Supplements and Treatment Guidance for Autoimmune Thyroid and Gastric Disorders

Hashimoto's thyroiditis, the leading cause of hypothyroidism in the United States, affects 5‑10% of the population, with women ten times more likely to develop the condition. Common symptoms include fatigue, weight gain, hair loss, and menstrual irregularities. Diagnosis relies on elevated TSH levels and the presence of thyroid antibodies. Functional‑medicine practitioners recommend zinc and selenium supplementation to support the conversion of T4 to active T3 and to lower thyroid antibodies, while antioxidants are suggested to counteract the heightened oxidative stress seen in patients.

Autoimmune gastritis, also known as autoimmune metaplastic atrophic gastritis, occurs when the immune system attacks cells of the stomach lining, leading to chronic inflammation and potential progression to atrophic gastritis. Symptoms are often chronic and erosive, including indigestion and nutrient malabsorption. Triggers that can exacerbate the condition include Helicobacter pylori infection, excessive alcohol consumption, NSAID use, and chronic stress. Management focuses on addressing these triggers and supporting gastric health through dietary adjustments and, where appropriate, targeted supplementation.
