The symptoms of celiac disease vary greatly from one person to another, making diagnosis difficult. Infants and children often have diarrhea, abdominal distention and symptoms of malnutrition such as short stature, anemia (weakness or low stamina), defects in teething, failure to thrive, or developmental delay.
In adults, digestive complaints are common including: abdominal pain, bloating, gas and diarrhea. Weight loss is most common, but symptoms of weight gain and constipation are not unheard of. Only some individuals with celiac disease suffer typical digestive symptoms, while others may display no visible symptoms at all.
Further symptoms vary and can include mouth ulcers, extreme fatigue, depression, bone pain and others. A serious skin condition (called dermatitis herpetiformis) that results in an itchy rash with bumps and blisters is sometimes a result of celiac disease.
Other conditions associated with celiac disease include osteoporosis, depression, infertility, type 1 diabetes, thyroiditis, arthritis and neuropathy. If celiac disease is diagnosed early and treated, the damaged tissues can heal and the risk of developing many of the long term complications of this disease can be reduced.
