INSIGHTS ON THE ISSUE

Context

Health:(WHO)

  • A certain totality of health to the realms of mental and social well-being and happiness beyond physical fitness, and an absence of disease and disability.
  • We cannot achieve health in its wider definition without addressing health determinants.

 

Non-communicable Diseases(NCD’s):

Liver diseases:

  • They are predominantly associated with excessive alcohol use and this remains an important cause of advanced chronic liver disease.
  • The emergence of a silently growing threat to liver health — non-alcoholic fatty liver disease.
  • Fatty liver is closely linked to metabolic health, cardiac health, and a risk for developing cancers.
  • This disorder has been reclassified and is known as ‘Metabolic dysfunction-associated steatotic liver disease’ (MASLD).
  • It has resulted in a paradigm shift in how we approach liver health.
    • The key is to screen, test, and treat.

 

Fatty liver disease:

Liver diseases
Liver diseases

●      MASH (Metabolic dysfunction-associated steatohepatitis), a progressive form that causes liver inflammation and scarring

○      It is expected to become the most common cause of chronic liver disease and the leading indication for liver transplantation.

○      The global prevalence of MASLD is estimated at 25-30%.

●      Meta-analysis(2022): It revealed that in India, among adults, the pooled prevalence of fatty liver was 38.6%, while among obese children, it was around 36%.

  • There is a close link between fatty liver disease and metabolic syndrome, including obesity, diabetes, high blood pressure, and abnormal cholesterol levels.
  • Individuals with these conditions have high MASLD prevalence rates:
    • 5%-59.7% for diabetes
    • 6%-95% for obesity
    • 73% for severe metabolic syndrome.

Fatty liver and metabolic syndrome:

  • Consuming excessive carbohydrates, especially refined carbs and sugars, worsens these conditions by causing metabolic problems.
  • When the body has too much glucose, it increases insulin production to help cells absorb the glucose.
  • Constantly eating too many carbs causes persistently high insulin levels, leading to insulin resistance, where cells become less responsive to insulin.
  • Insulin resistance disrupts normal metabolism and promotes the conversion of excess glucose into fatty acids, which are then stored in the liver.
  • The liver cells fill up with fat, leading to fatty liver.
  • Over time, this continuous damage affects the liver’s ability to function properly
    • progressing from simple fatty liver to more severe conditions such as steatohepatitis and cirrhosis, which are hallmarks of MASLD, and may require a liver transplant.

Issues:

  • Despite this growing burden of fatty liver disease, it often goes undetected as there is usually no warning or symptom in the early stages.
  • Diagnosis is usually made at an advanced stage, often when significant liver damage has already occurred.

 

What steps need to be taken?

  • A comprehensive health screening that includes a thorough history, physical examination, blood tests, and an ultrasound of the abdomen.
  • Physical examination will include height, weight, body mass index (BMI), abdominal girth, and waist-to-hip ratio to assess visceral fat.
  • Blood tests to cover cardio-metabolic risk factors include a blood count, sugar profile, blood lipid profile, liver function tests, and kidney tests.
  • An ultrasound of the abdomen is an important test to screen for liver disease and an important first step to diagnose fatty liver.
    • It is often missed or not included in many health checks, because of the limited availability of radiologists as well as stringent regulatory approvals.
  • Advanced liver tests will include liver fibrosis assessment to look for liver scarring
    • most accurately done by using newer technologies such as vibration-controlled transient elastography.
    • This is a non-invasive tool and it measures liver stiffness to assess early stages of liver fibrosis.
    • It can be used to regularly monitor the progression and responses to treatment.
    • ultrasound, comprehensive metabolic screening, and elastography — form an integrated approach to effectively detect and manage liver diseases at an early stage.

Case study:

  • In a cohort of 50,000 people screened at Apollo Hospitals:
    • Amongst the 33% that had fatty liver, as observed using an ultrasound of the abdomen
    • only one in 3 had elevated liver enzymes in their blood test.

 

Way Forward

  • The selection of screening tests and the frequency with which they are performed should be personalized.
    • This decision should be based on factors including an individual’s risk factors such as family history, lifestyle, and pre-existing health conditions.
  • Clinicians should not make generic assumptions given the patient’s age or physical markers alone.
    • We are increasingly witnessing non-communicable diseases break traditional stereotypes and impact very diverse people, including children.
  • Multiple factors affect liver health, necessitating integrated strategies that combine dietary modifications, regular physical activity, and effective weight management to mitigate liver disease risks.
  • The liver is a ‘silent organ’ that typically does not exhibit noticeable signs of damage until it reaches an advanced stage.
    • It is important that we are aware of the impact our lifestyle choices make in the long run.
  • We need to take active control of our health, be aware of what we consume, and go for frequent screenings because the groundwork for a happy life begins with good health.
  • To guarantee that everyone may live a healthy life, attaining health equity necessitates a comprehensive strategy that goes beyond legislative reform to address the socioeconomic determinants of health.
