Pathology (Key Terms)
Pathology - the study and diagnosis of disease through the examination of organs, tissues, bodily fluids and whole bodies (autopsy).
Disease – any condition that causes extreme pain, dysfunction, distress, social problems, and/or death

Causes of Disease

Causes of Disease
2 broad groups
(2) Non-infectious diseases – are not communicated from person to person and are not known to involve infectious agents. Some causes include:
» Heredity» Lifestyle (diet, stress, etc.)» Example: Diabetes Type II
![Page 7: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/7.jpg)
As You already knowBody’s Reaction to Disease
When pathogens successfully invade the body, the immune system immediately begins to destroy them
The spleen, lymph nodes, tonsils, thymus, lungs, liver, kidneys and entire lymphatic system gets called into action
Lymphocytes– The specialized white blood cells responsible for
combating infectious agents

Do you ever feel like you always seem to get sick at the worst
times??
Hmm, why do you think that is the
case?

STRESSDid you know….
75% to 90% of all visits to primary care physicians are for stress-related complaints up to 80% of on-the-job accidents are stress-related 40% of job turnover is due to stress Stress accounts for $26 billion in medical and disability
payments and $95 billion in lost productivity per year Over 50% of lost work days are stress related which
keeps about 1 million people per day from attending work
75% of employees believe the worker has more on-the-job stress than a generation ago
![Page 11: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/11.jpg)
WHAT IS STRESS? Stress is your mind and body’s response
or reaction to a real or imagined threat, event or change.
The threat, event or change are commonly called stressors. Stressors can be internal (thoughts, beliefs, attitudes) or external (loss, tragedy, change).
![Page 12: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/12.jpg)
Different Types of Stress
Eustress vs. Distress
![Page 13: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/13.jpg)
EUSTRESS
Eustress or positive stress occurs when your level of stress is high enough to motivate you to move into action to get things accomplished.
![Page 14: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/14.jpg)
DISTRESS Distress or negative stress occurs when
your level of stress is either too high or too low and your body and/or mind begin to respond negatively to the stressors.
![Page 15: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/15.jpg)
***In his work, Selye - 'the father of stress research,' developed the theory that stress is a major cause of disease because chronic stress causes long-term chemical changes.
He observed that the body would respond to any external biological source of stress with a predictable biological pattern in an attempt to restore the body’s internal homeostasis.
This initial hormonal reaction is your fight or flight stress response - and its purpose is for handling stress very quickly! The process of the body’s struggle to maintain balance is what Selye termed, the General Adaptation Syndrome.
General Adaptation Syndrome
![Page 16: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/16.jpg)
ALARM STAGE First reaction to stress: recognizes there’s a danger
and prepares to deal with the threat, a.k.a. the fight or flight response.
During this phase the main stress hormones cortisol, adrenaline, and noradrenaline, is released to provide instant energy.
If this energy is repeatedly not used by
physical activity, it can become harmful.
![Page 17: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/17.jpg)
FIGHT or FLIGHT Response
![Page 18: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/18.jpg)
Alarm Stage Continued
The excess production of the cortisol hormone can cause damage to cells and muscle tissues. Stress related disorders and disease from cortisol include cardiovascular conditions, stroke, gastric ulcers, and high blood sugar levels.
At this stage everything is working as it should – you have a stressful event, your body alarms you with a sudden jolt of hormonal changes, and you are now immediately equipped with enough energy to handle it.
![Page 19: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/19.jpg)
Stress Hormones Cortisol stimulates the release of glucose,
fats and amino acids into the bloodstream Cortisol levels lowest at night, highest
when you wake up. Under ideal conditions, your cortisol
levels should be neither consistently high nor low, but fluctuate in a fairly rhythmic pattern.
![Page 20: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/20.jpg)
RESISTANCE STAGE The body shifts into this second phase with
the source of stress being possibly resolved. Homeostasis begins restoring balance and a period of recovery for repair and renewal takes place.
Stress hormone levels may return to normal but you may have reduced defenses and adaptive energy left.
![Page 21: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/21.jpg)
Resistance Stage Con’t…
If a stressful condition persists, your body adapts by a continued effort in resistance and remains in a state of arousal.
Problems begin to manifest when you find yourself repeating this process too often with little or no recovery. Ultimately this moves you into the final stage.
![Page 22: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/22.jpg)
Changes to observe in Resistance stage
Behavior indicators include: lack of enthusiasm for family, school, work or life in general, withdrawal, change in eating habits, insomnia, hypersomnia, anger, fatigue.
Cognitive Indicators include: poor problem solving, confusion, nightmares, hyper-vigilance.
![Page 23: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/23.jpg)
Changes to observe in Resistance Stage
Emotional indicators include: tearfulness fear anxiety panic guilt agitation depression overwhelmed.
![Page 24: Intro to Pathology What comes to mind when you hear the term HEALTH? HEALTH](https://reader035.vdocuments.us/reader035/viewer/2022062421/56649e2e5503460f94b1ebeb/html5/thumbnails/24.jpg)
EXHAUSTION STAGE Your body’s ability to resist is lost because its
adaptation energy supply is gone. Often referred to as overload, burnout, adrenal fatigue, maladaptation or dysfunction
This stage of the general adaptation syndrome is the most hazardous to your health. Chronic stress can damage nerve cells in tissues and organs.

SOAP Method
1) Subjective data: obtained through conversation with patient. Thoughts, feelings, and perceptions
2) Objective data: apparent and measurable. Vital signs and test results
3) Assessment: the physicians diagnosis or impression of the patient’s problem
4) Plan of action: Options for treatment
