A regular point of discussion here!
It is yet another mystery why the issues of taking levothyroxine in a fasting or non-fasting state, despite being discussed for decades, still require research like this.
I think the authors have tried to avoid actually patient blaming - nonetheless, I think quite a bit of the paper actually does point its finger at patients. Whether taking too close to food, or missing doses - or whatever.
I suggest that one reason is that few patients have ever had this issues properly explained by the healthcare system - pharmaceutical companies, GPs, pharmacists, specialists, etc.
We might get told to take it every day, at the same time, and away from food. But I doubt many have had someone explain the details. The need for consistent, accurate dosing, and not achieving that can result in a roller coaster of thyroid hormone levels.
The impact of breakfast - or even tea or coffee.
Actually pointing out things like the percentage effects on the dose.
Most if it is quite readable but it does suffer from a feeling of repetition.
Still, it upholds the tradition of thyroid papers - more research needed.
Breakfast Habits in Patients Using Levothyroxine: Patient Experiences and Preferences
In conclusion, our study highlights the significant challenges and burdens associated with postponing breakfast to adhere to the current recommendation for fasting LT4 ingestion, leading to nonadherence, irregular LT4 intake, and omitting breakfast with potential adverse effects on QoL and cardiovascular health. Given the clear preferences towards LT4 ingestion together with breakfast, further research into alternative nonfasting administration methods without compromising treatment efficacy is warranted.
