Treatment of Stomach Cramps in Adults Without Underlying Medical Conditions
For an otherwise healthy adult with stomach cramps, first-line treatment should be antispasmodic medications (such as dicyclomine, hyoscyamine, or peppermint oil) combined with dietary modifications including small frequent meals and avoidance of high-fat foods. 1
Initial Assessment and Red Flags
Before initiating treatment, exclude alarm features that require urgent investigation:
- Age >50 years with new-onset symptoms, unintentional weight loss, nocturnal diarrhea, rectal bleeding, family history of GI malignancy or inflammatory bowel disease 1
- Fever, peritonitis signs, blood loss, delirium, or abdominal cramps not relieved by loperamide (if diarrhea present) 2
- Severe dehydration, persistent vomiting with reduced urine output, or inability to eat 2
If any red flags are present, obtain complete blood count, comprehensive metabolic panel, inflammatory markers (CRP), and consider imaging with CT abdomen/pelvis with IV contrast before empiric treatment. 1, 3
First-Line Treatment Approach
Dietary Modifications
- Eat small, frequent meals rather than large meals 1
- Avoid high-fat foods, limit caffeine and alcohol, ensure adequate hydration 1
- Consider identifying specific food triggers: dairy products, wheat/gluten, high FODMAP foods 1
Pharmacologic Management
- Start with antispasmodics as first-line pharmacologic therapy: dicyclomine, hyoscyamine, or peppermint oil 1
- Over-the-counter symptomatic therapy is appropriate for mild patient-reported symptom severity 2
Critical caveat: Avoid NSAIDs (like naproxen or ibuprofen) for functional abdominal cramping, as they can cause stomach pain, ulcers, and bleeding in the stomach and intestines. 4
Second-Line Treatment for Refractory Symptoms
If symptoms persist after 8-12 weeks of first-line therapy:
Neuromodulator Therapy
- Initiate low-dose tricyclic antidepressants (TCAs) such as amitriptyline 10-25 mg at bedtime, titrating slowly based on response 1, 5
- Alternative: SNRIs such as duloxetine if TCAs are not tolerated or for more severe symptoms 2, 1, 5
- TCAs work through descending pain modulation pathways and can reduce visceral hypersensitivity 2
Dietary Escalation
- Consider supervised low FODMAP diet with a trained dietitian as second-line dietary therapy 1
- Add soluble fiber supplementation such as ispaghula 1
Psychological Interventions
For severe or refractory cramping pain:
- Initiate cognitive behavioral therapy (CBT) early, alongside medical therapy, to address catastrophizing and pain-related fear avoidance 1, 5
- Offer gut-directed hypnotherapy for patients with visceral hypersensitivity and somatic symptoms 1, 5
- Consider mindfulness-based stress reduction for psychological stress management 5
These psychological interventions have strong evidence for global symptom improvement and should not be delayed until after prolonged medication trials. 2, 5
Critical Pitfalls to Avoid
- Never prescribe opioids for functional gastrointestinal cramping pain, as they worsen outcomes and risk narcotic bowel syndrome 3, 5, 6
- Do not continue invasive testing once functional diagnosis is established with normal basic laboratory workup 5
- Avoid dismissing symptoms as "psychological" in a pejorative sense; explain that pain is real but involves central amplification mechanisms requiring brain-gut axis treatment 5
- Do not use NSAIDs chronically for abdominal cramping, as they directly cause stomach pain, ulcers, and GI bleeding 4
When to Refer to Gastroenterology
- Alarm features present after initial assessment 1
- Diagnostic uncertainty exists after initial workup 1
- Failure to respond to first-line therapies within 8-12 weeks 1
- Consideration needed for endoscopy if age >50 with new symptoms or family history of GI malignancy 1
Treatment Algorithm Summary
- Mild symptoms: Dietary adjustments + over-the-counter antispasmodics 2, 1
- Moderate symptoms: Prescription antispasmodics + dietary modifications + consider early CBT 1
- Severe/refractory symptoms: Add low-dose TCAs or SNRIs + gut-directed hypnotherapy + multidisciplinary pain management without opioids 1, 5, 6
The foundation of all treatment is establishing a collaborative, empathic patient-provider relationship that acknowledges pain is real and multifactorial. 5
