What is the reason for dizziness and tinnitus when waking up early

Some friends will find that they feel dizzy and have tinnitus when they get up. There are many reasons for this situation, such as anemia, cerebral arteriosclerosis, cervical spondylosis, etc. may lead to such symptoms.

1. Dizziness caused by anemia

Such as iron deficiency anemia, hemolytic anemia, megaloblastic anemia, etc., the blood supply in the human body is severely insufficient, leading to brain hypoxia, thus causing dizziness. There are many diseases that cause anemia, such as indigestion, peptic ulcer, gastrointestinal bleeding and chronic inflammation of the digestive system, which can be complicated by anemia and cause symptoms such as dizziness. Cerebral thrombosis causes dizziness. It is also because after arteriosclerosis causes stenosis of the intimal lesions of the arterial lumen, the distal part can still automatically adjust to reduce vascular resistance and establish collateral circulation to maintain "normal" blood flow, temporarily preventing cerebral thrombosis from forming. However, patients may still experience dizziness or vertigo.

2. Cerebral arteriosclerosis causes dizziness

The inner diameter of the cerebral arteries becomes smaller, and the blood flow in the brain decreases, resulting in insufficient blood and oxygen supply to the brain, causing dizziness. In addition, patients often suffer from insomnia, tinnitus, emotional instability, forgetfulness, numbness in the limbs and other symptoms. Heart disease causes dizziness

Such as rheumatic heart disease, congenital heart disease, hypertensive heart disease, coronary heart disease, myocarditis, etc., atherosclerosis occurs in the coronary arteries of the heart, causing myocardial ischemia, weakened blood power, and cannot be transmitted to the brain nerve center, causing cerebral ischemia or infarction. Therefore, in the early stages of heart disease, patients will experience symptoms such as headache, dizziness, weakness in the limbs, and difficulty concentrating. Low blood pressure causing dizziness

Such as constitutional hypotension, physical hypotension, secondary hypotension, etc., the blood flow in the body is slow, causing ischemia of distal capillaries, thereby affecting the supply of oxygen and nutrients to tissue cells; the excretion of carbon dioxide and metabolic waste; especially affecting the blood supply to the brain and heart, and finally leading to a significant decline in body function and causing dizziness.
