No or little sweating in the lower body is a sign of abnormal sweating in diabetic autonomic neuropathy. There is a manifestation of yin deficiency, which causes heat in your body. As well as the effects caused by vegetative nerve dysfunction. There are no better measures for this disease, the main thing is to prevent related diseases. If you have a background of hereditary syndromes, preventive measures include the implementation of genetic counseling, carrier gene testing and prenatal diagnosis and selective abortion to prevent the birth of affected children. Relax, pay attention to personal hygiene, bathe and change clothes frequently. So, what are the preventive methods for diabetic autonomic neuropathy causing no or little sweating in the lower half of the body? The following is a brief introduction: 1, the real pathogenesis of diabetic neuropathy has not been fully elucidated, and is now believed to be mainly associated with diabetes-induced metabolic disorders such as sugar, fat, phospholipids and other metabolic disorders and peripheral nerves due to peripheral nerves and other trophic blood vessels such as arteriosclerosis, epicardial hypertrophy, vitellogenic degeneration, or even occlusion and other vascular disorders. The result is segmental demyelination of nerve fibers, axonal swelling and degeneration, fibrosis, and motor endplate tumors. The lesions are mainly seen in the peripheral nerves, spinal cord root, but also in the excitation of the medulla oblongata and muscle, therefore, the diagnosis and treatment of diabetic neuropathy focus on early diagnosis and early treatment, which can reduce the incidence and development of diabetic neuropathy. 2, “early” attention: with the continuous improvement of people’s living standards, the incidence of diabetes mellitus is rapidly rising. Diabetic peripheral neuropathy is one of the chronic complications of diabetes mellitus, with the prolongation of time, more than 90% of diabetic patients were diagnosed with diabetic peripheral neuropathy, and many of them were disabled or even lost their lives due to the deterioration of their condition. Therefore, diabetic patients, especially in the early stages of diabetes, must strengthen the understanding, because even after good control of blood glucose, there is still a large proportion of diabetic peripheral neuropathy occurs, so you can not just control blood glucose will be all right, but also actively take effective measures to prevent or slow down the occurrence of diabetic peripheral neuropathy. If early attention, prevention is better than cure, the diabetic peripheral neuropathy control in the early stage of diabetes, so that its prognosis is good, can make diabetic patients still enjoy the same high quality of life as normal people. 3, “early” discovery: diabetic peripheral neuropathy often occurs in the early stage of diabetes, insidious onset, slow progression, clinical performance varies greatly, the nerve small fiber lesions at the beginning of asymptomatic or mild symptoms, and even the use of electromyography can not be detected anomalies. With the development of the disease, patients manifest symptoms including: numbness of the limbs, symmetrical pain in the lower limbs, burning pain, pins and needles pain, sensory abnormalities, hot and cold sensations, sensory sensitization, and all the symptoms have a tendency to aggravate at night. Signs include decreased pain, temperature, and vibration sensation, wasting atrophy of small muscles, hyperhidrosis, and dilated dorsalis pedis veins. In general, only when the symptoms and signs of diabetic peripheral neuropathy appear, patients can seek medical treatment on their own, but this is often the best time to miss the treatment of diabetic peripheral neuropathy, which increases the time and difficulty of the patient’s recovery. Early diagnosis of diabetic peripheral neuropathy can lead to timely and effective medical intervention, which may slow down or stop the progression of the disease or even reverse it. Early detection of diabetic peripheral neuropathy is an important prerequisite for the treatment of good prognosis, including quantitative sensory function measurement, skin biopsy and inter-epidermal nerve endings densitometry, corneal confocal microscopy and other new technologies. 4, “early” treatment: for the diagnosis of diabetic peripheral neuropathy patients, the first must be strict and smooth control of blood glucose, because blood glucose metabolism disorders will accelerate the deterioration of diabetic peripheral neuropathy. However, the application of glucose control drugs can not completely eliminate the occurrence and development of complications, so in conjunction with dietary therapy, exercise therapy and blood glucose regulation based on treatment, the earlier the targeted drug intervention therapy, the more conducive to the improvement of diabetic peripheral neuropathy and rehabilitation. Some experts even suggest that as long as the diagnosis of diabetes, regardless of whether there are no symptoms, should actively choose drugs for treatment to prevent the emergence of peripheral neuropathy.
