Signs and symptoms

The signs and symptoms of abnormal urine color are shown as follows:

  • Unexplained urine color other than straw-yellow has continued for a long time.[1]
  • Once observe blood in urine.[1]
  • Clear, dark-brown urine.[1]

Risk factors of clinical abnormal urine color include elderly age, strenuous exercise, and family history of related diagnosis.[2]

Cause

Infection, disease, medicines, or food can all affect urine color temporarily.[1] For instance, cloudy or milky urine usually accompanied by bad smell possibly indicates urinary tract infection,[1] excessive discharge of crystals, fat, white blood cells, red blood cells, or mucus.[1]

Dark urine that looks brown but clear might be a warning sign of a serious liver disease like hepatitis or cirrhosis. In which, an excess of bilirubin being discharged through urine.[1]

In case the urine looks in pink, red, or lighter brown is generally caused by beets, blackberries, certain food colorings, hemolytic anemia, renal impairment, urinary tract infection, medication, porphyria, intra-abdominal bleeding, vaginal bleeding, neoplasm located in either bladder or kidneys pathways.[1]

If urine looks dark yellow or similar to orange color, the causative factors might be recent uses of vitamin B-containing nutrient supplement, carotene, phenazopyridine, rifampin, warfarin and laxative.[1]

The causation or contributing factors of the urine color change to green or blue are those artificial colors seen in foods and drugs, or bilirubin medicines such as methylene blue, and urinary tract infections.[1]

Diagnosis

Doctor may prescribe some tests to help get the full picture of the situation, such as blood tests, liver function tests, ultrasound for kidneys and bladder, urinalysis,[3] urine culture for infection, and cystoscopy.[1]

Doctor may also ask for the medical history to collect information before making a diagnosis.[4]

gollark: It's likely that my code is just setting up the socket wrong somehow, since I mostly just used the multicast-looking things in the docs and rearranged the calls until it stopped saying stupid things like "OS error 22".

gollark: `ip neigh show`, right?
gollark: It says it wants a "prefix", which I assume means `ff00::/8` and stuff, but it also says nothing about that.
gollark: No idea. `ip r list ff02::aeae` doesn't say anything at all about it, but that is also the case for some *working* addresses on the LAN.
