Severe hypokalemia can be life-threatening, especially if it leads to heart arrhythmias or paralysis. If potassium levels drop too low, medical intervention (such as potassium supplements or IV fluids) may be necessary.
Here are the top 10 signs and symptoms of low potassium (hypokalemia):
- Muscle Weakness or cramping, especially in the arms or legs, due to the role of potassium in muscle contractions.
- Feeling tired or exhausted even with sufficient rest.
- Muscle Cramps and Spasms – Sudden, involuntary muscle contractions.
- Heart Palpitations – Irregular or rapid heartbeats (arrhythmia), which can indicate severe potassium deficiency.
- Constipation – Sluggish digestion due to impaired muscle contractions in the intestines.
- Numbness or Tingling – Sensations of pins and needles, especially in extremities.
- Difficulty Breathing – In severe cases, low potassium can affect the muscles responsible for breathing.
- Increased Urination – Frequent urination (polyuria) as the body tries to maintain electrolyte balance.
- High Blood Pressure – Potassium helps regulate blood pressure, and low levels may lead to hypertension.
- Mood Changes – Irritability, confusion, or depression, possibly due to disrupted nerve signaling.
