How to look after your liver

The liver is a vital organ responsible for filtering toxins, metabolising nutrients, storing energy, and producing bile for digestion. Looking after your liver is therefore essential for health and wellbeing.

Mr Shahid Farid, highly accomplished consultant general, hepatobiliary and liver transplant surgeon, explains how diet, exercise, and lifestyle choices impact liver health, as well as whether liver damage can be reversed and the signs to watch for when it comes to liver problems.

How does diet influence liver health?

The food you consume has a direct impact on liver function. A diet rich in fruits, vegetables, lean proteins, and whole grains provides the essential vitamins and minerals the liver needs to perform its many tasks efficiently.

For example, antioxidants found in berries, broccoli, and leafy greens reduce inflammation and protect liver cells from damage caused by oxidative stress. Omega-3 fatty acids in foods like fish and nuts also have anti-inflammatory properties that benefit the liver.

Conversely, a diet high in saturated fats, refined sugars, and processed foods can lead to the accumulation of fat in the liver, increasing the risk of fatty liver disease. Similarly, excessive alcohol can also severely damage liver cells, leading to conditions like alcohol-related liver disease, fibrosis, or cirrhosis.

Staying hydrated is another crucial aspect of liver health. Water helps flush out toxins and supports the liver's filtration system. For this reason, it’s important to avoid sugary beverages and opt for water or herbal teas to maintain hydration.

What is the role of exercise in preventing liver disease?

Regular physical activity helps regulate body weight, reducing the likelihood of obesity and metabolic syndrome, which are significant risk factors for fatty liver disease. Excess body fat, especially around the abdomen, can lead to fat deposits in the liver, impairing its ability to function properly.

Aerobic exercises, such as running, cycling, or swimming improve cardiovascular health and enhance the liver’s ability to metabolise fats. Resistance training, such as weightlifting, can also help by improving muscle mass and reducing insulin resistance, which is associated with liver disease.

Exercise also has the added benefit of promoting better circulation, which reduces inflammation and supports liver repair. Practising at least 150 minutes of moderate exercise per week is recommended for most people to maintain liver health.

How do lifestyle habits affect the liver?

Beyond diet and exercise, other lifestyle habits significantly impact liver health. Smoking, for example, exposes the body to harmful toxins that increase oxidative stress on the liver, increasing the risk of liver damage and cancer. Similarly, substance misuse or excessive use of medications can put additional strain on the liver as it works to detoxify these substances.

Chronic stress can also indirectly harm the liver by disrupting normal hormonal balances and leading to unhealthy coping mechanisms, such as overeating, smoking, or drinking. Stress management techniques like mindfulness, yoga, or deep breathing can help to manage stress and also support liver health.

Moreover, it’s essential to be careful about exposure to environmental toxins. Pesticides, cleaning products, and certain industrial chemicals can enter the body and harm the liver. Using protective gear, washing hands, and opting for non-toxic products are recommended.

Can liver damage be reversed?

The liver has a remarkable ability to regenerate itself, but the extent to which damage can be reversed depends on the severity of the condition. Early-stage liver damage, such as that caused by fatty liver disease or mild alcohol-related damage, can often be reversed through lifestyle changes.

However, advanced liver damage, such as cirrhosis, is generally irreversible. Cirrhosis involves significant scarring of liver tissue, which hinders the liver’s ability to regenerate and function. Treatment for cirrhosis focuses instead on slowing its progression and managing symptoms.

Recognising the early signs of liver problems is crucial for timely intervention. Symptoms include fatigue and weakness, jaundice, swelling in the abdomen or legs, dark urine and pale stools, persistent nausea or vomiting, loss of appetite, and unexplained weight loss.

If you notice any signs of liver issues, it’s important to seek medical attention promptly. Early diagnosis and treatment can help prevent further damage and improve outcomes.
