Carbohydrate Metabolism01:36

Carbohydrate Metabolism

10.8K
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...

Diabetes Mellitus: Type 2 and Gestational

2.2K
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: Management and Pharmacotherapy

233
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 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...

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...

Glucose Homeostasis: Regulation of Blood Glucose01:02

Glucose Homeostasis: Regulation of Blood Glucose

1.4K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...

Area of Science:

  • Metabolic disorders
  • Endocrinology
  • Obesity research

Background:

  • Type 2 diabetes mellitus (T2DM) and obesity are closely linked, but their intricate interactions require further elucidation.
  • Understanding these connections is crucial for developing effective therapeutic strategies.

Purpose of the Study:

  • To redefine T2DM as an energy surplus-induced condition.
  • To explore the adaptive mechanisms the body employs in response to energy surplus.
  • To propose a unified framework for understanding the interplay between T2DM and obesity.

Main Methods:

  • This perspective synthesizes current knowledge on T2DM and obesity.
  • It proposes a novel interpretation of T2DM pathogenesis based on energy balance.
  • It highlights the role of adenosine derivatives as key signaling molecules.

Main Results:

  • T2DM is characterized by a decline in beta cell function, aiming to prevent severe obesity via weight loss.
  • The body utilizes adipose tissue expansion, insulin resistance, and ultimately T2DM as adaptive strategies against excessive adiposity.
  • Adenosine derivatives (ATP, acetyl-CoA, NADH) are identified as primary signaling molecules in these adaptive responses.

Conclusions:

  • Insulin resistance and T2DM may function as protective mechanisms against severe obesity.
  • This perspective offers a new framework for interpreting T2DM etiology, pathogenesis, and treatment.
  • New research avenues are opened for understanding the relationship between T2DM and obesity.
