Hi There, Thanks for asking. Your mother has elevated blood pressure and it is more than 10 years probably that she is menopause
. She also has history of hypothyoidism. All of the above mentioned issues are the risk factors for sleep apnea
or breathing-related sleep disorder
. Sleep apnea is one of the most common reasons for sleep problem in the elderly. If she is obese
(BMI, more than 30) we can say that she has almost definitely this problem. You can ask your family doctor to introduce your mother to a sleep specialist to assess it more. I wish your mother the best health and longevity in life.
