Intermediate-level nurse in charge answers: What causes dizziness due to normal blood pressure?

Introduction Many patients report that they often feel dizzy, but it is very normal to check their blood pressure. They ask what causes dizziness when blood pressure is normal, and what diseases it can or will cause. In order to help everyone better understand the symptoms of dizziness, To avoid causing unnecessary suspicion, the editor has compiled the following points, hoping to be helpful to everyone.

Dizziness is the most common clinical symptom and one of the diseases most frequently visited in outpatient and emergency departments. The causes of dizziness are varied. The level of blood pressure is only a small reason for dizziness. When a doctor saw a dizzy patient, he himself felt "dizzy". Dizziness cannot be said to be a disease. Everyone will inevitably have dizziness sometimes. Common reasons such as fatigue, lack of sleep, and high work pressure may lead to dizziness.

What kind of diseases can dizziness be a sign of?

Dizziness includes several types: dizziness, vertigo, and imbalance. These three conditions are all manifestations of dizziness.

1. Dizziness: The head is dizzy and unclear, and the head may feel bloated and tight. The above-mentioned factors such as overwork, excessive fatigue, lack of sleep, etc. can be adjusted and recovered after proper rest. Colds, hypoxia, anemia, hypoglycemia, and cervical spondylosis are also common causes.

2. Vertigo: The patient has an illusory feeling of "movement" in space and position, which is manifested as rotation of vision or a sense of self-rotation. Most patients dare not open their eyes, often accompanied by nausea, vomiting, and excessive sweating. , elevated blood pressure and other manifestations, such as Meniere's disease, benign paroxysmal positional vertigo (also known as otolithiasis), posterior circulation ischemia, cerebellar disease (stroke), etc.

3. Imbalance: Unsteady standing or unstable movement during activities, such as Parkinson's disease and ataxia.

If patients with normal blood pressure experience dizziness, it is mostly due to unsatisfactory blood pressure control. They will experience dizziness, headache, neck swelling, heart palpitations, and mood swings day and night with the seasons, especially around blood vessels. Fluctuations, vascular murmurs, and heart murmurs may all induce plaque formation, cause ischemia and hypoxia in tissues and organs, and induce dizziness. If your blood pressure is normal and you often experience dizziness, we should consider the following symptoms.

1. Transient ischemic attack is a very common disease that young people are prone to, so they always have dizziness repeatedly. On top of the dizziness, there are some reasons for nausea. Most of them are caused by insufficient blood supply to one sex. The blood pressure is normal without checking. The exercise boxes on the head are all normal. There are no obvious symptoms of ischemia. There are transient symptoms, but they cannot be detected by checking. ,

2. Migraine. Some people would say that migraine is a pain in the head. Why does dizziness occur? Because migraine is caused by vasospasm, ischemia and hypoxia. Under the symptoms of hypoxia, in addition to inducing pain, dizziness and insufficient blood supply may occur.

3. Rhinitis and sinusitis. It seems that rhinitis and sinusitis have no obvious relationship with the blood supply and ischemia of the brain, but the nasal cavity is not smooth, especially when sinusitis has symptoms of nasal congestion. Insufficient blood supply to the brain causes dizziness and headache.

4. Vertigo, which is also the most common symptom in the cerebrovascular department. Once you have experienced vertigo, you need to go to the otolaryngology department to rule out the symptoms of ear nerve hypoxia and ischemia

5. Overuse of the brain, staying up late, overwork, and poor rest are the most common symptoms nowadays. Most people recommend that mental workers who use their brains for a long time and experience symptoms of itching due to ischemia, hypoxia, and hypoxia need to pay more attention to rest and drink more water to promote blood circulation. Appropriate exercise can increase blood flow, which can also gradually improve.

6. Anemia. Some anemic patients will have an increase in oxygenated hemoglobin content, which will induce ischemia and hypoxia. In severe cases, dizziness, palpitations, and chest tightness will occur. These are also secondary diseases. , caused by insufficient blood supply to the heart. Anemia symptoms need to be corrected promptly to relieve them.

7. In a state of anxiety and depression, especially when there is lack of sleep, insomnia and dreaminess, autonomic nervous system disorders will occur, and symptoms of dizziness and ischemia and hypoxia in the brain will occur. This is a typical syndrome that requires anti-anxiety, anti-depression, and if necessary, auxiliary treatment to treat the symptoms of insomnia and dreaminess.

8. Hypotension can also occur when the blood pressure is relatively low and the brain center is insufficient, especially when the circulating blood volume is insufficient due to exposure to the sun, leading to dizziness.

9. Heatstroke. When the weather is particularly hot, especially in summer, a lot of sweating will cause circulation and insufficient blood flow to induce ischemia and hypoxia. Not only will dizziness occur, but also skin inflammation may occur. Dryness, nausea, vomiting, and rotating things are also quite dangerous.

That is to say, dizziness when blood pressure is normal is related to the above diseases. All diseases are a signal that you are not feeling well. This signal needs to be identified based on symptoms, signs and necessary auxiliary examinations. Only the cause can be treated symptomatically. Simply treating vertigo is meaningless and can easily delay the condition.
