Briefy noted: EN Madva et al. Scand J Gastroenterol 2025 Aug 8:1-5. doi: 10.1080/00365521.2025.2544306. Online ahead of print. Pharmacologic neuromodulation for bloating.
This was a small retrospective study of consecutively referred patients with a DGBI (N = 77; ages 18-74, 87% female) to a tertiary neurogastroenterology clinic who were prescribed a neuromodulator for a primary complaint of bloating in 2016-2022. Duloxetine was the most commonly prescribed neuromodulator (n = 52, 67.5%).
My take: This study shows that neuromodulators are likely beneficial for bloating symptoms. Dr. Garza () previously noted that in patients with bloating “the typical increase in excess gas during bloating symptoms is only 22 mL.” Thus, “A lot of bloating symptoms are due to increased sensitivity and ‘weird gas handling.’ The latter could include compression of diaphragm rather than elevation.”
