Welcome and thanks for posting your query to Healthcare Magic.
As per your query you are diagnosed with "Candidiasis" and it breaks out after eating sweet things.
To guide you better about this condition - it is a fungal infection
caused by the fungus Candida. As per other fungi it also have tendency to grow specifically in humid conditions with excess sugar adding to the growth.
Therefore I request you to first of all go for your sugar check up. Even if the sugar level is normal then it is also quite common to find in normal sugar level also after a particular age. You should eat a less of sugar containing foods.
For complete relief you will be requiring proper antifungal treatment in form of oral and topical treatments by a dermatologist. If the sugar level is raised then it also requires correction by proper medication.
Avocado oil do not have anti-fungal properties so it would be of no help in reducing the problem.
Despite above measures if the problem is not getting better then it is better to consult a dermatologist
for best guidance.
Hope these informations will help.
"With good health wishes"
