Fainting -Why Did You Faint? This is a question we often ask ourselves why this phenomenon occurs. We at On Call Medical Clinic would like to share the most common causes of fainting with you.
- Dehydration
Dehydration can happen if you don’t drink enough or you lose too much fluid. Then your blood pressure drops, and your nervous system can’t control it well, which could make you faint. That’s why it’s a good idea to get plenty of water, especially when it’s hot outside.
- Arrhythmia
It means your heart has an irregular beat. That sometimes slows the flow and amount of blood that gets to your brain, which can make you pass out. It may be the first or only obvious symptom of the problem. See your doctor right away if you suspect arrhythmia because it could be a sign of a serious heart problem that needs treatment.
- Cyanotic Breath-Holding
It happens mostly in kids between ages 6 months and 5 years. They cry hard enough to cut off oxygen and trigger an automatic response that makes them faint. They may turn blue, pass out for about a minute, and seem groggy afterward. They don’t do it on purpose. It’s a reflex they can’t control. Though it’s scary to see at first, it’s nothing to worry about and might even happen repeatedly.
- Low Blood Pressure
The medical term is hypoglycemia. It may make you dizzy, shaky, tired, confused, and blur your vision. You can usually fix the problem if you get a few grams of carbs from juice or candy. Otherwise, you could pass out. If that happens, you need medicine called glucagon to help your body release more sugar.
- Medicines
Some medications, like high blood pressure drugs and antidepressants, affect the way your heart and blood vessels act when you stand. This can drop your blood pressure and make you pass out. Insulin used to lower blood sugar when you have diabetes might cause hypoglycemia that also leads to fainting. In older people, different drugs sometimes combine with illness and the situation you’re in that makes you faint.
- Standing Up
f you faint when you rise, you could have a condition called postural orthostatic tachycardia syndrome (POTS). It increases your pulse too much when you stand or sit up. You might feel sick, dizzy, shaky, or sweaty, and your heart may skip a beat. And you could pass out. It can help to drink plenty of fluids, limit caffeine and alcohol, and try to get up more slowly.
- Heart Problems
Damaged heart muscle, blocked or narrowed blood vessels (coronary heart disease), and other kinds of ticker trouble can stop enough blood loaded with oxygen from getting to your brain. When it makes you pass out, it’s called cardiac syncope. It may happen without warning, sometimes repeatedly over a period of weeks. See your doctor right away if you suspect this or also have chest pain, arrhythmia, fatigue, or other symptoms.
- Shock
The technical term for this is vasovagal syncope. Your body overreacts to the sight of blood, sudden intense emotion, fear of injury, or something else that jars you. Your heart rate slows as blood vessels widen and blood pools in your legs, away from your brain. You may be cold, clammy, pale, and nauseated right before it happens. If you feel like you might faint, lie down and raise your legs.
- Coughing
Especially if it’s deep and you can’t stop, it might prevent your blood from getting enough oxygen, which could make you faint. It’s more common in babies with pertussis, but it can happen to anyone. Asthma, which makes it harder to breathe, may have the same effect. Get to a hospital right away if you have a serious asthma attack or pass out from coughing.
- Drinking Alcohol
It causes your blood vessels to expand, which can lead to a drop in your blood pressure. You can pass out when you drink so much that you reach a dangerously high blood alcohol concentration.
