Symptoms of celiac disease vary widely and may come and go. They may be very mild and go completely unnoticed, or
they may be severe and impact daily life.
Gas, abdominal swelling, and bloating. These
symptoms result from a failure of the
small intestine to absorb nutrients from food. You may also have mild stomach
pain, but it usually isn't severe.
Abnormal stools. Diarrhea or bulky, loose (or
watery), pale, frothy, and foul-smelling stools often occur. The stools may
contain a large amount of fat and may stick to the sides of the toilet bowl,
making them hard to flush. Children and adults often have the
same types of symptoms. But intestinal problems, such as constipation, are more
likely to occur in children.
Weight loss. Adults and children may have
unexplained weight loss despite having a normal appetite. Younger children may
fail to gain weight and grow as expected. This is called
failure to thrive.
Fatigue and weakness. Celiac disease can cause
a general lack of energy and strength. Sometimes poor nutrient absorption
causes fatigue and weakness.
Vomiting. Some people may get sick after eating
gluten. Children are more likely than adults to have this reaction.
If not treated, celiac disease can lead to other problems. You may have problems with memory and concentration. Children may be more irritable. Adults may show signs of depression.
