Ddescribe the pathophysiology for your selected disease or illness, propose historical explanations for variations in findings (when applicable), and demonstrate use of nursing conceptual models to frame your discussion of adaptation and stressors collectively for system analysis.

properly use insulin. The pathophysiology of diabetes is complex and involves multiple physiological processes.

In type 1 diabetes, which accounts for about 5-10% of cases, the body’s immune system attacks and destroys the insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin. As a result, glucose cannot enter the cells for energy, leading to hyperglycemia. In type 2 diabetes, which accounts for about 90-95% of cases, the body becomes resistant to the effects of insulin, or the pancreas cannot produce enough insulin to meet the body’s needs.

The chronic hyperglycemia in diabetes leads to a variety of complications, including damage to blood vessels, nerves, and organs. This damage can lead to a range of health problems, such as heart disease, stroke, kidney disease, nerve damage, and vision loss.

Historically, variations in findings in the understanding and treatment of diabetes can be attributed to the limited knowledge and technology available at different points in time. For example, prior to the discovery of insulin in 1921, the only treatment for diabetes was a strict low-carbohydrate diet, which was often ineffective and led to malnutrition. After insulin was discovered, diabetes became a more manageable disease, but complications and mortality rates remained high due to the lack of monitoring tools and effective treatments for the long-term complications of diabetes. However, with advances in technology and medical research, new medications, monitoring devices, and interventions have been developed to improve diabetes management and reduce the risk of complications.

The adaptation and stressors of living with diabetes can be understood using nursing conceptual models such as the Roy Adaptation Model or the Neuman Systems Model. According to the Roy Adaptation Model, individuals adapt to stressors through four adaptive modes: physiological, self-concept, role function, and interdependence. Diabetes can create stressors in all four of these modes, such as managing blood glucose levels, coping with the emotional impact of the disease, adapting to new roles and responsibilities related to diabetes management, and navigating social and family relationships. The Neuman Systems Model views individuals as a system of interacting parts, including physiological, psychological, sociocultural, and spiritual components. Diabetes can disrupt the balance of these components and create stressors, such as managing the physical and emotional symptoms of diabetes, coping with the impact on social and cultural norms, and maintaining spiritual and emotional well-being.

In conclusion, the pathophysiology of diabetes involves complex physiological processes and can lead to a range of complications. Variations in findings over time can be attributed to advances in medical research and technology. Nursing conceptual models can be used to understand the adaptation and stressors of living with diabetes and provide a framework for system analysis.
