Pregnancy stresses the heart, kidneys, and metabolism so hard that its complications predict a woman's cardiovascular and diabetes risk decades later. Maternal-fetal medicine specialist Kathryn Gray explains how plasma volume surges 50%, how preeclampsia's placental biology works, and why half of gestational diabetes cases become type 2 diabetes.
Physician-scientist Lloyd Klickstein maps the full arc of drug development, from spotting an unmet need to FDA approval, using the muscle drug bimagrumab as his case study. Paired with semaglutide, it cut body fat by 45.7% over 72 weeks (125:28), rivaling bariatric surgery, while exposing the economics of patents, manufacturing, and phase one risk.
Peter Attia says thyroid problems are hard to diagnose because T4, the hormone the gland secretes, is inactive until tissues convert it locally into T3. TSH only shows how hard the gland is being told to work, not what's happening inside organs, so both under-treating real disease and over-treating borderline labs, common in functional medicine, cause real harm.
Cardiologist Michael Davidson argues heart disease and Alzheimer's share a root cause: cholesterol mismanaged over decades, not years. His new CETP-inhibitor drug, obeticholic acid, cuts LDL by up to 50%, raises HDL 150%, and shows early signals of slowing Alzheimer's biomarkers in ApoE4 carriers (68:43).
High blood pressure above 120/80 doubles cardiovascular death risk with each 20 mmHg rise in systolic pressure, physician Peter Attia explains. He breaks down what the SPRINT and STEP trials proved about aggressive treatment, how to measure blood pressure correctly at home, and why weight loss, exercise, sleep, and sodium timing can lower it as much as medication.
Metabolic fatty liver disease now affects over 38% of adults worldwide, and physician Peter Attia frames the liver as a mirror of whole-body metabolic health. The disease moves through four stages, from metabolic stress to steatosis, steatohepatitis, and fibrosis, and the first three stages are largely reversible through weight loss, muscle gain, and cutting alcohol and liquid sugar calories.
