When left hand numbness occurs, under the premise of excluding physiological factors, it may be a sign of certain diseases, generally common in cervical spondylosis, transient cerebral ischemia, peripheral neuritis, diabetic peripheral neuropathy and chronic alcoholism five, specific analysis is as follows: 1, cervical spondylosis: unilateral upper limb numbness is often considered to be caused by nerve compression in cervical spondylosis, because cervical spondylosis mainly invades the cervical spine and the surrounding adjacent bones When the neck is compressed, it will cause the nerve root conduction to weaken, thus causing hand numbness; 2, transient cerebral ischemia: cerebral ischemia may exist when the patient has cerebral atherosclerosis, when the cerebral blood vessels are in a relatively narrow state, when there is insufficient blood supply to the brain, it may trigger the phenomenon of hand numbness; 3, peripheral neuritis: when suffering from peripheral neuritis, there will be peripheral When peripheral neuritis is present, there will be poor blood circulation, which will lead to limited motor activity and sensory impairment, numbness in the hands and feet, etc.; 4, diabetic peripheral neuropathy: it is a common chronic complication of diabetes, patients will have a series of signs and symptoms related to peripheral nerve dysfunction, the most common is numbness and pain in the hands and feet, insect crawling, electric shock-like sensation; 5, chronic alcoholism: alcohol has an inhibitory effect on nerves, chronic alcoholism patients’ neuronal cell membranes are thus damaged, affecting the central nervous system, which in turn leads to the occurrence of symptoms such as numbness in the hands and extremities. In addition to the above, numbness in the left hand of women may also be a sign of carpal tunnel syndrome, cerebral infarction and other diseases, it is recommended that patients go to the hospital to confirm the cause of the symptoms.
