Q One of my breasts is bigger than the other. Is this normal?

Samantha, 21.

A Most people are not perfectly symmetrical, although it may be more noticeable in some individuals. If this has always been the case then it is it is unlikely that you have anything to worry about.

However, if you have noticed a new change; such as one breast getting larger, any skin redness or nipple changes, or indeed pain in one or both of your breasts, then you need to see your GP urgently for assessment and to be examined.

Q I’m struggling to lose weight and I’ve been told that I’m now obese. I don’t want any major surgery. Can you still have a gastric band?

Kerry, 43.

A Gastric bands have largely been phased out and weight loss surgery now involves procedures that reduce the volume of your stomach, limiting the amount you can eat at any one point, as well as bypassing a part of your small intestine, so that you do not absorb as much from your food.

As you highlight, these are major procedures which require careful consideration.

However, if you have struggled to lose weight for a long time, you need to be honest about when it is time to seek help.

A discussion with your GP would be the start. He or she can refer you to the local Specialist Weight Management Service, which will support you all the way through your treatment.
