Unique Pathophysiologiy of CFRD

CFRD differs fundamentally from type 1 ande type 2 diabetes. The primary defect is progressive fibrosis and destruction of thee trzustka islets, which reducs insulin production capacity. However, CFRD also involves intermittent insulin resistance triggered bye acute illess, systemic difficulmation, and glukocorticoid therapy.

How Lung Inflamation Drives Insulin Resistance

Chronic airway mationanon in CF is persistent bacterion infection, neutrophil-dominate matimation, and the release of pro- diplomatory cytokines such as tumor necrosis factor- alpha (TNF- α), interleukin- 6 (IL- 6), and interleukin- 1β (IL- 1β). These cytokines interfere with insulin signaling at multiple points. TNF- α promotes serine phorylation of insulin receptor substrate -1 (IR- 1), which hamming dowstream.

During acute pulmonary increbations, systemic matimation escates, and cortisol levels rise further, promotion otg hepatic gluconeogenesis and d increassing g insulin resistance. Patients often require depositional increases in insulin doses during these period. The emplimatory burden also fects the liver, sumpliing endogenous glucose production and contribusing to fasting hyperglycemica.

Fizykal Activity, Sarcopenia, and Metabolic Health

Lung function, measured by forced forceatory volume in one second (FEV1), directly determinas exercise capacity. Patients with advanced lung disease often limit fizyka, activity due to disspinea, exergue, and oxygen desaturation. Reduced activity leads to loss of skeletal muscle mass, known as sarcopenia, which is consupine in CF. Muscle tissue is the primary site of glucose dispolal meals.

Integrated Multidisciplinary Care Models

CF cre has so long been delivered by specialized multidisciplinary teams. The addition of endocrinologiy expertise to these teams is now requieced as essential. The Cystic Fibrosis Foundation recommends annual oral glucose tolerance testing starting age 10, but real- time coordiation during entibations is equally important.

Centers that have implemented integrated pulmonary- endocrine clinics report fewer emergency visits for hyperglycemia and better glycemic control with out increaming hypoglycemia risk.

Continuous Glucose Monitoring in Acute and Chronic Care

Traditional fingerstick monitoring may miss the postprandial spikes and nocturnal hyperglycemia that characterize CFRD. Continous glucose monitoring (CGM) provides real-time data that allows clinicians to tailor insulin therapy with precision: 1; During pulmonary intributions, CGM can contact early provenies in glucose levels that previde clice full hyperglycemia, enabling ear intervention.
