Let's make another run at a GI tweetorial here on ...

BILE ACID DIARRHEA

(10 tweets allowed) 2/
Bile acids are needed to absorb fats in the small intestine, but cause issues if they spill into the large intestine in large quantities.

Of course, the GI tract has a plan for this -->

Alright #MedTwitter, let's finish up the SIBO #MedTweetorial series with a discussion on treatment options.

SIBO - it's been fun, but it's time for you to go. Image 2/
Quick hits from last week's tweetorial on SIBO dx:

✅Breath test detects gas (hydrogen, methane) released by bacteria after carb intake (lactulose or glucose)
✅If gas above threshold (hydrogen rise ≥ 20 ppm or methane ≥ 10 ppm) --> positive test
✅Check for double-peak

Well that 1st GI tweetorial went well - thanks for all the feedback and engagement!

Let's get going with SIBO part II.

Today's focus? DIAGNOSIS! Image 2/
As a quick review, suspect SIBO in patients who endorse post-prandial abdominal gas symptoms (bloating, cramping, distension, flatulence) and diarrhea (typically watery; fatty in more severe cases).

** Also look for the distinctive pattern of low B12 and high folate **

I have learned so much from #MedTwitter. Time to start giving back.

Here we go with my first GI tweetorial.

Let's start talking SIBO (small intestinal bacterial overgrowth) - since we're all a little bloated at times. 2/

The colon is full of bacteria.

The small intestine should not be. When bacteria do proliferate in the small intestine (we'll discuss the reasons below), they can wreak a bit of havoc.

Why? Let's identify 3 processes.

A few years ago I became an attending and was struck by how hard it was to teach endoscopy. So I did a little #meded research with @GIMedEd and @BrighamGI to identify best practices.

Here’s what we found bit.ly/2SRtYYk

We first developed 18 endoscopy teaching competencies that spanned the endoscopy teaching encounter. We further refined this list after interviews with experts in the field.
