FACTORS THAT INFLUENCE BODY WEIGHT
Body weight is influenced by multiple interacting factors across biological, environmental, and behavioral systems:
These systems communicate dynamically via neurochemical signals, endocrine feedback loops, and metabolic pathways to maintain homeostatic energy balance.
THE ROLE OF GLP-1
GLP-1 (glucagon-like peptide-1) is a naturally occurring hormone involved in glucose regulation, digestion, appetite, and satiety.
EFFECTS OF GLP-1 RECEPTOR AGONISTS
GLP-1 receptor agonists are medications that activate GLP-1 receptors. Their physiological effects can include:
Influence appetite and satiety
Signals satisfaction center in brain
Increase glucose-dependent insulin secretion
Stimulated primarily when blood glucose rises
Reduce glucagon secretion
Suppresses liver glucose release when elevated
Delay gastric emptying
Slowing rate of nutrient entry into circulation
Reduce overall food intake
Promoting feelings of sustained fullness
Semaglutide
Semaglutide is a GLP-1 receptor agonist. FDA-approved medications containing semaglutide have different indications depending on the specific product. These include type 2 diabetes and, for certain products and patient populations, chronic weight management.
Approved indications, dosage, warnings, contraindications, and precautions are specific to each product and should be reviewed in the current FDA-approved prescribing information.
Tirzepatide
Tirzepatide is a dual GIP and GLP-1 receptor agonist. GIP stands for glucose-dependent insulinotropic polypeptide. FDA-approved medications containing tirzepatide have specific indications, including type 2 diabetes and, for certain patient populations, chronic weight management.
Whether a medication is medically appropriate depends on an individual's health history, current medications, clinical findings, and other factors evaluated by a qualified healthcare professional.
Medical Weight Management
Prescription medication does not replace other components of weight management. Medical evaluation may include consideration of:
Potential Risks and Side Effects
Prescription weight-management medications may cause side effects and are not appropriate for every patient.
Common Gastrointestinal Adverse Effects:
Specific medications may have additional warnings, contraindications, precautions, and potential interactions. Patients should review current prescribing information and discuss individual risks with a healthcare professional.
FDA-Approved & Compounded Medications
FDA-approved and compounded medications are fundamentally different:
FDA-Approved
Undergone FDA review for safety, effectiveness, manufacturing quality, and labeling.
Compounded
Not FDA-approved. The FDA does not review compounded drugs for safety or quality prior to marketing.
The FDA advises that compounded drugs should generally be used when a patient's medical needs cannot be met by an available FDA-approved drug.
Patients prescribed compounded medication should obtain the prescription from a licensed healthcare professional and have it filled by an appropriately licensed pharmacy.
Questions to Discuss
With a Qualified Healthcare Professional
Continuing Research
Research into obesity, metabolism, appetite regulation, gastrointestinal hormones, and medical weight management continues to evolve. Clinical evidence, FDA-approved indications, prescribing information, and regulatory guidance may change as additional research becomes available.

Prescription medications require evaluation and prescribing by an appropriately licensed healthcare professional. Treatment decisions should be individualized based on medical history, current health, medications, potential risks, current prescribing information, and professional medical judgment. FDA approval status, prescribing information, clinical evidence, and regulatory requirements may change. Current information should be verified through the U.S. Food & Drug Administration and other recognized medical resources.
