Science and technology have advanced to the point that we can identify the causes, symptoms, and remedies for numerous diseases with a high degree of success. This is backed up by much longer average lifespans and decreased death rates. If you want to know about different types of diseases, read on.
What is disease?
Diseases are frequently seen as medical disorders distinguished by their signs and symptoms. When a person is afflicted with an illness, he displays a number of symptoms and indications that range from mild to severe, depending on the medical condition. As a result, in order to detect different diseases, the normality of an entity must be investigated and understood, as the line between sickness and disease-free is not always obvious. Below is more about different types of diseases and their causes.
Viruses and Infectious Diseases
These illnesses are those that transfer from one person to another. They are often caused by pathogenic germs (fungi, rickettsia, bacteria, viruses, protozoans, worms). Pathogens may depart the host and infect a new individual when an infected person discharges body secretions (such as sneezing, or coughing etc). Cholera, chickenpox, malaria, and other diseases are examples.
Diseases that Aren’t Infectious
Pathogens cause these diseases, but other variables such as age, nutritional deficiencies, an individual’s gender, and lifestyle all have an impact on the condition. Hypertension, diabetes, and cancer are a few examples. They do not transmit to others and have a suffocating effect on the individual who has contracted them. Non-infectious illnesses include Alzheimer’s, asthma, cataracts, and heart disease.
One of the different types of diseases are degeneration related disease. They are mostly caused by the malfunctioning of important organs in the body as a result of cell degradation over time. Osteoporosis, for example, has degenerative disease symptoms in the form of increasing bone fragility. This raises the likelihood of bone fractures.
When the cells of the central nervous system degenerate then the situation is known as a neurodegenerative disorder. Alzheimer’s disease is a well-known example of this condition. Ageing and bodywear are the most common causes of degenerative diseases. Others are the result of lifestyle decisions, while others are inherited.
Allergies are one of the different types of diseases. When the body becomes susceptible to specific external chemicals known as allergens, an allergic response occurs. This generally occurs when the immune system overreacts to seemingly innocuous chemicals. Dust, pollen, animal dander, mites, feathers, latex, and certain food ingredients, such as nuts and gluten, are all common allergies. Peanuts and other nuts can trigger severe allergic responses that can result in life-threatening complications such as trouble breathing, tissues swelling up and clogging the airways, and anaphylactic shock.
Less serious symptoms
Other less serious symptoms include coughing, and runny nose, itchy and red eyes, and skin rashes. Asthma is a prime example of an allergic response. Bee stings and ant bites can also cause allergies. Consumption of shellfish alongside some medications may have an adverse effect.
Asthma is a chronic lung illness that mostly affects the bronchi and bronchioles. Airborne allergens are one of the causes of this. Breathing difficulties, wheezing, and coughing are all symptoms.
They are caused by a lack of hormones, and vitamins. Diabetes, for example, is caused by an inability to generate or use insulin; goitre is caused mostly by iodine shortage; and kwashiorkor is caused by a lack of proteins in the diet.
It is an abnormal growth of the thyroid gland that blocks the oesophagus or other chest and neck organs. This makes breathing and eating difficult.
Plasma, white blood cells, platelets, and red blood cells are all components of blood. When any of these components is harmed, it might result in blood problems. When a person has sickle cell disease, for example, the red blood cells are damaged. The red blood cells are deformed into the shape of a sickle (thus the name), and their capacity to transport oxygen is lost. As a result, symptoms comparable to chronic anaemia, such as weariness, define this condition.
Agents that cause disease
We have seen the categorization of diverse things based on various qualities; for simplicity, we categorize creatures in order to gather them together and study them as a class. Similarly, illnesses are produced by many microorganisms and may be classed as bacteria, fungus, viruses, and so on. Multicellular creatures, such as worms, can also cause illness.
