The onset of sudden muscle weakness or discomfort can take you by surprise. It may mean you are dehydrated or that your body lacks potassium. However, there are times when muscle weakness, along with other symptoms, may signal the development of a possible chronic condition.

Myopathy is a term the medical community uses to refer to an illness or disease that impacts the muscles. It typically results in the weakening of muscles over time. Some types of myopathy can cause involuntary muscle movement. Depending on the diagnosis, myopathy may result in the immobility of some muscle groups.

1. Causes of Myopathy

There are two main categories of myopathy: acquired and inherited. Acquired myopathy occurs as a result of something else. For example, some autoimmune disorders cause muscle spasms and weakness. When muscles are fatigued or deficient in essential nutrients, myopathy can also occur. Acquired myopathy can happen at any time in a person’s life. It may be temporary or chronic.

Inherited myopathy is genetic. The symptoms may not present immediately at birth, and in some cases, they may come on later in life. However, if a parent or close relative has myopathy, then doctors will likely categorize it as genetic.
