Joint inflammation in the hands due to rheumatoid or osteoarthritis can lead to muscle spasms, or cramps, in the adjacent muscles, explains Everyday Health. In addition, the arteries leading to the extremities, such as the hands, often narrow, which leads to cramping.

Poor circulation is a major cause of muscle cramping, which is one reason that diabetics often experience hand cramps since diabetes often leads to poor blood circulation in the limbs, notes Renova Hand Care. Muscle degeneration is another cause of muscle cramps, so people with diseases such as Huntington's disease and multiple sclerosis, in which muscles deteriorate, are prone to developing hand cramps.

Dehydration and low blood levels of potassium, magnesium and calcium as well as deficiencies of certain B vitamins can cause cramps in muscles throughout the body, advises eMedicineHealth. A lack of vitamin D can cause similar issues, states Everyday Health. Because the parathyroid glands regulate levels of potassium, phosphorus and vitamin D in the blood and bones, damage to or removal of these glands can lead to muscle cramps, notes MedlinePlus.
