Medical Weight Loss & Obesity Medicine
Physician-Supervised Care for Weight Loss, Metabolic Health, and Long-Term Wellness
Losing weight can be difficult—even when you are trying to eat better, exercise consistently, and make healthier choices.
That does not mean you lack discipline.
Body weight is influenced by a complex combination of genetics, appetite hormones, metabolism, sleep, stress, medical conditions, medications, environment, activity level, and previous weight-loss attempts. Obesity is recognized as a serious chronic disease influenced by many factors, not simply a failure of willpower.
At Suwanee Family Physicians, our medical weight-loss program provides personalized, physician-supervised care for adults who want to lose weight, improve their health, and better manage weight-related medical conditions.
The program is led by Dr. John Shih, a board-certified family physician and diplomate of the American Board of Obesity Medicine. Certification as an ABOM diplomate reflects specialized knowledge and competency in the practice of obesity medicine.
Whether you are interested in nutrition and lifestyle treatment, GLP-1 medication, tirzepatide, another FDA-approved weight-management medication, or a comprehensive evaluation of the medical factors affecting your weight, our goal is to help you create a treatment plan based on your complete health—not a one-size-fits-all diet.
Schedule your appointment today to learn whether physician-supervised medical weight loss is appropriate for you.
What Is Medical Weight Loss?
Medical weight loss is a structured approach to weight management directed by a qualified healthcare provider.
Unlike many commercial programs that focus primarily on calorie restriction, meal replacements, supplements, or short-term challenges, medical weight loss considers the biological and medical reasons a person may have difficulty losing weight or keeping it off.
A physician-supervised program may include:
- Review of your medical and weight history
- Physical examination
- Evaluation of medications that may affect weight
- Assessment of weight-related medical conditions
- Laboratory testing when appropriate
- Nutrition guidance
- Physical activity recommendations
- Sleep and stress evaluation
- Behavioral strategies
- Prescription weight-management medication
- GLP-1 or related treatment when appropriate
- Monitoring for side effects
- Long-term weight-maintenance planning
Prescription medication is not required for every patient. It is one possible component of a broader treatment plan.
What Is Obesity Medicine?
Obesity medicine is a field of medical care focused on the prevention, evaluation, treatment, and long-term management of overweight, obesity, and related health problems.
An obesity medicine physician looks beyond the number on the scale to evaluate factors such as:
- Appetite and fullness
- Metabolic health
- Blood sugar
- Insulin resistance
- Blood pressure
- Cholesterol
- Sleep
- Stress
- Hormonal changes
- Current medications
- Mobility
- Previous weight-loss attempts
- Family history
- Weight-related complications
- The larger goals may include:
- Lowering cardiovascular risk
- Improving blood pressure
- Improving blood sugar
- Reducing the risk of type 2 diabetes
- Improving sleep apnea
- Reducing joint strain
- Preserving mobility
- Supporting liver health
- Improving energy and physical function
- Helping patients maintain progress over time
The purpose is not simply to help someone reach a particular clothing size.
Obesity treatment may include lifestyle changes, prescription medication, metabolic or bariatric surgery, or a combination of approaches depending on the individual patient.

Medical Weight Loss Is More Than a Prescription
GLP-1 medications have drawn enormous attention, but medical weight management should not begin and end with an injection.
Effective treatment requires understanding:
- Why weight gain occurred
- Which health conditions may be involved
- Whether medication is appropriate
- Which medication offers the best balance of benefits and risks
- How nutrition will be maintained
- How muscle will be preserved
- How side effects will be managed
- How progress will be measured
- What will happen if insurance coverage changes
- How weight will be managed long term
At Suwanee Family Physicians, medical weight loss is incorporated into the patient’s overall healthcare.
That means Dr. Shih can evaluate weight alongside conditions such as high blood pressure, prediabetes, diabetes, high cholesterol, thyroid concerns, sleep problems, and medication use.
Why Choose a Board-Certified Obesity Medicine Physician?
Many businesses now advertise weight-loss injections. The training and involvement of the person directing care can vary significantly.
Dr. John Shih is board-certified in Family Medicine and is a diplomate of the American Board of Obesity Medicine. His background allows him to provide weight-management care within the context of primary care and long-term health. The practice’s existing program has provided physician-led medical weight-loss care since 2008.
Working with an obesity medicine physician can be especially valuable when you:
- Have several medical conditions
- Take multiple medications
- Have experienced repeated weight regain
- Are considering prescription medication
- Have diabetes or prediabetes
- Have high blood pressure
- Have sleep apnea
- Have concerns about side effects
- Need help choosing among treatment options
- Want ongoing medical monitoring
The focus should be safe, evidence-based treatment—not simply dispensing medication.
Who May Benefit From Medical Weight Loss?
Medical weight management may be appropriate for adults who:
- Have obesity
- Have overweight plus a weight-related medical condition
- Have repeatedly lost and regained weight
- Have difficulty controlling hunger or cravings
- Have tried lifestyle changes without lasting success
- Have high blood pressure
- Have prediabetes or type 2 diabetes
- Have high cholesterol
- Have obstructive sleep apnea
- Have fatty liver disease
- Have PCOS or insulin resistance
- Experience joint pain or limited mobility
- Take medication that may contribute to weight gain
- Want to discuss GLP-1 or other prescription treatment
- Need help maintaining previous weight loss
BMI is often used as an initial screening tool, but it should not be the only measure considered.
Your physician may also evaluate:
- Waist circumference
- Blood pressure
- Blood sugar
- Cholesterol
- Physical function
- Weight-related symptoms
- Medical history
- Body composition
- Personal treatment goals

What Happens During a Medical Weight-Loss Consultation?
The first visit is designed to understand your health and identify appropriate treatment options.
Your evaluation may include a discussion of:
Your Weight History
Dr. Shih may ask:
- When weight gain began
- Whether your weight changed after pregnancy, menopause, illness, injury, or medication
- Which weight-loss programs you have tried
- How much weight you lost previously
- How long you maintained the loss
- What made previous plans difficult
Sleep and Stress
Poor sleep, sleep apnea, shift work, and chronic stress can make weight management more difficult.
Your Medical History
Weight can be connected with:
- Diabetes
- Prediabetes
- High blood pressure
- High cholesterol
- Sleep apnea
- Thyroid conditions
- PCOS
- Joint disease
- Cardiovascular disease
- Fatty liver disease
- Depression or anxiety
- Chronic pain
Your Eating Patterns
The evaluation may address:
- Meal timing
- Portion sizes
- Hunger
- Fullness
- Cravings
- Snacking
- Emotional eating
- Sugary drinks
- Restaurant meals
- Protein intake
- Alcohol
- Previous restrictive diets
Your Medications
Some medications may contribute to increased appetite, fluid retention, fatigue, or weight gain.
Do not stop prescribed medication on your own. Dr. Shih can review whether a medication may be affecting your weight and whether an alternative should be discussed.
Physical Activity and Mobility
Your plan should account for:
- Current fitness
- Joint pain
- Injuries
- Work schedule
- Physical limitations
- Exercise experience
- Activities you realistically enjoy
Laboratory Testing
Depending on your health and symptoms, testing may be recommended to evaluate:
- Blood sugar
- Cholesterol
- Thyroid function
- Liver function
- Kidney function
- Other relevant health markers
The purpose is to create an individualized medical plan—not to place every patient on the same diet or medication.
What Treatments Are Available?
Medical weight management can include several types of treatment.
Nutrition and Lifestyle Treatment
Lifestyle care remains important whether or not medication is prescribed.
Recommendations may address:
- Protein
- Fiber
- Portion sizes
- Meal planning
- Hydration
- Reducing highly processed foods
- Physical activity
- Resistance training
- Sleep
- Stress
- Long-term behavior change
Lifestyle treatment should be realistic and sustainable. Extremely restrictive plans often become difficult to maintain.
Prescription Weight-Management Medication
When lifestyle treatment alone is not enough, a healthcare professional may recommend medication. Weight-management medication should still be used alongside healthy eating and physical activity.
FDA-approved long-term weight-management medications include several options, such as:
- Orlistat
- Phentermine-topiramate
- Naltrexone-bupropion
- Liraglutide
- Semaglutide
- Tirzepatide
The best medication depends on the patient’s health, contraindications, previous treatment, side-effect risk, cost, insurance coverage, and preferences.

- Phentermine-topiramate
- Naltrexone-bupropion
- Liraglutide
- Semaglutide
- Tirzepatide
The best medication depends on the patient’s health, contraindications, previous treatment, side-effect risk, cost, insurance coverage, and preferences.
GLP-1 Medications
GLP-1 receptor agonists affect pathways involved in appetite, fullness, digestion, and blood sugar regulation.
Patients may experience:
- Reduced hunger
- Feeling full sooner
- Longer-lasting fullness
- Smaller portions
- Reduced food intake
Semaglutide is a GLP-1 receptor agonist.
Wegovy is a semaglutide product approved for chronic weight management in qualifying patients. Other semaglutide brands have different FDA-approved indications.
Tirzepatide
Tirzepatide acts on both GIP and GLP-1 receptors.
Zepbound is approved for chronic weight management in qualifying adults when used with a reduced-calorie diet and increased physical activity. FDA eligibility generally includes adults with a BMI of 30 or higher, or a BMI of 27 or higher with at least one weight-related condition.
Zepbound has also received FDA approval for moderate-to-severe obstructive sleep apnea in adults with obesity.
Mounjaro contains tirzepatide but has a different FDA-approved indication.
Bariatric Surgery Referral
Some patients may benefit from evaluation for metabolic or bariatric surgery.
Medical weight-loss treatment and surgery are not competing approaches. An obesity medicine physician can help determine when nonsurgical care is appropriate and when surgical evaluation should be considered.
Who Qualifies for GLP-1 Weight-Loss Medication?
Adults are generally considered for FDA-approved chronic weight-management medication when they have:
- A BMI of 30 or higher, or
- A BMI of 27 or higher with at least one qualifying weight-related medical condition
Examples may include:
- High blood pressure
- Type 2 diabetes
- High cholesterol
- Obstructive sleep apnea
- Cardiovascular disease
Meeting these criteria does not guarantee that a particular medication is safe or appropriate.
Dr. Shih will also review:
- Pregnancy plans
- Current medications
- Gastrointestinal symptoms
- Pancreatitis history
- Gallbladder history
- Kidney function
- Family and personal medical history
- Previous reactions
- Ability to maintain nutrition and hydration
- Product-specific contraindications and warnings

Semaglutide vs. Tirzepatide
Patients often ask which medication is better.
Semaglutide and tirzepatide can both support meaningful weight loss, but they work differently:
- Semaglutide acts on GLP-1 receptors
- Tirzepatide acts on both GIP and GLP-1 receptors
Tirzepatide has produced greater average weight reductions in some clinical comparisons, but averages do not determine which medication is best for an individual patient.
The decision should also account for:
- Medical history
- Cardiovascular disease
- Diabetes
- Sleep apnea
- Side-effect tolerance
- Contraindications
- Insurance
- Cost
- Availability
- Patient preference
- Response to previous treatment
Semaglutide also has an FDA-approved indication to reduce major cardiovascular events in certain adults with established cardiovascular disease and overweight or obesity.

How Do GLP-1 Medications Help With Weight Loss?
GLP-1 medications do not directly “melt fat.”
They can support weight loss by affecting biological signals related to hunger and food intake.
Depending on the medication, they may:
- Reduce appetite
- Increase fullness
- Slow stomach emptying
- Reduce calorie intake
- Improve blood sugar regulation
- Make smaller portions easier to maintain
The effect differs from person to person.
Medication does not replace the need for:
- Adequate protein
- Healthy food choices
- Hydration
- Physical activity
- Strength training
- Sleep
- Medical monitoring
Learn more: How Do GLP-1 Medications Help With Weight Loss?
What Are the Side Effects of GLP-1 Medications?
The most common side effects involve the digestive system.
These may include:
- Nausea
- Vomiting
- Constipation
- Diarrhea
- Bloating
- Indigestion
- Abdominal discomfort
- Reduced appetite
- Fatigue
Side effects may be more noticeable when medication is started or when the dose increases.
Gradual dose escalation can help improve tolerability.
Serious risks vary by medication and can include:
- Pancreatitis
- Gallbladder problems
- Kidney injury associated with dehydration
- Severe gastrointestinal symptoms
- Allergic reactions
- Low blood sugar when combined with certain diabetes medications
- Product-specific thyroid warnings
Patients should receive medication-specific counseling and know when to contact the physician.
Learn more: What Are the Side Effects of GLP-1 Medications?
How Much Weight Can You Lose?
Results vary.
Clinical-trial averages can help patients understand the potential effect of treatment, but they cannot predict exactly how much one individual will lose.
Results depend on:
- Medication
- Dose
- Treatment duration
- Starting weight
- Diabetes status
- Nutrition
- Physical activity
- Sleep
- Stress
- Medication adherence
- Side effects
- Other health conditions
Weight loss is often measured as a percentage of starting body weight.
For example:
- 5% of 200 pounds is 10 pounds
- 10% is 20 pounds
- 15% is 30 pounds
- 20% is 40 pounds
Even modest weight loss may improve blood pressure, blood sugar, cholesterol, mobility, and other measures of health.
The scale should not be the only measure of progress.

What Should You Eat While Taking a GLP-1 Medication?
Reduced appetite can make it difficult to consume enough protein, fluids, fiber, vitamins, and minerals.
Treatment should not become a competition to eat as little as possible.
Patients should generally focus on:
- Adequate protein
- Vegetables
- Fruit
- Whole grains
- Beans
- Healthy fats
- Smaller meals
- Eating slowly
- Stopping when comfortably full
- Drinking fluids consistently
- Limiting very fatty or greasy meals
- Reducing sugary drinks and highly processed foods
Muscle preservation is especially important during weight loss.
A strong plan may include:
- Protein at each meal
- Resistance exercise
- Regular activity
- Adequate nutrition
- Monitoring strength and function
Patients with diabetes, kidney disease, digestive conditions, or other dietary restrictions need individualized recommendations.
Learn more: What Should I Eat While Taking a GLP-1 Medication?
How Long Do Patients Stay on GLP-1 Medication?
There is no universal treatment timeline.
Certain GLP-1 and related medications are approved for long-term weight management. Treatment may continue while:
- The medication remains effective
- Benefits outweigh risks
- Side effects remain manageable
- The patient can access treatment
- No contraindication develops
- The patient wants to continue
Obesity is a chronic condition, and the biological effects that support weight loss may diminish after treatment ends.
Reaching a goal weight does not automatically mean treatment should stop.
The maintenance plan may include:
- Continuing medication
- Adjusting the dose
- Changing medication
- Increased lifestyle support
- Monitoring without medication
- Another medical or surgical approach

Conditions Commonly Connected With Being Over Weight
Weight management can affect many aspects of health.
High Blood Pressure
Excess weight may contribute to hypertension and increased cardiovascular risk.
Improved weight management may support healthier blood pressure, but prescribed medication should not be stopped without medical guidance.
Prediabetes and Type 2 Diabetes
Weight loss may improve insulin sensitivity and blood sugar.
Patients taking diabetes medication require careful monitoring because reduced intake and weight changes can affect glucose levels.
High Cholesterol
Nutrition, activity, weight loss, genetics, and medication all influence cholesterol.
Obstructive Sleep Apnea
Obesity is a major risk factor for sleep apnea.
Symptoms may include:
- Loud snoring
- Gasping during sleep
- Morning headaches
- Daytime sleepiness
- Difficulty concentrating
Weight management may improve sleep apnea in some patients, but it does not replace proper diagnosis or treatment.
Joint Pain
Excess weight can increase stress on weight-bearing joints and make physical activity more difficult.
Treatment plans should account for pain, mobility, and safe forms of activity.
Fatty Liver Disease
Weight and metabolic health are closely related to liver fat and inflammation.
PCOS and Insulin Resistance
PCOS may affect weight, appetite, blood sugar regulation, menstrual cycles, and fertility.
Treatment should consider the patient’s complete medical and reproductive health.
What Happens When Treatment Stops?
Some patients notice:
- Increased hunger
- Reduced fullness
- Larger portions
- Return of food cravings
- Weight regain
- Changes in blood sugar
- Return of weight-related symptoms
Weight regain after stopping treatment does not mean a patient failed.
It may reflect the return of biological appetite signals and the chronic nature of obesity.
Before treatment ends, patients should have a maintenance plan that may include:
- Nutrition support
- Protein planning
- Resistance exercise
- Regular weight monitoring
- Continued follow-up
- Another medication
- Treatment of related medical conditions
- Early response to weight regain
Never stop prescribed medication without discussing the plan with the prescriber.

Medical Weight Loss vs. Commercial Weight-Loss Programs
A commercial program may provide useful accountability and structure, but it may not be equipped to evaluate complex medical concerns.
Physician-supervised weight management may be more appropriate when you:
- Have obesity-related health conditions
- Take several medications
- Have experienced repeated weight regain
- Have unexplained weight changes
- Are considering prescription treatment
- Have diabetes or prediabetes
- Need laboratory testing
- Have concerning symptoms
- Need coordination with primary care
- Want long-term medical monitoring
A safe program should offer realistic expectations and should not promise:
- Guaranteed results
- Effortless weight loss
- Permanent results from a short program
- A universal medication
- A supplement that “resets” metabolism
- Rapid weight loss without risk
- Medication without medical evaluation
NIDDK recommends choosing programs that focus on realistic goals, healthy habits, ongoing support, and long-term maintenance.
Why Weight Regain Happens
The body often resists weight loss.
After losing weight, some people experience:
- Increased hunger
- Reduced fullness
- Lower energy expenditure
- Stronger food cues
- Greater difficulty maintaining portions
- Return of previous habits
- Reduced activity
This helps explain why short-term diets frequently produce temporary results.
Long-term treatment may require:
- Continued medical care
- Medication
- Nutrition planning
- Physical activity
- Strength training
- Sleep treatment
- Stress management
- Early intervention when weight begins returning
Weight regain should be treated as a medical challenge—not a moral failure.
How Progress Is Measured
Medical weight-loss progress should not rely exclusively on pounds.
Depending on the patient, Dr. Shih may monitor:
- Weight
- Waist circumference
- Blood pressure
- Blood sugar
- A1C
- Cholesterol
- Liver markers
- Energy
- Mobility
- Sleep quality
- Medication needs
- Strength
- Appetite
- Side effects
- Quality of life
A patient may be making meaningful health progress even during a temporary weight plateau.
Frequently Asked Questions About Medical Weight Loss
Do I need diabetes to receive GLP-1 treatment?
No. Certain medications are specifically FDA-approved for chronic weight management in qualifying patients without diabetes.
What BMI qualifies for medical weight-loss medication?
Adults may generally be considered with a BMI of 30 or higher, or 27 or higher with a qualifying weight-related condition. Individual products and patient circumstances must still be reviewed.
Will I automatically receive semaglutide or tirzepatide?
No. Dr. Shih will evaluate whether medication is appropriate and whether another treatment may be safer or more suitable.
Is medical weight loss only for people with severe obesity?
No. Adults with overweight and related health conditions may also benefit.
Can I participate if I have high blood pressure?
Possibly. High blood pressure is one of the health conditions commonly evaluated in medical weight management.
Are GLP-1 medications safe?
They can be appropriate and effective for qualifying patients, but they carry side effects, contraindications, warnings, and medication-specific risks. Proper evaluation and follow-up are important.
Is tirzepatide the same as semaglutide?
No. Semaglutide primarily acts on GLP-1 receptors. Tirzepatide acts on GIP and GLP-1 receptors.
Is Wegovy the same as Ozempic?
They contain semaglutide but have different FDA-approved indications and dosing information.
Is Zepbound the same as Mounjaro?
They contain tirzepatide but have different FDA-approved indications.
How quickly will I lose weight?
Results vary. Early doses are often used to help the body adjust, and meaningful weight loss occurs over time.
Can I stop medication after reaching my goal?
Possibly, but stopping may lead to increased hunger and weight regain. The decision should be made with your physician.
Does insurance cover GLP-1 treatment?
Coverage varies by insurance plan, employer benefits, diagnosis, prior-authorization requirements, and medication formulary.
Can I use compounded semaglutide or tirzepatide?
Compounded drugs are not FDA-approved, and FDA has warned about dosing errors, fraudulent products, quality concerns, and risks associated with unapproved compounded GLP-1 products. Treatment options should be discussed carefully with a qualified prescriber.
