Dizziness and fatigue with normal blood sugar may be related to anemia, cervical spondylosis, cardiovascular disease and so on, and it is recommended to consult a doctor in time. 1. Anemia: As the oxygen-carrying capacity of blood is reduced in anemia, the patient’s blood circulation and tolerance may be affected. Patients may have symptoms such as dizziness, drowsiness, weakness and pallor. 2. Cervical spondylosis: It is mostly due to long-term low head work or poor sitting posture, which causes degenerative changes in the cervical spine, resulting in bulging or herniated discs. Dizziness occurs when the sympathetic nerve or spinal cord is squeezed. 3. Atherosclerosis: Atherosclerosis occurs in arteries, resulting in narrowing of blood vessels. If the lesions are located in large blood vessels such as the brain or neck, patients may experience insufficient blood and oxygen supply to the brain, which is manifested as dizziness and fatigue. When dizziness and fatigue blood sugar is normal, it is recommended to consult a doctor in time, follow the doctor’s instructions for further examination, clarify the cause with the help of the doctor, and carry out targeted treatment or therapy.
