ASK THE DOCTOR

Readers ask about knee discomfort and high cholesterol.

Q I’m 53 years old and for the past few months have had occasional ongoing knee discomfort that’s now spread to my ankle. I’m able to walk fine for a short while, but sometimes feel uncomfortable pains in the knee and ankle when walking around for a long time. Is this common? It’s also been suggested by my family that I should wear “proper shoes” - what exactly should I be looking for? M.P.

Pain in these two joints should be investigated. The most likely possibility is osteoarthritis or a musculoskeletal strain. Wearing a comfortable supportive shoe may be part of the approach to relieving the pain but you also need to work out the cause. Your GP can point you in the right direction.

Q I recently found out that I have to watch my cholesterol. What kind of adjustments should I make to my diet and lifestyle to reduce my cholesterol? S.P.

You need to reduce dietary animal fats and exercise daily. High cholesterol is just one risk factor for cardiovascular disease so have a check-up with your GP who will assess your risk and advise if you need further investigation. If you smoke, quit. If you drink excessive alcohol, cut it back. If you are overweight or obese, get yourself into the healthy weight range and eat predominantly plant-based foods such as vegetables and fruit. A dietitian could provide you with an eating plan involving intermittent fasting, which can also help lower cholesterol.
