Introduction to Diagnosing Human Diseases and Conditions
The definition of disease in humans is an abnormal condition that causes illness, pain, distress, or negative lifestyle changes within the person it affects. Human diseases and conditions are now quite common in today's society, and they can occur for a large number of reasons. These reasons include:
- Infections from bacteria: Such as diarrhea
- Mental or physical disturbances: Such as depression or a broken leg
- Viruses causing illness: Such as the flu
- Conditions that come from a poor lifestyle: Such as obesity
The first step towards diagnosing human diseases and conditions is recognising that something is wrong. This is known as symptoms appearing, and the symptoms that appear will depend on the type of disease that you have and what has caused it. Each type of symptom will be different, for example if you have a bacterial disease you might notice that you have a fever of 104 degrees or more. For those who have viral infections, aches and feeling tired a lot are two common symptoms.
Physical and mental disturbances will show different symptoms depending on what has happened to you. Those who have depression may display symptoms such as feeling sad or anxious a lot. If someone has chronic back pain, they may find it difficult to walk or sit in certain positions.
Finally, those who have a disease or condition because of their lifestyle factors may display symptoms over a long period of time. For example, if you have a condition such as obesity you will gradually notice your weight increasing, or your clothes stop fitting.
Once you have recognised some symptoms, it is a good idea to visit your family physician. Before you go, write down what it is that you have noticed before you see them. By giving them the complete picture of your symptoms, they will find diagnosing which of the human diseases and conditions you have much easier. Make a short list if you find remembering what symptoms you have displayed hard, then take it to your physician.
When you see your family physician, you will find that he or she carries out some basic checks. The checks used to diagnose human diseases and conditions can include the following:
- Taking your temperature
- Weighing you
- Taking your blood pressure
- Testing your urine for bacteria or chemical imbalances
- Testing your blood to see if your sugar levels are high
It is important that you let your physician carry out all these tests, as they will help him figure out the cause of your disease or condition faster.
After your physician has carried out his tests, you may have to wait a little while for the results. With tests such as weighing and checking your blood pressure, they should be able to give you the results on the same day, but they may call you back for repeat tests.
If you do have to wait a while for the result of blood tests, take some time to see if you can modify any of your lifestyle factors that may make you unhealthy. This basically means eating well, drinking plenty of water, cutting down on tobacco and alcohol, and exercising. Many human diseases and conditions can be cured or alleviated by taking these simple steps towards changing your lifestyle.
Once you have received your test results, you may now either receive treatment or be referred for further tests. If your doctor has determined that you have a bacterial infection or viral infection, he may do the following:
- Advise you on healthy living
- Prescribe medication or antibiotics
- Advise you to rest.
If your doctor feels that you need further investigations, he may take more steps to diagnose you. Many human diseases and conditions are complex, which means that they need further diagnosis.
If your physician feels that further diagnostics will be of benefit to you, you may be referred for one of the following:
- An ECG to monitor your heart accurately.
- An x-ray to see what is happening inside your body.
- A CT scan to see what is happening in more detail in a specific area of your body.
- An MRI to see what is happening throughout your body.
Once you have had the results of these tests back, your physician will be able to offer a more accurate diagnosis. The majority of human diseases and conditions can be diagnosed with these measures.
Finally, if you feel that you would rather test which of the many human diseases and conditions you have for yourself, a wide variety of home testing kits are now available. These range from home pregnancy, infertility and STD tests, to routine home monitoring equipment. It is now possible for human diseases and conditions such as high blood pressure and diabetes to be monitored and diagnosed from home. This can be done by using home blood pressure monitors and blood glucose kits.
Tips for People Who Want to Diagnose Human Diseases and Conditions at Home
Diagnosing human diseases and conditions from home does not need to be difficult. Although it is always a good idea to let your family physician make the final diagnosis, there are things that you can do for yourself too. First, become familiar with your symptoms online. There are symptom checkers and websites that are ideal for doing this, as they allow you to enter your symptoms so that you can see what is wrong with you.
It is always a good idea to invest in kits for diagnosing diseases that are easy to use and come with simple instructions. Once you have done this, make sure you read the instructions properly and use the tests accordingly.
