why do you feel dizzy when you stand up
People requiring prolonged bed rest should sit up each day and exercise in bed when possible. People who are lying down or sitting should rise slowly and carefully. In general, it is helpful to consume adequate fluids, limit or avoid alcohol, and exercise regularly when feasible. Regular exercise of modest intensity increases the muscle tone in blood vessel walls, which reduces pooling of blood in the legs. Sleeping with the head of the bed raised may help relieve symptoms. For some people, increasing salt intake may increase water retention and lessen symptoms. Doctors may recommend that people increase their salt intake by liberally salting food or taking sodium chloride tablets. However, increasing salt intake may not be recommended for people with heart disorders.
Basically, when you sit, your blood is all in your body and circulating in your head.
But when you stand up quickly, there is a time lapse between your blood being pushed up against gravity into your head. Your adrenal glands are responsible for secreting the chemical into your body to increase blood pressure to keep the blood in the brain. If the adrenal glands are fatigued, there is a delay and your brain momentarily lacks sufficient blood. This is a formal test in the medical world called the Ragland Blood Pressure Test where you can measure your blood pressure from laying down or sitting down to standing and there should be an increase in the amount of blood pressure when you stand up so the blood is forced up into the brain against gravity (http://www. drlwilson. com/articles/adrenal_insufficiency. htm). As a smart self-defense mechanism, the brain makes your feel dizzy if it lacks sufficient blood because it s a strong signal to sit or lay down, allowing for easier flow of blood into the brain.
Clinically, I see 3 stages of adrenal fatigue based on the Raglan Sign:PStage 1 is when you feel just dizzy. Stage 2 fatigue is when you see spots of lights or changes in your vision because now there is not enough blood flow to supportPthe part of your brain that controls vision (call the occipital lobe of your brain). If vision part of your brain doesn t have enough blood, the nerves begin to fire randomly and you experience random visual phenomena like lights, black spots, etc. Stage 3 fatigue is when you black out, which is the body s self defense mechanism to get you on the floor as quickly as possible to pool blood to your brain to make sure you don t damage your brain from lack of circulation.
There is a very scary medical word for lack of sufficient blood to the brain, it s called a stroke. It may seem odd, but from a bigger picture standpoint, your body s innate intelligence is causing you to faint in order to prevent a stroke. The most important thing you can do if you are dizzy, see lights, or faint when you stand up too quickly is to a) see if you re dehydrated, and then b) get evaluated for adrenal fatigue so that your adrenal glands are strong and resilient, not just for you to be able to get up safely, but also for your ability to handle stressors from all aspects of life. If you have any of these signs when you stand up too quickly you may have adrenal fatigue. If you want help to reverse your Padrenal fatigue, fill out this survey.
