Carotenemia: Symptoms, Causes, and Dietary Recommendations - Gastroenterology and Hepatology

Carotenemia is a condition characterized by an excess of carotenoids in the body, which can lead to a yellowish discoloration of the skin, particularly noticeable on the palms and soles. This condition is generally benign and is primarily caused by the excessive consumption of carotenoid-rich foods, such as carrots, sweet potatoes, and various green leafy vegetables. The yellowing of the skin occurs because carotenoids are fat-soluble pigments that can accumulate in the skin, especially when consumed in large quantities.

In your case, you mentioned experiencing noticeable yellowing of the skin, particularly in the palms and soles, while your sclera (the white part of your eyes) remains unaffected, and your liver function tests are normal, except for slightly elevated bilirubin levels. This is a classic presentation of carotenemia, which is typically not associated with liver dysfunction or any serious health issues. The fact that your liver function is normal is reassuring, as it indicates that your liver is likely functioning well and is not compromised.

Regarding your dietary habits, it seems you have a well-rounded intake of fruits and vegetables, including deep green vegetables, which are also high in carotenoids. While these foods are healthy and provide numerous benefits, it may be beneficial to moderate your intake of particularly high-carotenoid foods, such as carrots and sweet potatoes, to see if this helps reduce the yellowing of your skin.
In terms of your liver function, the slight elevation in bilirubin levels could be due to various factors, including dietary habits, but it is important to interpret these results in the context of your overall health and any other symptoms you may have. Since you are scheduled for an abdominal ultrasound, this will provide further insight into your liver and gallbladder health, helping to rule out any underlying conditions that could be contributing to your symptoms.

As for your question about whether your liver function has been affected, it is unlikely that carotenemia itself would cause liver damage. However, it is always wise to maintain a balanced diet and avoid excessive consumption of any one type of food. If you have concerns about your liver health or the implications of your dietary choices, it would be prudent to discuss these with your healthcare provider, who can provide personalized recommendations based on your health status and dietary habits.

In summary, carotenemia is generally harmless and can often be managed by adjusting your diet. Reducing the intake of high-carotenoid foods while maintaining a balanced diet rich in a variety of nutrients is advisable. Monitoring your liver function through regular check-ups and imaging studies, like the ultrasound you have scheduled, will help ensure that your liver remains healthy. If you notice any new symptoms or changes in your health, be sure to communicate these to your healthcare provider for further evaluation and guidance.
