How Is Diarrhea Due To Infection And Vitamin Deficiency Treated ?

Question: Hi, I'm 48 year old female. I weigh 123lb and am 5 foot 4 inch tall. I have psoriatic arthritis affecting my right ankle only. My specialist put me on methotrexate 5 years ago and has been upping the dose every time I see him, I should now be on 25mg (10 tablets) a week. I finally linked my feelings of depression, brain fog and lack of ability to concentrate and lack of appetite on methotrexate in XXXXXXX and, as I was still in pain anyway I decided to come off methotrexate, last dose 7 July, and try an anti-inflammatory diet instead. I have a business to run and need to be able to think, I just couldn't cope with the brain fog and need to sleep any longer. I started the anti-inflam diet at the beginning of XXXXXXX I have got increasingly better as the weeks pass, particularly after quitting methotrexate.

I started with XXXXXXX smoothies, lots of pineapple and bananas and spinach. Then I added more fruit and started eating a lot more steamed veg, I did this for 4 weeks and was fine, no problem with my bowel. I ate one raw beetroot one night and the next day had diarrhea, that was 12th July and haven't had a solid motion since. I've cut back on the fruit now and only eat gluten free muesli with berries in a morning and beef or chicken with lots of steamed carrots, cabbage, cauli and beans etc on an evening, I stopped taking sugar in coffee. I'm not ill, I feel better than I have for a long time, particularly head wise. I've never had bowel problems in the past but now I get stomach cramps before needing to go - perhaps two or three times a day (mornings are bad) and I seem to have to go not long after eating. There is no blood but what I'm passing is like mucousy, runny and I noticed this morning that there is a lot of undigested stuff in there - clearly carrots and cabbage! I feel I've caused myself a problem and I'm not sure what to do about it. I have no faith in my doctor or my specialist as they will not listen to me - they just want to keep upping the dose of my tablets. I feel this problem has been caused because I changed my diet radically suddenly but now I'm concerned because the food I'm eating and the supplements I'm taking aren't digesting before leaving my body. I have no temperature/fever, no other ill-effects at all, just the need to go a couple of times a day and it's always like fluffy lumpy water, sometimes some gas too. I haven't tried any other the counter medication for diarrhoea yet. Any suggestions? Thank you for your time.
