Women are more likely to develop food allergies in adulthood than men and to grapple with severe food-related anxiety.

When any of these symptoms occurs regularly, heartburn should be considered as a potential cause.

People should consider seeing a doctor if lifestyle changes don't reduce the number of times they urinate each day.
