Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain and the medical history of taking antibiotics the coating on tongue can be
Oral Thrush or
Oral Candidiasis..
It is an opportunist
fungal infection and can be caused due to decrease in number of good bacteria of the mouth that resists infections along with the harmful one..
You should
consult a Dentist and get evaluated as the clinical examination is sufficient in case of thrust due to hallmark features of Cheesy white to yellowish coating on tongue..
In case of thrush the dentist can advise you to take oral
Fluconazole or
Itraconazole as they are antifungal medicines.
Nystatin mouthwashes can help..
Antifungal lozenges can provide relief..
Take more of probiotics in diet like Yoghurt and Garlic..
Drink plenty of water to prevent
dry mouth..
Consultation with Gastroenterologist and complete evaluation along with endoscopy to correctly rule out the reason for bulging in intestine and if needed then only antibiotics should be taken as Thrush will continue to relapse in case if antibiotics are taken continuously..
Hope this information helps..
