O que é Cálculo de Dose de Insulina?
O cálculo de dose de insulina é um método usado por pessoas com diabetes para determinar a quantidade de insulina necessária antes das refeições. Combina dois componentes: a dose de carboidratos (baseada na quantidade de carboidratos que será consumida) e a dose de correção (para ajustar a glicemia atual ao valor alvo). Este método é fundamental para o controle glicêmico adequado e prevenção de complicações do diabetes.
Perguntas Frequentes
How is basal insulin dose calculated?
Basal insulin is typically 40-50% of the total daily insulin (TDI) requirement. TDI is estimated at 0.5-0.8 units/kg/day for type 1 diabetes and 0.3-0.5 units/kg/day for type 2 diabetes. This calculator provides an initial estimate that should be individualized.
What is the correction factor (insulin sensitivity)?
The correction factor, or insulin sensitivity factor (ISF), indicates how much 1 unit of rapid-acting insulin will lower blood glucose. It is calculated as 1700/TDI (rapid analogs) or 1500/TDI (Regular insulin). This helps correct high blood glucose levels.
How do I calculate mealtime insulin (bolus)?
Mealtime insulin is calculated based on carbohydrate ratio (grams of carbohydrate covered by 1 unit of insulin) plus correction dose if blood glucose is above target. The calculator provides these values based on the TDI method.
Can I use this for children with diabetes?
Yes, but pediatric patients often require higher insulin doses per kg (especially during growth spurts and puberty). Typical TDI in children is 0.7-1.0 units/kg/day. Always consult with a pediatric endocrinologist for pediatric dosing.
