I feel like bile is not getting reabsorbed. I 5 months I have gained 8 kg weight. I didn't do any physical activity due to exams. My stool is brown colour and normal with diarrhoea very rare. But I see green fluid around brown stool in toilet after passing motion. I have taken liver function test, CBC and all levels are normal in range. I am feeling very worried. Can u please tell me what's is this about.
