Carbohydrate Metabolism

Carbohydrate Metabolism

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 the...

Diabetes: Management and Pharmacotherapy

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...

Diabetes Mellitus: Type 2 and Gestational

Diabetes Mellitus: Type 2 and Gestational

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...

Type II Diabetes II: Pathophysiology

Type II Diabetes II: Pathophysiology

PathophysiologyType 2 diabetes mellitus (T2DM ) is a chronic metabolic disorder characterized by insulin resistance and progressive pancreatic β-cell dysfunction, leading to impaired glucose homeostasis. It results from interactions among genetic predisposition, environmental factors, and metabolic stressors, such as overnutrition and a sedentary lifestyle.Insulin Resistance and Glucose DysregulationEarly T2DM involves insulin resistance in skeletal muscle, adipose tissue, and the liver.

Type I Diabetes II: Pathophysiology

Type I Diabetes II: Pathophysiology

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 uptake of...

Summary

Bariatric surgery effectively treats obesity and type 2 diabetes mellitus (T2DM). Novel procedures offer insights into T2DM pathophysiology, potentially leading to new treatments and cures.

Area of Science:

Metabolic Surgery
Endocrinology
Obesity Medicine

Background:

Bariatric surgery is a primary treatment for obesity and associated conditions.
Understanding surgical impacts on glucose metabolism is crucial.

Purpose of the Study:

Review mechanisms of caloric reduction in bariatric surgery.
Analyze clinical and metabolic outcomes, including effects on type 2 diabetes mellitus (T2DM).
Describe novel procedures and their impact on glucose homeostasis and insulin sensitivity.

Main Methods:

Literature review of bariatric surgery mechanisms and outcomes.
Analysis of novel procedures and their effects on T2DM pathophysiology.
Examination of weight loss-independent mechanisms.

Main Results:

Surgically induced weight loss impacts T2DM, with gastrointestinal bypass affecting insulin sensitivity.
A dual, potentially weight loss-independent, mechanism improves glucose homeostasis post-surgery.
Bariatric surgery demonstrates high rates of T2DM resolution.

Conclusions:

Bariatric surgery is the most effective therapy for obesity and T2DM.
Improvements in insulin resistance and beta-cell function are observed.
Novel procedures provide insights into T2DM and potential therapeutic targets.
