The liver doesn’t ask for much, but it does everything for you. It metabolizes nutrients, screens out poisons, synthesizes proteins, and aids in the digestion of your food. But when hepatitis strikes—a disease characterized by swelling of the liver—that whole system can become unbalanced. And the most likely culprits? The five viruses simply called hepatitis A, B, C, D, and E.

Each viral hepatitis type acts differently, transmits itself differently, and does its own kind of damage. Some resolve rapidly. Others lie dormant for years, silently harming the liver until it is too late. This makes learning about hepatitis—not as a disease but as a category of very different conditions—key to safeguarding long-term liver health.

When your liver becomes inflamed, it has difficulty doing its vital jobs—purifying your blood, making bile for digestion, storing nutrients, and helping to regulate clotting and metabolism. This inflammation may be acute (temporary) or chronic (longer than six months), depending on the cause and how your immune system reacts.

Hepatitis may be initiated by infections, toxins, autoimmune, or metabolic disorders, but the predominant offenders worldwide are viral infections. The viruses are segregated into hepatitis A through E, each with a different effect on liver cells and course of disease.

Hepatitis A

Hepatitis A is caused by the hepatitis A virus (HAV), usually spreading by food or water contamination. After entering the body, the virus takes the route of the bloodstream and reaches the liver. There, it infects liver cells and triggers the immune system to respond with inflammation.

This immune response results in the death of infected liver cells, and this can cause symptoms such as fatigue, jaundice, and gastrointestinal disturbance. Happily, HAV does not lead to chronic liver disease. The liver will normally regenerate completely after clearing the virus, and the majority of individuals recover in several weeks with no long-term effects.

All that being said, on occasion—most often in older individuals or individuals with existing liver disease—hepatitis A can result in acute liver failure. The liver gets so bogged down from inflammation that it temporarily ceases to function. Vaccination and proper sanitation are still the best defense.

Hepatitis B

Hepatitis B virus (HBV) is spread through blood, body fluids, or from mother to child at the time of birth. After entering the body, HBV infects liver cells and embeds its genetic material into them. The immune system destroys these infected cells, leading to extensive inflammation.

In most adults, the immune system eliminates the virus and the liver recovers. But not in all—particularly infants infected at birth—the virus persists. Chronic hepatitis B forms when the body's immune system fails to destroy the virus, resulting in prolonged inflammation and eventual loss of liver cells.

With time, this persistent immune attack can result in fibrosis (liver scarring), cirrhosis (severe, permanent scarring), and even liver cancer. What's particularly alarming is that chronic hepatitis B usually has no symptoms for decades. But below the radar, the virus quietly destroys liver tissue, cell by cell.

Vaccination prevents hepatitis B remarkably well, and antiviral medications can suppress the virus, stopping or slowing liver damage.

Hepatitis C

In contrast to HAV and HBV, hepatitis C virus (HCV) is transmitted nearly exclusively via the blood—usually through shared needles, untested transfusions (prior to 1992), or unsterilized medical procedures. Once infected by HCV, the liver starts to replicate the virus within liver cells, hiding from the immune system for years.

This sneaky virus hardly ever produces symptoms at the acute stage. Actually, most individuals don't even realize they are infected. But the liver doesn't remain unaffected. As HCV quietly multiplies, it causes low-grade inflammation that lasts for decades. The immune system acts against the infected cells, causing fibrosis.

Over time, chronic hepatitis C can lead to cirrhosis, in which scar tissue forms in place of healthy liver tissue. In later stages, the function of the liver declines, and the risk of liver failure and liver cancer accelerates. A liver transplant becomes the only recourse for many.

The better news? Direct-acting antiviral (DAA) treatments now cure greater than 95% of infections. Early diagnosis, however, is still important—once cirrhosis takes hold, the damage can be permanent, even once the virus is gone.

Hepatitis D

Hepatitis D, or HDV, is different from the others—it can't infect the liver by itself. It only exists in those already infected with hepatitis B, employing the outer shell of the HBV virus to replicate.

When HBV and HDV infect the liver concurrently (a co-infection) or if HDV is contracted later on superimposition of pre-existing HBV (a superinfection), the immune system is twice assaulted. The liver has to cope with more intense inflammation, resulting in more rapid fibrosis progression and much increased risk of cirrhosis and hepatocellular carcinoma.

In individuals with co-infection, liver injury is more severe, and complications arise years sooner than in HBV mono-infection. There are no specific therapies for HDV currently, and its management relies mostly on the control of hepatitis B.

It is also possible to prevent HBV infection and thereby hepatitis D by vaccination. Antiviral therapy and close follow-up can likewise decrease the chances of serious HDV complications in those already infected with HBV.

Hepatitis E

Hepatitis E virus (HEV) is transmitted primarily through water, which makes it prevalent in underdeveloped countries with inadequate sanitation. Upon entry into the body, it acts like HAV—producing an acute infection, liver inflammation, and a short duration of illness.

The vast majority of healthy individuals with hepatitis E recover uneventfully. The virus is naturally cleared, and the liver generally restores to normal completely. But in pregnant women, particularly in the third trimester, hepatitis E leads to acute liver failure and has a significantly increased risk of death. This is secondary to an overactive immune response and hormonal changes that exacerbate the liver's inflammatory process.

Hepatitis E can, in rare cases, become chronic, leading to long-term damage of the liver in some individuals, such as organ transplant recipients, especially those with weakened immune systems.

Prevention through clean water, sanitation, and hygiene and food safety is practiced in most countries where there are no widely available vaccines for hepatitis E.

What Are the Consequences of Chronic Hepatitis?

What links hepatitis B, C, and occasionally D is that they all have the potential to become chronic—i.e., the virus continues to cause liver inflammation over years or even decades. This ongoing low-grade inflammation leads to persistent scarring of liver tissue, called fibrosis.

As fibrosis progresses, it results in cirrhosis, with scar tissue dominating the liver, strangling its blood supply and function. The liver starts to fail. It is no longer able to process toxins, manufacture clotting factors, or metabolize drugs. Here, individuals are susceptible to internal bleeding, confusion, infections, and organ failure.

Even more concerning is the risk of hepatocellular carcinoma, a liver cancer primary to chronic hepatitis B and C. The chronic viral presence causes changes in DNA of liver cells, paving the way for malignant change.

What If Hepatitis Is Left Untreated?

Not treating hepatitis—especially the chronic stages—places you on a trajectory for irreversible liver damage. Even when you may not be feeling sick at present, inflammation can be quietly devouring your liver. Left untreated, this can culminate in lifelong disability, necessitate liver transplantation, or cut short lifespan from complications such as liver cancer.

In addition, untreated individuals can go on to infect others with hepatitis B or C by contact with blood or through sex. In pregnant women, hepatitis B and C can be transmitted to the unborn child at the time of delivery, which makes prevention and early treatment critical to the next generation.

Every year on July 28, World Hepatitis Day calls to mind that hepatitis remains a global health issue. More than 354 million individuals have chronic hepatitis B or C infection, unaware they are infected. It's not only an issue in low-income nations—people from all geographies and income groups are affected by hepatitis.

The date commemorates Nobel laureate scientist Dr. Baruch Blumberg, who discovered the hepatitis B virus and created the first vaccine. His legacy goes on saving millions of lives.

The World Health Organization's goal is ambitious, to eradicate viral hepatitis as a public health threat by 2030. But it begins with awareness, testing, vaccination, and access to life-saving treatment.

The liver is tough, but not forever. Once scarring sets in, there is no turning back. The sooner hepatitis is found, the better your chances of recovery and preventing long-term complications. With vaccines to prevent hepatitis A and B, and curative therapy for hepatitis C, the means are at hand.

If you’ve never been tested for hepatitis, especially if you’ve had a blood transfusion before the 90s, were born to an infected mother, or engaged in high-risk behaviors now is the time. Your liver’s future depends on it.

Ladies, does it ever happen to you that you are not on your period, not PMSing, and still feel moody and upset? Well, as it turns out, experts say that there could be a very simple reason for this. According to researchers at the University of Connecticut, even mild dehydration could be responsible for mood changes in women. Not only this, even 1.36 per cent dehydration can affect your mood, ability to think and energy levels. The Daily Mail notes that a loss of 1.5 per cent of normal water volume levels in the body can be classified as mild dehydration, and its adverse effects can linger for some time.

How does dehydration affect women?

In women, the adverse effects of dehydration can be serious. Experts say that the effects are more intense in women, and they came to this conclusion after analysing the results of tests, which revealed that it does not matter if a person walks for 40 minutes on a treadmill or is in a state of rest — if an individual is even slightly thirsty, the adverse effects will be the same.

Research shows that even 1.36 per cent dehydration is enough to cause the following problems:

1. 8 per cent rise in hostility and anger
2. 12 per cent dip in vigour
3. 17 per cent increase in fatigue
4. 45 per cent dip in concentration
5. 19 per cent worsening of mood
6. 58 per cent dip in understanding simple tasks
7. Headaches worsening two fold

Is thirst the same as dehydration?

Lead researcher of the study, Lawrence Armstrong, noted that a sensation of thirst does not appear until a person is one or two per cent dehydrated. By then, it starts to set in and act up, adversely impacting how the mind and body perform. Dehydration can affect everyone, which is why it is just as important for people in desk jobs to stay hydrated as it is for marathon runners.

In this research, experts put participants through a series of tests evaluating their concentration, vigilance, reaction time, reasoning, memory and learning. The results were then compared with those of people who were not dehydrated. In younger women, mild dehydration resulted in fatigue, headaches and concentration difficulties. Women also found basic tasks more difficult to execute than usual. On the other hand, young men noted some difficulty in performing mental tasks — they experienced anxiety, fatigue and tension in the process. Mood changes were more prominent in women than in men.

The oral microbiome is the community of bacteria, fungi, and other microorganisms that naturally live in the mouth — on the teeth, gums, tongue, and cheeks. More than

700 species are known to exist, most of which are harmless and many beneficial.

However, problems arise when harmful bacteria outnumber protective ones, leading to gum inflammation or periodontal disease. During pregnancy, hormonal changes increase blood flow to the gums and alter immune responses. As a result, many women notice bleeding, swelling, or sensitivity in the gums — a condition known as pregnancy gingivitis.

This is common and reflects physiological changes rather than poor hygiene.

The Mouth's Connection To The Placenta

Pregnancy is a systemic state in which the immune system, circulation, and inflammation are closely interconnected. Chronic gum inflammation can release inflammatory mediators into the bloodstream.

In research settings, certain oral bacteria have also been detected in placental tissues from complicated pregnancies. This suggests a biological link between oral health and

placental function, although the exact pathways are still being studied.

Importantly, this relationship reflects association rather than direct causation.

Why Does Placental Health Matter?

The placenta is an active organ that regulates oxygen and nutrient transfer, hormone production, and immune protection for the developing baby.

Healthy placental development supports:

• Efficient oxygen and nutrient delivery
• Balanced hormone production
• Protection against infections
• Steady fetal growth

What Changes In Oral Health Are Normal During Pregnancy?

Up to 60–75 percent of pregnant women experience some degree of gum inflammation. Common changes include:

• Bleeding while brushing
• Swollen or tender gums
• Increased plaque buildup
• Persistent bad breath

Can Oral Health Really Affect Pregnancy Outcomes?

Research from India and globally shows associations between periodontal disease and higher risks of preterm birth, low birth weight, and preeclampsia. Meta-analyses

suggest a modest increase in risk (around 1.5–2 times).

However, pregnancy complications are multifactorial. Oral disease alone does not directly cause these outcomes. Genetics, nutrition, metabolic health, and placental

biology all play important roles.

Treating gum disease improves oral health and reduces inflammation, though studies show mixed evidence on whether it directly lowers preterm birth risk. The goal is

prevention, awareness, and overall maternal health.

How Do You Support Healthy Oral Microbiome During Pregnancy?

Daily oral care:

• Brush twice daily with gentle pressure
• Use a soft-bristled toothbrush
• Clean between teeth once daily
• Rinse your mouth after vomiting to protect enamel

• Calcium-rich foods like curd and ragi support dental health
• Vitamin C from amla, guava, and citrus helps gum healing
• Fibre-rich foods support saliva flow and microbial balance
• Hydration and lifestyle
• Drink adequate water
• Limit frequent sugary snacks
• Avoid tobacco in all forms

Pregnancy already carries emotional and physical changes, and dental symptoms can add anxiety. Support from partners and family members helps reduce mental load.

Stress can influence immunity and inflammation. Adequate rest, gentle activity such as walking or prenatal yoga, and open communication with healthcare providers

support both oral and overall health.

Warning Signs: When Should You Contact A Doctor Or Dentist?

Seek professional advice if you notice:

• Severe tooth pain or swelling
• Pus, fever, or difficulty chewing
• Bad breath that does not improve
• Persistent gum bleeding for two weeks

Pregnancy is a time when different systems of the body work in close coordination. Oral health, immune balance, and placental function are part of the same continuum.

Gentle attention to gum health is not about perfection. It is about creating supportive conditions for a healthy pregnancy and a healthy baby.

Hormonal imbalance plays an important role in the development of endometrial cancer, which is one of the most common types of gynaecological cancers worldwide. The endometrium is the inner lining of the uterus and is highly sensitive to hormonal changes, particularly the balance between oestrogen and progesterone. When the body is exposed to excess oestrogen without adequate progesterone, the endometrial lining grows excessively. Over time, this prolonged stimulation leads to abnormal cell changes and increases the risk of developing endometrial cancer or uterine cancer.

How does lifestyle affect hormones?

Dr Fahad Afzal, Consultant Oncologist at Saifee Hospital, while talking about the impact of lifestyle on hormones, said, “Several lifestyle and health conditions can contribute to this hormonal imbalance. Obesity is one of the most significant risk factors because excess body fat increases oestrogen production. Women who are obese therefore have higher levels of oestrogen, which stimulates the uterine lining. Moreover, conditions like PCOS, diabetes, and metabolic syndrome are also associated with hormonal disturbances that elevate the risk.”

A sedentary lifestyle and an unhealthy diet further worsen hormonal imbalance and inflammation in the body. Additionally, irregular menstrual cycles, early onset of menstruation, late menopause, and not having children increase lifetime oestrogen exposure.

How to treat hormonal imbalances?

The encouraging aspect is that several of these risk factors are modifiable. Maintaining a healthy body weight, engaging in regular physical activity, and following a balanced diet help regulate these hormones and reduce the risks. Managing conditions like PCOS and diabetes with guidance from a trained medical professional is also important.

Equally important is awareness of symptoms. Any abnormal uterine bleeding or vaginal bleeding, especially after menopause, should never be ignored and requires prompt medical evaluation. Early detection of endometrial cancer often leads to good outcomes. Understanding the relationship between lifestyle, hormone balance, and cancer risk can help women take proactive steps towards prevention and timely diagnosis.

What is the impact of hormones on endometrial cancer?

Dr Smit Sheth, cancer physician at M|O|C Mulund, said, “Hormones play a crucial role in a woman’s reproductive health, but when they fall out of balance, they can also increase the risk of certain cancers, including endometrial cancer. Endometrial cancer, which affects the lining of the uterus, is one of the most common gynaecological cancers in India. According to World Health Organization data, its incidence is steadily rising, particularly in urban populations where lifestyle changes are more pronounced.”

At the core of this risk lies an imbalance between two key hormones: oestrogen and progesterone. When oestrogen levels remain high without adequate progesterone to counteract it, the uterine lining can grow excessively, increasing the chance of abnormal cell changes over time. Modern lifestyle factors are significantly contributing to this imbalance. Rising obesity rates, sedentary habits, delayed pregnancies, and conditions like polycystic ovary syndrome (PCOS) are increasingly common among Indian women.

Fat tissue itself produces oestrogen, meaning overweight women often have higher circulating levels of this hormone. Studies suggest that obese women may have up to 2–4 times higher risk of developing endometrial cancer compared to those with a healthy weight. Additionally, irregular menstrual cycles, early onset of menstruation, and late menopause further extend lifetime oestrogen exposure, compounding the risk.

“Lifestyle today is a major driver of hormonal imbalance,” explains Dr Smit Sheth, cancer physician at M|O|C Mulund. “Obesity, lack of physical activity, and unmanaged metabolic conditions can silently increase oestrogen levels. Over time, this creates a favourable environment for endometrial cancer to develop, especially if symptoms like abnormal bleeding are ignored.”

Can endometrial cancer be detected in time?

The good news is that endometrial cancer is often detectable early. Warning signs such as postmenopausal bleeding, irregular periods, or unusual discharge should never be overlooked. Simple lifestyle changes, maintaining a healthy weight, regular exercise, a balanced diet, and timely medical check-ups can significantly reduce risk. In a country like India, where awareness remains limited, early education and proactive health behaviour are key to prevention.
