I have adrenal fatigue, low thyroid, candida and low hormones and have learned that they are all very commonly related. Dry eyes is a symptom of low thyroid.
If you suspect you have candida, that's probably the most important aspect of your health to get control of. My doctor is giving me supplements for all of my health issues, but is focusing on the candida because she believes that curing that will help balance all my other hormone levels (including adrenals and thyroid . . . as well as DHEA, estrogen and all the rest).
There is a TON of information out there as to how to eat and what to take. My advice is to make a note of what you hear repeatedly.
My doctor gave me a list of foods I can eat, but it is much more liberal than what I see everywhere else. For instance, she allows me to have sweet potatoes and corn, while many candida diet lists say to avoid those. I have, therefore, in the interest of regaining my health as quickly as possible, decided to avoid those foods, at least for the most part. I may get healthy with her diet, but I suspect it will take longer.
Supplements to focus on:
PROBIOTICS (apparently they all work differently for everyone, so you have to find the one that works for you. I'm on Ortho Biotics by Orho Molecular, as given to me by my doctor. I also believe in Primal Defense by Garden of Life, so if Ortho Biotics don't work, I may try Primal Defense next.)
ANTI FUNGAL - I'm on Fungal Defense by Garden of Life
FIBER - I'm on PSYLLIUM (read reviews on Amazon to help choose)
Make sure you are having good stools. The better you digest and eliminate, the faster you will eliminate the bad bacteria and yeast. If you aren't eliminating well, try a different fiber product and/or up your dose.
This site is a good resource, but it can be overwhelming as you get a million sources of information and have to pick and choose what is right for you. Just know that whatever you do, the longer you have had a yeast overgrowth, the longer it should take to get rid of it. Be prepared to settle in for a good while on healing yourself. Eat right and take your supplements and the results should come. Everyone is different in how long it takes. My doc said in 6-8 weeks I should be feeling a LOT better. However, since I know I have had my candida symptoms for at least 15 years, I am prepared for the long haul. I have read it commonly takes 2 to 6 months to rid the body of yeast, and the average is 3 to 4 months. The more strict you are on your diet, the better. Avoid Sugar like the plague.
