A disease is an abnormal health condition that affects a living organism. Diseases are generally understood to be medical conditions that involve a pathological process associated with a specific set of symptoms.
A disease is a particular medical condition that hurts the structure or function of all or part of an organism, and that is not due to any immediate external injury. Diseases are often known to be medical conditions that are linked with certain signs and symptoms.
Types of Disease include.
There are four major types of disease. They include:
• Infectious diseases
Infectious diseases are disorders caused by organisms like bacteria, viruses, fungi or parasites.
• Deficiency diseases
These are illnesses linked with an insufficient supply of one or more essential dietary nutrients.
• Hereditary diseases
A hereditary disease is often described as something that affects a family. It is passed down from one or both parents to a child, who may then pass it to his or her children.
• Physiological diseases
These are diseases that can be caused by several abiotic factors such as high temperatures, low soil pH, phytotoxicity caused by agricultural chemicals.
Some of the diseases can lead to death. They include the following:
1. Cardiac arrest
Sudden cardiac death is a sudden, unexpected death caused by sudden cardiac arrest (loss of heart function).
Sudden cardiac death occurs most frequently in adults in their mid-30s to mid-40s and impacts men twice as often as it happens in women.
A stroke occurs when the blood supply inside the brain is affected, thus killing brain cells. If this occurs in a part of the brain that controls the body's automatic 'life support systems such as breathing and heartbeat, it can lead to death.
Cancer can lead to death when it impacts essential organs, such as your liver, lungs, or brain, and stops them from functioning properly. This medical condition could be due to primary cancer that occurs in your vital organ, such as brain cancer.
4. High blood sugar
High blood sugar can cause severe diabetes coma or even death. According to the American Diabetes Association, ketoacidosis affects people with type 1 diabetes, but it rarely impacts people with type 2 diabetes.
Hypertension makes your heart work harder to pump blood to the rest of your body. This makes part of your heart thicken. A thickened left ventricle increases your risk of heart attack, heart failure and sudden cardiac death.
