Noncommunicable Disease

Noncommunicable Disease

is a disease that is not spread through contact.

Noncommunicable Disease

Are caused by how people live, conditions they are born with, or environmental hazards.

Noncommunicable Disease

Are not spread by contact because most are not caused by germs. Instead they are the breakdown in body cells and tissues.

Degenerative Diseases

Cause further breakdown, or degeneration in body cells and tissues as they progress

Chronic Diseases

Are present either continuously or off and on over a long period of time. May develop as a result of a person’s lifestyle behaviors or substances in a person’s environment

Diseases Present at Birth

Genetic Disorder,Birth Defect

Genetic Disorder

one in which the body does not develop or function normally because of an inherited problem

Birth Defect

disorders of the developing and newborn baby, causes unknown

Diseases Resulting from Lifestyle Behaviors

Many diseases are the direct or indirect result of harmful lifestyle behaviors. Healthful lifestyle behaviors, on the other hand, can help prevent or control certain diseases and disorders.

Diseases Caused by the Environment

Examples of harmful substances that may be present in the environment: Fumes for chemicals, second hand smoke, radon, asbestos

Epidemiological

NCDs overriding infectious diseases and double burden of diseases in many developing countries.

Lifestyles

tobacco use is increasing, diets are rapidly changing, physical activity reduces, alcohol use increases, obesity, hypertension are increasing in most parts of the world, while undernutrition remains a severe issue

COMMUNICABLE DISEASE

• Sudden onset

• Single cause

Short natural history

• Cure is achieved

• Single disciple

• Short follow up

NONCOMMUNICABLE DISEASE

• Gradual onset • Multiple etiology • Long natural history • Care predominates • Multidisciplinary • Prolonged follow-up

Heart Disease

the #1 killer of adults in the US!

Heart Disease

includes any condition that lessens the strength or function of the heart or blood vessels. • Healthy lifestyle behaviors lower risk of heart disease

coronary arteries

The arteries that supply your heart muscles with blood are called

Atherosclerosis

condition in which fatty substances (ex- cholesterol) in the blood are deposited on the walls of the arteries

Cholesterol

a fatty substance that causes that causes atherosclerosis, some cholesterol is produced by the body, certain foods also contain cholesterol

Arteriosclerosis

hardening of the arteries. Slows flow of blood and is a major cause of high blood pressure.

heart attack.

When a coronary artery is blocked, the result can be

stroke

When an artery in the brain is blocked the result can be a

Blood Pressure

force of the blood on the inside walls of the blood vessels.

110/70

Typical blood pressure for teens is

Hypertension (high blood pressure)

when the blood pressure is consistently higher then normal.

4 factors that increase your chances of having high blood pressure

• Eating a large amount of salt • Being overweight • Feeling extreme stress for long periods of time • Having a family history of high blood pressure

Risk Factors for Heart Disease – Not within a person’s control:

• Age • Gender • Race • Family history

Within a person’s control:

• Weight • Exercise • Diet • Tobacco

Heart Transplant

replacing diseased heart with healthy heart from a donor

Bypass Surgery

remove a vein from the leg and form a detour around the blockage

Dissolving Blood Clots

medications are used to dissolve the clots

Treating Heart Disease

– Angioplasty – Medication – Changing Lifestyle Behaviors

HYPERTENSION (HPN)

is defined as sustained elevation in mean arterial pressure. It is not a single disease state but a disorder with many causes, a variety of symptoms and a range of responses to therapy

Primary HPN

has no definite cause

Secondary HPN

usually result of some other primary diseases leading to HPN such as renal disease

Coronary Artery Disease (CAD)

• it is also known as Ischemic Heart Disease

• when the coronary arteries become narrowed or clogged, supply of blood and oxygen to the heart muscle is affected

• when there is decreased oxygen supply to the heart muscle, chest pain occurs (angina)

• can cause myocardial infarction (heart attack), arrhythmias, heart failure and sudden death

Modifiable risk factors

• High lipid and cholesterol level in the blood = high LDL • Smoking • Obesity • Physical inactivity or sedentary lifestyle • Stress

Non-modifiable risk factors

• Hereditary or family history • Gender • Age

Cerebrovascular Disease or Stroke

Loss or alteration of bodily function that results from an insufficient supply of blood to some parts of the brain. If blood is obstructed for more than several minutes, injury to the brain cells becomes permanent and tissue dies in the affected region resulting in cerebral infarction

Three types of stroke

Thrombotic stroke ,Embolic stroke, Hemorrhagic stroke

Thrombotic stroke

usually occurs in atherosclerotic blood vessel commonly seen in older people

Embolic stroke

caused by a moving blood clot usually from a thrombus in the left heart that becomes lodged in a small artery through which it cannot pass

Hemorrhagic stroke

most fatal type of stroke, rupture of intracerebral blood vessel

CANCER

• develops when cells in a part of the body begin to grow out of control.

• continue to grow and divide even when there is no need to do so. Instead of dying they outlive normal cells and continue to form new abnormal cells. They compete with normal cells for the blood supply and nutrients

metastasis

Cancer cells often travel to other parts of the body where they begin to grow and replace normal tissue

Causes of cancer

• Hereditary/family history

• Carcinogens

• Polycyclic hydrocarbon

• Benzopyrene

• Nitrosamine

• Radiation

• Viruses

• Aflatoxin

Carcinogens

agent capable of causing cancer, maybe chemical, environmental agent, radiation

Polycyclic hydrocarbon

are chemicals found in cigarette smoke, industrial agents and in smoked foods

Benzopyrene

produced when meat and fish are charcoal broiled or smoked, also produced when food is fried in fat that has been reused repeatedly

Nitrosamines

powerful carcinogens used as preservatives in foods like tocino, longganisa bacon, hotdogs

Radiation

UV rays from sunlight, x-rays

Aflatoxin

found in peanuts and peanut butter

Cancer

2nd leading cause of death in adults in the US

– Involve abnormal body cells growing out of control.

– Many different types of cancers that affect most parts of the body.

Tumors (groups of abnormal cells)

Benign and Malignant

Benign Tumor

tumor that are not cancerous

Malignant Tumor

tumor that are cancerous

Diagnosing Cancer

• Routine Physical Examination • Blood Tests • Biopsy- small piece of tissue is removed for testing in a lab

American Cancer Society

There are 7 warning signs of cancer identified by the blank

Warning Signs of Cancer

Change in bowel or bladder habits

A sore that does not heal

Unusual bleeding or discharge

Thickening or lump in breast or elsewhere

Indigestion or difficulty swallowing

Obvious change in a wart or mole

Nagging cough or hoarseness

Surgery

remove cancer cells from the body

Radiation

X-rays, or other radioactive substances are aimed at a tumor

Chemotherapy

chemicals are used to destroy cancer cells

Lung cancer

Tobacco smoking, second hand smoke, radiation exposure

DIABETES MELLITUS

Genetically and clinically heterogeneous group of metabolic disorder characterized by glucose intolerance with hyperglycemia present at time of diagnosis

TYPE I – Insulin Dependent Diabetes Mellitus (IDDM)

• Characterized by absolute lack of insulin due to damaged pancreas • Dependent of insulin injections • Genetic, environment or maybe acquired

TYPE II – Non-Insulin Dependent Diabetes Mellitus (NIDDM)

• More common, 90-95% of all person with diabetes • More preventable because it is associated with obesity and diet • Possible cause include impaired insulin secretion and increased hepatic glucose production • Usually in older and overweight persons

GESTATIONAL DIABETES

develops during pregnancy and may lead to Type II DM

CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD)

Major cause of chronic morbidity and mortality worldwide

– 4th leading cause of mortality.

It is a disease characterized by airflow limitation that is not fully reversible.

The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases
