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.

Endometriosis is a chronic disease affecting about 1 in 10 women worldwide. Diagnosis and treatment remain challenging, particularly for women with severe pain and other complications.
Now, US researchers have developed a targeted nanotherapy that showed promising results against endometriosis in early testing.
Scientists at Washington State University found that the treatment reduced endometriosis lesions, symptoms and pain sensitivity after a single dose in mice.
The findings were published in Advanced Healthcare Materials. Researchers hope to eventually test the treatment in humans.

The drug, niclosamide, was previously used to treat intestinal tapeworm infections in humans and is still used in animals.
Earlier research found that niclosamide could reduce endometriosis lesions and inflammation. However, it is not suitable for long-term use, limiting its potential as a treatment for a chronic condition.
To overcome this, researchers developed a nanotherapy that delivers niclosamide directly to cells associated with endometriosis.
“We found the disease-specific immune cell, and then we had a drug, but we couldn’t target the cell with the drug alone,” said Kanako Hayashi, professor at WSU’s School of Molecular Biosciences.
“So we used this nanocarrier that delivers the drug specifically to the disease site,” Hayashi said.
The team used a nanosized molecule called a dendrimer to bind with niclosamide and deliver it in a more soluble form.
In mice, a single injection reduced the size and number of lesions and lowered pain sensitivity.
“Although we still need to clear multiple phases, this study is telling us the efficacy is strong, and this nanocarrier is stable, so far, for two weeks—and we think we can go longer,” Hayashi said.
If the treatment remains stable for longer periods, researchers believe it could potentially be given less frequently. Hayashi said a monthly injection could be possible in the future, but this would depend on further testing.

Not yet. The treatment has only been tested in mice and must undergo further safety and efficacy testing before human trials.
Researchers also do not yet know whether it would ultimately be given as an injection or IV infusion.
Endometriosis affects an estimated 190 million women worldwide. It occurs when tissue similar to the lining of the uterus grows outside the uterus.
It can cause severe pelvic pain, painful periods, pain during sex and infertility. Symptoms are sometimes dismissed as a “bad period,” contributing to delays in diagnosis.
There is currently no cure, although treatments can help manage symptoms.
Treatment depends on symptoms, disease severity and fertility goals.
Hormonal medicines can help control pain and disease activity but may cause side effects and can affect fertility while being used.
Painkillers, including non-steroidal anti-inflammatory drugs, may help manage discomfort.
Laparoscopic surgery can remove lesions and endometriotic cysts and may help restore pelvic anatomy. It can also improve fertility in some women, although the disease can recur.
Lifestyle measures such as regular exercise, stress management and dietary changes may also support symptom management.

Lung development of the fetus depends on the physical and genetic health of the parents.
At birth, breathing begins with air from the environment, containing oxygen and other gases, and is influenced by known and unknown forces of nature. The air then passes through well-developed nostrils, which regulate the air temperature and prevent foreign bodies from entering the body and help protect against diseases.
Breath travels through the nasal passages, sinuses, pharynx (throat), larynx (voice box), trachea (breathing tubes), bronchi, small airways, air sacs, interstitial membrane, into thin-walled blood vessels that transport oxygen and collect gases and other substances to be expelled from the body.
The diaphragm, the muscle that separates the lungs from the abdomen, is the most powerful breathing apparatus.
The lungs in the early stages of life undergo dramatic changes from newborn→ infancy→ childhood→ puberty→ teenage→ adults→ middle age→ seniors. Factors influencing lung health risks keep changing with age, depending on genetics, environment & external factors.
The lungs and airways perform non-respiratory functions of protecting the body against harmful insults, both from within and external threats, and it also protects against insults received from other organs of the body. The lungs have a powerful defense mechanism protecting the body and also have hormonal, physical, and immunological defense mechanisms.
Alcohol awareness and the health risks associated with drinking, marking World No Alcohol Day. (Image Credits: iStock)
Every year on October 2, World No Alcohol Day urges people to pause and think about alcohol's place in everyday life. Here's where the day came from, and what current research actually shows about drinking.
It began in 2008, when India's then Union Health Minister, Dr. Anbumani Ramadoss, proposed a global alcohol-free day at the World Health Assembly in Geneva, according to National Day Calendar. The proposal drew support from 11 Southeast Asian countries.
The World Health Organization never formally adopted October 2 as an official global observance, according to a summary on Checkiday. There are, in fact, three dates tied to alcohol awareness worldwide: October 2 and October 3, observed by many groups as World Alcohol-Free Day or World Temperance Day, and November 15.
In India, October 2 is also a nationwide dry day, with no alcohol sales permitted, and is marked separately as National Anti-Drug Addiction Day.
The science has shifted since 2008. In January 2023, the World Health Organization stated plainly that no level of alcohol consumption is safe for health, publishing the position in The Lancet Public Health. The WHO said current evidence cannot identify any threshold below which alcohol's cancer-causing effects switch off.
Alcohol is classified as a Group 1 carcinogen, the same risk category as tobacco and asbestos, and is linked to at least seven types of cancer, including the most common cancers in men and women, bowel and breast cancer, according to the WHO.
Globally, alcohol was responsible for an estimated 741,300 new cancer cases and contributed to nearly 400,000 cancer deaths in a single year, as per Lancet-based estimates cited by the Union for International Cancer Control.
Previous research has showed some benefits of wine, but the majority scientific consensus now is that there is no safe levels of alcohol. The World Health Organization says health risks begin with the first drop of alcohol, meaning no level of consumption is completely safe or risk-free.
Cancer isn't the only risk. Alcohol use is tied to roughly 2.5 million deaths worldwide each year, including 320,000 among people aged 15 to 29, according to the WHO. Beyond individual health, alcohol-related harm also means more road accidents, violence, and strain on healthcare systems.
A May 2026 study linked alcohol to 62 disorders, ranging from heart and digestive diseases to mental and neurological conditions and cancers.
The study, published in the journal Addiction, showed that the fully alcohol-attributable conditions are mainly grouped under non-communicable diseases and injuries.
These include:
The data also included psychotic disorders, gastritis, ulcers, pancreatitis, fatty liver disease, pregnancy- and perinatal-related conditions such as fetal alcohol syndrome and fetal alcohol spectrum disorders, as well as external causes and injuries, including alcohol poisoning.
Excessive alcohol consumption is one of the leading preventable causes of illness and death in the US, according to the Centers for Disease Control and Prevention.
Research shows that alcohol accounts for approximately half of all liver-related deaths, while alcohol-associated cirrhosis has become the leading cause of liver transplants.
