Diseases are a natural part of life. In fact, there are more than 2,000 different diseases in the world today. Diseases are caused by many different things, including bacteria, viruses, and parasites. Some diseases can be prevented, while others can be treated. If you have a family history of disease, it’s important to learn about them so that you know what your risks are.
1. Cancer: Cancer is a serious disease that affects nearly 1 out of 3 people in the United States. It’s estimated that over 1 million people will be diagnosed with cancer this year. Cancer begins when cells become abnormal and begin to grow uncontrollably. The abnormal cells can spread to other parts of the body and cause damage. There are many types of cancer, and they are named according to where they begin. For example, breast cancer starts in the breast, and lung cancer starts in the lungs.
2. Heart Disease: Heart disease is the leading cause of death in the United States. Over 600,000 Americans die each year from heart disease. This is why it’s so important to learn about heart disease and how to prevent it. Many factors can contribute to heart disease, such as high blood pressure, smoking, and cholesterol levels. High blood pressure causes the arteries to become weak and narrow. When the arteries are narrowed, the heart has to work harder to pump blood through them. Smoking causes the arteries to become clogged and prevents oxygen from reaching the heart. Eating foods that are high in cholesterol increases the amount of fat in the blood.
3. Diabetes: Diabetes is a serious disease that affects more than 10 million people in the United States. Diabetes is caused by a lack of insulin. Insulin is a hormone that allows the body to use sugar for energy. People with diabetes have a very difficult time regulating their blood sugar levels. They also have an increased risk of developing complications such as blindness, kidney failure, and nerve damage. Diabetes is usually diagnosed by testing the level of sugar in the blood.
4. Stroke: Strokes occur when a blood vessel in the brain bursts or leaks. A stroke can be caused by a clot that blocks the flow of blood to the brain. Blood vessels in the brain can also burst because of a build up of plaque on the inside of the artery walls.
5. Kidney Failure: Kidney failure occurs when the kidneys stop working properly. The kidneys are responsible for filtering the blood and removing waste products. Without a functioning kidney, the body cannot get rid of waste products, and this can lead to a buildup of waste in the blood. This can eventually cause problems with the liver, heart, and lungs.
6. Asthma: Asthma is a chronic condition that causes breathing difficulties. People with asthma often wheeze or cough. Asthma is caused by allergies and inflammation in the airways.
7. Arthritis: Arthritis is a common condition that causes pain and stiffness in the joints. The most common type of arthritis is osteoarthritis, which occurs when the cartilage in the joint wears down. Osteoarthritis is more common in older adults.
8. Alzheimer’s Disease: Alzheimer’s disease is a form of dementia that causes memory loss and confusion. It usually occurs in older adults.
9. Parkinson’s Disease: Parkinson’s disease is a neurological disorder that causes shaking and difficulty walking. It usually occurs in older men.
10. Depression: Depression is a mood disorder that causes feelings of sadness and hopelessness. Depression is a common problem in children and adults.
There are many different ways to treat and prevent diseases. Some diseases are completely preventable, while others can be treated.
