The Claim

Women with levothyroxine-resistant hypothyroidism and Helicobacter pylori infection have significantly lower hemoglobin, hematocrit, red blood cell, and white blood cell counts compared to healthy controls.

In plain English

Women with both levothyroxine-resistant hypothyroidism and Helicobacter pylori infection have lower levels of hemoglobin, hematocrit, red blood cells, and white blood cells than women without these conditions.

See the scientific wording

Women with levothyroxine-resistant hypothyroidism and Helicobacter pylori infection exhibit significantly lower hemoglobin, hematocrit, red blood cell, and white blood cell counts than healthy controls, suggesting a combined impact of thyroid dysfunction and chronic infection on hematological parameters.

Why this might work

A stomach infection causes long-lasting inflammation that spreads through the body, which blocks the bone marrow from making enough red and white blood cells. At the same time, low thyroid hormone levels reduce the body's ability to use iron properly, so even when iron is present, it cannot be used to build blood cells. Together, these two problems cause blood cell counts to drop significantly.

  1. Study: Helicobacter pylori eradication effects on thyroid hormones and autoantibodies in levothyroxine-resistant hypothyroid women

    This study found that women with a stubborn thyroid condition and an H. pylori stomach infection had lower levels of red and white blood cells than healthy women, which matches the claim. It shows these two health problems together may hurt blood cell production.
