As you may know candida is a single-cell fungus and is always present in your intestines and on your skin. If it gets out of control it's called a candida infection,yeast infection or candidiasis.
The most common places it's found is the mouth, gastro tract, fingernails, toenails, ears, nose/sinuses and the vagina.
It has a very--very wide range of symptoms and around the rectum it is mostly itching and irritation. Diarrhea as well as constipation and I could list a page of symptoms ranging from brain fog to diabetes.
BMs are supposed to be formed and I have not had any leakage with a yeast infections but I take psyllium twice daily, don't consume milk but eat yogurt 3 or 4 times daily and take probiotic supplements.
I recently read an article about consuming dairy products will cause some leakage. It talked alot about animals that don't use toilet paper and all have well formed stools and they don't consume milk.
I hope you are taking a water soluble fiber supplement like Metamucil. It's a bulk stool forming agent and is safe to take daily. Most people these days don't get enough fiber in their daily diets. You have to have FIBER for your intestines to function properly---20 to 30 grams daily.
Dairy products and all meat as well as seafood contain NO fiber. So you have to get it with fruit and veggies and we are mostly not that diligent about what we eat--- we mostly eat what we like.
I wish you well---Harry
