If the patient’s body sways back and forth while sitting, acute cerebrovascular problems are considered to be the cause, and problems with the patient’s balance are considered to be the cause. If the problem occurs suddenly, with hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, smoking, drinking and other bad habits, the sudden appearance of this problem, consider the cerebellum or brainstem problems caused by the problem, we must consult the hospital in a timely manner. Because the cerebellum is the organ that maintains the balance of a person’s body, it can adjust muscle tone, and the patient’s body tends to be stable when sitting. If the cerebellum has problems, it will be manifested as unsteady walking, ataxia, body swaying back and forth or swaying from side to side, and it is necessary to consult the hospital to do magnetic resonance brain function imaging to clarify and carry out symptomatic treatment.
