Carotenosis is a condition characterized by a yellow-orange discoloration of the skin, resulting from elevated levels of carotenoids in the body. Carotenoids are pigments found in various fruits and vegetables, such as carrots, sweet potatoes, and pumpkins. This condition is also known as carotenoderma.

Causes

Carotenosis is primarily caused by the excessive consumption of foods rich in carotenoids, particularly beta-carotene. The body converts beta-carotene into vitamin A, but when consumed in large amounts, the excess carotenoids are deposited in the skin, leading to the characteristic discoloration. Unlike jaundice, which also causes yellowing of the skin, carotenosis does not affect the sclerae (whites of the eyes).

Symptoms

The main symptom of carotenosis is a yellow-orange tint to the skin, most noticeable on the palms of the hands, soles of the feet, and nasolabial folds. The discoloration is more pronounced in areas with thicker skin. Carotenosis is a benign condition and does not cause any other symptoms or health issues.

Diagnosis

Diagnosis of carotenosis is primarily clinical, based on the appearance of the skin and dietary history. It is important to differentiate carotenosis from other causes of skin discoloration, such as jaundice, which can indicate liver disease. Blood tests may be conducted to rule out elevated bilirubin levels, which are indicative of jaundice.

Treatment

The treatment for carotenosis involves reducing the intake of carotenoid-rich foods. Once dietary intake is adjusted, the skin discoloration typically resolves over several weeks to months as the excess carotenoids are metabolized and excreted by the body.

Prevention

To prevent carotenosis, individuals should consume a balanced diet that includes a variety of fruits and vegetables, without over-relying on those high in carotenoids. Moderation is key to maintaining healthy skin coloration.
