Diabetic Neuropathy

The most common form of diabetic neuropathy is Distal Symmetrical Sensorimotor Polyneuropathy (DSPN), a length-dependent neuropathy that typically affects both feet symmetrically and gradually progresses upward. DSPN primarily involves sensory nerves initially, followed by motor nerve involvement in advanced stages. Patients commonly present with burning sensation in the feet, numbness, tingling, pricking pain, electric shock-like sensations, pins-and-needles feeling, increased sensitivity to touch, nocturnal pain, muscle cramps, weakness, heaviness of legs, imbalance while walking, and reduced sensation to vibration, temperature, or touch. In severe cases, loss of protective sensation can predispose patients to foot ulcers, infections, gait disturbances, and diabetic foot complications.

Peripheral neuropathy refers to a disorder resulting from damage or dysfunction of the peripheral nervous system, which comprises the nerves outside the brain and spinal cord. These peripheral nerves are responsible for transmitting sensory, motor, and autonomic signals between the central nervous system and various parts of the body. Damage to these nerves can interfere with normal nerve conduction and significantly affect sensation, movement, muscle function, circulation, and autonomic regulation.

There are multiple causes of peripheral neuropathy, with Diabetes Mellitus being one of the most common worldwide. Other causes include chronic alcohol consumption, nutritional deficiencies (especially Vitamin B12 deficiency), autoimmune disorders, infections, thyroid dysfunction, kidney disease, toxic exposure, certain medications, metabolic disorders, vascular insufficiency, trauma, hereditary neuropathies, and chronic inflammatory conditions.

Common sensory symptoms include burning sensation, numbness, tingling, pins-and-needles sensation, pricking pain, electric shock-like sensations, hypersensitivity, reduced sensation to touch or temperature, and loss of vibration perception. Motor nerve involvement may lead to muscle weakness, cramps, heaviness of limbs, reduced coordination, muscle wasting, gait imbalance, and difficulty walking.

Autonomic neuropathy is a serious form of nerve damage affecting the autonomic nervous system, the part of the nervous system responsible for regulating involuntary bodily functions such as heart rate, blood pressure, digestion, sweating, breathing, bladder control, bowel movements, temperature regulation, and sexual function. Damage to these autonomic nerves disrupts normal organ function and can lead to a wide range of systemic symptoms.

Cardiovascular autonomic neuropathy can present with resting tachycardia, exercise intolerance, dizziness, palpitations, and orthostatic hypotension. Gastrointestinal involvement may lead to bloating, nausea, early satiety, constipation, diarrhea, or delayed gastric emptying (gastroparesis). Genitourinary symptoms may include urinary retention, incomplete bladder emptying, recurrent urinary infections, and sexual dysfunction.

Radiculoplexus neuropathy is a complex and often painful neuropathic disorder involving inflammation and dysfunction of nerve roots, nerve plexuses, and peripheral nerves. It commonly affects the lumbosacral or cervical nerve plexus and is characterized by sudden onset of severe pain followed by progressive muscle weakness, sensory disturbances, and functional impairment. The condition is most frequently associated with Diabetes Mellitus and is often referred to as Diabetic Lumbosacral Radiculoplexus Neuropathy or diabetic amyotrophy when involving the lower limbs.

Patients commonly present with sudden severe burning, aching, stabbing, or deep radiating pain in the hip, thigh, buttock, lower back, shoulder, or arm region, often followed by progressive muscle weakness, muscle wasting, reduced reflexes, gait instability, and impaired limb function.

Mononeuropathy refers to dysfunction or damage involving a single peripheral nerve, resulting in localized sensory, motor, or autonomic symptoms in the area supplied by that nerve. Common forms include facial nerve palsy, oculomotor nerve palsy, median nerve involvement such as carpal tunnel syndrome, ulnar neuropathy, radial neuropathy, femoral neuropathy, and peroneal nerve palsy. Symptoms depend on the specific nerve involved and may develop suddenly or progressively, including sharp or burning localized pain, numbness, tingling, weakness, reduced grip strength, and altered sensation.

Unlike many conventional Ayurvedic centers, Rishi Ayurveda Hospital & Research Centre is equipped with advanced diagnostic facilities that enable objective assessment of disease severity, progression, and treatment outcomes:

• VPT (Vibration Perception Threshold): Assessment and grading of sensory neuropathy.
• PPG (Photoplethysmography): Evaluation of peripheral microcapillary circulation and vascular status.
• CAN (Cardiac Autonomic Neuropathy Testing): Assessment of autonomic nervous system involvement in diabetic patients.
• Orthostatic Hypotension Assessment: Evaluation of postural blood pressure regulation and autonomic dysfunction.
• HCP (Hot & Cold Perception Testing): Measurement of thermal sensory function and small fiber nerve involvement.
