The two feed each other: the negative intrathoracic pressure of a breathing event pulls stomach contents up, and nocturnal reflux fragments sleep in turn. Treating both together beats treating either alone.

A real cost of long-term acid suppression: B12 in food is protein-bound and needs stomach acid and pepsin to release it. Suppress the acid and that step stalls, which is why long-term PPI users need their B12 watched.
Long-term PPI (>1 yr) → reduced gastric acid → impaired Ca/Mg/B12 absorption → reduced BMD + fracture risk. FDA 2010 boxed warning. GERD step-up therapy should pair with bone health + Ca + D + deprescribing strategy.

GERD = LES barrier failure + delayed gastric emptying + reduced esophageal clearance + impaired mucosal defence. ACG 2022 ladder: lifestyle (weight loss / head-of-bed 15 cm / food diary) → H2RA / PPI 8 wk → refractory → vonoprazan / anti-reflux surgery. Barrett surveillance per ACG 2022.
Visceral fat is the mechanical upstream of reflux: raised intra-abdominal pressure pushes on the gastro-oesophageal junction, so weight and reflux symptoms move together — even a 5 kg loss measurably cuts nocturnal reflux.
Nocturnal reflux is an easily missed physical cause of insomnia: lying flat makes regurgitation easier and heartburn pulls the sleeper out of light sleep. Here, treating the reflux first works better than treating the sleep.
Reflux in pregnancy is common and not a diet slip: progesterone relaxes the lower oesophageal sphincter while the growing uterus raises intra-abdominal pressure. Both at once, which is why the third trimester is worst.
