Hi,
I am glad to come to know that your mother is in excellent health for her age according to her doctors.
However, she is 94 years old and the metabolic rate is slowing down at this age. Furthermore, although she is taking
thyroid pills, however, their work won't be as efficient as when she was younger.
Being inactive is normal for her age; meanwhile being inactive, could be related to health problems she is having or
malnutrition (lack of appetite/less eating).
With regards to her weight, it might be at least 100 pounds are more, however, I repeat, that is perfect for her age.
All the best to your mom and you too!
Dr.Bardha
Thank you for caring about her!
