Cervical spondylosis: It is a clinical syndrome of a series of symptoms caused by neck injury, cervical disc degeneration, cervical vertebrae hypertrophy and hyperplasia, resulting in cervical disc prolapse, cervical vertebrae osteophytes and ligament thickening, which compress or stimulate the cervical nerves, blood vessels and spinal cord. Patients with cervical spondylosis mainly manifested as dizziness and headache, numbness of the upper limbs, neck and shoulder pain, and in severe cases, it can lead to muscle atrophy, spasm of the lower limbs, difficulty in walking, and even lead to paralysis. 2. Hyperlipidemia: lipid is the general term for lipids contained in the blood, mainly including triglycerides, phospholipids, cholesterol and free fatty acids. Increased levels of one or more types of lipids in the blood due to abnormalities in fat metabolism or operation are collectively called hyperlipidemia. Some patients have high blood lipids but have no obvious symptoms, which are often discovered during blood tests. Some patients may have symptoms such as dizziness, chest tightness, shortness of breath, insomnia, fatigue, numbness of limbs, etc. Small yellow lipomas may appear on the eyelids of some patients, and patients with hyperlipidemia are often overweight. Patients are advised to seek timely medical examination to clarify the cause of the disease and target treatment.
