A common cause of fainting is a sudden reduction of blood flow to the brain which results from a temporary drop in blood pressure and pulse rate. These lead to a brief loss of consciousness. A fainting victim may pass out for several seconds or up to ½ hour.

There are many reasons why women faint. Medical reasons include:

• Low blood sugar (hypoglycemia) which is common in early pregnancy.
• Anemia.
• Any condition in which there is a rapid loss of blood. This can be from internal bleeding such as with a peptic ulcer, a tubal pregnancy or a ruptured cyst.
• Heart and circulatory problems such as abnormal heart rhythm, heart attack or stroke.
• Eating disorders such as anorexia, bulimia.
• Toxic shock syndrome.

Other things that can lead to feeling faint or fainting include:

• Any procedure that stretches the cervix such as having an IUD inserted, especially in women who have never been pregnant.
• Extreme pain.
• A sudden change in body position like standing up too quickly (postural hypotension).
• Sudden emotional stress or fright.
• Taking some prescription drugs. Examples are: Some that lower high blood pressure, tranquilizers, antidepressants, or even some over-the-counter drugs such as antihistamines, when taken in excessive amounts.
• Know, also, that the risk for fainting increases if you are in hot, humid weather, are in a stuffy room or have consumed excessive amounts of alcohol.

Here are some dos and don’ts to remember if someone faints:

Dos:

• Catch the person before he or she falls.
• Place the person in a horizontal position with the head below the level of the heart and the legs raised to promote blood flow to the brain. If a potential fainting victim can lie down right away, he or she may not lose consciousness.
• Turn the victim’s head to the side so the tongue doesn’t fall back into the throat.
• Loosen any tight clothing.
• Apply moist towels to the person’s face and neck.
• Keep the victim warm, especially if the surroundings are chilly.

Don’ts:

• Don’t slap or shake anyone who’s just fainted.
• Don’t try to give the person anything to eat or drink, not even water, until they are fully conscious.
• Don’t allow the person who’s fainted to get up until the sense of physical weakness passes and then be watchful for a few minutes to be sure he or she doesn’t faint again.

Do these things when you feel faint:

• Lie down and elevate both legs.
• Sit down, bend forward and put your head between your knees.

  If you faint easily:

• Get up slowly from bed or from a sitting position.
• Follow your doctor’s advice to treat any medical condition which may lead to fainting. Take medicines as prescribed but let your doctor know about any side effects, so he/she can monitor your condition.
• Don’t wear tight-fitting clothing around your neck.
• Avoid turning your head suddenly.
• Stay out of stuffy rooms and hot, humid places. If you can’t, use a fan.
• Avoid activities that can put your life in danger if you have frequent fainting spells, such as driving a motor vehicle and climbing to high places.
• Drink alcoholic beverages in moderation.

  When pregnant:

• Get out of bed slowly.
• Keep crackers at your bedside and eat a few before getting out of bed. Try other foods such as dry toast, graham crackers, bananas, etc.
• Eat small, frequent meals instead of a few large. Have a good food source of protein, such as lean meat, low-fat cheese, milk, etc., with each meal. Avoid sweets. Don’t skip meals or go for a long time without eating.
• Don’t sit for long periods of time.
• Keep your legs elevated when you sit.
• When you stand, as in a line, don’t stand still. Move your legs to pump blood up to your heart.
• Take vitamin and mineral supplements as your doctor prescribes.
• Never lay on your back during the 3rd trimester. It is best to lay on your left side. If you can’t, lay on your right side
