Final answer:
Insulin needs generally decrease after delivery in patients with Type 1 diabetes due to reduced insulin resistance postpartum, but breastfeeding status can also affect glucose metabolism and insulin requirements.
Step-by-step explanation:
After delivery in a patient with Type 1 diabetes, the need for insulin generally decreases. During pregnancy, insulin resistance increases, which means that higher levels of insulin are often required to maintain blood glucose levels. However, after giving birth, insulin resistance quickly diminishes, leading to a reduced need for insulin. It is also essential to note that insulin needs may vary based on breastfeeding status, as lactation can influence glucose metabolism. Patients should closely monitor their blood sugar levels and consult with their healthcare provider for proper insulin dose adjustments postpartum.
