Sophie Willis, a 25-year-old suffers from mast cell activation syndrome and her life is blighted by an allergy to all food, except rice and vegetables.
Her condition causes blood cells to inappropriately react with certain foods and fragrances.
The rare condition, striking around one in 150,000 people means she can go into life-threatening anaphylactic shock, break out in rash or have swollen lips if she has a reaction.
The wedding veil designer, from London, cannot consume yeast, meat, fish, diary and preservatives. She is also affected by sunlight and thunder.
Willis, who takes 60 pills a day to combat her condition, said: 'I cannot eat anything but vegetables and rice, if I eat any other food I collapse and go into anaphylactic shock.
Before being aware of her condition Willis would usually end up suffering allergic reactions for up to seven times a day.
Willis, it turns out, used to lead an active lifestyle, running half marathons and regularly dining out with friends, before falling ill in 2014.
Her condition baffled doctors and, over the next two years, she visited more than 30 hospitals across the country desperate for a diagnosis.
Finally doctors discovered in August 2016 that she had two underlying conditions, a connective tissue disorder called EDS and a heart condition called POTTS, which are common in people who suffer from MCAS.
Mast cells, a type of blood cell, react to foreign bodies and injury by releasing a variety of chemical mediators, such as histamine, in order to fight infections.
In a person with MCAS, the same chemicals are inappropriately triggered causing allergy-like symptoms.
According to Willis, when she eats certain foods, the mast cells in her body react badly and combined with her other conditions causes her to pass out.
Miss Willis claims that sunlight and loud noises also affect her....
