hypokalemiaa

Hypokalemiaa is not a standard medical term and may be a misspelling of hypokalemia. Hypokalemia, defined as a lower than normal potassium level in the blood, is typically diagnosed when serum potassium falls below 3.5 milliequivalents per liter (mEq/L). Potassium is essential for skeletal muscle function, cardiac conduction, and nerve signaling.

Potassium imbalance alters resting membrane potential in muscle and heart tissue. Most patients with mild hypokalemia are asymptomatic; when symptoms occur they commonly include muscle weakness, cramps, and fatigue. More severe deficiency can cause arrhythmias, constipation, ileus, and, in rare cases, paralysis.

Common causes include gastrointestinal losses from vomiting or diarrhea, renal losses from diuretics, kidney diseases such as Bartter and Gitelman syndromes, and conditions causing effective volume depletion or aldosterone excess. Redistribution from extracellular to intracellular space can occur with insulin administration, alkalosis, or catecholamines. Inadequate intake is less common.

Diagnosis relies on serum potassium measurement, typically alongside evaluation of kidney function and acid-base status. Electrocardiogram changes (for example, flattened T waves, prominent U waves, ST-segment depression) can support the diagnosis and help assess severity. Magnesium deficiency often coexists and should be corrected.

Management depends on severity and symptoms. Mild cases may be treated with oral potassium chloride supplements and dietary potassium; severe or symptomatic cases require careful intravenous replacement with monitored infusion, avoiding rapid correction to prevent hyperkalemia or vein irritation. Correcting coexisting abnormalities (for example, magnesium deficiency) is important.

Prognosis is good with appropriate treatment and management of underlying causes. Recurrence is common if risk factors persist. Prevention focuses on monitoring at-risk individuals (for example, those on diuretics or with renal disease) and addressing contributing factors such as medication effects and gastrointestinal losses.
