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.

Types Of Diabetes Insipidus

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.

Gestational Diabetes Insipidus

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.

Symptoms And Warning Signs

• Severe thirst, often leading to the consumption of over a gallon of water daily
• Frequent urination (polyuria), sometimes exceeding 20 quarts per day
• Nighttime urination and bed-wetting
• Weakness, muscle pain, and preference for cold drinks

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.

Causes And Risk Factors

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.

Climate change is an environmental issue, but its effects are reaching the eye clinic. Hotter summers, intense ultraviolet radiation, polluted air, shifting pollen seasons and extreme rainfall can affect the eyes.

Because the eye’s surface is exposed to the environment, changes in temperature, humidity and air quality may produce symptoms. Five risks deserve attention in India.

Heat and Dry-Eye Disease

Extreme heat, dry winds and prolonged air-conditioning can accelerate evaporation of the tear film that protects the eye. Dehydration may compound the problem. Burning, grittiness, redness, watering and blurred vision are common warning signs.

Outdoor workers, drivers, older adults and contact-lens users may be especially vulnerable. Hydration, protective glasses and preservative-free lubricating drops recommended by an ophthalmologist can help.

Cumulative Ultraviolet Damage

Sunlight can affect more than the skin. Acute, intense ultraviolet exposure may injure the corneal surface and cause photokeratitis, producing pain, watering, light sensitivity and blurred vision. Exposure over years is associated with pterygium a fleshy growth on the eye and certain forms of cataract.

Choose sunglasses labelled UV400 or offering 99–100 per cent UVA and UVB protection. Dark lenses without verified UV protection are not adequate. A broad-brimmed hat provides protection.

Air Pollution and Ocular-Surface Inflammation

Particulate matter, vehicle emissions, smoke, ozone and construction dust come into direct contact with the tear film. They may destabilise it and trigger inflammation, worsening dry eye, redness and allergic conjunctivitis. On days with poor air quality, limit avoidable outdoor exposure, use wraparound glasses and avoid rubbing the eyes.

Artificial tears may wash irritants from the surface, but persistent symptoms require examination rather than repeated use of over-the-counter “whitening” drops.

Longer Allergy Seasons

Changing temperatures, rainfall patterns and plant cycles can alter the amount and timing of airborne pollen. Combined with dust and pollution, this may result in more frequent or prolonged allergic-eye symptoms. Intense itching, watering and swollen eyelids are typical.

Cold compresses can provide relief, but rubbing may damage the ocular surface and, in susceptible people, contribute to corneal problems. Anti-allergy drops should be selected with medical guidance. Steroid eye drops must never be self-prescribed because misuse can raise eye pressure, promote infection and damage vision.

Eye Infections After Extreme Rainfall and Flooding

Heavy rain, waterlogging and disrupted sanitation increase exposure to contaminated water and surfaces. Crowding during outbreaks may also facilitate the spread of infectious conjunctivitis through hands, towels, cosmetics and shared personal items.

Do not splash floodwater or questionable tap water into the eyes, and never rinse contact lenses with water. Pain, marked light sensitivity, reduced vision, corneal whiteness or symptoms in a contact-lens wearer require urgent assessment.

Climate-related eye problems are not confined to one season. Prevention begins with UV protection, clean hands, hydration, sensible exposure reduction and timely eye examinations. Sudden loss of vision, severe pain, flashes, new floaters or an eye injury should always be treated as an emergency.

More women in the US and UK are seeking testosterone to manage menopause symptoms, with some turning to online pharmacies without a prescription, according to media reports.

There are no US Food and Drug Administration (FDA)-approved testosterone products specifically indicated for women. Australia has approved a low-dose testosterone product for postmenopausal women, while the UK and New Zealand permit some female-dosed formulations, although availability varies.

What’s Happening In The US?

Reuters reported that off-label testosterone use is rising in the US, mainly to treat persistently low sexual desire associated with menopause. Some clinicians are also prescribing testosterone for symptoms such as fatigue and loss of muscle strength, despite a lack of medical guidance supporting these uses.

Prescriptions for low sexual desire reportedly rose 146% between January 2023 and July 2026. However, many pharmacies and health insurers continue to deny these prescriptions.

Why Are UK Women Turning To Testosterone?

The BBC reported that some women in Wales are posing as men to buy testosterone from online pharmacies because of difficulties accessing NHS prescriptions.

There has also been a “very sharp increase” in testosterone referrals to the NHS for postmenopausal women.

Menopause specialist Dr Michelle Olver said she had seen women with testosterone levels up to 12 times the safe level after buying the hormone online, putting them at risk of permanent side effects.

Although testosterone is often called a male hormone, women also produce it, primarily through the ovaries and adrenal glands. Levels generally decline with age.

Some women are prescribed testosterone for distressing loss of sexual desire. Others are seeking it for fatigue, impaired thinking, low mood and loss of muscle strength.

The FDA is set to hold a public workshop on September 17 to examine testosterone use in menopausal women. The agency says off-label use is growing, while questions remain about its effects on sexual function, mood, cognition, muscle and bone health, as well as long-term cardiovascular and breast cancer safety.

What Does The Evidence Say?

Menopause does not automatically mean a woman has a “testosterone deficiency.”

Notably, there is no established testosterone level below which an otherwise healthy woman is diagnosed as testosterone deficient. A blood test alone also cannot determine whether low testosterone is responsible for symptoms such as fatigue, low mood or loss of sexual desire.

However, the Menopause Society and other medical organizations support testosterone use in menopausal women with hypoactive sexual desire disorder.

“We do not have any evidence in women that it will improve muscle mass or bone density or mood or well-being or really any other metric,” said Dr Stephanie Faubion, director of Mayo Clinic's Center for Women's Health and medical director of The Menopause Society.

“What testosterone is being touted for in the lay public and on social media is not really what we have data for,” she said.

Are There Any Side Effects?

According to Cleveland Clinic, testosterone treatment generally isn’t recommended for women with cardiovascular disease, liver disease or hormone-sensitive cancers such as breast or uterine cancer.

Excess testosterone can cause acne, increased facial or body hair and scalp hair loss. Higher doses may also lead to voice deepening and clitoral enlargement, some of which can be irreversible.

Testosterone should therefore not be used in higher doses as a way to boost energy, muscle strength or libido.

You've probably seen gallon jugs with stuff like "BORG o'clock somewhere" scrawled on them in Sharpies, often showing up at parties. Well, there's actual research on them now, and it's not great.

The study by Rutgers University, published in the Journal of Studies on Alcohol and Drugs, surveyed over 100 college students about their BORG habits. The study finds significant health risks.

What Is BORG?

BORG stands for "Blackout Rage Gallon," and it's basically a personal-sized jug loaded with liquor, water, and whatever flavoring you're into. It started gaining traction around 2020 and hasn't slowed down since the hashtag #borg has racked up millions in views on TikTok alone.

Here's the number that stands out, though. A full BORG can pack up to a fifth of liquor. That's about 17 standard drinks. In one jug. And it is meant for one person.

The study pointed out that drinking games have always been part of college culture. But BORG drinks might be worse than most, mainly because of how they're made. Mixing hard liquor with sweet flavors can make people drink more without realizing how much alcohol they're actually consuming, and the fact that people often share sips of each other's jugs only adds to the risk.

"Excessive drinking in young adults has been fueled by drinking games for many decades. But the mixing of hard liquor and additive flavorings in BORGs may be particularly harmful given the sweetness of the beverage and the lure of sharing one's BORG and tasting others' concoctions," said lead researcher Andrea King, a professor of psychiatry and behavioral neuroscience at the University of Chicago, US.

When Can BORG Drinks Go Wrong?

The actual numbers from the study are rough. Almost a third of students said they'd blacked out from a BORG at some point, not just "drunk," actually blacked out, meaning their brain stopped saving memories from that stretch of time.

Nearly 20 percent of students said they threw up, and nearly 6 in 10 admitted to saying or doing something embarrassing. And this is just the students who actually admitted to having done this. The actual count could be much higher. Some cases were serious enough to end in injuries or trips to the emergency room.

According to the World Health Organization, there is no safe level or risk-free amount of alcohol consumption that does not affect health.

BORGs: The ‘Safe Drinking’ Myth

What's even more interesting, however, is how this trend began in the first place. BORGs were initially promoted on social media as the more responsible choice when it came to drinking. The idea was for everyone to bring their own jug instead of sharing cups, so as to avoid the spread of germs during the pandemic.

Some recipes online even threw in electrolytes or caffeine, supposedly to dodge hangovers or keep people from getting too drunk. Students still shared their BORGs constantly, and the added ingredients did nothing to stop the harmful effects of drinking so much alcohol at once.

Even knowing all this, however, a lot of students said they're not planning to stop. That's part of why this study seems to emphasize the fact that awareness matters so much, both for students and for their parents.

As King put it, "There are choice points along the way, ranging from whether to attend a BORG event, and if one does attend, whether to bring a BORG beverage and how much (if any) alcohol to put in the beverage. It doesn't have to be all-or-none, as being aware and mindful to minimize risks can be key."
