Hello thanks for choosing HCM for your health related queries Cooking raw rice on compulsive basis and inability to stop is probably due to Pica. Pica is eating of non-nutritive substances commonly clay, sand etc but even raw rice comes in that category. Pica can occur in an individual due to a number of medical conditions like- - One possible reason behind this behaviour is probably iron deficiency anaemia. In anaemia individuals start eating inedible materials. Some times these symptoms got aggravated during pregnancy. - Pica can occur due to severe underlying anxiety. To some extent the disorder is related to obsessive compulsive disorder. Eating raw rice will not harm much if we consider physical health but it may affect individuals mental heath and may land up in embarrassing situation. So I would advise you to consult a psychiatrist for treatment. Anti anxiety drugs especially Fluoxetine, Paroxetine etc have excellent efficacy in controlling undesired behaviour. Iron supplements also help to reduce symptoms. Visit a psychiatrist for prescription. Thanks, hope this helps you. Take Care
