Liver disease often goes unnoticed in people with type 2 diabetes, PgII

Key Highlights:

• A European study in The Lancet found that 4.6% of adults have significant undiagnosed liver stiffness, and 1.6% have confirmed cases of liver fibrosis.
• Type 2 diabetes is strongly linked to fatty liver disease, accounting for over 90% of cases, often exacerbated by obesity and harmful alcohol use.
• Liver disease in type 2 diabetes often goes unnoticed due to the liver's high functional reserve and lack of pain receptors, with symptoms appearing only in advanced stages.
• Early detection through routine screening, including liver function tests and FibroScan, is crucial for timely interventions and preventing advanced liver disease.

Detailed Insights:

• Insulin resistance in type 2 diabetes disrupts glucose, fat, and protein metabolism, leading to hepatic steatosis, where fat accumulates in the liver.
• While fat accumulation may be harmless in some, it can lead to steatohepatitis, progressing to fibrosis and cirrhosis; genetic predisposition also plays a role.
• Additional factors contributing to liver damage include high free fatty acids, glycated proteins, disturbances in gut microbiota, obesity, dyslipidaemia, and hypothyroidism.
• Fibrosis, not just fat accumulation, is the key determinant of long-term outcomes, potentially leading to cirrhosis, liver failure, and hepatocellular carcinoma.
• "Lean NASH," seen in developing countries, highlights that even non-overweight individuals can develop fatty liver due to genetics and visceral fat deposition.
• Screening is essential, as up to 35% of people with type 2 diabetes may have fibrosis without symptoms, detectable through liver function tests, FIB-4, and FibroScan.
• Early interventions include weight management, improved blood sugar and lipid control, and medications like pioglitazone or GLP-1 receptor agonists such as semaglutide.

Key Concepts Involved:

• Hepatic Steatosis: Accumulation of fat in the liver.
• Fibrosis: The thickening and scarring of liver tissue due to continuous inflammation.
• Cirrhosis: Advanced stage of liver disease where healthy liver tissue is replaced by scar tissue, leading to liver dysfunction.
