Swallowing/ Eating & Drinking

UK based – Our father has been hospitalised with a severe case of GBS (suspected AMAN or AMSAN variant).  Ventilated (tracheostomy) in ITU since end of March until end of May (2 months). Then transferred to a neuro rehab ward within hospital.  The Speech & Language Therapist have been working with him on his swallow & trying to improve his lip seal. Due to extensive research we are aware everyone’s recovery is different, not linear & takes a very, very long time. The speech & language therapist have said our father would benefit from a PEG being fitted as his swallow/lip seal are too weak to enable him to drink & eat.  We are wondering if we could ask what other people’s experience is regarding time scales of when they regained use of swallow/ lip seal & when they were able to drink/eat again?
