Do you constantly collapsed and faint? This is terrible, but 90% of people who are suddenly faint are quite good and do not have any problem; of course, about the remaining 10%, is often happen because of a fundamental condition.

Fainting, for any kind of reason, is the result reducing blood flow to the brain for a short period. It can be caused in different parts of the body, including lowering the individual’s blood pressure, reducing heart rate and heart-related neurological reasons. We try to find out why blood pressure or heart rate drops. Some of these reasons are not alarming, but others need more evaluation.

Even if you do not get anesthetized, this decreasing of blood pressure or heart rate can be caused dizziness. Of course, it’s difficult to describe the emotional feelings that one person has during fainting, cannot be precisely dizzy or, on the other hand, she’s a light stylist, but the condition that is common in these situations is that the person feeling that the room in which it is there Round his head.
It’s difficult to figure out when we should be dizzy or lightheaded, sometimes even doctors do not know if they should be worried or not?
Here are 9 potential causes of vertigo and the cause of their occurrence. No matter what is the main cause, you should always pay attention to medical attention to new symptoms that you experience or symptoms that do not disappear.

1. Dehydration

Some people get dizzy or even choking in hot weather, when they are sweating and losing a lot of fluids. This is common when you are standing in a hot places in the summer for a while. Heat creates a way in the nervous system that reduce blood pressure.
When you feel dizzy due to water shortages, some symptoms such as dry mouth and skin, darkened urine and headache, lying down can restore the heart and brain with better blood flow and help you to feel better soon.

2. Shocked

The same reaction can occur in your body when you suddenly crash and be surprised with your friend’s voice. In this case, the body’s nervous system suddenly develops a state of tiredness and exhaustion, and blood pressure and suddenly drops, and as a result, you experience the lightness of the head. In this situation, your body may even show a sign that it’s a warning that to faint so soon. These symptoms include germination and nausea.

3. Get up quickly

Feeling light in the head and even seeing black spots also occurs when you quickly switch from one sitting position to a standstill. This is called orthostatic hypotension, which indicates a sudden drop in blood pressure when standing. This is not usually serious, but if it happens a lot or gets worse after a few minutes, instead of getting better, it’s best to consult with your doctor.

4. Abnormal heart rhythm

Compared with anesthetic symptoms caused by surprise, symptoms of anesthesia caused by abnormal heartbeat, so in this case, the person may not experience any light sensation. The irregular heartbeat, called arrhythmia, means a beating of your heart become lower or faster than the usual, which can affect the blood flow that is going to the brain.
This type of anesthetic, which is often happen without any warning signs of the heart, can be disturbing. Someone, while conversing with another person, may suddenly faint and wake up while he does not remember the feeling that had before. With this experience, often the first thing that a physician suspects is heart arrhythmia; the most common cause of sudden death due to heart problems.

5. Heart valve problems

The heart has four valves that release blood evenly throughout the body. However, some people are born with a heart valve problem, which means that their hearts should work harder than others. This congenital problem often manifests itself in its youth. While people aged 60 and over often have an arrhythmia problem. The problem with the heart valve can be a limitation of blood flow and, as a result, experience light stroke or dizziness, especially during exercise.

6. Side effects of medication

Some drugs, such as analgesic drugs and some anxiolytic drugs, can cause dizziness or lightheadedness. This is due to the fact that these drugs affect your brain directly or reduce your heart rate or lower your blood pressure.
Sometimes these symptoms are part of the common side effects of medications, and your doctor may not understand the cause of their occurrence firstly. If you are dizzy and light with these types of medications, it’s best to let your doctor take a look at your medications.

Sometimes a drug allergy, such as an allergic reaction to a narcotic drug, can be a cause of dizziness or sudden anesthetic. This allergic reaction from the immune system causes vasodilatation and therefore a decrease in blood pressure. Although this is a change in blood pressure that causes dizziness, this is actually due to an immune response.

7. Low blood glucose

If you delete one of your main meal, you’ll be seriously starving. Because the lack of adequate intake of food reduces level of glucose and, if blood levels drop too much, they will not get enough of the same brain, which is glucose, and will not get the energy they need and ultimately get confused.
Often, a small amount of food can relieve some symptoms. So, it’s good to save a little weekly snack and unbreakable chocolate in your bag or drawer for busy days.
However, if you are taking diabetes and taking a low blood sugar check, dizziness should be taken seriously, as it may be a sign of excessive blood sugar levels that can lead to seizures and anesthesia.

8. Influenza

Influenza, a virus-induced respiratory infection, can cause distressing symptoms such as fever, muscle aches, chills, sore throats, headaches and nasal congestion. But what if you feel dizzy? In this case, the hypoglycemia and hypotension of the body are the cause of the problem. You may not want to eat and drink in these conditions, but you should know that these two can reduce the possibility of vertigo and flu symptoms.

9. Stroke

If you experience dizziness (or dizziness) with muscle weakness, speech problems, anesthesia, or numbness, you may be behind all these stroke symptoms (when the blood flow to the brain is disconnected) and you should immediately contact your doctor immediately. Emergency
reducing blood flow that leads to dizziness can occur due to blood clots in the brain, which can lead to ischemic stroke.
