What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fasting blood glucose levels

    A fasting blood sugar level measures the amount of glucose in blood after patient has not eaten for at least 8 hours. It is primarily used to screen for or monitor prediabetes and diabetes. Fasting glucose is categorized as follows: Normal: Less than 100 mg/dL (5.6 mmol/L), Prediabetes: 100 to 125 mg/dL (5.6 to 6.9 mmol/L), Diabetes: 126 mg/dL (7.0 mmol/L) or higher on two separate tests.

    Measured: 12 week

  2. Fasting Serum Insulin Levels

    A serum fasting insulin test measures the amount of insulin in patient's blood after an overnight fast. It is used to evaluate pancreatic function, investigate hypoglycemia, and identify early-stage insulin resistance.Standard Lab Range: 2 to 25uIU/mL. Interpretation: High Levels (Hyperinsulinemia): Usually indicate insulin resistance, where cells do not respond properly to insulin, forcing the pancreas to produce excess amounts. It can precede prediabetes and Type 2 diabetes by years, even when blood sugar remains normal. Other causes include obesity, polycystic ovary syndrome (PCOS), and Cushing's syndrome.Low Levels: Suggest impaired or destroyed insulin-producing pancreatic beta cells. Common causes include Type 1 diabetes, chronic pancreatitis, or advanced Type 2 diabetes where the pancreas is "burned out"

    Measured: 12 week

  3. Homeostatic Model Assessment of Insulin Resistance

    It is a widely used medical tool that estimates how effectively your body regulates blood sugar. It acts as an indirect, highly accessible indicator of insulin resistance, helping assess the risk of type 2 diabetes and metabolic syndrome. Interpretation: Optimal / Sensitive: Under 1.0. Your body is highly sensitive to insulin and manages glucose well.Early Insulin Resistance: 1.0 to 2.9 (or greater than 1.9, depending on the diagnostic criteria). Your body is starting to require more insulin to keep blood sugar stable.Significant Insulin Resistance: Above 2.9 (or as low as 2.5 for some populations, particularly in Asian demographics)

    Measured: 12 week

  4. Glycated Hemoglobin

    Glycated hemoglobin (HbA1c) is a blood test that measures your average blood sugar levels over the past 2 to 3 months. It checks how much sugar has bonded to your hemoglobin, and is primarily used to diagnose prediabetes and diabetes, Below 5.7%: Normal / Healthy 5.7% to 6.4%: Prediabetes 6.5% or higher: Diabetes (diagnosed on two separate tests)

    Measured: 12 week

Secondary outcomes (11)
  1. High-sensitivity C-reactive protein

    it is a specialized blood test that measures very low levels of C-Reactive Protein to detect chronic, low-grade inflammation in the body. Results generally fall into one of three cardiovascular risk categories:Low Risk: Less than 1.0 mg/L Moderate Risk: 1.0 to 3.0 mg/L High Risk: Greater than 3.0 mg/

    Measured: 12 week

  2. Neutrophil-to-Lymphocyte ratio

    The neutrophil-to-lymphocyte ratio (NLR) is a simple, readily available biomarker calculated by dividing your absolute neutrophil count by your absolute lymphocyte count from a routine Complete Blood Count (CBC). It serves as a strong indicator of systemic inflammation.Average Normal NLR: Between (0.78) and (3.53) (the population average typically sits around (1.65)).Elderly Adults (Over 75): Normal ranges can extend up to (8.80) due to natural immunosenescence (aging of the immune system). Elevated NLR: Ratios above the normal range usually indicate physiological stress, systemic inflammation, infection, or tissue damage. Markedly elevated scores (e.g.,(>9.0)) are often seen in severe acute conditions like sepsis

    Measured: 12 week

  3. Adiponectin

    Adiponectin is a protein hormone and adipokine produced primarily by fat cells (adipose tissue) that regulates glucose levels, fatty acid breakdown, and inflammation. It plays a crucial role in enhancing insulin sensitivity and protecting the body against metabolic diseases like Type 2 diabetes and cardiovascular disease.

    Measured: 12 week

  4. fetal Abdominal Circumference

    Fetal Abdominal Circumference (AC) is a routine ultrasound measurement used to monitor fetal growth, estimate fetal weight, and check for growth abnormalities. It is one of the most reliable indicators of a baby's weight and overall physical development during pregnancy. Typical Normal Ranges for the AC during the second and third trimesters include:20 Weeks: ~14.5 cm to 16.5 cm 28 Weeks: ~22.5 cm to 25.5 cm 34 Weeks: ~28.0 cm to 31.0 cm 36 Weeks: ~31.0 cm to 34.0 cm

    Measured: 12 week

  5. thickness of placenta

    Placental thickness generally increases linearly by about 1 mm per week of pregnancy, roughly correlating in millimeters to your gestational age in weeks (e.g., 30 mm thick at 30 weeks). A normal placenta typically reaches a maximum thickness of about 4 cm (40 mm) at full term.Abnormal placental thickness, measured via ultrasound can provide critical clues about maternal and fetal health. Thick Placenta (>4 cm): A placenta that is too thick can sometimes indicate underlying issues such as maternal diabetes, infection, fetal anemia, or issues with blood flow.Thin Placenta (<2.5 cm): A placenta that is unusually thin, especially in the third trimester, may be a sign of placental insufficiency (where the placenta doesn't provide enough blood and nutrients to the baby) or intrauterine growth restriction (IUGR).

    Measured: 12 week

  6. Amniotic Fluid Index

    The Amniotic Fluid Index (AFI) is an ultrasound measurement used to estimate the amount of amniotic fluid surrounding a baby in the womb. It serves as a vital indicator of fetal well-being and placental function. Low AFI (<5 cm): May indicate dehydration, placental issues, or potential issues with fetal kidney development. It often requires closer monitoring or additional testing.High AFI (>25 cm): May be linked to gestational diabetes, multiple gestations (e.g., twins), or fetal gastrointestinal/swallowing abnormalities.

    Measured: 12 week

  7. Gestational age at delivery

    For pregnancies complicated by gestational diabetes, the optimal gestational age for delivery is typically between 38 and 39 weeks for diet-controlled cases, and between 37 and 39 weeks for cases requiring medication or those with maternal complications. Blood Glucose Control: Women who require insulin or oral medications to regulate glucose generally require earlier delivery (37-38 weeks) compared to those managing through diet alone.

    Measured: 39 weeks

  8. Mode of delivery

    Well-Controlled GDM: If blood sugar levels remain stable and there are no signs of fetal distress, you may be allowed to wait for natural labor to begin up to week 40.Poor Control or Complications: If blood sugar is difficult to manage or the baby is growing too large, your healthcare team may advise an earlier delivery (e.g., at 38 weeks)

    Measured: 39 week

  9. Birth weight

    Babies born to mothers with Gestational Diabetes Mellitus (GDM) most frequently have higher-than-average birth weights (often between 3.2 kg and 3.7 kg), but can range anywhere from being larger than normal to smaller than average, depending on blood sugar management and placental health. 1. Macrosomia (Large for Gestational Age - LGA)Definition: Birth weight greater than 4.0 kg or above the 90th percentile for gestational age.IRisk: High birth weight can cause delivery complications, including shoulder dystocia (where the baby's shoulder gets stuck in the birth canal), and often requires a Cesarean section.2. Small for Gestational Age (SGA)Definition: Birth weight below the 10th percentile for gestational age.Incidence: .Risk: While less common than large size, impaired fetal growth can happen, particularly if the GDM causes complications with placental blood flow later in the pregnancy.

    Measured: 39 week

  10. Apgar score

    The Apgar score is a rapid, standardized assessment used to evaluate a newborn's health immediately after birth. It determines how well the baby tolerated the birthing process and how they are adjusting to life outside the womb. How It Is ScoredMedical staff assess five criteria (summarized by the mnemonic APGAR). Each criterion is assigned 0, 1, or 2 points.A - Appearance (Skin Color): 0 = Pale or blue; 1 = Pink body with blue extremities; 2 = Completely pink.P - Pulse (Heart Rate): 0 = Absent; 1 = Below 100 bpm; 2 = Above 100 bpm.G - Grimace (Reflex Irritability): 0 = No response; 1 = Grimace or weak cry to stimulation; 2 = Vigorous cry, sneeze, or cough.A - Activity (Muscle Tone): 0 = Limp or floppy; 1 = Some arm and leg flexion; 2 = Active, spontaneous movement.R - Respiration (Breathing): 0 = Absent; 1 = Slow, irregular, or weak cry; 2 = Strong, lusty cry. Understanding the Results:7 to 10: Reassuring (normal).4 to 6: Moderately abnormal.0 to 3: Critically low

    Measured: 39 week

  11. Rate of neonatal intensive care unit admission

    NICU admission rates and criteria vary based on location, gestational age, and specific birth circumstances.Conditions like gestational diabetes, pregnancy-induced hypertension (PIH), or infections (e.g., sepsis) frequently trigger the need for immediate newborn intensive care

    Measured: 39 week
