​Real medical care. Real metabolic strategy. Direct access to your physician.

​

At Hennessay Medical, weight management is treated as a chronic medical condition — not a subscription service. Our Medical GLP‑1 Weight Program provides physician‑supervised semaglutide and tirzepatide therapy with comprehensive metabolic oversight, insurance advocacy, and long‑term planning.

​

Serving patients in Torrance, Palos Verdes, Redondo Beach, Manhattan Beach, Hermosa Beach, El Segundo, and the greater South Bay, we offer both in‑person and secure video visits for convenient access to expert care.

​

What Is GLP‑1 Medical Weight Loss?

​

GLP‑1 medications such as semaglutide (Wegovy®, Ozempic®) and tirzepatide (Zepbound®) work by targeting hormonal pathways involved in appetite regulation, insulin response, and metabolic signaling.

​

These medications can help:

• Reduce appetite and “food noise”

• Improve insulin resistance

• Support meaningful, sustained weight loss

• Improve cardiometabolic risk markers

• But medication alone is not a plan.

​

Successful, sustainable weight loss requires medical oversight, dose titration, lab monitoring, and long‑term strategy — which is why physician supervision matters.

 

How Semaglutide (Wegovy®, Ozempic®) Works

​

Semaglutide is a GLP‑1 receptor agonist — a medication that mimics a naturally occurring hormone in the body called glucagon‑like peptide‑1 (GLP‑1).

​

GLP‑1 is released from the intestines after eating and helps regulate appetite, insulin response, and blood sugar levels.

 

Semaglutide works by:

• Increasing satiety (helping you feel full sooner)

• Reducing hunger and “food noise”

• Slowing gastric emptying

• Stimulating insulin release when blood sugar is elevated

• Reducing glucagon secretion

 

The result is decreased caloric intake, improved metabolic signaling, and clinically meaningful weight loss when combined with lifestyle support.

​

Semaglutide is administered once weekly as a subcutaneous injection. It is gradually titrated to minimize gastrointestinal side effects such as nausea or bloating. Because of its long half‑life (approximately one week), it provides steady hormone signaling and sustained appetite regulation.

​

In large clinical trials, once‑weekly semaglutide 2.4 mg has demonstrated average weight loss of approximately 15% of initial body weight over 68 weeks when combined with lifestyle intervention.

​

Semaglutide is FDA‑approved for:

• Chronic weight management in adults with obesity (BMI over 30)

• Adults who are overweight (BMI 27)  with at least one weight‑related medical condition

• Reduction of cardiovascular risk in certain high‑risk populations

 

How Tirzepatide (Zepbound®) Works

 

Tirzepatide is a dual incretin agonist, meaning it activates two hormone pathways:

• GLP‑1 (glucagon‑like peptide‑1)

• GIP (glucose‑dependent insulinotropic polypeptide)

 

By stimulating both receptors, tirzepatide enhances appetite regulation and metabolic control beyond GLP‑1 alone.

​

Tirzepatide works by:

• Increasing fullness and satiety

• Reducing hunger and caloric intake

• Improving insulin sensitivity

• Supporting improved glucose metabolism

• Slowing gastric emptying

 

This dual‑hormone mechanism is associated with greater average weight loss compared to earlier GLP‑1 medications in clinical trials.

​

In studies of adults with obesity, once‑weekly tirzepatide has demonstrated average weight loss ranging from approximately 15% to over 20% of initial body weight, depending on dose.

​

Like semaglutide, tirzepatide is administered once weekly via subcutaneous injection and requires careful dose escalation to improve tolerability.

​

Why Physician Supervision Matters

GLP‑1 medications are powerful metabolic therapies. They are not cosmetic medications, and they are not “quick fixes.”

​

Physician supervision is important because:

​

1. Proper Patient Selection

Not every patient is an ideal candidate. We evaluate:

• BMI and metabolic risk

• History of pancreatitis

• Gallbladder disease

• Thyroid cancer risk (MEN2, medullary thyroid carcinoma)

• Pregnancy status

• Current medications

​​

2. Individualized Dosing & Titration

Starting too high or escalating too quickly increases side effects. We tailor dosing based on:

• Tolerability

• Weight response

• Blood sugar response

• GI symptoms

​​

3. Lab Monitoring

 

We may monitor:

• A1C or fasting glucose

• Lipid profile

• Liver enzymes

• Renal function

• Nutritional status during weight reduction

​​

4. Side Effect Management

Common side effects include:

• Nausea

• Constipation

• Diarrhea

• Reflux

• Fatigue

 

These are often manageable with dose adjustment, dietary modification, hydration, and supportive care.

​

5. Long‑Term Strategy

Stopping GLP‑1 therapy abruptly often leads to weight regain. Sustainable success requires:

• Strength preservation

• Adequate protein intake

• Resistance training

• Maintenance planning

• Gradual transitions when appropriate

 

6. Integrated Primary Care

Unlike national telehealth platforms, your weight management plan is integrated with your overall health — blood pressure, cardiovascular risk, metabolic markers, and long‑term disease prevention.

 

At Hennessay Medical in Torrance, you are treated by the same physician who understands your full medical history — not a rotating provider following a preset algorithm.

 

Why Choose a Physician‑Supervised GLP‑1 Program?

​

Unlike national telehealth platforms, our program is led directly by Dr. Meg Hennessay, a board‑certified Family Medicine physician in Torrance.

​

You are never diverted to a rotating provider, nurse practitioner, or algorithm‑based protocol.

 

Your care includes:

• Comprehensive metabolic evaluation (labs are $250 for screening for diabetes, cholesterol disorders, thyroid health, comprehensive metabolic panel, and blood counts)

• Medication selection based on your medical history

• Once-monthly video visits, after starting medication

• Dose titration and side‑effect management

• Ongoing lab monitoring

• Maintenance planning to prevent rebound weight gain

• Direct communication through our secure patient portal

• Optional in‑person visits at our Torrance office

 

Weight management is not one‑size‑fits‑all. Your plan should not be either.

 

Insurance Coverage & Prior Authorization Support

​

One of the biggest barriers to GLP‑1 treatment is insurance approval.

​

At Hennessay Medical, we:

• Attempt insurance coverage whenever possible

• Submit prior authorizations

• Provide required documentation

• Appeal denials when appropriate

• Offer transparent self‑pay options if coverage is excluded

​

Many patients in the South Bay come to us after being told “your insurance won’t cover it.” Often, the issue is documentation — not eligibility.

​

We advocate for our patients.

If you are searching for GLP‑1 weight loss in Torrance or the South Bay, we can determine whether semaglutide or tirzepatide is appropriate for you.

 

Ro vs Physician‑Supervised GLP‑1 Care by Dr. Hennessay

​

Many patients compare us to Ro Body or other national telehealth platforms.

​

While convenient, subscription‑based services often provide:

​

• Limited physician continuity

• Minimal lab oversight

• Little to no insurance advocacy

• No in‑person access

• Protocol‑based prescribing

​​

At Hennessay Medical, you receive:

• Direct care from the same physician

• Integrated primary care oversight

• Insurance prior authorization and appeals

• In‑person visits in Torrance

• Long‑term metabolic planning

• Accountability and continuity

 

Weight management is a chronic condition. It deserves physician‑led care.

 

Frequently Asked Questions About GLP‑1 Weight Loss

​

How much weight can I lose?

​

Results vary, but clinical trials show meaningful weight reduction when medication is combined with medical oversight and lifestyle modification.

​

How long do I need to stay on GLP‑1?

GLP‑1 therapy is often long‑term. We discuss maintenance strategies early to reduce rebound risk.

 

Does insurance cover semaglutide or tirzepatide?

Coverage varies by plan. We attempt prior authorization and appeals whenever appropriate.

 

Are compounded GLP‑1 medications safe?

We discuss FDA‑approved options first and review risks and regulatory considerations when applicable. We do not offer compounded medications in clinic.
