Hi there ~
I understand your concerns. I understand that you have had surgery for a hiatal hernia
and that your belly button is now non-existent. I also think that losing weight might be a good option for you. I also feel like you would get your finger back from your knuckle if you do so. I also hope you find and get yourself tested by an endocrinologist
for the increased weight, if it does not run in your family.
I hope this helped and I wish you the very best. Take care!
