when the serum pH is higher than normal (7.45 or higher).
Diagnosis of contraction alkalosis is made by correlating laboratory data with clinical history and examination. Metabolic alkalosis in the presence of decreased effective circulatory volume, loop diuretic use, or other causes of intravascular depletion such as profound diarrhea should raise suspicion for contraction alkalosis as a likely etiology in the absence of other causes.
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]
Common symptoms include hypertension, hypokalemia, metabolic alkalosis, and low plasma renin activity. [1] DOC excess syndrome is an excessive secretion of 21-hydroxyprogesterone also called 11-Deoxycorticosterone from adrenal glands and may cause mineralocorticoid hypertension. [4] [5] [6]
The clinical findings characteristic of Bartter syndrome is hypokalemia, metabolic alkalosis, and normal to low blood pressure. These findings may also be caused by other conditions, which may cause confusion. When diagnosing a Bartter's syndrome, the following conditions must be ruled out as possible causes of the symptomatology: [citation needed]
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 ...
Symptoms include muscle weakness and cramps, paralytic ileus, ECG abnormalities, intestinal paralysis, decreased reflex response and (in severe cases) respiratory paralysis, alkalosis and arrhythmia. In rare cases, habitual consumption of large amounts of black licorice has resulted in hypokalemia.
