Syncope is the medical term for fainting. It happens when your brain doesn't get enough blood flow and you lose consciousness. Usually a slow heart rate causes a drop in blood pressure, which reduces blood flow to the brain. In most cases, you recover within seconds or minutes. A small number of people, mostly the elderly, have episodes of fainting.
If you have slurred speech, or have trouble moving an arm or a leg after fainting, call for emergency help right away. This may be a sign of stroke.
To avoid fainting.
- Avoid fatigue, hunger, and stress. Don't skip meals.
- Drink plenty of fluids.
- Avoid changing positions quickly, especially when you get up from a sitting or lying down position.
- Sleep with the foot of your bed raised.
- Don't stand for long periods of time.
- Wear elastic stockings if needed to keep blood from pooling in your legs, which may reduce blood flow to the brain.
- Diuretics and other medicines (both prescription and non-prescription) can contribute to the problem. So check with your doctor.
- Avoid wearing anything tight around your neck.
- Turn your whole body, not just your head, when looking around.
- To prevent injuries, cover floors with thick carpeting, and avoid driving or using mechanical equipment.
- Avoid caffeine and alcohol.
If you feel like you are going to faint, lie down and raise your legs to keep blood flowing to your brain. If you can't lie down, sit down and put your head between your knees, stand with your legs crossed and thighs pressed together. This can also help keep blood from pooling in your legs.
Any serious underlying health condition should be treated. When a person faints:
- Raise the legs to help increase blood flow to the brain.
- Loosen any tight clothing.
- Apply cold water to the person's face.
- Turn the person's head to the side to prevent vomiting or choking.
A pregnant woman should lie on her left side to relieve pressure on the heart.
When an irregular heartbeat causes fainting, your doctor may prescribe medications such as beta-blockers or antiarrhythmics. Your doctor may also prescribe steroids (such as fludrocortisone) or salt tablets to help you control the amount of sodium and fluids in your body.
Surgical and Other Procedures
If fainting is caused by a heart condition, such as a slow or rapid heartbeat, you may need a pacemaker.
Complementary and Alternative Therapies
Although there are no specific treatments for fainting, a number of alternative therapies can help protect the heart and blood vessels. Fainting may be caused by a serious underlying health condition. So check with your doctor before taking any herbs or supplements. Always tell your doctor about the herbs and supplements you are using or considering using.
You may have warning signs before fainting. Hypnosis, deep breathing, relaxation techniques, and biofeedback may help you avoid fainting. These techniques may also help you control fainting related to regulation of your blood pressure.
Nutrition and Supplements
To stay healthy and avoid fainting:
- Don't skip meals. Eat a healthy diet, with plenty of fruits and vegetables, whole grains, healthy protein, and good fats.
- Avoid caffeine, alcohol, and tobacco.
- Drink plenty of fluids.
These supplements may promote heart health:
- Omega-3 fatty acids, such as fish oil -- may help reduce inflammation and improve heart health. Cold-water fish, such as salmon or halibut, are good sources. Omega-3 fatty acids may increase the risk of bleeding, especially if you also take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin.
- Coenzyme Q10 -- an antioxidant that may be good for heart health. Do not take CoQ10 if you take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin. CoQ10 can make these drugs less effective. So they might not work as well.
- Alpha-lipoic acid -- an antioxidant that may be good for heart health. People who take thyroid hormone should ask their doctors before taking alpha-lipoic acid. People who have low levels of thiamine should not take alpha-lipoic acid.
- L-arginine -- an antioxidant that may help promote good circulation. Be sure to ask your doctor before taking L-arginine because it may interfere with other treatments and may not be right for you. People who have a history of a heart attack, heart disease, low blood pressure, or circulatory issues should speak to their doctors before taking L-arginine. People who take medication for circulation, including medications for erectile dysfunction, should also take caution when taking L-arginine. It can also cause problems with blood pressure, as well as make herpes infections worse. Some people may be allergic to L-arginine.
The use of herbs is a time-honored approach to strengthening the body and treating disease. However, herbs can trigger side effects and interact with other herbs, supplements, or medications. For these reasons, take herbs with care and under the supervision of a health care provider.
- Green tea (Camelia sinensis) -- an antioxidant and anti-inflammatory that may be good for heart health. Use caffeine-free products. You may also make teas from the leaf of this herb.
- Bilberry (Vaccinium myrtillus) -- an antioxidant that helps promote good circulation. Bilberry may increase the risk of bleeding, especially if you also take blood thinners, such as warfarin (Coumadin), clopidogrel (Plavix), or aspirin. People with low blood pressure, heart disease, diabetes, or blood clots should not take bilberry without first talking to their doctors. Do not take bilberry if you are pregnant or breastfeeding.
- Ginkgo (Ginkgo biloba) -- an antioxidant that may be good for heart health. Ginkgo interacts with many medications, including blood-thinners, such as warfarin (Coumadin) and clopidogrel (Plavix). People with diabetes, fertility problems, a history of seizures, and bleeding disorders may not be able to take ginkgo. Because of the potential for many interactions, do not take ginkgo without your doctor's supervision.
Sometimes, fainting may be due to drops in a hormone called cortisol. Ask your doctor about testing for low cortisol. Some doctors may prescribe cortisol hormone supplements or use nutrients and herbs to get cortisol levels back to normal.
Before prescribing a remedy, homeopaths take into account a person's constitutional type -- your physical, emotional, and intellectual makeup. An experienced and certified homeopath will assess your individual constitution and symptoms, and then recommend remedies. Below are common remedies used for fainting or pre-fainting symptoms:
- Carbo vegetabilis -- used for fainting or lightheadedness after rising in the morning, from loss of fluids, or from becoming overheated
- Opium -- used for fainting due to excitement or fright
- Sepia -- used for fainting following prolonged standing, exercise, or fluid loss due to fever
Acupuncture may help treat fainting. A clinical analysis of 102 serious cases of loss of consciousness reported that acupuncture helped in a large number of these cases.
Acupuncture does not often cause side effects or complications. Some people may faint during acupuncture treatments, although it is not considered a serious complication.
