Why Do I Feel Faint When I Skip Breakfast
Many potential cause: The most common cause of lightheadedness is simply a lack of fuel in the brain (oxygen + glucose + triglycerides) in one form or other. I'm not sure for you which is the problem - low blood pressure (i.e. Not enough blood), low blood sugar (not enough glucose) or low brain triglycerides (the preferred fuel of the brain), but it is probably one of these. Eat breakfast, and stop worrying about it. ...Read moreSee 2 more doctor answers
Ate breakfast and then 45 minutes later, dizziness, faintness, nausea, shaking etc. Ambo came and took my blood sugar it was 3.9. Why low after food?
Low glucose: You were clearly had hypoglycemia (h) and are not diabetic on medications. The possible causes of h, in your case are, too much alcohol, severe illnesses of the liver, such as severe hepatitis, can cause hypoglycemia. Another cause is a rare tumor of the pancreas (insulinoma) may cause overproduction of insulin, resulting in hypoglycemia. See a physician for help with your problem. Good luck. ...Read more

I've been sick for a week. Went out, felt very faint/shaky. Sat down/ate something and felt better. Blood sugar? I'd had breakfast 4hrs before.
Reactive hypoglycemi: This is a sudden drop of blood sugar after a meal usually 2-4 hours. It is a very unpleasant sensation and one that is easily resolved, as you discovered, by eating something, which rapidly returns the sugar to normal. A single time when this occurs is less concerning, but if persists, see your doctor who can do tests to make sure nothing else is causing it (rarely is), and help coach to prevent. ...Read more

How many years could be cut off my life? I never feel refreshed when i wake up and i skip breakfast

Hi. I have noticed that if i skip breakfast and don't eat before 1 - 2 in the day, i feel really bad. When i then eat i feel tired, pale etc. How come?
Fasting: When you fast for a period of time, your body breaks down stored sugar called glycogen in order to fuel your body. After glycogen is depleted, the body breaks down fat to form ketone bodies to fuel the brain. While some people like the feeling of high ketones, many do not. The body also releases regulatory hormones to slow down energy expenditure -- making you feel tired. Eat breakfast. ...Read moreSee 1 more doctor answer
