Details and patient eligibility

About

The weight reduction obtained after a first bariatric surgery would improve the vascular (correction of endothelial dysfunction, improvement of arterial wall compliance and evolution of the atherothrombotic process) and microcirculatory function in obese patients with type-2 diabetes.

Enrollment: 37 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• The patient is at least 18 years old and under 70 years old
• The patient is available for a follow-up of 12 months
• The patient signed the consent form
• The patient must be affiliated or beneficiary to an health care plan
• The patient is followed in hospital day care in the endocrine and metabolic disorders department at Nimes University Hospital for a first bariatric surgery

Exclusion criteria

• The subject participates in another interventional study.
• The subject is in an exclusion period determined by a previous study.
• The subject is under the protection of justice, guardianship or curatorship.
• The subject refuses to sign the consent.
• It is not possible to give the subject informed information.
• The patient is pregnant or breastfeeding.
• Subject with known advanced atherothrombotic disease (arterial disease of the lower limbs, significant carotid plaque (generating stenosis> 50%), history of myocardial infarction, stroke)
• The subject is type 1 diabetic.
• The subject has already had a bariatric surgery.
