"Why Am I Feeling Dizzy? Uncovering the Underlying Causes"

Dizzy symptoms can occur alone or be a manifestation of other diseases. Dizzy feelings can be unpleasant and may affect normal life and learning. There are many reasons for dizziness, and if it persists for too long, it needs to be taken seriously. It is important to identify the cause as soon as possible by combining it with other symptoms in order to better address the problem. So, what causes the feeling of dizziness? Let's take a look.

1. Neurological disorders such as cerebral ischemia, cerebellar lesions, brain lesions, brain trauma, and certain types of epilepsy. Additionally, patients with dysfunction of the autonomic nervous system and certain neuroses may often experience dizziness.

2. Ear diseases that affect balance can also cause dizziness.

3. Internal medical conditions such as hypertension, hypotension, various cardiovascular and cerebrovascular diseases, anemia, infection, poisoning, hypoglycemia, etc.

4. Sometimes, dizziness can be a symptom of a cold.

5. Cervical spine degeneration caused by poor posture or sleeping habits can lead to the proliferation, deformation, and degeneration of the cervical vertebrae. Tightness in the neck muscles and blocked arterial blood supply to the brain can result in insufficient blood supply to the brain, which is the main cause of dizziness. Common symptoms include tightness in the neck, limited flexibility, occasional pain, numbness and coldness in the scalp and fingers, shoulder pain, a heavy sensation, and even symptoms such as nausea and palpitations.

6. Anemia should be considered if dizziness is accompanied by fatigue and paleness. Secondary anemia can occur in patients with digestive disorders, peptic ulcers, gastrointestinal bleeding, and chronic inflammatory diseases.

7. High blood viscosity due to conditions like hyperlipidemia and thrombocytosis can slow blood flow and lead to insufficient blood supply to the brain, causing symptoms such as fatigue, dizziness, and weakness. Currently, the incidence of these diseases is increasing.

8. Patients with cerebral arteriosclerosis often experience dizziness, insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Cerebral arteriosclerosis narrows the inner diameter of cerebral blood vessels, reducing blood flow and causing insufficient blood and oxygen supply to the brain, which leads to dizziness. The clinical characteristics are mainly dizziness, sleep disturbances, and memory loss, along with headache in the parietal and occipital regions, mild paralysis, speech disorders, and emotional excitability. The condition usually progresses slowly, and dizziness is often aggravated or appears during changes in body position.

9. In the early stages of heart disease and coronary heart disease, some patients may only experience symptoms such as headache, dizziness, weakness in the limbs, difficulty concentrating, tinnitus, or forgetfulness, without significant discomfort such as chest tightness, palpitations, or shortness of breath. Heart conditions such as cardiac arrest, paroxysmal tachycardia, paroxysmal atrial fibrillation, and ventricular fibrillation can lead to acute cerebral ischemia, manifesting as dizziness, blurred vision, gastric discomfort, and fainting.

10. Drug poisoning is another common cause of dizziness, with streptomycin, neomycin, kanamycin, and gentamicin being the most common offenders. In addition to dizziness, patients may also experience vertigo and sensorineural hearing loss due to cochlear nerve damage. Chronic lead poisoning often manifests as neurasthenia syndrome with symptoms such as dizziness, headache, insomnia, forgetfulness, fatigue, and excessive dreaming, as well as decreased body temperature and appetite.

11. Functional hypoglycemia can also cause symptoms such as dizziness, palpitations, and a feeling of weakness. Tremors may occur on an empty stomach or during exertion, sometimes accompanied by convulsions and loss of consciousness. During emotional stress or excessive hyperventilation, respiratory alkalosis can occur due to increased carbon dioxide excretion, leading to cerebral hypoxia, dizziness, and fatigue. Patients may also feel numbness and coldness in the face, hands, and feet, accompanied by occasional feelings of dissociation.

12. Vasodepressor syncope is often triggered by emotional stress, pain, fear, bleeding, hot weather, fatigue, hunger, insomnia, etc. Patients often experience dizziness, vertigo, nausea, upper abdominal discomfort, paleness, and cold sweats, accompanied by植物神经功能紊乱. Blood pressure may drop, and the pulse may become weak. Vasodepressor syncope is more common in physically weak young women.

Orthostatic hypotension refers to symptoms such as dizziness, blurred vision, leg weakness, vert
