What is diabetes?
Diabetes is a medical condition where people cannot produce enough insulin, or their body cannot adequately use the insulin it has produced. Insulin is the hormone that controls the level of glucose, which is a form of sugar, in the bloodstream by regulating its movement into your cells. Insulin is necessary because glucose is a main source of energy for the body's cells. The human body can produce glucose or get it from food.
There are three types of diabetes:
- context Type 1 diabetes is an autoimmune disease where the pancreas does not produce insulin. Type 1 diabetes is not preventable. Persons living with type 1 diabetes require insulin.
- context Type 2 diabetes develops when the pancreas stops producing enough insulin or when the body stops effectively using the insulin that is produced. Many people with type 2 diabetes can manage the condition with diet and exercise, while others may also need to take medications.
- context Gestational diabetes develops when a woman's body stops adequately producing or using insulin while she is pregnant. Affecting 2%-4% of all pregnancies, this form of diabetes usually goes away once the baby is born. However, mother and child remain at a higher risk of developing type 2 diabetes later in life.
What are the complications or effects of diabetes?
When the pancreas does not produce insulin, glucose builds up in your blood. This condition is known as hyperglycemia. Fluctuations of blood glucose levels outside of the target range can lead to serious health problems involving the blood vessels and nerves, including heart disease, stroke, kidney failure, heart attack, and blindness.
When the body does not have glucose for fuel, it starts to use fat. As a result of that process, the cells produce ketones that are then released into the blood. Some of these ketones will pass out of the body through the urine. However, high levels of ketones in the blood can cause the blood to become acidic. In people with diabetes, this is called diabetic ketoacidosis or DKA. DKA can lead to coma or death if not treated. DKA is more common in those with type 1 diabetes but can also happen to those with type 2 diabetes.
Hypoglycemia can also occur. Hypoglycemia is too little glucose in the blood. It can occur when insulin removes too much glucose from the blood as a result of increased physical activity, too much medication, too little food (or a missed or delayed snack or meal), and the effects of drinking alcohol.
Long term Complications
Other impacts of diabetes will happen gradually. The risk of these complications increases the longer someone has diabetes and the less controlled their blood sugar is. Complications include:
- context Cardiovascular disease, including high blood pressure, cholesterol issues and other heart issues
- context Nerve damage (neuropathy)
- context Kidney damage (nephropathy)
- context Eye damage (retinopathy) and other vision conditions, such as cataracts and glaucoma
- context Nerve damage in feet, legs, and hands due to poor circulation
- context Infections due to cuts and blisters
- context Skin conditions, including bacterial and fungal infections
- context Hearing impairment
- context Alzheimer's disease and dementia
- context Depression
What are the symptoms of diabetes?
Symptoms or signs linked to the development of diabetes include:
Not all people will show signs and symptoms.
- context Unusual or increased thirst
- context Frequent need to urinate
- context Blurry vision
- context Extreme hunger
- context Frequent or recurring infections
- context Unexplained weight loss or weight gain
- context Fatigue or lack of energy
- context Irritability
- context Disorientation
- context Slow-healing cuts or sores
- context Tingling or numbness in the hands or feet
Can occupational factors affect diabetes?
Workers with diabetes may be affected by the following occupational factors:
- context Working in temperature extremes
- context Heavy level of physical activity
- context Schedules that include shift work or inadequate time to rest between shifts
- context Difficulty finding time to take medications or eat regularly
What else can workplaces do?
Be aware of the risk factors that can be controlled. Workplaces can help by:
- context Including diabetes prevention and management information in any workplace health or wellness program.
- context Educating management and supervisors about diabetes so that they are aware of the needs of workers with diabetes and how best to accommodate them.
- context Asking workers with diabetes what accommodations they think would best suit them. Not all people with diabetes will need the same accommodations. Some may need a private area to test their blood sugar levels or to administer insulin injections while others may not.
- context Changing a worker's work schedule, if necessary.
- context Workers with diabetic retinopathy, which is a vision disorder caused by diabetes, may need to use assistive technology to help them see.
- context Workers with diabetic neuropathy, which is a nerve disorder caused by diabetes, may need to use a chair or stool while they work.
- context Making sure first aiders are trained to recognize common acute symptoms of hypoglycaemia and related issues so they can provide assistance.
- context Providing workers a place to rest until their blood sugar levels become normal.
- context Providing “sharps” disposal if insulin is administered with needles.
- context Allowing workers to keep food and testing supplies near their workstations or break area.
- context Allowing time for medical treatment and recuperation, as well as any educational sessions necessary to learn about their condition and how to manage it.
- context Providing workers with breaks to eat or drink, take medication, or test blood sugar levels.
- context Encouraging physical activity (e.g., time, equipment, walking paths, etc.).
- context Providing healthy food choices in cafeterias, vending machines, meetings, etc.
- context Providing access to smoking cessation programs.
- context Addressing both organizational factors and mental health factors to help reduce stress.
- context Providing access to employee assistance programs, support groups, etc.
What should a workplace do if a person has hypoglycemia?
Hypoglycemia should be treated by first aid. Symptoms of hypoglycemia include cold, clammy or sweaty skin, blurred vision, dizziness, shakiness/lack of coordination, headache, irritability or hostility, stomach ache, or nausea.
If possible, check the person's blood glucose level. If a glucose meter is not available, treat the symptoms. It is better to be safe. First aid steps for a conscious individual include to:
If the treatment does not work, or if the person becomes confused or disoriented, loses consciousness, or has a seizure, call 911 immediately for medical help.
- context Have the individual drink or eat a fast-acting carbohydrate, such as 15 mg of glucose from a glucose tablet, 15 ml (3 teaspoons) or 3 packets of table sugar dissolved in water, 175 ml (3/4 cup) of juice or a regular soft drink, 6 candies (e.g., hard candies like LifeSavers®, or jellybeans), or 15 ml (1 tablespoon) of honey.
- context Wait 10 to 15 minutes and recheck their blood glucose.
- context If your energy level is still low, treat again. If the next meal is more than one hour away, have a snack (half a sandwich or cheese and crackers).
