Why are the whites of my eyes not white anymore? I’ll tell you a secret: redness of the whites of the eyes is the most dangerous

The color of the whites of the eyes directly reflects a person's physical condition. The whiter and clearer the whites of the eyes are, the healthier the eyes are. If the whites of the eyes are blue, it means that the body is lacking iron. At this time, you should pay attention to supplementing foods rich in iron. But some people have red whites of the eyes, which is very confusing. Is there something wrong with the body? At this time, you need to check whether the eyes are infected by a virus, causing inflammation. So what exactly causes the redness of the whites of the eyes?

Blue whites of eyes – anemia

Some people's whites of the eyes are not porcelain white, for example, the whites of the eyes are blue, which is medically called blue sclera. If the whites of your eyes are blue, it means that your body lacks iron. This is because the human sclera is composed of collagen tissue, and the synthesis factors of collagen tissue include iron. If there is a lack of iron, not enough collagen tissue can be synthesized and the sclera will naturally become thinner and unable to cover the choroid. The choroid is brown-black in color and under natural light, the sclera turns light blue. Most people with blue whites of their eyes suffer from chronic iron deficiency anemia. Such people can take iron supplements or improve their nutrition through diet therapy. If the whites of a child's eyes are blue, it can basically be considered as anemia.

Redness of the sclera

The most common type of scleral redness is congestion caused by inflammation due to bacterial or viral infection. If this is accompanied by increased secretions or severe foreign body sensation, go to the hospital for diagnosis and treatment immediately. In addition, patients with hypertension may experience redness of the sclera before suffering a cerebral hemorrhage, and patients with severe insomnia may experience redness of the sclera when they suffer from heart failure. In addition, people who suffer from poor sleep for a long time will have red bloodshot eyes. Finally, if red spots appear on the sclera, it is often the result of dilation of the capillary terminals, which is more common in diabetic patients. It should be said that scleral redness is the most common and has the greatest significance in indicating disease.

Yellowing of the sclera

If the whites of a newborn's eyes turn yellow, it is jaundice. If it is an adult, there are mainly two situations: one is abnormal liver function, increased bilirubin in the blood, and yellowing of the whites of the eyes. This type of yellowing is a uniform yellowing of the whites of the eyes; the second type is caused by high blood lipids. This yellowing is localized and a bit blackish. If the whites of adults’ eyes turn yellow, they need to adjust their lifestyle habits. Don't drink alcohol, don't eat spicy food, and try to eat a light diet.

Green spots on the whites of the eyes – intestinal obstruction

If you find small green spots on the whites of your eyes, it is most likely an early sign of intestinal obstruction. Other early signs of intestinal obstruction are not obvious, so be cautious when small green dots appear.

Scleral spots

If triangular, circular or half-moon shaped spots of various abnormal colors appear, it is usually a sign of intestinal parasitic disease.

If blood stains appear on the whites of the elderly’s eyes, they should pay attention to monitoring their blood pressure and blood lipids, and strictly control their diet and eat less high-cholesterol and greasy foods.
