Hello, Welcome to Health Care Magic Repeating thoughts about stomach problem resulting in loss of work or social performance could occur due to hypochondriac ideas. Other possibility is irritable bowel syndrome. Both are psychiatric disorders which are characterised by preoccupation with abdominal complaints. In hypochondriasis individuals have anxiety about getting some serious illness. While in IBS they have multiple complaints related to stomach like alternating constipation or diarrhoea. Consult your psychiatrist for proper treatment. Medicines like levosulpiride, amisulpiride etc have good results in such symptoms. Only in some individuals medicines like SSRIs are needed. Clinidium bromide and chlordiazepoxide combination have good results in anxiety due abdominal complaints. Consult a psychiatrist for help and improve dietary habits. Thanks
