Improving early diagnosis of multiple endocrine neoplasia type 1 by assessing the gastrointestinal symptoms, hypercalcemia, and elevated serum gastrin.

Despite advancements in the field, early diagnosis of multiple endocrine neoplasia type 1 (MEN1) remains unachievable. This letter to the editor highlighted the importance of carefully assessing gastrointestinal symptoms, hypercalcemia, and elevated serum gastrin levels, as suggested by Yuan et al in their paper. They focused on a patient with recurrent abdominal pain and diarrhea whose diagnostic path led to establishing a MEN1 diagnosis within a year. This emphasized the need for clinicians to consider MEN1 in patients with similar presentations, particularly when gastrointestinal symptoms persist or recur after discontinuation of proton pump inhibitors, especially knowing that early recognition and intervention are crucial for improving patient outcomes.
