Core Tip

Core tip: A part of functional dyspepsia (FD) patients were found with weight loss in recent studies. As an antidepressant, mirtazapine was found not only to alleviate symptoms associated with dyspepsia and depression linked to FD with weight loss, but also to significantly increase body weight (mainly the visceral fat in body fat). Moreover, the likely mechanism of mirtazapine action is the regulation of brain-gut or gastrointestinal hormone levels.
