Treat endlessly knocked back -- can it lead to indigestion? (5)
I believe the answer is:
colic
'indigestion?' is the definition.
(thesaurus)
'treat endlessly knocked back can it' is the wordplay.
'treat' becomes 'chocolate'.
'endlessly' indicates the central letters (the ends of the words are removed).
'knocked back' is a reversal indicator.
'can it' becomes 'ci' (this might be a standard abbreviation which I don't know about).
The centre of 'chocolate' is 'col'.
'ci' reversed gives 'ic'.
'col'+'ic'='COLIC'
'lead to' acts as a link.
Can you help me to learn more?
(Other definitions for colic that I've seen before include "Abdominal pain spasms" , "Abdominal pain, especially in infants" , "unpleasant gut feeling" , "Abdominal pain suffered by babies and horses" , "Abdominal pain from wind or obstruction" .)
