readers’ health questions answered

QI suffer from terrible anxiety, which keeps me up at night. Do you have any advice or techniques to stop worrying? K.F.

Lifestyle measures first: exercise daily, yoga; time and task management; cutting stimulants like caffeine and nicotine; avoiding alcohol; and a wind-down evening routine. Your GP can refer you to a psychologist for relaxation strategies and anxiety counselling. Medication can help in the short term.

QMy teenage daughter has become self-conscious about red stretch marks on her thighs and hips. We are trying different oils and skincare products, but nothing seems to work. Will they go away? L.P.

Stretch marks are more obvious in the early stages, but tend to fade with time. She can help by drinking 1.5 litres of water a day and exercising daily to avoid excess weight gain. Your GP may recommend a retinoid cream. Down the track, she may look into laser or microdermabrasion treatment.

QMy eight-year-old niece is overweight – her parents feed her large portions and a lot of sugary foods. I’m concerned about the health implications. What can I do? S.K.

You are right to be concerned. Poor diet and childhood obesity put her at risk for future health problems. How you handle it depends on the relationship you have with her parents, who are ultimately responsible for her nutrition. You could start by expressing concern.

QI have recently been told I have HPV following the detection of abnormalities after a routine Pap smear. I don’t smoke and I eat healthily, but am concerned these cell changes may progress. What can I do to help my body clear the virus? W.E.

Most cases of HPV infection do resolve spontaneously. Lots of vegetables and fruit in your diet are essential, with a special mention of cabbage, broccoli, kale and Brussels sprouts. A supplement with antioxidants (vitamins C and E) and folic acid may be helpful. Exercise, sleep and stress management are important. You will need to continue with regular Pap smears.

QI get hay fever every spring. My doctor suggests antiallergy nasal sprays and antihistamines, but they don’t make a difference. What else can I try? R.D.

Avoiding hayfever is frustrating because the allergens are often environmental, airborne and difficult to dodge. Some people find they have to stay indoors with the windows closed on windy days. The nose sprays and antihistamines do usually relieve symptoms. Don’t use a nasal decongestant spray because they lead to rebound congestion. Lactobacillus LGG probiotic and vitamin C may help.
