Diabetes Type 1

What is type 1 diabetes?

From: MedlinePlus, National Library of Medicine

Diabetes means your blood glucose, also called blood sugar, is too high. With type 1 diabetes, your body makes little or no insulin. Insulin is a hormone from your pancreas that helps glucose move from your body into your cells, where it is used for energy. Your body can make glucose, but it also comes from the food you eat. Without insulin, too much glucose stays in your blood.

Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, gums, and teeth.

If your blood glucose gets very high, you can develop diabetic ketoacidosis (DKA). It happens when your body doesn't have enough insulin to allow glucose into your cells. Instead, your liver breaks down fat for energy, which produces ketones. When ketones build up too quickly, they can reach dangerous levels. DKA is a life-threatening emergency.

What causes type 1 diabetes?

From: MedlinePlus, National Library of Medicine

Type 1 diabetes is an autoimmune disease. Your immune system mistakenly attacks the cells in your pancreas that make insulin. Researchers don't yet know exactly why this happens. Genes and environmental factors may play a role in triggering the disease.

Who is more likely to develop type 1 diabetes?

From: MedlinePlus, National Library of Medicine

Type 1 diabetes often begins in children and young adults, but it can appear at any age. Having a parent or sibling with type 1 diabetes may increase your chance of developing it.

What are the symptoms of type 1 diabetes?

From: MedlinePlus, National Library of Medicine

Symptoms often start quickly, especially in children. In adults, they may develop more slowly. Symptoms may include:

• Feeling very thirsty
• Feeling very hungry
• Urinating (peeing) more often, including at night
• Having fatigue
• Having blurry vision
• Losing feeling in your feet, or having tingling in your feet or hands
• Having sores that don't heal
• Losing weight without trying

How is type 1 diabetes diagnosed?

From: MedlinePlus, National Library of Medicine

Blood tests that measure your blood glucose level can show whether it is higher than normal for you.

What are the treatments for type 1 diabetes?

From: MedlinePlus, National Library of Medicine

Type 1 diabetes is a chronic (long-term) condition. You will need daily insulin, either through injections or an insulin pump. Some people also take another diabetes medicine that works with insulin.

Ask your health care provider about the best way to check your blood glucose level and how often you should check it.

Can type 1 diabetes be prevented?

From: MedlinePlus, National Library of Medicine

Type 1 diabetes can't be prevented. But you may be able to prevent or delay health problems related to diabetes by:

• Managing your blood glucose level with finger prick tests or a continuous glucose monitor (CGM)
• Making healthy food choices
• Getting regular exercise

A blood test called the A1C can show how well you are managing your diabetes over time.

Understanding terms used in the source

These definitions explain medical words used above. A definition is not evidence that another condition is present, and it does not predict how a symptom will develop. Ask the clinician which terms apply to the actual examination or test result.

Diabetic ketoacidosis

A type of diabetic metabolic abnormality with an accumulation of ketone bodies.

Fatigue

A subjective feeling of tiredness characterized by a lack of energy and motivation.

Healthy

No history of any serious disease, including the disease being investigated in the proband.

Which doctor should you see?

The suggested department for discussing Diabetes Type 1 is Diabetology, with a endocrinologist / diabetologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• What type of glucose problem has been confirmed?
• What are the individual monitoring and follow-up goals?
• If treatment can cause low glucose, what response plan should be taught?

Treatment discussions and follow-up

Where the source describes treatments, these are an overview of possible care, not a prescription for an individual. Ask which option applies to the confirmed diagnosis, what benefit is expected, what adverse effects to watch for and how progress will be assessed. Availability, approvals and local practice can differ from the country described in the source.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
