How to look after your liver

How to prevent liver cancer

Last year, a survey by the British Liver Trust revealed that half of UK adults are unaware of many of the factors that can increase their risk of liver cancer. סרטן כבד ראשוני is cancer that starts in your liver, rather than spreading there from another part of your body. Also known as hepatocellular carcinoma (HCC), it's the fastest growing cause of סרטן death in the UK.

Sadly, due to late diagnosis, only 13% of people with the disease will survive for more than five years. In the same survey, almost 9 in 10 people thought the figure was much higher than this.

In the last decade, liver cancer has increased by almost two thirds in the UK. It's becoming more common at all ages and is now the 9th most common cause of cancer death. It's usually linked to cirrhosis - advanced liver disease which leads to permanent scarring of the liver, and sometimes liver failure. Fortunately, 90% of liver disease is preventable - with healthy lifestyle changes and a knowledge of your risks, you can help protect yourself.

Building on this survey, the British Liver Trust has launched a 'Love your liver' campaign. It highlights three key steps you can use to reduce the risk of liver cancer: alcohol, lifestyle and infectious hepatitis.

Your כבד is one of your busiest organs. It produces glucose, amino acids (the building blocks of proteins), hormones and bile, which helps your digestive system break down fats. But that's just a start. It also breaks down hormones we don't need, a variety of waste products and toxins, including alcohol.

Alcohol is a toxin - your liver can cope with so much without damage, and for a while your liver can regenerate if you stop drinking, even if it's been damaged. It's worth pointing out that the same does not apply to some of the other effects of alcohol on your body. For instance, there's no 'safe' limit for drinking where breast cancer is concerned - for every unit of alcohol you drink daily, your risk of סרטן השד increases by 7-10% compared to someone who doesn't drink at all.

But back to your liver - depending on how much you drink and for how long, your liver can develop fatty deposits which prevent it from working efficiently. This leads to inflammation (hepatitis) and finally irreversible scarring, called cirrhosis.

How to maintain a healthy liver and drink alcohol

For the sake of your liver as well as many other parts of your body, stick within the recommended limits for alcohol. That's not more than 14 units a week for men and women (a unit is about half a pint of normal strength beer or lager or a single pub measure of spirits. A 'standard' wine bar glass of wine contains about 2.3 units). You should also spread your alcohol intake over the week and have at least a couple - ideally three - alcohol-free days every week. Pregnant women should avoid alcohol completely.

If you want to protect your liver, look at your lifestyle. Your liver would love a diet with lower intake of sugar, refined carbohydrates (white bread and white flour products, white pasta, cakes and pastries) and saturated (animal) fat, which can reduce your risk of liver cancer.

How to maintain a healthy liver through your diet

Instead, fill up on veg, fruit, pulses and unrefined (wholegrain and wholemeal) carbs to maintain a healthy liver. In addition, take פעילות גופנית סדירה - aim to build up to half an hour a day, five times a week of the sort of exercise that makes you breathe a bit harder and gets your heart pumping.

Since travel opened up after a long hiatus due to the COVID-19 pandemic, many of us are desperate to get away on a foreign adventure. But in many countries the risk of viral hepatitis is higher than it is in the UK.

• הפטיטיס A, also known as 'infectious hepatitis', is very easy to catch from eating or drinking contaminated food or drink. It usually doesn't cause long-term problems, but it can make you feel very unwell for up to six months.

• הפטיטיס B ו hepatitis C are caught through sharing bodily fluids - unprotected sex or, in some cases, contaminated blood. Both of these can increase your risk of liver cancer. There's no vaccination available against hepatitis C, although if it's diagnosed in time it can often be cured with treatment. Hepatitis B can't be cured, and over time can increase your risk of cirrhosis and liver cancer. If you are at high risk, speak to your practice nurse about hepatitis B vaccination.

A healthy diet will also help you to keep your weight within recommended limits. Fatty liver used to be caused primarily by alcohol in the UK. However, as our nation's average weight has increased, so has the number of people with non-alcoholic fatty liver disease, (NAFLD) - it's thought as many as 1 in 3-5 people in the UK have NAFLD. Over time, these fatty deposits can make your liver stiff and scarred. This in turn makes it less able to get rid of toxins and can lead to serious health problems.

Some medicines can cause inflammation of the liver. If your doctor advises you to have regular checks, keep your appointment!

Sometimes genetics plays a part. Some liver diseases, including מחלת וילסון ו המוכרומטוזיס, are inherited.

A tendency to fatty liver disease can run in families. Type 2 diabetes is also a risk factor for liver disease - although being overweight may be the common link here.

But whatever the cause, maintaining a healthy weight will help protect you against fatty liver and other liver damage. Even more importantly, your liver is remarkably forgiving. By improving your diet, alcohol intake and exercise and cutting your weight if you're overweight, you can often reverse fatty liver, putting it back into tip-top shape.
