  • I started on the 5:2 diet in October 2016 and lost 10kg in 8 months. I am pleased with this because, when I stray a bit from the diet, I do not put much weight back on – at least not so far (touch wood)!

    What is tricky right now is that my blood pressure (BP) has come down so much that I feel dizzy quite often. After decades of taking BP tablets for high BP, my doctor has finally acted by taking me off one BP medication (Zanidip). Nevertheless, my BP is still on the low side and I still get some dizzy spells. Hopefully, my GP will take me off the other BP tablets (Micardis) soon. Then I’ll be free of BP tablets for the first time in 40 years! Thank you 5:2.

    Being an old researcher myself, I am wondering if there’s been any research done on the precise relationship between the 5:2 diet and blood pressure? Perhaps Michael or anyone else could describe this relationship? Is the 5:2 Diet risky when blood pressure is relatively low, for example? Say about 110/65.

    Not a doctor. My blood pressure has been in the region of 110/60 for years. Don’t have dizzy spells unless sleeping & jump out of bed & only last a few seconds. Lost 13kg over 5 months on 5/2 with no effect on BP. Did drop my blood sugar levels though.

    Not sure, but you might have/had had metabolic syndrome
    One of the symptoms is high BP. Intermittent fasting can help correct it. Not sure why you’re still on meds – maybe need to consult with another physician?

    Thanks for your reply, bcjmmac. I’ll discuss metabolic syndrome with my doctor soon.

    My next step is to strut around wearing a 24-hour BP monitor to see how my BP looks over a daily cycle. My doctor and I are a bit confused by the fact that I’m not just dizzy sometimes, but I have fainted & fallen down also! Can’t help wondering if some of this is psychosomatic!

    batwunder, my husband began to have low blood pressure and dizziness about 6 years ago. Fasting did not change it and the cardiologist did a lot of head-scratching and came up with no real reason for the hypotension. It turned out to be related to another condition which Fasting will not correct. Bcjm might be right about getting a 2nd opinion.
    Good luck

    Thanks for your suggestion of a second opinion, fasting_me. Could I be so bold as to ask what other condition your husband experienced that Fasting will not correct?

    batwunder, I have had very similar symptoms as you are experiencing. I lost about 12kg in 2017 and have continued with 5:2 to maintain my weight loss. I was taking BP medication prior to losing. When I was down about 9kg my BP was getting too low and I experienced dizziness as well. My doc took me off medications. After about 4 or 5 months my BP started going up again (I had reached my weight goal) so back on one med, then later an additional beta blocker as I was having some spikes. (Changed doctors around that time.)

    I had the 24 hour monitor a few weeks ago. It managed to keep me awake going on and off throughout the night and my BP averaged around 140/80 I think, which is higher that it normally is on meds.. I also have “white coat syndrome” which will send it soaring when I am anywhere near a doctor’s office. Do you ever have spikes in your BP? Do you measure it at home?

    Measuring at home, my readings are usually below 120/80 and often below 100/70, which is low for me and makes me feel lightheaded and just not very good in general. But because of the occasional spikes I still need the medications. We appear to have very similar situations.

    Thanks for your post, CalifDreamer. We certainly do seem to have similar situations, so it would be good to keep in touch.

    I haven’t received results from the 24-hour monitoring yet, but have been measuring my BP at home for many years now. Second readings each measurement day were averaging about 125/70 over the last two months, before my doc took me off one BP medication. But I have recorded lows of about 106/65 sometimes and experienced dizziness on those days and on other days as well.

    Re spikes upwards, I have seen 2 or 3 as high as 167/90, including one on a day when I fainted and fell over unexpectedly and then recorded my BP after standing up again! But I don’t see spikes very much, probably because I am still taking 1 BP medication.

    I’ll post the results of the monitoring once I get them, Cheers!
