What Causes Feeling Sick And Fainting During Dinner?

When I go out to dinner sometimes I feel really sick and I have even passed out before in the middle of resturaunts. I was wondering if this could be because I don't eat enough food throughout the day and somehow eating a meal latercan cause my blood pressure to drop? If so, is this something to worry about?

Thanks for your question on Healthcare Magic.
I can understand your concern.
Yes, not eating food entire day cant cause such symptoms of fainting down a d feeling sick.
You are not taking any food through out the day. This causes hypoglycemia. Brain needs glucose for its normal function.
So hypoglycemia will cause shut down in brain function and this will lead to fainting and sick feeling.
So better not to fast for whole day. Eat small meals or fruits during day time and take proper meal at night.
Don't worry, you will be alright by this.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
