Could I Have Gluten Sensitivity?

Here are a few symptoms I have pretty much all of the time:

*Fatigue - especially after eating
*Joint pain - all of the time
*Abdominal discomfort - pain sometimes, discomfort most of the time
*Bowel Movements - won't have one for up to three days and the loose or diarrhea.
*B12 deficiency / Iron deficient anemia
*Extreme weight gain
*Eczema
*Sinus infections

I have been diagnosed by my doctor with the following:

*Complications, routine after having gallbladder removed

*Rheumatic Fever (joint pain after a strep infection was the reason for this dx), this dx was noted as incorrect after consulting with a specialist.

*Sinus infections are common in people with allergies.

*Anemia is common in women who have children, especially after having twins.

*Eczema is common in people with allergies.


I understand the reasoning behind each of the diagnosis' listed, but I am so fed up with no real help.

Could the reason for all of these be a gluten intolerance or allergy? I know I have four children and a semi busy life, but I have made it a point to get at least 8hrs of sleep per night, have been exercising and watching my diet to lose weight (the right way, no crash diets) and still I am so tired, I often have to take a nap (1-2 hrs) in the afternoon with my youngest child.

I lost my job about a month ago. I thought it might help with my symptoms of fatigue as it was a high stress position, but it is honestly the same.
Please help!

Thanks,
