Chronic senescence, driven by accumulated cellular stress and defective clearance mechanisms, is a primary driver of biological aging and age-related diseases, whereas acute senescence serves beneficial roles in development and tissue repair.
Aging is not just 'wear and tear' but involves specific cells (senescent cells) that stop dividing but secrete inflammatory factors (SASP) that damage surrounding tissue. As we age, our immune system becomes less efficient at clearing these cells, leading to accumulation and disease. Current research focuses on 'senolytics' (drugs that kill these cells) to potentially improve health in the elderly, though no universally accepted biomarker or treatment is yet standard.
Chronic senescence has detrimental effects within cells and tissues... The knowledge that senescence can cause age-related diseases has instigated researchers to develop drugs that can eliminate senescent cells. These medications could improve health in the elderly.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
