Do you recommend restarting a GLP-1RA after bariatric surgery if the patient tolerated it before the surgery?
While there are no clear recommendations on whether/when to resume GLP-1 RA after bariatric surgery, current 2025 guideline statements (ASMBS, ADA, AACE, Obesity Society) and expert consensus documents suggest the following approach: Hold GLP-1RA in the acute perioperative period. For daily-dosed ...
How do you approach the management of older adult patients with coronary artery disease on aspirin who have developed intermittent diverticular bleeds?
This is a tough clinical scenario that comes up often in older adults. You will often have subspecialists involved and will need to adapt your approach to their management and communication styles. Generalists can add value here by looking at the whole picture and figuring out what matters most to t...
When starting GLP-1 R agonist therapy for weight loss purposes, how do you counsel patients on duration of treatment therapy?
I counsel people that I expect this to be lifelong therapy (similar to how we don't stop blood pressure medications when blood pressure comes down to normal on them because it will go back up, we don't stop GLP1RA when we get to our weight goals, as our weight will go back up when they are stopped)....
How do you counsel patients on semaglutide or tirzepatide in light of potential cancer risks?
Use of GLP 1 RAs has sky-rocketed in recent years due to what seems to be a positive class effect on T2DM, weight loss, renal outcomes, cardiac outcomes and hepatic outcomes. I am not aware of any signals of increased malignancy risk. A brief literature review found meta-analyses showing possible be...
How do you explain the use of an AI scribe to patients the first time it is used in their care?
I use an AI scribe in my outpatient clinic, and around 90–95% of my patients agree to it. I obtain consent at the start of each visit and make it clear that it's completely optional—that they can say no at the start or change their mind at any point in the visit, with no impact on their care. I also...
How do you decide between anticoagulation and observation for an incidentally detected subsegmental pulmonary embolism in elderly patients with a history of gastrointestinal bleeding?
We face this conundrum not infrequently because subsegmental emboli are subject to high inter-reader variability, and the accuracy of the finding in isolation is suspect (Batayneh et al., Blood 2023). I once mentioned this to a radiologist who reads CTAs and was told, tactfully, that I was full of i...
How do you decide between systemic vs. arterially directed therapies in the first line setting for unresectable HCC?
In IMbrave150, 63% of patients treated with atezolizumab/bevacizumab had extrahepatic spread of disease, and my recommendation for patients with extrahepatic involvement is for first line systemic therapy. For patients with unresectable disease without extrahepatic spread, we take a multi-disciplina...
In patients with F2/F3 fibrosis, would you start Resmetirom if they had normal liver enzymes?
Yes, it would be reasonable, especially if you can prove that they still have significant steatosis (such as a CAP of >300 db/m) or active MASH on liver biopsy, as Resmetirom works by directly removing fat from the liver. The lack of liver enzyme elevation is not a reliable sign to rule out steatohe...
What is your preferred approach in treating recurrent bleeding from GAVE?
If repeated APC has not helped, I ask our advanced endoscopists to perform RFA. If it is a nodular GAVE, then banding is another option.
What are your go-to medical management options for high ileostomy output in patients with >100 cm of remaining small bowel?
First of all, you have to make sure that the patient's liquid intake is not composed of free water but an electrolyte solution at least 50% of the time. Metamucil at night Nana flakes in a milkshake at night Medication stepwise: Maximize loperamide Add diphenoxylate Add a PPI to reduce acid secre...
