<s>[INST] Hello, I have strange sinking spells. I am fine one minute and feel extremely tired the next. I have checked my blood sugar it was 100 after eating. I also stay thirsty. The last time I felt like this I also checked blood pressure and heart rate. Blood pressure was fine 120 over 70. My heart rate was low for what I was doing. It was 55, I was painting a room going up and down a ladder. I just feel weak. My email is YYYY@YYYY [/INST] Hello,Please get assessed, for cardiothoracic status. Get assessed by stress echocardiography and get ECG done. Get your anemia checked. I am sorry, but you did not mention your sex and age as such feature are also seen in 45 plus females as a result of menopause. Hope I have answered your query. Let me know if I can assist you further.Regards,  Dr. Varinder Joshi </s>
