    I would like a little more information on constipation, the button that seem to take me to the constipation question and answers does not respond. Thank you so very much

    Agree. Did not supply information about constipation that a low carb diet causes..
  3. Linda
    Agree...what’s best solution for constipation??

    You can find information about constipation in the beginner series, or just search it on dietdoctor.com.

    Since starting LCHF 3–4 days ago, I've had diarrhea shortly each meal. (Only one meal a day, in the evening.) I don't see this as a listed side effect. Could it be something else? An adjustment to higher fat? Rebellion to no junk food?

    After experiencing it myself, I researched and read that some people get diarrhea when starting a low carb diet. I had the same experience.. Its normal and goes away, as the body adjusts. Some people get constipated, others like us get initial diarrhea.

    All of my stomach issues have disappeared since doing keto!! I was never diagnosed with IBS officially, but I had a lot of issues. So happy with that!!

    I have been on keto for 3 months. I have successfully lost 27 lbs. I have also gotten off of all my insulin. I'm still on metformin and trulicity. My problem is diarrhea and stomach cramps for the entire time. It is very bad and often through out the day. I do not want to go off of Keto but I don't know what to do. Any suggestions? I do use quite a bit of Splenda. I can't tolerate truvia. I do use dairy products.

    I’ve been doing the LCHF Keto for 6 mths
    Lost a substantial amount of weight
    But my problem is chronic IBS as soon as I’ve eaten I have to go
    To the bathroom and have terrible diarrhea cramps and bloating 😏🙄

    I also don’t want to give up the diet either
    Does anyone else have any remedies please

    I'm 1 month into Keto. Staying true & strong. With metabolic syndrome for a number of years along with IBS. Also having diarrhea issues. YIKES!!
    No going back for me! Keto is my bestie. Increasing water, avacados, fat intake overall. My lifestyle is taking a major hit! Is this a normal side affect due to my umpteen decades of being a carbo-holic?

    I’ve been on keto for 2.5 weeks and i had Mct oil in my coffee and I’ve been peeing out of my rear. Is that dangerous?

    Where are the answers to these comments? I do not see solutions provided by "Diet Doctor"

    I'm just starting and have one concern. I have Ulcerative Colitis, but in remission. I have been on medication since 2009 to keep me that way. I also am on a very restrictive diet to avoid fiber and dairy. I cannot have any dairy, no nuts, seeds, beans, raw vegetable or fruit, and hot spices. Will I be able to go on this diet? I am addicted to sugar in a big way.

    Amanda et Lisa, moi aussi j'ai des problèmes gastrique, pas tous les jours, mais chaque semaine depuis ma nouvelle alimentation. Ce que

    je conseille, est d'écrire tous ce que vous mangez pour ensuite enlever un des aliments que vous soupçonnez d'être la cause

    de vos maux. Mon état s'est amélioré grâce à cela, c'était les produits fermentés, l'une des causes du problème. Là, je crois que se sont

    les produits laitiers qui me causent des maux de ventre et des nausées. Je cesserai ces produits bientôt,et je reviendrai cet automne pour
    vous informer de ma réussite ou pas.

    Does anyone have any answers at all on this thread around the bloating and cramping? I see a lot of folks have the same issues. The diet is great but not worth constant cramping and bloating! Am I missing something? I am almost over week 2 in the Diet challenge. Constnat bloating. Constant cramping and just now beginning to feel tired. Someone please shed some light!
