Hello , Scoliosis can increase if you dont maintain your posture right or dont start strenghtening the weak muscles. Plus with the growth in height there are chances of its degree increasing how much degree in each year its difficult to say it depends on the cause of your scoliosis how are you maintaining it and as per your body structre . There is also a possibility it may not grow. Would suggest to visit an orthopaedic for consultation and visit a physiotherapist for your posture and back exercises!
