Fainting?????

What could be the cause of fainting? I fainted the other day at school. I was feeling dizzyish and lightheaded all day, but then all of a sudden it got really bad and i fell and fainted and i can't remember much, but my friends saw and when i woke up they were there helping me get up. My heart rate was almost normal, just a little bit fast, and my blood sugar was close to normal, just a little bit low. Also, blood pressure was pretty normal. I've been anorexic, and bulimic too for a couple of years, and it's gotten worse in the past months. I do'nt know if that could be the cause, but other than that i cna't think of anything, anyone know of any reasons that could have caused this fainting? Thanks.

I used to be in treatment for it, but not anymore, can't pay.

What causes fainting?
Fainting, which is also called syncope, can be related to many different things. More than one thing may be the cause of fainting. Sometimes a specific cause for fainting can't be found.

Fainting can happen when not enough oxygen flows through your blood and into your brain. You lose consciousness, or "pass out," for a very brief time -- just a few seconds or minutes.

A sudden drop in your blood pressure can cause you to faint. Sometimes your heart rate and blood vessels can't react fast enough when your body's need for oxygen changes. This is very common among older people. It can happen when:

You stand up fast.
You work or play hard, especially if it's very hot.
You begin to breathe too fast (called hyperventilating).
You get very upset. Being upset can affect the nerves that control your blood pressure.
You're taking medicine for high blood pressure.
Coughing, urinating and stretching can also get in the way of the flow of oxygen to the brain and may be a cause of fainting. If you faint once during one of these activities, it's probably not something to worry about. But if it happens more than once, you should tell your doctor about it.

If you faint when you turn your head to the side, the bones in your neck may be pinching on one of the blood vessels that leads to your brain. If this happens to you, be sure to tell your doctor about it.

A drop in your blood sugar may also cause you to faint. This can happen if you have diabetes, but it may also happen if you don't eat for a long time.

Some prescription medicines can cause fainting. Be sure to talk to your doctor if you think your fainting may be related to a medicine you're taking. Alcohol, cocaine and marijuana can also cause fainting.

More serious causes of fainting include seizures and problems with the heart or with the blood vessels leading to the brain.

How will the cause of my fainting be found?
Your doctor will probably want to talk to you about exactly what was happening when you fainted. He or she may ask you for details about how you felt right before and right after you fainted. Your doctor will probably also want to examine you.

What should I do if I think I'm going to faint?
If you feel like you're going to faint, lie down. If you can't lie down, sit and bend forward with your head between your knees, to help get the blood flowing to your brain. Wait until you feel better before trying to stand up.

Should I see my doctor if I faint?
You probably don't need to go to your doctor if you have only fainted one time and you are in otherwise good health. Fainting is common and usually not serious. However, if you have serious health problems, especially heart-related problems, high blood pressure or diabetes, you probably should see your doctor. See your doctor if your fainting is associated with any of these features:

Irregular heart beat
Chest pain
Shortness of breath
Sudden onset (no warning signs)
Blurred vision
Confusion
Trouble talking
Fainting when you turn your head
Fainting more than once in a month

You are hypoglycemic. The reason your bloodsugar was close to normal when you got up is simple. Your liver stores glycogen and can save you when you pass out (but it takes a LONG TIME for the glycogen to build back up in the liver after it does save you). You should go see a doctor or dietician. I am diabetic and anorexic. Although I don't binge or purge anymore, I can completely understand what you experienced! It really is a bloodsugar problem. I recommend the Weight Watchers plan. It helped me rebuild my life. Whenever I start to feel like I need to diet, etc. I go back to Weight Watchers and use their plan very strictly. I get a ton of support of everyone there and it's a very positive experience. Please, go see a doctor or dietician. If you pass out again, you might not get up.

Maybe you have low blood, but most likely it is from your eating disorders, are you in treatment for the disorders? God Bless you.
