A Blood Test For Irritable Bowel Syndrome Can Help Build A Better Diet

Updated Feb 28, 2025 | 02:00 AM IST

SummaryAllergies, food intolerances and many other conditions often restrict people to a certain diet. Often people try some foods to realize whether they can eat it or not and that can cause harm or discomfort to them even if it isn’t long term. But a new test may resolve the trial and removal method all together!

Diet plays a very important role when it comes to your health. There are many people who have to adhere to strict diets because of certain conditions they have. While the basic understanding that we need all kinds of foods to fulfill our body’s needs, sometimes these foods can also cause harm to your body. For example, lactose intolerant people cannot eat or consume any kind of dairy product as their bodies do not have the necessary compounds, known as lactose, to break down dairy foods. Similarly, there are many foods that may be ok for others to consume, but not for people who have digestive issues like IBS. But this new clinical trial may be able to help us know what food we can eat based on our blood test! The blood test, called inFoods IBS, looks for a special type of antibody in the blood. Antibodies are like tiny soldiers that our bodies make to fight off things that could make us sick.

IBS is a very common problem, affecting a large number of people. Many people know that what they eat can make their IBS symptoms worse, but it's often hard to figure out exactly which foods are the culprits. This is because everyone is different, and what triggers one person might not trigger another. Doctors hear from patients all the time, asking for help in determining which foods are causing their problems. So, finding a reliable way to pinpoint those foods is important. This test is attempting to provide that reliability.

How Does This Blood Test Work?

Basically, the test is looking for an antibody called IgG. When the gut reacts badly to a food, it makes more of this IgG antibody. The test checks for reactions to 18 common foods, like wheat, milk, and certain fruits. If the test finds high levels of the IgG antibody for a certain food, it means that food is likely causing problems. Therefore, the patient should try to remove that food from their diet.

Many people with IBS struggle to find relief from their stomach pain and discomfort. This new study looked at whether a special blood test could help. The idea was to see if the test could tell people which foods were making their IBS worse. The results were encouraging. When people changed their diets based on what the blood test showed, about 60% of them felt less stomach pain. This is better than the 42% who felt better when they just tried a general diet change. This shows that the blood test might be a useful tool for people with IBS to get real relief.

How Does This Personalized Nutrition Approach Work?

Many doctors suggest that people with IBS try elimination diets, where they cut out certain foods to see if their symptoms improve. However, these diets can be very hard to follow, because they often require people to cut out a lot of different foods. Doctors are always looking for ways to give patients care that's tailored to their specific needs. In the case of IBS, that means figuring out exactly which foods each person should avoid.

This blood test is a step in that direction. Experts are calling it a move towards "precision nutrition." This means that instead of giving everyone the same diet advice, doctors could use the blood test to create a personalized plan for each patient. While more research is needed, this test brings hope that doctors will soon be able to give much more precise dietary recommendations to those people that suffer from IBS. While this test is yet to be approved by FDA, it could be a world of comfort and ease for people who suffer with IBS.

New AI Tool Uses Facial Photos To Predict Cancer Patients’ Survival Risk

Updated Oct 21, 2026 | 04:00 PM IST

SummaryResearchers at Mass General Brigham have developed AI tools that analyse facial photographs to estimate biological age and predict short-term mortality risk among cancer patients. Published in The Lancet Digital Health, the findings show promise but require further validation before clinical use.

A single photograph of someone’s face might carry real clues about their health and how long they’re likely to live, at least according to new AI tools built by researchers at Mass General Brigham in Boston.

What the researchers built

The team trained a large AI foundation model called FAHR-Face, short for Foundation Artificial Intelligence for Health Recognition, on more than 40 million facial images.

From that base model, they built two specialised tools: FAHR-FaceAge, which estimates a person’s biological age from a single photo, and FAHR-FaceSurvival, fine-tuned on 34,389 photos of cancer patients to predict survival risk directly from facial appearance.

“I was pretty surprised to find out that we could pick up signs of mortality risk from just a facial photograph,” corresponding author is Dr. Raymond Mak, a radiation oncologist at Mass General Brigham Cancer Institute told CNN. The study is published in The Lancet Digital Health.

What the two tools actually look at

The two algorithms focus on entirely different parts of the face. “The age estimation algorithm is looking at the area around the temples, the area on the forehead, above the eyes and then what we call the nasolabial fold,” Mak said, while “the mortality risk prediction algorithm is looking at a totally different part of the face... the bridge of the nose and the area under the eyes.”

The results

Among 122 cancer patients flagged by FAHR-FaceSurvival as high-risk, 52.5% died within 90 days, compared with about 2% of the 975 patients in the lowest-risk group. Separately, 21% of patients whose biological age came back more than 20 years older than their actual age died within 90 days, against about 6% of those whose biological age was at least 10 years younger than their chronological age.

The researchers also found that cosmetic changes, including surgery, Botox, or makeup, didn’t throw off the models’ performance, according to the Mass General Brigham release.

An eerie echo of ancient medicine

The facial regions both AI models rely on, the nose, temples, and the area around the eyes, closely match what the Greek physician Hippocrates described around 400 BC in his Book of Prognostics as signs of approaching death: “the nose sharp, the eyes sunken, the temples fallen in.”

Mak told CNN the algorithms had no exposure to Hippocrates’ text and were trained purely on photographs and outcomes data. “Hearing Hippocrates echo over millennia in our algorithms was very eerie,” he said.

Not ready for the clinic yet

Outside experts urged caution. Dr. Wilbur Lam of Emory University, who wasn’t involved in the study, called it “an extremely compelling study” with robust associations, but said its “true clinical utility... will need to be demonstrated prospectively,” and flagged open questions about how well it performs across different facial features, skin tones, and age groups.

Miroslaw Bober of the University of Surrey, also not involved in the study, said the findings shows “convincing evidence” of a statistical link but cautioned that “predicting an outcome is not the same as explaining it.”

He noted the study never tested whether the AI model picks up anything a doctor’s own assessment wouldn’t, since doctors’ general health evaluations weren’t measured for comparison. “This is a promising proof of concept, but it is not ready for clinical use,” Bober said.

WHO's Health Inequality Report Shows How Income, Education And Gender Influence Noncommunicable Diseases Risk

Updated Oct 21, 2026 | 02:00 PM IST

SummaryWHO released its first global assessment in health inequality through the report titled 'State of Inequality: Noncommunicable Diseases and Their Risk Factors'. It detailed major geographical, economical and lifestyle factors that affect the risk of NCDs.

An individual's income, education, gender and place of residence can impact their risk of developing chronic diseases, as well as their access to diagnosis and treatment, according to a new World Health Organization (WHO) report.

The report highlights how social and economic inequalities affect the burden of noncommunicable diseases (NCDs) like cancer, cardiovascular diseases, diabetes and chronic respiratory diseases.

Published on October 20, State of Inequality: Noncommunicable Diseases and Their Risk Factors is WHO's first comprehensive global assessment of inequalities in NCDs and their risk factors. The report is based on data sources from nine countries and examines 35 indicators, using national data that collected over the past decade.

NCDs account for about three-quarters of deaths worldwide but their impact is not shared equally across different countries and their populations. The report examines how differences in economic status, education, sex, age, disability, employment, migration status and location influence disease risks and access to healthcare.

“This is the first effort to systematically measure inequalities in NCDs and their risk factors on a global scale,” said Dr Ahmad Reza Hosseinpoor, who leads WHO's health inequality monitoring team. “The findings show which populations are being left behind.”

How Income And Education Influence Chronic Disease Risk

The report found that people with lower levels of education in low and middle income countries tend to have higher rates of hypertension and diabetes.

Education can affect access to credible health information, opportunities to make informed health decisions and the capability to navigate technically complex healthcare services.

Income becomes a key factor that affects whether people's ability to afford nutritious food, preventive care, medicines and routine medical check-ups.

The report found that the poorest and least-educated women were less likely to receive cervical cancer screening. Tobacco use was also higher among men who were less educated than their educated counterparts.

Risk Is Also Affected By Gender And Location

Differences in healthcare access and risks were also observed between men and women. Men were more likely to use tobacco and consume alcohol, but men with hypertension were less likely to be diagnosed and treated than women.

Women were less likely to meet recommended physical activity levels, while obesity was more common among women, particularly in low and middle-income countries.

Geography was another key factor as in many underprivileged countries, people living in rural areas had less access to hypertension diagnosis and treatment, as well as cervical cancer screening.

Rural households could also face greater exposure to household air pollution, while urban populations often experienced greater exposure to outdoor air pollution.

People with disabilities and migrants may also face financial, administrative, geographical or language barriers that make prevention, screening and treatment harder to access.

What Needs To Change According To WHO

WHO said countries should use inequality data to identify marginalised populations who face barriers to enable direct prevention and treatment services towards them.

The report recommends expanding interventions to reduce NCD risks, improving access to screening and treatment in weak communities, and collecting data that reveal differences between population groups.

“Inequality data are not simply about documenting differences – they are a tool for action,” said Dr Alain Labrique, director of WHO's Data, Digital Health, Analytics and AI Department. “They help countries better tailor policies and programmes, identify gaps in coverage and track whether progress is reaching all population groups.”

ADHD Linked To 71% Higher Risk Of Death; Suicide And Injuries Among Top Concerns

Updated Oct 21, 2026 | 09:16 AM IST

SummaryA recent study in 'Jama Network Open' observed that people diagnosed with ADHD are at higher risk of death from natural causes, accidents, and suicides.

People diagnosed with attention-deficit/hyperactivity disorder (ADHD) had a 71% higher rate of death from any cause than those without the condition, new review published in JAMA Network Open states. The findings highlight health risks that extend beyond ADHD's core symptoms.

The study also found higher rates of death by suicide and injuries. ADHD medication, on the other hand, was reported to cause overall lower mortality.

Researchers from University College London (UCL) and the University of Liverpool reviewed 19 observational studies involving nearly 16 million people across three continents.

Suicide And Injuries Among Key Concerns

The review found that people with ADHD had an 89% higher rate of death by suicide and a 55% higher rate of death from intentional or unintentional injuries, compared to people without ADHD.

Deaths from natural causes, including those related to physical health conditions, were also 27% higher.

Researchers said several factors could contribute to these findings. People with ADHD may experience difficulties with impulse control and emotional regulation, as well as higher rates of other mental health conditions. Challenges with attention may also contribute to accidental injuries, including road accidents.

Physical health risks due to lifestyle may play a role too. Smoking, alcohol use, substance abuse and accessing healthcare could affect these results.

Senior author Professor Joshua Stott of UCL said, “We found that people with ADHD face an increased risk not only of death by suicide and injury, but also of deaths by natural causes, adding to evidence that health inequalities faced by people with ADHD are broad and wide-ranging.”

ADHD Medication Linked With Lower Mortality

The review found that people with ADHD who took prescribed medication had a 25% lower risk of death from any cause than those who did not take medication.

However, this finding was based on only three of the 19 studies included in the review. The researchers said that more research is needed to understand whether medication directly reduces mortality risk.

First author Lucy Corrigan of the University of Liverpool said, “Our findings provide early evidence to suggest that medication may play an important role in supporting the health of people with ADHD, but this is based on a small number of studies and further research is needed to clarify this link. And medication is just part of the story; many people with ADHD benefit from comprehensive, long-term treatment and support.”

More Investigation Needed

The researchers said that all the studies included in the review were observational. This means the results show associations and cannot establish that ADHD itself causes early death or that medication prevents it. The studies also differed in their methods and in the size of the risks they reported.

Stott said, “ADHD is not by definition a life-limiting condition as the right support and treatment can help people with ADHD to live long and healthy lives. Our findings underscore the importance of ensuring that everyone who may have ADHD has access to accurate diagnosis and treatment. While ADHD diagnosis rates have risen in recent years, they may still lag behind actual prevalence, particularly for older age groups where mortality risk may be most pertinent.”
