Other than that, it can be due to excessive intake of liquids, diuretic substances (including tea, caffeine, alcohol
, certain drugs), anxiety, exposure to cold, diabetes
mellitus, diabetes insipidus (central or nephrogenic), urinary tract infections or obstruction, etc to name a few more common ones. I suggest you to take opinion of your doctor who would do a clinical examination and advice for needful tests.
I hope it helps.
