Insulin is a naturally occurring hormone made by the pancreas that helps our body use or store the glucose (sugar) it gets from food. For people with diabetes, either the pancreas does not make enough insulin to meet the body's requirements, or the body cannot properly use the insulin that is made.
The yellow color in normal urine comes from a substance known as urochrome. Urochrome is also known as urobilin and is the result of hemoglobin breakdown. Hemoglobin is the protein in red blood cells that enables oxygen to be taken around the body.
Healthy urine is generally clear and light yellow in color. The yellow is caused by urochrome pigments in the urine â a normal waste product. Urine color changes may occur due to a variety of causes, some of which are not harmful. For example, eating certain foods, such as beets, can temporarily change the color of urine to red or pink. Reduced fluid intake leads to concentrated urine, yielding a deeper shade of yellow. Urine may also appear almost colorless if you drink a large amount of water.
