I fainted twice yesterday and now today I still feel off. I have never fainted before so it was a really scary experience. What are some possible reasons for fainting? Anyone? I had a headache and nausea right before it happened. And yes I am seeing my Dr. but I have to wait till Monday because he is out today.

Are you pregnant? ;) :p

Could it be high blood pressure?

Are you pregnant? ;) :p

Could it be high blood pressure?

Just what I was thinking ;)

There are a lot of causes but the biggies are (for a woman):

1 Pregnancy

2 High or low blood pressure

3 If you are a very small woman, your blood sugar may need a boost at a certain time of the day and you are not getting it--this happens most often just as you are rising in the morning, or if you stand up too quickly

4 A circulation problem

Get this checked out, do NOT wait for it to "get better".

- A hernia (can cause nausea)

- Problems with your cervical vertebra, since misalignments of spinal vertebrae may cause fainting.

- A new medication (side effect)

- Hypoglycemia (low blood sugar)

- A Seizure

- Heart issues


Hope you feel better soon. :hug:

Are you pregnant? ;) :p

Definitely not pregnant. lol

How are you feeling now? Any new updates? Have you seen your Doctor yet?

I've had a problem with fainting ever since I can remember! I usually faint if I see blood(if I cut myself or have a nose bleed), or if my blood sugar is low. Do you eat breakfast or do you skip meals?

Also, maybe you are anemic. Get the Dr. to check your iron. Good luck, keep me posted! :)

I had a flu virus a couple years back where my primary symptoms were an extreme feeling of being hot (like a hot flash) and dizziness and fainting. Thankfully, it only lasted a couple days, but it was awful!

What Is Fainting?

Fainting, also called syncope (pronounced SIN-ko-pe), is a sudden, brief loss of consciousness and posture caused by decreased blood flow to the brain. Many different conditions can cause fainting. These include heart problems such as irregular heart beat, seizures, panic or anxiety attacks, low blood sugar (hypoglycemia), and problems with how the nervous system (the body's system of nerves) regulates blood pressure. Some types of fainting seem to run in families. While fainting may indicate a particular medical condition, sometimes fainting may occur in an otherwise healthy individual. Fainting is a particular problem for the elderly, who may suffer serious injuries from falls when they faint. Most episodes of fainting are very brief; in most cases, the individual who has fainted regains complete consciousness within just a few minutes.

Fainting is a common problem, accounting for 3% of emergency room visits and 6% of hospital admissions. Fainting can happen in otherwise healthy people. A person may feel faint and lightheaded (presyncope) or lose consciousness (syncope).

What Causes It?

Fainting may have a variety of causes. A simple faint, also called a vasovagal attack or neurally-mediated syncope, is the most common type of fainting. It is most common in children and young adults. A vasovagal attack happens because blood pressure drops, reducing circulation to the brain and causing loss of consciousness. Typically an attack occurs while standing and is frequently preceded by a sensation of warmth, nausea, lightheadedness, and visual "grayout." If the syncope is prolonged, it can trigger a seizure.

You may suffer from a simple faint due to anxiety, fear, pain, intense emotional stress, hunger, or use of alcohol or drugs. Most people who suffer from simple fainting have no underlying heart or neurological (nerve or brain) problem.

Some people have a problem with the way their body regulates their blood pressure, particularly when they move too quickly from a lying or sitting position to a standing position. This condition is called postural hypotension and may be severe enough to cause fainting. This type of fainting is more common in the elderly, people who recently had a lengthy illness that kept them in bed, and people who have poor muscle tone.

The following can cause fainting, too:

* Diseases of the autonomic nervous system. Your autonomic nervous system is the part of your nervous system that controls involuntary vital functions, such as the beating of your heart, the degree to which your blood vessels are constricted, and breathing. Autonomic nervous system problems include acute or subacute dysautonomia, chronic post-ganglionic autonomic insufficiency, and chronic pre-ganglionic autonomic insufficiency. If you have one of these disorders, you are likely to have other serious symptoms, such as erectile dysfunction (inability to have or maintain an erection); loss of bladder and bowel control; loss of the normal reflexes of your pupils; and decreased sweating, tearing, and salivation.
* Conditions that interfere with the parts of the nervous system that regulate blood pressure and heart rate. These conditions include diabetes, alcoholism, malnutrition, and amyloidosis (in which waxy protein builds up in the tissues and organs). If you take certain high blood pressure medications, which act on your blood vessels, you may be more likely to suffer from fainting. If you are dehydrated, which may affect the amount of blood in your body and, thus, your blood pressure, you may be more likely to faint.
* Heart or blood vessel problems that interfere with blood flow to the brain. These may include heart block (a problem with the electrical impulses that control your heart muscle), problems with of the sinus node (a specialized area of your heart that helps it beat), heart arrhythmia (irregular heart rhythm), a blood clot in your lungs, an abnormally narrowed aortic heart valve, or certain other problems with the structure of your heart.
* Conditions that may cause unusual patterns of stimulation to particular nerves. These include micturition syncope (fainting during or after urination), glossopharyngeal neuralgia (fainting due to inflammation and pain in a particular nerve to the mouth); cough syncope (fainting after intense coughing) and stretch syncope (fainting that occurs when stretching the neck and arms).
* Hyperventilation. If you become intensely anxious or panicked and breathe too quickly, you may faint from hyperventilation (taking in too much oxygen and getting rid of too much carbon dioxide too quickly).

Thanks everyone and thanks Jasper for that huge amount of information. I am feeling much better now. :)

My mum fainted one day after she gave blood and the idiots took TOO MUCH!!

I swear,people who you think are professionals and know things turn out not to these days!
