ASK THE DOCTOR
QI experience vagally mediated atrial fibrillation. When the vagus nerve kicks out it affects the heart, throat, voice, stomach and bladder. How can I stop this nerve from “misfiring”? C.P., NSW.
Vagal atrial fibrillation is an often unrecognised condition which may affect younger patients with structurally normal hearts. Episodes of irregular heartbeat occur mostly during or after a meal, at rest or during sleep. Exercise can help control episodes. Your cardiologist will advise on the appropriate amount and type of exercise, and whether medication is indicated for your case.
QI have bipolar II and severe depression. My doctor has switched me from a long-term antidepressant to a mood stabiliser. I’m about to increase the dosage, but have read that the side effects are depression, anxiety and thoughts of suicide – all the things I suffer from. What should I do? M.B., WA.
It’s always important to read the consumer medicines information before you start a medication. While mood-modifying medications are aimed at relieving anxiety and/or depression, there can be paradoxical effects, where anxiety or depression get worse. It is important to be alert to this and report it to your doctor.
QThis is not really a health problem, but it could become one. My specialist says I’m not to use a waterproof mascara. Could you advise me on some affordable brands that are safe to use? E.S., NSW.
In general practice we are asked for all sorts of practical advice, so your question is not unusual. Non-waterproof mascara is easier to remove, so people with allergies, or sensitive eyes or eyelids, may find it better for daily use. Find the best brand for you by visiting a retailer with multiple options. Remember to remove make-up before bed.
QWhat causes muscle spasms? They come on while in bed at night. I take magnesium tablets and also use a magnesium roll-on gel, which gives relief. M.M., NSW.
Muscle spasms can have many causes, including magnesium deficiency, overuse, fatigue, and dehydration. Magnesium supplementation may help relieve spasms. Remember to stretch after exercise. Yoga can help with this. A warm bath before bed may help your muscles relax, too.
QMy son has just been diagnosed with sleep disordered breathing, and will have a sleep study soon. We’re told all children should be treated, but not necessarily with an operation. What are the other options? N.A., Qld.
If the sleep study confirms sleep apnoea, a common cause in children is enlarged tonsils and/or adenoids, and you may be advised to have them surgically removed. Other causes include obesity and allergic rhinitis (hayfever).
