Went to the doctor the other day my blood pressure has always been on the low side, but when he took it the result was 104/47. Lately I am very tired, a little dizzy, and lethargic. I get at least 8-10 hrs. of sleep, but need to take naps lately. I do not eat red meat. I take iron supplements, and eat lots of vegetables, but I am anemic. Any recommendations?
