Re: facial weakness/eyelid ptosis
It's weird since the possibility came up for me (and probable diagnosis)... I've noticed my symptoms in other people more and more. I've been told I most likely have something called a mitochondrial myopathy, and your symptoms sound very similar. It's especially sounding suspicious since you have so many multi-organ problems-- pancreas, GI, heart, neuromuscular, ocular... the ptosis sounds about right too, as does the easy fatigue and muscle weakness. I HIGHLY suggest you mention metabolic disease to your doctor. This is pretty rare, or rather, isn't "popular" enough that people are diagnosed with it a lot yet. Hope this helps.
Oh, if you want to know my symptoms:
severe hypoglycemia with some highs
severe progressing spasticity of my legs
writhing/clenching of my muscles
GI issues (GERD, IBS in addition to ulcerative colitis which is in remission, nausea)
These diseases vary from person to person in their presentation based on the type of disease you may have. One person may have heart involvement which another has liver involvement. More organ involvement can happen over time too.
Good luck and please let me know what you find out or if you have questions.
