Kidney disease is a silent killer

How much do you know about your kidneys? Our kidneys act as internal filters, assisting in the removal of waste and fluids from our bodies through our urine. Kidneys are designed to balance salts and acids within the body and produce hormones and enzymes to control blood pressure and control the production of red blood cells. The kidneys play an essential role in the body, but it can be hard to tell when they’re not functioning properly and often the damage is well underway when blood tests show a problem.

One in three Australians are at risk of developing kidney disease, which occurs when the blood filters in the kidneys become damaged and excess salt and fluids become trapped inside the body. There are often no symptoms, which is why kidney disease is referred to as ‘silent’ and if untreated, can lead to kidney failure and even premature death. In fact even mild kidney failure increases your risk of a fatal heart attack. Symptoms of serious kidney failure include nausea, vomiting, fluid overload, high blood pressure and physical changes in the urine (such as blood and protein).

The commonest causes of kidney damage are high blood pressure and diabetes although kidney failure can come on suddenly, due to serious infection or a sudden loss of large quantities of blood such as in the case of a serious accident. Patients with kidney failure may need a kidney transplant or to undergo dialysis in order to recover. It’s possible to live with only one kidney, as long as it is healthy and functions well. People who donate a kidney to someone suffering with kidney disease or kidney failure can continue to lead a normal life, although of course there are risks involved.

Kidney function deteriorates as we get older, making regular GP checkups essential. The earlier kidney disease is detected, the easier it is to make lifestyle and medical changes to increase the life of your kidneys. Kidneys belonging to a healthy body don’t have to work as hard as those belonging to an unhealthy body, so you can look after your kidneys by looking after the rest of you.

What you can do to keep your kidneys healthy:

Eat a healthy diet, maintain a healthy weight and exercise (that helps both your blood pressure and diabetes prevention)

If you have diabetes, keep your blood sugar under control

Limit alcohol intake

Maintain a normal blood pressure – and if it’s high make sure you stick to the treatment

Keep your cholesterol levels in check

Maintain regular checkups with your GP

Are super foods a super myth?

You may have heard of ‘super foods’ – they’ve claimed to help prevent cancer, give you glowing skin, cure the common cold and aid in helping shed pesky extra kilos, but how much of this is fact and how much is fiction? Instead of looking for super foods as a super cure, why not look for foods that offer added benefits of increased fibre, protein and vitamins? Here are some ‘super’ choices when it comes to your diet:

Quinoa: High in protein, this seed is cooked in a similar way to rice or cous cous and can also be cooked in milk with honey and cinnamon for a different and delicious take on porridge.

Grapefruit: Like all citrus fruits, grapefruit has no fat or cholesterol, and is also packed with vitamins A and C.

Lentils: Full of protein and carbohydrate, lentils are not only good for you but they’ll keep you full for longer and have a low glycaemic index, meaning they’re good for blood sugar levels too.

Berries: Packed with antioxidants and fibre, berries will help satisfy sugar cravings due to their sweet taste. Strawberries are packed with folic acid which aids in the production of red blood cells, and cranberries can help combat urinary tract infections and aid digestion.

Ginger: This multifunctional root is said to lower cholesterol and can be used as an anti-inflammatory.

Turmeric: In India, turmeric is widely valued for its medicinal qualities. It is said to aid digestion and has antioxidant properties too – which help to fend off dangerous free radicals in the body.

Note: If you are taking prescription medications talk to your doctor or pharmacist before introducing grapefruit or cranberries into your diet, as some prescription drugs can be affected by these fruits.

Myth or Fact?

Myth

Is it safe to swallow chewing gum?

Fact

You may remember your parents telling you that if you swallow chewing gum it will sit in your stomach for seven years, and you quite possibly tell your children the same thing. It’s true that the human stomach can’t break down chewing gum like it does other foods, so the gum will remain basically intact, working its way through your digestive system before coming out during a visit to the toilet. Whether there’s any harm in that is unlikely but it’s probably best to remind children they must spit out their chewing gum when they are done with it – but not onto the pavement!

Alcohol guidelines a mystery to most

Most people are unaware of safe drinking limits, and its wreaking havoc on their health. The current Australian Alcohol Guidelines suggest both men and women should have no more than two standard drinks each day and no more than four ‘on occasion’ in order to avoid long term health risks associated with drinking alcohol, however a recent study showed less than five per cent of people can accurately identify how many standard drinks are safe to consume in one sitting to lessen the short and long term risk of health problems associated with having a few drinks.

Drinking more than the ‘on occasion’ limit of four drinks the guidelines recommend is considered binge drinking, which can lead to increased risk of accidents, violence and poor decision making as well as a variety of health problems including doubling the risk of heart disease, increasing the risk of cancer and affecting the brain and liver. Binge drinking is the second highest cause of drug-related deaths and hospitalisations in Australia.

In a recent study, more than 70% of young people believed nine standard drinks was a safe number to consume in one sitting. Men aged 25-29 and women aged 65-69 had the highest rates of risky levels of alcohol consumption. Only 6.4% of men and 8.2% of women accurately estimated the four drink cap (on occasion) as a safe number of alcoholic drinks to consume in one sitting. When it came to knowing how many drinks people can safely consume each day the respondents did a little better, estimating on average that 2.5 drinks per day was OK for men and 1.4 drinks was safe for women.

The researchers say their findings were disappointing considering the time and effort involved in developing and promoting the guidelines. The number of men and women who don’t realise the health risks involved in binge drinking is disturbingly high, particularly amongst young people. To improve short and long term alcohol related health problems people need to be aware of and adhere to the guidelines – they’re there for a reason.

PIP Breast Implants

You may have heard some stories in the media recently about risks to women with a specific brand of breast implants called ‘PIP’ implants. French regulators discovered that PIP, who manufactured and supplied the implants in question around the world, had been using a grade of silicone that was not considered medical grade. Different governments have responded to the situation in different ways, but the Australian Government has taken a world leadership role in developing a response that puts the health of patients first. They have established a committee of experts to identify potential risks, undertaken oversight testing by the Therapeutic Goods Administration (TGA) and made recommendations to the Department of Health and Ageing about funding diagnostics and also surgery should women wish to have them removed.

When the scandal broke little was known about the industrial grade silicone that has been used in PIP implants and normal arrangements for obtaining information were blocked when the PIP company closed down and declared bankruptcy. Removal of the implants involves an increased level of risk to the original implant with even more risk if the patient chose to have new implants put in to replace the old ones. So a government response that recommended removing them without weighing up the risks of leaving the implants compared to the risks of removal is unlikely to produce the best outcomes for patients.

To fill the information void the Australasian College of Cosmetic Surgeons have released a series of video clips providing factual answers to patients’ questions. You can find them at: www.accs.org.au/pip

The Causes of Cancer

There’s a lot of myth busting needed in our understanding of what causes cancer. Here’s an example of what I’m talking about. Research suggests that a powerful way to get people to stop smoking is to tell them that the tobacco leaves were dipped in pesticide. Smokers drop their cigarettes in absolute horror. There’s even a market for ‘organic’ cigarettes! We go around thinking that pesticides, preservatives and other environmental factors are major causes of cancer, when in fact, the evidence is that they’re not. What is that evidence? Well, if a chemical causes cancer, the group of people in whom it will show up most obviously are those who work with those chemicals. They have the exposure. And what’s known from that work is that while there may be – for example – a small risk from some pesticides in people heavily exposed, there’s little or none in the general community.

The common causes of cancer are known by all of us. In more than one in five people who develop cancer, the cause is smoking (lung, breast, stomach, bowel, and pancreas etc). In more than one in 20 people who develop cancer, the cause is alcohol (oesophagus, mouth, bowel and breast etc). A large percentage of cancers are made more likely by being overweight, obese and not taking enough exercise (pancreas, breast, and bowel etc). Smoke organic cigarettes all you like – but you’ll still die years sooner and in poorer health than you would if you didn’t smoke. The same goes for more than one or two standard drinks of alcohol per day, carrying extra fat and not exercising. The message is to stop fretting about hidden, tiny or non-existent causes of cancer and take up lifestyles that are known to prolong your life in good health.

Don’t ignore your body…

Our bodies tell us we are unwell through a variety of symptoms: sore throats, headaches, pain and fever to name a few. Taking a painkiller or other over the counter medication can help treat immediate symptoms, but if the symptoms persist it’s important to find the cause of the problem so it can be treated. If you have to have surgery or you are injured, your doctor may prescribe painkillers alongside other medications which will help you deal with the pain associated with your illness or injury. However, these are only intended for short term use while your body heals.

Relying on over the counter painkillers for recurrent or chronic pain won’t cure the problem. By not seeking medical advice you could be making the pain worse and increasing the risk of long term health issues. Or, you could be ignoring a serious issue that needs medical attention. Painkillers may provide short term relief, but they shouldn’t replace professional health advice that can help identify and treat the root of the problem. If you find yourself relying on painkillers, seek medical advice to make sure there’s nothing more sinister going on. Your body may be trying to tell you something, so you’re best off not to ignore it.
