Gastrointestinal malabsorption of thyroid hormone Many things interfere with levothyroxine L-T4 absorption, such as iron, bile acid—binding resins, cholestyramine and colestipol, over-the-counter drugs containing iron and calcium, gastric conditions such as achlorhydria, and food ingestion around the time L-T4 is taken. Many other drugs and conditions impair absorption of L-T 4. What is the study about? Coffee interferes with the intestinal absorption of levothyroxine.

What is known about the problem being studied? Many things interfere with gastrointestinal absorption of L-T 4 See Box The authors of this study have previously reported cases of delayed intestinal absorption of L-T 4 and have thus been more than usually attentive to this problem, eliciting detailed histories from their patients about the use of other drugs and the dietary habits patients follow when taking L-T 4.

What was the aim of the study? The authors found that several patients were consistently drinking coffee or espresso to facilitate swallowing L-T 4 pills or were taking L-T 4 with water followed shortly by drinking coffee or espresso, suggesting that this might be the cause of the problem. The study was designed to test gastrointestinal absorption of L-T 4 in patients taking L-T 4 while simultaneously drinking coffee or espresso. Who was studied?

The study subjects were eight patients, all of whom were women.
