Question: Blackouts


 ranjitechno - Sat Oct 27, 2007 5:12 pm

I am a 21 yr old male. I have experienced blackouts thrice in the past 3 yrs. All of them took place after a good meal. I vividly remember the last two times, when I ate after more than 16 hrs in empty stomach. I didnt experience complete unconsciousness but felt my senses dimming, accompanied by a rushing in my ears, ending in a total shut down of external sound. I regained complete consciousness within 5 to 10 mins time. Is this a serious problem? Someone told me that this was related to the heart, which is why I am writing in this forum. Kindly advise me on this issue and provide me with information as to what exactly this problem is. Is there a cure for this problem?

Regards,

User avatar Hi Ranjitechno,

There are several possible causes for fainting (syncope). It can be related to the heart, blood vessels, nerves or brain. Basically, anything that decreases blood flow to the brain can induce syncope.

The relationship to eating is a little difficult to put together. I would recommend you see your doctor to have a general evaluation. Doing an EKG to look for any possible rhythm problems such as long QT syndrome is a good idea.

I suspect this is likely not a serious issue but it's best to be evaluated to make sure.

Best wishes.
