Weight loss is never easy, but it shouldn’t be impossible. For some, a proper diet and exercise routine helps them slim down. For others, factors like genetics and hormones work against them, placing additional obstacles in their path to success. Given the biological challenges, is long-term weight loss a realistic goal?
At Marcos Medical, it is!
Our weight loss clinic looks at the underlying factors of your struggles and addresses them through personalized plans. Our range of weight loss therapies helps you lose weight and develop better lifestyle habits so that you can sustain your results and enhance your overall, everyday well-being.
When you’re struggling with factors outside of your control, we offer weight loss injections in San Antonio. Working alongside the body’s natural processes, these powerful medications have helped thousands of people reach their weight loss goals.
GLP-1 Medications: Neither a Quick Fix nor a Miracle Drug
When something is successful for so many people, it’s easy to dismiss it as a “quick fix” or a “miracle drug.” But as we stated before, weight loss is never that easy. Weight loss injections are tools to help you reach your goals, but they do not deserve all the credit.
Our weight loss injections, also known as glucagon-like peptide-1 (GLP-1) medications, complement traditional weight loss strategies like maintaining a balanced diet and getting regular exercise. They work internally to address biological factors that conventional methods alone cannot modify, promoting sustainable and healthier lifestyle choices.
What are GLP-1 medications?
We offer 2 GLP-1 injections: semaglutide and tirzepatide. Although the medications work similarly, one might prove to be a better option for you.
GLP-1 medications mimic the glucagon-like peptide-1 (GLP-1) hormone, which your body produces after you’ve eaten to signal fullness. Semaglutide and tirzepatide aid in weight loss by replicating this hormone, essentially “tricking” your brain into thinking you’re satisfied with smaller meal portions.
Weight loss injections in San Antonio help you maintain a calorie deficit—burning more calories than you consume—which is essential for weight loss. Additionally, they reduce cravings by slowing digestion, extending satiety and making it easier to manage your appetite.
Lastly, semaglutide and tirzepatide regulate blood sugar levels by promoting insulin production. In fact, before researchers recognized their powerful weight loss capabilities, these medications originally treated individuals with type 2 diabetes. Better blood sugar control helps your body efficiently use food and nutrients for energy instead of storing them as fat.

So, what’s the difference between semaglutide and tirzepatide?
The difference lies in tirzepatide’s ability to mimic the GLP-1 hormone and the glucose-dependent insulinotropic polypeptide (GIP) hormone. GIP further supports blood sugar regulation and the feeling of fullness. Although this medication may be stronger, that doesn’t necessarily mean it’s better. Both semaglutide and tirzepatide have proven to help people lose up to 15 to 20% of their body weight.
Who is a good candidate for weight loss injections?
Usually, weight loss injections can help most individuals who struggle with obesity or have health issues due to excess weight. If you have a body mass index (BMI) of 30 or more and previous weight loss efforts haven’t worked, weight loss injections may be right for you.
Who is not a candidate for weight loss injections?
At Marcos Medical, safety is our top priority. Individuals with the following health concerns shouldn’t use weight loss injections in San Antonio:
- Type 1 diabetes
- Personal or family history of medullary thyroid carcinoma
- History of pancreatitis
- Gallbladder disease
- History of gastroparesis
In addition to the above health concerns, other factors might make you an unsuitable candidate for weight loss injections:
- Pregnant or breastfeeding
- Under the age of 18
- BMI under 25
If you fall under these categories, don’t lose hope! You can still work with our providers to develop a weight loss program that’s safe and effective for you. We can discuss all of this during your consultation.
Consultation
To help you lose weight, we give in-depth consultations to identify the root causes of your concerns and suggest the right plan for you. This starts with a medical assessment where we talk about your goals, medical history, and previous weight loss attempts. After the discussion, we follow these 4 steps:
Order Extensive Lab Work
Laboratory tests aid in understanding your metabolism (the bodily process of converting food into energy). Our thorough metabolic panel assesses these different aspects:
- Blood sugar levels
- Kidney function
- Nutrient balance
- Thyroid function
- Hormone levels
These results give us insight into your overall health and help us determine if weight loss injections in San Antonio are right for you.
Styku 3D Body Scanner
In 30 to 40 seconds, this noninvasive device performs a full-body rotation and assesses your unique shape and body composition.

With this data and the lab tests, we tailor your weight loss program to you and track your progress throughout your journey.
Personalize Your Plan
With Marcos Medical, weight loss is a collaborative process; we work together to achieve your goals. This means choosing the right medication for you, and also offering nutritional counseling and physical activity recommendations.
Treatment Details
Now that we’ve determined the best weight loss program for you, we prepare you for the journey ahead. For semaglutide and tirzepatide, we teach you how to self-administer your injections. The benefit of GLP-1 medications is that they don’t require daily doses or even coming back into our office!
On the same day each week, you will administer your weight loss injection in rotating areas of your body, including:
- Upper arm
- Abdomen
- Thigh
And that’s it! You’ll dispose of the used injection accordingly and store future doses in the refrigerator.
Ongoing Treatment at Marcos Medical
We don’t just teach you how to administer your weight loss injections in San Antonio, and then leave you to fend for yourself! Our medical weight loss program involves expert medical supervision throughout your journey. For that reason, we schedule regular check-ins to keep track of your weight loss with our body scanner, which updates us on your body composition and caloric needs. Based on your progress and comfort level with the medication, we can adjust your dosage if necessary.
How long will I stay on weight loss medications?
The duration of your treatment depends entirely on you and your progress. Standard care begins with 3 months of GLP-1 injections, with dosage adjustments and monitoring via regular check-ins. However, we may extend the duration of treatment with GLP-1 medications depending on your individual needs and goals.
What happens when I want to discontinue medication?
Your comfort level and how confident you feel in maintaining healthy habits determine when to stop medication. If you’ve been taking low doses of weight loss medications, you can stop immediately. Patients taking larger doses may require a gradual reduction to give their body time to adjust. We can discuss all of this during your regular check-ins.
When will I see results?
Some people notice results in as little as 4 weeks. Before you see the results, you will feel them. Following the first injection, expect less hunger and a suppressed appetite. Use this as encouragement that your weight loss injections in San Antonio are working!
Complementary Treatments
We can’t stress this enough: The body is an interconnected system, so we look beyond the numbers on the scale to support and maintain your weight loss. To address hormonal imbalances causing weight loss challenges (slow metabolism, fatigue, muscle loss), we provide hormone replacement therapy for men and women.

Body Sculpting
You’ve reached your weight loss goals! Now what? If you notice stubborn areas of fat that have been resistant to your medications, we provide body sculpting services to reshape specific areas of the body. Using noninvasive technology, body sculpting treatments complement our weight loss program. Here are our options:
Emsculpt NEO
Emsculpt NEO uses radiofrequency (RF) and high-intensity focused electromagnetic (HIFEM) energy to permanently destroy fat cells, while simultaneously building muscle. We highly recommend Emsculpt NEO to any patient on a weight loss journey, because it can target specific areas, like belly fat, while helping you stay strong and improving your workouts.

Exion Body
Exion Body targets areas with localized fat deposits while also tightening the skin. Monopolar radiofrequency and targeted ultrasound destroy fat cells, increase collagen and elastin, and repair skin’s cellular structure. Exion Body and Emsculpt NEO work especially well to target the stubborn areas of fat resistant to weight loss injections in San Antonio.
EMTONE
For those battling cellulite—fat deposits that push against the body’s tissues, making skin appear dimpled—Emtone provides a solution. This technology uses thermal and mechanical energy to improve circulation and boost collagen production in targeted areas, leading to smoother, tighter skin.
Our body sculpting services pair well together to enhance your contoured appearance. Please remember, these services complement weight loss treatments. They do not replace them. We offer body sculpting to help you achieve your aesthetic goals after you’ve achieved your wellness goals.
