How is the condition diagnosed?

Figuring out the cause of weakness starts with a history and physical exam. In some cases, this may be all that the healthcare provider needs to make a diagnosis. In other cases, further testing is needed.

Which tests are done depends on the suspected cause. For example, blood tests such as a chem-7 can be used to diagnose salt imbalances. Chest x-rays may show pneumonia, and cranial CT scans can help detect a stroke. Special nerve and muscle tests, such as an electromyogram or nerve conduction velocity test, may help diagnose myasthenia gravis or diabetic neuropathy. Other tests may be needed as well.
