A new report published in The Lancet Diabetes & Endocrinology challenges the conventional definition of obesity, and urges a shift from the reliance on Body Mass Index (BMI) to a more nuanced approach. This is supported by over 50 global medical experts. The report also recommends splitting the term "obesity" into two categories: "Clinical obesity" and "Pre-clinical obesity". This aims to improve diagnosis and treatment for over a billion people worldwide living with obesity.

Clinically Obese

This applies to individuals whose obesity has progressed to a disease state, manifesting in organ damage, heart disease, type 2 diabetes, or other health complications. These individuals could also experience symptoms like breathlessness, joint pain, or impaired daily functioning. Treatment also involves medical interventions, including weight-loss medications or surgery.

Pre-Clinic Obese

Whereas the term "pre-clinic obese" refers to those who are overweight but not yet exhibiting health issues. While they may be at risk of developing obesity-related conditions, their organ function and overall health remain intact. What they need is preventive care, which includes dietary guidance, counselling, and regular monitoring to avoid and reduce future health risks.

What does the study say?

The study, led by Professor Francesco Rubino from King's College London emphasizes that obesity is not one-size-fits-all condition. This means it should rather be treated as a spectrum as some individuals maintain normal organ function despite being classified as obese. There are others who may face severe health complications too. However, the current method of calculating obesity based on BMI often leads to misdiagnosis or inadequate care.

The report also states that BMI, while is useful for analyzing population trends, is a flawed unit of measuring individual health. Therefore, there is a need to redefine obesity, and healthcare professionals can provide more precise care by distinguishing those who need immediate medical intervention and those who require preventive strategies.

Limitations of BMI, Why It Falls Short?

BMI is used to classify individuals as underweight, healthy weight, overweight, or obese based on their height and weight. It is calculated by dividing weight in kilograms by health in meters squared. However, there are reasons while it falls short.

•Muscle vs Fat: Athletes or muscular individuals often have high BMIs despite the low body fat

•Fat Distribution: BMI does not measure fat around the waist or organs, which could be more dangerous to one's health.

•Individual Health Variation: It also overlooks the specific health conditions such as heart diseases or diabetes, or any other, while evaluating a person's category in terms of weight.

Scope Of Study

By redefining obesity, the study could transform the approach to diagnosis and treatment. It can focus on individual health risks rather than BMI alone. Healthcare providers can also offer tailored care. This also will ensure hat weight-loss medications like Wegovy or Mounjaro are prescribed only to those who genuinely require it.

As per Professor Louise Baur from the University of Sydney, a Children's obesity expert said that this redefinition allows both adults and children to receive more appropriate care while reducing over-diagnosis and unnecessary treatments.

PMOS is often discussed mainly in connection with periods, hormonal changes and pregnancy. However, women’s health is much broader than fertility. Changes linked to hormonal health can also influence weight, energy levels, skin, hair, metabolism and emotional well-being.

This is why women should not focus only on whether their periods are regular or whether they are planning a pregnancy. Looking at overall health can help identify concerns early and support better long-term well-being.

PMOS can affect more than periods

Changes in the menstrual cycle may be one of the first signs that something needs attention, but they are not the only concern. Women may also notice changes in weight, acne, hair growth or hair thinning, tiredness and mood.

Persistent or unusual changes should not be ignored, even if a woman is not planning to have children. Speaking to a healthcare professional can help identify the possible cause and decide whether further evaluation is needed.

Think beyond fertility

Fertility is an important part of women’s health, but it should not be the only focus. Women should also pay attention to their overall metabolic health, including blood pressure, blood sugar, cholesterol and weight when appropriate.

A balanced diet, regular physical activity, adequate sleep and maintaining a healthy weight can support better health. Medical care should also take into account age, lifestyle, family history and existing health conditions.

Mental health matters too

Hormonal and reproductive health concerns can affect emotional well-being. Worries about periods, weight, appearance or future fertility may contribute to stress, anxiety or low mood. Women should feel comfortable discussing these concerns with their doctor. Mental health is an important part of overall health and should be addressed along with physical symptoms.

How can women take better care of their health?

Women can start by tracking changes in their menstrual cycle and paying attention to other symptoms. Regular physical activity, nutritious food, adequate sleep and stress management can support overall well-being.

Those planning pregnancy should discuss their plans with a doctor in advance. However, even women who are not planning pregnancy should continue regular health monitoring.

Tips for long-term health

• Keep track of menstrual changes and other symptoms.

• Maintain a balanced and nutritious diet.

• Stay physically active.

• Prioritise good sleep and stress management.

• Monitor blood pressure, blood sugar and cholesterol when advised.

• Do not ignore persistent hormonal or menstrual changes.

• Discuss fertility plans early with a healthcare professional.

• Pay attention to mental and emotional health.

PMOS should not be viewed only through the lens of periods or pregnancy. Women’s health also includes metabolic, hormonal, physical and emotional well-being. By looking beyond fertility, monitoring health regularly and making healthy lifestyle choices, women can take better care of themselves at every stage of life.

When people think of Alzheimer's specifically, memory loss is usually the first thing that comes to mind — forgetting recent conversations, repeating questions, struggling to recall familiar names. But Alzheimer's rarely announces itself through memory alone. It can also show up in how a person communicates, makes decisions, behaves, and manages the everyday tasks that once came naturally. People often mistake dementia and Alzheimer's for the same thing; however, dementia is not a single disease but a broad term for a decline in memory, thinking, and reasoning severe enough to interfere with daily life. Alzheimer's disease is the most common cause of dementia, accounting for a majority of cases.

Signs Families Often Misread

These early changes are easy to misattribute. A person who withdraws from social life may seem to be "losing interest." Someone who grows irritable may be written off as difficult or set in their ways. A family member who lets bills slide may appear distracted rather than unwell. Only when such shifts persist and clearly depart from a person's usual character do they warrant closer attention.

Communication And Language

Difficulty finding a familiar word now and then is normal. But losing the thread of a conversation, or struggling to express thoughts that once came easily, is different — and when this worsens over time, it's often family and friends who notice first.

Judgement And Everyday Decision-Making

Independence can erode quietly. Someone who has handled the household finances for decades may start making uncharacteristic decisions or find bills confusing. Following a familiar recipe, managing medication schedules, or planning a routine outing may become surprisingly hard. Family members frequently pick up on these lapses in judgement before they notice any memory trouble at all.

Behaviour And Personality

A once-sociable person may pull back from hobbies and company. Others may become anxious, suspicious, or emotionally distant in ways that feel out of character. These shifts can be hard for loved ones to make sense of — especially when they seem intentional — but they often reflect real changes in how the brain is processing and responding to the world, not a change in who someone chooses to be.

Daily Functioning

There's a meaningful difference between misplacing your keys occasionally and repeatedly leaving objects in strange places with no memory of how they got there. Likewise, forgetting one appointment is ordinary; missing commitments again and again despite reminders is not. Trouble navigating familiar streets, preparing a simple meal, or keeping up with personal care can point to a broader change in cognitive function.

Not A Diagnosis In Itself

None of these changes automatically means Alzheimer's. Many have other causes — some of them treatable — which is exactly why a medical assessment matters: it helps identify what's actually going on and whether further evaluation is needed.

What helps: Patterns, Not Incidents

For families, tracking patterns is far more useful than reacting to isolated moments. When did the changes start? How often do they happen? Are they starting to affect independence? This kind of observation gives doctors much more to work with than a single anecdote.

How families respond matters too. Correcting or criticising someone for changes they can't control tends to breed frustration on both sides. A patient, supportive approach protects their dignity while making it easier to get them the care they need.

Alzheimer's, in short, is not only a disease of memory. Its earliest clues can surface in conversation, judgement, behaviour, or the small routines of daily life. Recognising these signs isn't about assuming the worst — it's about noticing when something is genuinely different, and knowing when that difference is worth a doctor's opinion.

By Dr. Tanushree Chawla, Neurologist, PB Health

For decades, childhood vaccination was one of the clearest public health success stories in Europe. But a new study published in The Lancet Regional Health—Europe, suggests that progress has started to slip, and in some countries, it has slipped quite noticeably.

The research led by a team from the Università Cattolica del Sacro Cuore in Rome looked at vaccination coverage across seven different vaccines in European Union countries, tracking data all the way from 1980 to 2024. What it found was not a sudden collapse, but something arguably more concerning: a slow, steady stall that has crept in over the last few years without much attention.

Which Childhood Vaccine Rates Dropped?

According to the research, recent declines were most widespread for vaccines against

• Hemophilus influenzae type b
• polio,
• hepatitis B
• diphtheria-tetanus-pertussis.

Where the Decline Is Happening

Since 2019, sixteen countries have seen vaccination rates drop for four or more of the vaccines studied. Bulgaria, Cyprus, Ireland, the Netherlands, Romania, and Sweden stood out in particular, with all seven vaccines showing a downward trend in recent years.

The pattern wasn't uniform everywhere, though. Germany and Spain saw declines in five of the seven vaccines, while France and Italy told a more mixed story, with four vaccines improving even as three others slipped.

At the higher end, Luxembourg and Portugal managed to maintain at least 95 percent coverage across all seven vaccines, a benchmark most countries are still trying to reach. Romania, on the other hand, fell below 80 percent, making it the lowest performer in the study.

Why This Is Happening Now

According to the researchers, the timing of this decline is not a coincidence. Most of it began somewhere between 2019 and 2022, a period that overlaps almost exactly with the Covid-19 pandemic and its aftermath. Routine vaccination services were widely disrupted during that time, and the study suggests that many countries simply haven't fully recovered since.

There's also a broader factor at play: vaccine hesitancy, which researchers describe as a growing contributor to the decline, separate from any pandemic-related disruption. In other words, this isn't only about missed appointments during lockdowns. It also reflects a shift in how some parents and communities are approaching vaccination altogether.

What This Means Going Forward

Vaccination remains one of the most effective tools available for preventing serious childhood diseases, and researchers are clear about what's at stake if this trend continues. A sustained drop in coverage doesn't just affect individual children; it also weakens herd immunity, making entire communities more vulnerable to diseases that had largely been kept under control for years.

The study was direct about what needs to happen next, stating that international, national, and community-level action will be necessary to reverse these trends. Without it, the progress that took decades to build could continue to erode, quietly, one missed vaccination at a time.
