Thank you again for the replies. I quite often don't feel like eating before lunch and get tokd I should eat a good breakfast so I'll go for LadyCGs suggestion.
Squad, yes, some heart failure. I have regular blood tests to check kidneys and, I discovered heart , had a call from a new dr saying something in my blood suggested heart failure, just slightly. Been referred to heart clinic but will have to wait months for an appointment. He said my blood tests had shown this for some time but nobody had picked it up. I have no other symptoms apart from odaema.
