My husband has no energy, is always very tired and sleeps a lot. I read somewhere that too much sleeping can sap energy. Seems strange, but I don t know how the body works! he has Atrial Fib, which seems to be under control as he has not been in emerg for 3 years. The doctor says he has beginnings of dementia. He failed the memory test, and is now on pills.
Thank you for asking Chat Doctor.  My name is Chat Doctor.  As your husband has cardiac problem firstly you should get focus on this as cardiac issues if not on proper medication can be lethal anytime.It's good to know that he has not been to ER since 3 years.keep proper follow-up visits for this cardiac issues.  Next I would like to clear that energy does not get lost during sleeping as the body metabolism is low during sleep and energy is conserved not lost. Too much sleeping is sign of depression.i don't know exactly the sleeping habit status I mean day time sleeping or anytime...I think you should know his status either he is stressed and depressed or not. Encourage him a lot, spend extra more time with him, I hope he will be feeling fine and get rid of too much sleeping as depression can lead to many mental illness regarding dementia also. Hope this may help you. Let me know if anything is not clear. Thanks.
