It all depends on the specific Candida diet you’re following, and there are hundreds of versions out there, some work, but most do not. A few examples of foods that most designers put on their diet that will prevent your progress are; carrots, nuts, red meat and pork.
The reason your stomach is swollen is because the Candida albicans excrete toxins, namely, aldehyde, ammonia, and ethanol. All of these toxins can cause bloating and constipation.
If your tests came back saying that your Candida infestation was worse, then you’re obviously feeding them, that’s the only reason that the infestation would increase in numbers instead of decrease.
If you’re eating red meat and pork, this is causing extra ammonia to be released in your body. Ammonia is release when both red meat and pork are broken down in the intestines, and ammonia will benefit the environment of the Candida keeping them alive. I have talked with Candida sufferers who have actually caused terrible die-off symptoms simply by cutting out all meat and pork products. You would also be better off if you can reduce the amounts of chicken and fish that you eat in a week because they also release ammonia, just not as must as red meat or pork.
Are you eating nuts or seeds on the diet? Nuts and seeds contain mold which will also benefit the Candida making it easier for them to survive.
The reason you’re gaining weight instead of losing it is because you still have a Candida overgrowth in your intestines. Candida albicans in the body causes fluid retention which of course turns into water weight gain. Candida normally decreases hormonal effects, and hormones control your metabolism and the result is normally hypothyroid. Hypothyroidism causes weight gain. The three toxins I spoke of earlier make losing weight more difficult as they tend to cause the body to hold onto the weight.
You need to look at the label of every single food product you purchase for hidden Candida foods. For example, the only sweetener you should use is either Truvia or pure, raw stevia without any added ingredients. Look at your salt; does it contain iodine? If it does, then it probably also contains Dextrose which is a sugar on which the Candida can feed. Look at your toothpaste; does it contain a sugar alcohol? Brushing your teeth with hot water is better than using toothpaste which is full of potentially dangerous chemicals and sugar alcohols.
If you go out to eat you should be aware of the ingredients that the chefs are using. Many chefs use a lot of butter for flavoring for example, which is going to hinder your progress on a Candida treatment (it’s dairy which means that it contains lactose).
Nystatin and Diflucan may help to lessen the population of the infestation to a degree, but these antifungals, or any antifungal for that matter, are incapable of actually curing a Candida albicans overgrowth. You should probably have a closer look at your diet and go from there.
I would also look into your probiotic and ask yourself: Is it strong enough? Am I obtaining enough strains of bacteria in the probiotic? And does it contain the Lactobacillus acidophilus DDS-1.
