Diabetes Mellitus: Overview and Type I Subtype01:22

Diabetes Mellitus: Overview and Type I Subtype

5.7K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes Mellitus: Type 2 and Gestational

5.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes: Symptoms, Diagnosis, and Complications

2.6K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Pathophysiology of Diabetes

4.1K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Insulin: Dosing Regimen and Adverse Effects

1.0K
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

14.8K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Area of Science:

  • Neurology
  • Endocrinology
  • Autonomic Neuroscience

Background:

  • Sudomotor dysfunction is a common, early indicator of diabetic neuropathy, affecting autonomic nervous system small fibers.
  • It is frequently underdiagnosed, despite its significant impact on patient quality of life and potential for serious complications.
  • Early detection is crucial for managing dysautonomic dysfunction and preventing later complications in diabetic patients.

Purpose of the Study:

  • To present a case of sudomotor dysfunction in a diabetic patient.
  • To highlight the variability of clinical signs, including compensatory hyperhidrosis and distal anhidrosis.
  • To underscore the importance of comprehensive autonomic nervous system evaluation in diagnosis and management.

Main Methods:

  • Case report of a diabetic patient undergoing a comprehensive autonomic nervous system evaluation.
  • Clinical observation of sudomotor dysfunction symptoms.
  • Review of diagnostic approaches for autonomic dysfunction.

Main Results:

  • The patient presented with a unique combination of compensatory hyperhidrosis and distal anhidrosis, showcasing symptom variability.
  • Autonomic testing was instrumental in the differential diagnosis of the patient's condition.
  • The findings emphasize the underrecognized nature and diverse presentation of sudomotor dysfunction.

Conclusions:

  • Sudomotor dysfunction in diabetes is clinically variable and often underdiagnosed.
  • Comprehensive autonomic testing is essential for accurate diagnosis and management.
  • Further research is needed to elucidate pathophysiological mechanisms and develop effective therapies.
