Dizziness is a common symptom, and there are numerous causes for it, including abnormal brain functions, disorders of fibrous tissues and so on.
Clinically, dizziness is regarded as a precursor reaction of diseases. The common pathological types are dizziness and distension in the head, a feeling of top-heaviness, a sensation of the brain shaking inside, and vertigo with blurred vision.
Especially for people with hypertension, symptoms such as dizziness, vertigo and numbness in the limbs will appear before the onset of hypertension. However, some people have normal blood pressure but often experience inexplicable dizziness. What on earth is going on?
The cervical spine is the connection hub between our head and trunk, with many nerves and blood vessels passing through it. When problems occur in the cervical spine, such as cervical hyperosteogeny and intervertebral disc herniation, nerves and blood vessels will be compressed, resulting in symptoms like dizziness, headache, vertigo and numbness in the hands. The symptoms of cervical spondylosis usually worsen when bowing the head, raising the head or turning around.
Ear Diseases
Long-term dizziness may also be a symptom manifestation of ear diseases. Among them, Meniere's disease is the most common, which can lead to symptoms such as vertigo, dizziness and nausea. In addition, benign paroxysmal positional vertigo (BPPV) is also a frequently-occurring ear disease, mostly caused by the detachment of otoliths, and it will aggravate vertigo and dizziness when the head moves.
Diabetes
Long-term high blood glucose will cause blood vessel damage, resulting in insufficient blood supply to the brain and the appearance of dizziness symptoms. Besides, diabetes can also cause nerve damage, such as damage to balance and coordination abilities, thus leading to dizziness. The symptoms of diabetes include polydipsia (drinking a lot), polyphagia (eating a lot), polyuria (urinating a lot) and weight loss.
Brain Diseases
Brain diseases are one of the common causes of long-term dizziness. The most common one is vertebrobasilar insufficiency, which is considered to be caused by reasons such as blood vessel stenosis, poor blood flow or thrombosis formation. The symptoms of insufficient blood supply to the brain include dizziness, headache, vertigo and tinnitus, and usually worsen after physical activities.
Heart Diseases
The dizziness caused by heart diseases is rather complicated. It is usually related to the ischemia and hypoxia of the cerebrovascular system, which will lead to an increase in intracranial pressure and then trigger dizziness symptoms in patients.
Cold
Cold is often a common trigger for dizziness, especially when nasal congestion occurs after catching a cold, it is more likely to cause dizziness symptoms. People with rhinitis or sinusitis are also prone to dizziness. It is advisable to go to the hospital for examinations to determine exactly what causes the dizziness.
Although dizziness is very common in life, it should also be taken seriously. Only by clarifying the causes of dizziness can corresponding treatments be carried out. Finding the exact causes and treating them accordingly is the key.
