Nigeria Has a Liver Disease Crisis
Liver disease is a serious and growing public health problem in Nigeria, and it is overwhelmingly a disease of men. Nigeria has one of the highest rates of chronic Hepatitis B infection in the world — it is estimated that more than 1 in 10 Nigerians carries the hepatitis B virus, many of them infected at birth or in early childhood. The vast majority are unaware of their status. Hepatitis B silently inflames and scars the liver over 20 to 30 years, often producing no symptoms until the liver is severely damaged. In men who also drink heavily — which is more common than in women — this damage is accelerated. Liver cancer (hepatocellular carcinoma) arising from chronic hepatitis B cirrhosis is one of the most common cancers in Nigerian men, and it is almost always diagnosed at an inoperable stage.
The Three Main Causes in Nigerian Men
Hepatitis B is a viral infection spread through blood and body fluids — from mother to child during birth, through unsterile medical or dental equipment, through blood transfusions with unscreened blood, and through unprotected sex. In Nigeria, mother-to-child transmission at birth and childhood exposure through shared household items and unsterile injections in under-resourced health facilities account for much of the burden. The vaccine, given at birth and in the first few months of life, is highly effective — but many adults in Nigeria were never vaccinated and do not know their status. Alcohol-related liver disease progresses through stages: fatty liver, inflammation (alcoholic hepatitis), and finally cirrhosis — irreversible scarring. Heavy drinking over many years causes each of these progressively. The difficult reality is that by the time cirrhosis is diagnosed, significant irreversible damage has already been done. Non-alcoholic fatty liver disease (NAFLD) is driven by obesity, a high-sugar and high-fat diet, and insulin resistance — the same forces driving the diabetes epidemic in Nigeria. A man does not need to drink at all to develop significant liver disease if he is significantly overweight and eating a poor diet.
Signs That the Liver Is in Trouble
- Yellowing of the whites of the eyes and the skin (jaundice) — one of the most visible signs of liver disease
- Abdomen becoming progressively more swollen and distended as fluid accumulates inside (ascites)
- Persistent fatigue, weakness, and loss of appetite that have no other explanation
- Dark urine — the colour of strong tea or Coca-Cola
- Very pale or clay-coloured stools
- Itching all over the body without an obvious cause
- Easy bruising and slow bleeding from small cuts — the liver makes clotting factors
- Confusion, memory problems, or personality changes — in advanced liver disease this indicates hepatic encephalopathy, a medical emergency
- Important: most chronic liver disease causes NO symptoms until the damage is very advanced — testing is the only way to catch it early
What Every Nigerian Man Should Know and Do
- Know your hepatitis B status — get tested. This is a single blood test that can change your life
- If you test negative, get vaccinated — the hepatitis B vaccine is a 3-dose series, is safe, and is available through government health facilities and private clinics
- If you test positive, see a doctor for regular liver function monitoring and assessment — not for managing the disease yourself
- Reduce or eliminate alcohol — the more you drink and the longer you drink, the more damage accumulates in the liver, and some of that damage is irreversible
- Maintain a healthy weight — a diet lower in processed foods and sugar and higher in vegetables, legumes, and whole grains protects the liver
- Ensure any injections, dental procedures, or medical procedures are performed with sterile equipment
- Do not share razors, toothbrushes, or nail clippers — these can transmit hepatitis B
