pudginess

I'm a little stuck... Click here to teach me more about this clue!

'weight problem' is the definition.
The definition and answer can be both human attributes as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'order gp issued about new' is the wordplay.
'order' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'gp'+'issued'='gpissued'
'gpissued' with letters rearranged gives 'pudgiess'.
'pudgiess' going around 'n' is 'PUDGINESS'.
