Liver Function Tests (LFTs) check how well your liver is working and whether there’s any inflammation or damage. They include several different markers that give clues about liver health and overall body function.
LFTs are a group of blood tests that look at different enzymes, proteins, and waste products in your blood. They help detect liver inflammation, blockage, damage, or changes in how the liver is functioning.
When Levels are High
High levels can mean different things, depending on which markers are raised. Some common causes:
• Viral infections (like hepatitis)
• Alcohol-related liver stress
• Fatty liver or metabolic conditions eg ALT, GGT
• Gallbladder problems or blockages eg ALP, GGT
• Medication effects eg oral estrogens, cyproterone etc
• Muscle injury (for AST/ALT)
When Levels are Low
Some liver enzymes or proteins may be lower than expected, and in many cases, this is not a cause for concern. However, low results may reflect:
• Stress response (your body may suppress certain enzymes under acute or ongoing stress)
• Corticosteroid use (medications that blunt inflammation can reduce liver enzyme levels)
• Chronic liver disease (in advanced stages, the liver may stop producing enough of its usual enzymes and proteins)
➡️ If several levels are low—especially albumin or total protein—your doctor may look more closely at long-term liver function or nutritional status.

Understanding trends in the results
📈 Rising levels: May signal inflammation, medication effects, or early liver stress.
📉 Falling levels: Could reflect recovery—or in some cases, suppression from chronic stress, medications, or progressing liver dysfunction.
⚖️ Consistently low levels, especially with no symptoms, are often not worrisome—but patterns matter more than one-off results.

🔬 Liver Function Tests: A Deeper
Dive
Liver Function Tests (LFTs) are actually a group of different blood tests that tell us about various aspects of liver health—not just how well your liver is "functioning," but also whether there’s inflammation, blockage, or stress. Each marker reflects a slightly different process, which is why patterns matter more than any one number.
ALT
(alanine aminotransferase) and AST (aspartate aminotransferase)
are enzymes that live inside liver cells. When liver cells are irritated or injured—by medications, alcohol, fatty liver, or even viral infections—these enzymes can leak into the bloodstream. ALT is more liver-specific, while AST can also come from muscle tissue.
GGT (gamma-glutamyl transferase)
is often raised with alcohol use, medication effects, or bile flow issues. If it’s high alongside ALP, it points more toward the bile ducts or gallbladder.
ALP (alkaline phosphatase)
is found in the bile ducts and bones. High ALP may suggest a bile flow problem, like gallstones or inflammation.
Bilirubin
is a yellow pigment made when old red blood cells break down. If it builds up, it might cause jaundice (yellowing of skin or eyes), and can point to issues with bile flow or liver processing.
Albumin and total protein
give insight into how well the liver is making important proteins. Low levels might indicate chronic liver disease, inflammation, or poor nutritional absorption.
Because the liver plays so many roles—from hormone and toxin processing to protein and energy storage—LFTs offer valuable insight into overall body health. But they don’t give the full story on their own, and mild changes often need to be interpreted in context.
🌿 Liver Health and Rejuvena
tion
Your liver is one of the most resilient organs in the body—capable of repair, regeneration, and incredible recovery when given the right support. Everyday things like eating well, staying active, supporting your gut health, reducing alcohol, and managing stress can all promote liver repair. Even if your liver has been under pressure from hormones, medications, or life’s wear and tear, it often responds well to gentle, consistent care.
There’s no need for harsh detoxes or extreme diets. Instead, think of liver health as a long-term relationship: nourishment, rest, hydration, and hormone balance go a long way. And if your blood tests show a wobble? It’s not always a crisis—just a clue to check in with your body and offer it what it needs to thrive.
One of the most rewarding parts of my work is supporting women with metabolic liver conditions—especially when hormonal shifts, weight changes, or insulin resistance have taken a toll. I love seeing how LFTs improve alongside energy, mood, and overall wellbeing when we take a thoughtful, whole-body approach. More on this soon, including how to spot the signs and what really makes a difference.

🧪 Raised ALT and Fatty Liver – What Does It Mean?
Your recent blood test showed a mildly raised ALT (alanine aminotransferase) level. ALT is an enzyme found in liver cells — and when it's slightly elevated, it often points to mild liver irritation.
One of the most common reasons for this is a condition called fatty liver, or hepatic steatosis. This means there’s a build-up of fat in your liver cells, often without any symptoms.
✅ What you need to know:
It’s common – fatty liver affects about 1 in 3 adults, especially if there’s insulin resistance, weight gain around the middle, or a history of high cholesterol, diabetes, or PCOS.
Often reversible – with changes to diet, movement, and metabolic health, liver fat and ALT levels can improve.
No need to panic – a mildly raised ALT doesn’t mean liver failure or permanent damage, but it’s a helpful early flag.
🧭 What happens next?
We might:
Check other liver markers and repeat the test in a few months.
Talk about your metabolic health (e.g. blood sugar, cholesterol, waist circumference).
Look at nutrition, alcohol, physical activity, and stress, all of which can affect liver health.
In some cases, recommend an ultrasound scan if needed.
❤️ What you can do to support your liver:
Focus on whole, unprocessed foods – especially leafy greens, nuts, olive oil, and good-quality protein
Reduce added sugars and refined carbs
Aim for regular movement – walking, strength training, and reducing long sitting periods all help
If you drink alcohol, consider cutting back or taking regular breaks
Review medications or supplements that may affect the liver
✨ The good news?
Your liver is incredibly resilient — and this is a chance to support it early. Many people see improvements in ALT and overall health with just a few consistent changes.
Let’s keep an eye on it together and take small, doable steps toward better liver health.
