can allergies cause stomach problems?

Long-term use of PPI's like Prilosec can cause nutritional deficiencies and small-bowel bacterial overgrowth. It is best to be taking a comprehensive multi-vitamin/mineral supplement and probiotics if you take a PPI.

Hi everyone. First time poster.

This is related to a dull stomach ache that affected me for approximately 3-4 months about 4 years ago. To cut a long story short, I had all the tests done (blood tests, barium, gastro-endoscopy, colonoscopy, breath test, etc,.) and they found NOTHING. The final diagnosis was STRESS. With great pain and much frustration I had to accept this diagnosis. Each year on almost precisely the same date, the stomach ache returns, and last Saturday was no expection (almost exactly to the day as last year and the year before that). My initial thought was panic, then depression. I'm not sure I can go through another bout of this dull, energy-sapping constant ache day in, day out.

However - my question to anyone who can please help is this. At the same time each year my pollen allergies begin, and I only noticed this connection this time. about 2 months ago my allergies began again and at the moment the usual runny nose and itchy eyes are in full effect. Since then they have got better and I've stopped taking anti-histamines. Is there ANY CHANCE that my allergies could be causing my stomach ache??

I just returned from my allergy Doctor and he said it was very unlikely, but he was in a rotten mood and didn't feel like saying much at all.

Is there someone, anyone out there who can help.

Thank you soo much for reading.

HI, First time poster. I began having sudden terrible stomach aches and nausea two years ago August. It felt like food poisoning. If I had just eaten I would vomit. But it also came without warning when I hadn't eaten for hours. Many tests later the doctors, who all agreed it must be gastric, could find nothing wrong. The problems gradually declined over the winter but returned the following September, and were much worse. It occurred to me to see my allergist/immunologist after realizing the first trouble began when I was weaning myself off GABApenton which he had diagnosed previously for recurring vertigo. Once the vertigo was cleared up I had gone off the medication. After hearing what was wrong, He said the two were related and that I had Chronic Oelvic Pain Syndrome which can have various causes. Since I had already had a Oelvic exam and ultra sound, CT scan, colonoscopy, blood tests, etc. and that the problems began as I was coming off the GABApentin, the most likely cause was an allergic type of reaction to something airborn. GABApentin represses the production of various enzymes, one of which reacts to the ingestion of parasites. When the parasite is sensed, the enzyme causes histamine and prostaglandin to be release into the stomach walls. The resulting inflammation and cramping are the body's attempt to dislodge the parasite, which of course in my case hadn't actually been ingested at all. I was just reacting to something blooming out in the woods. He put me back on the medication which successfully stopped the stomach attacks but caused depression. We then tried Baclafin which stopped the stomach attacks but caused headaches. The solution has been a low dose of GABApentin (300 mg twice a day) plus a prescription dose of Prilosec twice a day and a supplement called GABA ( not the prescription drug). I have been able to go off the GABApentin for extended periods but have just gone back on following major attack just yesterday, July 30. Whatever it is, it's blooming early this year. As a child, I suffered from many allergies and took shots for years. This past year, with the stomach troubles my doctor tested me for the most likely airborn allergens but was not able to determine exactly what it is out there that causes this. Still, I am better and the problem seems to be controllable. For anyone experiencing this sort of issue, I wish you the best and hope that the medications I have mentioned here will work for you. GABApentin, by the way also stops the post nasal drip problem, or did at least for me.

Yes, allergies cause stomach and belly pain. I moved to Florida from north, developed allergies and asthma within 2 -3 years and bad stomach aches. My advise is move back if you can. Florida is not for everybody!
