The DI Toilet Facilities Card is for use in public places, such as shops, if public conveniences are not easily accessible.

If you would like a card, please send a stamped self-addressed envelope to the Support Unit, The Pituitary Foundation, PO Box 1944, Bristol, BS99 2UB. Please mark your envelope 'DI Card'.

The wording on these cards is as follows:

Due to a disorder called Diabetes Insipidus, which prevents my kidneys from retaining water, I need to use a toilet urgently at times. Would you kindly allow me to use the nearest loo? DI is caused by a hormonal deficiency and is not contagious.

These cards are only available to patients in the United Kingdom and Republic of Ireland.
