Sudden tinnitus, blacking out, dizziness

In general, sudden tinnitus, blurred vision, and dizziness may be caused by conditions such as hypoglycemia, iron-deficiency anemia, or cervical spondylosis. Treatment options include dietary adjustments, oral medications, or surgery, depending on the cause. Specific analyses are as follows:

1. Hypoglycemia

If one frequently has a selective or unbalanced diet, intestinal absorption of glucose may be reduced, failing to meet the body's energy demands and leading to hypoglycemia. After onset, insufficient energy supply to brain tissue can trigger symptoms such as tinnitus, dizziness, and blurred vision. Consuming high-sugar foods such as candies, bread, or fruit juices can effectively alleviate these symptoms.

2. Iron-deficiency anemia

Significant blood loss or inadequate nutritional intake can lead to iron deficiency in the body, resulting in anemia. This condition impairs blood and oxygen supply to the brain, causing symptoms like tinnitus, dizziness, and blurred vision. Under medical guidance, oral iron supplements such as iron dextran oral solution or sustained-release ferrous tablets can be taken to effectively control the condition.

3. Cervical spondylosis

Prolonged desk work or frequent低头 (looking down at mobile phones) may lead to intervertebral disc protrusion, which compresses the vertebral artery and causes paroxysmal dizziness, tinnitus, hearing loss, vomiting, and other symptoms. Treatments may include surgical procedures such as laminoplasty or artificial disc replacement, performed at a hospital.

Besides the above relatively common causes, symptoms could also result from cerebral hemorrhage, cerebral infarction, myocardial infarction, or other serious conditions. It is important to undergo thorough examinations and follow appropriate treatments under medical supervision.
