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.

A 31-year-old Brazilian beauty queen, Maiara Cristina de Lima Fiel, has reportedly died after suffering a sudden heart attack.
de Lima Fiel, a young mother, was due to compete in a beauty pageant next week. She reportedly had no major health issues. Paramedics spent more than an hour trying to save her life but she tragically did not recover, The Daily Mail reported.
Her untimely death has sparked grief and shock among her community and followers, and has also reignited concerns over unexpected cardiac events in seemingly healthy individuals.
de Lima Fiel was crowned Miss Londrina last year in a prestigious regional beauty pageant and also came runner-up in the 2025/26 edition of Miss Sarandi, The Daily Mail reported.
"She was such a committed, dedicated young woman," the report quoted Vitor Tavares, organizer of the contest Maiara, as saying. She was due to compete on April 29.
"I had the pleasure of meeting her in person at the end of last year when she confirmed her participation as Miss Londrina. From that moment, it was clear how seriously she took this dream," he added.
While detailed medical circumstances have not been publicly disclosed, such sudden cardiac events in young adults are often linked to underlying, sometimes undiagnosed, heart conditions or acute cardiovascular episodes.

Acute coronary syndromes, or heart attacks, are on the rise among young adults.
While there are some genetic predispositions for premature heart attacks, the majority of the risk is attributed to the increased incidence of conventional risk factors in young people, such as

Doctors are now seeing them in people as young as their late 30s and early 40s, especially those with high-stress jobs.
“They mistake early signs for lifestyle issues: acidity after a heavy dinner, shoulder pain from sitting at a laptop, or tiredness from long hours," Pankaj Vinod Jariwala, Interventional Cardiologist at Yashoda Hospitals, told HealthandMe.
Dr Krunal Tamakuwala, cardiologist at KD Hospital, Ahmedabad, pointed out that the real danger is not that these heart attacks are completely "symptomless," but that their symptoms are so common that they are easily ignored.
By the time a person finally sees a doctor, their heart may already be seriously damaged.
“Sometimes, it arrives silently, hidden behind complaints we consider minor. That is why doctors urge patients not to ignore symptoms that linger or feel unusual, even if they seem harmless at first,” Dr Tamakuwala told HealthandMe.

Body odour is natural, but sometimes it may signify a health issue. When body odour is persistent, unusual, and/or changes suddenly, it could indicate a possible health problem. Sweat itself is odourless, but when it interacts with bacteria on the skin, it creates the odour that we associate with body odour. Some of the factors that may alter the way the body smells are medications, hormones, and lifestyle choices. Dr Pooja Kanumuru, a dermatologist at Apollo Clinic, Indiranagar, addressed this for Health and Me.
There are medical conditions that can cause body odour to be unusual or excessive: bromhidrosis; bacterial and/or fungal skin infections; and systemic diseases such as diabetes, liver disease, and kidney disease. For example, a diabetic with poor management may have a fruity-smelling body odour, whereas an infected person may have a foul body odour due to bacterial activity.
Body odour becomes an issue when there is no improvement despite proper hygiene. If body odour is associated with other symptoms such as fatigue, unexplained weight loss, fever, and/or abnormal skin changes, these should be addressed to determine the cause and seek appropriate assistance. Medically associated body odour does not decrease with normal methods such as bathing and/or the use of deodorants but tends to persist.
Body odour can also be affected by the following:
Hormonal and metabolic changes during certain periods of life (for example, puberty, menstruation, pregnancy, and menopause) can change the amount of sweat produced, which can also alter the intensity of its smell.
Thyroid disorders, especially hyperthyroidism, can sometimes result in increased sweating.
Rare metabolic disorders, such as trimethylaminuria, can result in a strong, fishy-smelling body odour due to the inability to break down certain substances in the body.
It is interesting how certain unusual odours can offer important clinical insights. For example, if a person has a fruity odour, this could indicate difficulties with diabetes control. A fishy smell could be a sign of a metabolic disorder, while an ammonia-like smell may indicate problems with kidney function. Meanwhile, musty or foul odours may suggest an infection or liver dysfunction. While these odours cannot be used as stand-alone diagnoses, they can help guide further medical evaluation.
Diet and lifestyle choices significantly affect body odour. For example, foods such as garlic, onions, spicy foods, red meat, and alcohol can exacerbate body odour, while poor hydration, high stress levels, smoking, and obesity can worsen it further. Additionally, wearing very tight or non-breathable clothing may cause perspiration and bacteria to become trapped, thereby worsening body odour.
Keeping your body clean, applying the right type of antiperspirant, wearing breathable materials, and maintaining a healthy diet can all help in managing body odour. However, if body odour persists or worsens, you should consult a doctor. A prompt medical assessment can identify the cause and allow your physician to discuss possible treatments, including topical medications and procedures that reduce excessive sweating.

The human skin is the body's largest organ, a dynamic barrier spanning roughly 1.7 square meters in the average adult. It blocks pathogens, regulates temperature, and signals systemic distress.
What compromises this barrier most reliably are decisions made in the course of an ordinary day; how a body is cleaned, what materials rest against it for hours, and whether moisture is managed or ignored
Most skin infections, rashes, and fungal conditions during primary care can be prevented. They develop when the skin is exposed to moisture, friction, or microbes for extended periods, which weakens its natural protective barrier. Once this barrier is compromised, bacteria, fungi, and irritants can take hold. Seeing it this way makes hygiene a matter of health, not just routine care.
Many skin conditions linked to hygiene arise from a combination of factors, including excess moisture, repeated friction, and unchecked microbial growth.
Moisture, whether it is from sweat, urinary leakage, or inadequate drying after bathing, softens the stratum corneum, the protective outermost layer.
Softened skin abrades under friction far more readily than dry skin. In zones like the groin, underarm, and the skin folds of infants, this combination creates ideal conditions for intertrigo, candidal infections, and bacterial folliculitis.
Infants represent the most vulnerable case study. Diaper dermatitis, affecting a significant proportion of children at some point in infancy, develops when occlusive material holds urine and stool in prolonged skin contact.
The enzymatic activity of fecal matter sharply raises skin surface pH, stripping the acid mantle and triggering an inflammatory response. Consistent nappy changes, appropriate absorbent capacity, and barrier creams together are solutions to this cycle. When any one element is compromised, either frequency of change or material quality, dermatitis rates climb demonstrably.
For adolescent and adult women, an equivalent vulnerability exists during menstruation. Extended contact with saturated absorbent materials elevates local moisture and pH, producing an environment conducive to bacterial vaginosis and vulvar dermatitis. Clinical guidance consistently recommends regular pad or tampon changes irrespective of flow volume, the interval matters as much as saturation levels.
As per the systematic review by Bowen et al. (2015) in PLOS ONE, over 162 million children in low- and low-middle-income countries are affected by impetigo at any given time, with most cases occurring in tropical, resource-limited regions. These figures underline how everyday hygiene practices influence skin health and help prevent infections from spreading.
Urinary tract infections in women and girls are closely linked to perineal hygiene. The urethra’s proximity to the rectum makes it easy for faecal bacteria, particularly Escherichia coli, to spread if cleaning is inadequate. Changing underwear regularly, wiping front to back, and using breathable fabrics can help reduce this risk.
Fungal infections require particular attention in warm, humid climates, where heat and moisture create ideal conditions for dermatophytes to thrive and persist. As per Gupta, Chaudhry, and Elewski (2003) in Dermatologic Clinics, tinea corporis, tinea cruris, and other superficial dermatophytoses show increased prevalence in developing and tropical countries due to elevated temperatures and sustained humidity, which create an environment conducive to fungal proliferation.
India's combination of heat, humidity, and fabric choices creates a near-constant conducive environment for dermatophyte infections like tinea cruris (groin ringworm). These infections respond well to antifungal treatment but return when underlying hygiene practices are not followed appropriately. Dry skin after bathing, moisture-wicking undergarments, and clean, well-ventilated footwear are among the most evidence-backed preventive measures available.
Hence for females, during periods, it's important to have a sanitary napkin or period panty which has rash free and leakage prevention capabilities.
Hygiene practices for adults, including the use of well-fitted absorbent products, have consequences that extend beyond comfort. Improper or prolonged use of adult diapers can create conditions for recurrent urinary tract infections (UTIs).
Hygiene-related infections place a heavy burden on public health. In India, poor menstrual hygiene is linked to school absenteeism, reproductive tract infections, and delays in seeking care because of stigma. Outcomes are shaped by access to products, awareness, and their quality.
Clinical recommendations are only actionable where products and information reach people reliably. In rural and peri-urban India, access to affordable, functional hygiene products such as absorbent sanitary pads, quick dry & reliable baby / adult diapers, and effective skin-cleansing agents remains uneven. Affordability and quality often sit at opposite ends of the market.
When hygiene products fail in absorbency, breathability, or durability, the burden falls on the user's skin and health. A diaper that leaks prematurely does not reduce dermatitis risk; a sanitary pad which leaks fails mid-cycle, does not support menstrual hygiene management. Product performance, therefore, is inseparable from health outcomes.
The evidence base for hygiene as preventive medicine is extensive and long-established. The gap that persists is between knowledge and consistent practice, sustained by habit formation, reliable access to appropriate products, and normalisation of conversations around intimate health.
Maintaining daily hygiene by using the right products and following regular routines decreases the risk of infections, protects the skin, and promotes overall long-term health.
