Suddenly there is a bout of vertigo, a few seconds is fine, have you ever wondered what is causing it, is it a signal from the body, or is there something wrong with a system?
1. A sudden burst of dizziness will be fine in a few seconds, and you should be vigilant against 3 major diseases!
A sudden bout of vertigo, like a brief feeling of weightlessness, can be a situation experienced by many people. However, medical perspectives have revealed that this transient vertigo may be associated with a number of underlying health problems, particularly cervical spine disease, ischemic hypoxia, and hypoglycemia.
1. Cervical spine disease
As a key part of the body that connects the head to the body, the cervical spine plays a vital role in maintaining normal physiological functions. It not only supports the weight of the skull, but also provides a bridge to protect the spinal cord and nerve roots. The intervertebral disc and foramina between the cervical vertebrae are the channels through which nerve roots pass, and if there is an abnormality in the cervical spine, such as a herniated disc or a narrowing of the foraminum, the nerve root may be pinched, causing interference in nerve signaling.
Abnormalities in the cervical spine may also compress blood vessels. The cervical spine is surrounded by a rich network of blood vessels, including the carotid and vertebral arteries, which are responsible for supplying the brain with abundant blood. When there is a problem with the cervical spine, it can cause these blood vessels to become compressed, affecting the normal flow of blood. In this case, the brain may experience poor blood flow for a short period of time, resulting in a lack of blood supply, which in turn can trigger a feeling of vertigo.
2. Ischemic hypoxia
When the blood supply to the brain is insufficient or the oxygen supply is insufficient, it may cause brain function to be impaired, manifested as symptoms such as dizziness and dizziness. This is because the build-up and hardening of the blood vessel walls can lead to narrowing of the blood vessels, which reduces the passage of blood through and affects the blood supply to the brain.
The heart is the center of pumping blood, and any problem that affects the normal function of the heart can lead to poor blood pumping, which in turn can lead to insufficient blood supply to the brain. For example, problems such as heart valve disease, arrhythmias, myocardial infarction, etc., can negatively affect blood circulation and increase the risk of hypoxia.
Especially for middle-aged and elderly people, due to aging and the accumulation of long-term chronic diseases, the vascular system and heart function may gradually degenerate and be damaged. The presence of chronic diseases such as arteriosclerosis and hypertension may exacerbate the risk of vascular lesions, making them more susceptible to symptoms of ischemic hypoxia.
3, hypoglycemia
Glucose is the brain's main source of energy and is used to support the normal activity of neurons. When blood sugar levels drop, the brain is underpowered and neurons function is affected, triggering a range of symptoms, including vertigo.
It is important to note that people with diabetes are more likely to develop hypoglycemia. Diabetes mellitus is a chronic metabolic disease characterized by instability of blood glucose. For people with diabetes, if they do not eat in time with medication or insulin injections, or if the dose is too large, it can cause a sharp drop in blood sugar, triggering a hypoglycemic reaction.
In the case of not eating in time after a meal, insulin is still working, transferring blood sugar into the cells, and at this time the body does not get enough external glucose supply, which causes blood sugar levels to drop. For patients who inject insulin, setting the insulin dose too high can cause the same problem.
2. When vertigo occurs, how to save yourself at the first time?
1. Find a safe support point
When you are dizzy, your body's sense of balance can be severely affected, and finding a place that provides stable support, such as a chair, table, or wall, can help prevent falls and injuries.
2. Close your eyes
Vertigo is often accompanied by discomfort of the eyeball, and closing the eyes can reduce the irritation of the visual system and help restore the sense of balance. At the same time, closing the eyes also reduces external stimuli, allowing the brain to process the body's balance information more intensively.
3. Drink water
Vertigo is sometimes associated with dehydration or low blood sugar, but drinking the right amount of water can quickly restore the body's water and electrolyte balance and help relieve vertigo symptoms.
Dehydration can lead to a decrease in blood volume and an increase in blood viscosity, which can affect how well the heart pumps. In this condition, the blood supply to the brain may be reduced, leading to a feeling of vertigo. Drinking a moderate amount of water can help quickly replenish the water lost in the body, increase blood volume, and improve blood mobility, thereby relieving symptoms of vertigo.
Hypoglycemia is also a common cause of vertigo. When blood sugar levels drop, the brain's energy supply is affected, which can trigger symptoms such as dizziness and fatigue. Drinking a moderate amount of water can help promote the function of the gastrointestinal tract and help maintain normal blood sugar levels.
4. Take a deep breath
Normal superficial breathing can lead to underutilization of the lungs, while deep breathing allows more air to enter the lungs, increasing oxygen absorption and carbon dioxide excretion. This helps to increase the concentration of oxygen in the blood, facilitating the delivery of oxygen to all parts of the body, including the brain, thereby improving the oxygen supply to the brain.
Deep breathing also helps to relax the body and reduce tension and anxiety. Nervousness and anxiety are one of the common concomitant factors of vertigo symptoms, and deep breathing is considered an effective self-control technique. Deep breathing stimulates the vagus nerve and reduces the activity of the sympathetic nerves, thus helping the body to enter a state of relaxation. This state of relaxation helps to slow down the heart rate and lower blood pressure, which in turn helps to reduce tension and anxiety in the body.
The technique of deep breathing usually involves inhaling deeply, inflating the abdomen, and then exhaling slowly and completely. This process of deep breathing is usually repeated several times and can be done at any time, anywhere. By practicing the technique of deep breathing, individuals can better cope with potential triggers of vertigo and self-relieve symptoms when they occur.
These simple self-help measures may help stabilize your body and reduce vertigo symptoms at critical moments, but never lie on your back!
3. Why can't I lie on my back when vertigo occurs?
Why should you not lie on your back when vertigo occurs, because lying on your back may exacerbate discomfort in the inner ear.
The inner ear is an important organ for maintaining the body's homeostasis, mainly including the semicircular canal and canalith organs. It is responsible for sensing the posture and movement of the head and transmitting information about balance and spatial orientation to the brain through nerve signals. When we lie on our backs, the fluid in our inner ear may be more likely to overreact to head movements. This is because the semicircular canals of the inner ear contain cells that sense gravity and acceleration, and fluids may be relatively more sensitive when lying supine.
This excessive inner ear response can cause the brain to receive balance messages that are inconsistent with other sensory systems, which in turn can cause vertigo.
Lying on your back can also cause the canalith to move within the canalith organ, which is a key component of perceiving head posture. Excessive canalith movement can cause confusion in the inner ear signals, making it difficult for the brain to accurately interpret the body's position and movement status, which in turn can cause vertigo.
The visual system is closely connected to the balance system, which receives information from the external environment through the eyes to help the body maintain balance. When lying on the back, the visual system is less effective, which can cause the body's balance system to become more dependent on the inner ear and other sensory organs, causing or exacerbating vertigo.
The supine position may have an impact on the blood supply to the brain, especially for vertigo patients who already have some degree of circulatory problems. This is because the head is located at the highest point of the body, and the blood needs to overcome gravity to travel from the heart to the head when lying on your back.
For those who already have circulatory problems, this can lead to a relative reduction in blood supply to the head, increasing the risk of hypoxia to the brain.
For people with vertigo who already have some degree of circulatory problems, this change in position may make the fluctuations in blood pressure more significant, which can worsen the feeling of dizziness.
Lying on your back may also affect the normal function of your stomach. In this position, the stomach is positioned relatively high, and food and stomach acid are more likely to reflux into the esophagus, increasing the risk of nausea and vomiting. For people with vertigo, this reflux of stomach contents can cause stomach discomfort that triggers or worsens feelings of nausea.
summary
Short-term vertigo is a temporary reaction of the body, and we may not be overly concerned, but it also makes us pay more attention to the subtle changes in the body. Perhaps, this is a gentle reminder from life to make us cherish our health more and be sensitive to every signal from our body.
