HI, thanks for using healthcare magic
Diabetes is a progressive condition, medication requirements increase with time.
This can be stalled with lifestyle changes such as using a healthy diet and also getting enough physical activity.
The fact that she is unable to feel on her
limbs implied that there is damage to the nerves in this area. Diabetic nerve disease is a common complication of diabetes.
Decrease sensation can mean that she may not be able to feel if any
injury occurs to the legs which increases the risk of infection.
Preventing
amputation involves: (1)checking the feet completely daily
(2)wearing comfortable shoes that would not cause damage
(3)wearing shoes inside when moving about and outside the house
(4)controlling blood sugars to prevent further damage to the foot and also preventing any other diabetic complications.
I hope this helps
