Title: Chapter 14- Lifestyle Diseases

Chapter 14- Lifestyle Diseases
  • Section 1- Lifestyle and Lifestyle Diseases
  • Section 2- Cardiovascular Diseases
  • Section 3- Cancer
  • Section 4- Living with Diabetes

  • At the end of this lesson, you will be able to
  • Describe how lifestyle can lead to disease.
  • Know the difference between controllable risk
    factors and uncontrollable risk factors.
  • Apply two actions they can do to lower their risk
    for developing a lifestyle disease later in life.

Lifestyle Diseases
  • Lifestyle diseases are diseases that are caused
    partly by unhealthy behaviors and partly by other
  • Examples atherosclerosis, heart disease, stroke,
    Type 2 diabetes, hypertension, many forms of
  • These diseases are the top causes of death in the
    United States

Risk Factor
  • When determining if a person might develop a
    disease, a doctor looks at a persons risk
  • A risk factor is anything that increases the
    likelihood of injury, disease, or other health
  • Controllable and uncontrollable risk factors

What Causes Lifestyle Diseases?
  • Certain habits, behaviors, and practices such as
    poor eating habits, inactivity, or smoking
  • Factors that we cannot control such as age,
    gender, and heredity

Controllable Risk Factors
  • These include habits, behaviors, and practices
    that we can change
  • Examples
  • Your diet and body weight
  • Your daily levels of physical activity
  • Your level of sun exposure
  • Smoking and alcohol abuse

Uncontrollable Risk Factors
  • Some risk factors that contribute to your chances
    of developing a lifestyle disease are out of your
  • Examples
  • Age
  • Gender
  • Ethnicity
  • Heredity

  • Acute- A disease that lasts for a short period of
    time. Examples flu, cold, strep throat.
  • Chronic- A disease that persists for a long time.
    Health damaging behaviors - particularly tobacco
    use, lack of physical activity, and poor eating
    habits - are major contributors to the leading
    chronic diseases.

  • What is a lifestyle disease?
  • A disease that develops partly from your
    lifestyle and partly by other factors
  • What things cause lifestyle diseases?
  • Smoking, tanning, unhealthy diet, overweight
  • What are the four controllable risk factors?
  • Sun exposure, activity level, diet,
    smoking/alcohol abuse

  • What are the four uncontrollable risk factors?
  • Age, heredity, gender, ethnicity
  • What does acute mean?
  • Short term illness
  • What does chronic mean?
  • Long term illness

Diseases Family Tree Assignment
  • You will create a family tree of diseases. Please
    include as many family members as possible. You
    will be responsible for drawing a web of family
    members and listing any diseases they had under
    their name.
  • Due Date Monday, November 8th
  • This assignment is worth 15 points.

Chapter 14 Section 2
  • Cardiovascular Diseases

  • At the end of this lesson, you will be able to
  • Summarize how ones lifestyle can contribute to
    cardiovascular disease
  • Describe four types of cardiovascular diseases
  • Identify ways you can lower your risk for
    cardiovascular diseases

Cardiovascular Diseases
  • Your heart and blood vessels make up your
    cardiovascular system.
  • The diseases that result from damage to your
    heart and blood vessels are called cardiovascular
  • Aka CVDs
  • Types of CVDs heart attack, stroke,
    atherosclerosis, and high blood pressure.

Risk Factors
  • Certain factors greatly increase your risk of
    developing a cardiovascular disease, these
    factors include
  • Smoking
  • Being overweight
  • High blood pressure
  • High blood cholesterol
  • Diabetes

Types of Cardiovascular Diseases
  • Stroke
  • High Blood Pressure
  • Heart Attack
  • Atherosclerosis

  • Sudden attacks of weakness or paralysis (loss of
    muscle function) that occur when blood flow to an
    area of the brain is interrupted.
  • Affects the arteries leading to and within the
  • Stroke is the third leading cause of death in the
    United States, behind diseases of the heart and

High Blood Pressure
  • The force that blood exerts against the inside
    walls of a blood vessel.
  • When blood pressure is too high, it puts extra
    strain on the walls of the vessels and on the
  • Many people do not know their blood pressure is
    high until they have a heart attack or stroke.

Blood Pressure
  • Blood pressure is expressed as two numbers
  • Systolic pressure- pressure found in the arteries
    while the heart muscles are contracting
  • Diastolic pressure- pressure of the blood as it
    continues to flow through the arteries between
    heart beats
  • Normal blood pressure falls between 80/50 and
    130/85 mm Hg
  • Blood pressure over 140/90 is considered high

Heart Attack
  • A heart attack is when blood vessels that supply
    blood to the heart are blocked, preventing enough
    oxygen from getting to the heart. The heart
    muscle dies or becomes permanently damaged. Most
    heart attacks are caused by a blood clot that
    blocks one of the coronary arteries. The coronary
    arteries bring blood and oxygen to the heart. If
    the blood flow is blocked, the heart starves for
    oxygen and heart cells die.

  • This disease is categorized by the buildup of
    fatty materials on the inside walls of the
  • It is dangerous for 2 reasons
  • 1. It can reduce or stop blood flow to certain
    parts of the body
  • 2. These deposits can break free and release
    clots into the bloodstream

Detecting CVD
  • Check blood pressure
  • Electrocardiogram
  • Ultrasound
  • Angiography

Treating CVD
  • Diet and exercise
  • Medicines
  • Surgery
  • Angioplasty
  • Pacemakers
  • Transplants

Preventing CVD
  • Limit consumption of fat and salt
  • Keep your weight near recommended levels
  • Dont smoke
  • Get moving
  • Have your blood pressure and cholesterol checked
  • Relax

Turn to page 344
  • You are going to write a brief description of
    each cardiovascular disease described.
  • You are teaching this material to elementary
    school children.
  • How would you write it so they understand the
    four different CVDs?
  • Be creative!

Chapter 14 Section 3
  • Cancer

  • Cancer- a disease caused by uncontrolled cell
  • More than one million people in the United States
    are diagnosed with cancer every year.
  • Cancer is the second leading cause of death
  • Cancer is more common in adults, but teens can
    get some forms of cancer.

What is Cancer?
  • Cancer occurs when cells begin to grow and
    multiply in an uncontrolled way
  • Normal body cells grow and divide over a period
    of time until they eventually die
  • But cancer cells continue to grow and divide and
    grow and divide
  • Eventually they gather to form tumors

  • Tumors are lumps that can interfere with the
    bodys normal processes
  • Malignant tumor is a mass of cells that invades
    and destroys healthy tissue
  • When a tumor spreads to the surrounding tissues,
    it eventually damages vital organs
  • Benign tumor is an abnormal, but usually harmless
    cell mass

Cancer Cells
  • Cancer cells are very destructive to the body,
    they tear through and crush neighboring tissues,
    strangle blood vessels, and take nutrients that
    are needed by healthy cells.
  • Cells can travel, this is called metastasis.

What Causes Cancer?
  • Genetics
  • Carcinogens
  • Certain viruses (HPV)
  • Radioactive and ultraviolet radiation
  • Chemicals found in tobacco smoke
  • Asbestos

Types of Cancer
  • Breast, prostate, respiratory, colon, urinary,
    lymphoma, skin, leukemia, ovarian, nervous
    system, cervical
  • There are over 100 different types of cancer

How do people know if they have cancer?
  • Extreme exhaustion
  • Swelling or lumps in certain parts of the body
  • Headaches
  • Blurred vision
  • Nausea
  • Problems with walking or balance
  • More infections
  • Unusual bleeding

Detecting Cancer
  • Self-exams
  • Biopsy
  • X rays
  • MRI
  • Blood and DNA tests

Treating Cancer
  • Surgery- an operation can remove some tumors
  • Chemotherapy- use of drugs to destroy cancer
  • Radiation therapy- a beam of radiation is fired
    at the tumor from outside the body
  • Often doctors recommend a combination of surgery,
    chemotherapy, and radiation

  • The success of any treatment depends on the type
    of cancer, how long the tumor has been growing,
    and whether the cancer has spread to other parts
    of the body
  • How can you help a person who has cancer?
