The Liver Doesn't Warn You: How Hepatitis B, Mouldy Grain, and Everyday Painkillers Damage It Silently.

 

"But I Felt Fine"

Kofi was 38. He worked long hours, ate what he considered an ordinary diet, and had not seen a doctor in years. There was no pain and no fever. Then a colleague said one afternoon, "Your eyes look yellow."

Within days, blood tests and a scan showed advanced liver damage that had been building for years. "I felt completely fine," he told the doctor. "How is this possible?"

The answer lies in how the liver is built, and in three exposures Kofi had never been warned about. (Kofi is an illustrative composite. His story reflects a pattern clinicians see often: people diagnosed late, with no earlier warning.)

Why the Liver Fails in Silence

The liver is the body's chemical processing plant. It filters toxins, alcohol, and drugs from the blood, makes bile to digest fat, stores glucose and vitamins, produces clotting proteins, and supports immune defence.

It does all of this without complaining, for two reasons.

It has no pain sensors in its working tissue. Pain appears only when the organ swells enough to stretch its outer capsule, felt as a dull heaviness under the right ribs. By then, disease is usually advanced.

It has enormous reserve. A liver can lose a large share of its working cells and still keep you alive and feeling normal. That is a strength, but it is also why problems stay hidden until the reserve runs out.

The slow path to liver failure

Stage	What is happening	Can it be reversed?
1. Inflammation	The liver is under repeated attack from a virus, toxin, alcohol, fat, or drugs	Often, if the cause is removed or treated
2. Fibrosis	Scar tissue begins replacing healthy cells	Frequently halted, sometimes partly reversed
3. Cirrhosis	Widespread scarring; the liver shrinks and hardens	Usually managed, not reversed
4. Complications	Fluid in the abdomen, internal bleeding, confusion, liver cancer	Needs specialist care

Stages 1 and 2 are where testing changes outcomes. That is why waiting for symptoms is the wrong strategy.

Three Silent Threats at a Glance

Threat	How it harms the liver	Who is most exposed
Hepatitis B	Years of viral inflammation lead to scarring and cancer	People infected at birth or in early childhood, often unaware
Aflatoxin	A mould toxin damages liver cell DNA	People who eat poorly stored maize and groundnuts
Painkiller and herbal misuse	Toxic by-products overwhelm the liver's defences	Self-medicators, regular drinkers, anyone stacking products

Threat 1: Hepatitis B, Acquired Early and Never Diagnosed

Hepatitis B virus (HBV) infects liver cells. It spreads through blood, unprotected sex, and from mother to child at birth or in early childhood.

Age at infection decides the outcome. According to WHO, adults who catch hepatitis B develop chronic infection in fewer than 5% of cases, but infection in infancy or early childhood becomes chronic in about 95%. A baby's immune system does not recognise the virus as a threat, so it settles in for life.

Ghana's burden is high, but falling.

• A systematic review of 30 studies across all ten regions put national prevalence at 12.3%, with the highest rates in people aged 16 to 39.
• Within that review, prevalence fell steadily over time: 17.3% in studies from 1995 to 2002, 14.7% from 2003 to 2009, and 10.2% from 2010 to 2015.
• A later review (2015 to 2019) found 8.36% in adults but only 0.55% in children under five, strong evidence that childhood vaccination is working.

A typical scenario. A man born before routine infant vaccination may have been infected by his mother at birth. He grows up healthy, plays football, works, and raises a family. For 20 to 30 years the virus quietly inflames his liver. His first symptom may be yellow eyes or, in the worst case, liver cancer.

Myths and facts

• Myth: "I can catch it from a shared plate or a handshake." Fact: Hepatitis B is not spread by sharing food, handshakes, hugging, or sitting together.
• Myth: "If I felt sick with jaundice once, I would know." Fact: Most chronic infections have no symptoms for decades.
• Myth: "A positive result means a death sentence." Fact: Many people live long, healthy lives with monitoring and, when indicated, treatment.

Threat 2: Aflatoxin, the Poison in the Store Room

Aflatoxins are produced by Aspergillus moulds that grow on maize and groundnuts dried poorly or stored in warm, humid conditions. The International Agency for Research on Cancer classifies naturally occurring aflatoxins as Group 1 human carcinogens. A recent synthesis of studies from Ghana and Nigeria identified maize and groundnuts as the dominant dietary routes of exposure.

What it does inside the body. Liver enzymes convert aflatoxin B1 into a reactive compound that binds to DNA and can damage genes that normally suppress tumours.

Why hepatitis B makes it worse. The two risks multiply rather than simply add. Risk assessments estimate that liver cancer risk in people with both chronic hepatitis B and aflatoxin exposure may be up to 30 times that of people exposed to aflatoxin alone. Ghana's liver cancer rate, about 16 per 100,000 people, is among the highest in Africa, and researchers point to this combination as a likely contributor.

A typical scenario. Groundnuts are bought in bulk from a sack at the market and kept for months in a warm store room. Some are shrivelled, dark, or musty, but nobody sorts them out. They are ground into paste for soups. Cooking does not reliably destroy aflatoxin, so it reaches the plate with every meal.

Threat 3: Painkillers and Herbal Mixtures

How paracetamol (acetaminophen) injures the liver. The liver converts a small share of each dose into a toxic by-product. Normally the antioxidant glutathione neutralises it. When doses are too high, or glutathione is depleted by regular heavy drinking, poor nutrition, or low body weight, the toxic by-product accumulates and kills liver cells.

Know the limits. Label limits for healthy adults are generally no more than 4 g (eight 500 mg tablets) in 24 hours. Lower limits apply to regular drinkers, people with liver disease, and underweight or malnourished adults.

Watch for hidden paracetamol. Many cold, flu, and "extra strength" products already contain it. Combining them with regular paracetamol can double the dose without you noticing.

Herbal products carry their own risk. Some plant preparations are directly toxic to the liver, and unregulated mixtures vary in strength, purity, and contamination. "Natural" does not mean "liver-safe."

A typical scenario. After a week of body aches, a man takes paracetamol, then a cold-and-flu sachet, then a "strong" pain tablet, and washes it down with a herbal bitter, sometimes after a few beers. He believes he is taking four different things. His liver is processing paracetamol several times over, while alcohol and herbs add to the load.

Reading the Warning Signs

Looking back, Kofi recalled symptoms he had blamed on stress. Each has a physical explanation.

Early or subtle signs

• Fatigue that rest does not fix: the liver is less efficient at processing nutrients and clearing toxins.
• Loss of appetite and bloating: reduced bile flow and inflammation disturb digestion.
• Dark urine, especially in the morning: excess bilirubin, a pigment the liver normally clears, spills into the urine.
• Fullness under the right ribs: the liver capsule is stretching.
• Yellow eyes or skin (jaundice): bilirubin builds up in the blood.

Later signs that need urgent care

• Pale, clay-coloured stools: bile is not reaching the gut.
• Itchy skin with no rash: bile salts accumulate under the skin.
• Swollen legs, ankles, or abdomen: low albumin and raised pressure in the liver's blood vessels.
• Easy bruising or bleeding: clotting proteins are no longer being made.
• Vomiting blood or black stools: swollen, fragile veins in the gullet or stomach are bleeding.
• Confusion, unusual sleepiness, or personality change: toxins such as ammonia are reaching the brain (hepatic encephalopathy).

Vomiting blood, black stools, or sudden confusion are emergencies. Go to a hospital immediately.

What Happened Next

Kofi's doctors confirmed hepatitis B as the main driver and found that his food storage habits and self-medication had added to the damage. He started antiviral treatment, stopped the herbal mixtures and unsupervised painkillers, changed how he bought and stored food, and began regular monitoring. His liver stabilised.

Not everyone is treated the same way. WHO notes that chronic hepatitis B can be treated with oral antivirals such as tenofovir or entecavir, and that under its 2024 guidelines more than half of people with chronic infection may need treatment, depending on setting and eligibility. Others are monitored with periodic blood tests and scans. Only testing and a clinician's assessment can tell which group you belong to.

One rule for anyone on treatment: do not stop hepatitis B medication on your own. Stopping abruptly can trigger a dangerous flare of liver inflammation, so changes should always be supervised by a doctor.

What Your Hepatitis B Test Result Means

The screening test detects hepatitis B surface antigen (HBsAg). A fuller panel adds antibody tests. In general:

• HBsAg positive: you currently carry the virus. See a doctor for further tests and a monitoring plan.
• HBsAg negative, surface antibody positive: you are immune, through vaccination or past recovery.
• All markers negative: you have no protection, so get vaccinated.

Your doctor will interpret the complete pattern, including liver enzymes (ALT, AST) and, where relevant, viral load and ultrasound.

Your Seven-Day Action Plan

Day 1: Book a hepatitis B test. If negative and unvaccinated, start the vaccine series, typically three doses over about six months.

Day 2: Test your household. If you are positive, your partner and children should be tested and vaccinated. All pregnant women should be screened so that newborns are protected from birth. WHO recommends that all infants receive the vaccine, with the first dose at birth.

Day 3: Inspect your food store.

• Discard groundnuts and grains that are shriveled, mouldy, discoloured, or musty-smelling
• Dry crops fully and keep them off the floor in ventilated containers
• Buy smaller quantities, especially in the rainy season
• Never "salvage" mouldy food by cooking it or picking off visible mould

Day 4: Audit your medicine cabinet. Check every label for "paracetamol" or "acetaminophen." Never combine products that contain it. Avoid it after heavy drinking, and ask a pharmacist for a safer plan if you drink regularly.

Day 5: Review herbal products. Tell your doctor or pharmacist everything you take, and check that products carry Food and Drugs Authority registration. Stop any product and seek care if you develop yellow eyes, dark urine, or persistent nausea.

Day 6: Review alcohol and weight. Liver risk rises with the amount and frequency of drinking, and anyone with hepatitis B or known liver disease is generally advised to avoid alcohol entirely. Excess fat can also accumulate in the liver, a condition now called metabolic dysfunction-associated steatotic liver disease (MASLD), formerly fatty liver. It is driven by excess weight, sugary drinks, heavily processed food, inactivity, and diabetes.

Day 7: Ask for a liver function test. Routine enzyme tests can reveal liver inflammation before symptoms appear. If you have chronic hepatitis B, ask about regular ultrasound scans and blood tests, which are how liver cancer is caught while it can still be treated. Hepatitis C is also worth asking about: it is another silent cause of liver damage, and unlike hepatitis B it can be cured with treatment.

Who Should Be Especially Careful

• Anyone who has never been tested for hepatitis B
• People born before routine infant vaccination
• Children of mothers who carry hepatitis B
• Regular drinkers
• People who frequently use painkillers or herbal remedies
• People who regularly eat stored groundnuts and grains
• People with diabetes, obesity, or a family history of liver disease

Frequently Asked Questions

Can I have liver damage with normal-looking skin and eyes?
Yes. Jaundice is a late sign. Significant scarring can exist long before it appears.

If I was vaccinated as a child, am I protected?
Vaccination gives strong protection for most people. If you are unsure whether you completed the series, a blood test can confirm your immunity.

Is liver damage from hepatitis B always permanent?
No. Early inflammation and scarring can often be halted, and sometimes partly reversed, when the virus is controlled. Advanced cirrhosis is harder to reverse.

Does cooking remove aflatoxin from groundnuts or maize?
Not reliably. Prevention depends on proper drying, storage, and discarding suspect grain.

The Takeaway

"I thought I was healthy because I felt healthy," Kofi says. "But feeling fine and being fine are not the same thing. Your liver won't warn you. You have to go and check."

You do not need to wait for yellow eyes. One blood test, one vaccine series, and a few changes in how you buy, store, and take things can protect the organ that has worked for you every second of your life.

Key Takeaways

• The liver has almost no pain sensors and large reserve capacity, so serious disease can exist while you feel completely well.
• In Ghana, hepatitis B is one of the most important causes. Infection in infancy or early childhood becomes lifelong in about 95% of cases.
• Aflatoxin, a toxin from mould on maize and groundnuts, is a Group 1 human carcinogen and sharply raises liver cancer risk when combined with hepatitis B.
• Paracetamol is safe at the right dose but can destroy liver cells when doses stack up, especially with alcohol.
• One blood test and, if needed, a vaccine series can protect you. Waiting for symptoms is the riskiest strategy.
