Common Causes of Nighttime Leg Cramps
-
Dehydration
When your body lacks enough fluids, muscle cells become more prone to contractions, making cramps more likely to occur at night. -
Electrolyte Imbalance
Low levels of potassium, magnesium, calcium, or sodium disrupt normal muscle function and can trigger painful spasms. -
Poor Circulation
Reduced blood flow to the legs, often caused by sitting or standing for long periods, may lead to cramps during sleep. -
Nerve Compression
Conditions such as spinal issues or nerve pinching can irritate the muscles and cause nighttime cramping. -
Medication Side Effects
Certain drugs, including diuretics, statins, or blood pressure medications, may increase the risk of cramps. -
Medical Conditions
Diabetes, thyroid disorders, or vascular diseases can present with frequent muscle cramping as an early symptom.
