Summary
Frequent blood glucose fluctuations, known as glycemic variability (GV), independently contribute to diabetes complications. Minimizing GV is crucial for preventing cardiovascular events and managing diabetes effectively.
Area of Science:
- Endocrinology
- Metabolic Disorders
- Cardiovascular Health
Background:
- Chronic hyperglycemia is a primary risk factor for diabetes mellitus (DM) complications.
- Glucose fluctuations (glycemic variability, GV) may independently contribute to diabetes-related complications.
- Postprandial glucose spikes and hypoglycemia increase cardiovascular events in DM.
Purpose of the Study:
- To review recent evidence on glycemic variability (GV) in diabetes mellitus.
- To clarify measurement options and definitions of GV.
- To understand the relationship between GV and diabetic complications.
Main Methods:
- Review of current scientific literature on glycemic variability.
- Analysis of different methods for measuring GV.
- Evaluation of the impact of GV on vascular complications.
Main Results:
- Glycemic variability (GV) encompasses both glucose spikes and hypoglycemic events.
- Modern diabetes management strategies (GLP-1 therapy, new insulins, pumps, bariatric surgery) reduce GV.
- Defining and measuring GV remains challenging due to lack of consensus.
Conclusions:
- Minimizing GV is a therapeutic target to reduce cardiovascular events in diabetes.
- Reducing GV may safely lower mean blood glucose and impact vascular complications.
- Further research is needed to standardize GV measurement and management.

Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

01:02Glucose Homeostasis: Regulation of Blood Glucose
5.4K
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...

5.6K
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...

Individualization in dosing regimens is the customization of medication doses for individual patients. Its necessity arises from the goal of maximizing therapeutic benefits while minimizing risks. This approach is pivotal because human responses to drugs can vary widely; what is effective for one person may be inadequate or excessive for another. Interpatient (intersubject) variability refers to differences in drug responses between individuals, while intrapatient (intrasubject) variability...

8.6K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

1.3K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
