Weight loss is usually considered a good thing, unexpected and extreme weight loss can be a sign of something in your body going very wrong. There could be some underlying issues that are causing your body to pull weight and nutrition from your muscles and body fat to keep you going. As you grow old, your limbs grow weaker, and same for your muscles, so you do lose some weight as you age, but losing a lot of it too quickly could be a sign of something much worse, Dementia. A recent study published in JAMA Network Open 2025 Cardiometabolic Trajectories Preceding Dementia in Community-Dwelling Older Individuals, has identified potential early indicators of dementia, including significant weight loss and specific digestive changes, appearing years before noticeable cognitive decline.
The study showed that people who later got dementia had their Body Mass Index, or BMI, go down faster than those who stayed healthy. BMI is a way to see if someone's weight is healthy for their height. This drop in BMI started happening many years before they were told they had dementia, sometimes as early as 11 years ago. Also, these people often started with a lower BMI to begin with. So, even though everyone's weight might change a little as they get older, the people who developed dementia had a much bigger and faster weight loss.
Along with their BMI, the size of their waist also changed. People who ended up with dementia had smaller waist sizes, and this difference was noticeable about 10 years before they were diagnosed. This means that their bodies were changing in ways that showed up long before they or their doctors noticed any problems. So, not only was there weight loss, but also a loss of abdominal fat. This measurement is important because fat around the waist can be related to other health issues.
The study also found changes in their blood. Specifically, the "good" cholesterol, called HDL, went up in people who developed dementia. This increase happened about five years before they were diagnosed. It's tricky because HDL is usually seen as a good thing for your heart. But in this case, it seems like it might be a sign of changes happening in the brain. Scientists are still trying to understand why this happens.
When we see that people with dementia lose weight, it's easy to think that the weight loss is what caused dementia. But experts think it's the other way around. They call this "reverse causation." This means that the brain changes that cause dementia also cause people to lose weight. The brain changes can affect things like appetite, how the body uses food, and how people go about their daily lives. For example, people might forget to eat, have trouble making meals, or move around less.
While the study revealed a lot about different indicators of dementia and bodily changes, there are many limitations to the study. Everyone loses some weight as they get older. So, it's hard to know when weight loss is just a normal part of aging and when it's a sign of dementia. The study found that people with dementia lost weight faster, but it's still tricky to tell the difference in everyday life. Doctors need to look at other things, like memory tests, to figure out if someone's weight loss is a cause for concern.
If someone is losing weight without trying, and they're also having problems with their memory or thinking, it's important to talk to a doctor. It's not just about the weight loss; it's about the whole picture.

Many men believe that as long as they feel healthy, active, and free from major illness, their fertility remains intact. While men do not have a sudden fertility cut-off like women, age still plays an important role when it comes to male fertility. Currently, a large number of men wish to start families later in life, often thinking their good health guarantees easy conception and fatherhood. They often neglect the age factor, even though it is linked to hormonal imbalance, stress, and genetic issues. A large number of men are unaware of their fertility health and continue to suffer. However, even in the absence of visible health problems, older men may face unexpected fertility challenges. Dr Madhukar J Shinde, Fertility Specialist at Nova IVF Fertility, PCMC, Pune, answered this for Health and Me.

Decline in sperm quality: Various studies have confirmed that as men age, sperm count, movement, and shape can slowly decline. Even if the numbers appear normal, DNA damage in sperm increases with age, which can reduce the chances of successful fertilisation.
Men must stay in touch with a fertility consultant who can design an appropriate treatment plan. The expert will evaluate them thoroughly and suggest lifestyle modifications such as a well-balanced diet, exercise, stress management through meditation, and medication for conditions such as diabetes, hypertension, and cholesterol. Awareness helps men take informed steps towards parenthood, even later in life. Certain pre-medications, including antioxidants advised by a fertility consultant, may significantly help in reducing DNA fragmentation, which contributes to poor sperm function. Therefore, men should prioritise their reproductive health, stay informed, and not suffer in silence.

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.
Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.
A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.
Baduanjin is a slow, structured movement, focused on deep breathing and meditation.
Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.
In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.
"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.
Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.
It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.
Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.
They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.
Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced
Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.
"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost
approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.
"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

Back pain is a common problem seen among middle-aged men and women, especially those sitting for prolonged hours. The pain experienced is mainly due to poor posture, lack of physical activity, obesity, and stress.
However, for some, the pain occurs in the mid-back, indicating a far more serious problem. While it may appear like chronic back pain, it may actually signal the risk of spinal tuberculosis, which can creep in silently, according to doctors.
If left untreated, the dangerous infectious disease can lead to paralysis and spinal deformity.
“If your back pain persists for months, it is localized, or if it worsens with cough/breathing, don’t ignore it; seek expert evaluation,” said Dr. Sudhir Kumar, a neurologist from Apollo Hospitals Hyderabad, in a post on social media platform X.
Dr. Kumar also shared the case of a 55-year-old man suffering from back pain for four months.
The man’s blood tests, nerve conduction studies, and MRI (neck and lower back) appeared normal. Yet his pain did not go away. He found no relief with painkillers, muscle relaxants, and rest.
Notably, his pain increased while coughing and taking deep breaths.
“That is not a random symptom. Pain that increases with coughing is suggestive of spinal nerve root irritation or compression. This immediately shifts thinking from “muscle pain” to spine pathology,” said Dr. Kumar. The expert advised an MRI of the dorsal (thoracic) spine, which suggested spinal TB.
The “MRI dorsal spine showed involvement of D8–D9 vertebrae, disc edema and paravertebral collection. These findings were suggestive of Spinal Tuberculosis,” said the neurologist, popularly known as the Hyderabad doctor.
Unlike lung TB, where prolonged fever or coughs are a key risk factor, Dr. Kumar just had persistent back pain and no fever, weight loss, or any such “typical TB symptoms”.
“This is why Spinal Tuberculosis is dangerous. It can be silent and slow, and the diagnosis can be easily missed, until it causes paralysis and spinal deformity,” Dr. Kumar said.
Tuberculosis of the spine is also known as Pott’s disease, and is named after Sir Percival Pott, who described it in 1779.
Also called tuberculous spondylitis, it is a severe form of skeletal tuberculosis where the Mycobacterium tuberculosis bacteria infect the vertebrae — typically spreading from the lungs to the spine via the blood.
Unlike routine back pain, pain due to spinal TB is persistent, progressive, and does not respond to usual rest or medication.
Early identification is crucial to prevent complications such as spinal deformity or neurological damage, Dr. Manisha Mendiratta, Director & Head – Pulmonology, at Sarvodaya Hospital, Faridabad, told HealthandMe.
The common symptoms to watch out for include:
Early evaluation is key. If symptoms persist, a detailed clinical assessment should be done. Doctors may recommend:
Dr. Mendiratta urged the need for ensuring early diagnosis and complete treatment of any TB infection. Further, maintaining good immunity through balanced nutrition and rest, as well as avoiding ignoring persistent or unusual back pain, is crucial to preventing spinal TB.
The doctor also stressed the need for regular follow-ups in people with a history of TB exposure, and to never stop TB treatment midway.
