Study Notes
Diabetes Overview
- Diabetes is a chronic disease that occurs when the pancreas doesn't produce enough insulin or the body can't effectively use the insulin it produces.
Insulin and Hyperglycaemia
- Insulin is a hormone that regulates blood sugar levels.
- Hyperglycaemia, or raised blood sugar, is a common effect of uncontrolled diabetes and can lead to serious damage to the body's systems over time.
Symptoms of Diabetes
- Symptoms of diabetes may occur suddenly, but in Type 2 diabetes, they can be mild and take many years to be noticed.
- Symptoms include:
- Feeling very thirsty
- Needing to urinate more often than usual
- Blurred vision
- Feeling tired
- Losing weight unintentionally
Complications of Diabetes
- Uncontrolled diabetes can damage blood vessels in the heart, eyes, kidneys, and nerves over time.
- People with diabetes have a high risk of health problems, including heart attack, stroke, and kidney failure.
- Diabetes can cause permanent vision loss due to damaged blood vessels in the eyes.
- Nerve damage and poor blood flow can cause foot ulcers and potentially lead to amputation.
Type 1 Diabetes
- Type 1 diabetes, previously known as insulin-dependent or juvenile diabetes, requires daily administration of insulin.
- There are approximately 9 million people with type 1 diabetes, mostly in high-income countries.
- The cause of type 1 diabetes is unknown, and there is no known way to prevent it.
Type 2 Diabetes
- Type 2 diabetes affects how the body uses glucose for energy and can lead to high levels of blood sugar if left untreated.
- Over time, type 2 diabetes can cause serious damage to the body, especially to nerves and blood vessels.
- Type 2 diabetes is often preventable, and factors that contribute to developing diabetes include:
- Unhealthy diet
- Physical inactivity
- Obesity
- Family history
- Age
Detecting Diabetes
- The best way to detect diabetes early is to get regular checkups and blood tests with a healthcare provider.
- Diabetes can be mild and may take several years to be noticed, with symptoms similar to other conditions, making early detection crucial.
