Nocturnal cramps (nighttime muscle cramps, often in the legs or feet) can happen to anyone, but some people are more likely to experience them.
People at higher risk include:
- Older adults
Night cramps become more common with age, partly due to changes in muscles, nerves, circulation, and activity levels. - People who are very active or exercise intensely
Heavy exercise, overuse of muscles, or sudden increases in activity can trigger cramps. - People who are dehydrated
Not drinking enough fluids—especially with heavy sweating—may contribute to muscle cramping. - Pregnant people
Leg cramps are common during pregnancy, particularly later in pregnancy. - People with certain medical conditions
Conditions that may be associated with cramps include:- Diabetes (especially if nerve damage is present)
- Kidney disease
- Thyroid disorders
- Circulation problems
- Nerve disorders
- People taking certain medications
Some medicines can increase the likelihood of cramps, including certain diuretics (“water pills”) and some cholesterol-lowering medications. If cramps begin after starting a medication, discuss it with a healthcare professional rather than stopping it on your own.
