Obesity in Spain

Economic impact
In Spain, the current cost to the National Healthcare System caused by obesity-related health problems is already €2,000 millioni. If the trend continues, by 2030 there will be more than 27 million overweight people in Spain, which will mean an extra cost of €3,000 millionii. This makes it essential that the responsible administrations act to curb an unsustainable situation for patients themselves and for the system.
Currently in Spain there are no reimbursed drugs for obesity while there are more than 11,000 patients on the waiting list for bariatric surgeryiii. People with obesity have health complications, leading to additional costs due to the treatment needed for up to 236 comorbidities or pathologies associated with obesityiv. In Europe, people with obesity incur 20% more healthcare costs and 68% treatment costs than people who do not have the diseasev,vi.

Societal impact
In Spain, obesity is recognised as a disease and is included in the National Health System (SNS) Portfolio of Servicesvii. However, there is no active policy on specialised centres for the diagnosis and treatment of obesity. Due to the lack of an effective national response, 22% or more of adults suffer from obesityviii, a figure that doubles when we talk about the rate of overweightix. With children and adolescents, the most conclusive studies indicate that between 15% and 18% have obesityx.

Individual impact
Obesity is a chronic disease which is not recognized, often even by those affectedxi. It presents a large number of comorbidities and associated pathologies. Between 2014 and 2017 there was a 14,37% increase in diabetes diagnosesxii, which might be related to the increase in cases of obesity and overweight. Obesity is the number one cause of type 2 diabetes mellitus, and the rate of diabetes in adults is currently 13,8% of the populationxiii,xiv. In addition, diseases associated with obesity include dyslipidemia, hypertension, fatty liver, obstructive sleep apnea syndrome (OSAS), infertility, some of the most prevalent tumours such as breast cancer, and a large proportion of heart disease and strokesxv,xvi.

Clinical challenges
Obesity is seen as the patient’s individual responsibility due to the lack of training, information and system involvement, which also affects the current clinical practicexvii. This lack of training and up-to-date information prevents professionals from providing appropriate diagnosis and treatment to their patientsxviii. For these reasons, an integrated, unbiased approach is needed to communicate with patients about different treatment options. The creation of multidisciplinary teams is necessary, with Primary Care to diagnose patients early, establish appropriate treatments and, if necessary, refer the patient to specialist care.


About OPEN Spain

OPEN aims to build national support for improving obesity care through a partnership between public health policy makers, patients, scientific societies and experts in the field of obesity. The core focuses of OPEN Spain include:

Recognition of obesity as a chronic and prevalent disease
The recognition of obesity as a chronic and prevalent disease is essential in order to develop policies that will address the obesity epidemic. Without this recognition it will continue to grow, and the economic costs will continue to increase, affecting the sustainability of healthcare and placing an unprecedented burden on both the National Healthcare System and society in general.

Collaboration with the OPEN Network
Collaboration with the different members of the global OPEN network in order to share global resources, discuss the progress in our countries, exchange learning with other experts, and develop tangible tools to help meet our shared goals.

Design of multidisciplinary therapeutic strategies
Bringing together expertise (medical, surgical, psychological, etc.), to combat the current obesity epidemic by developing specialised centres for the correct diagnosis and treatment of obesity.

Key Achievements

Although OPEN Spain is relatively new, we have already accomplished important milestones:

  • Development of an OPEN Spain Position Paper: after several digital and face-to-face meetings, a position paper was developed reflecting the current Spanish situation, its positioning and recommendations for progress.
  • COVID-19’s impact on people with obesity: due to the impact of COVID-19 on people with obesity, OPEN Spain is planning to address and reinforce this evidence to health authorities, warning them from the increased risk that people with obesity have shownxix and the consequences that the lock down has had (approximately +3kg on average, as seen in a national survey developed by SEEDO and SEENxx) and asking for solutions. In addition, bariatric surgeries have been postponed and weight increases have been seen.

Priorities in 2020 and Beyond

The year 2020 has not progressed as expected due to COVID-19. Despite this, OPEN Spain remains committed to its mission and remit:

  • Increasing awareness of obesity among politicians, healthcare professionals and society in general.
  • Developing initiatives which lead to better obesity management, for instance encouraging the coordination of multidisciplinary teams for diagnosis and treatment of the disease.
    Maintaining collaboration within the international OPEN network in order to achieve global objectives and share national experiences.
