Low blood pressure, dizzy after Bypass Surgery: Suggestions?

Hi @airforce1 and welcome to Mayo Clinic Connect. Low blood pressure and sudden heart rate drops can definitely cause the symptoms you are having.
I would like to connect you with @hollywoodal and @lacy2, who's husband had a triple bypass.
Can you tell us a little more about your situation? How long have you had HCM and have you discussed these current symptoms with your doctor?

...for myself at 77 i have never had a dr or nurse take my blood pressure while sitting then standing, or sitting then standing, why dont they?? J.

Father is 85 yrs old, and overweight, mainly belly fat. Has a life long history of hypertension high blood pressure. Post op triple bypass 6 weeks out and having major issues when standing or walking with walker. Feeling faint, light headed, woozy, weak, feels like about to pass out when upright blood pressure drops below one hundred over 60. Seated 137 over 82. Sitting no issues, no pain, no symptoms. Only when standing. Wearing compression socks sun rise to sun set. Sleeping in recliner, can’t tolerate sleeping in bed. Urinating and bowels working well. Medications blood thinner, cholesterol, midedrin bp elevator, eating renal diet some salt, some coffee, smart sense no butter, salmon, carrots, salad graham crackers, vanilla wafers, blueberries, cherries, watermelon. Apples, peaches. Unable to keep blood pressure up tried many things, only thing that works is staying seated which is not practical any help appreciated

I have had cardiac bypass twice, a 3 and a 5. On the second, I went down a couple times, but fortunately, I had immediate assistance. Anyway, I am not sure why it happened, but I started walking more, and I still walk as much as I can, with Gelsolin and LGMDr23 and DCM. The walking motion of the legs and hips help pump the blood back up to the heart and brain, I believe. Las Vegas Sunrise was very helpful about pushing me to walk soon after surgery. oldkarl

@oldkarl Yes walking diffinately Helps Congrats on all your bypasses we have a fellow here I have told he needs to walk more after just one bypass .My triple is 26 yrs old I thank God each day for one more .I believe being active has been what has kept me going all these years

@lioness ... Thanks for the support. We had company yesterday, and one of them tried to tell me that things like walking were not suspected of being helpful until modern med schools invented it. I had a good laugh. oldkarl

I'm a 80 yr old woman, who had by pass surgery 7mo ago, I have never taken high pressure medicine all these years, but after surgery, they gave it to me a very low dose 25mg 2x a day. The b/p kept going down to less then 100/60, so the doctor dropped me down to taking 12.5me 2x a day. It seams like after I eat and take my medication the b/p drops down and I get so weak and tired I have to sleep, I don't get dizzy. I tried only taking the b/p medicine in the morning only, and I feel much better, and don't have to take a nap. Can someone explain or show me where to find more information. Thank you for any help.

Nine years ago, I had an Aortic aneurysm and a quadruple by-pass. surgery. For six and one-half years the cardiologists kept overdosing me with beta blockers. Even though I gave them pages of documentation on what was happening they refused to listen to anything I had to say. They gave me two low flow TIAs and could not understand what was happening. After the second one I changed hospitals and doctors. My fourth cardiologist read the data I gave him and immediately took me off the beta blockers. I have been off all medication for two years and have recover some of the damage the beta blockers have down. I exercise regularly, still get periods of lightheadedness. When that happens, I take salt. If it wasn't for the internet, I would be dead.

Hi @tob, I'm not a medical doctor, but I'm wondering why you are on those medications if you BP is so low, as @hollywoodal suggests below. Can you get a second opinion?

Both my husband and I have naturally low blood pressure with no weakness, dizziness, etc. Our doctor suggested we increase our salt intake to raise it a bit naturally as @hollywoodal also suggests below.

Good luck!
