GI Myth Busting: What’s True and What’s Not About Your Digestive Health

Sep 27, 2025

Digestive health is surrounded by myths, and social media often makes the confusion worse. At our Brooklyn gastroenterology practice, Dr. Jack Husney sees patients every day who have tried “gut health hacks” or dismissed symptoms because of misinformation. Here are five of the most common myths — and the real facts you need to know.

Heartburn and Milk

Many people reach for a glass of milk when they have heartburn. While it may soothe temporarily, milk often makes symptoms worse later. The proteins and fats in milk stimulate the stomach to produce more acid, which can aggravate reflux once the initial cooling effect wears off.

If you’re experiencing frequent heartburn — more than twice a week — this may be a sign of gastroesophageal reflux disease (GERD). Left untreated, GERD can lead to esophagitis, narrowing of the esophagus, or even Barrett’s esophagus, which is precancerous. If you have ongoing reflux, it’s important to see a Brooklyn gastroenterologist like Dr. Jack Husney for proper evaluation and treatment, rather than relying on milk or other home remedies.


Colon Cancer Is Only in Older Adults

It used to be thought that colon cancer mainly affected people over 50. Today, however, the fastest-growing group of new colon cancer diagnoses is in adults under 50.

Because of this trend, the American Cancer Society and other expert groups recommend starting colonoscopy screening at age 45 — and earlier if you have a family history or genetic risk factors. Colonoscopy is not just diagnostic; it is preventive. Precancerous polyps can be identified and removed before they turn into cancer.

At our office in Brooklyn, Dr. Jack Husney stresses that assuming younger people are “safe” from colon cancer is a dangerous myth. If you’re overdue for screening, or have rectal bleeding or changes in bowel habits, schedule your colonoscopy today.


Detox Cleanses Reset the Gut

“Detox” teas, juices, and cleanses are heavily promoted on TikTok and Instagram, but they don’t actually reset your digestive system. Your liver and kidneys already detoxify your body naturally, every single day.

Extreme cleanses can be harmful, causing dehydration, loss of electrolytes, dizziness, and in some cases hospitalization. Instead of spending money on risky cleanses, support gut health by focusing on a balanced diet, hydration, fiber, exercise, and quality sleep.

Patients often ask Dr. Husney about gut resets, but the reality is: the safest way to protect your digestive system is with science-based habits and regular GI checkups, not fad detoxes.


Probiotics Cure Everything

Probiotics are everywhere, with claims they can fix everything from bloating to mood disorders. While probiotics do have real benefits — for example, reducing diarrhea after antibiotics or helping some patients with IBS — they are not a cure-all.

The effectiveness of probiotics depends on the strain, the dose, and the condition being treated. Randomly buying probiotics online may not help, and in some cases, they can worsen bloating or interact with medical conditions.

If you are considering probiotics, consult with Dr. Jack Husney, gastroenterologist in Brooklyn, who can guide you on whether they’re right for you and recommend evidence-based options.


Rectal Bleeding Is Always Hemorrhoids

Hemorrhoids are a common cause of rectal bleeding, but they are not the only one. Polyps, ulcers, inflammatory bowel disease, angiodysplasia, and colorectal cancer can also cause bleeding.

Assuming bleeding is “just hemorrhoids” can lead to delayed diagnosis of serious conditions. Any new, persistent, or unexplained rectal bleeding should be evaluated by a gastroenterologist. Often, this includes a colonoscopy, which allows for both diagnosis and treatment.

At our Brooklyn practice, Dr. Jack Husney stresses that early detection makes a major difference in outcomes, especially when it comes to colorectal cancer.

 

From heartburn remedies to colon cancer myths, misinformation can be dangerous when it comes to digestive health. If you’re struggling with reflux, abdominal pain, constipation, or rectal bleeding, don’t rely on internet “hacks.”

At our Brooklyn gastroenterology office, Dr. Jack Husney provides expert care including GERD treatment, colonoscopy, endoscopy, and management of IBS, hemorrhoids, and other GI concerns.
