Abnormal blood pressure:

High or low blood pressure can cause dizziness.

Hypoglycemia:

Do not eat breakfast or unreasonable diet will lead to low blood sugar, dizziness, skin mucous membrane pale, dizziness, vertigo, tinnitus, fatigue, palpitation, shortness of breath and other symptoms, if not treated in time. The consequences will be very serious.

1, before the onset of vertigo: before the onset of excessive smoke-free wine, mental instability, fatigue and insomnia and other factors.

2, vertigo attack situation:

(1) Onset at night or in the morning, sudden onset or slow onset.

(2) The first onset or repeated onset.

(3) Under what circumstances, the body position changes, the neck is twisted, or a certain body position occurs.

(4) The form of vertigo is rotational or non-rotating.

(5) Whether the strength can be tolerated and whether the consciousness is clear.

(6) Dizziness when sputum or closed eyes is relieved or aggravated, whether the stun is aggravated when the sound and light are stimulated and the position is changed.

(2) ear symptoms: deafness, tinnitus, ear nausea.

(3) Eye symptoms: black eyes, double vision, blurred vision.

(4) Neck symptoms: neck or shoulder and arm pain, upper limb numbness, limited mobility.

(5) Central nervous system symptoms: headache, disturbance of consciousness, sensorimotor disorder, language or dysarthria.

Differential diagnosis

1, cerebrovascular vertigo: sudden severe vertigo, may be accompanied by nausea and vomiting, gradually reduced after 10-20 days, more with tinnitus, deafness, and clear consciousness.

2, brain tumor vertigo: early often appear mild vertigo, can be a sense of swing, instability, and rotational vertigo is rare, often unilateral tinnitus, deafness and other symptoms, with the development of lesions can appear adjacent cranial nerve damage Signs such as numbness and sensation of the side of the disease, peripheral facial paralysis and so on.

3, cervical vertigo: manifested in various forms of vertigo, with dizziness, shaking, standing instability, floating feeling and other feelings. Repeated episodes of vertigo have a significant relationship with the sudden rotation of the head, that is, more often occurs during neck movements, sometimes with dislocation vertigo when sitting or lying down. The general attack time is short, ranging from a few seconds to a few minutes, and there is also a longer duration. Neck or back occipital pain can occur in the morning. Some patients may have symptoms of cervical nerve root compression, that is, the arm is numb, weak, and the object is involuntarily falling. More than half of the patients may have tinnitus, 62-84% of patients have headaches, and many are confined to the occipital region, often with episodic jump pain.

4, eye-derived vertigo: non-motor illusion vertigo, mainly manifested as instability, increased with the use of the eye, closed eyes after the reduction. Dizziness lasts for a short period of time. When you look at the moving objects, you will get worse. After you close your eyes, you will ease or disappear. Often accompanied by blurred vision, decreased vision or double vision. Visual acuity, fundus, and eye muscle function tests are often abnormal, and the nervous system has no abnormalities.

5, cardiovascular vertigo: vertigo caused by hypertension can be clearly diagnosed by blood pressure measurement. Carotid sinus syndrome can lead to paroxysmal vertigo or syncope. Most of the causes of the disease are factors that suddenly cause compression of the carotid artery, such as sharp neck, bow, and tight collar.

6, endocrine vertigo: hypoglycemic vertigo often occurs before hunger or eating, lasting for tens of minutes to 1 hour, the symptoms are relieved or disappeared after eating, often accompanied by fatigue, blood sugar can be found in the onset of hypoglycemia. Thyroid dysfunction can also cause dizziness, clinically based on balance disorders, and related tests for thyroid function can be diagnosed.

7, vertigo caused by blood diseases: leukemia, pernicious anemia, blood hypercoagulable diseases can cause dizziness, can be diagnosed by blood system examination.

8, neurological vertigo: the patient's symptoms are characterized by diversity, dizziness and more false vertigo, often accompanied by headache, head swelling, heavy feeling, or insomnia, palpitations, tinnitus, anxiety, multiple dreams, inattention, A variety of neurosis manifestations such as memory loss, no foreign object rotation or self-rotation, shaking feeling. For women over the age of 45, attention should also be paid to the identification of menopausal syndrome.
