Dr. Séverine Mazur
"With over 25 years of experience in medicine, including more than 5 years specializing in the management of obesity, I founded the Co-Attitude clinic to devote myself fully to the care of patients suffering from obesity, a disease with multiple repercussions on overall health."
Dr. Séverine Mazur
"I offer attentive support, taking the time to listen and guide you at every step of your health journey. I offer face-to-face services in Montreal as well as telemedicine (videoconferencing) throughout Quebec."
Ms Marcella
"The gastric balloon program is more than just losing weight. It's about learning to look at yourself from the inside so you can feel better about yourself too."
Mr André
"The ball is like a boost to get on track with good lifestyle habits, and the program helps to sustain morale and motivation."
Ms. Céline
"Thanks to my support with the gastric balloon program, I realized that I was hiding behind my weight and dieting to gain control. The balloon enabled me to return to a normal lifestyle. I was able to let go. It feels good."
Mr. Daniel
"Dr Séverine Mazur explained to me scientifically what was going on in my body and my mind in relation to my weight loss and weight regain. She helped me choose the treatment that suited me best. The coaching sessions help me to find my way towards my health goals.
Ms Nadine
"The first meeting with Dr Séverine Mazur opened my mind about obesity. I was able to take the time to tell her what I was thinking. She listened and asked me many questions about my life path. It brought me back to myself. It made me realize that the consultation isn't just about how much weight to lose, but how much I could gain."
Mr Serge
"The Allurion balloon program helped me get started on the road to a balanced diet. During follow-up appointments, the doctor listens a lot and takes my family situation into account, guiding me on: how to eat well in my own way."
Ms Samira
"The first consultation was an eye-opener for me. I realized what I really wanted. It was to be accompanied to feel good in my body and good with the weight my body will accept to have. It gave me new hope."
Ms Hélène
"Dre puts my progress into perspective during follow-up appointments. The coaching questions she asks help me reflect. Dr. Mazur suggested hypnotherapy. It helped me work through different situations that were more difficult to deal with, through relaxation. It feels good to move forward gently."
M. Sophie
"The balloon made it easy for me to cut down on meal portions without feeling hungry. I ate everything. I didn't have to go on a diet. The first few days, you have to get used to the ball and then it settles in. I started walking again at my own pace. During the program, the doctor discussed with me the options I could have to help me if my body wanted to put weight back on. We had a final meeting to recap everything that had been accomplished during the program. She gave me recommendations for monitoring myself in the future. She'll be able to see me again when I need her to. That's reassuring."
