Dizziness after eating green beans?

[EndlessSummer]

I only notice recently every time I eat green beans the roof of my mouth gets slightly itchy and I get extreme dizziness.  
 

I get shaky and sweaty and it last for an hour or two before it goes away. I’ve been allergy tested in the past for food allergens only two came back positive (both in the tree-nut family) nothing in the legumes.  

(I do have a celiac disease diagnosis, the reason I was food allergy tested was because I ate a walnut and my lips swelled up) 

I decided to test this out to be sure so I ate a couple of cooked green beans last night within 15 minutes I was spinning, my shirt drenched in sweat. My heart racing.
 

I’m not sure what this is, I do have issues with others vegetables  as my stomach doesn’t seem to tolerate them. Even when they’re cooked I just can’t digest them but they never made me as dizzy and sweaty as the green beans. 
 

anyone else experience this?

Welcome to celiac.com, @EndlessSummer! Do you react to all vegetables or just specific kinds or families of them? What you describe with green beans sounds like it has an anaphylaxis component. Like you, walnuts are a problem for me. They will often give me a scratchy throat so I try to avoid them. Does it matter if the vegies are raw or will-cooked in how you react to them?

@EndlessSummer,

You said you had an allergy to trees.  People with Birch Allergy can react to green beans (in the legume family) and other vegetables, as well as some fruits.  Look into Oral Allergy Syndrome which can occur at a higher rate in Celiac Disease.  

Switching to a low histamine diet for a while can give your body time to rid itself of the extra histamine the body makes with Celiac disease and histamine consumed in the diet.  

Vitamin C and the eight B vitamins are needed to help the body clear histamine.  

Have you been checked for nutritional deficiencies?

As already mentioned here, and based on your description, this sounds like a serious and specific reaction to green beans. While your prior allergy tests didn't flag legumes, it's possible to develop a new allergy at any time. The symptoms you describe—extreme dizziness, racing heart, sweating, and itching—are consistent with a systemic allergic response, not just an intolerance. Given your history of celiac disease and tree nut allergies, your immune system is already predisposed to sensitivities. It is crucial to stop consuming green beans immediately and consult an allergist. They can perform more specific testing and may prescribe an epinephrine auto-injector for emergency use, as this type of reaction can be unpredictable and potentially escalate.

I use to see a dietician years ago and she recommend I cook my  vegetables which worked for a while.  The reason I can’t eat other vegetables is because it messes with my stomach. This is the first time I’ve gotten dizzy and sweaty upon eating veggies though. The only vegetable that I’m able to tolerate so far are cucumbers.  I have been in the process of eliminating food over the past few years that I don’t seem to tolerate. Going to add this to the list unfortunately. Thanks for the reply.

Thank you. I do have an epi pen I’ve been renewing for a few years now since tree nut allergy diagnosis. I haven’t seen allergist in some years.  It’s so bizarre as the list of food I’m able to tolerate seems to get smaller and smaller. But I’ll look into making an appointment with my allergist. Thanks again.

 No I haven’t been checked for the nutritional deficiency. My family has commented that I look like I may be lacking some kind of vitamin. Because of the pink circles under my eyes and just general tiredness and weakness I feel all the time. Thanks for the reply!

@EndlessSummer,

You would do well to get checked for anemia.  I had those dark circles under my eyes when I was anemic.  Fatigue and muscle weakness are early symptoms of nutritional deficiencies, especially in the eight B vitamins, and essential minerals like iron and magnesium.  

The malabsorption of essential nutrients goes along with Celiac disease and needs to be addressed.  Doctors tend to overlook the importance of vitamins and minerals.  Get more than just B12 and Vitamin D checked.  It's rare to have a deficiency in just one vitamin or mineral.  The Celiac disease, the absorption of all the nutrients are affected.  The eight essential B vitamins all work together.  All eight are needed to correct deficiencies.  A multivitamin is not sufficient to prevent nor correct nutritional deficiencies.  Talk to your doctor and dietician about supplementing with a B Complex and other nutrients while you are trying to heal.  

B vitamins are needed to make digestive enzymes so we can digest our food better.  Food has to be digested in order for the vitamins and minerals to be released and then absorbed.  This can be a slippery slope.  Supplementing with B Complex vitamins can help.

B vitamins and Vitamin C help reduce inflammation and clear histamine.  Histamine is released during the immune response to foods to which we're sensitive.  Mast cells that make and release histamine can become over stimulated and release histamine at the slightest provocation.  Thiamine B1 helps the mast cells to NOT release histamine.  Ask your doctor and dietician about Mast Cell Activation syndrome.

I found following a low histamine paleo diet very helpful.  I followed the Autoimmune Protocol diet developed by Dr. Sarah Ballantyne (a Celiac person herself) most beneficial.   The AIP diet removes lots of foods that are potentially irritating so that your body can heal.  Benfotiamine a form of Thiamine B1 helps the digestive tract heal.  Tryptophan, lysine and theanine (all essential amino acids) help us heal, too.  

Many new Celiacs also have SIBO which can cause ongoing digestive problems and contribute to Mast Cell Activation syndrome.  The SIBO bacteria feed off the excess carbohydrates we aren't digesting.  The AIP diet cuts out carbs, which in turn starves out the SIBO bacteria, allowing more beneficial bacteria to repopulate the digestive tract.  

I had vast improvement within a few weeks following the AIP diet.  I had gotten down to being able to eat two foods before finding the AIP diet.  It really does work.  It's like feeding a colicky baby easy to digest foods giving the body time and vitamins needed to heal.

I do hope you will discuss these with your doctor and dietician.  

Do take care and let us know how you are progressing!  Best wishes!
