Summary
Real-time continuous glucose monitoring (CGM) in pregnant patients with type 2 diabetes improved A1C control. CGM also reduced infant complications compared to traditional blood glucose monitoring (BGM).
Area of Science:
- Obstetrics and Gynecology
- Endocrinology
- Diabetes Management
Background:
- Preexisting type 2 diabetes in pregnancy poses risks to both mother and infant.
- Effective glycemic control is crucial for improving pregnancy outcomes.
Purpose of the Study:
- To compare the efficacy of real-time continuous glucose monitoring (CGM) versus blood glucose monitoring (BGM) in pregnant patients with type 2 diabetes on insulin.
- To assess the impact of CGM on glycemic control and infant outcomes.
Main Methods:
- Prospective evaluation of pregnant patients with type 2 diabetes using insulin.
- Comparison of outcomes between groups using CGM and BGM.
Main Results:
- Continuous glucose monitoring (CGM) use was associated with improved A1C levels.
- CGM demonstrated a reduction in infant morbidity and mortality compared to BGM.
Conclusions:
- Real-time CGM is a valuable tool for managing type 2 diabetes in pregnancy.
- Implementing CGM can lead to better maternal glycemic control and improved infant health outcomes.

4.3K
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...

3.1K
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,...

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...

01:15Diabetes: 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.

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...

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...
