Summary
Bariatric surgery achieves type 2 diabetes remission in 50% of patients, with bypass surgery showing better outcomes than sleeve gastrectomy. Identifying risk factors is key for managing diabetes remission and relapse post-surgery.
Area of Science:
- Endocrinology
- Metabolic Surgery
- Public Health
Background:
- Type 2 diabetes remission and relapse after bariatric surgery require clarification in large populations.
- Bariatric surgery is increasingly utilized for managing type 2 diabetes.
Purpose of the Study:
- Determine T2DM remission and relapse rates post-bariatric surgery.
- Identify factors associated with T2DM remission.
- Profile patients at risk for T2DM relapse.
Main Methods:
- Population-based cohort study using French national health insurance data (SNDS and EGB).
- Inclusion criteria: adults with type 2 diabetes undergoing bariatric surgery.
- Data analyzed from 2008-2018.
Main Results:
- 50% of patients achieved diabetes remission within 2-4 months.
- Relapse rates ranged from 13-20% over 10 years.
- Bypass surgery demonstrated higher remission and lower relapse rates compared to sleeve gastrectomy.
Conclusions:
- Bariatric surgery offers a 50% remission rate for type 2 diabetes with low relapse prevalence.
- Non-modifiable (diabetes characteristics, age, lipid-lowering therapy) and modifiable (surgery type) factors influence outcomes.
- Identifying these factors is crucial for optimizing patient management.

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...

01:22Diabetes Mellitus: Type 2 and Gestational
4.1K
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...

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...

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...

01:16Insulin: Dosing Regimen and Adverse Effects
532
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...

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.
