Understanding Diabetes: Types, Symptoms, and Management

Diabetes is a group of conditions in which blood glucose becomes too high. This can happen because the body does not produce insulin, does not produce enough insulin or cannot use it effectively. The causes, treatment and monitoring requirements differ according to the type of diabetes.

Because blood glucose is closely connected with nutrition and metabolic health, you may also find our guide to healthy fats, nutrition and metabolism helpful.

Common medical tools used to manage different diabetes types, such as insulin delivery devices, glucose monitoring equipment, and oral medications.

Quick Answer

Diabetes is a group of conditions in which blood glucose becomes too high because the body does not produce enough insulin, cannot use insulin effectively, or both. The principal forms are type 1, type 2 and gestational diabetes.

Symptoms can include thirst, frequent urination, fatigue, blurred vision and unexplained weight loss, although type 2 diabetes may cause no obvious symptoms. Diagnosis requires appropriate blood tests, and treatment depends on the type of diabetes and the individual’s health needs.

Key Takeaways

• Type 1, type 2 and gestational diabetes have different causes and treatment needs.

• Prediabetes increases the risk of type 2 diabetes, but progression is not inevitable.

• Type 2 diabetes is influenced by genetics, health, environmental and lifestyle factors—not simply personal choices.

• Some people with diabetes have few or no noticeable symptoms, so diagnosis requires blood testing.

• Diabetes management may include medication, glucose monitoring, nutrition support, physical activity and regular health checks.

• Supplements and complementary therapies must not replace prescribed diabetes treatment.

• New foot wounds, serious infections or symptoms of a diabetic emergency require prompt medical attention.

What Are the Main Types of Diabetes?

Most people think that there are only two types of diabetes:  type 1 and type 2. However, this is not the case.  There are other types of diabetes that you need to be aware of. Below you will find a breakdown of each one. 

1. Type 1 diabetes is an autoimmune condition in which the immune system destroys the insulin-producing cells in the pancreas. People with type 1 diabetes require insulin treatment to regulate blood glucose. The NHS guide to type 1 diabetes explains its symptoms, diagnosis and treatment.

2. Type 2 diabetes develops when the body does not use insulin effectively and, over time, may not produce enough insulin to maintain blood glucose within a healthy range. Risk is influenced by a combination of genetics, age, ethnicity, body composition, certain health conditions and environmental and lifestyle factors. It should not be presented simply as the result of personal choices. The NHS guide to type 2 diabetes provides information about diagnosis, treatment and ongoing monitoring.

3. Gestational diabetes is high blood glucose that develops during pregnancy, usually because pregnancy-related changes make insulin less effective and the body cannot produce enough additional insulin. Screening, monitoring and treatment help reduce risks for the pregnant person and baby. The NHS guidance on gestational diabetes explains screening, treatment and monitoring during pregnancy.

4. Prediabetes means blood glucose is above the usual range but does not meet the diagnostic threshold for type 2 diabetes. It increases the risk of developing type 2 diabetes and cardiovascular disease, but progression is not inevitable. Individual lifestyle support and, in some cases, medication can reduce risk.

5. Latent Autoimmune Diabetes In Adults (LADA) is a slowly progressing form of autoimmune diabetes diagnosed in adulthood. It is sometimes informally called “type 1.5,” but it is generally considered a form of type 1 diabetes rather than a mixture of type 1 and type 2.

What are the symptoms of diabetes?

Possible symptoms of diabetes include increased thirst, frequent urination, fatigue, blurred vision, recurrent infections, slow-healing wounds and unintentional weight loss. Some people—particularly those with type 2 diabetes—may have few or no noticeable symptoms. A blood test is required for diagnosis.

Over time, diabetes can also lead to nerve damage, known as diabetic neuropathy.

Supplements are sometimes marketed for diabetic neuropathy, but evidence varies and they should not be described as regenerating nerves. Some products can interact with diabetes medication or affect blood glucose. Neuropathy symptoms should be assessed by a healthcare professional before supplements are considered.

Read our evidence-based review of supplements and nerve inflammation in neuropathy, including important safety limitations.

The NHS overview of diabetes explains that symptoms may include thirst, frequent urination, fatigue and unintentional weight loss, although some people with type 2 diabetes have few noticeable symptoms.

Managing Diabetes Safely

If you have possible symptoms of diabetes or believe you may be at increased risk, arrange an appointment with a GP or appropriate healthcare professional for testing. Diabetes cannot be diagnosed from symptoms alone. Urgent help is required when symptoms suggest a diabetic emergency.

Diabetes management depends on the type of diabetes and the individual’s clinical needs. It may include medication or insulin, glucose monitoring, nutrition support, physical activity and regular checks of the eyes, kidneys, feet and cardiovascular health. Follow the personalised plan provided by your diabetes team and do not change medication without professional advice.

Some people with type 2 diabetes may be prescribed GLP-1 medicines. Read our article on GLP-1 dosing and why medical supervision matters.

Diabetes care may involve a GP, diabetes specialist nurse, dietitian, pharmacist, podiatrist, ophthalmology service or endocrinologist. The appropriate professionals depend on the type of diabetes, treatment and risk of complications.

Some people with diabetes also experience leg swelling or circulation problems, but compression socks are not suitable for everyone. Anyone with peripheral arterial disease, reduced sensation, neuropathy, skin damage or a foot wound should obtain clinical advice before using compression garments. Compression products should not replace diabetic foot checks or treatment of the underlying cause of swelling. The NHS guidance on diabetic foot problems explains why wounds, redness, swelling and changes in sensation require prompt attention.

Some people may consider FSA-eligible compression socks after obtaining appropriate clinical advice. Compression is not suitable for everyone with diabetes, particularly where there is peripheral arterial disease, neuropathy, reduced sensation, broken skin or a foot wound.

Diabetes Risk Factors

Diabetes risk factors vary according to the type of diabetes. Having one or more risk factors does not confirm that someone has diabetes, and diagnosis requires appropriate testing.

Type 1 diabetes results from an autoimmune process. Genetic susceptibility and environmental factors may contribute, but there is currently no established way for an individual to prevent type 1 diabetes through lifestyle changes.

The NHS guide to type 1 diabetes explains its symptoms, diagnosis and need for insulin treatment.

Factors associated with a higher risk of type 2 diabetes include family history, increasing age, certain ethnic backgrounds, previous gestational diabetes, PCOS, physical inactivity and overweight or obesity—particularly when weight is carried around the abdomen. Some medicines and medical conditions can also affect blood glucose. Having a risk factor does not mean that diabetes is inevitable.

Women with PCOS may have an increased risk of insulin resistance and type 2 diabetes. Explore our guide to the thyroid–PCOS connection for further context on overlapping endocrine symptoms.

Recognising a Diabetic Emergency

Seek urgent medical help if symptoms include vomiting, abdominal pain, deep or rapid breathing, severe dehydration, confusion, fruity-smelling breath, marked drowsiness or loss of consciousness. These may be signs of diabetic ketoacidosis. Follow the NHS emergency guidance on diabetic ketoacidosis and seek urgent medical help.

How A to Zen Therapies Can Help

At A to Zen Therapies, our complementary therapies are intended to support general relaxation and wellbeing rather than diagnose, treat or control diabetes. A relaxing massage or acupuncture session may help some people manage stress, but neither therapy replaces glucose monitoring, prescribed medication, nutrition support or medical care.

Diabetes can affect sensation, circulation, skin integrity and wound healing. Please disclose your diagnosis, medication, neuropathy, circulation concerns and any recent glucose-related symptoms before booking.

Massage, acupuncture, cupping and heat-based treatments may need to be adapted or postponed where there is reduced sensation, broken skin, infection, unexplained swelling or poor circulation. Where necessary, we may recommend obtaining approval from your diabetes clinician before treatment.

Continue Exploring Diabetes and Metabolic Health

Diabetes management involves more than monitoring glucose. Nutrition, physical activity, weight management, hormone health and emotional wellbeing may all form part of individual care. Explore our Nutrition Hub, Hormone Health Hub, Exercise and Rehabilitation Hub and Mental Wellbeing Hub for evidence-informed guidance on these related topics.

Frequently Asked Questions

What is the difference between type 1 and type 2 diabetes?

Type 1 diabetes is an autoimmune condition in which insulin-producing cells are destroyed, meaning insulin treatment is required. Type 2 diabetes develops when the body becomes less responsive to insulin and may also produce insufficient insulin. Its management varies and may include lifestyle support, medication and insulin.

What are the early symptoms of diabetes?

Possible symptoms include unusual thirst, frequent urination, fatigue, blurred vision, recurrent infections and unexplained weight loss. Type 2 diabetes may develop without obvious symptoms, so testing is important for people at increased risk.

Can diabetes be diagnosed from symptoms?

No. Symptoms can suggest diabetes, but diagnosis requires appropriate blood tests interpreted by a healthcare professional.

Can type 2 diabetes be reversed?

Some people with type 2 diabetes can achieve remission, meaning their blood glucose remains below the diabetes range without glucose-lowering medication for a defined period. Remission is not a cure, and continued monitoring remains important. Diabetes UK’s guidance on type 2 diabetes remission explains that remission is not a cure and continued health checks remain necessary.

Is prediabetes the same as diabetes?

No. Prediabetes means blood glucose is higher than usual but below the diagnostic threshold for diabetes. It indicates increased risk and provides an opportunity to discuss prevention with a healthcare professional.

Can supplements treat diabetic neuropathy?

Supplements should not be presented as a treatment that regenerates damaged nerves. Evidence varies, and products may interact with medication. Pain, tingling, numbness or loss of sensation should be medically assessed.

Is massage safe for someone with diabetes?

It may be appropriate for some people, but treatment should be adapted where there is neuropathy, poor circulation, swelling, broken skin or unstable blood glucose. Medical approval may be advisable, and affected or injured areas should not be treated.

When is diabetes an emergency?

Urgent help is needed for severe drowsiness, confusion, vomiting, abdominal pain, deep or rapid breathing, severe dehydration, fruity-smelling breath or loss of consciousness. People with diabetes should follow their individual emergency and sick-day guidance. These may be signs of diabetic ketoacidosis.
