There are a few things Eleanor can try such as cleaning the inside of the nose using a salt water (saline) solution or using a steroid nasal spray or drops – though these need to be prescribed rather than purchased over the counter to avoid a license breach. Opting for bland foods such as steamed vegetables, natural yogurt, noodles and rice rather than strongly-flavoured or fried foods may also help, as can taking exercise to release feel-good endorphins, seeking out distractions in the form of brain-occupying hobbies such as crafts and puzzles, keeping a smell diary to track progress and smell training using essential oils or household items. If eating is very problematic, nutritional supplements may be necessary to bridge any gaps.

An important thing to bear in mind is that having an altered sense of smell means an important early warning sign for the body may be affected. Dangerous smells may be missed, such as a gas leak, a fire or food that has gone off, meaning carbon monoxide and smoke detectors, as well as keeping an eye on expiry dates, are all important. It also means that ensuring adequate ventilation in certain situations needs to become a habit rather than something that happens reactively, for instance when cleaning using bleach or disinfectants that emit fumes or doing DIY jobs such as painting. 

And of course, personal hygiene may be compromised due to a lack of self-awareness, so maintaining a regular routine in terms of showering or bathing, wearing antiperspirant and regularly laundering clothes, which may be better if they are made from natural fibres such as cotton as these tend to be more breathable, is a wise idea.
