What should you know about dark colour urine causes?

Dehydration commonly concentrates urine after sweating, fever, vomiting, diarrhea or low intake. Heat Exhaustion can combine fluid loss with headache, weakness, nausea and heavy sweating. Liver inflammation, including Hepatitis A or Hepatitis B, may cause brown urine with yellowing, itching, nausea or poor appetite. Infection may bring burning, urgency, cloudy urine or fever, while a stone can cause severe side or groin pain. The same shade can have different causes, so symptoms and timing matter.

Note when the change began, how often it occurs and whether it follows exercise, heat, a new product or an illness. Drink normally unless you have been given a fluid limit. Keep a list of medicines, vitamins and supplements. Record pain location, fever, urine frequency, odor, blood, stool changes and yellowing of the skin or eyes. This information helps a clinician choose whether urine testing, blood testing or another examination is appropriate.

Seek medical advice if the color persists, repeatedly returns or occurs with urinary symptoms. Seek urgent care for severe side or abdominal pain, inability to pass urine, repeated vomiting, fainting, confusion, very little urine or yellow eyes and skin. Do not assume dark urine is simple dehydration when there is blood, fever or significant pain.
