• Obesity is a disease because it is influenced by lots of factors, and many of them are out of an individual’s control.
• Obesity is a disease because it has the classical signs, symptoms, complications, and etiologies of a chronic disease – a long-lasting condition with persistent effects on individuals’ health.

Given its classification as a chronic disease, obesity treatment should be approached with care. People with obesity should seek medical care and ask their healthcare professional about treatment options.  On the other side, sceptics believe a whole range of myths about obesity. They argue:

• Obesity is a lifestyle choice and a result of how much you eat and how little you move.
• Saying obesity is a disease allows people to make excuses and not be responsible for their actions. 

This type of misinformation and stigma impacts the way society thinks about obesity and impairs how it should be treated.

In January 2019, the Royal College of Physicians (RCP) recognised obesity as a disease. A chronic yet manageable disease that’s affected not only by our genes but also by the modern environment we live in. According to Dr. Andrew Goddard, “It is not a lifestyle choice caused by individual greed, but a disease caused by health inequalities, genetic influences, and social factors.” Even with this recognition, the debate around why obesity is a disease continued and reactions in the UK media were strong.

Around the world, similar expert working groups have arrived at the same conclusion that often provokes heated debates in the media. Despite ongoing debate, is obesity a disease? Many in Ireland now recognise it as such, countering the misconception that it's merely a lifestyle choice – influenced by how much you eat and how little you move. In truth, most people living with obesity have many reasons for their weight. Obesity fact - the science is clear that obesity is not just a result of poor choices.

In fact, obesity is a disease that:

• Puts people at a high risk of developing or worsening other serious health conditions such as cardiovascular disease, type 2 diabetes, increased blood pressure, high cholesterol, obstructive sleep apnoea, certain types of cancer, anxiety, and depression.
• Changes the way the body responds to treatments. What worked before may not work anymore.
• Is constantly made stronger by our everyday environment.
• Affects people for life.

Though obesity is a disease with serious health implications, people living with obesity rarely seek professional medical help and believe they should deal with it on their own. 

Thankfully, more and more healthcare professionals recognise the complexity of obesity and are learning how to help. Their toolbox of treatment options is also growing and is constantly being updated. Today, obesity is a disease with treatment options that include behavioural therapy, individualised nutrition therapy, weight-loss medication, and bariatric surgery. Modern obesity management looks beyond what you eat and how much you move. It involves understanding individual eating patterns (how, when, and why you eat), as well as patterns of mood, sleep, stress, and physical activity. A personalised treatment plan will probably require a combination of different treatment options to meet your needs.

Excess weight is not the only reason why obesity is a disease. Stigma, shame and low self-esteem are the consequences we don’t see and ones that impact people living with obesity on a daily basis. 

While misinformation and stigma continue to impact society’s understanding of obesity, more healthcare professionals beginning to recognise as a chronic disease – one that demands medical attention and potentially treatment.

The good news is that obesity is a disease that is manageable and even minor modifications can improve your overall health and wellbeing.  Weight loss of only five percent is enough to lower the risk of many weight-related health complications, including diabetes, cardiovascular disease and more.

Currently, there are several treatment options available for managing overweight and obesity. To lose weight and keep it off in a healthy way, it is important to acknowledge that obesity is a chronic disease.
