Sudden sweating and dizziness in middle-aged and elderly people are generally considered to be caused by hypoglycemic reaction, posterior circulation ischemia and neurosis.
1. Hypoglycemic reaction: If the patient has a history of diabetes mellitus, improper diet and improper application of drugs, it may cause hypoglycemic reaction, inducing sudden dizziness and severe sweating symptoms.
2. Posterior circulation ischemia: some old people have arteriosclerosis, which causes blood vessel narrowing. Once the symptoms of posterior circulation ischemia occurs, it will cause vasospasm, which induces insufficient blood supply to the brain, and causes strong dizziness and cold sweat, accompanied by unsteady walking and light-headedness.
3. Neurosis: Elderly people may have autonomic dysfunction, leading to dizziness, sweating and other symptoms, and psychological factors, environmental factors and genetic factors.
In addition, other factors that cause dizziness and profuse sweating cannot be ruled out. It is recommended that patients need to complete the relevant examinations and find the cause of the disease, and then be treated under the guidance of specialists.
