Study Notes
Type 2 Diabetes Risk Factor
- Obesity is the major risk factor for type 2 diabetes.
- About 80-90% of people with type 2 diabetes are obese (at least 20% above recommended weight).
- Obesity directly causes type 2 diabetes in these individuals.
- This chapter focuses on factors linked to excess body fat and type 2 diabetes.
Mechanisms of Obesity-Induced Diabetes
- Excess abdominal fat releases biological products (resistin, leptin, TNF-alpha, free fatty acids).
- These products reduce insulin effectiveness,
- hinder glucose usage by muscles,
- increase glucose production by the liver,
- and impair insulin release from the pancreas.
- Increased fat cells also decrease secretion of substances that enhance insulin action.
- Adiponectin, a novel protein made by fat cells, is one such compound.
- Adiponectin improves insulin sensitivity and has anti-inflammatory effects.

-
What is the role of adiponectin in relation to type 2 diabetes? a) It decreases insulin production. b) It promotes inflammation. c) It enhances insulin sensitivity and has an anti-inflammatory effect. d) It is not related to diabetes.
