Parasitic Diseases?

I've been reading and watching a lot about parasitic diseases. It seems like 1 out of 6 human beings are infected. I read about the symptoms but they sound like they can be confused with other illnesses. I've been to 3rd world countries and from my studies, that's where we get most of these parasites from. I know that it's hard to prevent yourself from being a host....it's not exactly what everyone is thinking about, it slips our minds. What should we do to find out if we're infected?

There are internal parasites and external parasites.
Internal parasites-Malaria, Filariasis, Pinworm, roundworm, hookworm, tape worm, etc
External parasites-Pubic lice, Head louse, Scabies, etc

we should get chect by a doctor

Diseases caused by protozoan and helminth parasites are among the leading causes of death and disease in tropical and subtropical regions of the world. Efforts to control the invertebrate vector (carrier, such as the mosquito) of these diseases are often difficult and no vaccines are currently licensed to prevent or control the spread of parasitic diseases

Go to your local doctor and get x-rayed or get your intestines cleaned!!! Your doctor will tell you what to do from there!
If you are infected then you will probably eat and eat even when you aren't hungry!

If you are not experiencing any symptoms the best thing to do is to get a stool sample. They are low cost and quick but not totally accurate because a small infection could be missed in the sample. They will visually inspect the stool under a microscope for little worms, eggs, etc. Also, many more than 1 out of 6 people is infected worldwide. Hookworms alone are thought to infect 800 million people worldwide (almost 1 in 6).
===========
Others are saying here that you will "eat and eat" but this is normally untrue. Many people with small infections have no clue they are infected. I had a relative that had a 20-30 foot tapeworm removed and he had it for quite some time before he knew anything was wrong. Think about it this way. If your body was made up of 1% worms by weight and you had to eat 5% more food to feed the worms would you even know you were eating the increased food? (numbers made up for illustration but you get the point).

Whenever you have symptoms of illness, get examined by your doctor. You won't know what the causative agent is, be it bacterial, viral, fungal or parasitic, until you do this. But you can't expect to get tested for parasitic infection if you have no symptoms unless you have a very good reason to suspect exposure.
