How can i increase my height? pls suggest some doctor guys ?

My brother had a pituitary gland issue and he was stopping growing around 5ft 6in and then we went to a nutritionist and he is now 6ft 2in at 18 years old.

Swimming is one of the best ways to increase your height .Cycling also would help you increase the height . Swimming is one of the best exercise for a body as it expands and strengthens your muscles , in my school days i myself did swimming for about an year and it helped a lot within 4 months (but i didnt stop and continued swimming for abt an year ,really made me healthy,tall n fit ) my height increased to about 8 inches can u believe that but its a fact true to me ,infact i used to cycle 3 kms to reach swimming pool and swim and then again 3 kms bk home ,so both cycling and swimming did the wonderful job. You dont have to worry if you dont know swimming ,join a club they will teach u not that difficult and intially u can get a tube to float on ,but i would suggest that only for 1 or 2 days so that u get into learning actual swimming and not just float on water like kids , u arent a kid atleast for swimming now,u going to be 18 soon. Just the process of learning swimming and doing in regular as much as you can will help u increase the height for sure and if u take care of ur diet ur health also will be gud.My height is 5.11 ft . Gud luck to u ! Happy cycling , happy swimming .

i don't think thats really possible?
