If there is oil substance in it then it may also be an indicstor of certain kidneys issue ssuch as glomeruolnephritis. An overactive bladder is another common cause of frequent urination. Overactive bladder is usually a collection of symptoms that can lead to frequent urination. These include: urinary urgency, or the sudden urge to urinate, caused by muscle contraction, urge incontinence, or loss of bladder control. Excessive caffeine, nicotine, and alcohol may also irritate the bladder walls and can worsen frequent urination symptoms. Treatment for frequent urination depends on the cause.

If an infection is at fault, your doctor will prescribe antibiotics for getting rid of the infection. Hope this answers your question.
