Welcome in H.C.M.
I have gone through your query regarding yellowish coating over tongue, as you saidthat you are prone for strep throat infection
. You are nterested to know about facts for recurrent throat infections.
Firstly I would like to say that yellowish or whitish coating of tongue is basically due to-
1- Dyspepsia (gastric disturbances).
2- Upper respiratory tract
Your second question is for recurrent strep infection in throat, for this I would like to say, there is possibility of pockets of infection in upper respiratory tract which gives rise to frequent strep infection in throat . This shows that you may be having-
1- Chronic maxillary sinusitis
2- Chronic tonsillitis
All above harbours strep infection and discharges them from time totime. So please get yourself examined by ENT doctor to rule out above and manage accordingly.
