Gas and Diarrhea from Vegan Diet

by JJ
(Bozeman, MT)

Question:
I have been eating vegan for the past few weeks because of a few books that I read that convinced me to do so. I am ready to give up because of the gas, pain, bloating and diarrhea I am experiencing. My friend told me to wait a week until my body adjusts and its been a few- it seems to be getting worse. The diarrhea has gotten so bad that I am afraid to leave the house. I tried to stop eating beans and legumes and that has not helped and don't I need to keep those in my diet? Please help I am about to give up!

Answer:
Don't give up! First of all, your friend is probably right; it often takes a few weeks for your body to adjust to a new diet. It's hard for me to tell exactly what's going on without knowing what you used to eat and what you are eating now. However, in many cases, people who go vegan are eating way more fiber than they ever ate as non-vegans, and that causes the body to pass more excrement than in the past.

I know this is a huge pain, but it's actually really good for your body. You are most likely getting rid of things that have been stored up inside your body for a long time and that aren't contributing to your health. It's sort of a way of detoxification inside your body.

If I am too late with this response and you already gave up, don't fret. You can always go back to it. And, I would love to be able to help you more with more specific information. If you'd like to add comments here on what you were eating before and what you eat now, that would help me to help you (and it would also help our other readers to grow as well). Or, if you'd rather be private, feel free to email me directly.

same problem
by: Anonymous

I gave up after week 3. I was already a vegetarian, and had used milk alternatives for a long time, but I was still eating yogurt, cottage cheese, and some low fat cheeses like feta a few times a week. I had such horrible gas and diarrhea after going strickly vegan that I added back in the yogurt and cheese. I wonder if it is the lack of probiotics in the vegan diet...

Foods and their reactions
by: Christy

I also have occasional bouts of loose stool but what has helped me some is to keep a food diary do I can track certain foods and their combinations to look for a correlation. I have read that the body detoxes and "resets" itself for three months before settling into this wonderful way of eating.

I recommend exploring new foods. When you step back for a day and eat animal products, you reintroduce the toxins and my guess would be that the detox phase only gets longer. I'm not an expert either. I've been vegetarian for a year and a half and just kicked the dairy habit a couple of months ago. I recommend reading books written by doctors and researchers. It is important to explore the experiences of others who are novices, but we must base decisions in facts and research, not guesses or opinions.

Problems with Vegan
by: Anonymous

You really need to listen to your own body guys and gals. The vegan diet is the best diet out there but nothing's perfect, and the vegan diet is not an exception. HOWEVER, this diet's deficiencies can be taken care of by compensating for them.

Deficiencies:

Vitamin B12: Supplement, Mushrooms, Nutritional Yeast, B12 fortified food, brown rice

Omega-3: GROUND Flaxeeds (whole not oil)

Iodine: Sea vegetables (watch out not to over do it) - too much Iodine is also too much

Calcium: Supplement or calcium fortified food

It's mostly important you are not B12 deficient. And Calcium itself helps with diarrhea while Magnesium is the "opposing" mineral which helps with constipation.

Also do not forget the traditional food pyramid (less non-vegan food). Vegans do not just eat the recommended NINE fruit and veg a day (fyi: white potatoes and iceberg lettuce do not count as veg) which MAY be causing some diarrhea. Do not forget the all important grains - whole wheat bread, brown or red rice, quinoa, bulgur, pasta, whole grain cereal (all bran or similar, fruit N fibre or similar, oatmeal are the only decent ones). These keep stools more consistent. Then there's nuts - especially walnuts, almonds and hazelnuts (do not over do it however - a handful a day is more than enough).

You might also be having IBS symptoms. Ginger helps with digestion, digestive enzymes too. Remember that diarrhea is caused by the intestine not having enough time to absorb the water in your stool. By not favouring maximal digestion in your stomach, whole food moves along into the small intestine, and then to large intestine. The more indigested the food, the quicker it will go through you. This will result in more gas produced by your intestine bacteria feasting on this indigested food, and more liquid left in your stool.

So remember, chew very well (recommended 50 chews per morsel), do not drink liquids (water, juices, non-dairy milk, fruit..yes they are loaded with juice) during and until 45 mins after you eat.

Beware quantities of fibre should be increased in increments. And for diarrhea focus on soluble fibre.

Good luck!

I also have diarrhea and gas
by: Anonymous

I have been a "vegan" for almost three months now. I've kicked the dairy and meat(chicken and mammals) habit quickly but I've also enjoyed fish (mostly sushi)occasionally.Now when I have sushi I've opted for the vegetarian roll over the dragon roll.

I started my vegan quest after watching the documentary Forks Over Knives. My family has multiple diagnosis of diabetes, cancer, and high blood pressure. Realizing the benefits of a vegan diet and seeing my own health at risk, I decided to make an instant commitment to myself.

Despite the pressure from my family mostly to convert to my omnivore life, I've been doing really well with the decision I made. I noticed after about a week of my diet change that I had constant bowel movements and contributed this to the detoxing. Eventually everything regulated and I was able to go outdoors again. Recently however, for about a week now, I've been eating rather poorly. Due to a shortage of brown rice, fresh vegetables, and tofu (while my family ate pork chops) I've been confined to eating white rice and beans (black beans and chick peas). I cook in a wok and use about a teaspoon of olive oil. I also use fresh garlic in most of my meals. I've also had salad prepared by my school's catering company and vegetable sushi. I've also taken quick fruits such as bananas and apples, and for breakfast I've had waffles or oatmeal with sundried cranberries, almonds and brown sugar.

Realizing my diet this week has significantly lacked in all of the fresh green leafy vegetables I would normally have with each meal (I have had some canned green beans etc), I've taken a one-a-day vitamin to try to supplement where I've been lacking. I'm happy to say that the vegan friendly food is back in the fridge =] .

HOWEVER.. the constant up and downs of being lightheaded and gas pain is quite uncomfortable. This week I've gone days without a bowel movement and then days of diarrhea and gas pain. I'm not sure that I'm doing my body a favor if I'm in constant pain. I've seen some of the pounds shed off, but quality of life has become an issue. Any help would be greatly appreciated!

Things I frequently eat: Whole wheat pasta, peanut butter, strawberry preserves, rice (brown and white), black beans, chick peas, salads, oatmeal, tofu, broccoli, spinach, Swiss chard, garlic, onions, mushrooms, peppers , etc.

Not quite related
by: Anonymous

I can't really offer much advice. I myself have just turned vegan 2 weeks ago - so i am far from an expert. I also came to this page in search for a solution to the same problem you are experiencing and also suffer from IBS. They are therefore possibly related - as you say - something with the fibre. This is not to say fibre is not good for you, but IBS people are very sensitive to the quantity and type of fibre. Insoluble fibre tends to result in loose stools, while soluble fibre results in the opposite. I can suggest minimising insoluble fibre and add it slowly till your diet till you reach the optimum balance.

What got me to answer is mainly the comment someone made on kombucha tea which I am sure was made with good intention. However please check out this nutritional video. I hope it's the right part, and sorry i dont remember at which point kombucha is discussed, however beware - kombucha is NOT good for you:

Have to give up
by: pat

I have been a vegan for over a month now and the gas, bloating and runs have just gotten worse instead of better. I can't tell if it's the increase in fruits and vegetables or the whole grains, but life like this is terrible. I'm afraid to go anywhere because I might not find a restroom available. I tried an experiment and ate some fast food and for that day, the diarrhea stopped. I am 71 years old and a diabetic and I can't stand this any longer. I am convinced it is a healthier way of eating for most, but the cost to me is too steep. I don't like the idea of going back to meat but I am very tired of this. I have to find some kind of compromise.

RN Vegan
by: Anonymous

Hey guys, while it is a common response to have diarrhea at this stage, please be careful and know when to go to your doctor. If you start to feel fatigue, weakness, or exhaustion, please go see your doc asap because you're probably dehydrated, which is horrible for your body. It's no big deal, you can ease into this way of eating a gentler way, but don't put your body through too much believing that the suffering is your bodies way of detoxifying. It might be your bodies way of saying it's going through too much.
Be vegan, and be careful :)

ME TOO
by: Anonymous

I have been a vegan for two months now and am still getting diarrhea but it feels like it's detoxifying and I feel great otherwise. I eat lots of soups and raw veggies. Chips are my bad food. I have so much energy and feel good in my body. But the diarrhea is a little concerning since it's been happening for so long.

Previous to my change of diet I felt like 'resting' all the time. It's a bit confusing that I feel great now but my body is acting sick. Could this really be just cleansing? After so long?

long term vegan suddenly has diarrhea
by: Joe

I've been vegan for about 8 months and suddenly just this past month I've been having bad gas and this past week or two diarrhea every time I poop! I don't eat wheat. Though I eat whole grains. I eat legumes, veggies, enriched soy/rice milk, nuts, seeds, fruit. I take a weekly calcium and B12 supplement and daily a drop of iodine. Usually my means consist a day of salad, stirfry, whole fruite or smoothie and morning porridge.

The only recent change I've done to my diet is changing the rice part of my porridge for quinoa.

Is diarrhea always a sign of detoxifying or could I be sick?

Thank you! <3

Reason
by: Marc

Well I would go Vegan today if I had an answer to this problem, Same as others I know. If I give up the Vegan Diet just 2 days and go back to my steak and egg breakfast an other meat or fish for dinner it will go away within about 16 hours. I have tried every combination of vegetables and Vegan frozen fake foods and fake meats. They all hit me the same way. My freinds have the same problem, some not as bad.

Now it's been a week that I'm suffering daily from gas and diarrhea...I do really hope it goes away coz I can't eat meat anymore!

Gas and Diarrhea on Vegan Diet
by: Anonymous

I'm sorry to hear about your issue. But if you have been having diarrhea for over a week, you should go straight to the doctor no matter what the cause. You could be dehydrated or have a serious allergy. Sometimes when trying new foods or eating ones that we have not in a long time they could disagree with our immune systems or digestions. I have never had digestive issues from changing my diet but, I am allergic to certain preservatives put in some packaged foods. Medications I have taken have damaged my stomach lining and I have mistaken it for vegetables. I did not find out the real culprit until I went to a Traditional Chinese Medicine doctor who gave me herbal supplements to cure it. Maybe you should try to eat one type of food at a time to see if you can pinpoint exactly where the problem is. Remember that a lot of people are allergic to a lot of common foods today than they were before the modern method of food production came into existence. Try to eat mostly local or organic while your trying things. Good Luck!

PS
I get stomach acid when I drink or eat certain things but, I don't get stomach acid from those things when I have had raw Kombucha tea. Kombucha really helps with digestion and maybe you can try it, just make sure that it's raw. You can get it at Whole Foods Market or a health food store.

Not giving up!
by: JJ

Thank you for the answer- I don't know anyone vegan except for a friend in another state. I haven't given up- there is no way I will be able to go back to eating meat after everything I have learned and am learning. Its just frustrating to hear how this is the best eating plan, how it gives you energy and makes you feel great and I haven't felt this horrible in a long time. I did some research and I think I am having bouts of IBS. I used to have it in college (from alcohol consumption and lactose intolerance) but since I stopped eating and drinking those things over 10 years ago I forgot I had it. I think the IBS is aggravated by the amount of fiber- particularly the insoluable fiber. Today I took immodium and I am feeling better. I am laying off the legumes and beans and also wheat which doesn't leave me with too many options which is frustrating. I don't know how I will get the protein without it. My stomach is in constant distress but like I said I will not go back. I still cook meat for my family- it would be easy for me to eat it- but no way! I am hoping one they will follow my lead. It is really hard because everyone in my immediate and other family think I am crazy and don't understand any of it. They would truly be happy if I didn't continue. How do I email you?
