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.

What Are Some Other Indicators Of Dementia?

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.

Weight Loss Doesn’t Cause Dementia, Dementia Causes Weight Loss

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.

Former New York City Mayor Rudy Giuliani has been discharged from the ICU but will remain in the hospital for “some time” as he recovers from pneumonia, according to his spokesperson.

In a post on social media platform X, spokesperson Ted Goodman said Giuliani, 81, was hospitalized earlier this week in critical but stable condition.

Giuliani, who served as New York City's mayor from 1994 to 2001, was previously diagnosed with restrictive airway disease following the infamous 9/11 terrorist incident, where he “took down the mafia, saved New York City, and ran toward the towers on September 11th".

However, the incident left Giuliani with lasting health complications, Goodman said, adding that the former NYC Mayor "is recovering from pneumonia”.

“The virus quickly overwhelmed his body, requiring mechanical ventilation to maintain adequate oxygen and stabilize his condition,” Goodman said.

Calling him the "same fighter he's always been, and he's winning this fight,” Goodman said that the "mayor and his family appreciate the outpouring of love and prayers sent his way”.

Notably, Giuliani is a longtime ally of President Donald Trump. In 2025, Trump also announced awarding Giuliani with the Presidential Medal of Freedom, the country's highest civilian honor.

What Is Pneumonia?

Pneumonia is an inflammatory condition of the lung tissue, most often caused by infections. It can affect one or both lungs and can range from mild to life-threatening, especially in vulnerable populations like the elderly, young children, or those with underlying health conditions.

There are several types of pneumonia, classified based on their causes—bacterial, viral, and fungal—and each has distinct patterns of transmission and severity.

What Causes Pneumonia?

Pneumonia is not a single disease but a syndrome resulting from various infectious agents:

Bacterial Pneumonia: This is the most common type, often developing as a secondary infection after a cold or flu. Streptococcus pneumoniae is the most frequent culprit.

Viral Pneumonia: Caused by viruses like influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (COVID-19), this type often starts in the upper respiratory tract and spreads to the lungs.

Fungal Pneumonia: This type is less common and usually affects individuals with weakened immune systems. It's typically contracted through environmental exposure, such as to soil or bird droppings.

Early Warning Signs You Shouldn’t Ignore

Pneumonia can be insidious. It often begins with symptoms that mimic the flu: headache, fatigue, and fever. But as the infection progresses, signs become more serious:

• Persistent cough with green, yellow, or even bloody mucus
• Shortness of breath
• Chest pain, especially when breathing or coughing
• High fever, chills, and night sweats
• Confusion, especially in the elderly
• Nausea or loss of appetite

In a shocking case, a 68-year-old woman in the US who took antibiotics for inflammation developed an alarming skin reaction, leaving her skin black and blue.

The unusual case, reported in the New England Journal of Medicine (NEJM), noted that the woman developed dark patches on her skin very quickly, within two weeks of starting the drug — a course of minocycline, an oral antibiotic.

Two weeks before the onset of the skin changes, she had started taking 100 mg daily of oral minocycline to treat rosacea, which causes chronic inflammation and redness of the face.

Over the course of six weeks, dark patches appeared on the woman's arms and legs. It ranged from a bruise-like dark blue and purple to jet-black.

Her doctors also noticed blue-gray "hyperpigmentation" on the woman's forearms and shins, as well as on the sides of her tongue. The woman noted that the patches had first appeared on her legs before cropping up elsewhere.

Rosacea is a common skin condition that leads to the formation of small, red bumps and pus-filled pimples on the skin, and evidence suggests that antibiotics like minocycline can help eliminate those bumps.

Writing in the paper, Aarti Maharaj, from the University of Florida, shared that hyperpigmentation is a well-established side effect of minocycline, in which patches of skin become darker than the skin surrounding them.

While the condition typically develops after months of treatment, it may rarely occur with shorter courses, the expert said.

In this case, the woman was diagnosed with type II minocycline-induced hyperpigmentation, which is "defined by blue-gray discoloration of normal skin on the extensor surfaces of the arms and legs," according to Maharaj.

Doctors advised the patient to stop taking minocycline and to avoid sun exposure, as ultraviolet light is thought to worsen hyperpigmentation in these cases. Six months later, the hyperpigmentation in her limbs had "abated somewhat" but was still visible.

Minocycline And Hyperpigmentation

According to Mayo Clinic, minocycline belongs to the class of medicines known as tetracycline antibiotics. It works by killing bacteria or preventing their growth. However, this medicine will not work for colds, flu, or other virus infections.

It causes hyperpigmentation:

• Type I shows up as blue-black discoloration on scarred or inflamed skin on the face, rather than on healthy skin on the limbs.
• Type II leads to blue-gray discoloration of normal skin on the extensor surfaces of the arms and legs.
• Type III appears as muddy-brown pigmentation on sun-exposed areas of the body.

According to a frequently cited study, the side effect shows up in about 28 per cent of people in this population, although that research included only a small number of patients. The true incidence of the side effect is unclear, Live Science reported.

Once a person stops taking minocycline, the pigmentation can take months to years to dissipate, reports suggest. In type III cases, it sometimes never goes away.

Kidney disease is one of those conditions where myths quietly cause a lot of damage. Misinformation about symptoms, diet, medicines, and treatment can delay diagnosis, worsen kidney health, and prevent people from taking simple steps that could protect their kidneys early on.

Myth: Kidney disease is rare.

Fact: It’s actually quite common, but many people don’t even know they have it.

Myth: You’ll feel it if something is wrong.

Fact: Early chronic kidney disease (CKD) is usually silent, and symptoms often appear only after significant damage has already occurred.

Even something as simple as a slightly raised creatinine is often ignored.

Fact: Even mild elevations can signal a meaningful loss of kidney function.

Myth: Dialysis cures kidney disease.

Fact: Dialysis does not cure kidney disease. It only replaces some kidney functions to help keep the body in balance.

Myth: If dialysis is needed in Acute Kidney Injury (AKI), it means lifelong dialysis.

Fact: Dialysis in AKI may be temporary. In advanced CKD, however, it is often long-term or lifelong unless a kidney transplant is performed.

Diet myths don’t help either

Myth: More water is always better.

Fact: Hydration is important, but too much water isn’t helpful for everyone—especially in advanced CKD, where fluid intake may need to be restricted.

Myth: All kidney patients should eat the same diet.

Fact: Kidney diets are highly individualized. High-protein diets, often seen as healthy, can increase stress on damaged kidneys. Plant-based proteins can be a suitable alternative in many cases.

Myth: Herbal or indigenous remedies can cure or prevent kidney disease.

Fact: Many of these remedies are unregulated and may actually worsen kidney damage because of hidden toxins or heavy metals.

Myth: Painkillers are harmless.

Fact: Regular use of medicines like NSAIDs can quietly damage the kidneys over time.

At the end of the day, kidney disease isn’t just about treatment—it’s about awareness. Getting the facts right can make all the difference.
