People most likely to experience nighttime leg cramps include:
- Older adults — muscle mass and flexibility tend to decline with age.
- Pregnant people — especially later in pregnancy.
- People who exercise intensely — overworked or fatigued muscles can cramp.
- People who stand or sit for long periods — prolonged muscle positioning may contribute.
- People who are dehydrated — particularly after heavy sweating.
- People with certain medical conditions — including peripheral artery disease, nerve disorders, diabetes, and kidney disease.
- People taking certain medications — some diuretics and other medicines can contribute to cramps.
- People with poor circulation or nerve compression — these can increase the likelihood of nighttime symptoms.
Occasional cramps are usually harmless. Frequent, severe, or worsening cramps, especially when accompanied by swelling, weakness, numbness, or skin color changes, deserve medical evaluation.
