Peripheral Neuropathy – Types, Symptoms, Causes, Risk Factors, and Treatment

What Is Peripheral Neuropathy?

The peripheral nervous system carries information from the brain and spinal cord to the rest of the body, and also send sensory information to the central nervous system. The nerves that make up the peripheral nervous system are called peripheral nerves. Damage to these peripheral nerves resulting in weakness, numbness, and pain, is called peripheral neuropathy. It commonly affects the nerves in hands and feet, but can also affect internal organs, mouth, and face.

Diabetes is the primary cause of this condition. Trauma, infections, genetics, metabolic problems, and toxins can all result in peripheral neuropathy. It causes stabbing, burning or tingling pain in the extremities. Medications and treating the underlying condition helps improve symptoms in most cases.

What Are the Types of Peripheral Neuropathy?

There are more than 100 different kinds of peripheral neuropathies. This condition usually affects people over 55 years of age. Depending on the type and number of nerves they affect, peripheral neuropathy can be divided into:

1) Mononeuropathy - When a single peripheral nerve is damaged, it is called mononeuropathy. Injury or trauma is the most common cause. It can also result from prolonged pressure on a nerve and repetitive motions. The common examples include:

2) Polyneuropathy - Polyneuropathy is when multiple peripheral nerves are damaged at the same time throughout the body. Most cases of peripheral neuropathy are of this type. It can result from exposure to toxins, alcohol abuse, malnutrition, and conditions like kidney disease and cancer. The common examples are:

What Are the Symptoms of Peripheral Neuropathy?

The symptoms vary depending on the type of peripheral nerve damaged. The types of nerves are:

  1. Sensory nerves - These nerves receive sensations from the skin like pain, vibration, touch, and hot or cold temperatures.

  2. Motor nerves - These nerves control the movements of the muscles.

  3. Autonomic nerves - Such nerves are in charge of functions like heart rate, digestion, and blood pressure.

Peripheral neuropathy can affect any of the above nerves and can result in the following signs and symptoms:

What Are the Causes of Peripheral Neuropathy?

The causes of peripheral neuropathy are:

- Find the positive aspects of the disorder.
- Prepare for challenging situations.
- Consult or talk with the counselor or therapist.

3.

Is Caffeine Bad for Neuropathy?

The effect of caffeine was associated with side effects such as depression or locomotor stimulation. Thus, sudden and excessive caffeine intake reduced neuropathic pain state in nerve-injured rats, but only at very high doses. You should give a second thought before going for caffeine.

4.

Does Drinking Water Help Neuropathy?

Water is a staple in all the diet, and even more comfortable for those who want to reduce nerve pain. It is critical to stay hydrated throughout the day to avoid triggering pain receptors and reduce inflammation. It is better to drink eight glasses of water each day. Drinking too much water is not a good choice for your kidneys.

5.

What Is the Best Treatment for Peripheral Neuropathy?

Aim of treatment for peripheral neuropathy is to manage the condition caused by neuropathy and also to relieve symptoms. Depending on the condition, medications or therapies are chosen to be given to the patient. Therapies include:
- Transcutaneous electrical nerve stimulation (TENS).
- Plasma exchange and intravenous immune globulin.
- Physical therapy.
- Surgery.

6.

What Are the Stages of Neuropathy?

There are five stages involved in neuropathy. They are:
- The First Stage: Intermittent pain and numbness.
- The Second Stage: More constant pain.
- The Third Stage: The height of pain.
- The Fourth Stage: The numbness starts to set in.
- The Fifth Stage: Total loss of sensation

7.

How to Diagnose Peripheral Neuropathy?

Before testing, the doctor will review full medical history and perform a neurological examination. Finally, the doctor may suggest doing the following test.
- Blood test.
- Imaging test (CT or MRI).
- Nerve function tests.
- Nerve biopsy.
- Skin biopsy.

8.

To Which Extent Does Peripheral Neuropathy Get Worse?

The most usual type of peripheral neuropathy is diabetic neuropathy. This is caused due to high sugar levels. It results in nerve fiber damage in the feet and legs. Symptoms can range from numbness or tingling in a specific body part to more severe effects, such as paralysis or burning pain.

9.

What Is the Best Medication for Peripheral Neuropathy?

Medications such as Gabapentin (Neurontin, Gralise, Pregabalin, and Horizant), developed to treat epilepsy. It may relieve nerve pain only. Side effects can include dizziness and drowsiness.

10.

How Do You Sleep With Peripheral Neuropathy?

First, start by tracking the neuropathy signs and sleeping patterns, and then make sufficient health changes to the bedtime routine and daytime habits:
- Keep a regular sleep and wake schedule.
- Develop a bedtime ritual, such as reading light material or taking a warm bath.
- Eliminate or limit caffeine 4 to 6 hours before bed and reduce consumption of daytime usage.
- Avoid smoking, especially before bedtime or in the middle of the night.
- Avoid heavy meals and alcohol before sleep.
- Turn off the smartphone, iPad, computer, and TV a few hours before bedtime.

11.

What Is the Progression of Peripheral Neuropathy?

In chronic forms, signs and symptoms will progress slowly and subtly. Few people have short periods of relief that is followed by relapse. Others reach a stage where symptoms remain the same for several months or years.

12.

Does Stress Make Peripheral Neuropathy Worse?

Based on many types of research, it is known that chronic stress may worsen neuropathic pain in affected individuals. It is noted in familial amyloid polyneuropathy patients, chronic stress adversely affects peripheral nerves, potentially worsening symptoms like numbness, burning, and tingling sensations that are felt on the skin and peripheral joints.

13.

Is Neuropathy a Disability?

Neuropathy does not come under the category of diseases are considered disabilities in mild cases. But, when the severity of the disease condition affects the usual routine, work, and movement of the patient, it is considered a disability.

14.

Can You Live a Normal Life With Peripheral Neuropathy?

The condition of peripheral neuropathy due to infections, exposure to toxins, or vitamin and hormonal deficiencies, the symptoms of the disease usually resolve themselves, and these patients easily resume their normal lives. But, in most cases, neuropathy is not curable like diabetic foot, and the priority in treatment is to manage the symptoms that worry the patient each time. This might limit the patient from leading a normal life.

15.

What Is the Prognosis for Peripheral Neuropathy?

Death due to neuropathy is usually rare. If the cause of peripheral neuropathy is determined and controlled, the complications are less severe. The prognosis depends on how early the diagnosis and treatment is started. Early diagnosis and treatment lead to a greater chance that the nerve damage can be slowed or repaired. However, recovery usually takes a very long time that might range from a period of months to even years. On poor treatment and followup, the prognosis is very low.

16.

Can You Have Neuropathy Without Diabetes?

There are several causes of peripheral neuropathy apart from diabetes mellitus. That includes chemo-induced neuropathy, hereditary disorders, infections of an inflammatory cause, auto-immune diseases, protein abnormalities, exposure to toxic chemicals leading to toxic neuropathy, poor nutrition, kidney failure, chronic alcoholism, and certain medicines.

17.

Can Nerves Regenerate From Neuropathy?

Once a person has been affected by neuropathy, a few types are capable of getting cured. Early treatment can improve outcomes. Certain nerves get slowly regenerated if the nerve cell still remains alive. Eliminating the underlying cause prevents future nerve damage. Good nutrition, proper follow up of medications routine, mild exercise, and personal hygiene practices can speed up the healing process.

18.

Can Vitamin Deficiency Cause Peripheral Neuropathy?

The vitamins for adequate nerve function and remodeling are vitamins E, B-1, B-6, B-12. Any deficiency in these vitamins may cause tingling in the hands or feet, which are symptoms of peripheral neuropathy. Thus, adequate levels of these vitamins must avoid the occurrence of peripheral neuropathy.

19.

How Does Peripheral Neuropathy Affect Walking?

Loss of balance is the most common symptom related to walking noted in cases of peripheral neuropathy. Patients are noticed to be walking with a wobbly motion. In these circumstances wearing orthopedic shoes often helps with the imbalance. Loss of coordination is particularly most specific of diabetic peripheral neuropathy. However, other symptoms that are associated with walking are muscle weakness and pain on walking.

20.

What Makes Peripheral Neuropathy Worse?

Peripheral neuropathy usually gets worsened in conditions when the disease has become chronic, progressive nerve disease. Sudden flare-ups can be caused as the result of injury or infection at the neuropathy site. The worst complication would be amputating the affected limb, which is common with uncontrolled diabetes mellitus. It is essential to control hyperglycemia and triggers of pain and infection in these patients.

21.

Can Peripheral Neuropathy Go Away?

Yes, in many people, peripheral neuropathy goes away with proper treatment. It is because the peripheral nerves have a high capability to heal independently, even though it may take months, recovery most usually occurs. However, in some cases, peripheral neuropathy may not completely go away, especially this is common in individuals with poor treatment of the underlying cause.

22.

What Helps Peripheral Neuropathy at Night?

Peripheral neuropathy usually gets worse due to the drop in the temperature at night. The discomfort and pain caused by peripheral neuropathy can be prevented by keeping up a regular sleep and wake schedule. A warm bath before sleep and limiting caffeine intake four to six hours before bedtime and trying to minimize daytime use also Helps. Smoking should be avoided, especially near bedtime, or if the person wakes up in the middle of the night. Above all, maintaining warm room temperature can eliminate the midnight flare-ups.

23.

What Is the Difference Between Neuropathy and Peripheral Neuropathy?

The peripheral nervous system is the network of nerves outside your brain and spinal cord. Thus, peripheral neuropathies usually start in the person's hands and feet. When neuropathy does not involve the peripheral nervous system, it is then known as neuropathy alone.

24.

What Are the Long Term Effects of Peripheral Neuropathy?

When peripheral neuropathy is chronic, the damage caused to those nerves can affect the nature of the particular nerves affected to send signals to muscles, joints, skin, and internal organs. This presents with long term symptoms that involve pain, numbness, loss of sensation, and other symptoms. More than the difficulties, it can also cause complications like infections. This can lead to necrosis of tissues and nerves that can never be reversed.

25.

Can Blood Pressure Medications Cause Peripheral Neuropathy?

One of the common side effects of antihypertensive drugs tends to be peripheral neuropathy. The essential drugs in that class that significantly cause peripheral neuropathy are Amiadarone and Hydralazine.

26.

What Kind of Cancer Can Cause Peripheral Neuropathy?

Tumors can cause peripheral nerve damage by invading the nerves as they grow close to and press on the nerve. It is more common in patients with cancers of the nervous system, such as brain tumors, spine tumors, and the skull base's tumors. Another non-nervous system tumor that causes peripheral neuropathy is known to be breast cancer.

27.

How to Reverse Peripheral Neuropathy?

Treating the underlying cause is vital to treat and reverse peripheral neuropathy. It varies in different people with different causes. The other ways to reverse peripheral neuropathy are by the intake of vitamin supplements (especially Vitamin B), physiotherapy, avoiding alcohol and smoking, and avoiding the triggers of the disease during the treatment process.

28.

What Treatments Are There for Peripheral Neuropathy of the Feet?

The treatment of peripheral neuropathy involves medications such as Gabapentin and Pregabalin. These medicines are primarily developed to treat epilepsy, but they are capable of relieving nerve pain. Vitamin B supplements can prevent symptoms such as tingling of the limbs. Non-steroidal anti-inflammatory drugs can be used to treat pain during flare-ups. Other than that topical treatments are used when the affected area is infected.
