Semaglutide and Tirzepatide Injections for Weight Loss

Semaglutide and tirzepatide have become important tools in medical weight management, offering a non-surgical option for people working to manage excess weight and obesity. Both have shown significant results in clinical studies, and when prescribed and monitored by a medical team, they can support a meaningful weight loss journey. Dr. Erez Dayan offers medically supervised semaglutide and tirzepatide injection programs at Avance Plastic Surgery Institute in Reno/Tahoe, NV.

Weight-loss medication is a medical treatment that should be carefully evaluated, prescribed, and monitored — and that’s the approach taken at Avance Plastic Surgery Institute. A board-certified plastic and reconstructive surgeon and Medical Director of the practice, Dr. Erez Dayan completed the Harvard Plastic Surgery Program — serving as Chief Resident at Massachusetts General Hospital — before an elite aesthetic fellowship at the Dallas Plastic Surgery Institute, where he was one of only two surgeons selected. Every patient’s progress is closely monitored by the medical team for personalized, supervised care, and Dr. Dayan’s body-contouring expertise allows the practice to support patients through weight loss and, when desired, the refinement that can follow it. These programs are part of the practice’s med spa treatments.

Semaglutide for Weight Loss

Semaglutide is a GLP-1 receptor agonist originally developed to treat type 2 diabetes. By mimicking the GLP-1 hormone — which helps regulate appetite and food intake — it has also proven effective for weight management. Semaglutide works by acting on the areas of the brain responsible for hunger and fullness: activating GLP-1 receptors helps reduce hunger and increase satiety, which can lead to reduced calorie intake and weight loss. In clinical studies, semaglutide has helped patients lose an average of around 15% of their body weight, often alongside other health improvements.

The Benefits of Semaglutide

Meaningful Weight Loss: can support substantial weight loss, which may improve overall health and reduce the risk of obesity-related conditions
Blood Sugar Support: enhances insulin secretion and reduces glucagon release, helping regulate blood sugar
Cardiovascular Health: has been associated in studies with reduced cardiovascular risk in certain patients
Sustained Results: many patients maintain long-term success when treatment is combined with healthy lifestyle changes

Tirzepatide: A Dual-Action Option

Tirzepatide is a dual agonist that combines the actions of two incretin hormones, GLP-1 and GIP. By stimulating both receptors, it not only reduces appetite and food intake but also enhances insulin sensitivity and glucose metabolism, offering a comprehensive approach to weight management and blood sugar control. In clinical trials, tirzepatide has produced weight loss of up to around 20% of body weight in some patients.

The Benefits of Tirzepatide

Substantial Weight Loss: clinical trials have shown weight loss of up to around 20% of body weight in some patients
Metabolic Health: may improve lipid profiles and reduce inflammation, supporting better overall metabolic health
Glycemic Control: targeting both GLP-1 and GIP pathways supports effective blood sugar control
Dual Mechanism: the combination of GLP-1 and GIP activation offers a multifaceted approach to weight management
Sustained Benefits: supports lasting weight loss and metabolic improvements alongside lifestyle changes

These are prescription medications that aren’t appropriate for everyone and carry potential risks as well as benefits. The medical team reviews your health history and overall candidacy before prescribing, and monitors your response throughout treatment, adjusting your plan as needed. The practice provides these medications through proper, regulated channels for quality and consistency.

Supporting Your Results After Weight Loss

Significant weight loss can sometimes leave behind loose skin and stubborn fat deposits. As a skilled plastic surgeon, Dr. Dayan offers a range of body contouring procedures — including tummy tucks, body lifts, and liposuction — to remove excess skin and refine the body after weight loss. The practice also offers advanced skin rejuvenation treatments such as laser therapy, radiofrequency, and microneedling to improve skin elasticity and texture, soften stretch marks, and tighten loose skin for a smoother, firmer appearance.

Hands down the most qualified, honest and knowledgeable plastic surgeon in Northern Nevada. Dr. Dayan and his staff are truly committed to offering leading edge technology, quality and professionalism to each and every treatment ranging from to simple non invasive injections to complicated procedures. What he and his team have to offer always seems too good to be true, but they always over exceed expectations and are incredibly budget conscientious. The Reno-Tahoe area is incredibly fortunate to welcome such a skilled and qualified aesthetic professional into the area!

Dr. Dayan is the surgeon clients should interview with and choose for their procedures. I am always very cautious when deciding important life decisions and I can say without a doubt that I would go through my surgeries again with Dr. Dayan. Every appointment has been professional, courteous, informative, and truthful. I never felt rushed. I also appreciate knowing my privacy is maintained. My fear of pain is very respected, and his demeanor eases it quite a bit. I made my decision to trust Dr. Dayan because of his extensive education, vast experience, and my first-hand witness of his character. These factors have allowed me to look forward to all of my appointments.

I had three consultations and didn't make any decisions lightly, but Dr. Dayan blew the competition out of the water. From the moment I met him during my consultation, he was honest and open while also personable. He also insisted on putting me in touch with previous patients before I made my decision so that I could have a better understanding of the process and recovery as a whole. I ultimately picked him because I knew he would do a good job but also because I felt at ease with him. The day of surgery, I was very nervous and he was comforting while efficient with his time. He was also completely honest with me during my recovery and called either myself or my husband often to make sure I was doing well, but also to make sure my husband understood the process completely. He also makes himself so available for any little questions or concerns I've had, making me feel secure in knowing he's only a phone call or a text away. Although I am not yet completely healed (only 3 weeks post-op) I already feel so confident in the work that has been done. He has helped me to transform something that had me so insecure for such a long time into a body I feel comfortable in. I cannot wait for the final results! I won't hesitate to return to Dr. Dayan for anything else I need done. Between him and his office staff (Alli) I feel like more of a member of the Avance family rather than a patient!

I highly encourage anyone who is considering plastic/reconstruction surgery to schedule a consultation with Dr. Dayan. I couldn't have asked for a better experience and outcome from my breast augmentation. At my consultations, not only did I get my questions thoroughly answered, but I was treated with such genuine kindness and patience. Dr. Dayan is professional, highly knowledgeable, honest and has a certain way of connecting with others. For these reasons, I trusted him and felt supported throughout my whole breast augmentation experience from pre- to post-surgery care. All around, I felt safe and informed about this big decision/investment which is all I could ever ask for. I recovered so much easier than I expected, and my breasts are looking perfect and natural! Dr. Dayan definitely listened to what I wanted and followed through. Lastly, I want to mention how sweet and supportive his team is over at Avance! I am very appreciative of their service.

My results after a "noninvasive" procedure are amazing. The cutting-edge techniques and noninvasive technology that Dr. Dayan incorporates into his procedures, as well as being a gifted and talented surgeon and individual, all contribute to his many accomplishments. However, I personally am impressed with his abilities to listen, communicate, and create beautiful results. I highly recommend a consultation with Dr. Dayan before making a final decision on any kind of procedure. Just another satisfied patient!

I had a perfect experience at Avance. Dr. Dayan was quick, professional, and checked in with me regularly to make sure I was comfortable during the short procedure I needed done. His demeanor was calming and I was able to put full trust in his abilities from start to finish. Erez really knows his stuff, and it's amazing he's here in Reno when he could clearly be somewhere much bigger if he wanted. I definitely won't hesitate to book again if needed.

Absolutely an amazing experience! Where to start? When I first thought of getting a mommy makeover my expectations were not that high because I didn’t ever think I could look the way I wanted to. I always just hoped it would be an improvement and I would be happy with that. Then I met Dr. Dayan. From the first consultation he made me realize that he could give me beautiful results that I didn’t know were possible. He was so kind and confident and I knew from that moment that he was going to be my surgeon. I booked my surgery (a breast augmentation with implants and a tummy tuck with lipo) that day and it was the best choice I have ever made. Before my procedure he was very thorough and explained step by step what he was going to do which made me feel so comfortable. I actually wasn’t nervous at all. I was so excited! I am now 1 month post op and my results are above and beyond what I could have ever dreamed my body could look like after a mommy makeover. Dr. Dayan did an exceptional job. I am not completely healed and I already am so pleased. There are no words that can do justice to how amazing it is to put trust in someone with my body and wake up with results that are better than I could have ever imagined. He truly is skilled in his profession and has the eye for what is best for your body to give you the best results. He followed up with me several times post op to see how I was feeling. If I had any concerns or questions he responded to them quickly and personally which made me feel confident that everything was going well! His care is exceptional from beginning to end. He has an amazing staff as well. His Patient coordinator Ali is so sweet and helpful. She is amazing with communication as well as helping you with financial options and scheduling. You won’t be disappointed working with Dr. Dayan and Ali!

Dr. Dayan and his team are the best of the best! The level of care, professionalism is top of the class. I strongly recommend Dr. Dayan and his entire team. I cannot say enough about his work - he is incredibly talented and I am confident under his care. Of course the results are amazing! I love my LIPS!
