Older adult who has known allergies to wool, perfumes and some types of nuts (not peanuts tho). Long, long history of non-specific stomach problems. Basically this person is always in the loo. Often needs to go urgently, frequently, diarhoea (sorry for spelling and TMI). Worse when she eats obviously irritating foods like curry but bad even at the best of times. She does eat a lot of bread, dairy, cheese etc. Do you think there is any benefit in investigating things like dairy or wheat intolerance?
