What Are Some Causes of Hand Cramps and Spasms?
There are many possible causes of hand cramps and spasms including dehydration, thyroid conditions, abnormal levels of electrolytes or minerals, nerve damage, and hyperventilation, according to MedlinePlus. The cause of muscle cramps and spasms is often not clear.
Additional possible causes of hand cramps and spasms are vitamin D deficiency, pregnancy and certain medications, also per Medline Plus. Chronic kidney disease and dialysis may also be a cause. Another possible cause is a brain disorder, such as Parkinson’s disease, dystonia, Huntington’s disease and multiple sclerosis.
Hand cramps can also be caused by muscle overuse, muscle strain, holding a prolonged position, nerve compression and inadequate blood supply, as stated by Mayo Clinic. An individual should drink plenty of liquids each day and stretch before prolonged muscle use. Light exercise may also help prevent cramps if they occur when sleeping.
Regular physical activity, strength-building exercise and aerobic exercise are additionally helpful to prevent muscle cramps, reports Medline Plus. However, an individual must avoid over-exertion and be sure to stay hydrated throughout exercise.
An individual should contact a health care professional if the hand spasms are recurrent, according to MedlinePlus. The doctor may determine the cause through testing the individual’s kidney function, hormone levels, vitamin D level and various mineral levels. The doctor may recommend vitamin D or calcium supplements if vitamin D or mineral deficiency is the cause.
