Why Do We Get Sick?

To be sick is to be unwell, mentally and physically. All of us have been physically unwell at one time or other. Some illnesses can be prevented while others are unavoidable.

People, like all life-forms on earth, are made up of cells. Every seven years virtually every cell in the body is replaced, some types of cells having a faster turnover rate than others, which means that over a seven year period several hundred pounds of dead cells must be digested and eliminated. In the environment, there are germs. Germs are either bacteria or viruses. The air we breathe can make us sick, especially if we live in urban areas. Water bearing parasites cause diarrhea and cholera. Even the food we eat to keep us alive can make us ill.

The feeling of being “sick” is really the human body fighting off a tiny, invisible invader: germs. Viruses are like little factory workers. Viruses can enter a cell and cause it to produce more viruses. Bacteria are also a kind of cell. However, bacteria do not usually enter cells. Instead, bacteria eat the matter that cells use or create.

Some unfortunate people are born with inherited diseases. This means that they have defective genes. There is also genetic hemophilia which is a bleeding disorder that interferes with the normal clotting of blood. The gene is passed from parent to child, hence cannot be avoided. Regardless of the genetic hand-of-cards dealt to each of us, the frequency with which we are overtaken by sickness is dependent on the decisions we make in our daily lives.
