Living Well With Diabetes

Overview

Diabetes is a long-term condition where your body has trouble managing the sugar (glucose) in your blood. Glucose is the main fuel your body uses for energy. A hormone called insulin, made in your pancreas, acts like a key that lets glucose get from your blood into your cells. In diabetes, either your body does not make enough insulin, or the insulin does not work properly. When that happens, glucose builds up in your blood instead of feeding your cells. There are two main types: type 1, where the body stops making insulin and you need insulin every day to stay well, and type 2, where the body makes insulin but it does not work as it should, and over time it may make less. Living well with diabetes is very possible. It means learning a few daily habits, keeping up with check-ups, and getting the right support around you.

Yes, very common. Hundreds of millions of people around the world live with diabetes, and numbers have been rising for decades. In the UK, around 1 in 15 people has diabetes, and many more have blood sugar levels in the 'pre-diabetes' range. If you have it, you are in very large company.

Anyone can develop diabetes, at any age and any body size. Type 1 often starts in childhood or the teenage years but can begin at any age. Type 2 is more common in adults over 40, but is now being diagnosed much more often in younger people. It is more common in people of South Asian, African, Caribbean and Middle Eastern heritage, and in people with a family history of diabetes.

Symptoms

Common symptoms

• Feeling very thirsty, even after drinking
• Needing to pee much more often, especially at night
• Feeling tired, lacking energy, or unusually sleepy
• Blurred vision that comes and goes
• Cuts, grazes or sores that heal slowly
• Losing weight without trying (more typical of type 1)
• Tingling, numbness or a burning feeling in hands or feet
• Getting repeated infections, such as thrush, boils or urine infections
• Feeling hungry more often than usual

Symptoms in children

• Type 1 in children often comes on quickly, over days or a few weeks
• Unusual thirst and drinking far more than normal
• Bedwetting or daytime wetting in a child who was previously dry
• Weight loss despite a good appetite
• Tummy pain, headache, or feeling generally unwell
• Tiredness, mood changes or poor school performance
• Fast, deep breathing, vomiting, or breath that smells fruity or like nail polish remover — this is an emergency
• Type 2 in children can be silent, with no obvious symptoms, and may be found on a routine blood test

Symptoms in older adults

• Symptoms can be vague — tiredness, low energy, or just 'not feeling right'
• Thirst may not be noticed, especially if you already drink little
• Confusion, falls, or a sudden drop in mobility can be the first clue
• Repeated infections, slow-healing skin tears, or mouth problems
• Weight loss that is put down to 'old age' rather than investigated
• Symptoms caused by medicines, such as steroids, can appear quickly

Causes

Main causes

• Type 1 diabetes: the immune system mistakenly attacks the insulin-making cells in the pancreas, so little or no insulin is produced. This is not caused by eating badly or by anything the person did.
• Type 2 diabetes: the body's cells stop responding properly to insulin (insulin resistance), and over years the pancreas cannot keep up with the extra demand.
• Gestational diabetes: diabetes that appears during pregnancy and usually goes away after birth, though it raises the chance of type 2 later in life.
• Other types: damage to the pancreas from illness, surgery or long-term steroid medicines, and some rare inherited forms.
• Body weight, body fat distribution (especially fat around the waist) and physical activity strongly influence the risk of type 2 diabetes.

Risk factors

• Having a parent, brother or sister with diabetes
• Being of South Asian, African, Caribbean, Middle Eastern or other high-risk heritage
• Carrying extra weight, particularly around the middle
• Being physically inactive for long periods
• Increasing age (risk rises from around age 40, or 25 for some higher-risk groups)
• Having had gestational diabetes, or giving birth to a baby over about 4 kg (9 lb)
• High blood pressure or high cholesterol
• Polycystic ovary syndrome (PCOS)
• Long-term use of steroid medicines
• Sleep problems such as heavy snoring or sleep apnoea

When to see a doctor

See a doctor urgently if:

• You have the classic warning signs — intense thirst, peeing constantly, and losing weight — especially if they came on over a few weeks
• You have a foot wound, blister or ulcer that is not healing
• Your blood sugar is repeatedly much higher or lower than usual and you cannot work out why
• You have repeated infections, or an infection with fever that is not settling
• You feel shaky, sweaty, confused or faint and it is happening more often

Book a routine appointment if:

• You have been told you are at risk of diabetes, or have 'pre-diabetes', and want to know what to do next
• You want your annual review, eye check, foot check or kidney check brought forward or explained
• You are struggling with your diet, weight, medication routine, or motivation
• You feel low, anxious, or worn down by managing diabetes
• You are planning a pregnancy, or are pregnant and have diabetes
• You are starting a new job, shift pattern, or exercise plan and want advice on adjusting things

Diagnosis

Diabetes is diagnosed with simple blood tests, usually arranged by your GP or a nurse. A common first test is one that shows your average blood sugar over the past two to three months. If the result is in the diabetes range, a second test on a different day is often used to confirm it. If you are unwell with clear symptoms, one test may be enough. If the doctor thinks you may have type 1, they will arrange tests quickly and you may be referred straight to a specialist diabetes team.

Tests that may be done

• HbA1c blood test — shows your average blood sugar over roughly the last 8 to 12 weeks
• Fasting blood glucose — a blood test taken before you have eaten in the morning
• Random blood glucose — a blood test taken at any time of day
• Oral glucose tolerance test — a sugary drink followed by blood tests, often used in pregnancy
• Urine test for sugar and ketones (ketones are substances your body makes when it burns fat instead of glucose)
• Blood tests that check for the antibodies behind type 1 diabetes, and tests of kidney and liver function and cholesterol
• Blood pressure, weight and waist measurement, and a foot check

What to expect at your appointment

Most people start with a GP or practice nurse appointment and a blood test, with results back within days. If diabetes is confirmed, you will usually be offered an appointment to talk through what it means, what type it is likely to be, and what happens next. You should be offered a structured education course (a set of sessions that teach you how to manage diabetes day to day) and a named contact. Your first year usually includes an eye screening appointment, a foot check, and a review of blood pressure and cholesterol. Ask as many questions as you like — it is a lot to take in at once.

Treatment

Diabetes is managed with a combination of everyday habits, regular monitoring and, for many people, medicines. The aim is to keep your blood sugar, blood pressure and cholesterol in a healthy range, so you feel well now and lower your chance of problems later. Treatment is tailored to you — your type of diabetes, your age, other conditions, and what fits your life. You are in charge day to day, with a team behind you.

Self-care at home

• Take your medicines or insulin exactly as agreed, and ask your pharmacist if you are unsure about timings
• Check your blood sugar as often as your team advises, and write down the results with a note of what you ate or did
• Learn the early signs of a low blood sugar (shaky, sweaty, hungry, dizzy, irritable) and always carry fast-acting sugar with you
• Check your feet every day for cuts, blisters, redness or numbness, and wear well-fitting shoes
• Attend your annual review, eye screening, foot check and dental appointments
• Carry diabetes identification, especially if you take insulin or tablets that can cause low blood sugar
• Keep a 'sick day' plan from your team — illness usually pushes blood sugar up and needs extra attention
• Stop smoking if you smoke; ask for help, as it makes a real difference to your heart and circulation
• Limit alcohol and know how it affects your blood sugar, especially on an empty stomach

Medical treatments

Treatment depends on the type of diabetes and on you. For type 1 diabetes, insulin is essential and is given by injection or through a small pump — your specialist team will teach you how to match insulin to food and activity. For type 2 diabetes, treatment usually starts with support around food, activity and weight, plus a tablet that helps your body use insulin better. Over time, other tablets or injections may be added, and some people eventually need insulin. There are also newer medicines that protect the heart and kidneys, which your team may discuss if they suit you. Alongside this, blood pressure and cholesterol medicines are often prescribed to protect your heart and blood vessels. Your team will review your treatment at least once a year and adjust it as things change. Always ask your GP, nurse or pharmacist before starting, stopping or changing anything.

When is surgery considered?

Surgery is not a standard treatment for diabetes itself. Some people with type 2 diabetes and a high body weight are offered weight-loss (bariatric) surgery through specialist services, and this can greatly improve diabetes — sometimes into remission. It is a big decision with real risks, and it is only suitable for some people, so it is discussed carefully with a specialist team. Separately, people with diabetes may need surgery for other reasons, such as foot problems or heart conditions, and good blood sugar control around an operation helps recovery.

Living with this condition

Day-to-day life with diabetes is mostly a set of small routines: taking your medicines, eating regular meals, moving your body, checking your levels if you have been asked to, and looking after your feet. It also means planning a little — carrying snacks, telling people you are with what to do if you feel unwell, and thinking ahead before exercise, travel or a big event. None of this has to take over your life. Most people find a rhythm within a few months, and the routine becomes background rather than front-of-mind.

Lifestyle tips

• Build activity into your day — walking, gardening, dancing, swimming, cycling; aim for something most days, and start where you are
• Eat regular meals and try to include vegetables, beans, whole grains and lean protein
• Choose water or sugar-free drinks instead of sugary ones
• Get enough sleep — poor sleep makes blood sugar harder to control and increases cravings
• Plan ahead for shift work, travel and illness, and ask your team for advice
• Keep feet protected — check shoes before putting them on, and never walk barefoot where you might cut yourself
• Have a annual flu jab and any other vaccines your team recommends
• Keep a small card or note on your phone with your medicines and emergency contact

Diet and exercise

There is no single 'diabetes diet'. The best way of eating is one you can keep up, that you enjoy, and that keeps your blood sugar steadier. That usually means eating regularly rather than skipping meals, choosing high-fibre carbohydrates (wholegrain bread, oats, lentils, beans), and watching portion sizes of starchy foods. Cutting back on sugary drinks and sweet snacks has a big effect for many people. Some people find a lower-carbohydrate approach helpful; others do well with a Mediterranean-style way of eating — talk it through with your team or a dietitian. For activity, aim for about 150 minutes of moderate movement a week plus some strength work twice a week, spread across the week. Start small and build up. If you take insulin or tablets that can cause low blood sugar, check your levels around exercise and carry a fast-acting sugar with you.

Mental health and emotional wellbeing

Diabetes asks a lot of you, and it is completely normal to feel tired of it, frustrated, worried, or low from time to time. Some people feel 'diabetes burnout' — the point where checking, counting and planning feels like too much. Others feel anxious about low blood sugars, or judged by other people's comments. These feelings are common and treatable, and talking about them is a sign of strength, not weakness. Tell your care team how you are feeling; they can refer you to psychological support or a course. If you ever feel you cannot keep going, or have thoughts of harming yourself, please reach out straight away — contact your local emergency number or a crisis line in your country, or speak to a trusted person who can stay with you. You do not have to cope alone.

Prevention

Type 1 diabetes cannot currently be prevented, and it is not caused by anything you did. Type 2 diabetes can often be delayed or prevented. Large studies show that losing a modest amount of weight, moving more, and eating a balanced diet can cut the risk of type 2 diabetes by well over half in people at high risk. For some people already diagnosed with type 2 diabetes, the same changes can lead to remission — where blood sugar returns to the normal range without medicines. Wherever you are starting from, small, steady changes are worth it.

Vaccines

Diabetes can make infections harder to fight, so vaccinations matter more. In the UK and many other countries, people with diabetes are offered a free flu vaccine each year, and are usually advised to have COVID-19 vaccinations when offered. Ask your GP, nurse or pharmacist which vaccinations are recommended for you, including pneumonia and shingles if you are older. Vaccines do not affect your blood sugar control in a harmful way, though you may need to check your levels more often for a day or two afterwards.

Screening programmes

If you are at higher risk, you can be offered a simple blood test to check for type 2 diabetes or pre-diabetes — often through a GP 'health check' or a national risk tool such as the Diabetes UK risk score, and in England the NHS Health Check. In the UK, the NHS Diabetes Prevention Programme offers a structured lifestyle programme for people found to be at high risk. Once you have diabetes, 'screening' means regular checks: yearly eye screening, annual foot checks, kidney and cholesterol blood tests, and blood pressure checks. These catch problems early, when they are easiest to treat.

Complications

If left untreated

• Damage to the small blood vessels in the eyes (retinopathy), which can affect sight if not picked up early
• Kidney damage (nephropathy) — regular blood and urine tests catch this early
• Nerve damage (neuropathy), causing numbness, tingling or pain, most often in the feet
• Foot ulcers and, rarely, serious foot infections — daily foot checks and good footwear greatly reduce this risk
• Heart attacks and strokes — diabetes raises the risk, which is why blood pressure and cholesterol matter so much
• Gum disease and tooth decay
• Sexual difficulties, such as erection problems
• Mental health difficulties, including anxiety and depression
• In type 1 diabetes, a dangerous build-up of acids called ketoacidosis if insulin is missed or during illness

Long-term outlook

The outlook for people with diabetes today is far better than it was a generation ago. With regular check-ups, good blood pressure and cholesterol control, and care for your eyes and feet, most people avoid serious complications or have them picked up early when they are treatable. Many people with type 2 diabetes reach remission, and many with type 1 live full, active lives with modern insulin and technology. The goal is not a perfect set of numbers — it is steady, kind, consistent care over years, with a team that knows you. That is a realistic and hopeful goal for almost everyone.
