Medical Weight Loss in Chicago, IL

Weight loss is not simply a matter of eating less and moving more. For many people, persistent weight struggles are driven by hormonal imbalances, metabolic factors, medication effects, or other underlying health considerations that no amount of willpower can overcome on their own. Medical weight loss at Therahaus Wellness Medspa in South Loop, Chicago takes a clinically informed, whole-person approach to helping you achieve and maintain a healthier weight. We address the root factors that have made weight loss difficult for you specifically and build a plan that is designed for your body, your life, and your long-term success.

Our medical weight loss program is supervised by our clinical team and built around a thorough evaluation of your health, body composition, metabolic function, and personal goals. Depending on your individual needs, your program may include prescription weight loss medications such as GLP-1 receptor agonists, metabolic support, nutritional guidance, and ongoing monitoring to track your progress and adjust your plan as needed. We do not offer one-size-fits-all solutions. Every patient receives a personalized roadmap that reflects their unique physiology and circumstances. Our goal is not just to help you lose weight but to help you build the foundation for lasting health and confidence that extends far beyond the number on the scale.

The Treatment Process

How Our Medical Weight Loss Program Works

Medical weight loss at Therahaus begins with understanding the full picture of your health. Factors including insulin resistance, thyroid function, hormonal balance, cortisol levels, and gut health can all significantly influence the body's ability to lose and maintain weight. By addressing these underlying drivers rather than simply restricting calories, our program supports more effective and sustainable fat loss. For patients who are candidates, prescription medications including GLP-1 receptor agonists such as semaglutide work by regulating appetite signals, slowing gastric emptying, and improving insulin sensitivity, helping the body respond more effectively to a calorie-appropriate diet. Ongoing clinical monitoring ensures your program remains safe, effective, and appropriately adjusted as your body changes.

Step 1: Comprehensive Health Evaluation

Your provider conducts a full health intake including lab work, body composition assessment, review of your weight history, and discussion of your lifestyle, goals, and any previous weight loss attempts to build a complete picture of your needs.

Step 2: Personalized Program Design

Based on your evaluation, your provider designs a customized weight loss plan that may include prescription medication, metabolic support, nutritional recommendations, and lifestyle guidance tailored specifically to your physiology and goals.

Step 3: Program Initiation and Monitoring

Your program begins and regular follow-up appointments are scheduled to monitor your progress, assess your response to any medications, review lab work, and make adjustments to your plan to keep your results moving forward safely.

Step 4: Long-Term Support and Maintenance

As you approach your goal weight, your provider transitions your program toward a maintenance phase that supports you in sustaining your results long-term, addressing any plateaus, and building the habits that keep weight off for good.

Is This Treatment Right for You?

Who Benefits Most from Medical Weight Loss

Medical weight loss is appropriate for adults who have struggled to achieve meaningful, lasting weight loss through diet and exercise alone and want the support of a clinically supervised program. It is particularly well-suited to patients with underlying health factors that have made traditional weight loss approaches ineffective or unsustainable for them.

Ideal for patients who:

  • Have tried multiple diet and exercise approaches without achieving or maintaining the results they want
  • Have a body mass index that qualifies them for medically supervised weight loss treatment or prescription support
  • Suspect that underlying hormonal, metabolic, or medical factors are contributing to their difficulty losing weight
  • Want a structured, science-backed program with professional accountability and clinical monitoring
  • Are committed to making lasting lifestyle changes and want expert guidance to build a sustainable foundation

Supporting Your Results

Medical Weight Loss Aftercare: What to Know

Medical weight loss is a journey that unfolds over months rather than days, and your aftercare is really an ongoing lifestyle practice rather than a post-treatment checklist. Consistency, patience, and open communication with your care team are the most important factors in achieving and sustaining your results. If you are taking prescription medication as part of your program, it is important to follow your dosing schedule precisely and to report any side effects to your provider promptly so your protocol can be adjusted for your comfort and safety.

Do's
Follow your prescribed medication schedule and nutritional guidelines consistently as directed by your provider.
Attend all scheduled monitoring appointments to track your progress and allow for timely protocol adjustments.
Stay physically active at a level appropriate for your current health and fitness as part of your overall weight loss strategy.
Prioritize sleep and stress management, as both have a significant impact on cortisol, appetite regulation, and weight.
Don'ts
Do not skip doses of prescribed medication or adjust your dosing without consulting your provider first.
Avoid highly restrictive or extreme diets alongside your medical program without your provider's guidance, as these can be counterproductive.
Do not become discouraged by slower weeks or plateaus, as these are a normal part of the weight loss process and your team is there to help you through them.
Do not discontinue your program without discussing a transition or maintenance plan with your provider to protect the progress you have made.

Got an amazing hydrofacial with Morgan and my face feels so clean. Everyone was super friendly and helpful. She made sure to care for my sensitive skin and make adjustments based on it.

Dina Andriopolous

What I loved most about Therahaus was that it had such a “family” atmosphere and it was very warm environment. I thought the services were very fairly priced (I received the Hydrafacial), and the location was more than convenient. It’s right off Lake Shore Drive and walkable to Ricobene’s! (IYKYK). Taking the wife next time so she can experience what I did. Will be back no doubt.

Ryne Haberkorn

I was nervous going into my first laser treatment, and the staff immediately made me feel comfortable. They were warm, patient, and explained everything so thoroughly. Definitely a one stop shop as they have all the newest treatments etc. Huge shoutout to Angie! She’s truly the best and made the entire experience so easy. They even offered snacks and a drink… honestly the relaxing day I didn’t know I needed. I’ll 100% be returning.

Kylie Apple

Had an amazing experience with the Therahus team! It was the first time I had IV therapy and can't reccomend it enough. Just what I needed post Bears 2026 season heartbreak :( Also, tried the hydrafacial - did not realize how much I needed it with the winter season. CAN NOT speak highly enoughabout the team. Everyone took great care of me - making me feel comfortable despite it being my first med spa experience. In addition, they were all so knowledgable about all the treatments and this is coming from a med student who just finished his skin block ;) will definitely be visiting in the near future to keep my skin glowing during this winter season!

Joseph Chavez

I had the best and most tailored experience EVER at Therahaus. I got the hydrafacial, IV drip, and lymphatic drainage massage, and it was the most perfect experience ever. Dr. Beltsos made me feel so comfortable and empowered, and I left glowing. I ended up getting the facial membership because it's such a bang for your buck, and I'm so excited to maintain this GLOW. Thank you Dr. Beltsos and team!!! I'm recommending to everyone!!!

Elaine Yoon

I don't have a single negative thing to say about Therahaus. I mean just wow! I haven’t been to this med spa before, so I was a little nervous about what to expect, but Dr. Beltsos and the entire staff were extremely friendly and knowledgeable and immediately put me at ease. They took the time to explain the procedures, the tools and machines they will use and how they work to the care routine afterwards, which made me feel very comfortable. The results were amazing. The location was also very convenient and easy to get to and lots of parking nearby, and the services were very reasonably priced. I’ll definitely be coming back and would highly recommend them.

Raj Mitra

I had an excellent experience at Therahaus Med Spa. The space is modern, calm, and thoughtfully designed, but more importantly, the care is genuinely clinical and professional, not sales-driven. The staff took the time to explain options clearly, answered questions directly, and never pushed unnecessary treatments. What stood out most was the balance between medical rigor and comfort. You feel like you are in capable hands, with practitioners who know what they are doing and take pride in doing it well. Everything from scheduling to follow-up was smooth and well organized. If you are looking for a med spa that prioritizes expertise, transparency, and results over hype, Therahaus is worth your time.

They took the time to answer my questions and checked in throughout my visit.The spa itself was very clean and well-maintained, which made the whole experience even more relaxing. Overall, I highly recommend Therahaus Wellness Spa if you’re looking for excellent service in a clean, peaceful setting. I’m very happy with my Botox results and will definitely be returning!

Demetrius Beasley

I’m genuinely blown away by this place. The fact that it’s owned and actively run by an MD already sets it apart from so many med spas where the physician isn’t closely involved. Dr. Beltsos was incredibly thorough, walking me through every step before and during my BBL and Halo treatments. I felt completely supported the whole way. And Justin, the manager, wasn’t just in the background, he was knowledgeable, engaged, and truly invested in my experience. Top-tier care from start to finish.
