A vegan diet has been mentioned in this forum from time to time. I decided to try it after finding someone on the internet who said she'd resolved her ITP by going on a 100% plant-based diet. The word 'vegan' seems to make people who've never tried it roll their eyes, and I must admit I would never have thought of it had I not found this information.
When first diagnosed in 2012 my platelet count was 4,000 and I was put on a high dose of prednisone. Long story short, it was an awful roller coaster and the side-effects were terrible. In desperation after far too long on the meds I was told a splenectomy was my only hope. I regret that I let the doctors persuade me. Platelets were up for the first few days but then went down to 9,000 again. So I had no spleen and chronically low platelets again. A miserable failure.
We're all told there is no known cause and no known cure for ITP. Once I got out of the debilitating prednisone fog I was in I realised there was a sequence of events that had occurred leading up to my diagnosis. I'd taken a long course of ibuprofen (Advil in the US I think) which I didn't know until later, is known to damage the lining of the gut. It did mine; I had a bleed the last time I took it.
So I had Leaky Bowel Syndrome,which caused a major stress overload on my immune system, the reason, I believe, that it got confused and began destroying my platelets. All this took a long time to figure out, but once I did, I knew I had to mend my gut before anything else good would happen. According to the website of Dr John McDougall, (who recommends a vegan diet for autoimmune disease sufferers) the immune system regards animal protein as foreign protein and sends out the attack squad, thus giving it more work to do.
So I needed to calm down my immune system; give it a holiday from all that warfare. I started cutting out dairy to start with, just to ease into it. I felt so much better in the first week; I was amazed. I did accidentally eat something with milk protein in it one day and my platelets took a dive. Coincidence maybe, but another poster on this forum (Alfonso) has said the same happened to him three times after he ate sausages after not having them for 18 years and he got his ITP back.
I had no idea if this vegan diet would work for me but after eight months of strictly avoiding animal protein I had a result. After a lot of ups and downs my platelets went from 7,300 to just over 400,000 and they have stayed there ever since. Normal! It has been two years now and my immune system is stronger than it's ever been. Despite having no spleen I haven't had any illnesses although the doctors said I would be susceptible to everything that was going around. I am aged 61 and in great health. My arthritis has even gone, so this is good for more than just one autoimmune disease, as Dr McDougall advocates.
They say that 75-80% of the immune system is in the gut so it makes sense to feed it right. But of course every gut is different and what might work for one person may not for another. Having said that, I felt I had nothing to lose and everything to gain by trying the vegan diet. It worked for me and I feel so much better on it. And my platelets have returned to normal which the doctors said would never happen. I don't want to upset my immune system again, and especially not my platelets so I'm sticking to it.
Two things though. You do have to be very determined and disciplined. Falling off the wagon might send your immune system back to its old ways as it did with Alfonso and his sausages. Also it doesn't happen quickly. Your immune system needs time to relearn.
I hope this helps someone, as it has literally transformed my life.
All the best.
