Dr Zak Uddin answers your health and well-being questions...

Q I have been told that I’ve got moderate arthritis in my knees. I’m very keen not to have an operation. I would like to know if I’m damaging myself by continuing to exercise.

Ralph, 67

A Your approach is very sensible, and indeed most evidence would suggest that your own joints are far superior to any replacement and should be maintained unless having a replacement is the only option. By exercising, you are unlikely to be doing damage to the knees, but will be strengthening the ligaments and muscles around them, which might actually improve your pain. Exercise will also be improving your heart as well as helping to keep your weight down. It may also keep your mood up. However, if a particular exercise brings on pains in the knees, I would advise swapping this for another one that does not.

Q I am about to have my first child and am torn between breast feeding and bottle feeding. I’ve read that breast feeding is best, but I’m worried about being tied to my baby and my partner feeling left out.

Stephenie, 21

A Congratulations on your imminent arrival! Although there are advocates of both methods of feeding, it would probably be unfair to advise one over the other, as it is a very personal choice. What matters is that it is a decision that you are comfortable with and works for your personal circumstances. If you are afraid of breast feeding, please do not worry; there will be numerous people able to help you. There would be no harm in trying this method first to see if it suited, knowing that there is the option of bottle feeding if you find breast feeding does not agree with you. Please do not worry about your partner; I am sure they will find many other ways to bond effectively with your new arrival. Good luck!
