If you're dehydrated, your tongue will probably look dry. It will also have a yellowish or whitish coating. If your tongue constantly sticks to the roof of your mouth, you're probably dehydrated. To avoid this issue, drink plenty of water.
When your body does not have enough water, it can lead to headaches, fatigue, weight gain, and of course, dry mouth. Severe dehydration can even lead to kidney failure. When someone is dehydrated, the tongue appears dry and typically has a white or white-to-yellowish coating.
A yellowish coating indicates there may be an infection in the body. A gray or blackish coating indicates a long term digestive disorder or that something may be very wrong with your body's health. A thick white coating means there may be poor circulation to the extremities or possibly a yeast infection.
A healthy tongue is pink and covered with small nodules (papillae). It is also well-moistened, with saliva functioning to help you break down food before digestion and coat and protect your teeth from bacteria and decay. If your tongue is dry and rough, it could mean that it's not well-hydrated.
In traditional medicine, purple/blue-ish tongue color indicates blood stasis [30] which is usually associated with stress and is consistent with our findings.
Rarely, yellow tongue may be a sign of jaundice, a yellowing of the eyes and skin, which sometimes indicates liver or gallbladder problems. Self-care is usually all that's needed to treat yellow tongue, unless it's related to another medical condition. Medical treatment for yellow tongue usually isn't necessary.
It can cause yellow skin (including the skin on your tongue) and a yellowing of the whites of your eyes. This buildup may indicate liver damage or dysfunction.
Signs of your body undergoing excessive stress can show up on your tongue as unusual redness, sores, and ulcers. Also, if your tongue appears to have marks around the edges, that could signify consistently biting your tongue as a reaction to stress.
A healthy tongue is pink in color. If your tongue color is white, yellow, orange, red, black, purple, gray, green or blue, it could mean you have an underlying health condition. If you have tongue discoloration that doesn't go away, tell your healthcare provider.
Liver (organ)
A yellowish or greenish liver may indicate jaundice or a similar condition, a dark brown color may indicate alcohol poisoning, a black color can indicate terminal Emphysema, and white or grayish tones may indicate cancer.
You know that your liver function is worsening if the signs of liver failure have started or are increasing. Look out for jaundice (yellowing of the eyes and skin), nausea, fatigue, and pain on the right side of the abdomen.
Liver stress sign #1 Your skin colour changes
If your skin colour changes to jaundice yellow or pale with a blue tinge, or if your nails or fingertips turn yellow, or if there is yellowing of the eyes there is trouble brewing. This change in colour happens because the body is unable to flush out the toxins.
Anxiety has also been linked to tongue swelling and scalloped tongue, which is a condition that causes waves or ripples along the sides of the tongue.
Yellow was most often associated with a normal mood and grey with an anxious or depressed mood.
Dark red to purple: A dark red to purplish tongue could indicate something as simple as a vitamin deficiency, but it could also indicate a fever or an infection, such as Scarlet fever or Kawasaki disease. Blue: A blue tongue could indicate poor oxygen circulation that may be due to lung problems.
A white tongue can look alarming, but it's usually just a sign of trapped bacteria, debris (like food and sugar) or dead cells on your tongue. White tongue sometimes happens alongside a different tongue problem called black hairy tongue.
Nutritional deficiencies include iron, folate and vitamin B12 deficiency. B12 deficiency will also make the tongue sore and beefy-red in color. Glossitis, by causing swelling of the tongue, may also cause the tongue to appear smooth. Among women, low-estrogen states may cause a “menopausal glossitis”.
