What is ibs?
Irritable bowel syndrome (IBS) is a chronic disorder of the gut-brain axis characterized by recurrent abdominal pain linked to changes in bowel habits — diarrhea, constipation, or both. It affects about 10% of US adults and is more common in women.
IBS isn't dangerous and doesn't damage the GI tract, but it can significantly disrupt life. The good news: most people improve substantially with a structured combination of dietary changes (particularly low-FODMAP), medications, and stress management.
Diagnosis is based on symptoms after ruling out red flags. A clinician can help work through the standard approach and prescribe what's appropriate for your subtype (IBS-D, IBS-C, or mixed).
Do I have ibs? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
The exact cause isn't fully understood, but altered gut motility, visceral hypersensitivity (gut nerves overreact), gut microbiome differences, and gut-brain communication issues all play a role. Post-infectious IBS (after a GI infection) is well-documented. Stress, anxiety, and depression strongly influence symptoms.
Is it contagious?
No, IBS is not contagious — but post-infectious IBS can develop after a contagious GI illness.
IBS isn’t imaginary — it’s a real disorder of how the gut and brain communicate. And the treatments are real, too.
Can it be treated online?
Classic IBS without red flags is well-suited to telehealth. A clinician evaluates your symptom pattern, screens for warning signs, and works through a treatment plan. Telehealth is NOT appropriate if you have rectal bleeding, unintentional weight loss, family history of colon cancer, onset after age 50, fever, anemia, or nocturnal symptoms that wake you from sleep — those need in-person workup.
How ibs is treated
Treatment is tailored to subtype. For IBS-D: loperamide, low-dose tricyclic antidepressants (amitriptyline, nortriptyline), rifaximin, or bile acid sequestrants. For IBS-C: linaclotide, lubiprostone, or plecanatide. Antispasmodics (dicyclomine, hyoscyamine) help with pain. The low-FODMAP diet reduces symptoms in about 70% of people. Peppermint oil capsules can help. Gut-directed hypnotherapy and CBT have strong evidence for refractory cases.
Self-care while you wait
- Try a low-FODMAP elimination diet (work with a dietitian when possible)
- Identify your personal triggers — common ones: lactose, fructose, sorbitol, wheat, onions, garlic
- Eat regular meals, don’t skip
- Stay hydrated
- Limit caffeine and alcohol if they’re triggers
- Manage stress — IBS responds to it
- Soluble fiber (psyllium) often helps; insoluble fiber (bran) can worsen IBS
- Regular exercise improves symptoms
How long does it last?
IBS is chronic and usually lifelong, with flares and quieter periods. Most people significantly improve with the right combination of diet, medication, and stress management — though some symptoms typically persist.
Frequently asked questions
How is IBS diagnosed?
Mostly clinically — based on the Rome IV criteria (recurrent abdominal pain at least 1 day/week for 3 months, related to defecation or change in stool form/frequency) after ruling out red flags. Tests are mainly to exclude other conditions.
Is IBS the same as IBD (Crohn’s, ulcerative colitis)?
No — IBD is inflammatory damage to the gut wall, visible on scope and biopsy. IBS doesn't cause inflammation or damage. Bloody stools, weight loss, fever, and night-waking symptoms suggest IBD, not IBS.
Will probiotics help?
Mixed evidence. Some specific strains (like Bifidobacterium infantis 35624) have modest evidence for IBS. Trying for 4 weeks is reasonable — discontinue if no benefit.
Is low-FODMAP a forever diet?
No — it's an elimination diet (4–6 weeks) followed by reintroduction to identify your specific triggers. Staying strict long-term isn't recommended.
Why are antidepressants used for IBS?
Low-dose tricyclics (amitriptyline) reduce visceral pain and slow gut motility — helpful for IBS-D. SSRIs can help with IBS-C and the anxiety/depression that often accompany IBS. Doses are usually much lower than for depression.
