What causes dizziness due to insufficient cerebral blood supply?

Generally, dizziness caused by insufficient cerebral blood supply may be due to unhealthy lifestyle habits, improper dietary habits, hypotension, cervical spondylosis, arrhythmia, and other factors. Symptomatic treatment through general therapy and medication is required. If experiencing discomfort, it is recommended to seek timely medical attention and undergo appropriate treatment under a doctor's guidance. Detailed analysis is as follows:

1. Unhealthy Lifestyle Habits

Long-term熬夜 (staying up late), irregular作息 (作息) patterns, and insufficient sleep can lead to physical fatigue, affect blood circulation, reduce blood supply to the brain, and cause dizziness, possibly accompanied by fatigue, poor concentration, and memory decline. It is recommended to maintain a regular schedule, ensure adequate sleep, and avoid staying up late or overexertion.

2. Improper Dietary Habits

Long-term high-salt, high-sugar, high-fat diets can increase blood viscosity, slow blood flow, and impair cerebral blood supply. Prolonged dieting or malnutrition may lead to anemia, worsening cerebral hypoperfusion, potentially accompanied by fatigue, pallor, and palpitations. It is recommended to adjust the diet, primarily consuming low-fat, low-salt foods, eating more vegetables, and ensuring balanced nutrition.

3. Hypotension

Genetic factors, insufficient blood volume, endocrine disorders, and other factors may cause hypotension. A drop in blood pressure or long-term hypotensive state may impair cerebral blood supply, causing dizziness, possibly accompanied by fatigue, palpitations, and chest tightness. It is recommended to follow medical advice to use medications such as midodrine tablets, flunarizine hydrochloride capsules, and propranolol hydrochloride tablets to alleviate symptoms.

4. Cervical Spondylosis

Chronic strain and degeneration of the cervical spine may lead to cervical spondylosis. Cervical lesions may compress the vertebral artery, affecting its ability to supply blood to the brain. The vertebral artery is one of the important channels for cerebral blood supply; when compressed, blood flow to the brainstem and cerebellum decreases, causing dizziness, possibly accompanied by neck stiffness, shoulder and back pain, and arm numbness. It is recommended to follow medical advice to use medications such as aceclofenac tablets, Jingfukang granules, and mecobalamin tablets to relieve symptoms.

5. Arrhythmia

Abnormal cardiac electrophysiology and cardiovascular diseases may cause arrhythmias. Arrhythmias such as atrial fibrillation can reduce cardiac pumping efficiency and cardiac output, affecting systemic circulation and reducing cerebral blood flow, resulting in dizziness, possibly accompanied by palpitations, chest tightness, and shortness of breath. It is recommended to follow medical guidance to use medications such as atropine sulfate injection, metoprolol tartrate tablets, and phenytoin sodium tablets for treatment.

It is recommended to engage in moderate daily exercise, such as walking or tai chi, which are gentle activities that can promote blood circulation and improve cerebral blood supply.
