By Dr Zulfikar BuxAssistant Professor of Emergency MedicineFainting is known medically as Syncope and is a very common presentation that you may witness or encounter at some point in life. It affects 3% of men and 3.5% of women at some point in life.Fainting is more common as you get older and affects up to 6% of people over age 75. The condition can occur at any age and happens in people with and without other medical problems.For the rest of our discussion we will use the medical term Syncope instead of fainting.WHAT CAUSES SYNCOPE?Syncope happens when the brain temporarily doesn’t get enough blood. One of the most common reasons this happens is called “vasovagal syncope.” If you have vasovagal syncope,NBA Jerseys China, your body has a reaction in which your heart beats too slowly or your blood vessels expand (or both). This can happen for lots of different kinds of reasons.People can have vasovagal syncope if they:%Have stress from fear or pain (for example,Cheap Football Jerseys, because they are injured or have blood taken for tests)%Stand for too long or are over-tired or overheated%Have an unusual reaction to urinating,Cheap Jerseys From China, coughing, or other body functionsSometimes vasovagal syncope happens with no clear cause.People can also have syncope that is not vasovagal. This can happen due to the following problems:%The heart beats too quickly or too slowly because of problems with the heart’s electrical system or because of side effects from some medicines.%Something blocks the flow of blood in the heart. This can happen in people who have conditions called “aortic stenosis” (a valve disease) or “hypertrophic cardiomyopathy” (a heart muscle disease).%Your blood pressure drops when you stand or sit up. That can happen if you:%Do not drink enough water%Take certain medicines that cause your blood pressure to drop%Drink alcohol%Lose a lot of blood (for example, if you get hurt)%Have a medical condition that affects your blood pressureWHAT ARE THE SYMPTOMS OF SYNCOPE?The most common symptoms of syncope include:· Blacking out· Feeling lightheaded· Falling for no reason· Feeling dizzy· Feeling drowsy or groggy· Fainting, especially after eating or exercising· Feeling unsteady or weak when standing· Changes in vision, such as seeing spots or having tunnel vision· HeadachesMany times,Wholesale NFL Jerseys China, patients feel an episode of syncope coming on. They have what are called “premonitory symptoms,Cheap NFL Football Jerseys,” such as feeling lightheaded, nauseous,Wholesale Hockey Jerseys China, and heart palpitations (irregular heartbeats that feel like “fluttering” in the chest). If you have syncope, you will likely be able to keep from fainting if you sit or lie down and put your legs up if you experience these symptoms.IS SYNCOPE DANGEROUS??In many cases it is not dangerous. But it can be dangerous if you fall and hurt yourself when you faint. It can also be dangerous if you faint while driving. To be safe, check with your doctor or nurse before you start driving again after you faint.WHEN TO SEE A DOCTORAnyone who faints should see a doctor. Most cases of syncope are not serious. But people can get hurt when they faint. Plus, in some cases syncope may be caused by a serious medical condition that should be treated. Knowing what caused you to faint can help you prevent it from happening again.Tell your doctor what happened before, during, and after you fainted. If someone was with you when you fainted, that person might be able to tell you what happened.The following information is helpful:% What were you doing before you passed out?% How were you feeling before you passed out?% How long were you passed out?% How well did you recover?% Any past history of fainting?% A list of the medicines you take% Any medical conditions you might haveHOW IS SYNCOPE TREATED??That depends on what is causing your?syncope. In many cases, the main treatment is to avoid the situations that cause syncope. In less common cases, other treatment might be needed. For example, you might need a pacemaker if your heart beats too slowly and this causes syncope.A vital learning point to note is that fainting is not always normal and the older we get the more likely of it being a serious cause.作者:
