It seems that many people feel that the most common symptom of celiac disease is the onset of diarrhea.
The fact is that most people with this disease don't have any gastrointestinal symptoms at all.
If they do have gastrointestinal symptoms, then it is often problems with constipation, reflux, gas, or bloating.
Celiac disease suffers can have hundreds of symptoms.
Some of the more classic symptoms of this disease are:

• Abdominal Pain
• Acid Reflux
• Bloating
• Constipation
• Diarrhea
• Gas
• Nausea
• Vomiting
• Weight loss or gain
• IBS

You may be surprised, though, to find some of the more common symptoms are not gastrointestinal in nature at all.
People are more apt to have what is called extra intestinal (outside the intestine) symptoms.
This is just a small list of the symptoms:

• Weakness and fatigue brought on by iron deficiency
• Vitamin deficiencies
• Headaches
• Joint Pain
• Depression
• Inability to concentrate
• Infertility
• Menstrual cycles not normal
• Pre mature menopause
• Seizures
• Respiratory problems
• Eczema
• Acne
• Hair loss
• Bruising easy
• Low Blood Sugar
• Anxiety
• Fibromyalgia
• Arthritis
• Osteoporosis
• Prediabetes
• Ulcers
• Dermatitis
• Neurological
• Fuzzy Brained

One of the worst things though is that Celiac Disease can go for years being misdiagnosed.
Even having the IGE-SERUM, TTG AB-IGA, TTG AB-IGG, GLIADIN AB IGA, and GLIADIN AB IGG blood test showing negative is not a sure thing.
Try going on a gluten-free diet for a couple of weeks and see if that makes a difference.
Some people feel a change in as little as 12 hours! Also you can go to Google and search for celiac disease + forum and find a lot of great tips and support for celiac disease suffers.
Don't put it off though because this disease can be dangerous if not handled properly.
Here's to wishing you the best of health and happiness.
