    Study Notes

    Reflux/Heartburn

    • Caused by stomach acid rising into the esophagus.
    • Many contributing factors.

    Ulcers

    • Erosions of the GI tract (alimentary canal).
    • Most common in the lower esophagus, stomach, and small intestine.
    • Typically less than 1 inch wide.
    • If left untreated, contents of the lumen may leak into the body cavity.
    • According to the CDC, almost 6% of Americans (14.8 million people) are diagnosed with peptic ulcers each year.

    Obesity

    • Defined as having a body weight higher than what is considered normal for a given height.
    • New CDC data from 2023 show that in 23 states, more than one in three adults (35%) has obesity.

    Obesity Statistics

    • Around 1 in 3 adults (30.7%) are overweight.
    • More than 2 in 5 adults (42.4%) are obese.
    • About 1 in 11 adults (9.2%) have severe obesity.
    • About 1 in 6 children and adolescents aged 2 to 19 (16.1%) are overweight.
    • Almost 1 in 5 children and adolescents aged 2 to 19 (19.3%) are obese.
    • About 1 in 16 children and adolescents aged 2 to 19 (6.1%) have severe obesity.

    Ozempic

    • Other names for this medication class include:
      • Glucagon-like peptide-1 agonists.
      • GLP-1 receptor agonists.
      • Incretin mimetics.
      • GLP-1 analogs.
    • GLP-1 agonist medications work by mimicking the GLP-1 hormone.
    • An agonist is a substance that attaches to a cell receptor and causes the same action as the naturally occurring substance.
    • GLP-1 medications bind to GLP receptors to trigger the effects (or roles) of the GLP-1 hormone.
    • The higher the dose of the GLP-1 agonist, the more extreme the effects.
    • The satiety effect of GLP1-agonists reduces your food intake, appetite, and hunger, leading to weight loss.
