List Of Diseases

Humanity has experienced throughout the history many kinds of deadly diseases that have shaken up the medical systems. Scientists had tried to develop theories in order to find treatments to prevent the appearance and if possible to cure some of the deadliest illnesses that affected millions of human beings. Diseases like cancer, AIDS or cardiovascular problems cause the death of hundreds of people every year worldwide. The top four dangerous diseases are described below:

Heart disease affects heart muscles and is considered to be the primary cause of death among adults. It includes symptoms such as irregular and rapid heartbeats, exhaustion, chest pains, difficulties when breathing or dizziness. The causes may vary from smoking, inappropriate foods, diabetes, lack of exercises to heredity. Medicines help affected people get better by improving the heart condition but they cannot restore the health. A proper treatment and a healthy lifestyle may help patients live with the disease for many years.

Cancer is the second cause of death among people. In all its forms, it has killed hundreds of people yearly. Cancer affects many parts of the human body. The most common forms are breast cancer, skin and colon cancer. Leukaemia, known as blood cancer is described as abnormal multiplication of white blood cells. When treating it, it's important for doctors to know the patient's medical history. The procedures are complicated and often hurtful ranging from surgery, radiotherapy, chemotherapy to immunotherapy.

AIDS also known as Acquired Immune Deficiency Syndrome is the advanced form of HIV (Human Immunodeficiency Virus). This virus attacks the immune white cells also called CD4, which act in order to protect the human body from illnesses. When the immune system looses too many Cd4 cells, the human body gets very week and can't fight against infections which finally kill the patient.

People with HIV can live many years without knowing it but HIV can develop AIDS if no proper treatment is administrated. Death occurs when a deadly infection installs in the weakened body which can no longer survive.

Diabetes is also a well known chronic disease which affects thousands of people around the world. It causes heart strokes, kidney diseases, infections due to high blood glucose which attacks blood vessels. There are three forms of diabetes: type 1 is the insulin dependent diabetes affecting mostly teenagers and children. Treatment implies taking insulin, lots of exercises and strict diets. Type 2 affects people of all ages. This type of diabetes makes pancreas not to secrete the needed insulin. Overweight people are likely to develop this kind of diabetes. The third type is the gestational diabetes which appears at pregnancy.

Diseases such typhus, cholera or malaria have horrified the humanity throughout old times by killing millions of people. Scientists take enormous efforts to discover treatments for which are now incurable diseases. Dealing with an illness it's not all about the treatment. Prevention is the key. Yet, maybe the worse of all is denial and indifference regarding our body.
