Revealed: Why Nandi sisters eat soap

Initial tests done on two young women, whose appetite for soap has refused to die, have revealed that they are anaemic and are suffering from severe iron deficiency. The two sisters, Sharon Chepchirchir, 24 and Lydia Chepkemboi, 17, were tested by doctors at Oak Tree Hospital in Eldoret on Thursday. Dr Mathew Koech, who led a team of medical specialists in conducting specialised tests on their blood said the deficiency could point to the reason for their weird cravings although he said they will be doing further tests.
