My 86 year old mother in law just called me saying she just woke up from a nap but felt cold inside her body...strange feeling....she has atria fib and a weakened heart muscle working at about 1/3 capacity is this feeling cold inside something that is real and should I be concerned about it?
Hello, thank you for putting your trust in our site, my name is Chat Doctor. This feeling of cold inside her body considered a common symptom of atrial fibrillation for females above 60 years old like your mother-in-law, and it happens due to decreased cardiac output to the whole body, so you should not worry about this complaint and assure her that this feeling is normal with her condition and she should be covered while sleeping and wear more clothes. I hope this answer fulfill your query and if you are satisfied with the answer please consider giving 5-star rating, wish you a good health with regards,
