I'm on my 10th stomach virus this year and have had every gi test imaginable done with clear results. my only other symptoms are headaches and low wbcs (2.8 to 4). where do i go now?

Persistent GI prob: Sometimes it is hard to find an answer. Assuming your GI eval did everything, including endoscopy and test for Gluten entropathy, your doctor may consider other causes like CNS issues, like abdominal migraines and abdominal seizures and have you seen by a neurologist. Other thought is to consider environmental toxins like carbon monoxide, etc.

It may not be GI: It may not be GI related. If you're having headaches associated with vomiting, especially if your headaches awaken you at night and if your vomiting is worse first thing in the morning. If this is the case you may need neuroimaging (CT or MRI) of your brain. A low WBC count is non-specific and could suggest something viral, but a virus is unlikely this many times.

Celiac Diseae: Althouch Low WBC is not a typical of this problem, it is a disease which can cause recurrent GI symptoms associated with headaches. Lupus may be another which may qualify. One would need other test results to pin down a more exact result. For instance thyroid studies, the rest of the CBC, Liver Function Test results, the size of the spleen? Infections such as Ehrlichiosis in tick endemic areas

Diet: What is your diet like? I would probably begin there. I like the book, "Dr. A's Habits of Health" by Dr. Wayne Scott Anderson. Start by eliminating processed foods. Shop on the perimeter of your grocery where all the fresh foods are and avoid the central aisles. Begin eating 5-6 smaller meals each day and drinking plenty of water. If you drink soda try to stop and decrease your caffeine.
