The disease is a condition which deteriorates the normal functioning of the body cells, tissues, and organs. Based on certain signs and symptoms, it is categorized as non–communicable and communicable diseases. Below listed are some common diseases with their symptoms.
- Acquired Diseases: They are acquired after the birth. They are grouped into two types. Communicable and noncommunicable.
- The communicable disease is caused by certain microorganisms called pathogens (fungi, rickettsia, bacteria, viruses, protozoans, worms) which lead to infections. This disease spread from one person to another and is called communicable disease. Few examples include Cholera, chicken pox, malaria etc.
- The non-communicable disease is caused by age, nutritional deficiency and sex of an individual, genetics and so on. Few examples include Hypertension, diabetes, and cancer. They do not spread to others and they restrain within a person who has developed them.
Cancer is caused by an uncertain growth of certain tissues in the body. It can be classified depending upon the type of the cell that has been affected initially. Tumors occur when a cancerous cell succeeds itself in dividing and making a new blood vessel to feed in a process namely angiogenesis. These cells also transport throughout the body by using a blood system, in turn, destroying the blood cells which are healthy. And this process is termed as an invasion.
No symptoms would occur when cancer begins. Some of the common types of cancer include breast cancer, colon cancer, cervical cancer, ovarian cancer, kidney cancer, liver cancer etc.
- Degenerative or Organic Diseases: They are mainly caused by the malfunctioning of vital organs in our body. For example heart disease or cardiovascular disease.
It is caused due to excessive smoking, alcohol consumption and lack of exercise. Common disorders include hypertensive heart disease, inflammatory heart diseases, cerebrovascular disease, valvular heart disease, ischemic heart disease and heart failure.
- Symptoms – sweating, weakness, nausea, difficulty in breathing and irregular heartbeats.
- Allergies: An allergic reaction arises when the body becomes hypersensitive to a certain foreign substance called allergens that come into contact with the substance. Common allergens include dust, pollen, animal dander, mites, feathers, latex and also certain food products. The symptoms include coughing, sneezing, running nose, itchy and red eyes, skin rashes, and difficulty in breathing. One of the best examples of this allergic reaction is the Asthma.
Asthma is a chronic disease, mainly affects bronchi and bronchioles of the lungs. One of the factors responsible for this is airborne allergens.
Symptoms – Difficulty in breathing, wheezing, and cough.
- Deficiency Diseases: They occur due to the deficiencies of hormones, minerals, nutrients, and vitamins. For example diabetes, goiter, kwashiorkor, beriberi etc.
It is an abnormal enlargement of the thyroid gland by blocking the esophagus or other organs of chest and neck. This causes difficulty in breathing and eating. Goiters are mainly caused by the Iodine deficiency in our body.
Some blood disorders may lead to cancer and some may not. It can also be caused due to blood proteins or even mainly due to platelets, red blood cells, and white blood cells. They include bleeding disorders, low blood platelets count, eosinophilic disorders, leukemia, myeloma (cancer of plasma cells in bone marrow), Sickle Cell Anemia, Aplastic Anemia, Hemochromatosis and Von Miller and Disease (blood-clotting disorder).
Symptoms- Pale skin, swelling of lymph nodes, fever, bleeding, bruising, skin rashes, etc.
Beneath are the list of some bacterial diseases and pathogens.
|Vibrio comma (Vibrio cholera)||Cholera|
|Bordetella pertussis||Whooping cough|
