Peripheral Neuropathy

Overview

Peripheral Neuropathy is a condition where the nerves that carry messages to and from the brain and spinal cord to the rest of the body become damaged or diseased. In India, this is incredibly common, particularly due to the high prevalence of diabetes, affects nearly one in four people with chronic high blood sugar. Imagine your body's electrical wiring getting frayed; when these wires (nerves) are damaged, they may send 'static' in the form of pain or stop sending signals entirely, leading to numbness. This condition matters because healthy nerves are essential for balance, walking, and protecting your limbs from injury. At Sanjeevi Hospital in Sangareddy, we understand that persistent 'pins and needles' or burning sensations can significantly disrupt your sleep and quality of life. Left untreated, it can lead to foot ulcers or loss of mobility, but with early intervention and proper management, most patients can lead active, pain-free lives.

Symptoms to watch for

• Gradual onset of numbness or prickling sensations in your feet or hands.
• Sharp, jabbing, throbbing, or burning pain that may feel like an electric shock.
• Extreme sensitivity to touch, where even the weight of a bedsheet feels painful.
• Pain during activities that shouldn't cause pain, such as standing on your feet.
• Lack of coordination and frequent falling due to loss of sensation.
• Muscle weakness or feeling like your legs are heavy and tired.
• A sensation as if you are wearing invisible socks or gloves.
• Changes in sweating patterns or feeling unusually hot or cold in the limbs.
• Slow-healing sores or ulcers on the feet that you might not feel.

Causes & risk factors

• Diabetes mellitus is the most frequent cause in India, leading to high blood sugar damaging nerve fibers.
• Vitamin deficiencies, particularly B12, B1, and B6, which are common in various Indian dietary patterns.
• Physical trauma or pressure on the nerve from accidents, falls, or repetitive stress.
• Chronic alcohol consumption which can lead to nerve toxicity and nutritional gaps.
• Autoimmune diseases where the body's immune system mistakenly attacks its own nerve tissue.
• Infections such as shingles, Vitamin B12 deficiency, or certain viral conditions common in the community.
• Exposure to heavy metals or certain industrial chemicals in specific work environments.
• Kidney or liver disorders that lead to an imbalance of chemicals in the bloodstream.

Diagnosis

• A detailed neurological exam checking your reflexes, muscle strength, and ability to feel vibrations.
• Blood tests to check for vitamin levels, sugar control (HbA1c), and kidney or liver function.
• Nerve Conduction Study (NCS) to measure how quickly electrical signals move through your nerves.
• Electromyography (EMG) to record the electrical activity in your muscles and detect nerve damage.
• Skin or nerve biopsy in complex cases to look for abnormalities in small nerve endings.
• Imaging tests like MRI or CT scans to check if a disc or tumor is pressing on a nerve.
• Autonomic reflex testing to see how your nerves are controlling your blood pressure and sweating.

Treatment options

Prevention & self-care

• Monitor your blood sugar levels regularly if you are diabetic or pre-diabetic.
• Eat a balanced Indian diet rich in B-vitamins, including pulses, leafy greens, and fortified cereals.
• Inspect your feet every night for small cuts, blisters, or redness that you might not feel.
• Wear comfortable, well-fitting shoes and avoid walking barefoot, even inside the house.
• Limit alcohol consumption to protect your nervous system from toxins.
• Engage in regular low-impact exercise like walking or swimming to boost circulation.
• Quit smoking, as it narrows blood vessels and reduces oxygen delivery to the nerves.
• Manage chronic conditions like kidney disease or thyroid issues with regular check-ups.
