Dehydration: Lack of proper hydration can cause an electrolyte imbalance, leading to muscle cramps and spasms

Mineral Deficiencies: Low levels of minerals like potassium, calcium, and magnesium in the body can contribute to leg cramps.

Poor Blood Circulation: Conditions like peripheral artery disease can restrict blood flow to the legs, increasing the risk of muscle cramps, especially at night.

Nerve Compression: Nerves pinched in the spine (sciatica) or other areas can send signals to muscles, causing cramps.

Medications: Certain medications, such as diuretics, statins, and antipsychotics, list muscle cramps as potential side effects.

Pregnancy: Pregnant women often experience leg cramps due to increased pressure on leg nerves.

Underlying Health Conditions: Conditions like diabetes, thyroid disorders, and kidney disease can contribute to nocturnal leg cramps.
