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.

Alcohol is often seen as harmful mainly for the liver or heart, but its impact goes much deeper—reaching down to our DNA. Even moderate drinking can silently cause changes at a cellular level, raising long-term health risks that may not be immediately visible. According to Dr. Amit Miglani, Director & HOD – Gastroenterology, Asian Hospital, the breakdown of alcohol in the body produces a toxic chemical called acetaldehyde, which can directly damage DNA inside our cells.
This damage disrupts the body’s natural repair mechanisms, allowing mutations to accumulate over time. Such mutations are linked to several cancers, including cancers of the mouth, throat, liver, breast, and colon. The insidious nature of this damage means that even when you feel healthy, harmful changes may be occurring beneath the surface.
DNA damage can be complex to understand, but its consequences are serious, explains Dr. Arun Kumar Giri, Director – Surgical Oncology, Aakash Healthcare. Normally, the body constantly repairs minor DNA errors. However, alcohol disrupts this repair process, leaving cells vulnerable to mutation and abnormal growth.
Dr. Giri adds that some people have genetic variations that make them break down alcohol more slowly. For these individuals, alcohol stays in the body longer, increasing the likelihood of DNA damage. Over years of repeated exposure, this can lead to uncontrolled cell growth and eventually cancer.
One of the most important points, Dr. Giri emphasizes, is that there is no entirely safe level of alcohol when it comes to DNA. The risk increases with both the frequency and quantity of drinking. Even occasional binge drinking can be harmful, meaning that how often you drink can be as important—or even more so—than how much you drink at one time.
This perspective shifts the discussion from asking “How much alcohol is too much?” to “How often am I exposing my cells to alcohol-induced damage?” Protecting DNA health requires regular monitoring and mindful drinking habits, even for those who feel healthy today.
Alcohol-induced DNA damage is not just a short-term concern. Over time, the accumulation of mutations can significantly increase cancer risk and other serious diseases. Regular health check-ups, a balanced lifestyle, and moderation, or complete avoidance of alcohol are crucial steps for safeguarding your genetic health and overall well-being.
Dr. Amit Miglani highlights that “It’s not just about the organs you can feel being affected today; it’s about protecting your long-term health, especially your DNA, for the future.”
Dr. Arun Kumar Giri advises, “Understanding the cellular impact of alcohol helps people make informed choices about their drinking habits. Even small changes can significantly reduce the risk of long-term damage.”

New research suggests that menopause may be linked to a loss of grey matter in the brain, which could help explain why women face a higher risk of dementia compared to men. Scientists from the University of Cambridge analysed data from 124,780 women to explore how menopause affects the brain and whether hormone replacement therapy (HRT) might help protect against cognitive decline.
The researchers found that menopause was associated with reduced levels of grey matter, an essential part of the brain involved in thinking, memory, emotional processing and movement. The findings also noted that this stage of life is often accompanied by anxiety, depression and sleep problems. Previous research has already shown that menopause can affect cognitive abilities such as attention, language, learning and memory.
Published in the journal Psychological Medicine, the research divided participants into three groups: women who had not yet reached menopause, post-menopausal women who had never used HRT, and post-menopausal women who were taking HRT. Participants answered questions about sleep patterns, anxiety and depression, and some completed cognitive tests measuring memory and reaction time.
Around 11,000 women also underwent magnetic resonance imaging (MRI) scans, allowing scientists to closely examine brain structure. On average, menopause began at age 49 among the participants, and women who started HRT typically began treatment at around the same age.
The findings showed that post-menopausal women were more likely to struggle with insomnia, get less sleep overall and feel more fatigued. Interestingly, women using HRT reported the highest levels of tiredness across all three groups, even though they slept for a similar amount of time as those not taking HRT.
All post-menopausal women, regardless of whether they were using hormone therapy, reported greater fatigue compared to women who had not yet experienced menopause. Researchers also observed that this stage of life had an impact on cognitive function.
Dr Katharina Zuhlsdorff, from the psychology department at the University of Cambridge, explained: “As we age, our reaction times naturally slow down. This happens to both women and men and is part of normal ageing. You might still reach the right answer to a quiz question, but younger people tend to respond faster. Our findings suggest menopause speeds up this slowing process, while HRT seems to slow it down slightly.”
The study identified significant reductions in grey matter volume among post-menopausal women. These changes were seen in the hippocampus, which plays a key role in learning and memory, the entorhinal cortex, which supports memory formation and spatial awareness, and the anterior cingulate cortex, which helps regulate attention and emotions.
Professor Barbara Sahakian, the senior author of the study from the department of psychiatry, said: “The brain areas where we observed these changes are the same regions commonly affected by Alzheimer’s disease. Menopause may make women more vulnerable later in life. While it does not explain everything, it could help clarify why dementia affects nearly twice as many women as men.”
Michelle Dyson, chief executive of the Alzheimer’s Society, noted that women account for roughly two-thirds of people living with Alzheimer’s disease in the UK. “Although we do not yet fully understand why women are more affected than men, hormones are thought to play a role,” she said.
“This large-scale study strengthens evidence that menopause has an impact on the brain, including physical changes such as reduced brain volume. However, without long-term follow-up to see whether participants later develop dementia, we cannot be certain that these menopause-related brain changes directly increase dementia risk.
“There are steps people can take today to lower their dementia risk, including regular exercise, avoiding smoking and cutting back on alcohol. Anyone concerned about themselves or a loved one can use the Alzheimer’s Society dementia symptoms checklist as a starting point before speaking to a GP.”
The research also found that women taking HRT were more likely to report mental health challenges. However, the analysis suggested these women already had poorer psychological wellbeing before starting hormone treatment.
Dr Christelle Langley, from the psychiatry department, said: “Menopause is something most women will experience, and it can be a major life change whether or not HRT is used. During this time, healthy habits such as staying active, exercising regularly and eating a balanced diet become especially important to help reduce some of its effects.”
Dr Louise Newson, a GP and women’s hormone specialist, added: “Many women notice changes in memory and concentration around menopause. This study suggests these symptoms may have a biological explanation rather than being brushed off as stress or ageing, highlighting menopause as a key window for protecting brain health and providing personalised care.”

More than 10 million adults, young people, and children in the UK are currently living with arthritis, according to a 2025 report by Arthritis UK. The NHS states that osteoarthritis is the most common form of the condition nationwide.
As per Cleveland Clinic, osteoarthritis develops gradually as joints become stiff and painful due to wear and tear. Symptoms can vary depending on the joint affected and the extent of damage, but pain, swelling, and reduced movement are common. While medication is often prescribed to manage symptoms, the NHS cautions that some commonly used treatments can carry health risks if taken long-term or without proper guidance.
One of the most frequently used pain relief options is non-steroidal anti-inflammatory drugs, commonly known as NSAIDs.
NSAIDs, or non-steroidal anti-inflammatory drugs, are commonly prescribed by GPs to help relieve pain, swelling, and inflammation. They are available in several forms, including tablets, capsules, suppositories, creams, gels, and injections. Some NSAIDs can be purchased over the counter, while stronger versions require a prescription.
These medicines are often relied upon for day-to-day pain relief by people with osteoarthritis, particularly during flare-ups.
The NHS advises that NSAIDs may not be suitable for everyone. Extra caution is recommended for people with asthma, a history of stomach ulcers, angina, or those who have previously experienced a heart attack or stroke. The NHS also advises that individuals taking low-dose aspirin should always consult their GP before using NSAIDs.
Long-term or incorrect use can increase the risk of stomach bleeding, cardiovascular problems, and kidney issues, making it important to review pain management plans regularly.
Consultant Rheumatologist Dr Rod Hughes explains that natural compounds are increasingly being explored as supportive options for joint health.
“Natural compounds derived from plants have long been used in both traditional and modern medicine to support joint health. One such compound is GOPO, which is derived from rose hips (Rosa canina). Research indicates that GOPO can help relieve joint pain due to its anti-inflammatory properties,” he says.
“Rather than simply masking symptoms, GOPO works by helping to regulate the body’s inflammatory response, which is a key driver of joint stiffness, swelling, and discomfort. It offers a promising alternative to traditional painkillers, with fewer risks of side effects, making it a more sustainable option for managing joint discomfort.”
According to Dr Hughes, lifestyle measures form the foundation of osteoarthritis management.
“Lifestyle choices play a central role in relieving osteoarthritis pain and helping people stay active,” he explains. “Research shows that regular, gentle exercise supported by physiotherapy, such as walking, swimming, and yoga, can be highly effective.”
“These activities help keep joints mobile and strengthen the muscles and ligaments that support them, which reduces stiffness and eases pressure on painful joints. It is also important to balance activity with rest to avoid flare-ups caused by overuse.”
Weight management is another key factor in controlling osteoarthritis symptoms. “Maintaining a healthy body weight is especially important,” says Dr Hughes. “Extra weight places additional load on joints, particularly the knees and hips, which can worsen pain and accelerate joint damage. Even modest weight loss has been shown to significantly reduce pain and improve mobility.”
Interestingly, diet can also play a role in managing inflammation linked to osteoarthritis. “Eating plenty of fresh fruit and vegetables, whole grains, nuts, and seeds, along with at least two portions of oily fish each week, provides antioxidants and omega-3 fatty acids that help reduce inflammation and protect against cell damage,” Dr Hughes explains.
“In my practice, I often recommend combining these dietary changes with natural supplements such as turmeric or GOPO to provide additional support for joint health.”
For patients hoping to reduce their dependence on NSAIDs, Dr Hughes stresses the importance of medical supervision.
“Any reduction in NSAIDs should be done gradually and under the guidance of a healthcare professional. This helps ensure pain remains well controlled while avoiding sudden flare-ups or withdrawal issues,” he says.
“By combining regular movement, physiotherapy, supportive nutrition, and appropriate natural supplements, many patients can take a more balanced approach to managing chronic joint pain. Over time, these strategies may allow people to rely less on medication while maintaining a good quality of life.”
