Diseases of the Stomach
When there is disruption of the normal balance of the corrosive effect
of gastric juice and the protective mucus on the stomach lining it results in
ulcer formation. This can be caused by stress, excessive cigarette smoking and
ingestion of some drugs.
Diseases of the liver
Virus infections are the commonest causes of acute liver injury. It
includes Type A, Type B and Type C. Type A virus spread through food, water and
contaminated faeces. Type B & C viruses spread by blood and blood products,
body fluids such as saliva, semen, vaginal secretions and from mother to fetus.
Type B virus causes massive liver necrosis and death. Intravenous drug addicts
and male homosexuals are at a greater risk.
This is inflammation of liver due to alcohol
abuse, hepatitis B & C virus infections etc. The liver tissue that is
destroyed is replaced by fibrous tissue, leading to liver failure.
This is not a disease but a symptom of liver disorder. It is due to
abnormal bilirubin metabolism and excretion. There is an obstruction in the
flow of bile from the liver to the duodenum, resulting in bilirubin
accumulation giving rise to the yellow colouration of skin and conjunctiva.
