In addition to dizziness, some patients may also experience headache, chest tightness, numbness in the limbs, and weakness in the extremities. It is recommended to check blood lipids, routine blood tests, liver function and kidney function, if necessary, because sometimes the cause of dyslipidemia has to be further identified, such as whether it is caused by nephrotic syndrome or hyperlipidemia. If a patient has hyperlipidemia, he or she can also take oral lipid-lowering medication if necessary. The most commonly used lipid-lowering drugs in clinical practice are beta and statin drugs, which are widely used in clinical practice. Statin lipid-lowering drugs can help lower LDL and cholesterol, and can also raise HDL. While applying the drugs, patients are recommended to combine lifestyle interventions, such as exercise for weight loss, smoking cessation, alcohol cessation, and a low-salt, low-fat diet. If the patient still has dizziness after the improvement of the thickening, further transcranial Doppler and head CT examinations will be performed to help further clarify the cause of the dizziness.
