What is Comprehensive Diabetic Neuropathy?

Diabetic neuropathy (DN) is the most common chronic complication of diabetes; it occurs in 50% of T1DM and T2DM patients. The most common form is distal symmetric polyneuropathy (DSPN) — distal sensory loss in stocking-glove distribution.

Pathogenesis: hyperglycemia → polyol pathway, advanced glycation end products (AGEs), oxidative stress, microvascular ischemia → axonal damage and demyelination. Painful DN occurs in 20-30%; significantly reduces quality of life.

Subtypes: DSPN, autonomic (cardiac, gastrointestinal, urogenital, sudomotor), mononeuropathy (median, ulnar, peroneal, cranial nerve III/IV/VI), proximal motor (diabetic amyotrophy/Bruns-Garland), thoracoabdominal radiculopathy. Treatment: glycemic control + pregabalin/duloxetine/gabapentin + foot care.

Symptoms

Distal numbness, tingling, burning

Stocking-glove distribution sensory loss

Nocturnal pain and allodynia

Loss of balance, falls

Foot ulcers, painless trauma

Autonomic: orthostatic hypotension, gastroparesis, bladder dysfunction

Risk Factors

Long diabetes duration (>10 years)

Poor glycemic control

Smoking and alcohol use

Hypertension and dyslipidemia

Tall stature, advanced age

Vitamin B12 deficiency (metformin)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

Distal numbness, burning
Painful symmetric distal pain
Foot ulcer, callus changes
Orthostatic dizziness, syncope
Erectile dysfunction, urinary symptoms
Annual neuropathy screening (10g monofilament)

Treatment Methods

HbA1c <7% (T1DM more effective; modest in T2DM)

Pregabalin 150-600 mg/day (first-line)

Duloxetine 60-120 mg/day

Gabapentin 1800-3600 mg/day

Capsaicin patch 8%, lidocaine patch

Foot care, orthotics, podiatry consultation

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
