Are you taking levothyroxine for hypothyroidism but still not feeling better? In this informative video, we dive deep into the reasons why levothyroxine may not be working effectively, even at high doses.Discover the common culprits behind persistent hypothyroid symptoms, including malabsorption issues caused by medications, supplements, foods, infections like H. pylori, and conditions affecting nutrient absorption. We'll also explore rare cases of tissue resistance to levothyroxine and pituitary or TSH-secreting tumors.Beyond absorption problems, you'll learn about factors that can interfere with thyroid lab tests, such as antibodies against thyroid hormones or heterophilic antibodies, leading to inaccurate results. We'll also discuss the possibility of medication errors or pseudo-malabsorption due to non-compliance.If you've been struggling with hypothyroidism despite taking levothyroxine, this video will provide valuable insights into potential underlying causes and solutions. Don't miss this comprehensive exploration of why levothyroxine sometimes doesn't work as expected, and what steps you can take to get your thyroid health back on track.
