Diseases Caused by Internal Malfunction

Instructor: Artem Cheprasov

Artem has a doctor of veterinary medicine degree.

Some think of the body as a temple. But what you must know is that this temple can actually destroy you through one of many ways. Find out how internal malfunction can cause disease.

Different Types of Disease

A nation can be broken apart from two very general directions. It can be attacked from the outside, as in a foreign military, or it can break down from within, as in internal economic collapse or revolution.

Similarly, your body can suffer from poor health as a result of a) external factors or b) internal malfunctions. By external factors, I largely mean infectious disease--those caused by viruses, bacteria, fungi, and parasites. These are organisms that come in from the outside (from the environment), make their way into your body and cause you all sorts of problems.

This lesson isn't about that, however. It's about diseases caused by internal malfunctions--when your body revolts against you without, necessarily, any outside cause.

Inherited Genetic Disorders

A nation can fall apart if it is poorly built, right? I mean, if the way the roads, sewage systems, socioeconomic structures, and so on, is designed, built, or maintained is faulty, then the nation is more likely to suffer from internal malfunctions.

One kind of internal malfunction in our body has to do with improper genetics, especially ones that are inherited from a person's parents. Genes are agents of heredity. They are the code by which your body is built and functions. If they are faulty, if their code is faulty, then your body may suffer from internal malfunctions. Some examples of this include:

  • Cystic fibrosis, a disorder that causes everything from the lungs to the pancreas to malfunction.
  • Hemophilia, a disorder that prevents a person's blood from clotting properly.
  • Duchenne Muscular Dystrophy, a disease that weakens a person's muscles.

Autoimmune Disorders

Nations can also be destroyed from within by something like a revolution, where the people, the inhabitants of the nation, rise up and set fire and destroy their own country or government.

This is similar to autoimmune disorders, which are disorders where the body's immune system attacks itself. The immune system is made up of many cells and proteins that inhabit your body. Normally, they go quietly about their day and protect you from foreign invaders like viruses and bacteria. However, they sometimes attack your own body en masse instead. The attack essentially sets your body on fire from within, either causing you significant discomfort or serious organ damage.

Diseases and disorders with an autoimmune component to them include:

  • Systemic lupus erythematosus (SLE), which causes joint pain and swelling.
  • Myasthenia gravis, which causes weakness of a person's voluntary muscles, or the ones that help them move about.
  • Type 1 diabetes, a disorder that raises a person's blood sugar and may, eventually, lead to other problems like kidney disease.


If the internal malfunction isn't caused by a poorly designed structure or revolution, then disgruntled citizens-turned-saboteurs may be to blame for a country's downfall. Unlike a revolution, where a lot of people rise up, you only need one or two successful saboteurs to cause serious damage. Our body's saboteurs are its own regular cells.
