Hi all. I recently had a course of antibiotics for an infection and routine bloods revealed HbA1c of 42mmol. During during the antibiotics course I developed thrush on my tongue but also had short periods of dizziness which I attributed to the abx. I have finished the abx but still have the coated tongue and occasional dizziness and wake up at night with fast heart rate. I can't get an appointment with a professional for a week but am anxious about what I should do about symptoms. I don't know whether I am prediabetes and these symptoms are related to something else or these symptoms suggest I have already developed the condition. Thanks for listening.
