ASK THE DOCTOR
QMy 24-year-old daughter has developed a small, pea-sized lump behind her ear. There’s no change to the skin and it doesn’t seem to bother her apart from wondering if it’s okay or not. What could it be and should she see our GP? K.B., NSW.
It is most likely an enlargement of a postauricular lymph node. This can be in response, for example, to an infection. If it persists longer than a few weeks, or becomes larger or painful, or if she develops other symptoms such as fever, lethargy or earache, she should see her doctor for investigation.
QMy five-year-old son has had blood tests that point to slightly low iron as well as thalassemia minor, which his dad also has. What do I need to know to help him manage this? T.R., WA. Mild iron deficiency can be a feature of thalassemia minor, an inherited blood disorder affecting the production of haemoglobin which can lead to anaemia. This is common in people with Mediterranean, Middle Eastern or Asian background. The mild or minor form of the disease does not need active treatment. You have to be careful with iron supplementation as it may cause iron overload, but folic acid supplementation may be recommended.
His specialist will advise you.
QI’d like to turn over a new leaf in January and take better care of myself. Where should I start with supplements? Does it matter if they’re a pill or powder? Is a multi-vitamin okay or should I have some specific testing done first? S.H., NSW.
Great to hear you are focussing on your wellbeing for the New Year! I would suggest you start with a medical check-up and check your nutritional status. Next step is an exercise plan and a new eating plan. Any supplements would be prescribed based on your diet, medical condition and test results.
QWhat are the signs of kidney problems and how do I look after my kidneys? A.K., Tas. You can lose 90 per cent of kidney function before you notice symptoms. Have regular check-ups, including kidney function tests. Maintain a healthy weight, eat healthily and stay active. Don’t smoke. Keep salt to a minimum. If you have diabetes, make sure it’s well managed. Visit kidney. org.au for more information.
