Effects laughing has on vega nerve

[KimF]

In the past 1 1/2 years, when I laugh suddenly, I get weak all over and feel dizzy.  If I'm standing when it happens, I have to hold on to something so I don't fall.  My family doctor told me it probably has something to do with the vega nerve but he doesn't seem to think anything can be done about the problem.
History:
I am post-menopausal (haven't had a period since age 40).  I am now 46.  I am not taking HRT. I am overweight at this time, but not morbidly obese.  My weight has fluctuated greatly since my 20's.   I am taking thyroid medication for hypothyroidism -for the last 2 years.  I have sleep apnea and use a forced air breathing apparatus at night which helps with that.  I had 2 children via c-section in 1988 and 1990.  Overall I feel pretty healthy - my muscles are strong - but generally I'm tired and don't have much energy.  I have a tendency to sprain my lower back about once a year which puts me in bed for a couple of days. If it's bad enough to where I cannot stand upright, I go to a chiropractor.

I don't know if any of this information has any bearing on my problem but thought it might be helpful to tell you.

Is there anything that can be done?  Thanking you in advance for any advice you have for me.

Best regards,
KimF

That'd be the Vagus nerve and a very important one at that. Your doctor thinks anything can be done, is he a Neurologist? If not, I might seek council with a Neurologist regarding your situation.

My sister had the problems that you described and she went to a cardiologist who told her it may be caused by pressure on the vegas nerve from the stomach being up to high...so he physically put his fingers just below her left rib cage and pulled the stomach down...Then  he showed her husband  how to do it for her and that has been several month ago....and her tiredness went away with the other synptons.
There is something that can be done...do not give up hope.

I'm 51 of age and in pretty good health. I have had scary situations occur when I laugh (hard - good joke) and faint. I've been told by my Dr that I stimulate my vagus nerve through laughing and "poof" - lights out for about 10 seconds. Pretty darn scary event. Hasn't been a problem (sitting on couch - but pretty embarring for folks around me) but I'm not looking forward to this occurring while driving the car or something else pretty important.

Any input on this and how to "fix" would be great.
