Lifestyle modifications for #GERD

Target to the patient!!!

WEIGHT LOSS is key. Image
Acid suppression: H2RA or PPI Image
PPIs are more effective than H2RAs for #GERD Image
PPIs really don't lose effect. ImageImageImage
Keep your 👁 out for potassium competitive acid blockers! ImageImage
Baclofen is effective in reducing TLESRs and reflux episodes. ImageImage
What about adjunctive therapy with bile acid binders?

Unfortunately, phase III study was discontinued 😔 Image
Alginates theoretically coat the esophagus and protect from acid. Unfortunately the data really don't support their use. ImageImage
ImageImageImage
Types III-IV hernias may need surgery. For I-II, assess symptoms and response to PPI. ImageImage
If PPIs are not helping, consider:
-alternative diagnosis
-medication nonadherence
-mechanical defect (suspect if pyrosis is better but still has regurgitation)
-"refractory #GERD"
- this should actually be "refractory symptoms," because may not actually be acid-related ImageImageImageImage
ImageImage
💎s on #GERD

-taper to lowest dose of acid suppression
-if not better, look for other diagnosis and/or mechanical defects (especially if regurgitation)
-surgical/endoscopic therapies ONLY when you can prove objective #GERD ImageImage

I gave a talk on inpatient bowel regimens today for the @YaleMed @YaleIMed residents and students, with additional 💎s on outpatient #constipation. Here are the slides!

Most inpatients require a bowel regimen. Our patients typically have most of the risk factors for #constipation!
#Constipation is more about symptoms than frequency! 🚽

It’s also a *symptom* (like chest pain), so need to figure out what’s causing it and treat accordingly.
