Up-front, I cannot express my gratitude sufficiently. Thank you so much for all you highly valuable and much appreciated support 🙏🏻

Please can you advise what tests I should have for a diagnosis on mast cell activation syndrome (mcas) and/or histamine intolerance and h.pilori? Are histamine intolerance and mcas thr same thing?

Kind regards, 

Bronwyn

Histamine intolerance and MCAS go hand in hand. If you have histamine intolerance, you will have MCAS and vice versa. I'm not saying they are exactly the same thing but I'm saying you really can't separate the two. Another way putting it is that MCAS is the root cause of histamine intolerance. If you want information on diagnosing MCAS just google it. Or, you might try going on a low histamine diet to see if your symptoms improve. I don't think there is a cure for MCAS but a slow histamine diet can help manage it. To some degree, antihistamine therapy (zyrtec, allegra) helps control the symptoms but you may still have outbreaks at times. There are many things that contribute to histamine levels in the body including environmental and seasonal allergies. It's not just what you eat but that is the one thing you can exercise some control over.

@Bronwyn W,

I don't believe a diagnosis is necessary for histamine intolerance.  

Our bodies can make histamine.  Mast cells (a type of immune cell) release histamine in our bodies in reaction to perceived invaders like bacteria, viruses, and gluten. 

Our food contains histamine.  Some foods contain higher levels of histamine than others.  High histamine foods include fermented foods, citrus fruits, crustaceans, and more.

Our bodies can breakdown histamine.  Trouble arises when our bodies and our foods have levels of histamine that our bodies cannot clear fast enough and "our cup runneth over."

Our bodies need certain essential vitamins to breakdown histamine.  Vitamins like Vitamin C, and Cobalamine B12.  Vitamin D helps with immunoregulation.

Thiamine Vitamin B 1 helps Mast Cells to hold their wad and not release histamine.  Mast cells will degranulate and release excessive histamine when there is thiamine deficiency.  

These are all vitamins that are frequently low or deficient in newly diagnosed Celiacs.  Checking for nutritional deficiencies is part of proper follow up care for Celiac patients.  Celiacs are often low in essential vitamins and minerals across the board because of the damage done to the small intestine where nutrients are absorbed.  

Try the Autoimmune Protocol Diet and choose low histamine foods.  Supplement with the eight essential B vitamins, magnesium glycinate, Vitamin D, Vitamin C, and zinc.  

I followed the Low Histamine AIP diet and supplemented with extra Thiamine in addition to the nutrients listed above.  The extra Thiamine really helped with mast cell degranulation.  My reactions to high histamine foods became less quite quickly.

The book The Paleo Approach  by Dr. Sarah Ballantyne was extremely helpful.  She is a Celiac herself and designed the diet for herself and her family.  This diet has been scientifically shown to reduce inflammation and promote healing in the digestive tract.

For H. Pylori infection you will need to be tested by a doctor.

 Hope this helps!

      So I've been dealing with chasing the name celiac because of my body actively dealing with health issues related to celiac though not eating. Diagnosed in 1994 before foods eliminated from diet. After 25 years with former pcp I googled celiac specialist and she wasn't because of what ive been through. I wanted my results to be sent to my pcp but nothing was sent.I have email copies.I did one zoom call with np with team member from celiac specialist in Nov 2025 and she asked me why I wanted to know why I wanted the celiac diagnosis so bad, I sad I don't, its my life and I need revalidaion because its affecting me.KB stated well it shows you are.I asked then why am I going through all this.I was labeled unruly. Its been a celiac circus and medical has caused anxiety and depression no fault to my own other than being born with bad genetics. How is it legal for medical professionals to gaslight patients that are with an ailment coming for help to be downplayed? KB put in my records that she personally spent 120min with me and I think the zoom call was discussing celiac 80 min ONE ZOOM call.SHE is responsible for not explaining to my pcp about celiac disease am I right?

      What is the best liquid multivitamin for celiac disease?

      I've noticed with my age and menopause my smell for bread gives me severe migraines and I know this.Its alarming that there are all these fabulous bakeries, sandwich places pizza places popping up in confined areas.Just the other day I suffered a migraine after I got done with my mri when a guy with a brown paper bag walk in front of me and I smelled that fresh dough bread with tuna, I got a migraine when we got home.I hate im that sensitive. Its alarming these places are popping up in airports as well.I just saw on the news that the airport ( can't remember which  one)was going to have a fabulous smelling bakery. Not for sensitive celiacs, this can alter their health during their travel which isn't safe. More awareness really NEEDS to be promoted, so much more than just a food consumption!FYI I did write to Stanislaus to let them know my thoughts on the medical field not knowing much about celiac and how it affects one.I also did message my gi the 3 specialist names that was given on previous post on questions on celiac. I pray its not on deaf door.
