Most of the time dry lips are just that -- lips that have lost moisture because of dehydration, too much wind or too much sun. Occasionally, however, dry lips may signal a more serious condition. When a health problem exists, dry or cracked lips could be one of many symptoms.
For example, if dry lips are accompanied by a fever, red eyes and tongue, swollen lymph nodes, and swollen, red skin on your hands and feet, they could be an early symptom of Kawasaki disease [source: Mayo Clinic]. This disease is most common in young children between the ages of 2 and 5, but doctors aren't quite sure what causes it. Even though children typically see a full recovery, heart problems can result.
Dry, cracked lips have also been associated with a deficiency of certain B vitamins. For example, although it is not a typical symptom, cracked lips (especially at the corners) can sometimes signal a folic acid deficiency [source: WebMD]. They also can be a symptom of a riboflavin (vitamin B2) deficiency. Those at risk for this condition include people who are elderly or have a chronic illness or alcohol dependence. A riboflavin deficiency can typically be remedied with a balanced, healthy diet or a vitamin supplement [source: Mayo Clinic].
