The Celiac Society of Australia has asked men to get themselves checked if they feel down constantly.
Chairman of the Clinical Advisory Committee of the Celiac Research Fund Dr Jason Tye-Din said that there was an increasing incidence of the disease in men, which was a cause for concern.
"Celiac disease causes inflammation of the bowel, which in turn makes it hard for people to absorb nutrients from the food they eat. As a result, one of the first signs can be unexplained tiredness and a general lack of energy or get-up-and-go," he said. "Many men put it down to the fact they're leading a busy lifestyle or just getting older - but this type of tiredness is not normal."
Celiac disease is triggered by gluten; a protein found in wheat, rye, barley and oats and is estimated to affect 1 in 100 people in Australia. Experts say 75% of them are unaware of the disease condition.
