If your tongue is yellow, be careful with these 5 diseases
A yellow tongue is caused by a number of factors, including poor oral hygiene, smoking and chewing tobacco, dry mouth, jaundice, and certain medications.
Here are five dangerous conditions that can cause your tongue to turn yellow:

1. Symptoms of Jaundice
When you notice a yellow tongue, be sure to look out for other symptoms of Jaundice. This health condition is marked by certain changes in skin color and a distinctive change in eye color.
This yellow tongue condition is mainly caused by the accumulation of bilirubin in the blood. Bilirubin is a yellow waste product produced when red blood cells are broken down. Jaundice can be caused by a number of factors, including liver disease, gallbladder disease, and some blood disorders.
2. Anemia
Anemia is a condition in which the blood lacks the number of red blood cells needed for the body to function properly. Red blood cells carry oxygen to tissues throughout the body, which is affected when there is a shortage of red blood cells.
Anemia can cause a number of symptoms including – fatigue, shortness of breath and pale skin. It can also cause a yellow tongue.
3. Symptoms of liver failure
Another condition that can cause a yellow tongue is liver failure. This is a serious condition in which the liver cannot function properly. When your liver is not functioning properly, it can cause a build-up of bilirubin in the blood.
Bilirubin is a yellow waste product that is produced when red blood cells are broken down. When this does not happen because the liver is not working properly, bilirubin can build up in the blood causing your tongue to turn yellow.
4. Symptoms of kidney failure
Kidney failure is a serious condition in which the kidneys cannot filter waste products from the blood. This can lead to a variety of symptoms, including a yellow tongue.
Kidney health is affected by a number of lifestyle factors, which can lead to an excessive build-up of bilirubin in the blood, resulting in jaundice. The kidneys are responsible for excreting bilirubin through urine. When the kidneys fail, they cannot excrete bilirubin effectively, leading to a build-up of bilirubin in the blood and causing jaundice.
5. Poor oral hygiene can cause your tongue to change color
Poor oral hygiene is the most common cause of a yellow tongue. This mainly happens when you do not keep your mouth clean, allowing bacteria and food particles to build up inside your mouth and tongue, causing the tongue to change color. Bacteria can also produce pigments that contribute to the yellowing of the tongue.
A yellow tongue is not a condition that should be taken lightly. It is a warning sign that your body is signaling you when a dangerous disease is slowly disrupting your system and causing havoc inside your body. It is important to find out the cause of the sudden change in tongue color. In some cases, such as when the yellow tongue is caused by poor oral hygiene or smoking, the yellow tongue may resolve on its own with lifestyle changes.
