During the last year my blood pressure has been in the low numbers (95/57). I have been suffering from severe headaches almost feeling faint, very tired, blurred vision (feels like my eyes are dilating), and nauseous - this happens about 5 days out of the week. I experienced external hemorrhoids w/o blood twice last summer and internal hemorrhoids with blood twice at the beginning of this year. I am a 31 year old female 5 3 152lbs who has always been pretty healthy. Now more than 3 hours without eating and I feel faint. Been to my doctor who drew blood and all was ok except that my iron is bordeline yet my blood count is higher than normal and I was not dehydrated. He suggested increasing my salt intake and cutting out caffeine. I havery increased my salt intake dramatically and I have one cup of 1/2 decaf and 1/2 caf a day 5 days a week. Been to an ent and neurologist and all was fine. What could possibly be the cause of my low blood pressure or what other exams should I undergo?
