2026-06-272026-06-22 by Laurel Fitzhugh

Sublingual B12 raises blood numbers. It has never been shown to protect a single nerve. There is no reason to think it prevents permanent nerve damage.

PA and B12 Deficiency Run in Families

2026-06-052026-06-05 by Laurel Fitzhugh

Family sitting together in a forest with parents holding hands behind their children.

Pernicious anemia has documented familial prevalence. First-degree relatives of PA patients carry a risk four times higher than the general population, and among siblings the figure is higher still — roughly six times the baseline rate. This reflects shared genetic architecture that shapes immune function across generations. B12 deficiency more broadly also clusters in families … Read more

Misdiagnosis of PA, the Summary

2026-09-222026-02-27 by Laurel Fitzhugh

A Confused 19th-Century Disease Model Still Shapes Modern Care Pernicious anemia has been misunderstood since it was first described. That misunderstanding did not persist because of a lack of scientific progress, but because early observations hardened into a disease model that medicine never fully revised. The result is a condition that remains misdiagnosed, underdiagnosed, and … Read more

PHYSICIAN REFERENCE: Pernicious Anemia

2026-07-262026-01-23 by Laurel Fitzhugh

Pernicious anemia is a demyelinating neurological disease. Vitamin B12 malabsorption leads to central and peripheral nerve damage, neurological and psychiatric symptoms that often precede anemia, and recovery limits set by the biology of myelin repair rather than blood test normalization.

Pernicious Anemia Is Serious

2026-06-052025-12-27 by Laurel Fitzhugh

Pernicious anemia is a progressive neurological disease. Without adequate treatment, it causes permanent nerve and spinal cord damage. This guide explains what’s at stake, why early treatment matters, and how to stay motivated when care is difficult to obtain.

What Stops People from Getting Well?

2026-06-052025-12-27 by Laurel Fitzhugh

People with pernicious anemia often resist treatment even though the long term neurological and health consequences are horrible. This article examines the psychological, cognitive, and systemic barriers that delay care—and how those barriers compound neurological damage over time.
