MASLD/MASH -metabolic dysfunction -associated steatotic liver disease: What You Need to Know

MASLD is a silent but important marker of metabolic health and another consequence of raised Visceral Adipose Tissue (VAT). Although often discovered by chance, it carries significant implications for both liver and cardiovascular wellbeing. Through caloric restriction, physical activity, improved nutrition, and early intervention, MASLD can usualy be stabilised or reversed — protecting not just the liver, but the heart as well.

Cholesterol, LDL, and what we learnt from PCSK9 mutations in familial hypercholesterolaemia

PCSK9 binds to LDL receptors and directs them to be destroyed within the cell, rather than allowing them to recycle to the surface. When too much PCSK9 is present, fewer LDL receptors remain available to clear LDL from the blood. The result is simple: LDL levels rise. When that happens, the liver compensates by making even more cholesterol internally. This is why around 90% of the cholesterol in your blood is made by your liver, not absorbed from your diet.

PCSK9, visceral fat, and the modern metabolic environment

Because cholesterol is a fat-like substance, it cannot dissolve or travel freely in blood, which is mostly water. To move around, it must be packaged into microscopic transport particles called lipoproteins. One of these, LDL (low-density lipoprotein), acts as the main delivery vehicle, carrying cholesterol from the liver to cells that need it for repair or hormone production. In small amounts, LDL cholesterol is therefore completely normal and necessary. The problem only begins when too much LDL remains circulating in the blood for too long.
