Diabetic fetopaty Flashcards
clinica (presente sia nel diabete mellito gestazionale che pregestazionale)
Diabetic fetopathy
Effects
Macrosomia: birth weight > 90th percentile or > 4000–4500 g (due to stimulated growth and adipogenesis) → increased risk of birth injuries (e.g., shoulder dystocia)
Polycythemia (per la carenza di ossigeno)
Neonatal hypoglycemia (minore di 50 mg/dl ) and other electrolyte imbalances (hypocalcemia, hypomagnesemia)
Respiratory distress (due to insufficient production of pulmonary surfactant)
Hypertrophic cardiomyopathy (polycythemia → redistribution of iron → iron deficiency in cardiac tissue and hypoxemia → impaired cardiac remodeling)
Polyhydramnios (fetal hyperglycemia → fetal polyuria)
Quando
Onset: second and third trimester
Fisiopatologia (ipossemia fetale!!)
Pathophysiology: chronic fetal hyperglycemia → fetal hyperinsulinemia + islet cell hyperplasia, insulin-like growth factor, and growth hormones → ↑ metabolic effects and oxygen demand → fetal hypoxemia
