Brief Summary
Hereditary Haemorrhagic Telangiectasia (HHT) affects 1 in 5,000 people. The purpose of this study is to provide data regarding the diet and nosebleed frequency using a questionnaire. This will be filled in by people with HHT. The questionnaire has been designed in paper format.

Outcome Measures
Primary Outcomes (3)
Number of Participants That Achieving Personal Recommended Intake of Iron
Dietary food item iron content assessed by the European Prospective Investigation into Cancer and Nutrition (EPIC) food frequency questionnaire. This method has been validated against the gold standard for dietary assessment, a 7-day weighed food diary. Questions are asked about consumption of 130 major food items over the previous year, requiring participants to indicate the frequency of consumption, and to provide details about the methods of cooking, type of produce, and use of dietary supplements. The EPIC FFQ has been widely validated in a number of studies and is deemed an adequate assessment tool to assess dietary intake.
1 year
Nosebleed Severity
Nosebleeds were quantified using the validated Epistaxis Severity Score (ESS). The six questions provide an objective measure of nosebleeds: three relate to different characteristics of typical nosebleeds within the previous three months (frequency, duration and intensity (gushing/pouring or not)), three to medical attention, anemia and transfusion requirements. The final ESS score ranges from 0-10, where a higher score equates to greater blood losses.
3 months
Number of Participants That Achieving the Hemorrhage Adjusted Iron Requirement (HAIR)
The hemorrhage-adjusted iron requirement (HAIR) was calculated as the sum of the normal recommended dietary iron intake, and requirements to compensate for non-menstrual blood losses.

Study Arms (2)
Diet and nosebleed questionnaire
EXPERIMENTALParticipants will only be required to fill in two paper questionnaires, one on dietary history, and one on nosebleed severity.
Weighed food diary arm
EXPERIMENTALParticipants will be required to weigh their food for one week to generate a food dairy, and have a single blood test, in addition to filling in the two paper questionnaires, one on dietary history, and one on nosebleed severity.
