Dehydration: Frequent urination can cause dehydration, if fluid is not administered to replace that lost in the urine. If a person has normal kidneys, they try to conserve water in a dehydrated state. The result, in this case, is a small amount of concentrated urine is eliminated by the dehydrated person.

No: When dehydrated you will make less urine. If dehydration is severe enough you will not urinate at all.
