Dr. Lv Zhiqin
Dizziness and headaches can be caused by various factors, mainly including the following aspects:
1. Dehydration: A lack of body water can affect blood circulation, reducing blood flow to the brain and causing dizziness.
2. Anemia: Insufficient quantity or quality of red blood cells reduces the blood's ability to carry oxygen, thereby affecting brain function.
3. Inner ear problems: Conditions such as Ménière's disease and vestibular neuritis can disrupt balance and cause dizziness.
4. Cardiovascular diseases: Heart diseases, arrhythmias, and similar conditions can impair blood supply to the brain.
5. Neurological diseases: Conditions such as stroke, brain tumors, and multiple sclerosis can directly affect brain function.
6. Medication side effects: Some medications may cause dizziness as a side effect.
7. Psychological factors: Mental states such as anxiety, depression, and high stress can also cause dizziness.
8. Sleep deprivation: Long-term lack of sleep can impair normal brain function, leading to dizziness.
9. Malnutrition: Deficiencies in nutrients such as vitamin B12 and iron can negatively affect brain health.
Maintaining good lifestyle habits and a positive mindset can also help prevent and alleviate symptoms of dizziness and headaches.
