Example 1: A 65-year-old male with benign prostatic hyperplasia experiences increased urinary frequency at night, impacting his sleep quality. He is diagnosed with nocturnal polyuria and treated with medication to shrink the prostate., A 30-year-old female with uncontrolled diabetes mellitus presents with excessive thirst and frequent urination, including during the night. She is diagnosed with nocturnal polyuria secondary to diabetes and her diabetes management plan is adjusted., A 40-year-old male with no significant medical history complains of frequent nighttime urination. After ruling out other causes, he is diagnosed with primary nocturnal polyuria and prescribed medication to reduce urine production at night.
Documentation should include the frequency and volume of nighttime urination, any associated symptoms like thirst or pain, relevant medical history, physical exam findings, results of diagnostic tests, and the treatment plan.
