Sometimes it’s not even that easy to tell whether
someone is sick since what’s normal for one person
could be bad for someone else. But generally
speaking there are many ways to get sick which are
almost certainly a problem for everyone. Two
main categories of sicknesses are those caused
by a different organism, such as an infection, and
those that aren’t related to an infection.
Infection based diseases are generally due to
bacteria, viruses, and occasionally more
complicated organisms known as parasites.
Bacteria can release chemicals that
interfere with our body and most of them can be
killed by antibiotics. The way viruses
reproduce naturally kills cells which makes us
sick and the best way to get rid of them is to let
your body’s defenses destroy them. The way we
instruct our body how to deal with a virus
is through a vaccine. Parasites are
more complicated, such as worms or the
parasite that causes malaria. Since they’re more
complicated, there are general drugs that can
usually get rid of them.
Parasites are most common in parts of the
world where people don’t have much money (poor
countries) and don’t live in clean conditions.
A second broad category of sicknesses are those
that don’t have anything to do with another
organism. In these cases, the sickness is
generally due to something in your body not
working right or something that has broken
down. An example of this would be Type II
Diabetes where someone’s cells don’t respond
to insulin as well as they should which causes a
lot of problem. Another example would be
cancer where a single cell gets mutated so
much that it starts growing like crazy which kills
normal cells. There are many, many diseases in
this category since every system in the body that
works, can break down, and does break down in some
people. Generally, to get rid of these types of
sickness, you need to either fix the parts of the
body that are failing or somehow deal with the
symptoms or results of the disease. There are a
lot of diseases that we can’t do much about since
we either don’ know what’s wrong, can’t fix what’s
wrong, or can’t deal with the symptoms of the
disease. There are about 30,000 known
diseases and we can effectively treat about 10,000
of them. So it would take a very long time to
talk about all the ways we can get sick! Also,
keep in mind that with so many diseases that we
can’t treat, there’s going to be opportunities for
doctors and scientists to try and work on these
problems for a long time.
What a great question! This is a big one!
There are quite a few ways a human can become
sick. This includes;
· Animal toxins
· His/her own body
Now, how to get rid of these gets a little more
complicated. We usually use medication for
every single way the human body can become sick.
Antibiotics - help the body's immune
system to destroy bacteria.
Antivirals - help kill viruses
Anti-fungal - to help kill fungus infections
Antidotes - these help neutralize toxins
from eukaryotes (spiders/snakes/etc.) or to
neutralize toxins from fungi such as certain
drugs, etc. - these methods help get rid if
illnesses that the body has when the body
I wish I could say there was a cure-all drug.
However, every category has its own difficulties.
Bacteria can multiply really quickly and thus
their biology changes rather quickly as well.
We have antibiotic resistant bacteria that will
not respond to medicine. Not all viruses have
anti-virals that help against them. We have the
common flu shot but that is the best guess that
the scientists believe will be prevalent that
year. The common flu can come in so many different
strains that the flu shot might not protect you
against it, but scientists do their best with
statistics and knowledge to pick the most
plausible choices for the year. Cancer is a huge
one as well. There is no "cure-all" for
cancer as cancer can be caused by so many
different pathways inside of the human body.
I hope I answered your question!
