Our body is made up of thousands of different parts. All these parts work together to keep us alive and to help us move around. The parts of the human body are like the parts of a very complicated machine. Like any other machine, however, if it is inexpertly cared for, over-taxed or insufficiently used, it will become rusty, sluggish or clogged and parts of its mechanism may even grind to a halt. That is why it is so important to keep every part of the human machine healthy and properly cared for. To keep in good running order, the body requires the raw materials for growth and the replacement of tissues when necessary. Our bodies burn food like fuel to produce the energy we need.

The human digestive system is a bit like a very long tube, but it's a lot more complex. It's several meters long, and most of it is carefully coiled up in our abdomen. It has several important jobs to do.

First, it must digest or break down our food. Digestion starts the moment food enters our mouth. Then it continues as the food is squeezed along the gut by muscles in the wall of the intestine. As the food travels through the gut, natural chemicals called enzymes are added to it, which help break down the food. Then this digested food and water must be absorbed from the gut into our blood stream so that it can be used by the body. Finally, the gut must carry away any waste products in the form of feces.

Usually our intestine does all these things very efficiently. But sometimes things can go wrong. Probably the most common gut symptoms are diarrhea and constipation.

With diarrhea, the food and water travels too quickly through the intestine, often making the feces watery, and making it necessary to open the bowels more frequently.

There are lots of causes of diarrhea. Probably the commonest causes of diarrhea are contaminated food or water, and infection caused by viruses or parasites.

Many cases of diarrhea clear up within a few days without any special medicines. But the body loses a lot of fluid through diarrhea, so there is a very real risk of the body drying out or becoming dehydrated. Because of this risk of dehydration, the best treatment for diarrhea is simply to make sure you are drinking enough. Avoiding dehydration in this way can be a life saver.

B. Complete the statements. Causes of diarrhea

·There are infections, and this is food poisoning, which is caused by sort of bacteria or organism.

·Some foods themselves might irritate the gut and tend to give you diarrhea. ·Some people when they get very nervous ad stressed about something tend to get diarrhea.

or two days.

·The most important thing is to drink lots of fluid.

·It is better not to eat too much and not to worry about that.

·Ideally, the fluids you drink should contain a little bit of salt and sugar. ·You can get special rehydrating fluids, which are specially mixed.

·You can get your own fluids by adding just a teaspoonful of sugar and a pinch of salt. Tapescript:

There are lots of different causes of diarrhea. Um, there are infections that can happen, and this is food poisoning, if you like, where in your food you eat some sort of bacteria or organisms, which infect you. Some foods can just irritate the gut and tend to give you diarrhea, although they are not infected. It's just the food itself (that) might irritate your system. Some people, if they get very nervous and stressed about something, find they tend to get diarrhea. Something called the irritable bowel syndrome where something goes wrong with the way the gut works. And people that suffer from this tend to get, um, tummy pains, and they get sometimes diarrhea, sometimes constipation. All sorts of causes.

Most attacks of diarrhea, um, particularly in adults, are not serious and they clear up by themselves within one or two days. The most important thing is to drink lots of fluid, because if you have got diarrhea, you're obviously losing a lot of fluid. And so it's better really not to eat too much, not to worry about that, but to make sure you drink plenty of fluid. And ideally, this should have a little bit of salt and sugar in.
