What Does Disease Look Like?

There are various factors that influence whether a disease can be mild or deadly. We say we are struck with a disease when we feel some change or abnormality in our body which has a negative impact on our normal functioning. It drains us out of energy and disables us from performing daily chores.

Symptoms of a disease

When we fall sick, we exhibit certain signs of discomfort. These signs are called symptoms and help in the diagnosis of a disease. Some common symptoms are:

  • Headache
  • Fever
  • Nausea
  • Diarrhoea
  • Cold
  • Cough
  • Loss of appetite

Disease affects the organ system

Tissues make up the organ systems that are responsible for carrying out many bodily functions. Organ systems, in turn, are made up of organs specialized in carrying out specific functions. So, nostrils lead to lungs which are a part of the respiratory system, the digestive system includes the stomach and intestines which carries out digestion in our body, the musculoskeletal system consists of bones and muscles. It provides structure, posture and is responsible for body movements.

Diseases are caused due to various factors

Diseases can be caused due to external or internal factors. Internally, diseases can be caused due to genetic factors or because of a poor lifestyle such as diabetes, high blood pressure, PCOD etc. Autoimmune diseases such as multiple sclerosis are also triggered internally. Some other diseases are caused due to external factors such as pathogens carrying diseases. For example, Dengue is a mosquito-borne viral disease caused by female infected Aedes mosquito, Malaria is caused by parasites of the Plasmodium genus.

Many serious diseases have symptoms common with other illness, therefore they can be misjudged by us. Hence, the accurate diagnosis of a medical condition after careful supervision by an experienced physician or a doctor is important.
