Have Questions? We’ve Got Answers

GLP-1 medications, such as semaglutide and tirzepatide, are scientifically proven game-changers for weight loss. They mimic natural gut hormones to reduce hunger, cravings, and “food noise,” allowing for effective calorie restriction while targeting the body’s appetite control pathways. At MD Total Wellness in Brea, CA, we use these in a supervised program to help Orange County residents achieve safe, healthy, and lasting weight loss – schedule a free consult to see if our program is right for you.

Unlike telehealth marketing companies, our physician-owned practice in Brea, CA offers personalized, in-person care from board-certified experts with over 20 years of weight loss experience. We provide compounded medications from vetted US pharmacies, same-day starts, customized dosing to minimize side effects, nutrition and lifestyle guidance, and 3D body composition scanning. Our comprehensive approach minimizes side effects (like “Ozempic face” and muscle loss) and helps ensure lasting weight loss success for our Orange County patients—contact us for a free evaluation.

Semaglutide (like Ozempic or Wegovy) targets GLP-1 receptors to curb appetite, leading to about 15% average weight loss. Tirzepatide (like Mounjaro or Zepbound) activates both GLP-1 and GIP receptors for enhanced effects, resulting in around 21% loss and often better tolerance and fewer side effects. Both are low-risk and backed by clinical studies. At our Brea, CA clinic serving Orange County, we’ll help you decide which medication is best for you — book a free consult with Dr. Oliak or PA Mollet to discuss options.

Common side effects include mild nausea, constipation, or fatigue, which are generally temporary and occur when first starting treatment, or increasing medication dosage. Scientific data shows that GLP-1 medications are generally well-tolerated, with serious issues occurring rarely. In our Orange County program at MD Total Wellness in Brea, CA, we use personalized dosing, anti-nausea support, and monthly monitoring and guidance to avoid or minimize side effects.

Clinical trials indicate 15-25% average body weight reduction over 6-12 months, depending on the medication (e.g., more with tirzepatide) and factors like starting weight, lifestyle, and eating habits. Our program will help you to use the medications successfully for safe and lasting weight loss. Our Orange County clients in Brea, CA, and surrounding cities generally see noticeable changes in the first couple weeks. 

Our affordable, pay-as-you-go plans start at $199/month for the first month (starting dose) of semaglutide ($299 ongoing) and $299/month for the first month (starting dose) of tirzepatide ($399 ongoing). Our prices include medication and personalized care from experienced, board-certified providers. Our prices are lower than the brand-name, drug company direct-to-consumer options, and include a full-service program! We accept HSA/FSA. We don’t accept insurance. For Orange County residents, the MD Total Wellness program prioritizes results with transparent and compelling fees. Schedule a free consult today.

Compounded semaglutide and tirzepatide contain the same active ingredients as brand-name versions (e.g., Ozempic or Mounjaro). Benefits of compounded medication include lower price and personalized dosing to minimize side effects and optimize hunger suppression. At MD Total Wellness in Brea, CA, our compounded GLP-1 medications are fully vetted for quality and sourced from licensed U.S. pharmacies—schedule a free consult to learn how this tailored approach can enhance your Orange County weight loss journey.

Most adults with a BMI over 27 qualify, especially if traditional diets haven’t worked. Adults with a BMI <27 may also qualify for treatment to assist with weight maintenance after weight loss or weight loss surgery. At our Brea, CA location in Orange County, we prioritize personalized care – whether your goal is 15lbs or 100lbs of weight loss, or weight maintenance after you’ve lost weight with GLP-1 medication or bariatric surgery. Book a free consult to determine eligibility.

It’s simple: Schedule a free in-office consult at our Brea, CA clinic serving Orange County. Meet Dr. Oliak or PA Mollet for a comprehensive review, then start semaglutide or tirzepatide the same day if suitable. Ongoing support includes monthly follow-up for optimal dosing, nutrition and lifestyle guidance, and body composition tracking. Contact us today to begin your journey toward safe, healthy, and lasting weight loss.
