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.

Monsoon Gut Health: Addressing The Rise In Rotavirus And Viral Gastroenteritis Cases

Updated Aug 8, 2026 | 11:00 PM IST

SummaryMonsoon conditions can increase the spread of rotavirus and viral gastroenteritis, making safe food, clean water, hand hygiene, and timely care important for preventing gut infections.

Every year, as the monsoon rolls in, hospitals and clinics across India see a familiar pattern: a sharp uptick in children and elderly patients presenting with vomiting, diarrhoea, and dehydration.

Doctors attribute this seasonal surge to a combination of contaminated water supplies, deteriorating food hygiene, and warm, humid conditions that favour the spread of viruses like rotavirus and norovirus.

Why Monsoon Fuels Gut Infections

Heavy rains and flooding routinely compromise municipal water lines, allowing sewage to mix with drinking water. Street food and produce are more prone to contamination during this period, and the humidity itself accelerates bacterial and viral growth.

Acute gastroenteritis, an inflammation of the stomach and intestines, is consistently one of the fastest rising monsoon health conditions, with rotavirus being a leading cause in children and norovirus a common culprit across age groups.

Understanding Rotavirus

Rotavirus is a highly contagious, wheel shaped virus and remains the leading cause of severe diarrhoeal illness and death in children under five worldwide. It spreads through the faecal oral route via contaminated water, food, surfaces, or close contact with an infected person, and can cause several days of intense vomiting and watery diarrhoea, putting young children at real risk of rapid dehydration.

The good news: Rotavirus vaccines, given orally in a series of doses before 8 months of age, are highly effective at preventing severe disease and are recommended as part of national immunisation programmes.

Expert Recommended Prevention Measures

1. Water safety first

Boil or filter all drinking water during the monsoon months. Avoid ice and beverages of uncertain origin, especially from street vendors.

2. Food hygiene

Steer clear of cut fruits, chaat, and other street food that has been sitting exposed. Cook food thoroughly and eat it hot. Avoid reheated leftovers stored without refrigeration.

3. Hand hygiene

Frequent handwashing with soap before eating, after using the toilet, and after changing diapers remains one of the single most effective, low cost interventions against faecal oral transmission.

4. Vaccination

Ensure infants complete their full rotavirus vaccine schedule on time. Vaccination substantially reduces hospitalisations and severe outcomes, even though it does not eliminate all seasonal transmission.

5. Isolate and disinfect

Because these viruses spread easily within households and childcare settings, keep infected individuals' utensils and linens separate, and disinfect surfaces regularly during an active infection.

Recognising The Warning Signs

Most cases of viral gastroenteritis are self limiting, but caregivers should watch for signs of dehydration that require urgent medical attention:

  • Sunken eyes, dry mouth, or reduced tears when crying (in infants)
  • Little or no urination for 6+ hours
  • Lethargy or unusual drowsiness
  • Persistent vomiting that prevents fluid intake
  • High fever or blood in the stool

Treatment: What Actually Helps

Oral Rehydration Solution (ORS) is the cornerstone of management.

A simple homemade version consists of 1 litre of boiled and cooled water, 6 teaspoons of sugar, and half a teaspoon of salt. It can be lifesaving when commercial ORS packets are not available, though pre mixed WHO formula ORS is preferable when accessible.

Zinc supplementation (around 20 mg daily for 10 to 14 days) is recommended for children under five, as it has been shown to reduce the duration and severity of diarrhoeal episodes.

Antibiotics are not effective against viral gastroenteritis and should only be used if a bacterial cause, such as cholera, is confirmed by a doctor. Inappropriate antibiotic use can do more harm than good.

Continue feeding. For breastfed infants, continue breastfeeding throughout the illness. For older children and adults, small, frequent sips of fluids and bland, easily digestible food are better tolerated than large meals.

When to See a Doctor

Seek medical care promptly if there is persistent high fever, visible blood in the stool or vomit, signs of moderate to severe dehydration, or if symptoms do not improve within 2 to 3 days, particularly in infants, the elderly, or anyone with underlying health conditions.

The Hidden Cost Of Self-Medicating UTIs. How Antibiotic Misuse Is Fueling Resistance

Updated Aug 8, 2026 | 09:00 PM IST

SummarySelf-medicating UTIs and misusing antibiotics can mask symptoms, delay proper treatment, and contribute to antibiotic resistance, making medical evaluation and appropriate prescribing essential.

Urinary tract infections are common. A lot of people get them every year. When you have a tract infection you might feel a burning sensation when you go to the bathroom you might have to go to the bathroom a lot and your lower belly might hurt. These symptoms can get in the way of your life. You might want to try to make the pain go away on your own. Taking medicine without prescription is not a good idea.

Taking antibiotics when you do not need them can be bad for you. Urinary tract infections can become harder to cure when the bacteria get used to the medicine. This is called resistance and it is a big problem for everyone’s health. When this happens, you might get tract infections repeatedly and you might have fewer choices, for treatment. That is why it is so important to go seek medical attention at the earliest.

Causes Of UTIs

Most Urinary Tract Infections are caused by bacteria that are usually in the digestive tract and then get into the urethra. Things like not having water, not keeping yourself clean having something wrong with the urinary system or having a weak immune system can make it more likely for bacteria to grow.

If you take the medicine or stop taking it too soon the strong bacteria will live and get stronger. Over time these bacteria will not be affected by the medicines, which makes them very hard to treat. This is what happens when you have a Urinary Tract Infection that is resistant to drugs. Urinary Tract Infections, like these are very tough to deal with.

Signs And Symptoms To Watch Out For:

Recognizing the early warning signs helps prevent the infection from spreading deeper into the body. Common signs of a UTI include:

  • A strong, continuous urge to urinate, even immediately after emptying the bladder
  • A burning or painful sensation during urination
  • Passing small amounts of cloudy, dark, or unusual-smelling urine
  • Visible blood in the urine, giving it a pink or reddish tint
  • Pelvic pain or pressure in the lower abdomen
  • Fever, chills, lower back pain, or nausea, which often signal that the infection has reached the kidneys

Tips For Prevention:

Preventing tract infections is always better than treating them especially now that we have a lot of antibiotic resistance. If you do simple things every day you can reduce the risk of bacteria getting into your urinary system.

Here are some things that can help:

1. Stay well hydrated: Drinking water is very important for urinary health. When you drink fluids during the day it helps wash away bacteria from the urinary system. This lowers the chance of getting an infection.

2. Prioritize good personal hygiene: Doing things to stay clean can help lower the chance of a UTI. It is best to wipe from front to back after going to the bathroom. This keeps bacteria from the stomach area from moving into the system.

3. Don’t delay urination: Going to the bathroom regularly helps stop bacteria from growing. If you hold your urine for long it can create a place where bacteria grow faster. This makes it more likely to get an infection.

4. Be cautious with intimate hygiene products: Products that have smells, like sprays or douches can hurt sensitive areas. They can also change the balance of bacteria that protect the body. This might make UTIs more likely.

5. Wear breathable fabrics: Choosing cotton underwear and clothes that're not tight helps keep the area dry. A dry and cool place is not a home, for bacteria. This lowers the chance of getting an infection.

Diagnosis And Proper Medical Evaluation

Accurate diagnosis is essential before starting any medication. Diagnosis start with an evaluation and a simple urine test called a urinalysis to check for bacteria white blood cells and red blood cells.

In cases a urine culture is also done. This test finds the strain of bacteria causing the infection and tests it against different medications to find out which antibiotic will work best. For people who have recurring UTIs imaging tests, like ultrasound or CT scans might be used to look at the structure of the urinary tract and find any blockages or problems that are there.

Treatment Options

Urinary tract infections or Urinary Tract Infections can usually be treated with antibiotics. You must take all the antibiotics even if you start to feel better so that you can be sure the Urinary Tract Infection is gone and you do not get sick again.

Medicines also help with the pain and discomfort you feel when you urinate, such as burning or feeling like you must go to the bathroom all the time.

In some cases, Urinary Tract Infections may recur due to underlying conditions such as kidney stones, urinary tract blockages, an enlarged prostate or structural abnormalities of the system. When these factors are identified, treating the root cause becomes essential.

Procedures such as kidney stone removal, stent placement or corrective surgery for urinary tract abnormalities may be recommended to prevent repeated Urinary Tract Infections.

Prevention and early intervention remain the effective strategies, in managing Urinary Tract Infections. Being aware of the warning signs and getting care at the onset of symptoms and avoiding unnecessary antibiotic use can significantly reduce the risk of recurrent Urinary Tract Infections and serious complications.

With diagnosis and appropriate treatment most Urinary Tract Infections can be successfully managed, safeguarding both urinary health and overall well-being.

Lung Health After 40: Natural Changes, Warning Signs And Ways To Protect Your Lungs

Updated Aug 8, 2026 | 07:00 PM IST

SummaryAfter 40, lung function naturally declines, making it important to recognise warning signs and protect lung health through exercise, avoiding pollutants, vaccinations, and regular check-ups.
Lung Health After 40: Natural Changes, Warning Signs And Ways To Protect Your Lungs

By the time we enter our 40s, the lungs begin to undergo gradual changes that can affect breathing capacity and respiratory reserve. While some changes are a normal part of ageing, persistent cough, breathlessness or recurrent chest infections should not simply be dismissed as getting older.

Experts explain why lung health deserves greater attention after 40, which everyday habits can help protect the lungs, and when screening or medical evaluation may be needed.

As we enter our 40s, what natural changes occur in our lungs, and why does lung health become more important at this stage of life?

As we age lung tissue elasticity declines and chest wall mechanics stiffen. From an oncology standpoint, age-related cellular damage and long-term exposure to cancer causing agents like tobacco increase cancer risk. Looking after lung health from young age builds the respiratory reserve needed to tolerate advanced medical or surgical interventions if required as you get older.

What everyday lifestyle habits can help keep our lungs healthy after 40?

Engage in regular aerobic conditioning exercises to maintain full breathing capacity. Reduce carcinogen exposure by avoiding active and passive tobacco smoke, and ensuring proper ventilation while cooking. using HEPA air purifiers may help to an extent. Maintain an antioxidant-rich diet to combat cellular oxidative stress.

What are some early signs of declining lung health that people often dismiss as 'just ageing' but should actually get checked?

2 to 3 week cut off is applicable here. A persistent cough lasting over three weeks, progressive exertional breathlessness, recurrent chest infections, coughing up blood, or unexplained weight loss are red flags. This is for both smokers and nonsmokers. Early-stage lung cancers are frequently asymptomatic or subtle; ignoring these signs delays diagnosis. These symptoms are that of TB as well. So, that should be ruled out.

Are there any health screenings, vaccinations, or routine check-ups that adults over 40 should consider to protect their lung health?

Annual flu and once in lifetime pneumococcal vaccine prevents severe pulmonary infections. For high-risk individuals—such as heavy past or present smokers—a annual Low-Dose CT (LDCT) scan is the gold standard for early lung cancer detection, finding lesions when they are most curable. Eliminating tobacco, mitigating indoor air pollution, exercising, and maintaining balanced nutrition significantly lower cancer risk and improve overall survival outcomes.
