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.

Nearly one in seven couples struggles with infertility, meaning they haven’t been able to conceive despite having regular, unprotected sex for a year or more. In roughly half of these couples, male infertility is at least partially responsible. Causes can range from low sperm production and abnormal sperm function to blockages that prevent sperm delivery.
Illnesses, injuries, chronic conditions, lifestyle factors, and other influences may contribute. Not being able to conceive can be stressful and emotionally challenging, but a variety of treatments exist for male infertility. But are there natural ways to improve male fertility? We spoke with Dr. Ruchi Jain, Fertility Specialist at Nova IVF Fertility, Kolkata, to get her insights.
Male infertility refers to a man’s inability to cause pregnancy in a fertile female partner, often due to problems with sperm production, function, or delivery. After a year of trying (or six months if the woman is over 35) without success, doctors usually examine both partners. About 50% of infertility cases involve male factors, with the most common issues being low sperm count (oligospermia), poor motility, abnormal morphology, or the complete absence of sperm in the ejaculate (azoospermia), Dr Jain explained. Some causes are temporary, some treatable, and some may be permanent.
Many men experience noticeable improvement by focusing on lifestyle changes and addressing reversible medical conditions. Research shows that a nutritious diet (like a Mediterranean-style or “prudent” diet), regular moderate exercise, quitting smoking, reducing alcohol, losing excess weight, and avoiding heat or tight underwear can improve sperm quality.
Dr. Jain noted, “These adjustments don’t guarantee conception, but they often enhance sperm count, motility, and DNA quality enough to support natural conception or assisted reproductive techniques.”
Certain medical conditions that cause infertility can often be reversed. For example, varicoceles, which are enlarged veins in the scrotum—are a common cause; repairing a significant varicocele frequently improves semen parameters and can lead to pregnancy.
Hormonal issues, such as low testosterone or pituitary disorders, may also be treated with medication. Dr. Jain said, “Temporary causes like infections, medications, or recent fevers can lower sperm counts, which often normalize within a few months once the underlying issue is resolved. Professional guidelines highlight that many male-factor infertility cases can respond well to medical or surgical treatment.”
Dr Jain told us that some conditions are extremely difficult or impossible to “cure.” Genetic disorders (like Klinefelter syndrome), congenital absence of the vas deferens, severe testicular failure, or damage from chemotherapy or radiation usually prevent normal sperm production.
In these cases, treatment focuses on alternatives: retrieving sperm directly from the testicles, using IVF with ICSI (intracytoplasmic sperm injection), donor sperm, or adoption. Recent studies show that sperm retrieval after certain procedures can improve success rates, but outcomes depend heavily on the underlying condition of the testicles.
Interest in antioxidants (vitamins C and E, zinc, L-carnitine), herbal remedies (maca, ginseng), and bioactive compounds (resveratrol, curcumin) is rising. Some research reports modest improvements in sperm quality, while other studies show mixed or minimal effects.
However, experts caution that supplements aren’t a miracle solution, quality varies, and evidence remains limited. Always consult a specialist before trying supplements, as some may interact with medications or cause harm at high doses.
Even with personal lifestyle changes, environmental factors play a major role. Global air pollution, pesticides, plastics, and other endocrine-disrupting chemicals are linked to long-term declines in sperm counts. While an individual cannot control these entirely, reducing exposure (avoiding unnecessary plastics, limiting contact with heat or chemicals, choosing organic or well-washed produce) and advocating for public health measures are practical steps. Recent global reviews have highlighted these environmental threats to male fertility.
Male infertility is not always permanent. Many causes, such as obstructions, varicoceles, hormonal imbalances, or infections—can be treated or reversed. Lifestyle changes and certain medical or surgical interventions can improve outcomes for many men.
Conversely, genetic factors, severe testicular damage, and gonadotoxic injuries are usually irreversible, requiring assisted reproductive techniques or other family-building options. A structured diagnostic assessment and an individualized treatment plan—including genetic counseling when needed are essential.

What happens when antibiotics stop working? We are so used to consuming antibiotics for everything that slowly our bodies are rejecting this. The sole reason is that bacteria have become smart. And experts believe that if this continues, it could slip the world back into an era where even a minor infection would be dangerous.
Antibiotics are used to treat almost all infections. However, with the sudden outbreaks, the misuse and overuse of it is slowly leading to antibiotic resistance or antimicrobial resistance (AMR). As per the World Health Organization (WHO), AMR occurs when bacteria, viruses, fungi, and parasites no longer respond to antimicrobial medicines.
As experts warn, infections we currently consider minor could soon turn life-threatening. A routine urine infection, a scraped knee, or a mild chest infection, problems that usually resolve within days, may refuse to heal in the future. Bacteria evolve rapidly, and when exposed to unnecessary or incomplete antibiotic courses, they adapt and learn to survive. That’s when even our strongest medicines begin to fail.
Antibiotics do far more than treat common illnesses; they quietly support some of the most advanced medical procedures.
“Joint replacements, heart surgeries, organ transplants all rely on antibiotics to prevent dangerous infections. Chemotherapy patients, whose immunity is low, survive because antibiotics protect them from everyday microbes. Remove this safety net, and suddenly these sophisticated treatments become far riskier, even impossible,” explained Dr. Sunil Havannavar Senior Consultant - Internal Medicine, Manipal Hospital Sarjapur to IndiaTV.
Antibiotic resistance doesn’t arrive with a bang. It builds slowly, every time antibiotics are misused—taken for viral infections, stopped halfway through, used without prescription, or demanded unnecessarily for fevers. Each misuse gives bacteria an opportunity to evolve. Doctors are already seeing cases where high-power, last-resort antibiotics are needed for infections that should have been easily treatable.
In fact, a new global study in The Lancet’s eClinicalMedicine has drawn serious concern about the sharp rise of antimicrobial resistance (AMR) in India, placing the country at the centre of what many specialists now consider a fast-moving superbug crisis. The research, titled Preprocedural screening for multidrug-resistant organisms in endoscopic retrograde cholangiopancreatography: an international, multicentre, cross-sectional observational study, shows that Indian patients had the highest worldwide rates of multidrug-resistant organisms (MDROs) among those undergoing a common endoscopic procedure.
A superbug is a strain of bacteria that no longer responds to one or more groups of antibiotics that previously worked well. This can happen through enzyme production such as carbapenemases, changes in drug targets, increased pumping out of drugs or shifts in the cell wall that block antibiotics from entering, as per National Institute of Health. When bacteria gain resistance to several antibiotic classes, the list of possible treatments becomes very small. Such resistance makes infections tougher to manage because routine medicines no longer work, leading to more severe illness.
The situation is serious, but not irreversible. We can slow the rise of resistance if everyone plays their part.

Magnesium and melatonin are both popular supplements, especially among people looking to get more shuteye, but can combining them improve your sleep? Some research indicates that taking magnesium and melatonin together could improve sleep quality, though stronger, larger studies are needed to confirm the effect.
Studies on using magnesium and melatonin together are limited, but some evidence suggests it could benefit sleep in certain individuals.

As per Health, one study focusing on women with polycystic ovary syndrome found that taking both magnesium and melatonin improved sleep quality. Another study reported that people with sleep difficulties who used a combined magnesium-melatonin supplement for four weeks noticed modest improvements in how well they slept.
The exact reason why the two work together is not completely understood, but magnesium and melatonin may influence each other in a way that supports sleep.
“Magnesium does have an effect on melatonin levels,” said Marie van der Merwe, PhD, coordinator of the applied physiology and nutrition doctoral program at the University of Memphis, speaking to Health. “The amount of magnesium you have can influence how well your body produces melatonin.”
You don’t necessarily need to take the two supplements at the same time to benefit, van der Merwe noted. It’s fine to take magnesium in the morning and melatonin before bed.
The takeaway: There could be a link between magnesium and better sleep, but more research is needed to be sure.
Magnesium is a vital mineral that supports nerve and muscle function, regulates blood pressure and blood sugar, and contributes to the formation of bone, protein, and DNA. As per Mayo Clinic, it is also commonly taken to help with sleep, but it is not without risks.
Some studies suggest magnesium may help sleep by:
Improving sleep quality: Ensuring adequate magnesium through diet or supplements may help people with deficiencies sleep better and ease anxiety.
Reducing muscle tension: Magnesium can help relax muscles and relieve tension, which can make it easier to fall asleep.
Research on magnesium for sleep is limited. Supplements aren’t regulated by the FDA for safety or effectiveness and carry potential risks:
Delayed effect: It may take several weeks before magnesium supplements noticeably improve sleep.5
Side effects: High doses can cause diarrhea, nausea, and stomach cramps.7
Drug interactions: Magnesium can interfere with some medications, reducing their effect or increasing side effects. Talk to a doctor before starting any new supplement.7
Melatonin is a well-known sleep aid, though it’s actually a hormone your body naturally produces to regulate sleep-wake cycles.⁸ “Melatonin is in charge of running the [internal] clock, and it really is important for regulating your circadian rhythms,” van der Merwe said.
Works quickly when needed: Unlike magnesium, melatonin can act soon after taking it, making it useful for occasional sleepless nights.
May help you fall asleep faster: Studies show that a 2-milligram dose of melatonin helped some people fall asleep about nine minutes sooner than placebo.
Supports sleep timing: Melatonin can help shift workers, travelers with jet lag, or those with irregular sleep schedules align their sleep patterns.
Melatonin can help with some sleep difficulties but won’t fix all sleep disorders, van der Merwe said. Like magnesium, melatonin isn’t FDA-regulated:
Long-term effects unclear: There’s limited data on the safety of long-term melatonin use.
Medication interactions: Melatonin may interact with antibiotics, antidepressants, and birth control.
Caution for certain groups: It’s generally not recommended for children or people with dementia, and should be used carefully by those with seizures or on blood thinners.
It’s wise to speak with a healthcare professional before starting any new supplements, alone or in combination.
Van der Merwe emphasized that sleep problems can stem from issues that supplements alone won’t fix. Conditions like cardiovascular disease, type 2 diabetes, and depression can affect sleep.
If you want to try one or both supplements, a doctor can help determine the best timing for magnesium, melatonin, or a combined product.
“Melatonin [should] increase at night,” van der Merwe explained, so it is crucial to take it at the right time. Taking it in the morning can disrupt your internal clock.
Even though sleep-support supplements like magnesium and melatonin have grown in popularity, it’s important to consult a professional to see if they will help in your situation.
