A disease develops when the body does not function properly. Doctors usually diagnose a disease by reviewing a patient's medical history, performing a physical examination, and running tests. Even though "disease" may sound serious, it does not mean it is always life-threatening.
Some diseases are minor and resolve quickly; others can be serious and last a long time. Certain diseases cannot be prevented; however, some can be. Read more to learn how diseases affect your body and how to manage them while staying healthy.
There are numerous types of diseases, and they are usually grouped based on what causes them. Some common types of diseases and their examples include:
Here are some of the main practices that help to control several diseases:
1. Prevention
Numerous diseases can be prevented, except for some rare inherited ones. Diseases caused by environmental factors can often be prevented by reducing or removing those harmful factors. However, some cancers/environmental exposures are unavoidable. For infectious diseases, prevention usually means avoiding contact with sick people or making people immune through vaccines.
Quarantine can help, but it is not always effective. Some diseases spread through the air or animals are difficult to control, but others, like tuberculosis or bird flu, can be managed by treating patients or controlling infected animals.
Diseases spread by insects or contaminated water and food can usually be controlled by killing the insects or cleaning the water and milk.
2. Immunisation and Vaccination
Vaccines help protect people from many diseases, especially when other methods fail. Vaccinating children has helped control illnesses such as measles, polio, and hepatitis B.
They can also protect against certain cancers, such as cervical cancer linked to HPV (human papillomavirus). Sometimes, medicine is used to prevent disease spread when vaccines aren't available.
3. Treatment
Treating disease mainly focuses on helping the body recover and removing what's causing the illness. The body has natural ways to resolve and fight infections; treatments support these defences.
Some diseases caused by gene problems may one day be treated by gene therapy. If a disease is caused by toxins, avoiding exposure helps the body recover, and sometimes special medicines can help remove poisons like lead.
Infectious diseases are often treated with medicines like antitoxins or antibiotics. Sometimes, treatment is about resolving symptoms, like giving fluids for cholera. For viral infections, there are fewer medicines, so treatment mostly helps you feel better while your immune system fights the virus.
Diseases can affect anyone at any time and come in many forms, from minor illnesses to serious health conditions. Understanding how diseases start, how to prevent them, and how they are treated can help you stay healthier and protect your loved ones.
While many diseases can be prevented with simple steps such as good hygiene, healthy living, and vaccines, other diseases cannot be avoided. Thus, treatment may become inevitable and expensive, so having health insurance is a crucial step to secure your health and finances in the long term.
