Having very pale lips could show that you have an iron deficiency or that your thyroid gland doesn't work properly. They can also suggest some heart conditions or lung problems.

Cracked lips that are not due to seasonal changes could show diabetes as the high level of glucose could encourage candida (a yeast infection).

Finally, if you get bleeding gums, it is often a build up of plaque due to bad oral hygiene. You need to brush twice a day and remember to floss to avoid this.
