Hi, thanks for using healthcare magic A kidney infection would present at least with urinary symptoms such as frequent urination, the urge to go the bathroom often, discomfort on urination, possible malodour of urine or blood in the urine. Fever and abdominal pain can also occur but there is always a history of urinary symptoms. If there are no such symptoms then it is unlikely that she is experiencing a urinary tract infection. She may be experiencing gastroenteritis if she states that the symptoms are cramping abdominal pain and the feeling as though diarrhoea is about the start. The most important aspect of gastroenteritis is fluid management. She would need to replace any losses with fluid. It would be best to use an oral rehydration fluid. She may want to avoid solid food for now and concentrate on fluid. Yogurt with probiotics would also be helpful. I hope this helps
