What can cause jaundice?

I looked at my eyes today in the mirror and it looks kind of yellowish. I'm not sure what is wrong with it, but I think I'm jaundice and I'm not sure what can cause it. I hope someone can help me here. Thanks!

Jaundice occurs when excess bilirubin builds up in the liver, causing the skin and whites of the eyes to develop a yellowish tint. Bilirubin is produced when hemoglobin from red blood cells is broken down by the body.

The only thing that causes jaundice is if the liver isn't functioning properly. Of course, there are multiple causes of liver failure (you can google that) but if the whites of your eyes are yellow, I'd for sure make a Dr. appointment. How are you feeling? Usually tiredness coincides with liver failure.

Babies are born with a generous supply of red blood cells, which help transport oxygen. Over time, these red blood cells break down, forming bilirubin in the process.

Bilirubin is normally transported to the liver, where it's processed before being eliminated from the body. But newborns initially have more bilirubin than their livers can handle, and the excess causes their skin and, sometimes, the whites of their eyes to turn yellow. This type of jaundice, called physiologic jaundice, typically appears on the second or third day of life.

Although any newborn can develop physiologic jaundice, it occurs more often, and is sometimes more severe, in premature babies because their livers are even less developed than are those of full-term infants.

Sometimes a baby may develop jaundice for other reasons. If jaundice is present at birth or appears within 24 hours, it may be the result of:

Severe bruising
An infection in your baby's blood (sepsis)
An incompatibility between your blood and your baby's
Jaundice that develops in or lasts past the second week of life may be due to:

A liver malfunction
A severe infection
An enzyme deficiency
An abnormality of your baby's red blood cells

adults:
Jaundice, also known as icterus (attributive adjective: "icteric"), is yellowish discoloration of the skin, conjunctiva (a clear covering over the sclera, or whites of the eyes) and mucous membranes caused by hyperbilirubinemia (increased levels of bilirubin in the blood). This hyperbilirubinemia subsequently causes increased levels of bilirubin in the extracellular fluids. Typically, the concentration of bilirubin in the plasma must exceed 1.5 mg/dL[1], three times the usual value of approximately 0.5mg/dL[2], for the coloration to be easily visible. Jaundice comes from the French word jaune, meaning yellow

Acute liver Failure. Jaundice is the first sign. causes are paracetamol overdose, large quantities of alcohol consumption. Viral Hepatitis, Hep A or B, acute fatty liver of pregnancy,

It could also be side effects of any medication you are taking.
Or it could be Bacterial Conjunctivitis a simple eye infection.

See you GP immediately.

Conditions of the liver such as hepatitus, cirrosis, etc. Sometimes new borns have it for a short period of time after birth. Go get it checked out.
