In 2019, I had an accident where, the short version is that I have ended up with Osteoarthritis in my right ankle & sub-Talar joints & needed fusion. Pain levels were 5-6/10, chronic and worsening. PTSD & brain-fog affected my well-being, ability to read and work. It was a struggle to walk 400m. Two weeks post gastric sleeve surgery my pain levels were down to 2-3/10 and often negligible & while it was about 3-400m too far, I was able to walk from my favorite café to home (1.8km) with no debilitating pain or consequences. Three weeks post surgery, I had read a novel from cover to cover and started back at work. Lo and behold! I am now almost seven weeks post surgery, I am working productively three days a week (like I used to before the accident), I am looking to spend time with my friends, my PTSD testing results have improved, I am driving locally again and I am walking almost daily around my block (1.2km) with no debilitating pain or consequences. I never dreamt that my world would or could turn around like this so soon. I cannot thank Mo, Maryanne, Haley (EP), Becky (Dietician) & Rod (Psychologist) enough for playing such a pivotal role in helping me to regain my sense of who I am. This holistic approach to major surgery has been an incredible experience & I feel blest that I have had such an incredible, professional & caring team to work with, who enable me to recapture the person in me I thought I had lost. While I have lost significant weight, for me this journey has meant so much more and I look forward to seeing the overall weight-loss progress over the coming year. Now two years down the track and I have finally stabilised and added 5kg. But overall I lost 45kg with the surgery and am extremely happy with the outcome. I cannot thank Mo enough for working with me. Through this surgery, I have improved my health and mobility so much much that when I underwent hindfoot fusion of the subtalar and ankle joints in January 2023, my recovery was near perfect and this week, I was finally able to walk around the lake with a single crutch (2km) during rehab and with no pain repercussions. Last week, I even walked 800+ metres without the crutch - my EP held on to it though. I am so grateful to work with a surgeon and his team who take a wholistic approach and are more focused on a person's overall health and well-being. So incredibly grateful.

BETTER LIFE SURGERY Absolutely outstanding! Mo Atalla is a wonderful surgeon, and his staff are always helpful and kind. They ensured I had a smooth prep, surgery, and follow-up with my procedure (Roux En Y Gastric Bypass). I am so glad I chose Better Life Surgery and would highly recommend them to anyone with no qualms whatsoever. Mo Atalla is incredible. Not only has he taken great care of my health, but also he is lovely to speak with at every appointment, and actually listens to you. It’s rare to find a doctor that combines such personal touches and care for a patient as a person with outstanding quality of medical care. Mo gets it! From his excellent treatment, curiosity, investigative mind and ability to connect, you know where you stand immediately and what next steps look like. Mo is terrific. Knowledgeable, sensitive, informative, I immediately felt at ease and felt confident in receiving expert medical care. Marianne is amazing like a balm for your soul always kind and caring always goes the extra mile guiding and nurturing along the way. I can't thank you enough for the special, excellent care you have provided and for the unique gift you are to your patients. Thank you so much for the great care and surgery you performed on me. I walked away, very impressed with the overall experience. I highly recommend becoming his patient! 10/10 ⭐️⭐️⭐️⭐️⭐️
Highly recommend Mo and the team at BetterLife surgery. Mo and his team of professionals were reassuring, professional and highly supportive from the beginning and throughout the whole process. I appreciate having been referred to Mo for this journey as he is a fantastic and caring surgeon.

When starting this journey I set on my decision and had all my duck in order for it to happen but the nervous and all the other emotions where all consuming until I met Mo, Bec and Marianne . These will be your three biggest supporters. This team truly cares, I had seen other surgeons but never truly aligned goals, expectations and personalities with so find who you are comfortable with. I started out at 118 kg pre op and 6 months post op my weight is 82kg. 36kg down and 16kg away from my goal. My whole self has changed no more anxiety when I leave the house, constantly worried about the people around me looking and laughing. I an no longer constantly hyper aware of my body and how I look etc. I’m now peaceful, happy, comfortable in my own skin and daily movement is no longer a struggle. I would do this process all over again to get my life back and I would go straight to better life surgery team. You’re amazing and look forward to future appointments.
