Summary
Metabolic surgery rapidly reverses diabetes through gut hormones like peptide tyrosine tyrosine (PYY). PYY shows promise for new diabetes treatments, independent of weight loss.
Area of Science:
- Endocrinology
- Metabolic Surgery
- Diabetes Research
Background:
- Metabolic surgery effectively reverses type 2 diabetes in humans.
- Weight-independent mechanisms drive these metabolic improvements.
- Gut hormones, including GLP-1 and PYY, are implicated in post-surgical recovery.
Purpose of the Study:
- To review the role of peptide tyrosine tyrosine (PYY) in the metabolic benefits of bariatric surgery.
- To highlight PYY's contribution to improved pancreatic islet function and survival.
- To advocate for PYY-based therapeutic strategies for diabetes treatment.
Main Methods:
- Literature review of current knowledge on PYY and metabolic surgery.
- Analysis of evidence linking PYY to appetite regulation and islet function.
- Synthesis of recent advancements in PYY research for diabetes.
Main Results:
- Peptide tyrosine tyrosine (PYY) significantly contributes to the metabolic improvements following bariatric surgery.
- PYY influences appetite regulation and enhances pancreatic islet secretory properties.
- Evidence supports PYY's role in islet cell survival and function.
Conclusions:
- PYY is a key mediator of diabetes remission after metabolic surgery.
- PYY's multifaceted effects on metabolism and islet function are crucial.
- Novel therapies targeting PYY offer a promising avenue for diabetes treatment.

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.

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...

4.2K
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...

01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
535
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...
