Has Anyone Experienced Sudden Banana Intolerance?

by (1192) Updated January 12, 2014 at 2:56 AM Created August 09, 2011 at 1:24 AM

Is there such a thing as developing sudden intolerance to bananas?

My wife loves bananas, but has been unable to eat them for a few months without severe gut cramping and a sprint to bathroom with a toddler chasing after her. The other latex fruits like kiwis and avocados don't have any negative effects. Also the symptoms of fructose malabsorption don't fit the case either. Is this some kind of intolerance that can build up over time after cutting out major problems like gluten?

Thank you.

I have had banana intolerance for a while. I used to eat 1 banana everyday (I now know that we you eat too much of a food you can become allergic) until I ate an banana that wasn't fully ripe. Then I got some nasty stomach cramps and felt unwell to the point I thought I was gonna faint. I understood it was the under ripe banana. A couple days later I had a piece of ripe banana and the cramping started again. I didn't eat bananas for the next 6 months or so (did some gut healing in between (food allergies involved here but not to bananas)) and I was able to reintroduce bananas again in my diet. Hope this helps a little.

Yeah, I stumbled upon a sight called 30bananasaday.com and suddenly found myself ill from the mere thought of one ;)

Is she by chance allergic to latex? There are a group of foods related to latex and you can have an allergy across the board or just a few. I can't tolerate bananas, cooked tomatoes, wheat, potatoes, tropical fruits, and for a time avocados. I've also had issues with foods I've eaten a lot of over time. A lack of cycling can bring on intolerance. That's how I was able to go back to having avocados. None for 6+ months.

Under ripened bananas can be a source of indigestible fiber. She should consider eating them when very ripe - blackened skins and almost opaque flesh. We are accustomed to eating them too young.

I recently went to the doctors with complaints about my stomach cramping, I told them I get acid reflux they presumed this to be the cause of the problem. I used the medicine they gave me and cotinued eating what I was already eating. The cramps persisted and they were quite severe lasting up to 5 hours at a time, next they gave me an antispasmatic for my stomach, this didn't solve the problem just created more giving me constapation, so they ended up perscribing me a laxative to get me back into the usual routiene.

I started thinking whether I am allergic to anything, I though it was dairy first, so I reduced my yogert and cheese intake...no effect. Then I though it might be protien shakes well I havn't had them since so I cannot entirely rule them out. After 2 weeks of having no problems I had a McDonalds and the issue resurfaced. I had a burnt double cheesbuger and a mango smoothy. A few days later I had a banana (slightly greeny) and the issues has again re-emerged to a small degree, my stomach feels achey, the acid reflux appeared and im having those sick burps. I have got my suspicions that it is Unripe fruit but namely Bananas and Mangos which seem to be tied together from what I've seen in these forums regarding latex fruit.

I'll retry very ripe bananas this time and protien shakes and see what happens, if very little or nothing happens my suspicions are confirmed. I would never recommemend not gong to see your doctor about issues but in this case they are more clueless than me and have caused more problems that good mainly constipation and 3 unnecessary costly percriptions. thanks for reading and hopefully this heps someone else out in a similar predicament, Ben.

I have an intolerance to bananas, grapes/raisins, kiwi, pineapple, raw spinach... those are the ones i know of... i did the research and its an amine intolerance... ur body lacks the ability to break down the proteins in that particular food... i hae found there is an enzyme availabe to take before eating the foos but im just leaving it alone

Don't know if this will help any one, but last year I also started having this. I thought it was just weird every other time i ate a tiny bit of banana it would set off my tummy. At one time it was so bad i wanted to call the emergency services out at 2am.

After today's bout, which now i have confirmed, my manager made a lovely cake and she used banana as the filling, i have it ago, within 1 hour it had started. took 4-5 hours to wear off and that point i couldn't tell if i was hungry either.

Any thing with peppermint oil or peppermint will normally ease within 30 mins to an hour. I ended up buying Rennies today, or even senokot which also works.

According to a doctor, it can be the digestive system which will not digest for some reason. Also found out that it's better to burp, do not be sick as it'll make you worse. in the uk classes us "common ibs" or even better constipation this also the same, as i know once i been, I feel tons better but it's just that waiting time till which is awful.

Drink water if you can, i tried to eat my food today and it was in waves!

I'm not aware that i'm allergic to any thing else or intolerance, but funny thing before i used to eat bananas up to about 2 years ago and have a milkshake too.

it's not stomach cramps, it's muscle spasms which occur.

hope this helps x

also, don't eat over 9pm, (Otherwise not sleep and very pain full) I rated mine today, 8/10, and if you sleep 20/10 painful!!

I found this article because I was googling sudden allergy to bananas for myself. When I was a kid, my grams used to always put bananas in my cereal and I could remember a slight tummy ache but it wasn't like I had it every breakfast. Once I got older I didn't really go for bananas, I'd rather have apples or strawberries in season but right around when I was about 22 or so, I had a strawberry-banana smoothie with my boss because she was pregnant and having smoothie cravings. By the time we got back to work, I was having trouble breathing. I went to the ladies room and there was a welt on my face like I have been slashed with a whip or something. I was feeling feverish and had to ask to leave early. As I rode the subway home I was feeling a little weak at first but I didn't suspect I was going in to shock. A few stops from my get off, I started having trouble breathing to the point where each breath felt like I was barely getting oxygen and I was really ready to panic but I had grown up with asthma and I know the best way is to try to stay calm which I did. I guess it was pride that didn't let me freak out and ask someone for help but anyway here we are and I'm fine lol. Back to what I was saying.. I got off the subway and headed up to my car, I think I was never so glad to see a elevator that day, since I had parked on the top floor. Got in my car and called my grandma to tell her what was happening. Her house was near by so I went straight there and she had to shove a benedryl into my mouth when I nearly passed out in the doorway. My dad was also there, with my inhaler and I was alright but I never knew it was the banana that caused all of this until a few years later. I mean, I eat strawberries all the time, I used to eat bananas, there musta been something else in that shake. I never drank another smoothie again lol Fast forward to me at 24, I was slumber partying at my sis house, the next morning she gives me her half of a banana while she's making bacon and I took one bite and not even 30 minutes later my stomach started cramping like I've never felt. It was like it something was heated in my stomach and I started to get feverish all over again. Then my contacts started to get scratchy and so did my throat. It was much faster and way worse than the feeling the last time but I recognized it well cause I thought I was going to die. We jumped in my car and I had to pull over halfway to the hospital because I was starting to lose my sight because my eyes were swelling and messing with my contacts. She drove me the rest of the way. By the time we got to the hospital, I could barely walk or breath, my eyes were swollen, my mouth was swollen and it felt horrible. They saw me right away when I went in, I started throwing up in the trashcran. (Lol I remember the nurse saying "Yeah, that's banana") anyway, I spent about 3-4 hours in the hospital on a drip and then they let me go. I'm never going to eat a banana in my LIFE, not even banana bread or fake banana products. I check all my ingredients from now on.

Almost 31 years ago when I was pregnant I developed an intolerance to eggs, bananas and avocados. Thinking I would be fine after delivery with hormone shifts or whatever, but no. To this day I can't eat bananas, although I tolerate them in baked goods. I'm now vegan so eggs aren't a problem. Avocados, small amounts smashed are kinda okay but cubed aren't. I am guessing something with the process of digesting is to taxing on the system. Smoothies are a problem for sure, at home I just freeze mangos and do the best I can with smoothies. Seems everyone has some food issues, hubby can't do tomatoes or onions.

Only when I try to use one as a suppository.

10 · January 30, 2012 at 5:36 AM

Every day I would walk to work and eat a banana. After an hour of arriving, I would get severe stomach pains that grew worse and worse each day. I finally figured out it was raw bananas that were causing these pains after I was sent home from work.

When I ate "Fried Bananas" (which are actually plantains) and cooked bananas, I wouldn't get the same reaction. I also have to order smoothies without bananas (which is a real hassle). Every six months or so I can get away with half of a banana, but I don't try and push it.

Like your wife, I have no other Latex related allergies. Though I do not enjoy avocados, I love kiwis and consume them regularly. If there is any way to get ride of this "intolerance" or "allergy", I would love it, as bananas USED to be my favorite fruit!

For some reason I must have gotten a 'bad' bunch of bananas, don't know how thats possible. Sent me to the ER twice in one week with redness, itching, swelling in the face!

After that I waited a month and tried another bunch and no problem. hmmm, odd because one peels the banana!! (thinking pesticides)

if you are suffering from banana intolerance all of a sudden. or are becoming sensitive to many other foods., that is because your gut flora is different. Take http://www.renewlife.com/ultimate-flora-critical-care-50-billion.html and use food enzymes as well. your body stops producing those enzymes if you stop eating those food. How do i know this works??? because I was suuuuper sensitive to everything when i went paleo. I couldn't eat fruit, broccoli, potatoes, nuts, basically it became ridiculous. but now I m fine!! And btw, drink kombucha with your meals! Good luck everyone!!!

I am very latex sensitive and recently found out that due to my sensitivity is the reason that I cannot eat broccoli, bananas or avocados. I never would have imagined that eggs would also be on this list but I am currently experiencing the same symptoms that I have when eating the other wrongs. Guess I will now add eggs to my cannot eat list :(

Solution to the cramp: Every time you get a cramp after eating a banana, chew a pinch of Trachyspermum ammi (commonly known as ajowan or ajwain) and salt (1/3rd of ajwain in quantity), followed by a cup of water. It should help you digest the banana.

If that does not fix it up, drink a glass of water with a complete lemon squeezed into it (add some sugar and salt to taste). That removes the pain at least for me ( I use both remedies one after the other, just to be sure)

I've eaten bananas most of my life and loved them. 10 years ago at age 58 while vacationing in Puerto Rico I found myself getting very nauseous every morning shortly after eating a banana. The Puerto Rican bananas were shorter than I was used to back in Minnesota, but tasted about the same. I quit eating them in Puerto Rico and felt fine after that. When we got back home to Minnesota I started eating bananas again, but still got quite sick. I cannot eat bananas at all now. About once a year I would try just a bite of a banana and the result was the same. I can eat banana bread with no ill effects. Must be the heat in the baking that kills off whatever makes me sick. We went to the Mall of America this morning with our grandsons. We were in a Starbucks where my wife and I ordered a couple of Lattes and a banana/chocolate smoothie for the grandsons to split. They really didn’t like the smoothie so my wife and I each took a few sips. 20 minutes later I was violently ill. I’m not sure how this all started after 58 years, but it seems to be here to stay. No more bananas for me in this lifetime.

had two greenish raw bananas yesterday - mostly sleepless night and pretty gnarly stomach pain .. .it could be the cause.

I too developed gut pain from bananas as a teenager I'm now 33. Around 21 could no longer eat eggs and developed an allergy to latex. About a year later I could no longer eat avacados. I still cannot eat any of these foods. I tried a banana when I was pregnant 3 years ago did ok but tried another a week later and got the gut pain. I ordered some tacos for dinner this evening and they had guacamole on them so I am now in horrible pain writing this trying to figure out what I can do to relieve the pain.

0 · May 13, 2013 at 6:46 PM

I always ate bananas. always. with no trouble. ever. i ate them raw. in protein shakes, on cereal. etc. Then, all of a sudden, last week, I ate one before bed. I woke up in the morning with the most intense stomach ache, cramps, pain, whatever you want to call it. every 10 minutes for two hours, i would run to the toilet with the most intense pain, and i would sweat, get pale, feel nauseous and then I would think I was about to make an explosion...and only a little would come out. next day, had a banana again in the morning and same thing happened for an hour. but i still thought it was something else. i was fine over the weekend. and then boom, it happened this morning. I will never have a banana again. sorry for the TMI but this is so weird. I guess I should do see my dr. btw. for three days before i ate that banana at night.. i was on a very strict diet, had only a protein bar, a salad and a piece of chicken for dinner. maybe it had something to do with my 3 day crash diet. who knows.

A banana every couple of days used to be pretty standard for me. I started getting extremely sick and feeling cramping in my upper abdomen every once in a while and it took me a long time to figure out where it was coming from because I never felt sick from bananas before. I finally figured out the correlation and now I can't even have half of a banana in a smoothie without feeling extremely ill! I've heard that a small percentage of people who have problems with acid reflux have trouble eating bananas.

0 · May 09, 2013 at 3:31 AM

Ok let me say, that I ate bananas almost every day as a child. I'd have them in cereal, bananas on toast with warmed peanut butter (you'd have to have tried it) I would eat a few bananans a week. Then one day, I was 16 (I am 33 now and Pregnant) and had to pull over and throw up. Fast forward to 21 years old. I had a banana and 2 cups of Orange Juice. At that time, I also had Weight Loss Surgery. So about an hour later, I had violent cramping, diahreeah, thrown up several times. This episode lasted about half hour. I was in AZ and thought it was something else I had eaten...Fast Forward a few weeks later. Same thing happened with half of a banana. I thought it was mental. I figured out it was bananas. At 27, I thought I was over it, my friend made banana pudding with the vanilla wafers. I just HADDDDDDDDDDDD to have some. I had a slice, about the size of a quarter. I had stomach cramping for 2 days!!!!

Now I am 33, and I am craving bananas because I am pregnant (15 weeks). I broke down and bought 2 yesterday, kind of black and as I googled this, I am eating half of a banana. I burped a few times. nothing big. I will see. Hopefully because it is a little black and I am eating it slow, I hope this makes a difference.

I am NOT allergic to any other fruit that I know of. Sometimes pineapples make my mouth a little raw but I eat them with no problem. I don't hardly eat mango. I do not have a problem with Kiwi. I have anaphalytic shock with brazil nuts but with bananas, there is NO ITCHING, SWELLING OR SKIN REACTIONS. Just DIgestive. My Brother says that when you get older your body cannot digest things sometimes and you develop a reaction that only gets worse.

My sister cannot tolerate tomatoes, coffee, or Dairy once she turned 40. My mother who is 69 has a new allergy to Soy yet Soy products are in everything. Her blood test came back positive for Soy though.

I have no idea why this happens and I am curious as well. I am happy that I am not alone though! It's been about 30 minutes now and no adverse reaction to the banana I just had. Maybe this baby is helping me digest it. I don't know but I will come back to report if anything has changed

Before paleo I could not eat bananas alone. The smallest bite made me puke. It took 6 months of paleo to tolerate them again

I am 29 and in the last couple years I developed an allergy to bananas, avocado, and eggs just like another commenter mentioned. It really sucks because all three were a major part of my diet. I wish someone knew what caused this. Is there any sort of explanation?

0 · February 26, 2013 at 12:53 AM

I have a latex/banana allergy and it started out like that. For the longest time I would have gut reactions when I ate bananas and no other reactions, then I developed a stronger latex allergy (can not touch latex without getting hives), now I can not eat bananas at all without my throat getting scratchy and closing up. I can also not eat honeydew melon or cantaloupe anymore without a reaction. So in my experience, food intolerance can get worse the more you aggravate them. to date, no reaction to avocado, kiwi or nuts but I can not eat most foods that grow in South America for some reason.

190 · February 24, 2013 at 6:07 PM

Bananas are a frankenfruit, they have basically been bred into sterile, seedless clones of the same banana and thus have lost their protection against fungus and such, from what I understand

0 · February 11, 2013 at 11:43 PM

I suddenly developed intolerance to eggs and advocadoes after my pregnancy, I did try the organic thinking it may be something chickens were fed or pesticides, and that did not make a difference. For pain it's a heating pad on my stomache and one on my back, ginger and/or peppermint, fennel, dill tea, and lay absolutely still until the pain goes away Then usually about 3 days of very easily digestable bland diet, as I found out that if I try to eat a normal diet right after an attack, any food (not bland or very easily digestable) can set it off again.

0 · January 08, 2013 at 4:57 AM

wow, never thought I would find so many people with the same problem as me. I used to have sweats, paleness, extreme cramping, gas, bloat, even vomiting sometimes, chills. finally discovered the cause was bananas... only raw ones. dried, cooked etc, NO PROBLEM. This is definitely an intolerance and not an allergy (no breathing/ itching issues) but I have always wondered what exactly gets lost when a banana is dried or cooked that I'm intolerant to, I would love to know to avoid other foods that might have them as well, although, so far, only bananas are problematic and I eat pretty much anything and everything and have been for almost 33 years.... at least I know I'm not alone, just wish I knew what part exactly I'm intolerant to.

0 · November 30, 2012 at 4:37 AM

After eating bananas, occasionally, for the first 50 years of my life, I suddenly developed a severe intolerance- in about 1/2 an hour, it started with numbness in my extremities, advancing to my core, I became extremely weak and dizzy and could barely crawl to bed; 12 hours later, I was "fine"! My doctor blamed it on a flu-bug. Ok, sounds reasonable. About two weeks later, I just happened to eat another banana, without even thinking about it. The same reaction, only faster - about 20 minutes and it was 24 hours before I even began to "feel normal"- -doc had no explanation except "possible allergic reaction"!! Duh - -no kidding, really? To this day, I do not eat raw bananas; I can eat them in "cooked form" like banana bread, or muffins, fried banana with something else - -no reaction! So, all you banana lovers, just eat them "cooked", in or with something else.

0 · November 29, 2012 at 9:45 PM

I have been doubled over in pain for the past 24 hours since i had eaten ONE Banana yesterday at lunch. Stomach feels like it is being cut open from the inside and the pain comes and goes. Going to try some "beano" after work. i've heard that this can help alot with this situation. But once this stops i'll tell ya i will not be eating Bananas again. . . :-( Any other remedies anyone can think of?

Bananas give me unbearable heart burn.I don't bother asking why I just don't eat them.

4176 · July 11, 2012 at 6:08 PM

Bananas are the only fruit I eat, I eat them every day and have stomach problems, I will cut them out and see what happens!

0 · July 11, 2012 at 5:48 PM

I've encountered the same problem. I have no allergies (I've been tested) but found that after eating one to two bananas daily for a period of time, I started cramping/feeling nauseous to the point where I've stopped eating bananas (even in smoothies).

I've read that, if you consume too many bananas, it is possible for your body to react to to something in the banana as your immune system begins to recognize it as an foreign invader.

0 · May 06, 2012 at 3:17 AM

About a year ago I started becoming very ill after eating bananas. I suffered severe chest pains that radiated up into my face and had trouble breathing. I actually thought I might be having a heart attack but quickly took an antacid and drank some milk which calmed my symptoms. For dinner tonight I had a veggie wrap that contained avocado and I experienced the exact same symptoms. That is why I am now on this site. This can be scary stuff. I haven't had bananas since I figured out it was causing these symptoms and now no more avocado! Thanks to all for sharing this info.

1560 · May 03, 2012 at 9:10 PM

My body has zero tolerance of bananas now.About 30 mins after I eat one,I'm irritable and light headed.Not the fructose,because other fruit doesn't have the same effect.

Was she eating 34 bananas a day?

3926 · August 09, 2011 at 1:34 AM

Did she eliminate bananas for a period? For me, not with bananas, but I did notice that I was "fine" on dairy until going Paleo for a few months. Added dairy back in and watch out below! I think that sometimes we believe we are fine with something until our gut heals. Then the truth comes out.
