Whatever the cause of the fainting, it results from a decrease in blood flow in the brain for a short time, said the badistant professor of medicine at the Department of Cardiology of the Langone Medical Center at New York University, Lawrence Phillips: and presented 9 reasons for the possibility of dizziness and exposure In case of fainting, call to consult the doctor immediately after the suffering of any new symptom or other does not go away from her even:
Drought
Some people tend to feel dizzy or even faint when exposed to heat and sweat and lose many fluids. Extreme heat causes a pathway in the nervous system that leads to low blood pressure. When you feel dizzy with dehydration (dry mouth, skin, dark urine, and headaches), lying down keeps your heart and brain bloody, which helps you feel better faster.
The surprises
In such cases, the nervous system makes great efforts to reach exhaustion and the blood pressure drops suddenly, causing vertigo. If you lose consciousness, some signs usually seem to alert you, such as the tendency of your skin to turn green and cause nausea.
Stay up
Exposure to dizziness or even the perception of blackheads during a fast rise to a sitting position results in a decrease in perceptual blood pressure. This is usually not a big problem, but if it happens again or if the situation worsens instead of improving after a few minutes, it is advisable to consult the doctor.
Heart rhythm is abnormal
In relation to the symptoms badociated with fainting due to a sudden event, heart-related loss of consciousness occurs so quickly that no dizziness can be observed. An irregular heartbeat means that the heart beats slowly or very quickly, affecting the blood supply that reaches the brain.
This type of sudden fainting, which often occurs without warning, is the most disturbing. For example, a person may suddenly fall asleep while talking to someone and wake up to find themselves on the ground without remembering anything in advance. According to the Mayo Clinic, this type of trial encourages emergency physicians to immediately think about abnormal heart rhythms, which are among the most common causes of sudden heart death.
Heart valve problems
The heart sits on 4 valves to distribute the blood evenly throughout the body. However, some people have heart valve problems at birth, which means that their hearts have to work harder to perform their duties well. These conbad problems affect more young people, while adults 60 years of age and older are more prone to irregular heartbeats. Heart valve problems can limit blood flow and cause dizziness, especially during exercise.
Side effects of drugs
Some medicines, such as painkillers and antidepressants, can cause dizziness and fainting. This happens because these drugs directly affect the brain, slow down the heart rate or lower the blood pressure to stimulate these symptoms. There is also a small percentage of the cause of the allergic reaction to the medication taken.
Low blood sugar
Deleting a given meal can seriously affect blood sugar, which can cause vertigo when the brain is not powered, ie glucose, which it needs energy.
Most of the time, eating will treat the symptoms and you are advised to take snacks to ensure your fullness and provide you with the necessary energy on days of high pressure, such as protein panels. If you have diabetes and are taking medications that lower your blood sugar, you should not underestimate the vertigo, as this may mean that your blood glucose is seriously reduced and may lead to unconsciousness.
Influenza
This type of respiratory infection caused by the virus can cause unpleasant symptoms such as fever, muscle aches, colds, sore throats, headaches and nasal congestion. However, if you feel dizzy, it may be due to dryness and low blood sugar resulting from the loss of desire to eat or drink.
AVC
If you experience dizziness badociated with muscle weakness, difficulty speaking, numbness or numbness, the stroke may be causing these symptoms and so consult your doctor promptly.
