Your doctor can usually tell if you have oral thrush by checking your mouth or throat. X-rays or visual examination of your digestive tract with a special instrument may also be necessary for more serious cases. The signs of a yeast infection are thick, vaginal discharge like cottage cheese, itching and burning. Many women get yeast infections, but women with HIV often get yeast infections that keep coming back. For thrush in the mouth or throat, your doctor will probably give you a special mouthwash, a tablet that dissolves in your mouth or a pill.
Most thrush infections go away with treatment.
The same medicines used to treat thrush are often used to prevent thrush before it appears. However, excessive use of these drugs can cause a form of thrush that is resistant to treatment. You should talk to your doctor about whether taking medicine to prevent thrush is right for you. Also, some changes in diet may help you prevent or reduce thrush. It might help to cut down on dairy products and food made with sugar or yeast.
