The Big Picture
Your endocrine system contains glands that release hormones. These chemical messengers affect other organs and glands and help your body function.
An endocrine disorder occurs when hormone levels become too high or too low. Diabetes is the most common endocrine disorder. Thyroid disorders also change hormone levels and affect how quickly body processes work.

Course Notes: Key Ideas You Need to Know
How the Endocrine System Works
The endocrine system contains glands that release hormones. Hormones act as chemical messengers and affect other organs and glands.
The body needs hormones for normal body function. Endocrine disorders develop when the body has too much or too little of a hormone.
Understanding Diabetes
Diabetes affects the way the body produces or uses insulin.
The pancreas produces insulin. Insulin helps sugar, or glucose, from food enter the cells. The cells use this sugar for energy.
Without enough insulin, sugar builds up in the blood. This condition is called hyperglycemia, which means high blood sugar.
When cells lack sugar for energy, they do not perform their functions properly. Left untreated, mild hyperglycemia can lead to long-term complications. Severe hyperglycemia becomes life-threatening.
More than nine million Canadians live with diabetes or pre-diabetes. About 10% of people with diabetes have type 1 diabetes.
The Three Types of Diabetes
Type 1 Diabetes
Type 1 diabetes occurs most often in children and young adults, although it occurs at any age.
The pancreas does not produce insulin. This lack of insulin leads to severe hyperglycemia.
People with type 1 diabetes develop symptoms early in the disease. They need daily insulin injections.
Type 1 diabetes sometimes carries the name insulin-dependent diabetes mellitus, or IDDM.
Type 2 Diabetes
Type 2 diabetes usually develops in adulthood, although children also develop it. It is the most common type of diabetes.
Two problems occur with type 2 diabetes:
- The pancreas does not produce enough insulin.
- The body does not use the insulin it produces effectively.
Risk factors include:
- obesity
- family history
- age over 40 years
Almost 80% of Canadians come from populations identified as having higher risk for type 2 diabetes. These populations include Indigenous, Latin American, Asian, South Asian, and African descent.
Hyperglycemia with type 2 diabetes often stays mild enough that the client does not notice symptoms.
Treatment often includes diet and exercise or oral medications. Some clients also require insulin.
Type 2 diabetes sometimes carries the name non-insulin-dependent diabetes mellitus, or NIDDM. This name creates confusion because some people with type 2 diabetes need insulin.
Gestational Diabetes
Gestational diabetes develops during pregnancy. It usually disappears after the baby is born.
A woman who experiences gestational diabetes has a higher risk of developing type 2 diabetes later in life.
Common Signs and Symptoms of Diabetes
Common signs and symptoms include:
- increased thirst
- frequent urination
- constant hunger
- unusual weight loss
- extreme fatigue
- dry, itchy skin
- blurred eyesight
Insulin and Blood Sugar
People with type 1 diabetes require insulin injections, usually one to four times each day. Some people with type 2 diabetes also need insulin.
Most clients give themselves their insulin.
Clients must take the exact insulin type and dose ordered by the physician. Correct insulin use helps prevent complications from insulin therapy.
Too much insulin leads to hypoglycemia, which means low blood sugar.
If hypoglycemia is not corrected by intake of sugar, it can lead to coma or death.
Report: Immediately report signs and symptoms of hyperglycemia or hypoglycemia to your supervisor.
Hyperglycemia: High Blood Sugar
Several factors lead to hyperglycemia:
- undiagnosed diabetes
- too little insulin or diabetes medication
- overeating or eating the wrong kinds of food
- too little exercise
- physical or emotional stress
Warning signs and symptoms include:
- tiredness or fatigue
- hunger
- thirst
- frequent urination
- leg cramps
- blurred vision
- dry, itchy skin
- flu-like achiness
- sweet breath odour
- headache
- flushed face
- rapid, weak pulse
- low blood pressure
- slow, deep, laboured breathing
- confusion
- nausea and vomiting
- convulsions
- loss of consciousness
Hypoglycemia: Low Blood Sugar
Several factors lead to hypoglycemia:
- too much insulin or diabetes medication
- skipping or delaying a meal or snack
- eating too little food
- too much exercise
- vomiting
Warning signs and symptoms include:
- hunger
- weakness
- trembling or shakiness
- sweating
- headache
- dizziness
- faintness
- irritability or anxiety
- confusion or disorientation
- rapid pulse
- low blood pressure
- rapid, shallow breathing
- changes in vision
- cold, clammy skin
- unconsciousness
- convulsions
Hyperglycemia and Hypoglycemia: Key Differences
Both conditions involve abnormal blood sugar, but they have different causes and warning signs.
Hyperglycemia means high blood sugar. Too little insulin or diabetes medication, overeating, too little exercise, and stress appear among its causes.
Hypoglycemia means low blood sugar. Too much insulin or diabetes medication, missed or delayed food, too little food, too much exercise, and vomiting appear among its causes.
Some warning signs overlap. Hunger, headache, low blood pressure, confusion, pulse changes, vision changes, unconsciousness, and convulsions appear in the lists for both conditions.
The care plan tells the CCA what to do when a client experiences a reaction.
Supporting a Client With Diabetes at Mealtimes
Diet plays an important role in diabetes management.
When you prepare meals for an adult or child with diabetes:
- follow the client’s diet plan carefully
- serve meals and snacks on time
- record how much food the client eats at every meal and snack
- refer to the client’s care plan
Calories not consumed at a meal or snack need to be replaced during that day, or the client may experience a reaction. Refer to the client’s care plan.
The care plan also gives directions for what to do when the client experiences a blood sugar reaction.
Nova Scotia CCA Note
Sorrentino’s Canadian Textbook for the Support Worker, 5th Edition focuses this diabetes section on blood sugar, insulin, meals, and reactions. Current Nova Scotia standards add an important personal-care limit: a CCA is not permitted to trim nails for a person with diabetes.
Why this matters in Nova Scotia: For a person with diabetes, nail trimming is outside the CCA’s permitted role under the current Nova Scotia occupational standards.

Hyperthyroidism
An overactive thyroid gland causes hyperthyroidism. The gland produces too much thyroid hormone.
Thyroid hormone regulates body processes. Excess thyroid hormone speeds up all body functions.
Signs and symptoms include:
- weight loss
- increased hunger
- hyperactivity
- palpitations
- nausea
- vomiting
- irritability
- depression
Treatment may involve:
- surgical removal of some or all of the thyroid gland
- one dose of radioactive iodine to destroy some thyroid cells
- medication that inhibits thyroid hormone production
Hypothyroidism
An underactive thyroid gland causes hypothyroidism. The gland produces less thyroid hormone.
Lower thyroid hormone levels slow down all body processes.
Signs and symptoms include:
- weight gain
- impaired memory
- fatigue
- sluggishness
- irritability
- constipation
- slower heart rate
These signs and symptoms contrast with those of hyperthyroidism.
Treatment consists of a thyroid supplement.
Supporting Clients Living With Endocrine Disorders
Lifestyle and eating changes leave some clients feeling frustrated. CCA support includes practical care, respect, and careful communication.
Protect the Client From Infection
Follow infection-prevention directions in the client’s care plan.
- Wear the proper PPE recommended in the care plan.
- Follow Standard Practices at all times.
- Change out of your uniform before leaving the agency or client’s home to reduce the risk of spreading pathogens.
- Observe and perform basic assessments for infection causing breaks in the skin.
- Promptly report these concerns to your supervisor or the correct person.
Nova Scotia CCA Note
Sorrentino uses the broad phrase “basic assessments.” In Nova Scotia, the current standards call the CCA’s ongoing assessment role an observational point of care assessment (POC). The CCA observes the person and care environment, including skin integrity and nutritional intake, and recognizes changes that need to be escalated to a supervisor. A POC observational assessment is not a nursing assessment and does not permit the CCA to complete a comprehensive evaluation for care-planning decisions.
Sorrentino also gives changing out of a uniform before leaving the agency or client’s home as an infection-prevention direction. Current Nova Scotia standards place infection-control practice within the care plan, legislation , employer policies, and workplace procedures. Follow the infection-control and uniform requirements for your workplace.
Why this matters in Nova Scotia: Keep assessment within the CCA’s observational role, escalate changes as directed, and follow current workplace infection-control requirements.
