Objective: The aim of our study was to investigate the relationship between missed abortion and serum trimethylamine N-oxide (TMAO) levels.
Methods: A total of 129 patients with 56 missed abortions and 73 healthy pregnancies were included in our study. Patients who had more than one pregnancy loss, had systemic disease (hypertension, diabetes, rheumatologic disease, hematologic disease, and so forth) and did not accept to participate in the study were excluded.
