The 28th of July is World Hepatitis Day, reminding healthcare practitioners (HCPs) and patients alike of the importance of liver health. Every day, more than 3 600 people die of viral hepatitis-related liver disease, liver failure and liver cancer.1
Unfortunately, liver health in Africa has been understudied, causing diseases such as hepatitis, liver cancer, liver cirrhosis and non-alcoholic fatty liver disease (NAFLD) to go undetected and therefore somewhat neglected.1
In Africa, dying from viral hepatitis is becoming more of a danger than dying from HIV/AIDS, malaria or tuberculosis. 1 Chronic viral hepatitis affects over 70 million Africans (60 million with hepatitis B and 10 million with hepatitis C).1
Despite the availability of diagnostic instruments and effective treatment, over 90% of people living with hepatitis B and C in Africa don’t have access to the care needed. 1 This means that prevention advice and education from HCPs become even more important in African populations.
Hepatocellular carcinoma (HCC) is the 6th most common cancer worldwide, 5th in males and 9th in females.2 HCC frequency and mortality are expected to increase in many African countries, especially those that are constrained by inadequate treatment resources and environmental risk factors.2

Cirrhosis-related deaths have doubled in sub-Saharan Africa from 1980 to 2010.3 In 2010, the Central African Republic, Gabon, Malawi, Uganda and Cote d’Ivoire were all found to be a part of the highest 10% of countries in which these deaths occurred.3
Liver cirrhosis treatment is inaccessible in most parts of sub-Saharan Africa. This is due to the massive shortage of hepatologists and gastroenterologists, interventional radiologists, hepatobiliary surgeons and pathologists.4
Non-alcoholic fatty liver disease (NAFLD)
The reported prevalence NAFLD in the general African population is likely to be an underestimate.5 The long-term impact of rising obesity and type 2 diabetes mellitus prevalence in Africa makes NAFLD a hidden danger in this region.5
Health authorities in African countries need to be aware of this silent threat and develop strategic responses to deal with it.5
What can African HCPs do about liver disease?
The good news is that the liver is one of the only organs in the body able to replace damaged tissue with new cells rather than scar tissue.1 HCPs can educate their patients on the symptoms, protection measures and treatment options of liver disease.
Teach your patients about the basics:
Easy-to-identify symptoms of an unhappy liver 6-7
- Chronic fatigue
- Weight loss
- Loss of appetite
- Pale, bloody or black stool colour
- Swelling in the ankles & legs
- Easy bruising
- Impaired brain function
- General failing health
Protecting liver health recommendations 8 -10
- Reduce intake of alcohol (if possible – don’t drink at all)
- Avoid the following foods:
- Red meat
- Trans fats
- Processed carbohydrate
- High-fructose corn syrup
- Fried foods
- Raw/undercooked shellfish
- Maintain a healthy body weight
- Exercise for 30 – 60 mins, 3 – 4 times a week (moderate intensity)
- Eat a balanced diet with fibre, through grains, fruits, vegetables, meat & legumes
- Drink lots of water (to prevent dehydration)
- Get vaccinated against hepatitis A & B
- If you have diabetes, aim to control your blood sugars
- To avoid getting hepatitis:
- Practice safe sex
- Do not share any personal items that may have blood on them, e.g., toothbrush; razor etc.
- Make sure that your consumables are clean
- Hepatitis A infections are often a result of poor cleanliness
It is strongly recommended that the patient be seen by a registered dietitian to support optimal nutrition.
Recommended eating habits, in the case of: 10
- Limit iron-dense foods
- Limit salt & foods with a lot of salt
- Limit salt & foods with a lot of salt
- Reduce protein intake
- Limit high-calorie foods
- Eat foods that have fibre
The importance of prevention
Treatment for liver disease varies according to the diagnosis. Some can be treated with lifestyle modifications and others with medical programmes or surgery.9 Yet, as one can see, many of the treatment options in Africa are inaccessible to the public.
In turn, prevention of liver diseases methods are much more effective than treatment methods. This is why HCPs should share preventative information on the topic with their patients.
