How to stop height..?it growing to much

Gigantisme: If you are growing too much- more than expected, meaning that your parents are not tall, but you are very tall and continue to grow- your condition may be abnormal and you should go to see your doctor for more evaluation. You would need to get some blood work and some imaging like MRI of the head is likely to be done. Referral to an endocrinologist & neurosurgeon can be done accordingly as needed.
