diabetes lifestyle tips for patients
Informed by recognized medical guidance
Overview
Diabetes is a long-term condition that causes your blood sugar (glucose) levels to become too high. Your body either doesn't make enough insulin, or can't use it properly, so sugar builds up in your blood instead of fueling your cells.
Key facts
- It can affect both children and adults.
- Type 2 diabetes is the most common form.
- Type 1 diabetes is an autoimmune condition, meaning the body attacks its own cells.
Yes. More than 1 in 10 adults worldwide have diabetes, and many more are at risk.
Anyone can develop diabetes, but it is more likely as you get older, if you are living with overweight, or if you have a family history. Type 1 usually begins in childhood or young adulthood.
Symptoms
- Difficulty breathing or deep, rapid breathing
- Severe confusion or fainting
- Seizures or convulsions
- Vomiting for more than a few hours
- Blood sugar extremely low or high with these symptoms
- ⚠Vomiting or diarrhoea that stops you from drinking fluids
- ⚠Blood sugar levels that keep rising despite usual care
- ⚠Signs of infection, such as fever or a red hot swollen foot
- ⚠You cannot reach your healthcare team and you feel unwell
Common symptoms
- Feeling very thirsty
- Urinating more often (especially at night)
- Feeling unusually tired
- Blurred vision
- Unexplained weight loss
- Cuts or sores that heal slowly
Symptoms in children
- Sudden weight loss

Symptoms in older adults
- Often no symptoms at all
- Increased thirst and urination

Causes
Main causes
- Type 1: the immune system mistakenly destroys insulin-producing cells in the pancreas
- Type 2: the body becomes less responsive to insulin, or doesn't produce enough
- Gestational diabetes: developed during pregnancy, usually resolving after birth
Risk factors
- Family history of diabetes
- Being overweight, especially around the waist
- Physical inactivity
- High blood pressure
- Being over 40 (or over 25 for some ethnic groups)
When to see a doctor
See a doctor urgently if:
- If you have any diabetes symptoms and also feel very unwell
- If your blood sugar is very high or very low and you feel confused or drowsy
Book a routine appointment if:
- Make an appointment if you have ongoing symptoms like increased thirst, frequent urination, or unexplained tiredness
- If you have a family history and want to get checked
- If you are over 40 and have other risk factors
Diagnosis
Diabetes is diagnosed with a blood test that measures your blood sugar levels. Your doctor may also use a urine test to look for sugar.
Tests that may be done
- HbA1c blood test: gives average blood sugar over the last 2–3 months
- Fasting blood sugar test: after not eating for 8 hours
- Oral glucose tolerance test: blood sugar measured before and 2 hours after a sugary drink
What to expect at your appointment
Your healthcare team will explain the results and what they mean. If you are diagnosed, you won't be left alone — you'll get regular appointments and education.
Treatment
Diabetes is managed with a combination of healthy lifestyle habits, blood sugar monitoring, and — for many people — medication. The goal is to keep your blood sugar in a safe range and prevent long-term damage.
Self-care at home
- Check your blood sugar as often as your team recommends
- Take your medication exactly as prescribed — never stop suddenly
- Eat regular, balanced meals and watch portion sizes
- Aim for at least 30 minutes of moderate activity most days
- Look after your feet daily: wash, dry, and inspect for cuts
- Keep track of your symptoms and tell your team about changes
Medical treatments
Depending on your type of diabetes, treatment may include lifestyle changes, tablets that help lower blood sugar, or insulin therapy. Your doctor will work with you to find the best approach. Never change or stop treatment without speaking to them.
When is surgery considered?
For some people with type 2 diabetes and severe obesity, weight-loss (bariatric) surgery may improve blood sugar control. This is considered only after trying other approaches and is always discussed with a specialist team.
Living with this condition
Living with diabetes is a steady rhythm, not a race. You’ll learn to check your levels, adjust your meals, and listen to your body. Over time, these habits become second nature.
Lifestyle tips
- Keep a ‘sick-day plan’ for infections or illness
- Wear medical ID (a bracelet or card) so people know you have diabetes in an emergency
- Learn to spot low and high blood sugar signs early
- Plan ahead for travel, work, and nights out
- Limit alcohol and sugary drinks
Diet and exercise
A balanced plate is key: fill half with vegetables, a quarter with lean protein, and a quarter with whole grains. Avoid sugary drinks and highly processed snacks. Pair this with regular movement — aim for a brisk 30-minute walk most days, plus two days of strength building (like resistance bands or heavy gardening).
Mental health and emotional wellbeing
Living with diabetes can feel overwhelming. It’s normal to feel anxious, stressed, or ‘burned out’ at times. These emotions matter — talk to your doctor, a counsellor, or a support group. Taking care of your mental health is part of managing your diabetes.
Prevention
Type 1 diabetes cannot be prevented. But type 2 can often be delayed or prevented with healthy eating, regular exercise, and keeping a healthy weight. If you have prediabetes, lifestyle changes can make a big difference.
Vaccines
Infections can hit people with diabetes harder. Keep up to date with flu, pneumococcal, and COVID-19 vaccines — ask your pharmacist or clinic what’s recommended for you.
Screening programmes
If you are over 40, or have risk factors, ask your doctor for a blood sugar test. Regular check-ups for your eyes, kidneys, and feet are also part of good diabetes care.
Complications
If left untreated
- Damage to blood vessels, raising the risk of heart attack or stroke
- Kidney disease that can progress to kidney failure
- Nerve damage causing tingling, numbness, or pain, especially in feet
- Eye damage that may lead to vision loss
- Foot ulcers that, if severe, can lead to amputation
Long-term outlook
Diabetes is a serious condition, but it’s also one you can manage well. With good control and regular care, many people with diabetes live long, active lives. You can keep doing the things you love — you just may need to plan a little more.
