The Diversity of Diseases
A disease is an abnormal condition which negatively effects the function or structure of part or all of an organisms, and this is not because of any direct external injury. Most diseases are frequently referred to as medical conditions which are typically associated with certain characteristic signs and symptoms. These signs can vary depending on the type of disease, as well as its physiological features. Some of these symptoms include:
Most diseases are generally categorized as either infections or disorders. These classification systems have also been used to explain how diseases affect the body. The word “disease” actually means a collection of things which cause or result in death. Thus, in order for us to define or specify a certain disease, we need to know what kind of organisms it affects or causes, as well as the characteristics of the diseases themselves.
Infections, like the flu, are typically characterized by general weakness, fatigue, headache, and fever. Other common infections include AIDS and SARS. On the other hand, disorders include arthritis, celiac disease, diabetes, asthma, cancer, heart disease, kidney disease, parasites, and vitamin D intoxication. Meanwhile, many disorders such as those mentioned above also can be developed when the person is stressed or exposed to a specific substance. Cancer is one of the few exceptions.
It has also been established that diseases affect the body through their physiological or biochemical processes. This is why, for example, cancer is considered as a disease which develops through an abnormal growth of cells. Another example would be HIV, the Human Immunodeficiency Virus. HIV affects the immune system, the part of the body which fights against diseases. In this manner, it is evident that diseases have their own underlying causes.
There are a number of diseases that can affect a human being. Some of these diseases are terminal. These include cancer and AIDS. The others are not terminal, but they can be very debilitating and life-threatening. For instance, common colds can be crippling, as can minor diseases such as the common cold and the flu.
While diseases can affect everyone, prevention is still better. People need to make sure that they take their medications on time and eat healthy foods. They should also exercise regularly and get enough sleep. Overall, prevention is still best than cure.
Of course, all these things can be achieved if people do not have diseases. Prevention, however, is not enough. A person needs to have a diagnosis of his or her condition. The doctor will tell the patient what kind of diseases he or she is suffering from. Then the doctor will decide on what treatment is best.
People who have a disease, no matter what kind it is, can still lead a normal life if he or she is properly treated. People afflicted with certain diseases can also lead a normal and full life. With a proper diagnosis, a person can live a healthy and normal life. All he or she has to do is to get the right treatment.
