GI Bleed following Weight Loss Surgery

September 17, 2018 10:28 am

Gastrointestinal (GI) Bleed following weight loss surgery is rare but does require knowledge of the particular bariatric surgical procedure the patients has and how to proceed with diagnostics to fully evaluate the situation. Acute or chronic gastrointestinal bleeding can cause anemia in patients. However, Anemia may also be caused by nutritional deficiencies (iron, vitamin , minerals), Kidney disease, bone marrow disease  and others. The work-up for anemia following weight loss surgery follows a routine protocol. If there is an evidence of bleeding from intestine  (bloody emesis, bloody bowel movement, “tar” like black bowel movements) then the diagnostic work up would include an upper and lower endoscopy.

Endoscopic Procedures:

Upper endoscopy Esophagogastroduodenoscopy (EGD): evaluates the esophagus, stomach and a limited area of the duodenum past pyloric valve.

Lower endoscopy Colonoscopy or coloscopy: evaluates the rectus and the entire colon.

Between these two tests, there is still a considerable amount of the small bowel that is not accessible or visualized with endoscopic procedures. For the small bowel, examination Capsule endoscopy is an option in an intact GI tract. Patients who have had Gastric bypass RNY or the Duodenal Switch, the large segments of the small bowel can not be visualized or examined with capsule endoscopy.

Patients who have had Duodenal Switch, Gastric Bypass and SADI – S would need a tagged red cell scan or CT angiography if GI bleed is suspected in areas of the small intestine that are inaccessible by endoscopic procedures.

Vitamin A injections

October 25, 2017 10:31 am

Unfortunately, we have been informed that the company we order our Vitamin A injectionsVitamin A injections from will no longer have Vitamin A available.  We have contacted several other companies and they also do not have it available.  The manufacturer of Vitamin A states that there is a nationwide shortage of injectable Vitamin A and it may be available next year.

Our office has a few vials left and we are hoping that we can get to as many people as possible before we are completely out.  We will continue to look for a source of Vitamin A injections. We will let you know when it is no longer available and when we receive a new shipment.   Thank you for your understanding and we apologize for this issue.
