Common reasons adults seek GP advice for diabetes or hormone concerns
People commonly contact a GP when they notice symptoms or results that might be linked to diabetes or hormone change. Reasons include:
Common reasons include:
- increased thirst, passing urine more often or unexplained tiredness
- a new raised HbA1c or fasting glucose result
- questions about starting or adjusting diabetes medicines
- weight gain around the middle or difficulty losing weight
- feeling cold or low in mood with possible underactive thyroid symptoms
- feeling hot, anxious or having palpitations that may suggest overactive thyroid
- menstrual changes, low libido or fertility concerns that may have a hormonal component
- incidental findings on blood tests such as raised prolactin or cortisol
A GP helps interpret results, considers lifestyle, family history and medicines, and advises whether further tests or specialist referral are needed.
Types of diabetes and endocrine topics explained in this section
Below is an overview of the main topics covered. Each has a dedicated article for deeper detail.
Type 2 diabetes and pre diabetes
Type 2 diabetes and pre diabetes are often identified through routine blood tests. Articles describe symptoms, diagnostic thresholds, lifestyle changes, medicines and how early intervention can reduce long term risk.
Type 1 diabetes in primary care
People with type 1 diabetes are usually under a specialist team, although GPs still support sick day advice, infection management and wider health checks. This topic explains how primary care and specialist care work together.
HbA1c and blood tests for diabetes
HbA1c reflects average blood glucose over several months. Content explains how HbA1c is used to diagnose diabetes, monitor control and plan treatment alongside finger prick readings and other tests.
Diabetes reviews, complications and annual checks
Regular reviews help monitor blood pressure, cholesterol, kidney function, eyes and feet. Articles outline what typically happens at an annual diabetes review and why each test matters.
Metabolic health, weight management and cardiovascular risk
Metabolic health links blood sugar, weight, cholesterol and blood pressure. This section explains how lifestyle factors and medical treatment work together to improve long term health, support weight management and reduce cardiovascular risk in people with or without diabetes.
Taking GLP-1 Weight Loss Medications Safely: A GP’s Practical Guide
GLP-1 medications can support weight loss and metabolic health when prescribed safely. This GP written guide explains how they work, what to expect, common side effects and important safety considerations before and during treatment.
Thyroid symptoms and thyroid function tests
Thyroid problems can cause tiredness, weight change, mood changes, heat or cold intolerance and changes in heart rate. Content explains TSH, T4 and T3 blood tests and when treatment or referral is advised.
Tiredness, low energy and possible hormonal causes
Persistent fatigue can have many causes. Articles discuss when hormonal issues such as thyroid disease, adrenal problems or low sex hormones may be considered and which basic tests a GP might arrange.
Raised prolactin or cortisol on blood tests
Occasionally blood tests show raised prolactin or cortisol levels. This topic describes common benign reasons for abnormal results, when repeat testing is needed and when a referral to an endocrinologist is appropriate.

How a GP assesses diabetes and endocrine concerns in practice
A consultation usually combines a symptom review, examination, discussion of lifestyle and medicines and targeted blood tests. GPs look for patterns over time, previous results, family history and other conditions such as blood pressure or cholesterol. Management focuses on clear explanations, realistic lifestyle plans and selecting medicines that suit individual risk and preference.

Linking diabetes and endocrine health to wider wellbeing checks
Blood sugar and hormone balance affect energy, mood, sleep, weight and heart health. Articles in this hub show how diabetes care, thyroid health and metabolic risk fit into a wider wellbeing plan, including diet, movement, mental health and long term screening.
Your GP may discuss:
- relevant blood tests such as HbA1c and thyroid function
- lifestyle measures to prevent or reverse poorly controlled blood sugar
- cardiovascular risk screening and lipid profiles

When to book a GP appointment about diabetes or hormone health
Consider a GP consultation if:
- you have a raised HbA1c or glucose result and are unsure what it means
- you feel more thirsty, tired or are passing urine more often
- you live with diabetes and want help reviewing your control or medicines
- you have symptoms that may relate to thyroid change, such as weight or mood shift
- you have concerns about metabolic health, cholesterol or blood pressure
- you have been told a hormone level is raised and need help understanding the next steps
A private GP can help interpret your results, arrange repeat or additional tests and plan follow up alongside your usual NHS or specialist care.
