Myths and Facts About IBS

Separating Fiction from Reality for Houston Readers

Irritable Bowel Syndrome (IBS) is common—millions of people live with it, including many in Houston. But there’s still a lot of confusion about what IBS is and what it isn’t.

In this guide from Gastrodoxs.com, we’ll tackle the biggest myths about IBS, highlight facts vs fiction IBS symptoms, and share the truth about IBS triggers and treatment.

You’ll also get expert insights from Dr. Bharat Pothuri, a trusted Houston gastroenterologist, plus tips and links to trusted resources like the Mayo Clinic and NIDDK.

Section 1: What Is IBS?

IBS is a functional gut disorder. That means your digestive system looks normal on tests, but it doesn’t always work the way it should.

Common IBS Symptoms:

• Belly pain or cramps
• Bloating
• Constipation
• Diarrhea
• Or a mix of both

Fast Facts:

• IBS affects up to 15% of people worldwide
• Women are twice as likely to report symptoms
• It often begins before age 35
• Stress and food choices play a major role

“IBS is real,” says Dr. Pothuri. “It’s not just in your head—even though stress can make it worse.”

Section 2: Common Myths About IBS

Let’s clear up some of the biggest myths.

Myth 1: IBS Is All in Your Head

Not true. While stress can make it worse, IBS is a real physical disorder. It involves gut nerves, muscles, and bacteria—not just emotions.

Myth 2: IBS Only Affects Women

False. Men get IBS too. They just may be less likely to talk about it or seek help.

Myth 3: All Fiber Is Bad for IBS

Wrong. Some fiber (like soluble fiber) can help IBS symptoms. It’s insoluble fiber—like wheat bran—that may trigger issues for some people.

Myth 4: IBS and Lactose Intolerance Are the Same

Nope. Lactose intolerance is a dairy-specific issue caused by an enzyme problem. IBS is a broader condition with many triggers.

Section 3: IBS Symptoms – Fact vs Fiction

Understanding what IBS really looks like can help you manage it better—and explain it to others.

Section 4: IBS Triggers and Treatment – What’s True?

Understanding your triggers can help prevent flares. Here’s what to know:

Common Triggers:

• Stress or anxiety
• High-FODMAP foods (like onions, garlic, and beans)
• Greasy or fried foods
• Caffeine and alcohol
• Hormone shifts (especially during periods)

“It’s rarely just one thing,” says Dr. Pothuri. “Most people react to a combination of triggers.”

What Helps:

• Low-FODMAP diet – This eating plan removes hard-to-digest carbs. A dietitian can guide you.
• Fiber fixes – Soluble fiber (like psyllium) can ease both constipation and diarrhea.
• Probiotics – Certain strains like Bifidobacterium infantis may support a healthy gut.
• Medications – Some people need antispasmodics, laxatives, or anti-diarrheal meds.
• Stress relief – Yoga, deep breathing, or therapy can calm the gut-brain connection.

Section 5: What People Often Get Wrong About IBS

Misunderstanding 1: IBS Is Always Mild

Not true. For some people, IBS can be severe—limiting work, travel, or social plans.

Misunderstanding 2: IBS Can’t Be Managed Naturally

Not true. Changes in diet, exercise, and stress often reduce symptoms by half or more.

Misunderstanding 3: Only Doctors Can Help

Wrong. The best care is team-based. You, your doctor, a dietitian, and sometimes a therapist all play a part.

Other Myths to Ignore:

• “IBS is just gas.”
• “Only older people get IBS.”
• “It shows up on blood tests.”
• “You’ll never eat your favorite foods again.”
• “Over-the-counter meds fix everything.”

Section 7: How to Prevent IBS Flares

• Keep a food and symptom journal
• Eat small meals more often
• Drink plenty of water—at least 8 cups a day
• Stick to a regular sleep schedule
• Try deep breathing or meditation every day

Section 8: When to Call a Doctor

Some symptoms are not typical for IBS. Talk to a gastroenterologist if you have:

• Unexplained weight loss
• Blood in your stool or black, tarry stools
• Severe or sudden pain
• Nighttime symptoms that wake you up

“Don’t wait,” says Dr. Pothuri. “Getting help early can prevent serious issues.”
