Yes, hyperthyroidism causes muscle problems. My doctor told me the increased metabolism is like flooring the gas pedal with the car in neutral. A lot of fuel is used, but we don’t go too far. ;) Also, muscle tissue is often burned up by this excess metabolism, so there is less muscle to work with.

Many people notice weak thighs as a sign of hyperthyroidism. I remember before my diagnosis when I went hiking, and could not climb on a rock without feeling like I would fall. I thought at the time I must be getting old.

Hypothyroidism causes another set of muscle problems. I notice this first in my arms, with fatigue from light actions such as lifting my arms or trying to hold on to the steering wheel of a car or brush my teeth.
