Type 1 Diabetes
Often diagnosed in childhood, but you can get it at any age.
Type 1 diabetes is a chronic condition where the body does not produce insulin, a hormone crucial for regulating blood sugar. This happens because the body's immune system attacks and destroys the insulin-producing cells in the pancreas. Without insulin, glucose (sugar) cannot enter the body's cells for energy, leading to high blood sugar levels.
- Frequent urination (Polyuria) - increased glucose in the blood leads to more glucose being passed into the urine, causing more frequent trips to the bathroom, including at night.
- Excessive thirst (Polydipsia) - the body tries to compensate for fluid loss due to frequent urination, leading to increased thirst.
- Extreme tiredness (Fatigue) - without enough insulin, the body cannot properly use glucose for energy, causing fatigue and low energy levels.
- Unintentional weight loss - The body starts breaking down fat and muscle for energy because it cannot use glucose, resulting in weight loss despite increased appetite.
- Blurred vision - high blood sugar can affect the lens of the eye, causing temporary blurry vision.
- Increased hunger - even with increased food intake, the body struggles to convert glucose into energy, leading to persistent hunger.
- Genital itching or thrush - high glucose levels in urine can create an environment for yeast infections, leading to itching and thrush.
- Slow-healing sores or cuts - high blood sugar can impair the body's ability to heal.
- Irritability and mood changes - blood sugar fluctuations can affect mood and energy levels, leading to irritability or mood swings.
If you experience any of these symptoms, please visit your GP.
Insulin injections or pump - individuals with type 1 diabetes require insulin injections or an insulin pump to replace the insulin their body can no longer produce. - Insulin dosage adjustment - insulin doses are adjusted based on blood glucose monitoring, carbohydrate intake, physical activity, and other factors.
- Continuous Glucose Monitoring - a medical technology for people with diabetes to track their blood sugar levels 24/7 without fingerpicks. A small, under-the-skin sensor, a transmitter, and a display device work together to continuously estimate glucose levels in the body's interstitial fluid and wirelessly send the data to a smartphone or reader. CGMs help individuals and their care teams make informed decisions about diet, exercise, and medication, providing real-time data and alerts for high or low glucose levels.
- Blood Sugar Monitoring - using a finger -prick test to measure blood sugar levels before and after a meal
- Regular testing - frequent blood glucose monitoring is crucial to track levels and adjust insulin doses. Regular HbA1c tests (every 3-6 months) provide an average blood glucose level over the past 2-3 months.
- Target range - maintaining blood glucose levels within a target range is essential.
- Healthy Eating - a balanced diet with appropriate carbohydrate intake, along with healthy fats and protein, is important.
- Physical Activity - regular exercise helps improve insulin sensitivity and manage blood sugar levels.
- Weight Management - maintaining a healthy weight is important for overall health and diabetes management.
DAFNE (Dose Adjustment for Normal Eating) is a course for people aged 17+ with type 1 diabetes.
What you’ll learn:
- How to match insulin to the food you eat
- How to manage diabetes in everyday life – holidays, exercise, special occasions, or when you’re unwell
- How to keep blood glucose within healthy targets and reduce long-term risks
- Helps you live as normal a life as possible
- Provides life-long skills and confidence to manage type 1 diabetes
How the course works
- Face-to-face - 5 days in a row or 1 day a week for 5 weeks, plus a follow-up
- Remote - online learning with virtual group sessions
- Small groups (6–8 people), led by trained NHS diabetes nurses and dietitians
To be referred to the DAFNE program, you must have Type 1 diabetes and contact your GP or diabetes team to discuss a referral to a local DAFNE centre. The team will then put you on the right pathway and complete the referral, which typically involves an initial appointment for assessment and preparation.
