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.

Five weeks after the launch of Novo Nordisk's weight loss pill, Wegovy, 38,220 US prescriptions have been reported by IQVIA for the same. The company shares too climbed up by 4% on Friday, and touched the levels last seen in October.
The oral version of the Wegovy pill became available to US patients earlier this month after the US Food and Drug Administration (FDA) approved it in December.
After injection by Novo Nordisk, of the same name, Wegovy, which has been on the market since 2021, its popularity grew so much that it was in short supply until February 2025. The pill version has now come out, which many experts believe will expand its accessibility. As the monthly supply of pill is expected to be cheaper than the monthly supply of the weight loss injection.
A study published in the New England Journal of Medicine show that a 25 milligram Wegovy pill led to 13.6% reduction in weight on average over 64 weeks. When compared to placebo, the result was only 2.2% of weight loss. Novo Nordisk says that those who stayed on the treatment and reduced their calorie intake, it would lead to a loss of 16.6% of their weight.
The first step lies in buying the correct and safe weight loss pill. Make sure the weight loss pills are clinically proven option for people to use to reduce their weight.
Take the pill with a glass of water. Make sure to always have the pill prescribed and follow the instructions that you GP has told. Store the pill in a cold place, however avoid freezing the medicine. Keep the medicine out of a child's reach. In some weight loss pills, if you miss your dosage, you can take it within 1 hour, however, clarify these doubts from your GP. A pill can usually be consumed within an hour of a fat-containing meal up to three times a day., however, the Wegovy pill must be taken on an empty stomach. Patients are advised not to eat, drink, or take other medicines for at least 30 minutes afterward. Thus, one must follow what is being prescribed for the best result, as the administering of the pill could vary based on the medication.
Most importantly, a healthy balanced diet, and a regular workout routine is also important will the person is on the pill.

Digestive problems such as nausea and vomiting remain the most common side effects of GLP-1 drugs. These issues were also reported in studies of the pill versions. Around 7 percent of participants taking the Wegovy pill stopped treatment because of side effects, compared with 6 percent in the placebo group. In orforglipron’s trial, up to 10 percent of patients discontinued treatment, compared with 3 percent on placebo.
One key difference lies in how the medications are used. The Wegovy pill must be taken on an empty stomach with a small amount of water. Patients are advised not to eat, drink, or take other medicines for at least 30 minutes afterward. Doctors say this requirement has limited the use of Rybelsus, the pill form of semaglutide approved for diabetes, compared with Ozempic.
Eli Lilly highlights that orforglipron was taken once daily in trials without restrictions on food or water, which may make it easier for patients to use consistently.

On February 13, Canadians across the country mark Wear Red Canada Day, a reminder that heart disease remains the leading cause of death for women. Yet despite the scale of the problem, many women still do not recognize their risk or their symptoms.
“We’re learning more and more each day about how heart disease uniquely affects women,” said nurse practitioner and researcher Rachel Ollivier in an interview with CTV News. She emphasized that awareness is still lagging, both among patients and within health-care systems.
According to the World Health Organization, cardiovascular disease accounts for roughly one in three deaths among women globally. In Canada, heart disease and stroke continue to be leading causes of death among women, and women are less likely than men to receive timely diagnosis or treatment.
Chest pain remains the most common heart attack symptom in both men and women. But Ollivier explained that women’s symptoms can often be subtler or feel different.
“For women, they often uniquely experience chest pain that seems like more of a discomfort or a tightness in the chest,” she said. Some women may feel pain in the left arm or jaw, unusual fatigue, nausea, vomiting, or discomfort between the shoulder blades.
Because these symptoms can be less specific, they are sometimes dismissed as stress, anxiety, indigestion, or exhaustion. Social factors also play a role. Women often juggle multiple responsibilities at home and work, and may delay seeking care. In some cases, their concerns may also be minimized within health-care settings.
Medical differences matter too. Women typically have smaller hearts and arteries, and plaque buildup behaves differently compared to men. Conditions such as spontaneous coronary artery dissection and microvascular dysfunction are seen more commonly in women, making diagnosis more complex.
Beyond symptoms, experts are urging greater recognition of the role hormones play in lifelong heart health.
“Endogenous estrogen is cardio protective,” Ollivier explained. As women enter the perimenopausal transition, estrogen levels fluctuate and gradually decline, and that protection is lost. This shift can lead to higher cholesterol levels and changes in fat distribution, increasing cardiovascular risk, particularly between the ages of 40 and 60.
Colleen Norris, a nursing professor at the University of Alberta and research lead of the CKHui LHHW Women’s Heart Health Research Collaborative who wrote on Yahoo Canada, believes the conversation needs to go even deeper.
She argues that ovaries have long been viewed only through the lens of reproduction. “The ovaries are not just reproductive organs. They are architects of women’s health across the lifespan,” she noted. Estrogen influences the heart and blood vessels, but also the brain, bones, kidneys, metabolism, and immune function.
Most women are never told that ovarian reserve and estrogen levels begin declining in their late 30s. By the time noticeable symptoms appear, biological changes may have already been underway for years.
Menopause itself is just one day, Norris explained. The larger reproductive transition surrounding it is what significantly increases vulnerability to chronic disease. Yet the health-care system often waits until disease develops before intervening.
Both experts stress that education is critical. Women with conditions such as polycystic ovary syndrome, pregnancy complications like preeclampsia or gestational diabetes, and those entering midlife should be particularly mindful of their cardiovascular risk.
Wear Red Canada Day is meant to spark awareness, but symbols alone are not enough. Experts are calling for better research funding focused on midlife women, improved medical education around ovarian aging, and more proactive screening during the reproductive transition.
Heart disease in women is not inevitable. But recognizing that symptoms can differ, and that hormonal shifts matter, could be lifesaving.

Seychelles Chikungunya Virus Outbreak: The United States warned travelers to be careful if they plan to visit the Seychelles islands anytime soon as it is currently undergoing a chikungunya outbreak. As per the Centers for Disease Control and Prevention (CDC), a 'Level 2' advisory for the island has been issued and travelers have been asked to 'practice enhanced precautions' if they do plan to visit.
Chikungunya is a mosquito-borne viral disease transmitted primarily by Aedes aegypti and Aedes albopictus, the same mosquitoes that spread dengue fever. Symptoms typically appear three to seven days after a bite and include sudden fever, severe joint pain, headache, nausea, fatigue, and rash in about half of cases.
However, there are certain unique symptoms of chikungunya. For instance, unlike a Dengue fever, chikungunya leaves lingering effects along with joint pain and fatigue that lasts up to weeks.
While common symptoms like high fever often >102 degree F is common there are other symptoms too, which includes:
Chikungunya symptoms usually occur with in 3 to 7 days after a bite. However, the symptoms could often last long. While fever could subside in a day or two, chronic symptoms especially like joint pain and muscle pain could last for months. Weakness too could persist.
A Level 2 travel advisory has been issued, which means the travelers are expected to practice enhanced precautions as compared to a Level 1 advisory that only asks travelers to practice usual precautions.
In more serious cases, Level 3 advisory is issued that asks travelers to reconsider non-essential travel, whereas a Level 4 advisory asks travelers to avoid all travel.
