What the current semaglutide labels say
The current Wegovy label says semaglutide use has been associated with gastrointestinal adverse reactions, sometimes severe, and that Wegovy is not recommended in patients with severe gastroparesis. The Ozempic label carries similar severe-GI and delayed-emptying language. Those are the cleanest official starting points.
What the labels do not do is say that every case of constipation, bloating, or vomiting equals a bowel obstruction. That is why a careful page has to separate severe GI reactions from the narrower question of whether imaging, admission notes, or surgical evaluation pointed to obstruction or ileus.
What obstruction, ileus, and pseudo-obstruction mean
MedlinePlus explains that intestinal obstruction and ileus involve a blockage or failure of the intestines to move material through normally. Symptoms can include abdominal pain, swelling, vomiting, constipation, and inability to pass gas or stool.
NIDDK's pseudo-obstruction page matters because it explains that some patients can look obstructed even when no physical blockage is found. That distinction matters for records and for accuracy. A hospital note that says ileus or pseudo-obstruction is not interchangeable with a note that says bowel obstruction requiring surgery.
Why people search this after a GLP-1 injury
Severe vomiting, constipation, distention, dehydration, and delayed gastric emptying can overlap. That is why people who experienced a major GI event on semaglutide often search for obstruction even before they know what a clinician ultimately called it.
The most useful question is not what internet shorthand someone used. It is what the ER, admission team, surgeon, gastroenterologist, or radiologist wrote down. Imaging language, admission diagnoses, operative notes if any exist, and discharge summaries usually settle the question much faster than a broad symptom list.
What to document if obstruction was considered
Write down the semaglutide product used, dose changes, when the severe symptoms started, whether stool or gas stopped passing, whether vomiting became persistent, whether the abdomen became distended, and whether the person was admitted or transferred.
The most useful records are usually CT reports, abdominal imaging, admission notes, surgical consults, operative notes, GI consults, nasogastric tube notes if used, discharge instructions, and later follow-up that clarifies whether the final diagnosis was obstruction, ileus, pseudo-obstruction, gastroparesis, or something else.
