Muscular dystrophy (MD) refers to a group of more than 30 inherited diseases that cause muscle weakness and muscle loss. Some forms of MD appear in infancy or childhood, while others may not appear until middle age or later. The different muscular dystrophies vary in who they affect and the symptoms. All forms of MD grow worse as the person's muscles get weaker. Most people with MD eventually lose the ability to walk. There is no cure for muscular dystrophy. Treatments include physical and speech therapy, orthopedic devices, surgery and medications. Some people with muscular dystrophy have mild cases that worsen slowly. Other cases are disabling and severe.
Muscular dystrophy (DIS-trah-fee) is also called MD. It is a genetic disease that can affect different groups of muscles in your body. A genetic disease is one that you may inherit from your family and may pass on to your children. MD may also be a condition that you are born with. MD causes the muscle cells to die. This results in the muscle becoming weak, small, and deformed. MD may also affect other parts of your body, such as your heart, lungs, eyes, and brain. There are many types of MD. Each type may have different muscles that may be affected.
Muscular dystrophy (MD) is a genetic (inherited) condition that over time gradually causes the muscles to weaken. This leads to an increasing level of disability.

Muscle cramping in different parts of the body is commonly caused by a calcium and magnesium imbalance and/or a vitamin E deficiency. Anemia, arthritis, and even arteriosclerosis may result in cramping. Most muscle cramps occur at night when resting and affect the legs, especially the calf muscles, and the feet. These kinds of cramps occur more frequently in the elderly, the young, and persons with arteriosclerosis. The use of diuretic drugs for high blood pressure or heart disorders may also be the cause of muscle cramping. If taking one of these drugs, be sure to add potassium. Poor circulation contributes to leg cramps. See the doctor if you have cramps during the day while active. This may be a sign of impaired circulation.
