Types of Diabetic Neuropathies
Regardless of which type of diabetes you have, there is a good chance that you have developed some type of neuropathy. This condition is characterized by pain that is recurrent, and which affects your muscles and nerves. Several different types of neuropathies exist, including autonomic neuropathies, lumbar radiculoplexus neuropathies, polyradiculopathy, and pulmonary neuropathic pain.
Autonomic neuropathy
Whether you’ve recently been diagnosed with diabetes, or have been living with diabetes for a long time, you’re likely aware of the risks associated with it. One of the more serious complications of diabetes is autonomic neuropathy. This is the damage to the nerves that control your internal organs. It can affect the heart, blood pressure, sweat glands, sexual function, digestive system, and urination.
Diabetic autonomic neuropathy is a condition that can affect a number of different parts of the body. It can cause problems with the heart, blood pressure, sweat glands, digestive system, urination, sexual function, and even low blood sugar levels. The type of neuropathy you experience will depend on your individual body’s underlying condition.
There are a number of clinical and laboratory tests used to diagnose CAN. These tests are designed to detect different types of autonomic nerve damage. They can also be used to determine whether or not the condition is caused by diabetes. This information can be used to guide treatment.
Depending on the type of neuropathy, a doctor may prescribe a variety of medications to help control the symptoms. In addition, there are new treatments that may be used to slow the progression of nerve damage.
The risk of neuropathy is greater for people with type 1 diabetes. In addition, people with longer durations of diabetes are more likely to develop neuropathy. People with high blood pressure also have a higher risk. It’s important to keep your blood glucose levels within the target range to prevent further nerve damage.
People with diabetes can develop neuropathy at any time. This condition can affect many different parts of the body, including the eyes, feet, hands, and mouth. A diabetic’s healthcare team will be able to identify the areas where neuropathy may be present, and can help you decide on a course of treatment.
Symptoms can vary depending on the part of the body affected, but many people experience pain, weakness, or trouble driving at night. It may also cause a person to be unaware of low blood sugar.
Polyradiculopathy
Among the most studied of all diabetic clinical syndromes is the group of neuropathies that are caused by damage to the peripheral nervous system. These are also known as the different forms of diabetic neuropathy.
One of the most common neuropathies in patients with diabetes is small-fiber-predominant neuropathy (SFP). This disorder has a similar distribution to diabetic syphilis and distal symmetric polyneuropathy (DSP). In addition to SFP, the other diabetic neuropathies are oesophageal, cardiac, and autonomic. These disorders may present with lightheadedness, frank syncope, bradycardia, urinary retention, and difficulty swallowing solid foods.
The first step in making a diagnosis is to perform a history and physical examination. An initial examination should include reflex testing. Some tests for neuropathy include reflex amplitude, sensory testing, and motor testing. An MRI of the nerve roots may also be required for accurate diagnosis.
The first and most common etiology of neuropathy is diabetes. However, it should be noted that there are other possible causes. It is important to make a complete history and physical examination to avoid missing other possible aetiologies. Using a structured list of symptoms and signs may be useful to detect diabetic neuropathy.
In the first stage of diabetic neuropathy, there is a loss of ankle reflexes. This is followed by the development of weakness in small foot muscles. Later, in the course of the disease, patients may develop Charcot neuroarthropathy.
Another potential etiology of neuropathy in diabetes is the presence of dyslipidemia. Dyslipidaemia is associated with nerve dysfunction, digestive problems, and insulin resistance. A high body mass index is also associated with painful diabetic neuropathy. Taking measures to reduce dyslipidemia may also improve the outcome of neuropathy in diabetic patients.
Glucose control effectively halts diabetic neuropathy in patients with type 1 diabetes. In type 2 diabetes mellitus, the disease is accompanied by distal polyneuropathy. This type of neuropathy occurs in up to 50% of patients. It is usually self-limiting, though there are cases of neuropathy that result from excessive glycemic control.
A group of large clinical trials has assessed the benefits of lifestyle interventions for people with type 2 diabetes. Most of these trials include neuropathy as a secondary outcome. In the Impaired Glucose Tolerance Neuropathy (IGTN) trial, subjects with DSPN showed improved measures of CAN after participation in the intervention.
Lumbosacral radiculoplexus neuropathy
DLSRPN is a neuropathy characterized by pain, weakness, and inflammatory changes in the peripheral nerves of the lower limbs. The condition has been linked to microscopic vasculitis and inflammatory changes in cutaneous nerve biopsy tissue.
The typical symptoms of DLSRPN are pelvic-femoral pain and weakness. Patients often lose weight, and they are unable to walk unassisted. However, the disease is relatively unpredictable, presenting different symptoms in different patients. It has been suggested that the disorder can be caused by nerve ischemia, mechanical nerve root compression, or both.
Although the etiology is unclear, it is believed that patients develop the disorder because of diabetes. DLSRPN has been found in patients with type I and types II diabetes. However, there is a low incidence of the disorder in type 1 patients. A diagnosis of DLSRPN should be considered if there is a history of diabetes, lower extremity pain, and peripheral nerve abnormalities.
The pain associated with DLSRPN is often intense and persistent. The symptoms may be asymmetrical, and half of the patients develop weakness in the other leg. The lumbar region is involved in 24 percent of cases. In some patients, the long thoracic nerve is also involved. This may suggest that other causes of pain are present.
DLSRPN has also been associated with increased glycated hemoglobin levels. These higher levels may be an indication of hyperglycemia, which can increase the risk of developing neuropathy. Aside from the pain, other symptoms associated with the disorder include muscle weakness and radiculopathy. A nerve conduction study shows reduced amplitudes of compound muscle action potentials.
While DLSRPN is a relatively rare complication of diabetes, it can have significant consequences for patients. It is important to recognize the condition early and to monitor its progression. If the disease progresses, treatment should be used to alleviate symptoms and prevent further damage. This may include the use of immunomodulators to reduce inflammation and prevent the progression of the disorder. DLSRPN can also be treated with pulsed methylprednisolone, which may help alleviate pain within a few months.
The presence of neuropathy may require laboratory testing to rule out other causes of pain. Other diagnostic tests, such as bone scans and lumbar puncture, may be required to rule out neoplastic involvement.
Pulmonary neuropathic pain
Among the long-term complications of diabetes, peripheral neuropathy is one of the more common. About 60% of people with diabetes have some degree of neuropathy. It can lead to a variety of symptoms including pain, numbness, and weakness. Neuropathy can be caused by any number of conditions, including infections, physical injury, and chronic health conditions.
In patients who have been diagnosed with diabetes, the risk of peripheral neuropathy is about 12 times higher than in non-diabetics. The risk is especially high in patients over the age of 65. Patients with diabetes are also more likely to develop amputations. Fortunately, treatments are now available to help slow or reverse nerve damage.
Diabetic neuropathies are caused by neuronal inflammation or damage to the nerves. It can occur in any part of the body, including the hands, feet, legs, and heart. Treatments may include corticosteroids, plasma exchange, or immunoglobulins.
Besides being painful, neuropathy can cause problems with the digestive tract, heart, and sex organs. Neuropathy also increases the risk of infection. Symptoms of neuropathic pain usually do not respond to simple analgesics. Some anti-epileptic drugs may provide non-invasive pain relief.
Peripheral neuropathy can be diagnosed by a doctor’s examination. The doctor will check for muscle strength and sensitivity to vibration, temperature, and position changes. They may also perform nerve function tests to detect abnormal nerve conduction.
Diabetic neuropathy is most common in patients with high blood pressure and high blood fat. This can be prevented by controlling blood glucose levels and keeping blood fat levels in target ranges.
Several animal studies have shown that peripheral nerve lesions occur as a result of ischemia. This is believed to be a major determinant of peripheral neuropathy. Other factors that may increase the risk of developing peripheral neuropathy are dyslipidemia, impaired nerve blood flow, and reduced sural nerve oxygen tension.
Peripheral neuropathy is also found in people with chronic hypoxemia. Several studies have suggested that hypoxemia may be a contributing factor to the development of peripheral neuropathy. It is also believed that respiratory acidosis can contribute to the development of polyneuropathy.
