Why these two conditions are often confused
Lipoedema and obesity are often mistaken for one another because both involve excess fat in the body. But the causes, symptoms and treatments are very different. Understanding whether someone has obesity, lipoedema or both matters, because the treatment approach changes completely. Lipoedema is thought to affect up to 1 in 9 women in the UK, yet many go undiagnosed for years.
What is obesity?
Obesity is a chronic condition defined by excessive fat accumulation throughout the body. The World Health Organization classifies obesity as a BMI of 30 or above. It develops through a combination of genetic, environmental and behavioural factors, often influenced by high-calorie diets and low activity levels.
Common symptoms and health risks:
- Excess body weight, usually spread fairly evenly
- Higher risk of heart disease, type 2 diabetes, high blood pressure and certain cancers
- Joint pain and breathing difficulties
How obesity is treated:
- Long-term diet changes and regular exercise
- Behavioural therapy
- Medication when needed
- Weight loss surgery, such as gastric sleeve or gastric bypass, for severe cases
What is lipoedema?
Lipoedema is a chronic fat distribution disorder that affects almost only women. It causes a symmetrical build-up of fat, mainly on the legs and arms, and importantly it is not caused by overall weight gain. It is linked to the female hormone oestrogen and often begins or worsens around times of hormonal change, such as puberty, pregnancy and the menopause. Unlike obesity, lipoedema is usually associated with pain, swelling and sensitivity to pressure.
Lipoedema typically begins in the hips and buttocks, then extends down to the ankles, while the feet stay unaffected. This can create a distinctive column-like shape in the legs. In later stages, it can also affect the arms, though the hands and wrists stay normal.
Common symptoms:
- Symmetrical fat build-up in the legs and arms
- Pain or tenderness when the area is pressed
- Easy bruising
- A feeling of heaviness or tightness
- Symptoms that do not improve much with dieting
How lipoedema is treated:
- Compression therapy
- Manual lymphatic drainage
- Physiotherapy
- Liposuction if conservative treatment is not enough
Why diagnosis matters
The key difference between the two conditions is pain. Obesity fat is usually painless and spread evenly, while lipoedema fat is tender, bruises easily and resists dieting. If losing weight does not reduce your symptoms or change the shape of your legs, lipoedema may be the reason.
The two can also appear together, and in fact most women with lipoedema are also affected by obesity. When both are present, treatment needs to address each one:
- Diet changes, and possibly weight loss surgery, for obesity
- Compression therapy, and possibly liposuction, for lipoedema
If you recognise these symptoms, it is worth speaking to your GP, ideally one familiar with lipoedema. Getting the right diagnosis means you receive the right treatment, avoid years of frustration and finally get the support you need.
