The discomfort can extend to the lower back or legs. Menstrual cramps are not the same as the symptoms experienced due to premenstrual syndrome (PMS), although the symptoms of both disorders can sometimes be experienced together. Many women suffer from both PMS and menstrual cramps.
Some diseases which involve other parts of the GI tract can manifest in the mouth, alone or in combination, including: 1  Gastroesophageal reflux disease can cause acid erosion of the teeth and halitosis. 2  Gardner's syndrome can be associated with failure of tooth eruption, supernumerary teeth, and dentigerous cysts.
Each part of the GI tract â esophagus, stomach, small intestine, and large intestine â has a unique function to perform in digestion, and each has a distinct type of motility and sensation. When motility or sensations are not appropriate for performing this function, symptoms occur. Gastrointestinal (GI) motility is defined by the movements of the digestive system, and the transit of the contents within it. When nerves or muscles in any portion of the digestive tract do not function with their normal strength and coordination, a person develops symptoms related to motility problems.
