All are true about gestational diabetes except :
**Core Concept**
Gestational diabetes mellitus (GDM) is a type of diabetes that develops during pregnancy, typically in the second or third trimester. It is characterized by insulin resistance and impaired insulin secretion, leading to hyperglycemia. The exact pathophysiology involves the placenta's production of various hormones that interfere with insulin signaling.
**Why the Correct Answer is Right**
The correct answer is not provided in the question, but we'll analyze the typical options. Gestational diabetes is indeed associated with increased risk of macrosomia, maternal and fetal hypoglycemia, and the need for insulin therapy or oral hypoglycemic agents. These complications arise due to the placental hormones' impact on insulin sensitivity and beta-cell function.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided, so we'll proceed with the typical distractors. Let's assume **Option A:** "Gestational diabetes is a rare condition." This statement is incorrect because GDM affects approximately 9.2% of pregnancies worldwide, making it a relatively common condition.
**Option B:** "Gestational diabetes resolves after delivery." This statement is incorrect because women with a history of GDM are at increased risk of developing type 2 diabetes later in life. The risk is estimated to be 7-10 times higher compared to women without a history of GDM.
**Option C:** "Gestational diabetes is not a risk factor for type 2 diabetes." This statement is incorrect because women with a history of GDM are at increased risk of developing type 2 diabetes, as mentioned earlier. This risk persists even after adjusting for other risk factors.
**Option D:** "Gestational diabetes is a risk factor for fetal macrosomia." This statement is correct, but since we're looking for the exception, let's assume **Option D** is the correct answer.
**Clinical Pearl / High-Yield Fact**
Women with a history of GDM should undergo regular screening for type 2 diabetes and cardiovascular disease, as they are at increased risk of developing these conditions later in life. A 75-g oral glucose tolerance test (OGTT) is recommended for screening at 6-12 weeks postpartum.
**Correct Answer:** None provided.
