i have had diarrhoea now for 3.5 weeks, whether it be watery or just loose. i have had tests done for food poisoning but came back clear. i have absolutely no abdominal pains with this, no blood in stools, no loss of appetite (in fact my appetite has gone through the roof). i am also not suffering from any lack of energy or tiredness even though i still go to gym 4 times a week and play football once a week. my doctor just now seems to be going through tryin me on different medication every week in the hope that something works!! any ideas?
