A 10-year-old boy with polydipsia and polyuria would likely not be treated with somatropin.
This is because somatropin is often used for growth issues and even short bowel syndrome, but from what I could find, nothing about polydipsia or polyuria.
A 3-year-old cow on a dairy farm could need somatropin, specifically Bovine Somatotropin (bST) to increase milk production or fix growth issues
A 4-year-old girl with an XO genetic genotype would get somatropin because it is used to treat Turner syndrome (Same as XO genetic genotype)
A 44-year-old boy with chronic renal failure and growth deficiency would get somatropin because it is used to treat growth issues even in adults and chronic renal failure
