Untreated mouth thrush

Hello

Was researching candida and saw that steroid inhalers can causes systemic fungal overgrowth. Just realised I've had thrush from my inhaler for at least 2 years now.

Can someone tell me if the untreated thrush in my mouth could have caused candida overgrowth in my intestines?

My symptoms are:

Blurred vision
Excessive and uncontrollable gas (worst symptom)
Constant colds and sinus trouble
Exhaustion
Bit of Depression and lack of interest in anything
Anxiety around crowds
No concentration

Thanks
