ER stress and mitochondrial dysfunction in adipocytes are central mechanisms linking obesity to systemic insulin resistance and inflammation.
Understanding that cellular stress drives disease highlights the importance of reducing the load on adipocytes through weight loss and metabolic health improvements.
StrongSupportsHIGH confidence
Adipocyte endoplasmic reticulum and mitochondrial stress, and associated changes in circulating adipokines, free fatty acids, and inflammatory mediators, are central to adverse health effects of adiposity.

- Chronic energy imbalance (caloric excess) drives adipocyte hypertrophy and hyperplasia, leading to endoplasmic reticulum (ER) and mitochondrial stress, which causes systemic insulin resistance and inflammation.Strong
- Modest lifestyle modifications (diet, physical activity, weight loss, smoking cessation) have the greatest impact on reversing obesity and its metabolic consequences compared to pharmacologic interventions.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
