Any advice that we give is based on the information you have given us. You should always follow advice you have been given by a health professional.
While you don’t have a long term health problem it might be good idea to take some action.
However, if your weight has been the same for a long time, unless you have been advised to lose weight by your doctor or other health professional it might be more important for you to focus on maintaining your current weight, especially as you have said you have lost weight and regained it before.
