A sugary diet. Not getting Mr sparkle treated at the same time. Soy sauce and other yeast-based products. Tight knickers or thongs. Tight jeans. Perfumed soap powder.
should have said, that live yoghurt eaten and administered (cooling) is very good. Also Aqueous Cream to wash with - large tub at the pharmacy counter - quite cheap to buy, lasts a long time as you do not need to use much.
As Pippa says it is horrible, and that embarrassing itch - argh!!
Yeast based foods can act as a trigger to thrush.
A common reason for recurrence is anti-biotics (especially strong doses - taken for something unrelated) which break down the natural body defences against the candida bug. Doctors, when prescribing ab's sometimes mention taking precautions against thrush (if they know the patient is susceptical to it) suggesting live (bio) cultures, and cutting down on yeast products.
