Obesity is a complex, multifactorial disease that is highly prevalent in the United States. Obesity is typically classified by body mass index and the US Preventive Services Task Force recommends screening all patients 6 years or older for obesity. Evaluation includes a thorough history and physical examination as well as laboratory tests including hemoglobin A1c, comprehensive metabolic panel, lipid panel, and thyroid-stimulating hormone. Treatment involves a multidisciplinary approach including nutrition, physical activity, and behavioral therapy as well as pharmacotherapy and bariatric surgery when appropriate.

Disequilibrium of hormonal intercommunication between the maternal brain and the developing fetal-placental unit increases morbidity and mortality risk for the mother-baby dyad. As a novel yet temporary endocrine organ, the placenta serves as a physical and immunologic barrier that facilitates exchange of nutrients and elimination of fetal waste. Steroid and peptide-based hormones secreted by the placenta and other neuroendocrine organs induce adaptations in maternal physiology accommodating fetal growth and development and enabling lactation postpartum. Human placental growth hormone, a peptide hormone continuously secreted at increasing concentrations throughout pregnancy, is a primary determinant of maternal insulin resistance and gestational diabetes.

Metabolic bone diseases encompass a group of disorders characterized by abnormalities in bone metabolism, structure, or mineralization. These disorders negatively impact overall health and quality of life and place individuals at high risk for fracture, which may increase morbidity and mortality. Clinicians should understand who is at risk for these disorders, select individuals who warrant further workup, determine appropriate laboratory and imaging evaluation, interpret results in a clinical context, and choose an optimal management strategy based on the individual patient.

In this article, we will review common pituitary disorders. There are 6 hormones secreted by the anterior pituitary gland: thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, growth hormone, and prolactin. The posterior pituitary gland stores and releases the hormones made in the hypothalamus, oxytocin and antidiuretic hormone, based on the body's needs. This article will discuss the role of these hormones, conditions and symptoms that occur with elevated or reduced hormone levels, as well as the evaluation and treatment of these pituitary disorders.
