Overview
Obesity is a medical condition in which a person has too much body fat. It can affect how the body works and increases the risk of many other health problems, often called complications.
Key facts
- Obesity is a chronic (long-term) condition, not a personal failing.
- Having obesity can raise the risk of heart disease, diabetes, and joint problems.
- Losing even a small amount of weight can lower the risk of these complications.
Yes. Obesity is very common around the world. In many countries, it affects more than 1 in 4 adults.

When to see a doctor
See a doctor urgently if:
- See a doctor the same day if you have new chest pain, shortness of breath, or a swollen, painful leg.
- Do not wait if your blood pressure is very high at home or if you feel faint.
Book a routine appointment if:
- Make a routine appointment if you have obesity and have not had a health check in the past year.
- Talk to your doctor about any new symptoms like tiredness, joint pain, or snoring.
Diagnosis
To diagnose obesity, a doctor may measure your height and weight to calculate your body mass index (BMI). They will also look at your waist size and ask about your health history. To find complications, they may check your blood pressure, blood sugar, and cholesterol.
Tests that may be done
- Body mass index (BMI) and waist measurement
- Blood pressure check
- Blood tests for sugar, cholesterol, and liver function
- A sleep study if you have symptoms of sleep apnea
- Imaging tests, such as an ultrasound of the liver, if fatty liver disease is suspected
What to expect at your appointment
Your doctor will talk with you about your symptoms and may order some tests. The goal is to understand your overall health and work out a plan together. You may be referred to a dietitian or a specialist in weight management.
Treatment
Treating obesity is not about quick fixes. It is about improving your health step by step. For many people, a combination of healthy eating, physical activity, and support can reduce the risk of complications.
Self-care at home
- Eat more vegetables, fruits, whole grains, and lean proteins.
- Limit sugary drinks, processed snacks, and large portions.
- Aim for at least 30 minutes of moderate activity most days, such as walking or swimming.
- Try to get 7–9 hours of sleep each night.
- Find ways to reduce stress, like breathing exercises or a relaxing hobby.
Medical treatments
Doctors can prescribe treatments to help with weight loss or to control conditions caused by obesity, such as high blood pressure or diabetes. These are always used together with lifestyle changes. For some people, there are also non-surgical procedures, such as a gastric balloon, which are done at a hospital.
When is surgery considered?
Weight-loss (bariatric) surgery may be an option for people with severe obesity or for those who have not had enough improvement with other treatments. Surgery helps you eat less and absorb fewer calories. It is a major decision and requires a full evaluation by a specialist team.
Living with this condition
Living with obesity means managing your health every day. Small, steady changes in what you eat and how you move can make a big difference over time.
Lifestyle tips
- Plan your meals ahead so it is easier to make healthy choices.
- Move your body in ways that feel okay for you, even if it is only a few minutes at a time.
- Sit less during the day – take short breaks from sitting at work or at home.
- Keep a diary of your meals, exercise, and mood to spot patterns.
- Stay in touch with your healthcare team so they can help you stay on track.
Diet and exercise
Aim for a balanced diet with colorful vegetables, fruits, lean proteins, and whole grains. For exercise, start slowly and build up gradually. Even gentle activity, like walking or chair stretches, can help your heart, blood sugar, and joints.
Mental health and emotional wellbeing
Obesity can affect how you feel about yourself and how you cope with stress. It is very common to feel sad, anxious, or alone. Speaking to a counsellor or a trusted friend can help. If you are in crisis, please reach out to your local mental health emergency services.
Prevention
Obesity complications can often be prevented or delayed by keeping a healthy weight, staying active, and getting regular health checks. Even a 5–10% weight loss can lower the risk of heart disease and diabetes.
Screening programmes
If you have obesity, regular check-ups can catch early signs of complications, such as high blood pressure, diabetes, or high cholesterol. Early detection means earlier treatment and a better chance of preventing more serious problems.
Complications
If left untreated
- Type 2 diabetes and high blood sugar
- Heart disease and heart attacks
- Stroke
- High blood pressure
- Fatty liver disease and liver damage
- Kidney disease
- Sleep apnea and breathing problems
- Osteoarthritis and joint pain
- Mental health conditions, such as depression and anxiety
- Some types of cancer, including breast, bowel, and womb cancer
Long-term outlook
Having obesity does not mean these complications will definitely happen. Many people improve their health significantly with the right support. Focus on one small change at a time and celebrate every step forward. There is always hope for better health.
