7.Pregnancy
There are many signs and symptoms of pregnancy, including fatigue, but muscle weakness generally isn’t one of them. If you have another condition like myasthenia gravis that weakens your muscles, pregnancy might make it worse. See your doctor if you’re pregnant and have muscle weakness you can’t explain. While rare, it could be a sign of a health problem like Guillain-Barré syndrome.
8.Your Doctor Can Help
If it’s hard to do things you used to be able to do because of muscle weakness, see your doctor. They’ll likely do an exam and ask you questions. They may order tests to see how strong your muscles are. The results can help them figure out what’s wrong. They also can help to tell the difference between muscle weakness and other problems you may be having with pain, balance, or endurance.
