5 eye symptoms that may reveal underlying health issues

The eyes are called “windows to the body”, and research suggests they can often signal underlying health issues. Subtle changes in eye appearance aren’t just cosmetic and may be the body's way of addressing nutrient deficiencies or serious diseases. Recognizing early changes and possible links to health problems can potentially prevent complications. Below we mention six eye symptoms and their possible links to health issues.
These eye symptoms do not guarantee a specific diagnosis. Many symptoms may also be influenced by genetic or environmental factors. any change should only be evaluated by a healthcare professional for proper treatment.

Scleral icterus or yellowing of the white part of the eyes can be a signal of liver dysfunction. As per WebMD, yellowing can be caused by accumulation of bilirubin, which is a pigment produced when red blood cells are broken down.
The liver normally processes bilirubin, which is later excreted through bile. When production exceeds the liver's ability to clear it, or bile flow is blocked, bilirubin rises and deposits in tissues.

Xanthelasma or soft, yellow plaques around the eyelids can signal high LDL cholesterol levels or other lipid abnormalities. As per NIH, these are soft, semisolid, yellow plaques that contain cholesterol.
A study published in Researchgate found that about 50% of individuals with xanthelasma had abnormal lipid profiles, suggesting it can be an external marker of dyslipidemia and an independent risk indicator for atherosclerotic cardiovascular disease.

Conjunctival pallor can indicate low haemoglobin and anaemia. Normally, the inner lining behind the lower eyelids is pink. However, in individuals with low haemoglobin or anemia the conjunctiva appears pale due to reduced red blood cell mass and oxygen-carrying capacity.
​Studies conclude pale appearance of the conjunctiva and tongue are among the most reliable physical signs of anaemia.

​Exophthalmos or bulging eyes can be a sign of hyperthyroidism, particularly Graves' disease. Graves’ disease is an autoimmune condition that stimulates the thyroid gland to produce excess thyroid hormone. As per American Thyroid Association, exophthalmos usually appears within the first year of diagnosis of Graves’ disease, and the bulging occurs due to inflammation and swelling of the eye muscles and fat behind the eyeball.

Puffy eyes may not always signal lack of sleep. NIH research suggests periorbital edema or puffy eyes can result from fluid retention. In this condition excess water accumulates in the delicate tissues around the eyes. In mild cases, fluid retention can be harmless, but persistent or severe fluid retention can be harmful, depending on the underlying cause. Untreated fluid retention may spread in legs, lungs or around organs, and in severe cases may even lead to kidney or heart issues.

Eye symptoms serve as a warning sign, but only a medical evaluation can determine the root cause. While some symptoms can be managed with lifestyle intervention and dietary changes, others may require medical treatment. If an individual experiences any of these symptoms, consulting with a healthcare professional and early diagnosis can help prevent future complications.
