Functional Medicine Testing & Personalized Care in Pasadena

Understand the Systems Behind Your Health.

Understand the Systems Behind Your Health.

Your metabolism, hormones, heart health, stress response, and digestive system all play a role in how your body functions.

Pasadena Weight Loss Center's Precision Functional Medicine approach uses targeted testing and clinical evaluation to provide additional insight into metabolic, hormonal, cardiovascular, stress-response, and digestive health — helping your care team develop more individualized recommendations.

Looking Beyond Symptoms to the Bigger Picture

Precision Functional Medicine focuses on evaluating health factors and body systems that may be relevant to your symptoms, concerns, and broader wellness goals.

1

Metabolism

Your metabolic health affects energy, weight, and long-term wellness.

Hormones

Hormones involved in the body's stress response, including cortisol, can vary throughout the day and may be evaluated when clinically appropriate.

Stress Response

Your adrenal system plays a role in energy, recovery, and resilience.

Digestive Health

Digestive health can influence comfort, nutrient absorption, and overall well-being.

The goal is to gather more complete information and consider relevant health factors together — rather than looking at a single measurement in isolation.

FAQs

What Are GLP-1 Medications?

GLP-1 medications are a class of prescription drugs that not only improves blood sugar control but may also lead to weight loss. This class of drugs is commonly called glucagon-like peptide 1 (GLP-1) agonists. Weight loss can vary, depending on which GLP-1 drug you use and the dosage.

Some of the more common side effects include:

Nausea, Vomiting, Diarrhea.

Side effects can often be mitigated by correctly titrating your dosage upward, so you’ll want to ensure that you are taking the medication exactly as prescribed by your provider to minimize risk and/or severity of side effects. Anti-nausea medications such as ondansetron (generic Zofran) are also helpful to assist in mitigating nausea.

Low blood sugar levels (hypoglycemia) are a more serious risk linked to the GLP-1 class of drugs. But the risk of low blood sugar levels often only goes up if you’re also taking another drug known to lower blood sugar at the same time, such as sulfonylureas or insulin. The GLP-1 class of drugs isn’t recommended if you have a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia. Lab studies have linked these drugs with thyroid tumors in rats. But until more long-term studies are done, the risk to humans isn’t known. The GLP-1 class of drugs is also not recommended if you’ve had pancreatitis.

Is the program safe?

Care is guided by licensed healthcare professionals who consider your health history, individual needs, and clinical evaluation when determining appropriate treatment options. As with any medical care, potential risks and benefits depend on the individual and the treatments being considered.

What should I do if I miss a dosage?

Contact your healthcare provider or our clinical team for guidance before changing how you take a prescribed medication.

How is this different from dieting on my own?

A medically guided approach adds professional evaluation, personalization, structure, and ongoing support rather than relying on a generic, one-size-fits-all plan.

What happens during the consultation?

We’ll discuss your goals, health history, and previous experiences with weight loss to better understand the right path forward — with no pressure or obligation.

Are results guaranteed?

No. Results vary by patient. Your progress depends on your health profile, consistency, treatment plan, and ongoing follow-through.

I'm currently receiving treatment elsewhere. Can I still schedule a consultation?

Yes. During your consultation and medical intake, our team can review your current treatment history and discuss appropriate next steps. Any decisions involving prescription treatment are made by a qualified healthcare provider based on individual clinical evaluation.
