CORTISOL. levels of this hormone are naturally higher in the morning because you make it while you sleep. cortisol does many things to your body, including raise your blood pressure! hope this helps......... PS - re:above - actually when you stand up quickly and feel dizzy, it is because your pressure is temporarily LOW. Thus your blood falls with gravity (to your legs) instead of to your head - making you dizzy. Normally your pressure then naturally adjusts and rises so you dont stay dizzy...

I am 70 years of age, and I have been diagnosed with malignant neurocardiogenic syndrome, I have obviously suffered with this most of my life as I can recall fainting spells since about 14 years of age but had never been diagnosed before, this time I was diagnosed after fainting during a tilt test and I was prescribed atenolol. I did take this for a while but found it slowed me down and when I didn t take it I experienced episodes of an sudden unstable high pulse rate. I realized that this was probably a reaction to the stopping taking the atenolol but I have continued to not take the betablocker and the sudden attacks of high pulse rate, etc., have now stopped. I haven t had a fainting episode for some time. I know I have to be careful first thing in the morning and I cannot stand still for too long, I avoid drinking alchohol and I know there are various other things which can trigger an attack which I try to avoid. When I was diagnosed I was also found to have high blood pressure at times which I was told made it more difficult to treat I know my blood pressure can suddenly go up at times, but I have bought a home monitor and I have been keeping a record and I now find that my blood pressure is fairly normal most of the time and often quite low first thing in the morning. I have also been told that I have high cholesterol. As I know there is not a cure for vasovagal syndrome and I feel that taking the beta-blockers was only masking the problem and did have some side effects I think I am better to just keep an eye on my blood pressure, take regular exercise and I have changed my diet to include garlic, herbs peppers and other foods which might help my condition. One thing that puzzles me rather is that my pulse rate is usually higher ( although not too high about 75-80 ) when I wake first thing in the morning and then drops down to about 60 when I am up and about.

i have had low blood pressuse 90/70 and lower since i had my son 6.5 years ago my pulse has been high since 2001 at least thats when it was noticed while i was in hospital. cardiologist said i have a smaller than usual heart which makes my pulse higher . said it may affect me more as i get older as it puts pressure on the arteries. however i have been tired latley . always been dizzy upon standing was told to sit down when my pulse gets high if that was the case i would have spent alot of my days sitting . playing oout side with my son i had to sit down i got dizzy and nauseated eyes couldnt adjust . it happened at christmas time while i was shopping i fell into a shelf lost vision got weak n had to sit down. blood work is great no anemia levels r all good perfect health. so why is this happening . i dont want to have a heart attack

My husband is on medications for highblood pressure and they put him on dioxidine for depression also. In december he had a minor stroke and blood pressure remains high. since he has been home first of January he has been extremely tired and hard to wake up during day. yesterday was the first real day I forced him up to go to doctors appointments. During the appointments he was hard to what seemed like waking him up and to hold conversations. Morning he was fine and than about 1 fell asleep I woke him around 4 to get him to appointment. It was hard to get him up and spent most of his time with eyes were closed and seemed like it was difficult for him to open eyes and respond and when he did it was difficult for him to talk and to be understood. He just says he is tired and that he is a little confused. We got home and he went straight to bed and when he woke up this morning he was himself and was talking about the good day he had yesterday yes our morning was pleasant and he was awake and talking but I responded good? He said he a nice morning with me before since I am usually am at work and decided to stay home. I said what about the afternoon and he responded I know I fell asleep. I said what about at the doctors office and he said we didn t go to the office and that he didn t remember. I reflected on the events and he said I vaguely remember but I thought that was a dream because I remember teaching little kids and they were young like 6 years old and I felt like I was the same height and was confused by that. Could there be such a thing as sleepwalking and having no recollection of events from medicine becuase trying to get him to come around and answer questions was alot like trying to wake him from a sound sleep and never really woke up.

Dear colleaggues, I'm Ingrid Hilman, MD, 58 years. had my stenting on 17 Feb, 3 stents in LAD and RCA.

Since 2 weeks ago, I develop severe headaches, esp during the iningt or when I wake up in the morning and also palpitation (heart rate > 90). I feel weak during palpitation. I do not have hypertension (my BP is between 90-110 and 70-80). I do not have obesity, smoking habits, my lab is pretty good only LDL 100.

Is this because of the herbresser that I take 3 times a day?

Other drug that I take;

- Aspirin 1 x 100 mg

- Plavix 1 x 75 mg

- Lipitor 1 x 10 mg.

Appreciate your inputs on my above complaints. Thank you very much

I am a 25 yr old female that has recently lost 70 pounds and suffers from pcos. I am off all the bp medicines I was taking, and have been on a gluten free diet since 4/21/11 b/c I am allergic to wheat. I have been getting dizzy, lightheaded, and have a fast heart rate and low blood pressure when standing or sitting up. my heart rate is usually in the 60 -70 range when resting, and it's been in the high 90 - 100 range while resting. The dizziness started Sunday 6/19/11 all of a sudden, and I have kept track of my BP and symptoms since Sunday. I get this intense pressure in my head, and the get dizzy, and my heart will race when I start to feel yucky, I have trouble breathing, when my heart rate is up this high for no apparent reason. My BP will be 93/62 and HR 101 standing, or it can be 114/65 and HR 80 a few minutes later.. but if I go from lying down to sitting, it will be elevated, then it elevates when I stand, if I lay down everything is fine.. the pressure in my head goes away, the dizzyness goes away, and the HR goes back to normal... I have a shunt in place for hydrocephalus, my first shunt was placed at the age of two weeks, and first revision was done 4/5/2010. I want to know what is causing this fluctuation in BP and the dizziness, and fast HR...thanks
