🔬 Medical science
The kidneys filter waste from the blood, balance fluids and electrolytes, regulate blood pressure, and help produce red blood cells and active vitamin D.
Common causes of kidney disease are diabetes, hypertension, glomerulonephritis, polycystic kidney disease and infections. Diagnosis uses blood (creatinine, eGFR), urine tests and imaging; treatment ranges from blood-pressure and glucose control to dialysis and transplantation.
🧩 The GNM model
Claimed conflict: GNM links the renal collecting tubules to an "existence / abandonment (refugee) conflict" and to feeling "like a fish out of water," with associated water- and fluid-retention themes.
Germ layer & brain relay (GNM model): GNM classes the renal collecting tubules as endoderm controlled from the brainstem, and the kidney parenchyma as new mesoderm controlled from the cerebral medulla.
Two-phase course (claimed): GNM claims the collecting tubules retain water during the conflict-active phase (the "Syndrome") and that the parenchyma loses tissue in activity and replenishes — with swelling — during healing.
