What could be wrong?

### output:

Thanks for posting your query here. Newborn jaundice which usually appears around day 3-5 of life is usually physiological. This is related to immaturity of liver and as the liver becomes more mature, the jaundice disappears. This type of jaundice is very common. Not all the babies having physiological jaundice need treatment. I would like to know what his blood results were when he was first treated for jaundice? Is there any mismatch between yours and your sons blood group? Treatment helps to lower the jaundice levels, but it doesn't disappear completely. That's the reason that eyes did not clear.You've mentioned that his jaundice has increased and head is bigger. I would like to know his recent blood results - Bilirubin and his CBC. Have you been breast-feeding him exclusively? Is he gaining weight? Also, for increased head size, please get is measured and discuss with your current doctor whether that is normal for his age or not. There are a lot of things to consider - clinical examination, blood test results etc. before diagnosing what's exactly wrong. Please do return with the results of blood test and further answers to questions I want to know, and I will be able to guide you further. Regards Chat Doctor.
