    Study Notes

    Endocrine Disorders in Pregnancy

    • Endocrine disorders often involve hormone imbalances, either too much or too little secretion.
    • Common endocrine diseases in pregnancy include hypersecretion (too much hormone) and hyposecretion (too little hormone), and diabetes and thyroid disease are the most common.

    Gestational Diabetes Mellitus

    • Pathologic changes and defective insulin secretion, as well as peripheral insulin resistance, impact glucose control during pregnancy.
    • Insulin resistance increases during pregnancy.
    • Incidence: 2-3% of pregnant women develop gestational diabetes.
    • This usually resolves after childbirth, but it's a risk factor for developing type 2 diabetes later in life (50-60%).

    Thyroid Diseases

    • Normal pregnancy: Thyroid gland enlarges (thyromegaly).
    • Hypothyroidism: Risk for anovulatory menstruation and spontaneous abortion, as thyroid hormone is critical for pregnancy maintenance.
    • Treatment with levothyroxine, a synthetic thyroid hormone. Increased dosage (25-30%) is often needed during pregnancy.
    • Hyperthyroidism: Hypermetabolism, often displayed by heat intolerance, tachycardia (rapid heart rate), and weight loss. Other potential complications include heart failure, preterm labor, and intrauterine growth restriction (IUGR).
    • Treatment usually involves medication like methimazole or PTU, which crosses the placenta potentially causing congenital hypothyroidism or goiter.
    • Thyroid medication must be carefully monitored within a low range to avoid potentially severe outcomes.

    Risks During Pregnancy

    • Gestational Diabetes Mellitus: Risks include macrosomia (large baby), polyhydramnios (excess amniotic fluid), and complications during labor.
    • Thyroid Diseases: Risks with poorly controlled thyroid disease include anovulatory menstruation and spontaneous abortion.
    • Poorly controlled hyperthyroidism can increase risk for maternal and fetal complications.

    Impaired Glucose Tolerance/Homeostasis

    • Impaired fasting glucose (110-125 mg/dl)
    • Impaired glucose tolerance (140-200 mg/dl)

    Gestational Diabetes Mellitus Diagnostic Findings

    • Oral Glucose Tolerance Test (OGTT): screening done typically at 24-28 weeks gestation evaluates blood glucose levels after glucose intake.

    Gestational Diabetes Mellitus Classifications

    • Type 1: insulin-dependent diabetes; beta cell destruction.
    • Type 2: non-insulin dependent diabetes; insulin resistance.

    Gestational Diabetes Mellitus Management

    • Diet modification, exercise, and in some cases, insulin therapy help manage gestational diabetes.

    Asthma

    • Management often involves corticosteroids, mast cell stabilizers, beta-agonists, and leukotriene receptor antagonists.

    Anemia in Pregnancy (Iron Deficiency Anemia)

    • Physiological anemia: temporary dilution of red blood cells during pregnancy.
    • Pathologic anemia: true anemia, caused by disorder of erythropoiesis, or excessive RBC loss due to bleeding or destruction.
    • Most common during pregnancy: iron deficiency anemia, characterized by low blood hemoglobin levels, microcytic, hypochromic RBCs.

    Anemia in Pregnancy (Megaloblastic Anemia - Folate Deficiency)

    • RBCs are abnormally large, and macrocytic with increased MCV.
    • Folic acid deficiency.
    • Treatment: daily supplementation.

    Pregnancy With Left-Sided Heart Failure

    • Classification (NYHA): evaluates the severity of functional limitation.
    • Clinical findings: pulmonary edema (fluid in lungs), dyspnea, orthopnea (difficulty breathing when lying down), paroxysmal nocturnal dyspnea (PND), tachycardia.
    • Management: diuretics, antihypertensives, anticoagulants.

    Pregnancy With Right-Sided Heart Failure

    • Clinical findings: systemic vascular congestion, jugular venous distention, hepatosplenomegaly, ascites, peripheral edema, and weight gain.
    • Management: aims to improve heart function and reduce congestion, often with diuretics and other medications.

    Venous Thromboembolism (VTEs) During Pregnancy

    • Increased risk during pregnancy due to venous stasis, vessel injury, and hypercoagulability.
    • Prevention: early ambulation, compression stockings, and in some cases anticoagulation therapy.

    Sickle Cell Anemia

    • Inherited hemolytic anemia, affecting red blood cells.
    • Abnormal hemoglobin S causes red blood cells to assume a crescent or sickle shape.
    • Common complications include severe anemia caused by rapid hemolysis and decreased RBC lifespan; and organ damage leading to vaso-occlusive crisis.
