[|Human|] This is a question for my mom. She has been sickly since I was a kid, she was once diagnosed with MS but was told she didnt have it. Now she is very frail looking, her sympotoms are: very weak ( she says her body feels like a weat noodle), heart rythm will beat really fast or slow, she also has fainting spells. She has seen a cardiologists they say her heart is just fine. What do you think just with very little I have told you? Thank you in advance for any info.
[|AI|]  Hello! Welcome on Chat Doctor ! I read carefully your question and understand your concern. Her symptoms could be related to different possible causes: a cardiac arrhythmia, orthostatic hypotension, thyroid dysfunction, vitamin D deficiency or vitamin B12 deficiency, epilepsy seizures, etc. I would like to directly review her brain MRI. It is also necessary performing further tests: - an EEG - complete blood count for anemia-blood electrolytes- a rhythm Holder monitoring for cardiac arrhythmia-vitamin D and Vitamin B12 plasma levels - a Head Up Tilt test for orthostatic hypotension- fasting glucose and thyroid hormone levels. A new brain MRI may be necessary, especially if it has passed a long time since her last one. You should discuss with her doctor on the above tests. Kind regards,
