Cardiovascular, peripheral vascular circulation disorders can also lead to numbness in the hands and feet. Commonly seen in: arteriosclerosis Most commonly seen in the elderly, cerebral arteriosclerosis is accompanied by internal carotid artery sclerosis stenosis. Insufficient blood supply to the brain, functional impairment of the sensory and motor centers, numbness, weakness and temporary headache or vertigo in one upper and lower limb or half of the body. Sudden ischemic stroke, difficulty in speaking and paralysis may occur as the disease migrates and worsens. Hypertension When blood pressure rises, vasoconstriction, spasm of small blood vessels throughout the body, narrowing of the lumen, resulting in reduced blood supply to the muscles of the distal limbs, peripheral circulation disorders, and temporary lack of nutrition, can cause numbness of the limbs, especially the fingers and toes are more sensitive. Numbness can occur in only a few fingers and toes, and can be relieved after a short period of time. Diabetes When middle-aged or elderly people feel numbness and pain in their hands and feet, the condition is likely to be caused by diabetes. Numbness or pain in the hands and feet is one of the symptoms of diabetic patients. 40% of diabetic patients, in addition to numbness in the limbs, are also accompanied by a feeling of crawling and burning skin. The key to treating diabetes is to lower blood sugar, usually control the diet and keep blood sugar at normal levels. The numbness of the hands and feet will gradually reduce or disappear. Self-diagnostic points: Wandering numbness, sometimes like ants crawling (with an ant-walking sensation), is typical of cardiovascular disease. Numbness in the tips of the fingers and toes on both sides at the same time (numbness in both hands, both feet or both feet), and even more importantly, the feeling of wearing gloves or thick socks (the feeling of a layer of paste on the hands and feet), suggest the symptoms of diabetes. Numbness in one arm and leg is a sign of stroke and hemiplegia. If you have numbness in your hands and feet due to vascular disease, you should not take it lightly and go to the hospital as soon as possible to have an angiogram to further confirm the diagnosis and treatment.
