I have always been a person who goes to bed around midnight and up at 6 eager to face my day. The past 3 weeks or so, I have felt tired and lethargic. Going to bed between 9 and 10:30 awake at 6. but back to sleep until 8. Getting out of bed feeling exhausted. I am 56 years old. I have recently experienced some lower abdomen issues (cramping and loose stool) That seems to have passed, but the rest remains. I do have a family history of heart issues, as my Father and all his brothers died of heart attacks.
Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. Forum.  You are 56 years old, usually sleeps at midnight and wakes up at 6 am, recently you became tired and lethargic, sleep timings became irregular, You had some lower abdominal issues, cramping and loose motions. You have a family history of heart disease, M.I. At the age of 50+. People will have a decline in hormones level, It can cause tremendous changes like this.  You had stomach pain and loose motions, with these symptoms anyone will get the weakness, for this medication and infusion of the fluids are required, if not treated properly can have such changes.  Heart issues will be presented with different symptoms, so don't worry about it, if you go on thinking about it, you can get the symptoms of heart disease, though not the disease. So try to avoid it.  I advise you to consult a doctor for diagnosis and treatment, with medicines and infusions.  Wishing for a quick and complete recovery.  Best regards.
