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.

How Genetic and Genomic Testing Can Help Women Make Smarter Cancer Decisions

Updated Aug 21, 2026 | 07:30 AM IST

SummaryGenetic testing is usually performed on blood or saliva to look for inherited changes or genetic predisposition. Genomic testing is usually performed on tumor or blood samples to identify molecular features, enabling a better understanding of the tumor's biology and biomarkers.

Being aware of personal and family cancer risk may be a critical component in women's knowledge and empowerment to make appropriate screening, prevention and treatment decisions.

Cancer treatment is fast evolving. Doctors are now focusing more on the person than the location or type of cancer and are considering the personal attributes of the patient and the disease. Genetic/genomic testing can complement this and can offer something more that could inform personalised cancer care.

Genetic testing: Knowing your inherited risk

Genetic testing screens for changes in the genes that could be passed down from parents. Some genetic mutations passed down from parents can make a woman more likely to get breast or ovarian cancer.

Having such a genetic change does not mean that a woman will develop cancer. This information will help her and her doctor discuss screening, monitoring and preventive action (if applicable) to reduce her risk.

This information may be useful for family members who could be at risk and should talk to their health care provider about their own risk.

Genomic testing: Understanding the cancer better

There is a difference between genetic testing and genomic testing. Genetic testing is usually performed on blood or saliva to look for inherited changes or genetic predisposition. Genomic testing is usually performed on the tumour or blood to identify its molecular features to enable better understanding of its biology and biomarkers.

Cancer is not one disease and even two patients with the same type of cancer can have different biological characteristics, which can help doctors decide on the treatment and options that may be suitable for an individual patient.

Genomic testing could help to pinpoint features of a tumour that can be used to consider particular targeted treatments or other methods. But not all of them will be suitable or available to all patients based on the results of testing.

Why Awareness About Health Issues Is Important

For women, knowing their family history and discussing any concerns with a doctor can be an important starting point. Genetic or genomic testing should not be done simply because it is available. A specialist may recommend testing based on factors such as family history, age at diagnosis and the type of cancer involved.

It is also important to understand test results correctly. Genetic counselling and discussions with an oncology specialist can help women understand what their results mean and what they do not mean.

Ultimately, genetic and genomic testing is not about predicting the future with certainty. It is about giving patients and doctors more information to make better-informed decisions.

As cancer care moves towards greater personalisation, the freedom to know your risk can become a powerful part of taking control of your health—helping women move from fear and uncertainty towards awareness, informed choices and personalised care.

World Mosquito Day, observed on August 20, raises awareness about mosquito-borne diseases such as dengue, malaria, Zika, yellow fever, and chikungunya and the health risks they pose.

Among these diseases, dengue remains a major public health concern, affecting people across regions worldwide throughout the year.

Dengue Cases: The Latest Numbers

  • Global: More than 1.5 million dengue cases and over 500 dengue-related deaths have been reported globally since the beginning of 2026, as of July 31.
  • Americas: 1,373,756 cases had been reported as of epidemiological week 26, updated July 23. Of these, 28.9% were laboratory-confirmed, according to WHO PAHO.
  • South-East Asia: WHO SEARO bulletins published in June and July reported dengue in Bangladesh, Bhutan, India, Maldives, Myanmar, Nepal, Sri Lanka, Thailand, and Timor-Leste since July 2025.
  • India: 22,938 cases had been reported in 2026 as of June. June recorded 6,625 cases, up from 3,747 in May — a 77% increase.

Why Can Dengue Affect the Kidneys?

Dengue is typically associated with high fever, joint pain, and low platelet counts. However, severe dengue can affect the kidneys and lead to acute kidney injury (AKI).

Speaking to HealthandMe, nephrologists said kidney problems may not always cause symptoms early on, making monitoring particularly important in severe dengue.

Dr. Anupam Roy, Additional Director - Nephrology and Kidney Transplant, Aakash Healthcare Multi-Speciality Hospital, Dwarka, said that recovering from dengue requires careful fluid management, particularly in severe cases.

It is because the kidneys regulate fluids and electrolytes, and changes in circulation caused by dengue can temporarily disrupt their function.

Fever, vomiting, and poor fluid intake can cause dehydration, while severe dengue can cause plasma leakage. Both too little and too much fluid can create problems, making medical supervision important. In hospital, healthcare professionals monitor urine output and signs of dehydration, particularly in patients with complications or underlying health conditions.

After the acute phase, patients should gradually resume eating and drinking according to medical advice. Excessive fluid intake and self-medication should be avoided, particularly when medicines could place additional stress on the kidneys.

“So, it is the quantity issue that must be tackled,” Dr. Roy said.

Signs of Kidney Problems

According to Dr. Manoj Arora, Consultant Nephrologist, NephroPlus, a network of dialysis centers, warning signs include:

  • Decreased urination
  • Swelling of the face or legs
  • Dark or foamy urine
  • Increased blood pressure
  • Unusual tiredness
  • Nausea
  • Breathing problems
Tea-colored urine may be concerning for rhabdomyolysis, in which muscle breakdown releases substances that can injure the kidneys.

Some symptoms can overlap with severe dengue, including continuous vomiting, severe stomach pain, and bleeding.

Who Is at Higher Risk?

Kidney injury is more likely in people with severe dengue or shock. Older people and those with diabetes, hypertension, obesity, or existing kidney problems may also face higher risk.

Seek medical attention for a drastic reduction in urine, new swelling, blood in the urine, worsening breathlessness, confusion, or continuous vomiting.

In hospitalized patients, monitoring is important when creatinine rises, electrolyte levels fluctuate — particularly potassium — or urine output continues to change.

How Can Kidney Damage Be Prevented?

Early recognition and appropriate management are key. Doctors may monitor:

  • Fluid balance
  • Urine output
  • Kidney function
  • Electrolyte levels
  • Potentially harmful medications

Do not self-medicate or increase fluid intake without medical advice, particularly during severe dengue.

How to Reduce Your Risk of Dengue

Reducing mosquito exposure and preventing mosquito breeding can help lower the risk of dengue.

  • Eliminate stagnant water
  • Use mosquito repellents
  • Use bed nets
  • Keep mosquitoes out
  • Wear protective clothing
  • Check your surroundings regularly.

Ever Wonder Why You Keep Scrolling Short Videos? Your Brain May Be Switching Off Self-Control

Are you someone who can spend hours scrolling through short videos on Instagram, YouTube or TikTok? A new study suggests that watching preferred short videos may temporarily quiet brain regions involved in self-control and monitoring, offering a possible clue to why it can be so hard to stop.

Short Videos May Quiet Brain’s Self-Control Network

The research, published in the journal NeuroImage, found that watching preferred short videos may temporarily suppress activity in parts of the brain involved in cognitive control. This effect may also be linked to levels of the brain chemical glutamate.

The study focused on the dorsal anterior cingulate cortex (dACC) and dorsolateral prefrontal cortex (dlPFC). Both are key regions of the cognitive control network, which becomes active during tasks that require mental effort, attention and self-regulation.

Researchers from Zhejiang University in China found that both the dACC and dlPFC showed significant deactivation when participants watched preferred videos to completion, compared with less-preferred videos that were stopped early.

The liked videos significantly reduced activity in both brain regions linked to cognitive control. When participants watched videos they chose to continue, activity in the dACC and dlPFC fell below normal resting levels.

However, disliked videos showed a different pattern. Activity in the dACC remained close to normal, while the dlPFC was still suppressed. Meanwhile, the visual cortex remained active during both types of videos, suggesting the changes were linked to the viewing experience rather than simply looking at a screen.

Glutamate May Influence How The Brain Responds

The small study of 56 participants also examined whether resting levels of two important brain chemicals could help explain differences in how participants’ cognitive control networks responded during short-video viewing.

Glutamate is the brain’s main excitatory neurotransmitter, helping increase neural activity. Gamma-aminobutyric acid (GABA) is the brain’s main inhibitory neurotransmitter, helping reduce or regulate neural activity.

The researchers found that resting-state glutamate levels in the dACC were associated with the extent of brain deactivation. Higher glutamate concentrations were linked to less suppression of activity in both the dACC and dlPFC.

Functional connectivity between the dACC and dlPFC also increased during video viewing, particularly when participants watched their preferred videos.

How Immersive Viewing Affects Brain

The researchers said the findings provide new evidence that immersive viewing of preferred short videos can deactivate the cognitive control network and that individual differences in this response may be linked to glutamate metabolism.

They suggested that the findings could help improve understanding of how digital media consumption interacts with neurochemical processes involved in self-regulation and may offer insights into the neural mechanisms behind excessive short-video use.

The study, however. does not establish that short-video viewing directly causes a loss of self-control or addictive behavior.

Why Excessive Short-Video Maybe Harmful?

Previous research has linked excessive short-video use with changes in attention, focus and mental well-being.

Studies in Nature Communications and research from the American Psychological Association suggest that highly stimulating, rapidly changing content may encourage constant novelty-seeking and make sustained attention more difficult.

Potential effects include:

  • Reward-seeking behavior
  • Reduced attention span
  • Mental fatigue
  • Sleep disruption
  • Emotional reactivity
Research in JAMA Pediatrics has also linked heavy screen use among adolescents with attention difficulties and lower well-being, although effects vary based on screen time, content and usage patterns.

Short videos are not inherently harmful, but excessive or compulsive scrolling can become a concern when it interferes with sleep, work, studies or daily life.
