                          1.  Mouth Disorders

                       a.  Parotid  or  mumps  is  an  infectious
                           disease caused by a viral infection. The
                          infection  usually  attacks  the  parotid
                           gland  (a  gland  that  produces  saliva),

                           causing swelling. A common symptom
                          when a person has mumps is swelling
                           of the cheeks and jaw.

                          little saliva. Xerostomia can be caused
                           by  certain  drugs,  being  nervous,  and   Figure 18. Mouth Disorders (a) Paratoid and (b)

                          not drinking enough water.


                       2.  Stomach Disorders


                          a.  Gastritis  is  an  acute  inflammation  of  the  stomach  lining  due  to
                             contaminated food.
                          b.  Maag  is  a  disorder  characterized  by  discomfort  in  the  stomach,  which  is
                             generally  mild  and  appears  when  consuming  certain  foods  or  drinks  and
                             when eating too late. Maag can be overcome by improving your diet and
                             avoiding the things that trigger them.
                          c.  GERD (Gastroesophageal  Reflux Disease)  is  a disease characterized  by
                             the  rise  of  acid  from  the  stomach  into  the  esophagus  (esophagus).
                             Indigestion is caused by loose or not correctly closing the valve between the
                             esophagus and stomach.
