Every condition, organized by body system — from normal anatomy and physiology through the full arc of dysfunction. Why it happens, why the symptoms appear, and what each medication does to fix it.
41 Heart & Blood Vessels The pump and the pipes. Anything that makes the heart squeeze less, the pipes narrow, or the rhythm misfire shows up here. ›
28 Lungs & Breathing How air gets in, oxygen gets to the blood, and CO₂ gets back out. Problems show up as cough, wheeze, short breath. ›
31 Hormones & Metabolism The body's chemical mail. Thyroid, blood sugar, stress hormones, sex hormones — all signal to keep you running. ›
42 Digestion & Liver Mouth → stomach → small bowel → colon. Plus the liver, gallbladder, pancreas that supply the chemicals to break food down. ›
17 Kidneys & Urinary Tract The blood filter. Decides what gets kept (water, salt, calcium) and what gets dumped (waste, drugs, excess acid). ›
28 Brain & Nerves The wiring and the controller. Headaches, memory, movement, mood — anything electrical upstairs sits here. ›
14 Bones, Joints & Muscle The frame and the cables. Aches, swelling, weakness, fractures, autoimmune attacks on joints. ›

18 Women's Health & Reproductive Cycles, pregnancy, perimenopause, the conditions that affect ovaries, uterus and breasts. ›
3 Men's Health & Reproductive Prostate, testes, hormones, sexual health, and the conditions that hit men harder or earlier than the rest of the body. ›
17 Skin, Eyes & Ears The outside layer and the sensors. Rashes, itching, red eyes, and ear trouble — the everyday things that send people to the clinic. ›
