Personalized GLP-1 Therapy for Medical Weight Loss
Provider-Guided Treatment Focused on Appetite, Metabolic Health & Long-Term Weight Management
Lake Forest Regenesis provides personalized GLP-1-based medical weight loss for men and women in Lake Forest, Chicago’s North Shore, and Lake County.
Treatment may include semaglutide- or tirzepatide-based therapy when clinically appropriate, along with medical evaluation, nutritional and lifestyle guidance, progress monitoring, and ongoing provider oversight.
Care is led by Allana Bush, FNP-C, a family nurse practitioner with 22 years of healthcare experience and a clinical focus in medical weight management, hormone optimization, and metabolic health.

What Is GLP-1 Therapy?
Prescription Treatment for Weight Management
GLP-1 therapy uses prescription medications that act on appetite, fullness and blood sugar pathways and may support weight management in eligible patients as part of a medical program. Semaglutide acts on GLP-1 receptors, while tirzepatide acts on both GIP and GLP-1 receptors; they are different medications with individual considerations.
Brand-name versions are FDA-approved for chronic weight management. Compounded versions are prepared by an FDA-registered compounding pharmacy, and compounded medications are not FDA-approved. Your provider reviews your history, medications and goals, explains your options, and builds a personalized plan when treatment is appropriate.
How GLP-1 Weight Loss Works
Helping Manage Hunger and Fullness Alongside Healthy Habits
GLP-1-based medications influence signals involved in hunger, fullness and food intake, which may help eligible patients manage portions and reduce overall calorie intake. Treatment generally starts at a lower dose that is increased gradually, and responses vary from person to person.
Follow-up lets your provider monitor progress, appetite changes, potential side effects and overall health so your plan can be adjusted. Nutrition, activity, sleep and sustainable habits remain important for long-term weight management, during treatment and after.
Semaglutide vs. Tirzepatide
Understanding Two Common Medication Options for Medical Weight Management
Semaglutide and tirzepatide are prescription medications used in medical weight-management programs, but they work through different pathways. Semaglutide acts on GLP-1 receptors, while tirzepatide acts on both GIP and GLP-1 receptors.
Both medications can influence appetite, fullness, food intake, and metabolic health, but the best option depends on the individual rather than choosing one medication based on popularity alone.
At Lake Forest Regenesis, your provider considers health history, current medications, previous weight-loss efforts, treatment goals, potential risks, and response to therapy when determining which approach may be appropriate.
Treatment is personalized and monitored over time, with adjustments made based on progress, tolerance, side effects, and changing health needs.

What to Expect From GLP-1 Treatment
A Gradual, Monitored Approach That Evolves With Your Response
GLP-1-based treatment is typically introduced gradually so your provider can evaluate tolerance, appetite changes, side effects, and overall response.
During treatment, patients may notice changes in hunger, fullness, portion size, and eating patterns as medication begins to take effect.
Progress varies from person to person, so treatment is adjusted based on individual response, health needs, and medication tolerance rather than following the same timeline for everyone.
Regular follow-up helps your provider determine whether the current approach remains appropriate and supports a transition toward sustainable, long-term weight management.
Benefits of GLP-1 Therapy
Personalized Treatment Designed Around Your Health, Goals & Response
Appetite Support
GLP-1 medications may help reduce appetite and increase fullness, which can make it easier to follow a nutrition plan and build consistent eating habits. Individual results vary and are monitored.
Metabolic Support
Treatment may support blood sugar regulation and other metabolic health markers when appropriate, with labs and follow-up visits used to track how your body is responding over time.
Personalized Treatment
Medication choice and dosing are individualized around your health history, goals, and side effects, with adjustments made gradually so treatment stays tolerable and appropriate for you.
Lasting Results
Your plan looks beyond the scale to help you maintain results, including nutrition, muscle preservation, and planning for what happens if medication is reduced or stopped, with support from your provider.
Medication Is Only Part of the Program
Supporting Long-Term Progress With Nutrition, Movement & Sustainable Habits
GLP-1 medications can support weight management, but lasting progress involves more than medication alone.
Nutrition, physical activity, sleep, stress management, and daily routines can all influence weight, metabolic health, and long-term maintenance.
At Lake Forest Regenesis, treatment is designed to help patients build habits that support their medical plan while adapting to changes in appetite, energy, body composition, and overall health.
As progress continues, your provider can help adjust the plan so treatment remains aligned with your health needs, lifestyle, and long-term weight-management goals.
Everyday health concerns outside your GLP-1 plan can be managed through Direct Primary Care, a separate membership with the same provider.

Is GLP-1 Therapy Right for You?
Who Treatment May Fit, Safety and Important Information
Who May Be a Candidate for GLP-1 Therapy?
GLP-1-based treatment may be appropriate for adults who have struggled to lose or maintain weight through nutrition and exercise alone or who have weight-related health concerns.
Candidates should be willing to participate in ongoing medical follow-up, lifestyle changes, and long-term weight management rather than viewing medication as a quick fix.
Eligibility depends on factors such as health history, current medications, weight-related goals, previous treatment efforts, and potential risks.
A consultation with your provider is necessary to determine whether GLP-1-based therapy may be an appropriate option for your individual needs.
Who May Not Be a Candidate for GLP-1 Therapy?
GLP-1-based medications are not appropriate for every patient, and certain health conditions or medications may affect whether treatment can be used safely.
Treatment may not be recommended during pregnancy or breastfeeding, or for patients with certain medical histories, contraindications, medication interactions, or other clinical concerns.
Your provider will review your medical history, current medications, symptoms, and treatment goals before recommending therapy.
If GLP-1 treatment is not appropriate, other medical weight-management options may be discussed based on your individual health needs.
Clinical Oversight & Safety
Before GLP-1-based treatment is recommended, your provider reviews your medical history, current medications, symptoms, treatment goals, and potential contraindications.
GLP-1 medications can cause side effects and are not appropriate for every patient. Individual risks and benefits should be considered before treatment begins.
During treatment, follow-up may include monitoring weight progress, medication tolerance, side effects, symptoms, and laboratory findings when appropriate.
Your treatment plan may be adjusted, paused, or discontinued based on your response, changing health needs, or clinical concerns to help support safe and appropriate care.
When We Refer to a Specialist
If GLP-1 therapy is not a safe fit, or your history includes concerns such as pancreatitis, gallbladder disease, a personal or family history of certain thyroid cancers, or a possible eating disorder, Allana refers you to the right specialist and helps coordinate next steps.

Frequently Asked Questions
Clear Answers About GLP-1 Therapy at Lake Forest Regenesis
Is GLP-1 therapy the same as semaglutide or tirzepatide?
Not exactly. GLP-1 therapy is the broader category of medications that act on GLP-1 receptors. Semaglutide is a GLP-1 receptor agonist, while tirzepatide acts on both GIP and GLP-1 receptors. Both may be used in medical weight-management programs when clinically appropriate.
How quickly can I expect to lose weight?
Results vary based on the medication, dose, starting health, lifestyle, and individual response. Treatment focuses on steady progress rather than promising a specific amount or rate of weight loss.
What side effects can occur with GLP-1-based treatment?
Common side effects can include nausea, digestive changes, decreased appetite, constipation, or diarrhea. Your provider monitors tolerance and may adjust treatment when necessary.
Do I still need to focus on nutrition and exercise?
Yes. GLP-1 medications work best as part of a broader plan that includes nutrition, physical activity, sleep, and sustainable lifestyle habits.
How long will I need GLP-1 therapy?
Treatment length varies by patient. Your provider considers progress, medication tolerance, health needs, and long-term weight-management goals when determining how long treatment should continue.
What happens when I reach my goal or stop medication?
Your plan may transition toward long-term weight maintenance. Some patients continue medication, while others adjust treatment based on their progress, health, and individual needs.

A Personal Message From Your Provider
GLP-1 Treatment Should Be Personalized, Monitored & Part of a Bigger Plan
“My goal is to help patients use GLP-1-based treatment in a way that is medically responsible, realistic, and personalized. Medication can be a helpful tool for some patients, but it should never replace thoughtful evaluation, healthy habits, and ongoing medical support.
I want patients to understand how treatment works, what to expect, and why their plan may change over time. The goal is to create an approach that supports sustainable weight management, metabolic health, and long-term progress.”
