It took me about 3 weeks to start seeing the effects. I had IBS symptoms that completely disappeared.

I had many symptoms, I just didn't know they were caused by wheat. I'm not actually certain my problem is gluten, because I don't think I have symptoms from corn. All my symptoms faded over a period of about 3 weeks when I changed what I was eating.

Now, if I eat something containing wheat I have symptoms the next day. They take a few days to clear.

I was diagnosed with celiac disease... GERD, IBS etc, etc. I went gluten-free immediately after diagnosis and it took ten days for me to feel better than I had in a very long time... if I accidently get 'glutened' the effects are pretty nasty and they last from 3 - 10 days (depending on how much gluten I ate) Good Luck to you.

Check out this wikipedia entry.

What is the relationship of gluten and anti-gliadin antibodies?. In gluten-sensitive individuals AGA testing is a routinely used blood test for possible presence of coeliac disease, allergies or idiopathic phenomena.

...

The half life of these antibodies is typically 120 days.

Personally I've seen all symptoms fade in 14 - 21 days after even a large dose of gluten, though considerable relief comes after the first week is over.

I am non-celiac (confirmed by endoscopy); gluten and legumes cause me abdominal pain and bloating. My symptoms went away about three days after cutting gluten. I am not highly sensitive and have to eat fairly large amounts to have symptoms; the longer I've been paleo, the faster my symptoms resolve when I do get them.

For me? 3 days.

Don't a ZILLION things cause chronic sinus inflammation? Have you addressed dust mites and mold and dairy and all that? Don't get me wrong, I think gluten is Satan for most of us, but this could be a reach.

My son's bad rash completely disappeared within a week after putting him on a gluten-free diet.

It took months of being off lots of wheat for me to even realize that I had a problem. Now, whenever I eat lots of wheat, it takes me only 3 days to feel like I am back to normal.

i dont think i have a glute problem just a carb problem :/

I did the gluten challenge & knew when i re-introduced it to my diet w/in a couple days i am gluten intolerant/sensitive.
After a detox (a week or so) & noticed a difference w/in a couple weeks of energy, BM's, skin changes (for the better, which only improved on paleo), even mood was more stable on GF (fewer hormonal swings). HTH

Many with celiac disease report it taking 6 months to heal. Some symptoms, such as psychological ones, can take a year or two. And I've heard people say that if they had other food sensitivities, it can take 1 or 2 years of a gluten free diet to be able to add those other foods back.

I think a chronic sinus infection could take any length of time in between 1 week and 2 years, depending on the etiology. Additionally, there could be other things at play in addition to gluten that would prolong healing, such as other food intolerances or allergies, other sources of inflammation, vitamin deficiencies, etc.

My IBS and joint aches went away in about 2-3 weeks. Heaven!!

90% of my sinus problems disappeared in 3 days when I stopped gluten as well as Sudafed & Claritan, which I had been taking daily for several years for my stuffed up sinuses. Symptoms return in less than 24 hrs if I eat gluten, so that's a good incentive to avoid it.

Most of my other symptoms disappeared in 2-3 weeks, as others have said.
