I have been on
Synthroid and Thyroid (Armour) for hypothyroidism for two years. I have very weak, thin, finger nail
s that break or split horizon
tally and/or vertically, moon
my thumb and 1st finger
s, multiple thin ridges going up and down on
beds & a few fingernail
s that are flat
or bend under.
I also have mitral valve prolapse with regurgitation
- grade 3. Are my fingernail
s indicative of either my thyroid or heart problem?
