Causes of Hypokalemia

Hypokalemia occurs due to various factors, including:

Poor Diet – Not consuming enough potassium-rich foods like bananas, potatoes, and leafy greens.
Excessive Vomiting and Diarrhea – Leads to rapid potassium loss.
Diuretics (Water Pills) – Certain medications increase potassium excretion.
Kidney Disorders – Conditions like chronic kidney disease affect potassium levels.
Excessive Sweating – Loss of electrolytes through sweat.
Hormonal Imbalances – Disorders like Cushing’s syndrome can cause potassium depletion.
Laxative Abuse – Frequent use of laxatives leads to electrolyte imbalances.

Common Symptoms and Signs

Mild hypokalemia may not show symptoms, but moderate to severe cases can cause:

Muscle weakness and cramps
Fatigue and dizziness
Irregular heartbeats (arrhythmia)
Numbness or tingling sensations
Frequent urination
Nausea and vomiting
Breathing difficulties in severe cases

Early diagnosis and treatment prevent complications. If you experience these symptoms, consult a healthcare provider.
