Myasthenia gravis and hair loss on legs
can myasthenia gravis cause hair loss , muscle loss and cramping of the legs
Myasthenia does not classically cause hair loss, but can be associated with cramping and muscle loss. The muscle loss is secondary to disuse usually. The cramping can be multifactorial: too much Mestinon (pyridostigmine), low Vitamin D levels, low thyroid function, etc. Usually these are secondary causes and not the myasthenia primarily.
When I hear muscle loss, hair loss, and cramping of the legs, I think more about peripheral vascular disease (not enough blood in the legs) and neuropathy (damage to the distal nerves). These could be separate problems related to the myasthenia.
