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.

People living with obesity and diabetes often feel healthy in their day-to-day life, but some of the most dangerous changes may be happening silently inside their bodies.

The liver is one of the first organs to be affected. In many cases, fat slowly accumulates in the liver without causing any pain, discomfort, or obvious symptoms. This is why fatty liver disease is often called a “silent condition.” By the time it is detected, it may already have progressed to an irreversible stage.

Excess body fat, particularly around the abdomen, disrupts how the body processes sugar and fats, placing continuous stress on the liver. Because of this silent progression, experts now strongly recommend that people living with obesity and type 2 diabetes should proactively check their liver health, even when they feel completely well.

Obesity is closely linked with liver damage through a series of metabolic changes that develop over time. When the body becomes resistant to insulin, fat begins to accumulate in liver cells, triggering inflammation and gradual injury.

If this continues unchecked, the condition can progress from simple fat accumulation to more serious stages, including metabolic dysfunction-associated steatohepatitis (MASH), where inflammation and liver cell damage become more significant.

Over time, this may lead to fibrosis (scarring of the liver), and in advanced cases, cirrhosis, which can severely affect liver function. Further, patients with fatty liver may directly present with liver cancer, which can occur in up to 20% of patients.

How Common Is Fatty Liver In People With Diabetes And Obesity?

In India, the burden of metabolic dysfunction-associated steatotic liver disease (MASLD) or fatty liver is rising and is now recognised as a common metabolic condition. Studies from the Indian subcontinent estimate that 1 in 3 people may have MASLD. Fatty liver is particularly common among individuals with metabolic risk factors.

It is seen in nearly 40–80% of people with type 2 diabetes and 30–90% of those with obesity, often without clear symptoms.iv Hospital-based trends also suggest increasing detection in younger age groups, reflecting changes in diet, reduced physical activity, and more sedentary lifestyles.

What Liver Checks And Preventive Measures Should You Follow?

Preventive measures to be followed:

• If you live with excess weight/obesity and type 2 diabetes or PCOS (polycystic ovarian syndrome) or dyslipidemia, seek early consultation with a physician or hepatologist.

• Your doctor may request routine metabolic screening:

• Regular liver function tests as part of annual health check-ups

• Ultrasound screening for individuals with obesity or diabetes

• Monitoring blood sugar, cholesterol, and triglyceride levels

• Liver scarring scan (annually for patients with diabetes/obesity)

• Avoiding long-term neglect of “mild” or borderline test results

With rising obesity rates in India, early liver screening should become a routine part of preventive healthcare. Even modest weight reduction, improved diet quality, and regular exercise (approximately 150 minutes per week of moderate-intensity exercise (example: brisk walking, gardening, swimming, cycling) or 75 minutes of vigorous exercise (example: weight training) can significantly reduce liver fat and inflammation within 3-6 months.

However, once the disease progresses to MASH or fibrosis, reversal becomes more difficult and may require long-term medical management. Early-stage fatty liver disease is reversible in many cases. In fact, medications can even reverse liver fibrosis (early scarring), but in only 25% of patients. Simple homemade food is sufficient to prevent these lifestyle diseases, and there is no need for “fancy online diets or supplements”.

Our forefathers lived longer by consuming homemade food and water without any supplements. Newly approved therapies such as semaglutide (GLP1 analogues) have been shown to resolve steatohepatitis and reduce liver fibrosis. These liver benefits do not appear to be explained solely by weight loss, suggesting a broader potential impact on liver health.

The absence of symptoms does not mean the absence of risk. Taking care of the liver early is not just about preventing disease; it is about protecting long-term health, energy, and quality of life.

There is a conversation that comes up in almost every consultation, and it is rarely the one the patient came prepared for. After graft numbers, hairline design, cost and downtime have been discussed, the question of smoking and drinking inevitably follows — and the answer is usually a shrug: occasionally, socially, nothing serious.

Yet of all the variable that determines what a patient sees in the mirror eighteen months later, these two are among the very few fully within their control, and among the most underestimated.

What Smoking and Alcohol Do to the Scalp

The hair follicle is one of the most metabolically demanding structures in the body, dividing faster than almost any other cell population and depending entirely on a dense network of microscopic vessels feeding its base. Nicotine constricts those vessels; over years, repeated narrowing combined with low-grade inflammation contributes to perifollicular fibrosis — scarring that gradually chokes the follicle.

Alcohol takes a different route, depleting the zinc, iron, folate, B12 and protein hair is built from, while fragmenting sleep and raising cortisol — both of which push follicles prematurely into their resting phase. For a transplant candidate, this matters twice over: it reflects donor-area quality, and it signals the kind of healing environment the grafts are about to enter.

Why the First Week After Surgery Is So Critical

For the first few days after surgery, a transplanted follicle is essentially cut off from its blood supply, surviving on nutrients diffusing in from surrounding tissue.

New capillaries begin connecting around day four or five, with full revascularisation taking seven to ten days — the most vulnerable window in the graft's life. Smoking attacks it from two directions: nicotine causes sustained vasoconstriction after every cigarette, while carbon monoxide binds haemoglobin more readily than oxygen, so the reduced blood reaching the scalp also carries less oxygen.

The result is rarely dramatic — just poorer graft survival, patchier density, and a final outcome thinner than the graft count promised. Patients often read this as bad luck; it usually isn't. Notably, this applies equally to vaping, hookah and smokeless tobacco like gutkha or khaini — the delivery method changes, but the nicotine doesn't.

Alcohol's More Immediate Risk

Alcohol's damage is more mechanical. It causes vasodilation and impairs clotting, meaning patients who've been drinking beforehand bleed more during surgery — which makes graft placement less precise and can dislodge grafts already sited.

Afterward, the same vasodilation worsens normal post-op swelling, its diuretic effect fights the hydration healing tissue needs, and its immune-suppressing effect arrives just as the scalp carries thousands of small open wounds. There's a medication risk too: alcohol combined with post-op antibiotics, anti-inflammatories or steroids raises the chance of gastric irritation or a genuinely unpleasant systemic reaction.

Recommended Windows

For smoking: stop at least two weeks before surgery (four is better), and stay off it for two weeks to a month afterwards — the long lead-in accounts for how slowly small-vessel and immune function normalise, and the long tail covers graft revascularisation.

For alcohol: stop five to seven days before, and avoid it for ten to fourteen days after, or as long as medication continues, since its effects reverse faster. One caveat worth repeating: patients often say they've "stopped" when they've merely cut back. A single cigarette produces measurable scalp vasoconstriction — in this window, occasional isn't the same as fine.

The Myth That Lifestyle Stops Mattering

A costly misconception is that once surgery is done, lifestyle no longer matters. It's a half-truth: transplanted follicles, taken from the DHT-resistant back and sides of the scalp, are permanent and won't miniaturise. But a transplant only redistributes existing hair — every native follicle remains susceptible to ongoing loss.

If that native hair keeps thinning, overall density falls even though every graft survives, and patients often mistake this for transplant failure. In reality, the surroundings have receded, accelerated by smoking, poor sleep, chronic stress and poor nutrition. Surgery buys a foundation; lifestyle determines how long the picture around it holds.

Practical Guidance

Honesty at consultation matters — knowing a patient smokes heavily changes the surgical plan toward more conservative density and staging, which protects the result. The pre- and post-op window should be treated as non-negotiable, even if permanent quitting feels distant; a defined four-week commitment is far more achievable than an open-ended one.

Switching to vaping or nicotine gum isn't automatically safe — it removes carbon monoxide and tar, but nicotine, the actual vasoconstrictor, remains, so replacement therapy should be discussed with the surgeon. Fundamentals also help: adequate protein, iron and vitamin D, seven to eight hours of sleep, hydration, and gentle movement once cleared.

Turning Surgery into Leverage

Finally, surgery itself can be motivating. Patients who've just invested significant money and recovery time in their appearance are often more driven to quit than at any other point in

It is difficult to determine emotions because of the neurological differences, the surrounding in childhood, the psychological ways of survival, and absence of emotional training.

Alexithymia or "emotional blindness" is the neuropsychological trait associated with severe problems with identification, recognition, and description of the person's emotions. Alexithymia is not a psychiatric disease but a personality trait.

It is characterized by the inability to identify and distinguish emotions and body sensations, difficulty of finding the words to express feelings, inability to understand facial expression and body language of another person and emotional detachment during stressful situations.

It is diagnosed in people with autism spectrum disorder, depressive disorder, generalized anxiety disorder and after traumatic brain injuries. It can be inherited or acquired as a result of childhood trauma, abuse or neurological damage.

The Brain Science Behind Alexithymia

The cause of alexithymia is the brain wiring and neurological differences. Therefore, there is impaired interception, which is the inability of the brain to recognize its own physical sensations. Also, an unusual structure of the brain regions like amygdala and insula, that regulate emotions, makes difficult to decode emotional signals.

Early childhood environment and emotional competence must be developed in childhood, because, without that, there can be emotional neglect and emotional vocabulary deficiency. Due to the inability to interpret emotional data, the person misses the compass that directs decisions and self-calming. This leads to emotional outburst, panic, hyperarousal, social and psychological consequences.

How Alexithymia Differs From Emotional Numbness

Emotional numbness is the transient psychological state caused by acute trauma, deep grief or burnout.

The lack of emotional intelligence is the lack of social and emotional competence, when the person feels his emotions correctly, but he cannot control temper, lacks empathy, makes inappropriate social decisions or do not know what kind of effect his behaviour causes on the room.

But alexithymia is different since it is long-term personality trait and the person is unaware of the particular emotion.

In terms of neurodevelopment, the insular cortex and the anterior cingulate cortex (ACC) are the structural core of the brain's salience network. They work as a translator, transforming chaotic physical sensations into recognizable emotional experience.

Although there isn't any cure for alexithymia, one can improve his emotional awareness through certain measures. Interoceptive training where individuals are taught how to associate physical body sensations (such as tightness in the chest) with particular emotions (such as stress).

The use of emotion wheel or list of emotional words to bridge the link between vague physical sensation and precise description. Mindfulness, which involves observing oneself without judgment or without trying to suppress those internal feelings right away. And it is always good to seek professional help from a psychologist or a counselor.
