Type 1 diabetes in primary care
Type 1 diabetes is an autoimmune condition in which the body stops producing insulin. It often develops in childhood or young adulthood, but it can occur at any age. People with type 1 diabetes require lifelong insulin treatment.
Although specialist diabetes teams lead long-term management, general practice plays an important role in early recognition, shared care, routine monitoring and support for people living with type 1 diabetes.
This page explains how type 1 diabetes presents, how GPs are involved in ongoing care, and when urgent assessment is required.
These articles are intended as educational sources, not diagnostic nor taking place of a proper medical assessment. If you need help, please book an appointment with one of our GP’s.
What is type 1 diabetes?
Type 1 diabetes occurs when the immune system destroys the insulin-producing cells in the pancreas. Without insulin, blood glucose levels rise quickly and can become dangerous.
Key features:
- Autoimmune condition
- Not caused by lifestyle factors
- Requires insulin from diagnosis
- Can develop at any age
This is different from type 2 diabetes, which is primarily related to insulin resistance.
How type 1 diabetes commonly presents
Symptoms often develop over days or weeks and may include:
- Excessive thirst
- Frequent urination
- Weight loss
- Fatigue
- Blurred vision
In some cases, people present acutely unwell with diabetic ketoacidosis (DKA), which is a medical emergency.
Type 1 diabetes and diagnosis
Diagnosis is usually made urgently using blood glucose testing and supported by further specialist assessment.
GPs play a key role in:
- Recognising symptoms early
- Arranging urgent referral when type 1 diabetes is suspected
- Supporting patients before and after diagnosis
Type 1 diabetes should always be considered in people with rapid onset symptoms, particularly if weight loss is present.
The role of primary care in type 1 diabetes
Diagnosis is usually made urgently using blood glucose testing and supported by further specialist assessment.
GPs play a key role in:
- Recognising symptoms early
- Arranging urgent referral when type 1 diabetes is suspected
- Supporting patients before and after diagnosis
Type 1 diabetes should always be considered in people with rapid onset symptoms, particularly if weight loss is present.
The role of primary care in type 1 diabetes
While specialist teams oversee insulin management, GPs support people with type 1 diabetes through:
- Ongoing medical care for other conditions
- Medication reviews
- Monitoring blood pressure and cholesterol
- Managing intercurrent illness
- Mental health support
- Coordination of care between services
Primary care provides continuity alongside specialist input.
Monitoring and routine checks
People with type 1 diabetes are usually offered regular reviews that may include:
- HbA1c monitoring
- Blood pressure checks
- Cholesterol testing
- Kidney function tests
- Foot and eye screening
These checks help reduce long-term complications.
Type 1 diabetes and illness
Intercurrent illness can significantly affect blood glucose control.
During illness:
- Blood glucose may rise unpredictably
- Insulin requirements may change
- Risk of dehydration increases
GPs can provide advice on sick-day rules and when urgent review is needed.
Mental wellbeing and type 1 diabetes
Living with type 1 diabetes requires constant attention and can affect mental health.
People may experience:
- Diabetes distress
- Anxiety around glucose control
- Burnout from long-term self-management
Primary care plays an important role in recognising and supporting mental wellbeing alongside physical health.
When to seek urgent medical help
Seek urgent help if someone with type 1 diabetes experiences:
- Persistent vomiting
- Severe abdominal pain
- Rapid breathing
- Confusion or drowsiness
- Very high blood glucose with ketones
- Signs of dehydration
These may indicate diabetic ketoacidosis and require emergency assessment.

When to speak to a GP
You should seek GP review if:
- You are struggling with diabetes management alongside other health issues
- Illness is affecting glucose control
- You have concerns about medications or monitoring
- You feel overwhelmed or burnt out risks
Support is appropriate at any stage.

GP insight
In primary care, type 1 diabetes is managed through partnership with specialist teams. GPs focus on whole-person care, early recognition of problems, and supporting people to live well with a demanding long-term condition.
