Blood test flags digestive disease risk years before symptoms appear

A simple blood test may detect Crohn’s disease years before symptoms appear, according to a new study reported by SWNS.
Canadian researchers say the discovery could enable earlier diagnosis and potential prevention of the chronic inflammatory bowel disease (IBD).
The test measures the immune system’s response to flagellin, a protein found in gut bacteria. Researchers found that this response is elevated in some people years before Crohn’s develops.

The findings, published in Clinical Gastroenterology and Hepatology, highlight the “interplay” between gut bacteria and immune system responses as a key step in the disease’s development, per the SWNS report.
Crohn’s disease is a chronic inflammatory condition of the gastrointestinal tract that causes persistent digestive symptoms, pain and fatigue, significantly affecting quality of life. Its incidence among children has doubled since 1995, according to official figures.

The presence of flagellin antibodies long before symptoms appear suggests that the immune reaction may help trigger the disease, according to research leader Dr. Ken Croitoru, clinician-scientist and professor of medicine and immunology at the University of Toronto.
A better understanding of this early process could lead to improved prediction, prevention and treatment, the expert said.
“We haven’t cured anybody yet, and we need to do better.”
“With all the advanced biologic therapy we have today, patients’ responses are partial at best,” Croitoru told SWNS. “We haven’t cured anybody yet, and we need to do better.”

“We wanted to know: Do people who are at risk, who are healthy now, have these antibodies against flagellin?” he said. “We looked, we measured, and yes indeed, at least some of them did.”
This new research is part of the Genetic, Environmental and Microbial (GEM) Project, which has followed more than 5,000 healthy first-degree relatives of people with Crohn’s disease worldwide since 2008. The project collects genetic, biological and environmental data to better understand how the disease develops.

The study followed 381 first-degree relatives of Crohn’s patients, 77 of whom later developed the disease. Of those, more than 30% had elevated antibody responses.
The responses were strongest in siblings, underscoring the role of shared environmental exposure, researchers said.

So far, 130 of the study participants have developed Crohn’s, giving researchers a rare opportunity to study its earliest stages. The average time from blood sample collection to diagnosis was nearly 2-½ years.

Previous GEM research showed that an inflammatory immune response targeting gut bacteria can appear long before the disease develops.

In healthy people, gut bacteria coexist peacefully and play an essential role in digestive health — but in Crohn’s patients, the immune system appears to mount an abnormal response against the microbes, experts say.

The Canadian team also confirmed that this pre-disease immune response was associated with intestinal inflammation and gut barrier dysfunction, both hallmarks of Crohn’s disease.
The study did have some limitations, including that it did not include experiments to show exactly how the immune response might lead to Crohn’s disease. (iStock)
Research team member Dr. Sun-Ho Lee, a gastroenterologist, commented that this new study supports the idea of designing a flagellin-directed vaccine for certain high-risk individuals to prevent the disease, according to SWNS.

The study did have some limitations, including that it did not include experiments to show exactly how the immune response might lead to Crohn’s disease.
As a result, the researchers could not determine the biological steps linking the immune reaction to the onset of the illness. “Further validation and mechanistic studies are underway,” they noted.

As the popularity of GLP-1 drugs continues to climb, significant weight loss associated with the medications has been linked to a growing list of cosmetic concerns.
Some surgeons report that more patients are seeking treatments for so-called “Ozempic earlobes,” which reportedly appear thinner, longer or more sagging after the loss of facial fat.
“The use of semaglutides causes you to lose fat across your body, including the small, fat pads of the earlobes,” facial plastic surgeon Sachin S. Parikh, MD, told NewBeauty.
OZEMPIC, OTHER SEMAGLUTIDES LINKED TO HAIR LOSS: HERE’S WHAT TO KNOW
“It’s important to note that semaglutides do not damage ear tissue or affect hearing in any way, so any intervention would be purely cosmetic,” added the California-based doctor.
Some of the potential treatments for “Ozempic earlobes” may include dermal filler, fat transfer, laser treatments or surgical earlobe reduction, according to the report.

Dr. Mohammed Asif from Duly Health and Care in Naperville, Illinois, said that while he hasn’t personally noticed an uptick in ear surgeries, he has seen a rise in other procedures due to GLP-1-triggered weight loss.
Some of those include panniculectomies (Ozempic skin removal surgery) and abdominoplasties (tummy tucks).
PLASTIC SURGERY TRENDS TAKE A SURPRISING TURN, AS DOCTORS SEE MORE PATIENTS ‘SIZING DOWN’
“There has been a significant increase in body contouring procedures among patients with GLP-1 weight loss,” Asif told Fox News Digital.
“In my practice, I’ve seen a significant surge in breast lifts, panniculectomies (skin removal surgery), abdominoplasties (tummy tucks), brachioplasties (arm lifts) and thighplasties due to weight loss.”
TOP COSMETIC PROCEDURES REVEALED IN NEW REPORT: WHAT’S TRENDING AND WHY
Healing and recovery are “far greater and less complicated” than with bariatric surgery weight loss, Asif noted.
“This is due to the gradual weight loss achieved over time with GLP-1s.”
“Ozempic breast” is another common complaint, according to Dr. Michael Omidi, a double board-certified plastic surgeon practicing in Beverly Hills.

“Women in their 30s and 40s would not typically need a breast lift, but when you’re taking drugs like Ozempic or Wegovy that cause rapid weight loss, women can see gravity take its toll on their breasts,” he told Fox News Digital.
“When women, especially younger ones, lose fat too fast, it causes the breasts, which are comprised of fat, glandular tissue and skin, to lose volume,” he went on. “The skin and supporting ligaments don’t always bouce back at the same rate as the weight loss, resulting in breasts that can appear saggy and deflated.”
NEW OBESITY TREATMENT MAY HELP PRESERVE MUSCLE DURING WEIGHT LOSS
Dr. Samuel Golpanian, a double board-certified plastic surgeon in Beverly Hills, said he has seen “dozens” of patients – men and women alike – seeking treatments for so-called “Ozempic butt” after significant weight loss.
“This is an unintended consequence of taking GLP-1s,” he told Fox News Digital.

“Such dramatic weight loss in a short period of time causes the skin not to tighten quickly enough to keep up with the body’s changes. Our buttocks have a large amount of fat, so when that volume disappears quickly, you’ll develop a flatter, saggier behind.”

Kristy Hamilton, MD, a Houston-based surgeon who is a member of the American Society of Plastic Surgeons (ASPS), agreed that a growing number of patients are seeking skin-tightening procedures after losing large amounts of weight with GLP-1s.
“We’re absolutely seeing more of those patients, and I expect that trend to continue,” said Hamilton in an ASPS report.

“People are losing as much as 100 pounds on this medication – and when you’re losing that amount, that’s significant. You’re certainly going to have excess skin afterward.”
The ASPS lists the following body-contouring procedures as the ones most frequently performed after substantial weight loss.

- Tummy tuck (abdominoplasty): Removes excess abdominal skin and fat
- Lower body lift (belt lipectomy): Addresses the abdomen, buttocks, hips and thighs
- Arm lift (brachioplasty): Removes hanging upper-arm skin
- Thigh lift: Tightens excess skin of the inner thighs
- Breast lift (mastopexy): Addresses sagging, deflated breasts after weight loss
- Facelift/neck lift: Addresses facial volume loss and skin laxity after major weight loss

Experts say adequate protein intake and resistance training can help minimize the loss of lean muscle mass that often accompanies rapid weight loss, which could reduce some of the cosmetic concerns.
Golpanian also emphasized the importance of eating enough protein.

“It can be harder since your appetite is suppressed, but it’s so important to consume at least 110 grams of protein a day while taking a GLP-1 drug,” he advised.
“Also, I say this to my patients all the time: You have to lift weights to keep your muscles from atrophying. Strength training can help build muscles and preserve your glutes.”
