ASK THE DOCTOR
QI have a few family members with high cholesterol and I’ve heard that a vegan diet can reduce cholesterol so well that medication may not be needed. Is this true, and would you suggest trying it? M.B., NSW.
Elevated cholesterol is one risk factor for cardiovascular disease. Research has shown that you can certainly lower your cholesterol level with a vegan or plant-based diet. You need to be careful to avoid nutritional deficiencies, especially iron, zinc, magnesium, protein and vitamin B12, with careful meal planning or supplementation.
QMy gastroenterologist told me that I should continue taking a fibre supplement with laxative to manage my “slow transit” indefinitely.
Are laxatives really safe for long-term use? J.N., NSW.
Slow transit constipation can be very uncomfortable and difficult to treat. A fibre supplement and laxatives provide some short-term relief, but long-term dietary changes (whole grains, leafy and raw vegetables and fresh fruits) can make a big difference and may minimise the need for long-term laxatives.
Psyllium husk is a natural fibre supplement. A comprehensive stool analysis may show a dysbiosis, which may be relieved by specific probiotics.
QI saw in the news that you spotted a serious infection on a reporter during an interview. Apparently she had contracted it during a manicure. How can I be sure I don’t get a similar infection at a nail salon? A.O., Tas.
Check the hygiene protocols in the salon: does the technician wear gloves? Are the instruments sterilised in an autoclave (a small benchtop machine using steam)? Avoid cuticle pushing and clipping. Emery boards are reused, so take your own with you. If your skin is nicked or grazed, quickly apply an antibacterial ointment and a clean dressing. See your doctor if skin becomes inflamed or infected.
Q My teenage daughter seems to have rosacea. Her skin is still so young and delicate, I don’t want to put her on strong acne skincare. What should I try? S.Z., Qld. Rosacea is more common in people over 40, so it is most likely your daughter has acne rather than rosacea. Her GP or a dermatologist can confirm that. Treatment depends on its severity, and ranges from topical to oral forms. Q I read that obesity surgery is on the rise in teenagers and my grandson is really struggling with his weight. Is it a good idea? M.H, SA. At least one in four schoolaged children in Australia are overweight or obese. Surgery for children is a last resort, when all other conservative measures have failed. These include increasing physical activity, limiting screen time and controlling food intake. See his GP and a dietician.
