Need a plan of action and a list of tests that you recommend taking to learn more of my malnutritioned body.

My issues in order by finding:

1. Started with double vision. Diagnosed with sixth nerve palsy. Opthomologist sent for MRI.
2. MRI was set as normal but found out I had a severe sinus infection. Opthomologist sent to
ENT.
3. ENT prescribed Predsone for sinus infection and ringing in the ear. Finished two rounds. Gained 25lbs from steriods.
3.5 Started exercising and eating clean
4. ENT mentioned possible nose surgery. Sent to Rhinoentonologist and was seeing Nuero Opthomologist simultaneously.
5. Rhino looked at normal MRI and found a tumor behind eye.
6. Doctors mentioned complications with getting a biopsy in such a tight location.
7. Started looking into testing of other things. Found out, I have a few food allergies and tested high with Candida albicans. How does one remove this?

Need a plan of action and recommendations of tests. Would like to know more on what is happening to my body and overall health. I started keto diet in June; no gluten, alcohol or sugar diet.

How can I stop Candida growth in the gut??

How do we test for low immunity?

What tests should be taken for malnutrition absorption in the body?

What test should be taken to find out deficiency of proteins, minerals or vitamins?

What test should be taken to check overall gastro intestinal health??


Thank you,
