I'm looking for the definition for medical diagnosis's?

Gastroenteritis , Alcoholism, Thrombocytopenia. what is this? caused from?

Eosinophilic gastroenteritis is a rare digestive disease characterized by the presence of a particular type of white blood cell (eosinophils) in one or more of the three layers that make up the lining of the gastrointestinal (GI) tract. This includes the stomach, small intestines, and large intestines.

Alcoholism: Physical dependence on alcohol to the extent that stopping alcohol use will bring on withdrawal symptoms. In popular and therapeutic parlance, the term may also be used to refer to ingrained drinking habits that cause health or social problems. Treatment requires first ending the physical dependence, then making lifestyle changes that help the individual avoid relapse. In some cases, medication or hospitalization are needed. Alcohol dependence can have many serious effects on the brain, liver, and other organs of the body.

Essential thrombocytopenia is a rare blood disease characterized by reduced levels of platelets in the circulating blood. Platelets are essential to the complicated process known as blood clotting and, if they are in short supply, bleeding may occur that can become life-threatening. The platelets are produced in the bone marrow and may be in reduced supply because of (1) impaired or reduced platelet production in the marrow, (2) increased destruction of platelets faster than they can be replaced by the marrow, or (3) the presence of one of several genetic disorders. There are also false thrombocytopenias. Major symptoms include a tendency to bleed excessively into the skin or mucous membranes, especially during menstruation, nosebleeds and bleeding gums.

Hope this helps.
