Fearing leaks IS part of Hillary’s medical problems.
With a leaky heart valve and Hypothyroidism I suspect she also has an Enlarged Heart. Both contribute to extreme fatigue.
I have an enlarged heart with a sm leaky valve, they do not replace it until it reaches a certain value of leakage. She is Hypothyroid just as I am, and it is common for us to have a leaky heart valve. http://www.webmd.com/heart/news/19991130/heart-valve-defect-common-patients-thyroid-disease
She is not on Synthyroid but the Armour Thyroid treatment which is the original and natural form. Takes a lot more testing to get it right done by an ENDO not an Internist. To little OP and fatigue are big issues same as to much. Which may account for her being handled so she won’t fall and break a hip exposing her to a hip replacement and her other health issues getting exposed.
Those blood clots don’t go away with a chem blood thinner either. Those long sleeves and pants cover up the severe bruising they cause.
