SA1: One example is failed glucose homeostasis in Type 2 diabetes. Insulin is released, but body cells respond poorly, so blood glucose stays elevated. Over time this damages blood vessels, including glomerular capillaries in the kidney, reducing filtration efficiency and contributing to chronic kidney disease.
SA2: Epidemiological studies are important because they reveal patterns of disease across populations, identify high-risk groups, and help public health agencies decide where prevention efforts should be targeted. For example, they can show rising diabetes prevalence in particular age groups or communities, allowing earlier education, screening and resource allocation. They also help compare risk factors such as smoking, diet and socioeconomic status. However, their conclusions must be interpreted carefully because association does not automatically prove causation and confounding variables may influence the pattern.
SA3: Prevention is often the most important long-term strategy because it acts before severe damage accumulates. Public education, screening, reduced exposure to risk factors and early intervention can lower incidence and delay complications. However, technology becomes critically important once disease is established. Dialysis, cochlear implants and corrective eye technologies can improve survival or function when prevention alone is no longer enough. The strongest evaluation is that prevention has the greatest population-level impact, but technologies remain essential for individual management of existing disease. Therefore they should be seen as complementary rather than competing priorities.
