How Old Are Your Organs? New Study Links Organ Aging to Disease Risk

Updated Mar 19, 2025 | 05:00 PM IST

SummaryThe blood plasma samples were collected between 1997 and 1999 from participants between ages 45 to 69. Researchers have now examined a follow up data from 6,235 participants, who were by then aged 65 to 89. This was done to see how aging of specific organ may correlate with the development of diseases over two decades.

A new study published in The Lancet Digital Health suggests that biological age of different organs could predict a person's risk of diseases such as cancer, dementia, and heart disease than their actual chronological age. The research analyzed long-term data from Whitehall II study, which had been followed by over 10,000 British adults for more than 35 years.

The blood plasma samples were collected between 1997 and 1999 from participants between ages 45 to 69. Researchers have now examined a follow up data from 6,235 participants, who were by then aged 65 to 89. This was done to see how aging of specific organ may correlate with the development of diseases over two decades.

What Organs Were Studied?

The study measured the biological age of nine key organs, including:

  • Heart
  • Blood vessels
  • Liver
  • Immune system
  • Pancreas
  • Kidneys
  • Lungs
  • Intestines
  • Brain

The researchers were able to find that different organs aged at different rates in different people. In many of the cases multiple organs showed signs of faster aging within the same individual. What is important to note is that those with accelerated aging in certain organs had a higher risk of developing 30 out of the 40 age-related diseases the study had tracked.

Organ Aging And Disease Risk

Some organ-disease connections were expected—people with rapidly aging lungs were more likely to develop respiratory diseases, and those with aging kidneys had an increased risk of kidney-related conditions. However, the study also found less obvious associations.

For example, individuals with fast-aging kidneys were more prone to diseases in other organs, such as the liver and pancreas. Additionally, multiple fast-aging organs were linked to an increased risk of kidney disease.

One of the most surprising findings was that dementia risk was not best predicted by an aging brain but rather by the immune system’s biological age. This suggests that factors such as chronic inflammation and immune health may play a critical role in neurodegenerative diseases.

What Is Organ Specific Blood Tests?

The study also highlights the important of the potential of developing blood tests that could assess the biological age of specific organs. Unlike previous complex methods that measured the organ health, this new approach could make things simple to detect early signs of disease.

The leader author of the study Mika Kivimaki, who is also a professor at the University College London's Faculty of Brain sciences pointed out that such tests could be helpful when it comes to guiding personalized healthcare. In a news release, Kivimaki said, "They could advise whether a person needs to take better care of a particular organ and potentially provide an early warning signal that they may be at risk of a particular disease."

The study reinforces the idea that aging does not affect all organs equally and that looking beyond chronological age could offer better insights into disease prevention. By understanding which organs are aging more rapidly, medical professionals may be able to recommend targeted interventions for individuals at higher risk of specific conditions. Future advancements in organ-specific blood testing could revolutionize how we detect and manage age-related diseases, potentially leading to more personalized healthcare strategies.

Teachers are unarguably one of the most important influences during the early stages of a person's life. Along with learning and wisdom, teachers can also influence a child's or adolescent's mental health. Thus, they help shape students who are the future of any society or nation. This impactful profession and its contributions are celebrated worldwide, including in India.

The deteriorating mental health condition in students has escalated into a major global public health concern, heavily accelerated by academic pressure, systemic changes, and digital isolation. The World Health Organization (WHO), UNICEF, and Indian governmental bodies like NCERT have shared data that reveals a grim situation: there is a huge gap between the rising psychological distress among youth and the infrastructure available to support them.

The role of teachers in youth mental health is a topic that the study "A Shelter for the Heart: The Impact of Teacher Quality on Students' Mental Health" has thoroughly analyzed. The research, published in the journal Health Economics in 2026, was conducted in China and included 3,529 Grade 7 students, 86 classrooms, and 43 schools throughout the country. The study examines the impact of teacher quality, proxied by teacher experience, on student mental health.

How Do Teachers Protect Students' Mental Health?

According to the study, the role of the head teacher is particularly important to a student's mental well-being. While subject teachers are primarily responsible for learning, the study emphasizes that experienced teachers might do more than improve grades—they may also help protect students' mental health.

The study finds that the more experienced head teachers tended to build stronger teacher–student relationships, communicate more with parents, and create more supportive classroom environments. They were less likely to ignore or isolate struggling students and more likely to try to help them. All in all, the researchers concluded that school environments play an important role in determining adolescents’ mental health.

Mental Health On Location And Gender

The study “A study on mental health of students teacher in relation to their achievement in education psychology” by researchers at Tamil Nadu Teachers Education University, Chennai, found significant differences in mental health based on gender and location, with female and rural student-teachers reporting better mental health than their male and urban counterparts.

Teacher Distress Linked To Student Mental Health

A 2024 study published in BMC Psychology by researchers from McMaster University, the University of Sydney, the University of Johannesburg and the Hospital for Sick Children examined the relationship between teacher distress and student mental health. The researchers analysed data from 23,568 students and 1,478 teachers across 268 schools in Ontario, Canada. The researchers suggested that supporting teachers’ mental health and creating safer school environments could also benefit students’ well-being.

A 2019 study published in the Journal of Affective Disorders by researchers led by Stephen Harding also suggested that better teacher well-being was associated with better student well-being, highlighting the potential importance of supporting teachers’ mental health within schools.

Teachers Day 2026

Teachers’ Day 2026 in India is celebrated on September 5 to honour the contribution of teachers and educators. The day marks the birth anniversary of Dr. Sarvepalli Radhakrishnan, India’s first Vice President and second President, who was a distinguished philosopher, scholar and teacher. Since 1962, his birthday has been observed as Teachers’ Day in India. The occasion recognises teachers’ role in shaping students’ knowledge, character, confidence and well-being, while inspiring future generations to learn, grow and contribute to society.

5 Important Differences Between Living And Deceased Organ Donation

Updated Sep 5, 2026 | 09:00 AM IST

SummaryDeceased organ donation can help bridge India’s severe organ shortage, while live donation offers another vital transplant pathway, each with distinct processes, possibilities, and limitations.

Deceased organ donation covers our organ needs. In India, we are woefully short of organs such as kidneys and livers in cases of liver and kidney failure that need to be transplanted.

Deceased donation, as the name sounds, is a donation by people who are brain dead, whose family has now accepted and has willingly donated their organs for the benefit of the rest of the world.

Live donation, on the other hand, is a donation by living or emotionally related individuals who want to donate a kidney to a diseased patient. A live donation is usually transplanted immediately. It's done in the same centre, and both are done together, as the harvesting of the organ from the donor and transplantation are done simultaneously.

On the other hand, a deceased organ from a cadaveric donor may be harvested in a different geographical location and may be transported over time and over a lot of distance to another centre.

Deceased donation can be done for organs that cannot be transplanted by live donation, which are so consequential to a human body, such as the heart, lungs, and pancreas. They are very vital and cannot be transplanted from a live patient to another.

In a deceased organ donation, we can even donate tissues such as the cornea, skin, and blood vessels, which are required as a part of donation, as a part of other organ donation transplant programmes or, for example, in giving vision to people who have a white cornea or corneal opacity.

These are a few differences between live and deceased or cadaveric donation.

Fibroid Or Rare Cancer? When Common Symptoms Need A Second Opinion

Updated Sep 4, 2026 | 08:00 PM IST

SummaryUterine fibroids are common and benign, but their symptoms can resemble rare uterine sarcoma, highlighting why accurate diagnosis, MRI, monitoring, and second opinions matter.

A uterine growth diagnosis can be very alarming. That said, it is vital to note that such growths are often simple, run-of-the-mill fibroids. They are non-cancerous, very common, and completely harmless. At the same time, it is important to realise what uterine sarcoma is, and why fibroids are often confused with uterine sarcoma. It comes down to anatomy. The uterus consists mainly of smooth muscle tissue. A fibroid is just an overgrowth of this smooth muscle that expands over time. Uterine sarcoma is a rare cancer that originates within that very same muscle wall. Since both develop in the same spot, they tend to trigger identical symptoms—like unexpected bleeding, pelvic aching, or pressure.

Why Accurate Diagnosis Matters Before Surgery

Before starting treatment, it is important to fully understand what the diagnosis is, as that is the first step to safety.

Surgeons often treat routine fibroids with minimally invasive techniques. These methods break or chop the tissue into smaller fragments so it can be pulled through tiny incisions. If a growth, however, turns out to be an unsuspected sarcoma, breaking it apart inside the pelvis can spread malignant cells. A thorough diagnostic workup beforehand makes sure nothing gets disrupted accidentally, so that the surgical team builds the safest possible treatment plan.

What You Need to Know About Fibroids

Here is some genuine peace of mind: benign fibroids don't suddenly turn into cancer. Medical research shows that malignant transformation inside an existing fibroid is exceptionally rare. Because fibroids and sarcomas are biologically different conditions from the start, monitoring a standard fibroid does not put you at risk of it turning into a tumor down the line.

Most fibroids stay completely harmless throughout life. It is, however, important to watch out for a few specific red flags:

Post-menopause changes: Fibroids shrink on their own once hormone levels drop after menopause. Any new growth or spotting at this stage demands a closer look.

Growths that keep expanding on medication: If a mass gets bigger while one is on prescriptions designed to shrink it, the patient must seek out a secondary review.

Ambiguous scans: When a routine ultrasound shows atypical tissue structure, stepping up to advanced imaging helps clear up the picture.

Next Steps and Second Opinions

Following an ultrasound, it is recommended to opt for a dedicated pelvic MRI for a much sharper view of the uterine muscle wall to confirm whether a mass is truly benign.

Getting a second opinion from a specialist is a normal, proactive move. It is especially critical if:

  • A mass grows rapidly after menopause.
  • A patient develops new pelvic symptoms or bleeding years after your period has stopped.
  • The scans are flagged as atypical or difficult to read.

The good news is that uterine sarcomas are remarkably rare, making up just 2% to 5% of all uterine cancers. A patient needs to be cognizant by paying attention to changes in the body and asking questions about the scans.
