Losing the bulge requires lifestyle changes

Everyone knows that being overweight is unhealthy — it increases the risks of diabetes, heart disease and arthritis, amongst other things. Yet over one half of adult women and men in Australia are now overweight–a doubling in the last 20 years. And the proportion of overweight or obese children and adolescents is about one quarter (both boys and girls). Although for some the tendency to be overweight runs in the family, most people battle with the bulge simply because they don’t exercise enough and make the wrong choices when it comes to food.

Now that summer is upon us, many become dissatisfied with their body image (women in particular) and launch into exercise programs and various fad diets to change body shape. The truth is, fad diets such as the low carbohydrate diet, blood group diet, zone diet etc provide no solution in the long term.

Long-term solutions come from lifestyle changes. Yes, the weight loss will be slow and steady and most people determined to stay trim will need help from friends, family or health professionals to keep their motivation going.

Instead of focusing on a particular crash diet advertised in a women’s magazine or on the TV, do these two simple things:

  • Take an honest look at your present diet. Without changing what you normally eat, record everything you eat and drink over 1 to 2 weeks. Take this diet record to a dietician or your doctor to get advice on some appropriate changes. The advice you receive will almost always centre on reducing fat in the diet, improving the range of fresh fruit and vegetables, as well as your particular needs (eg. calcium intake in young women).
  • Start a regular exercise program. Wheel out the bike, put on the walking shoes, put on the swimming trunks or take the dog lead off the hook. Plan for 30 minutes of exercise at least 5 days a week. This exercise should be at about 60% of your maximum effort — enough to get up a mild sweat or make you slightly breathless but not enough to stop you exercising. If you have problems such as heart disease, consult with your doctor first.

    Review your progress regularly with your doctor or dietician. They will help you stay motivated.

  • Gout & Diet

    Gout commonly affects middle aged to older men, runs in families, and in most cases (75%) attacks the big toe in the middle of the night! It causes a very painful attack of arthritis with heat and swelling of the joint.

    Other areas also affected include ankles, elbows and fingers. Gout is due to the body’s inability to remove uric acid (a waste product of the body that is derived from purines). As a result, irritating uric acid crystals are deposited inside and around the joints, causing pain.
    Gout occurs more often in people who are overweight, have high fats in the blood, who drink excess alcohol, or who have kidney disease.
    Although gout can be very well controlled with medication, the diet can play a part in preventing attacks. It is calculated that about 15% of the uric acid in the blood comes from the diet.

  • The first most helpful step is to control overweight.
  • Drinking plenty of water to flush out the kidneys may also help—as much as 2-3 litres per day is recommended.
  • Reduce alcohol and coffee intake – both predispose to gout.
  • Eat less meat and fish (or extracts made from them) – these foods seem most connected with gout, possibly because of their purine content. (Other foods high in purines but for which evidence is lacking include legumes e.g., beans/lentils/split peas, spinach, sweetbreads, and yeast extracts e.g. Vegemite.)

    8 Ways to build a child’s self-esteem and confidence

    1. Treat them as an individual and enjoy them for what they are.
    2. Separate the deed from the doer—when your child does something wrong disapprove of their action but don’t reject them.
    3. Focus on their good points, not their failings—look for the good things they do and show your approval often.
    4. Reward effort—encourage them at all times when they try to do well.
    5. Have realistic expectations—if you expect too much, your child is set-up for failure, so set them goals they can achieve.
    6. Teach them the skills they need—if you want them to fill the dishwasher, groom the dog, or make their bed, show them how to do it.
    7. Reward effort, not the result—let them know you have noticed their efforts even though it may not be an ‘A class’ effort.
    8. Give responsibility and permission to fail—children thrive on responsibility because if makes them feel important but they don’t always get it right.

    Health Quiz

  • What basic healthy eating advice holds true amongst all the confusion?
    Despite all the advertising on ‘designer’ health foods the non-expensive changes for a healthy diet are: more fruit and vegetables; more cereals (preferably whole grain); less saturated fat (high fat dairy or meat); less sugar; less salt; more fish; and only drink alcohol in moderation.
  • What is the largest preventable cause of blindness?
    Glaucoma, which is abnormal high fluid pressure in the eye. 1% of people over 60 get it, increasing to 10% by aged 80. An eye pressure check every 2 years is recommended for people over 60.
  • What diseases can travellers catch from contaminated food or drink?
    Traveller’s diarrhoea, hepatitis A, cholera, typhoid, amoebiasis, giardiasis, and worm infestations.
  • What might head banging, restless nights indicate in a snuffly child?
    This could be chronic otitis media leading to deafness and earache. A hearing test and ear examination is needed.
  • In someone allergic to dairy products, what other food could be a problem?
    Soybean products, which have a protein similar to dairy - risk of reaction is 50:50.

    Whooping Cough (Pertussis)

    Even though we vaccinate our children against this bacterial infection (it’s part of the Triple Antigen), epidemic infections are still common every 3-4 years, usually in spring-summer. It is just that fewer people are affected and symptoms are much less severe. More importantly, there are less of the bacteria around the community to infect babies who are particularly at risk – 1 in 100 will die if hospitalised with the infection in the first two months of life.

    Pertussis usually begins as a typical “cold”, progressing over a few days to a persistent dry cough. When coughing, the unvaccinated child makes a “whooping” sound when they breathe in, immediately followed by vomiting. Coughing comes in bouts. Sometimes there is life-threatening obstruction to breathing or the bacteria may infect the lungs (pneumonia) or brain (encephalopathy; seizures).
    Infection is spread by coughing respiratory droplets around the place. In this way, 80% of close contacts (e.g. households; day care) become infected and 10 days later, the illness starts in them. Symptoms then last 6-10 weeks if untreated.
    Diagnosis is on the story and from tests – a swab taken from the nose or blood test.
    Treatment is with antibiotics which only work if given in the first three weeks of the illness. Infected children can return to day care after five days on treatment.
    These contacts should also be treated if in close contact with an infected person within the last 21 days:

  • Any baby under 12 months
  • Any infant between 1-2 years who has not received the 3 doses of pertussis vaccine
  • Any women in the last month of pregnancy
  • Any contact who could spread the infection to a vulnerable group e.g. child health nurse
    As well, a booster vaccine is recommended for some children contacts (ask your doctor).

  • Teenage Depression

    Remember your teen years when you were searching for the meaning of life and wondering why you didn’t seem to fit in? Things have not changed much for today’s teenagers except the pace of life is faster and teens have a greater array of life choices to grapple with, not to mention more risks. Single parent families are more common and extended families less available for support. The media keeps reminding us of all the turmoil, endlessly portraying people as winners and losers, with not much in between.

    Little surprise then that about one third of teenagers suffer emotional problems and depression and anxiety can disrupt their lives.

    Depression can cause a negative cloud to descend over everything, so everything starts to look hopeless and the adolescent feels helpless to change it.

    What can parents do about it? First, if the problem persists, acknowledge it is a problem and seek help. It is important to look behind the behaviour to any underlying issues. Pills are usually not the answer but helping the teenager work through problems can work wonders. Although family support is important, your teen may be helped more by someone independent to talk to, in confidence, so they can really open up. Ask your family doctor for help.

    Here are the tell-tale signs of depression:

  • Sad or irritable mood most days, going on for weeks.
  • Becomes withdrawn and disinterested in social activities.
  • Weight loss or poor weight gain.
  • Sleep problems.
  • Fatigue, including physical complaints that cannot be explained by tests or examination.
  • Appearing restless and agitated.
  • Poor work or school performance due to poor concentration.
  • Thoughts of death or self-harm (even suicide).
  • Inappropriate medication, alcohol or drug use.

    Bee sting Allergy

    A sting from a bee has always been a worry, even before Muhammad-Ali took on the idea! A child treads on a bee beside the swimming pool. Mum brushes up against one while gardening or Dad hits one while on his motorbike. The main thing to distinguish honeybee sting from that of the ‘yellow jacket wasp’ or paper wasp is that bees only sting once and they leave the sting behind in the skin.

    During a sting, venom is injected from a tiny sack, which stays attached to the sting left behind in the skin. This sack is why we recommend a bee sting is removed by flicking it out with a sharp object, like a knife. If you grab the sting, it squeezes the venom sack and squirts more venom under the skin.

    The venom has a number of toxins that cause pain and irritation. Depending on how sensitive you are to the toxins and how much venom is injected, the body responds by releasing its own inflammatory hormones e.g. histamine. This in turn causes redness, swelling and more pain.

    This reaction can last days and produce severe local swelling despite ice and elevation. Antihistamines often help little. It is not true bee venom allergy.

    Allergy occurs when there is a reaction away from the site of the sting. This reaction takes the form of a combination of itchy welts elsewhere on the body, wheeze, or low blood pressure (causing blackout or dizziness).

    Allergic reactions can be very quick and life-threatening. But it is not true to say that subsequent stings always cause reactions that are more severe – it is somewhat unpredictable and the reaction may be the same or less.

    Immunotherapy (desensitisation) is available for those with potentially life-threatening reactions to bee (or wasp) venom. It provides 99% protection while on treatment and strong protection thereafter.

    The treatment, which consists of injections over three years, carries its own risks. For example, an allergic bee sting reaction that is just confined to the skin (welts or swelling) is distressing but not truly life-threatening, and immunotherapy would usually not be recommended because treatment provides more risk than a further sting.

    Immunotherapy is usually recommended when:

  • Some one with asthma has a severe reaction (because asthmatics are at more risk).
  • If there is a pattern of worsening severe reactions over three or more stings.
  • Those predisposed to stings (e.g. occupation) and severe reactions, in isolated surroundings.

    Before commencing treatment, there must be a positive blood test (RAST) for bee venom. This test does not predict the strength of reaction but it confirms the presence of allergic antibodies.

  • Case Report

    Mary wants a baby. Something is getting in the way. Her problem affects up to 10% of all women.

    At the age of 30, Mary consulted with her doctor because she could not fall pregnant despite trying for two years. She had waited longer than usual because she thought her infrequent, irregular periods might mean it would take longer.

    During consultation, her doctor noted her other complaints of being overweight (and having trouble losing it!), excessive hairiness, acne and lack of energy.

    Mary was sent for some blood tests and an ultrasound scan of her pelvis.

    The tests showed that Mary was not ovulating properly. Scan revealed multiple small cysts on her ovaries.

    A diagnosis of Polycystic Ovary Syndrome was made. This is a metabolic problem that interferes with normal ovary function, along with blood fats and insulin metabolism.

    Mary was referred to a gynaecologist who could find no other problems with her or her husband.

    First step was to get Mary’s weight back to normal. She went on a special diet and regular exercise plan. As Mary’s weight decreased towards what it should be, her regular menstrual cycle kicked back in and within six months she had fallen pregnant.
