Diabetic Neuropathy01:22

Diabetic Neuropathy

98
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...

Diabetic Nephropathy

49
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration...

Diabetic Foot Ulcer

41
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory...

Type I Diabetes III: Clinical Manifestations

31
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the...

Type I Diabetes II: Pathophysiology01:26

Type I Diabetes II: Pathophysiology

121
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular...

Diabetic Ketoacidosis ll: Pathophysiology01:22

Diabetic Ketoacidosis ll: Pathophysiology

41
Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...

Area of Science:

  • Neurology
  • Diabetology
  • Internal Medicine

Background:

  • Diabetic polyneuropathy is a common complication of diabetes mellitus.
  • Early diagnosis and management are crucial for preventing severe neurological deficits.
  • This case highlights a complex presentation of diabetic neuropathy.

Observation:

  • A 42-year-old diabetic presented with generalized body ache, burning lower limb sensation, weight loss, nausea, vomiting, and altered bowel habits.
  • Physical examination revealed symmetrical limb wasting, proximal muscle weakness, absent ankle jerks, and decreased reflexes.
  • Nerve conduction velocity (NCV) confirmed symmetrical distal axonal and demyelinating sensorimotor polyneuropathy.

Findings:

  • Hematological and gastrointestinal malignancies were excluded as causes of the symptoms.
  • The patient's neurological symptoms significantly improved with antidepressant therapy.
  • This suggests a potential role for antidepressants in managing certain types of diabetic polyneuropathy.

Implications:

  • Antidepressants may offer a therapeutic option for managing refractory symptoms of diabetic sensorimotor polyneuropathy.
  • Further research is warranted to explore the mechanisms and efficacy of antidepressants in diabetic neuropathy.
  • This case underscores the importance of a comprehensive diagnostic approach in patients with diabetes and unexplained neurological symptoms.
