What are the treatments for the condition?

Treatment depends on the cause. For example, an infection may be treated with antibiotics. An autoimmune disorder may be treated with drugs to suppress the immune system, such as corticosteroids. People with cancer may need surgery, chemotherapy, or radiation therapy. People with a muscle injury may need to apply ice to the muscle, take pain medication and rest.

What are the side effects of the treatments?

Side effects depend on the treatments used. All medications have possible side effects. For example, antibiotics may cause allergic reactions and stomach upset. Corticosteroids can cause weight gain, a puffy-looking face, and weak bones. Surgery carries a risk of bleeding and infection.

What happens after treatment for the condition?

If the weakness goes away or the cause is "fixed," people can usually resume normal activities fairly soon. In other cases, treatment may not end. For example, those with severe heart, liver, or kidney disease usually need treatment for life.

How is the condition monitored?

People can monitor their weakness and how it responds to treatment at home. Further monitoring depends on the cause. For example, those with diabetes need regular check-ups and blood tests.
