All of you may wish to have good health all your life long but in fact you cannot deny that any disease can undesirably visit us some day. Although we think that we are in good health why do we have some diseases when we get older? So what can guarantee that we are healthy? Nowadays, our body must confront various kinds of surroundings, such as food, water and diseases, which we rarely take into account. Eating some kinds of food too much can cause diseases, e.g. obesity, diabetes, high cholesterol, gout. Or even eating non-hygienic food can also cause diseases, e.g. hepatitis, gastrointestinal diseases, parasitic diseases, anemia, calcium-deficiency osteoporosis. Symptoms of illness can indicate body abnormality so that we can perceive them and go to see a physician in a timely manner. However, some illnesses occur internally and they do not show any symptoms, so it may be too late when we realize them. As a result, an annual health check up is considered essential in preventing diseases and getting timely medical treatment. |
