What causes urine to be the color of iced black tea?
Tea-colored urine may result from physiological factors, or it could be caused by pathological conditions such as urinary tract infections or urinary system stones.
I. Physiological Factors
In women, during menstruation, a small amount of menstrual blood may mix with the urine, causing it to appear tea-colored. This is a normal physiological phenomenon, and urine color typically returns to normal after the menstrual cycle ends. Generally, no treatment is required.
II. Pathological Factors
1. Urinary Tract Infection
Infections such as cystitis or urethritis can cause inflammation, leading to local mucosal damage and bleeding. Blood entering the urine results in tea-colored urine, often accompanied by symptoms like painful urination, frequent urination, and urgency. Treatment may include medications such as levofloxacin tablets, ciprofloxacin tablets, or ofloxacin tablets, taken under medical supervision.
2. Urinary System Stones
Stones in the bladder or urethra can injure local tissues, causing red-tinged urine along with symptoms such as difficulty urinating and pain during urination. Treatments may include herbal formulations like Shenshitong Granules, Pashi Granules, or Pashi Decoction, taken as directed by a physician.
In addition, tea-colored urine could also be caused by hyperbilirubinemia.
