Vitamin B12 defiency can cause weight loss along with insomnia.. and tinnitus.. and these things often all occur around peri menopause. Are u female in late forties early fifties?

I can attest that Candidate can, and does cause several different issues. Tinnitis : yes, vision issues (blurry/double vision) : yes, insomnia : yes, fatigue : yes, OCD : I don't think I have that one (touch wood), weight loss is a tricky one : I have lost many pounds of muscle but gained many pounds of fat.

parasites and candida caused OCD in my case (pure O), and also caused tinnitus, insomnia and weightloss. Since I've started to get a handle on the parasite issue the OCD (and other issues) is fast fading away, but I am in for a long ride.

Electromagnetic pollution can cause the same symptoms as candida.

The way to mitigate these effects is to avoid wearing your cellphone/smartphone on your person during the day and not having it beside you whilst you sleep, and also to switch off domestic wifi when not in use.
