Lightheaded after Laughing...

Seeing stars when laughing is by no means AFIB and to suggest so clearly proves how uneducated you actually are. When we laugh, sneeze hard, cough deeply we are forcing air out of our body and at the same time clenching this obviously puts strain on certain body parts. The retina being one of them as well as the brain. This strain and lack of o2 can cause us to see phosphenes.

Passing out or feeling like you might after laughing or talking to long is usually just caused by irregular breathing, nothing more.

Ok, you're wrong. It's called Laughter Syncope and it's a rare disorder.

Fainting while laughing is not Atrial Fibrillation! Two completely different things altogether.

OMG this has been happening to me as well. It dosent feel right it is kind of scary. The good thing is that we are actually laughing, but I never felt so lightheaded before. You are not alone.

i laugh all the time and I laugh loud. Have my whole life. Injuries my sternum 7 months ago. Self heal nothing docs can do, or at least that is what I was told. So 6 months ago injuries my arm decided to stop all vices, everything in order to get healthy. Saw doc 2 months ago. Exam results, perfect blood work, organs behaving like a 20 year old, low blood pressure, blood sugar 90, cholesterol 158. Starting to loss weight all is good except when I laugh really, really hard. Last two months I start to laugh hard, within a second or two neck and head are completely engulfed in a numbing dizziness to the point of blacking out. I see very dark circles around my eyes until I stop laughing which by the way I have to cut short, can not complete laugh otherwise I feel I may pass out. This has occured 4 times. I see the doc March 18. Age 55 height 5'4" weight was 215, now 184 and dropping goal is 165. I quit drinking, smoking, smoking, and a few other things. need to keep this legal. Does not sound like afib. Any others ideas. Thanks

I am having the same issue but I have been thinking its because of my blood pressure medicines, maybe its the opposite. I noticed after that feeling of almist blacking out that later i feel awful with headaches and more dizziness and very hard to sleep

Have your doctor check you for anemia.

I also have sarcoidosis and a thyroid problem. This has happened to me on several ocassions and within the last couple of days. I was laughing so hard. I felt as if I were blacking out and starting to pass out. When I calmed down it went away but yes, sure makes you wonder whats going on at the time.

I had the same thing happen to me; almost blacked out when laughing at movie (funny line in "Three Amigos"...I even thought I might die). I had also been experiencing a pulse in my upper thigh region/groin, and feared I had a femoral aneurysm. Thought the two symptoms could be related. I still haven't had it checked out. The vibrational pulsations in the thigh have stopped. But tonight, less than a month from last (and only other) episode, when playing games with family. I laughed so hard I got light headed again (but not as bad as the last time). Not sure what to make of it. Haven't had blood pressure problems, but haven't checked it recently. I am 52 yr female and a bit overweight. I am also a veterinarian, but unable to diagnose myself on this one, :). As soon as I can take time out from my busy practice, I mean to get checked out. Will let you know if I find out more.

I'm 31 going on 32 now. growing up sometimes i would laugh and not be able to stop for 10-20 minutes sometimes of continuous laughter. Other times i would occasionally cry from laughing. Sometimes since High School or College or so i will get short of breath if i laugh too hard or too long. the past 3-4 years though something scary happens sometimes and not others. if i just chuckle or normal mild laugh at something i'm always fine, but if i start to actually fully laugh out loud with a good hearty laugh but not forceful/hard/belly rolling at all and definitely not the rolling on floor laughing i literally used to do when i was a kid....when i just normally laugh instead of trying to contain it/hold it back and just have a natural laugh at something....if its just a short "haha" or "hahaha" or "hahahaha" i'm still fine, but if it persists more then 20-30 seconds or more then a minute or so, i will sometimes suddenly feel moderate pressure in the back of and back-top of my head, and then if i still haven't managed to stop laughing yet, i start getting light headed, if it continues a few more seconds i start getting woozy/wobbly/on verge passing out/blacking out. Thankfully at that point my body reacts and stops the laughter or the laughter has run its course finally or the fear of what is happening jolts me to seriousness which cuts the laughter immediately and alleviates the issue. If it stops at the light-headedness or sooner i usually recover right away or very quickly. if i started to black out or get woozy/wobbly, i end up feeling for anywhere from 20 minutes to a few hours the same way i felt in high school a few times when i was down in the swimming pool a few feet or more and suddenly surfaced way too fast. it's really scary to me when it happens, because i've never actually blacked out or fainted in my life, and losing consciousness is utterly terrifying to me, and the only other times i've ever came close to blacking out was when i had a really high fever a few times growing up to where i should have been in bed not at school or up doing things, or the two times at high school i got the back of my head bashed off the cinder block wall first time for standing up for some girls that were getting bullied, 2nd time for standing up for myself when someone i had thought was a friend from 2nd grade til 7th grade suddenly in homeroom in 9th grade started bad-mouthing my mother profanely/explicitly/suggestively. The first time the nurse thought i had had a concussion but said she couldn't be sure because too much time had passed before they made me go to the nurse. Even then i didn't pass out or faint, though i was groggy and having trouble with awareness and memory for a few hours afterward. so to just be within a hair of passing out/blacking out completely from just the simple act of laughing at something i found mildly funny, and pretty much because of that having to keep myself from doing more then giggling or chuckling or light laughter at anything nowdays no matter how funny it is and constantly restrain my laughter, because even a 30 second bout of normal laughter makes me nearly collapse, is terrifying to me, especially since i have no idea what if anything is wrong, though it certainly seems like something is wrong given i was able as a child/adolescent to laugh and laugh riotuously for very long periods of time sometimes with no ill-effects ever from doing so.

thank you - useful

I noticed when I laughed, I felt dizzy like I was actually going to pass out. It seem that everything was turning dark. It was a weird feeling.

the same happens to me to im just 16

I recently passed out from laughing too hard and gave myself a concussion. I think I am starting to get scared about what might be wrong.
