* Carotenemia: This is a condition that occurs when you have too much carotene in your blood. Carotene is a pigment found in many fruits and vegetables, such as carrots, sweet potatoes, and spinach. When you eat too much carotene, it can build up in your skin and give it a yellow tint.
* Liver disease: Liver disease can cause a yellowing of the skin, including the palms of the hands. This is because the liver is responsible for breaking down carotene and other pigments. If the liver is not functioning properly, these pigments can build up in the skin and cause it to turn yellow.
* Thyroid problems: Thyroid problems can also cause a yellowing of the skin. This is because the thyroid gland helps regulate metabolism, and when it is not functioning properly, it can lead to a build-up of carotene in the skin.
* Medications: Some medications can cause a yellowing of the skin, including the palms of the hands. These medications include chloroquine, hydroxychloroquine, and minocycline.
* Rare conditions: There are a few rare conditions that can also cause yellow palms, such as Wilson's disease, hemochromatosis, and Gilbert's syndrome.
Here are some additional things to keep in mind:
* The yellowness of the palms is usually bilateral, meaning it affects both palms.
* The yellowing is usually not accompanied by any other symptoms, such as itching, pain, or swelling.
* The yellowing may be more noticeable in the winter when the skin is less exposed to sunlight.
