Thanks I've never heard of candida so that's another thing I can put in the tool bag when I go to the docs. It's hard to narrow things down because the symptoms are all pretty similar for every one of these things but getting tested for them all individually might be my best best.
You would be surprised how many people have gut issues in America, its very common specially as you get older. a lot of women tend to have leaky gut.
you are probably feeding the bad bacteria with your sugar fed diet
If I were you do a cleanse start over diet, eliminate all bad foods and start making BONE broth from animal bones like chicken and beef, boil that in a slow cooker over night to break the collagen and proteins
This is something my family has used every time during flu season and we never get sick, we drink bone broth my mom would make it for us every winter you drink it warm and it is great for the stomach too and immune system.
after those are done fridge it scrap the fat off the top, the broth should be jello consistency
then every day warm up a cup of that stuff drink it, you can also add veggies to it and use it for your base for soups
its great for the gut. after a week or so drinking broths and eating soups you can determine how your gut is feeling, it should help cleanse you too, you can then start including solids back in and good foods
also when you boil potatoes dont eat them warm, wait for them to be cooled in the fridge and then eat them cool you can put bbq sauce on it, for taste but the reason to do this eating them cold is they become a Resistance starch, meaning you wont get a spike in glucose and it will help feed the good bacteria in your colon.
