I'm so glad I found this site! Like many of you I was desperate to find some relief from chronic sinus polyps and infections. Special thanks to Brian of So. Australia for the low carb diet posts and Bryan of Houston for the lecithin suggestion. Your posts really helped me with my sinus problems and started the healing.
My background: I've had Samter's triad (nasal polyps, asthma, and aspirin/salicylate sensitivity) and many allergies for most of my life. I've had several sinus surgeries, chronic sinus infections, polyps deep within my sinus cavities, total loss of the sense of smell, and round after round of antibiotics and steroids to clear up severe sinus infections, only to start again with the next serious sinus infection that was always right around the corner.
What worked for me after about 6 weeks:
A ketogenic diet, this is a high fat, moderate protein and low carb diet. Pretty much the only carbohydrates that are allowed are dark, leafy greens and non-starchy vegetables. To make up for the reduced carb calories, you eat LOTS of delicious fats: extra virgin olive oil, coconut oil, butter, bacon, and cream. Library books I found helpful: "Keto Clarity" and "Primal Body, Primal Mind." Google "ketogenic diet" and search on you tube. There is lots of information on this diet pro and con.
All I can say is that it made an amazing difference for me. The daily gallons of mucus just dried up. After several years of not being able to smell any odors at all, I can smell the coffee in the morning and can actually enjoy the taste of food again! Before I found the ketogenic diet, I went the anti-candida and low carb route, but I think it was still too many carbs for me. Low carb never killed the appetite and the carb cravings like the keto diet did. I'm never going back.
At the same time I started the ketogenic diet, I started taking the lecithin and ginkgo biloba supplements suggested by Bryan of Houston. Twice a day I took the following: 1200mg sunflower (non GMO) lecithin and 120mg of the ginkgo biloba extract. I didn't get Bryan's dramatic 2 week results, but my sense of smell is finally back and I'm grateful.
What didn't work for me:
Be gentle with the tea tree oil and hydrogen peroxide as both can be a little harsh, so you might want to start with a diluted dose until your sinuses adjust and/or heal. I just use sea salt in a neti pot morning and evening to wash the sinuses. I tried the above, but didn't like the burning feeling and didn't feel any improvement to stick it out. Also, be careful of rinsing out your sinuses and tilting your head back and down to move the rinse deeper into the sinus cavities as it can force the liquid into your eustachian tube.
Hopefully I can get through the winter without a sinus infection?that'll be the real deal :>).
