We all must have come across the phase: this is why women live longer than men. These are all over the social media, where men are performing more often than not, some experiments, without gears, just for fun, "in the name of science". The caption reads: this is why women live longer. However, is there really a science to it, other than the fact that women choose to do things more safely?

In the United States, women have a life expectancy of about 80, whereas men have 75. Women outlive men and this holds true regardless of the country women live, the money they make, and other factors. In fact, it is true for most other mammals too.

Dr Dena Dubal, a professor of neurology at the University of California, San Francisco told the New York Times, "It is a very robust phenomenon all over the world, totally conserved in sickness, during famines, during epidemics, even during the times of starvation."

But what are the reasons? These reasons are often more complicated and less established. It is important to note that only because women are outliving men does not mean they are living a better life. In fact, women tend to have shorter health spans, which means the number of healthy years in a person's life is less in women than men, confirmed Bérénice Benayoun, an associate professor at the U.S.C. Leonard Davis School of Gerontology.

As per a 2021 study titled, Sex differences in frailty: Comparisons between humans and preclinical models, found that women are more physically grail than men in old age. They are also more vulnerable, especially after menopause and are at more risk of developing cardiovascular issues and Alzheimer's disease because of age.

The key is in figuring out what makes one sex more resilient or vulnerable.

Genetics

For things which do not find easy explanations, scientists look for their answers in genes. Many research, including a 2020 study titled, The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life, suggests that the XX set of female sex chromosomes may impact longevity. However, there has not been any clarity on how it affects longevity.

Another 2018 study titled, Female XX sex chromosomes increase survival and extend lifespan in aging mice, which was conducted by Dr Dubal's lab, looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. It was found that those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

"There was something about the second X chromosome that was protecting the mice from dying earlier in life, even if they had testes. What if there was something on that second X chromosome that was in some ways a sprinkle of the fountain of youth," says Dr Dubal. While scientists have not yet looked at this factor in humans, Dr Dubal suggests that humans have the same hormones and sex chromosomes, and similar reproductive system that could corroborate the similar findings in people.

Hormones

Plenty research has shown that estrogen is responsible for longevity also effect on the immune system. The data also shows that before menopause, the female immune system tends to do better. In fact Dr Benayoun said that males tend to do much worse in response to infection.

Another 2017 study titled, Ages at Menarche and Menopause and Reproductive Lifespan As Predictors of Exceptional Longevity in Women: The Women's Health Initiative, found that women who experienced menopause later in life over the age 50 lived longer than those who experienced it earlier.

Lifestyle and Behavior

There are also disparity in behavioral patterns between men and women. This includes smoking, drinking heavily, which can contribute significantly to mortality. Women also have more "health promoting behavior", believe experts. Women are also more likely to socialize than men and thus it protects them from detrimental effects of social isolation and loneliness. In fact, a 2023 analysis published in Jama Network, titled, Widening Gender Gap in Life Expectancy in the US, 2010-2021, found that women are less likely to die by drug overdose or suicide.

Fatty liver disease, as a term, has been used for several years to describe a state of excess fat accumulation in the liver. However, the perception is changing—once known as non-alcoholic fatty liver disease (NAFLD), the condition is now referred to as metabolic dysfunction-associated steatotic liver disease (MASLD). The new term, according to leading diabetologist Dr V Mohan, offers more clarity because fatty liver is often associated with alcohol intake. However, even people who do not drink alcohol can develop this condition, and it has a metabolic angle to it. Despite the new name, the concern around fatty liver disease remains the same—can it be reversed?

Can MASLD be reversed?

In an interview with Health and Me, Dr Tushar Madake, consultant in the Department of Transplant Hepatology at Ruby Hall Clinic in Pune, spoke about the new name for fatty liver disease and why the metabolic angle is important.

Fatty liver disease may have a new name, but the concern around it has not changed. The current medical nomenclature identifies this as steatotic liver disease (SLD), with the previously identified NAFLD referred to as metabolic dysfunction–associated steatotic liver disease (MASLD). This classification places emphasis on the true source of the disease—metabolic health—and not necessarily alcohol intake.

Symptoms and diagnosis of MASLD

One of the reasons why fatty liver disease is challenging to diagnose is the fact that it does not exhibit noticeable symptoms in its early stages. The organ functions without issues, and individuals might not suspect a problem. Unlike common assumptions, this condition affects people who are not necessarily overweight or who consume alcohol.

Some of the early symptoms include constant fatigue, an increase in abdominal fat storage, and a feeling of heaviness in the upper right quadrant of the abdomen. Changes in the skin, such as discolouration around the neck and armpits and skin tag development, can also be among the symptoms of the condition. Individually, these signs do not necessarily indicate any cause for concern. However, when present together with metabolic issues such as type 2 diabetes, obesity, high levels of cholesterol, and high blood pressure, they might signify liver impairment in the early stages.

Therefore, early diagnosis and monitoring are crucial. If you have these risk factors or experience these symptoms, it is recommended that you undergo tests for liver dysfunction and ultrasonography. In some cases, you may also need to undergo a scan, for instance, a FibroScan, for early detection of liver fibrosis.

Reversing MASLD is possible

Dr V Mohan, one of India’s leading diabetologists, said, “The encouraging news is that early-stage fatty liver is not a permanent condition. With consistent lifestyle changes, reversal is possible. Weight loss, regular physical activity, reduced intake of refined carbohydrates and fats, and higher protein consumption can all contribute to improved liver health.”

Many people follow what appears to be a reasonable eating pattern—meals at irregular hours, a light breakfast skipped in the name of time, and dinner pushed late into the evening. Yet the body, particularly the liver, does not respond well to such improvisation. What feels like a manageable routine on the surface can quietly accumulate into something more serious over months and years. The liver needs a consistent flow of nutrients to do its job, which includes managing blood sugar, breaking down fats, and supporting digestion. Long gaps between meals disrupt that rhythm.

Dr Babu U V, Director of R&D, Research & Development Centre, Himalaya Wellness Company, in an interview with Health and Me, spoke about the early symptoms of liver damage and explained how herbs can play a role in reversing it.

Symptoms of Early Liver Damage

Before most people realise that something is wrong with their liver, they may already be experiencing symptoms that indicate potential liver issues. These symptoms may include fatigue, bloating, digestive discomfort, or feeling heavy after eating. Most of the time, these signs are dismissed as minor concerns.

When these issues are ignored or go unnoticed, it becomes difficult to recognise that the liver may be weakened by stress and not functioning optimally. If these problems persist over time, fat can begin to accumulate in the liver, along with other types of metabolic imbalances throughout the body.

To restore balance in the body, small changes in daily habits can lead to significant improvements. For example, eating at regular intervals helps the body maintain a consistent metabolism. Similarly, having lighter dinners and avoiding late-night eating can support better digestion and metabolism of food.

Herbs That Strengthen Liver Health

Some herbs commonly used in Indian households and traditional medicine may help support the liver’s healing process, especially when it is under stress.

1. Bhumi Amla (Bhumyamalaki) has been used for centuries in traditional remedies for liver health. It supports the body’s natural detoxification processes and liver function.
2. Punarnava is another well-known herb that promotes both liver and kidney health. It is believed to help reduce inflammation and restore balance in the body.
3. Turmeric (Haldi), found in almost every Indian kitchen, has anti-inflammatory and antioxidant properties. It supports metabolism and helps the body respond to oxidative stress.
4. Chicory (Kasani) has long been associated with liver support. It helps the body manage toxin-related stress and supports overall liver function.

Each of these herbs works in different ways—some aid digestion, while others help neutralise free radicals and reduce oxidative stress—thereby supporting a healthier lifestyle.

The liver is highly resilient; however, it requires consistent care. An irregular dietary pattern may not affect the liver immediately, but over time it can have a significant impact. Paying attention to simple habits—such as when and how you eat—and choosing foods that support liver health can go a long way in maintaining optimal liver function over the long term.

World Liver Day 2026 is observed every year on April 19 to raise awareness of the importance of liver health, focusing on preventing diseases such as cirrhosis and fatty liver through healthy lifestyles.

The liver is a key organ that filters blood, breaks down food, stores energy, and keeps the human body in balance.

However, rising metabolic risk factors, including high blood sugar and obesity, are increasingly driving cases of metabolic dysfunction-associated steatotic liver disease (MASLD).

Nearly one-third of the global adult population today lives with MASLD, which can remain asymptomatic for years but turn into deadly scarring (fibrosis), cirrhosis (advanced fibrosis and loss of some of the liver function), or even liver cancer.

World Liver Day: Origin

The European Association for the Study of the Liver (EASL) launched World Liver Day in 2010. The day was established on April 19 to commemorate the EASL's founding in 1966.

World Liver Day 2026: Theme

This year, 2026, the World Liver Day theme is “Solid Habits, Strong Liver”. It emphasizes building consistent lifestyle habits, such as balanced diet, regular exercise, avoiding alcohol, and routine check-ups, to strengthen liver health and prevent diseases.

From filtering toxins to aiding in digestion and metabolism, the liver silently performs over 500 crucial functions in the body. The organ is also blessed with the ability to regenerate itself.

Yet data shows that 2 million lives worldwide are lost each year to liver disease. About 1.5 billion people suffer from chronic liver disease.

MASLD, formerly known as non-alcoholic fatty liver disease (NAFLD), has emerged as the most common liver condition worldwide. These patients suffer from either obesity, diabetes, metabolic syndrome, hypertension, or cholesterol problems.

According to a recent study published in The Lancet Gastroenterology & Hepatology journal, MASLD affected 1.3 billion people around the globe in 2023.

The alarming study estimates the numbers to further spike by over 38 percent to reach 1.8 billion cases by 2050, causing substantial health and economic impacts worldwide.

MASLD remains one of the most prevalent and rapidly growing liver conditions worldwide, with its prevalence marking a 143 percent increase between 1990 and 2023.

People with obesity, diabetes, central or abdominal fat, dyslipidemia, hypertension, and insulin resistance are more likely to have MASLD. Obesity is the strongest risk factor, with the likelihood rising steeply from overweight to severe obesity.

Other signs to watch for include

• persistent fatigue
• Digestive issues and bloating
• Unexplained weight gain or difficulty losing weight
• Skin changes

Everyday Habits That Harm The Liver

Certain lifestyle choices can accelerate liver damage, such as:

• Overeating processed or fried foods
• High sugar intake (soft drinks, sweets, desserts)
• Physical inactivity or prolonged sitting
• Ignoring health issues like diabetes or hypertension
• Crash dieting or taking unprescribed supplements.

How To Improve Liver Health?

Early screening and detection are key to prevent irreversible stages. Yet liver disease can be prevented with lifestyle changes such as:

• Eating a balanced diet with vegetables, fruits, whole grains, and lean protein
• Engaging in at least 30 minutes of exercise daily
• Staying hydrated to help the liver flush out toxins
• Avoiding alcohol and smoking
• Avoiding self-medication and unnecessary pills
• Getting routine health screenings.
