Diabetes insipidus (DI) is a rare medical condition that disrupts the body's ability to regulate water, resulting in excessive thirst and an unusually high volume of urine. This condition affects the kidneys' ability to concentrate urine and causes individuals to produce between 3 and 20 quarts of dilute, colourless urine daily, compared to an average of 1 to 2 quarts. It is pertinent to note that DI is not related to diabetes mellitus, which disrupts the body's insulin production.
This condition results from damage to the hypothalamus or pituitary gland, which impairs the production or release of vasopressin, a hormone responsible for water retention. When vasopressin levels are inadequate, the kidneys fail to conserve water, leading to excessive urination. It can result from Brain injuries or surgeries, tumours, infections or inflammation and aneurysms.
Nephrogenic Diabetes Insipidus
This type occurs when the kidneys fail to respond to vasopressin, causing excessive fluid loss. Common triggers include chronic kidney disease, and electrolyte imbalances, such as high calcium or low potassium levels. Additionally, medications like lithium
and urinary tract blockages can also cause Nephrogenic DI.
A rare condition seen only during pregnancy, this occurs when the placenta produces an enzyme that breaks down vasopressin or increases prostaglandin levels, reducing kidney sensitivity to the hormone. Symptoms of this are usually mild and often resolve postpartum but can recur in future pregnancies.
In severe cases, dehydration may develop, manifesting as fatigue, dizziness, dry mouth, confusion, nausea, or fainting. Infants and children with DI may exhibit crankiness, poor feeding, slow growth, fever, or vomiting.
DI stems from issues with vasopressin production or response. Central DI arises from damage to brain structures, while nephrogenic DI relates to kidney dysfunction. Risk factors include:
- Genetic mutations affecting water regulation
- Certain medications like diuretics or lithium
- Metabolic disorders that alter calcium or potassium levels
- Brain injuries or surgeries
Diagnosis And Testing
Diagnosing DI involves a combination of medical history, physical exams, and specialized tests:
- Urinalysis: Evaluates urine concentration and glucose levels to distinguish DI from diabetes mellitus.
- Blood tests: Check electrolyte, glucose, and vasopressin levels.
- Water deprivation test: Measures changes in weight, blood sodium, and urine concentration during fluid restriction.
- MRI: Detects abnormalities in the hypothalamus or pituitary gland.
- Genetic screening: Identifies inherited risk factors.
Although DI is rare, affecting about 1 in 25,000 people, early diagnosis and targeted treatment can significantly improve quality of life. Researchers continue to explore its causes and treatments to better support those living with this challenging condition.

India’s cell and gene therapy ecosystem is beginning to attract a different kind of attention that is driven not just by healthcare demand, but by proprietary science and platform-led innovation.
For investors, however, the larger story may not be the funding round itself. It may be the problem the company is trying to solve.
CAR-T therapies have transformed outcomes for several difficult-to-treat blood cancers globally. But despite strong initial responses, relapse remains one of the field’s biggest limitations. One reason is antigen escape, which means cancer cells can change the markers that therapies use to identify them, making them harder to detect over time.
In an analysis of 4,129 CAR-T treated patients, relapse remained a substantial issue after single-target therapy, with 42.1% of relapses associated with loss of the CD19 target itself. The finding points to a larger issue: precision may not be enough if therapies lose visibility over time.
The response increasingly appears to be a move toward multi-target and more durable platforms. A bispecific CAR-T platform designed to recognize more than one tumor marker, to reduce relapse is crucial.
The science itself is becoming increasingly platform-oriented. Beyond broader targeting, recent work explored why immune cells themselves lose effectiveness over time and identified pathways associated with stronger persistence and memory. While still early, the broader implication is that future therapies may need to be designed not only to attack disease, but also to remain active longer.
For India, that creates a larger opportunity. Historically, advanced therapies such as CAR-T have remained expensive and heavily dependent on technologies developed elsewhere. The aim is to significantly reduce treatment costs while building indigenous capabilities across design and manufacturing.
The shift matters because biotech investing is increasingly moving beyond services and generics toward intellectual property and platform science. The transition from bedside observations to translational platforms may be where the next phase of healthcare innovation and investment gets built.

Colon cancer, medically known as colorectal cancer, was historically typical for people aged 50 or older. However, in recent years, the cancer that forms in the tissues of the large intestine has been increasing in prevalence in young adults. As many as one in five colorectal cancer patients today falls into this younger age group.
Now, a study published by the American Society of Clinical Oncology shows that marathons, which are one of the most celebrated physical activities, may be increasing the risk of the disease.
The team at Inova Schar Cancer Institute in Virginia, US, initiated the study after observing multiple “ultramarathoners” present to their cancer center with advanced colorectal cancer.
To probe the link, they recruited 100 runners to undergo colonoscopies — the gold standard for screening and preventing colorectal cancer. The team then looked at runners ages 35 to 50, who had either completed at least five marathons or two ultramarathons (any runs of 50 kilometers or more).
Presenting the findings at the 2025 American Society of Clinical Oncology (ASCO) annual meeting, Dr. Timothy Cannon, an oncologist at the Institute, stated that

Almost always, colon cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.
Moreover, the study found that the rate of advanced adenomas nearly tripled among the marathon runners, compared to the general population, at 4.5 -6 per cent.
In general, running and other forms of exercise are known to reduce the risk of developing colon and other cancers. At the same time, exercise-induced gastrointestinal injury is also believed to be associated with reduced blood flow to the intestines during long-distance running.
Notably, to date there is no evidence that definitively shows running causes polyps.
The new study presents a correlation — an increasing relationship between long-distance running and advanced adenomas. It does not prove that running directly causes the adenomas.

The new results suggest that “intensive long-distance running is a risk factor for advanced adenomas of the colon", said Dr. Timothy, in the paper. The team also called for "refining screening strategies" for marathon runners.
It is because runners put their bodies through a lot, which can raise the risk of chronic inflammation, enabling cancerous cells to grow.
Their high-caloric foods for immediate energy can slow down digestion and impact your overall colon health.
The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.
It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.
According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened, as the symptoms appear late, impacting treatment outcomes.
The common red flags for colorectal cancer include:

From being a macho dude, Bruce Willis’ personality has changed to becoming more ‘tender’ even as the 71-year-old action hero continues to battle dementia, according to his daughter Rumer.
“I’m so grateful I get to go see him,” Rumer, 37, said during a podcast interview. “Even though it’s different now, I’m so grateful.”
“There’s a sweetness. He’s always been this kind of macho dude, and there’s like a — fragile is not the right word, but — just a tenderness that maybe being Bruce Willis might not have allowed him in a certain way,” she added.
Bruce Willis is continuing into his third year living with the condition.
In March 2022, Bruce Willis, the media legend who dominated Hollywood in his prime, was diagnosed with dementia, and since then, his family has been sharing their struggle with his diagnosis and how slowly it has been taking a toll on his health.
The following year, his diagnosis was confirmed as frontotemporal dementia (FTD), which is a degenerative disease that slowly chips away at your motor skills, communication skills, etc. His wife, Emma Heming Willis, noted early signs were subtle changes in his speech, initially mistaken for a resurgence of his childhood stutter.
Rumer is the eldest daughter of Bruce and The Substance star Demi Moore, who were married from 1987 to 2000. The former couple also had Scout Willis, 34, and Tallulah, 32, together.
Although FTD is considered to be one of the rarest forms of dementia, Rumer said the disease is more “prevalent” than she realized.
“It’s wild to me. So many people come up to me now, and they say, ‘My uncle had FTD. My dad had this,” she said.

Earlier this year, in March, a hoax news of Bruce Willis’ death circulated. However, his representatives confirmed that the news is fabricated and that the actor is alive.
"He joins the long list of celebrities who have been victimized by this hoax. He's still alive and well. Stop believing what you see on the Internet," his official representative stated.
Frontotemporal dementia is a less prevalent type of dementia that mainly occurs in the frontal and temporal lobes of the brain. It tends to affect behavior, personality, language, and movement more than memory, particularly in its initial stages.
In contrast to Alzheimer's, which generally strikes older individuals, FTD can hit at an earlier age—sometimes as young as 40. The symptoms can range from changes in personality, emotional flatness, or the inability to show empathy to impulsiveness, so it is especially hard for spouses and children to cope.

The Mayo Clinic states that the symptoms of FTD vary depending on the most affected part of the brain. The progression is gradual but relentless.
