Secondary Iron Overload: Transfusions, Anemias, and Parenteral Iron
Acquired iron excess from transfusions, ineffective erythropoiesis, or IV iron—not classic HFE hepcidin failure. Phlebotomy often fails when anemia is present.

Prediabetes Progression and Screening: Catch the Window
FPG, A1C, and OGTT define the prediabetes band. Progression to T2D is common—and often preventable.

PBM vs Standard of Care in Diabetes: Honest Positioning
Lifestyle and proven drugs first. Light is experimental for glucose—stronger for some complications care pathways.

Non-HFE and Juvenile Hemochromatosis: HJV, HAMP, TFR2, Ferroportin
About 10–15% of inherited iron overload is non-HFE. Juvenile forms (HJV/HAMP) load fast with early heart and endocrine disease—negative HFE is not “not genetic.”

Microplastics Endocrine and Metabolic Effects: Particles vs Additives
Classic EDC additives (phthalates, bisphenols) have stronger human evidence than particle-specific endocrine claims. Keep parallel ledgers; avoid plastics-are-estrogen slogans.

Iron Overload Diet Modifiers: Alcohol, Vitamin C, Shellfish, Supplements
Diet is a modifier, not a cure. Phlebotomy removes ~250 mg iron per unit weekly; diet shifts absorption only a few milligrams per day.

MRI Liver Iron, Cardiac T2*, and When Biopsy Still Matters
MRI quantifies liver iron concentration and cardiac T2* noninvasively. In HFE HH, biopsy is mainly for fibrosis staging when ferritin exceeds 1000 µg/L or enzymes rise—not routine genetic diagnosis.

Iron Chelation and Special Cases: When Phlebotomy Is Not an Option
Deferoxamine, deferasirox, and specialty pathways for transfusional overload—chelation when blood removal is impossible, not a wellness detox.

Insulin Resistance Pathophysiology: Muscle, Liver, Fat, and Signaling
IR is impaired insulin action in muscle, liver, and adipose—ectopic lipid, inflammation, and β-cell compensation explain the arc to T2D.

HFE Genetic Testing Workflow: Who to Test and How to Interpret
HFE genotyping follows elevated iron studies or first-degree relatives of known HH—not unselected population screening. Homozygotes, compound hets, and simple hets map to different next steps.

Metabolic Health
Hemochromatosis Screening: Family Cascade vs Population Genetics
Screen first-degree relatives with iron studies plus HFE testing. Societies recommend against universal population genotype screening because penetrance is incomplete.

Diet Patterns, Weight, and Insulin Resistance: What Moves the Needle
Energy deficit and dietary patterns that cut ectopic fat beat miracle macros. Mediterranean-style and structured programs have outcome data.

Diabetes Pharma Landscape Brief: Metformin, GLP-1, SGLT2
Standard-of-care drugs have hard outcome data. Know the classes before ranking experimental light.

Habits That Improve Insulin Sensitivity (2026)
First-line insulin sensitivity levers: walking after meals, resistance training, weight loss when indicated, sleep, and food pattern—drugs and gadgets ranked honestly.

The Lifestyle Levers That Lower Inflammation (2026)
Lifestyle levers that move inflammatory risk: smoking cessation, visceral fat loss, exercise, sleep, dietary pattern—supplements ranked last with honesty.

Sleep, Circadian Rhythm, and Insulin Resistance
Short sleep and night light are metabolic exposures—not soft lifestyle footnotes.

Jack Kruse Leptin Rx Graded: Real Hormone, Unproven Hypothalamic Surgery Metaphor
Leptin biology is Nobel-adjacent. The branded reset is not a validated LR cure pathway.

High Ferritin Without Iron Overload: Inflammation, NAFLD, and Other Mimics
Ferritin is an acute-phase reactant. High values ≠ automatic hemochromatosis.

hs-CRP and IL-6: Inflammation Markers Without Allergy Confusion
hs-CRP stratifies residual CV inflammatory risk. It does not diagnose food allergy or MCAS.
