Why do I feel dizzy when turning in circles?

Under normal circumstances, dizziness upon spinning may be a common phenomenon, but it could also be related to factors such as anemia, paroxysmal benign positional vertigo, hypertension, or insufficient cerebral blood supply. The specific causes are analyzed as follows:

1. Normal Phenomenon

In most cases, this is a normal physiological response. Spinning may stimulate the vestibular organs in the inner ear, affecting the body's balance function, or cause changes in blood pressure, both of which can lead to dizziness. This usually does not require excessive concern.

2. Anemia

Anemia results in inadequate blood supply to the brain, causing symptoms such as nausea and dizziness when spinning. Patients with anemia are advised to consume more foods like carrots, longan, and red dates, which may help alleviate anemic symptoms.

3. Paroxysmal Benign Positional Vertigo

Also commonly known as otolith disorder or benign paroxysmal positional vertigo (BPPV), the exact cause remains unclear, but it may be triggered by inner ear infections or surgical stimulation. It can cause symptoms such as nausea and vomiting. When spinning, the otoliths may be stimulated and move within the ear canal, resulting in dizziness even with slight rotation. Treatment may include medications such as betahistine tablets, ginkgo biloba extract tablets, or flunarizine hydrochloride tablets.

4. Hypertension

Hypertension may develop due to genetic predisposition or obesity, leading to elevated blood pressure. Common symptoms include headache and dizziness. Spinning can further increase blood pressure, triggering dizziness even with minor rotation. Medications such as furosemide tablets, spironolactone tablets, or hydrochlorothiazide tablets may be taken under medical supervision.

5. Insufficient Cerebral Blood Supply

Inadequate blood flow to the brain may cause symptoms such as tinnitus, irritability, and mood swings. Because it leads to cerebral ischemia, spinning may induce spasms in blood vessels and nerves, worsening the ischemic condition and causing dizziness even with slight movement. Treatment may involve medications such as enteric-coated aspirin tablets, clopidogrel hydrogen sulfate tablets, or atorvastatin calcium tablets, taken as directed by a physician.

Besides the above-mentioned conditions, dizziness during spinning could also result from Meniere’s disease or underdeveloped neurological function. Regardless of the underlying cause, active cooperation with medical treatment is essential.
