When to take (or NOT take) Probiotics? Thoughts from a GI Fellow

Probiotics have a lot of potential but right now the level of data is not overly convincing and therefore the AGA only officially recommends probiotics in certain circumstances. Please remember this video is only intended to be for educational purposes and is NOT intended to be medical advice. Always talk to your doctor since they know your specific health history best

    This is really helpful! I’m on biologics for my RA and have considered it for whenever I go on antibiotics for various infections. Are probiotics in yoghurt still good to support gut health?

  2. JessScreams on September 12, 2022 at 1:04 am

    Lol I got an ad for a probiotic on this video

  3. Chesterson Jack on September 12, 2022 at 1:08 am

    Despite your uniform, my mind didn’t connect that you were talking about medicine and was wondering what this meant for the 4-5 prunes I eat every day.

  4. Laura Douglas on September 12, 2022 at 1:08 am

    I like vinegar drinks and Kefir and yogurt.. I have Hashimoto thyroid.. is this ok for me ..?? Love your videos❤️

  5. Cheryl VL on September 12, 2022 at 1:09 am

    Take probiotics during and after antibiotics!! I’m 47 and caught C. diff the day I was done my 10 days of antibiotics.

  6. Lizz Wilson on September 12, 2022 at 1:09 am

    Did not know probiotics weren’t recommended during pregnancy!

  7. SMS W. on September 12, 2022 at 1:12 am

    Thank you for saying that the lack of info doesn’t mean that they aren’t dangerous. It just means that more research needs done. Because 10 to 15 years ago I heard that there was no evidence.

    Finally, it seems like research is actually happening. But, I heard that "lack of research." Then I’d go home and check at NIH. Not a single study on probiotics or any other CAM, but a thousand studies into whether fibromyalgia was real or just a massive movement toward a "lifestyle choice/laziness."


    That’s what happens when you fetishize a single research method over all others. It means you have no evidence on anything that you can’t chop up into the size and shape of a sugar pill.

  8. Lídia Ghellar on September 12, 2022 at 1:14 am

    One question, doc: when you refer to probiotics, do you mean capsules or “naturally”ocurring ones, like in yogurt or kefir? Are their effects/concentration different?

  9. atlaslex on September 12, 2022 at 1:15 am

    I don’t know about whether there are any scientific studies about this, but most people with vaginas will tell you that taking probiotics with antibiotics is pretty key 😂

  10. Jarred Lozano on September 12, 2022 at 1:16 am

    What about fecal transplant 🤔

  11. Catherine Rosa-Baker on September 12, 2022 at 1:16 am

    My doctor said to take probiotics.
    I have nothing wrong with me.
    I used to eat yogurt with the live culture but I can’t eat yogurt anymore. Probiotics are good bacteria to fight the bad bacteria in your gut, right?

  12. HH on September 12, 2022 at 1:16 am

    I took alot of probiotics for a month and made my General Anxiety go away.

  13. Brian Smith on September 12, 2022 at 1:17 am

    So don’t if you’re HIV positive?

  14. Nicole26 on September 12, 2022 at 1:19 am

    Can I take probiotics while breastfeeding?

  15. Alexander Danklad on September 12, 2022 at 1:19 am

    How do I grow probiotics from pills can I use fiber and sugar

  16. Maria .A. on September 12, 2022 at 1:19 am

    So if the AGA won’t recommend pro-brobiotics because of "lack of evince" then why don’t they do the research? Pretty sure big pharma helps fund them and is probably against the research. Big pharma can’t get rich off of probiotic vitamins so…. there you go.

  17. First Name Last Name on September 12, 2022 at 1:21 am

    Does eating yogurt with antibiotics help?

  18. Makinoodle on September 12, 2022 at 1:22 am

    What kind of doctor are you

  19. Lauren Farnsworth on September 12, 2022 at 1:22 am

    People love taking probiotics because they have GI upset then say “I don’t know what to pick theres so many options!” … I don’t know man just pick one

  20. Arjun Patel on September 12, 2022 at 1:22 am

    Thoughts on requirement of prebiotic along with probiotic? What about inpatients on antibiotic especially those on flagyl?

  21. Corinna Butler on September 12, 2022 at 1:24 am

    What is high risk?

  22. Gina Simpson on September 12, 2022 at 1:25 am

    Sooo much information, i literally watch your videos minimum of three times, just to take it all in 😬
    Btw, you talk really fast, lol
    Thank you for your educational videos
    Good 👍

  23. الـحـمـد لـلـه on September 12, 2022 at 1:25 am

    السلام عليكم؛ ياليت احد يترجم لي ماذا يقول هذا الطبيب؛ هل نستخدم البروبيتك ام لا؟

  24. Carol Gary on September 12, 2022 at 1:25 am

    ANTI-biotics, kills *ALL* bacteria – good & bad.

    PRO-biotics are good bacteria, but, if you take at same time as ANTI-biotics:

    ANTI-biotics will kill good bacteria of PRO-biotics.

  25. lasercats on September 12, 2022 at 1:26 am

    I’m a primary care doctor and if anyone comes up to me and asks about these things you told them to ask to their doctor to, I’m going to be very sad.

  26. Gianna on September 12, 2022 at 1:27 am

    Me, taking antibiotics and probiotics together on a doctor’s recommendation: Now FIGHT!!

  27. JellyDemoniccck on September 12, 2022 at 1:27 am

    Great info, but slow down. Just. Do it.

  28. Gabrielle C on September 12, 2022 at 1:29 am

    What are your thoughts on taking probiotics specifically for helping get rid of cervical dysplasia/CIN?

  29. TheBean2p on September 12, 2022 at 1:30 am

    My husband is ALL about probiotucs but I’ve always been meh about them. I have taken them but I’ve never seen any difference. However, when I upper my water intake, well thats when I noticed a difference.

  30. Maggie & Matty on September 12, 2022 at 1:30 am

    Hey I have a question I take steroids for very high testosterone so should I take probiotics

  31. Alicia Scott on September 12, 2022 at 1:30 am

    Showed Mother this video. She eats the yogurt and capsule in fridge. "It makes me poop." She is 3 yrs post breast CA. AND she has a condition where her lower GI is twisted. They can’t scope her. I am thinking she should be careful with the probiotics.

  32. seriously? really? on September 12, 2022 at 1:33 am

    We went on a 2yr trial of Dannon probiotic yogurt (or kefir when we had supply shortages) BID to just about all of our ICU patients ( recommended by the dietician) because virtually everyone was on antibiotics. Then it stopped. Can’t say why. Can’t say whether it reduced the statistical incidence of c-diff on our unit. Questions that got put on the back burner due to our prioritizing covid response… be willing to bring the questions back up when the dust settles.

  33. Zoe Rivera on September 12, 2022 at 1:33 am

    Doctor you just answered my question of I should take them. I’m immune suppressed due to having a liver transplant as a baby. Been on anti-rejection med for 29 yrs! Thank you Doctor!!

  34. diosadelrawk on September 12, 2022 at 1:33 am

    Got a question. Im 39 and got my appendix taken out about a month ago. Ive read that appendix holds good bacteria.Should I be taking probiotics? Thank you for taking the time to read my comment

  35. The Kind Potato on September 12, 2022 at 1:34 am

    Yogurt yogurt and antibiotic

  36. Katherine Krueger on September 12, 2022 at 1:36 am

    Are probiotics a good idea for type one diabetics? Or individuals with IBS? Thanks!

  37. Daniel Dionne on September 12, 2022 at 1:36 am

    Glad you’re sticking to what you know instead of instructing others on how they should react to COVID. That goes for foot Barbie as well!👏

  38. flareontoast on September 12, 2022 at 1:41 am

    I grew up being told that if I am taking antibiotics I should be eating more yoghurt etc because women/afab people are prone to developing yeast infections because the antibiotics will throw off the body’s natural bacteria levels.

  39. Brianna on September 12, 2022 at 1:43 am

    Really helpful, I’ve been immune suppressed with multiple made for a while and have had to be given antibiotics and suggested probiotics from drs. Do you have any sources for probiotics linked with infection that you could send/share. Or the specific recommendations about immunosuppressed and probiotics?

  40. Classical Gas on September 12, 2022 at 1:43 am

    What!? There are reasons not to take probiotics?! Is Mast Cell Activation Syndrome one that you shouldn’t take probiotics for?

  41. Jesca Pilar on September 12, 2022 at 1:44 am

    Also what many people don’t know is the TYPE of probiotics is very important. People tend to take any kind thinking they are all helpful, when really there are a handful of them (that very frustratingly are in a lot of mainstream and popular products) that actually INCREASE INFLAMMATION and cause even more gastric distress than help! So research what you put into your body!

  42. Veronica Smyth on September 12, 2022 at 1:46 am

    I will Never touch anything with a probiotic again.

  43. Nicole Bergeron on September 12, 2022 at 1:49 am

    I think it’s really great that you put this in for people to watch. I was recommended to start taking probiotics years ago and it has helped me tremendously. On the other side of things I was never given any instruction on when not to eat something with probiotics or take probiotics. I’m currently suffering from COVID-19 (thankfully I have been fully vaccinated; go figure I was waiting until January to get my booster) and am on Prednisone. It’s great to know that yogurt isn’t the best idea right now. The last thing I want is a blood infection. Thanks for the info doc!

  44. User Not Found on September 12, 2022 at 1:50 am

    Yeah, I take 4 200mg antibiotics a day so my doctor put me on probiotics and other vitamins since I’m not supposed to get fruits or vegetables (which I fail in doing. It is so hard to avoid these and have good food)

  45. Jelly Eons on September 12, 2022 at 1:52 am

    Oh yea I took these before to treat some food poisoning I had gotten due to me being dumb And eating a salad with day old ranch (aka ranch that went bad)

  46. Addie2422 on September 12, 2022 at 1:52 am

    I have ibs and have been trying a probiotic for the past couple of days. None of my symptoms have changed. How long should I keep taking it?

  47. Louise Macleay on September 12, 2022 at 1:53 am

    Absolutely yes. Especially after antibiotics. I wouldnt ask my dr. I know my body.

  48. Jodi L on September 12, 2022 at 1:54 am

    I have a question about probiotics. Over the summer I got c diff from taking an antibiotic because I was septic from a bladder infection and had ischemic colitis all at the same time. I was in the hospital for 5 days to begin with then 2 days when I had c diff. The infectious disease doctor told me that I needed to take Florastor probiotics 3 times a day. Since July, I have been getting bladder infections every couple of weeks and now they are becoming antibiotic resistant. Could taking the probiotics be what’s causing the infections?

  49. Winter Night on September 12, 2022 at 1:56 am

    Thank you doc! My whole family struggles with autoimmune issues and we also all have IBS Crohn’s excetera and several of us have found that probiotics help us with the symptoms of those disorders. However I will warn my family that if they get on medication such as high-dose steroids for bad flares that they need to stop the probiotics. Thank you!

  50. Jenny Evely on September 12, 2022 at 1:59 am

    I’m in trouble then.. yogurt daily. .brain cancer yes
