Neuropathy is a common chronic complication of diabetes, and nearly 60-90% of patients within 10 years of diabetes diagnosis can be found to have varying degrees of neuropathy through detailed neurological examination. For example, some diabetic patients feel numbness and tingling in their hands and feet, while others always sweat half of their body. These symptoms may seem unrelated, but an examination at the hospital may reveal a combination of neuropathy. In fact, the various symptoms of diabetic neuropathy are all caused by damage to different functional nerves. Diabetic neuropathy can be divided into sensory neuropathy, motor neuropathy and autonomic neuropathy, and the different neuropathies can exist separately or together. Peripheral sensory neuropathy is the most common neuropathy in the early stages of diabetes. Sensory nerves are responsible for transmitting various sensory signals to the brain, such as pain when you touch something sharp or hot. In addition to pain, there are also sensory abnormalities, such as ankylosis, burning sensation, or hypersensitivity to touch, any slight touch will lead to severe pain or serious discomfort, but when really subjected to external stimuli such as heat, cold or stabbing, but the sensation is dull or completely If the patient’s balance and coordination are lost, he or she may have an unstable gait and may feel like stepping on cotton underfoot. The various sensory abnormalities of sensory nerve disorders are usually symmetrically distributed, often occurring at the ends of the extremities, with symptoms in the feet and lower legs being the most common, and worsening in the quiet state or at night. Physical examination often reveals localized hyperalgesia and hyperalgesia, and some patients may have characteristic sensory abnormalities in areas adjacent to the glove and sock-covered areas at the ends of the extremities. Motor nerves convey the brain’s commands to the muscles and direct the body’s movements. The main symptoms of motor nerve injury are muscle atrophy, weakness or even paralysis during movement. Injuries to different motor nerves can manifest as different symptoms. For example, damage to the motor nerve, abducens nerve, and facial nerve may result in ptosis, diplopia, and strabismus. Autonomic nerves are the nerves that regulate the activity of the body’s internal organs. For example, heartbeat and gastrointestinal motility are not controlled by the conscious mind, but by the autonomic nerves. Diabetic autonomic neuropathy mainly affects the cardiovascular system, digestive system, genitourinary system, vascular transmission and contraction function, sweat gland function, etc. The clinical manifestations are various: for example, abnormal sweating, abdominal distension, diarrhea and constipation alternately, upright hypotension, urination disorder, impotence, infertility, etc.
