But, if your newborn has a low birth weight or had a premature delivery, your baby might show distinctive features of jaundice. Mostly, healthy babies present with mild to no symptoms of jaundice. Stercobilinogen is excreted out through stools. Urobilinogen is absorbed back again to be released into the blood circulation, some of which re-enters our liver while the rest of it is removed by our kidneys in the urine. The intestine also splits it down into urobilinogen and stercobilinogen. This processed bilirubin flows through the bile duct and enters the intestine.
Our liver takes up this bilirubin for its further metabolism. Globin and iron are re-utilised in our bone marrow to produce new haemoglobin, whereas biliverdin is broken down again to leave a byproduct called bilirubin. During this process, the haemoglobin which is inside the old RBCs is broken down into globin, iron, and biliverdin.
Our body keeps generating new red blood cells (RBCs) and wards off the old ones. If left untreated, it can affect the brain of the child, and other complications like sepsis, liver and kidney diseases or failure. In babies, phototherapy and blood transfusion, while in adults, it includes removal of the causative factor, medications and sometimes, a surgery. In adults, other symptoms are also seen such as stomach pain, loss of appetite, weight loss, etc. Newborn babies usually have jaundice, but adults can suffer from it too. The symptoms include yellowing of your skin, the white part of your eyes, and mucous membranes (linings of internal soft organs such as mouth). Jaundice is a disease in which the total serum bilirubin (TSB) level rises above 3 mg/dL.
