I think you are misunderstanding. I'm talking about the claim by some in alt medicine that candida can grow so out of control that it can cause just about every known symptom under the sun. Those collection of symptoms they attribute to "chronic candida" is what I am saying is really malnutrition and that's why their are so many symptoms. Malnutrition is mostly likely caused by under-eating, but also by eating too much empty calorie junk food.
Simple candida infections, like vaginal yeast or oral thrush, can be caused by malnutrition or over-use of Antibiotics , but candida is not causing all those symptoms that are identical to malnutrition.
But you should worry about what's causing your symptoms and if you're only getting about 1,000 calories a day, I'm telling you right now, that is the cause of most, if not all of your problems because eating that little will cause malnutrition and all of its associated symptoms in you and that will weaken your immune system leaving you more susceptible to infections like a yeast infection or oral thrush.
