An interesting bit of data I found about VSG

While searching for/reading the ASMBS position statement on VSG for another post, I discovered an interesting quote:

"Although SG is generally considered a restrictive procedure, the mechanisms of weight loss and improvement in co-morbidities seen after SG could also be related to neurohumoral changes related to gastric resection or expedited nutrient transport into the small bowel."

The word neurohumoral caught my eye. I googled it and immediately found a bunch of info related to cardiovascular function. Apparently this neurohumoral function has an impact on blood pressure. I wonder if this is why I have been having issues with orthostatic hypotension lately?

I have appts with my surgeon and PCP in the next few weeks and I am going to ask.

Anybody know anything about this?

It also makes me wonder if perhaps VSG somehow jacks with the kidney hormones responsible for regulating blood pressure too. 

This started happening to me about a month after surgery. I squat or bend over and then stand back up, I get light headed, my heart speeds up and I can feel my pulse in my ears.  I try doing it slowly and it still happens. I'm on blood pressure medicine and I wonder since I've lost 55lbs, has this affected my blood pressure significantly? I plan on seeing my PCP next week about it. 

This is interesting.  My BP is running in the 80/50's lately.  I've been adding salt to my coffee and food lately and pushing water as much as I can.  

Thanks,

Sounds like you're thinking too much.  Just ride the wave and enjoy the results. LOL

Very interesting connection. My blood pressure has been very low lately.

Thanks for posting this info!  I have been wondering about this myself because It seems that when I bend down or stand up to fast I get real lightheaded. Matter of fact I past out in the barber chair a few weeks ago after exercising in the gym.  My six-month follow-up is this Wednesday and I will bring this up to my PCP as well.

The podcast that Dr Alverez posts every week about 5 or 6 weeks ago has a segment about it. You are on the right track. 

When I started getting lightheaded when standing up (this started about four months after surgery) I was told to pump my legs a few times before standing.

My heart was used to pumping blood at an increased rate for a larger body.  Now that the body was smaller the pump was working more slowly and blood tended to pool in the legs.  A light pumping or cycling motion got the blood moving again and the lightheadedness went away.

This all balanced out after a few weeks and the blood pressure adjusted to about 120/80 and has stayed there for five years.
