NSAID Enteritis

Yes. NSAIDs can injure the small intestine and cause increased permeability, inflammation, erosions, ulcers, bleeding, protein loss, diaphragm-like strictures, obstruction, and rarely perforation. This is often called NSAID enteropathy.

No NSAID is universally safest. Some COX-2-selective strategies may lower certain upper gastrointestinal risks, but small-bowel, cardiovascular, and kidney risks remain. Choice, dose, duration, and protective therapy require individualized prescribing.

When medically safe, the central step is stopping or reducing the causative NSAID with prescriber guidance. Care may also treat anemia, protein loss, ulcers, or bleeding. Fixed strictures may require endoscopic dilation or surgery. No single medicine reliably treats every case.

Inflammation and superficial ulcers may improve after the drug is withdrawn, but scar-based diaphragm strictures may persist. Healing depends on injury depth, continued exposure, nutrition, blood flow, and whether complications have developed.

Pain may be vague, cramping, burning, meal-related, or absent. Severe colicky pain with bloating and vomiting can suggest narrowing or obstruction. Symptoms alone cannot reliably separate NSAID injury from Crohn’s disease, infection, or another disorder.

Risk varies by outcome and patient. A drug with lower stomach-ulcer risk may still affect the small bowel, heart, or kidneys. The safest choice may be avoiding an NSAID, using a topical option, or selecting another pain strategy after clinician review.

Gastritis involves the stomach, while NSAID enteritis involves the small intestine. Stomach injury may improve with supervised NSAID changes and acid suppression, but those measures do not guarantee small-bowel protection. Bleeding or severe pain needs prompt assessment.

Many people have no clear symptoms. Possible signs include abdominal pain, bloating, diarrhea, fatigue from iron-deficiency anemia, black stool, low albumin, swelling, weight loss, or obstruction symptoms such as vomiting and inability to pass gas.

Yes, low-dose aspirin can contribute to small-bowel mucosal injury and bleeding. However, it may be essential for heart or stroke prevention, so it should not be stopped without advice from the clinician who prescribed it.

No. They can reduce acid-related injury in the stomach and duodenum but do not reliably protect the jejunum or ileum. Some studies raise concern that microbiome changes may influence enteropathy, but individual treatment decisions require clinical context.

Yes. Slow blood loss from small-bowel erosions or ulcers can cause iron-deficiency anemia without visible bleeding. A blood count and iron studies help identify the pattern, and further testing may be needed to locate the source.

Yes. Both can cause ulcers, inflammation, anemia, and strictures. Medication timing, lesion shape and distribution, imaging, biopsy, other Crohn’s features, and improvement after supervised NSAID withdrawal help distinguish them.

A capsule can become trapped behind a stricture. When obstruction or diaphragm disease is possible, clinicians may use CT or MR enterography or a dissolvable patency capsule before standard capsule endoscopy.

Contact the prescriber promptly and avoid taking extra doses beyond instructions. An over-the-counter NSAID may be replaceable, but prescribed aspirin or anti-inflammatory therapy can have important cardiovascular or disease-control reasons that make unsupervised stopping unsafe.

Yes. Repeated injury and healing can create thin circumferential diaphragm strictures. Severe cramping, progressive swelling, repeated vomiting, or inability to pass stool or gas requires urgent evaluation.
