Personalized Care for Your Weight, Hormones, Metabolism & Wellness
Looking Beyond Symptoms to Understand What May Be Affecting Your Health.
At Lake Forest Regenesis, we work with men and women who want a more personalized approach to their health.
Many patients come to us experiencing concerns such as unexplained weight gain, difficulty losing weight, fatigue, low energy, brain fog, poor sleep, decreased libido, mood changes, muscle loss, metabolic changes, or symptoms associated with perimenopause, menopause, or low testosterone.
Rather than focusing on a single symptom or laboratory value, we evaluate the broader picture.
Your care may include a detailed health assessment, laboratory testing, hormone and metabolic evaluation, medication review, nutrition and lifestyle considerations, and an individualized treatment plan based on your health history and goals.
Our goal is to help identify factors that may be contributing to how you feel and develop a medically guided plan designed around your individual needs.
Medical Weight Loss & GLP-1 Therapy
Lose weight, balance hormones, and improve energy with medical oversight.
Weight loss can be influenced by appetite regulation, insulin resistance, hormones, metabolism, nutrition, lifestyle, muscle mass, and other individual health factors.
Lake Forest Regenesis provides personalized medical weight loss for men and women using a comprehensive approach that may include GLP-1 medications such as semaglutide or tirzepatide, laboratory testing, hormone evaluation, nutritional guidance, lifestyle support, and ongoing medical monitoring when clinically appropriate.
Care begins with an assessment of your health history, previous weight-loss efforts, metabolic factors, medications, symptoms, and personal goals. Treatment plans are individualized rather than based on a one-size-fits-all protocol.
For appropriate patients, Emsculpt NEO may also be incorporated into a broader body-composition plan to help build muscle and reduce localized fat while medical weight management addresses overall weight and metabolic health.
Who Is a Good Candidate for Care?
Many patients come to us because they feel “off” but are told their labs are normal or that their symptoms are just part of aging. Our evaluation looks beyond surface numbers to understand what is really happening in the body. You may be a good candidate for our care if you:
Have symptoms that don’t match “normal” labs
Want more energy, strength, or mental clarity
Are entering perimenopause or menopause
Have signs of low testosterone
Struggle with metabolism or weight
Want support with sexual health
Prefer a personalized, thoughtful approach
Want guidance for healthy aging
If this sounds like you, a tailored medical plan may help you feel and function better with greater confidence as you age.
Who May Not Be a Candidate
We believe in safe and responsible care. Some treatments are not right for everyone, and certain situations require different types of medical support. Before starting care, we complete a detailed medical review and order labs to make sure treatment is appropriate and safe. Care may not be a good fit if you:
Are seeking unsupervised hormones or peptides
Want rapid or extreme changes without medical guidance
Are unwilling to complete labs, follow-up, or monitoring
Are pregnant or breastfeeding
Have uncontrolled medical conditions that require specialty care
Safety always comes first. If our clinic is not the right match, we will not leave you without support. We will guide you toward resources, specialists, or care settings that better meet your needs so you can move forward with confidence and clarity.
Hormone Replacement Therapy for Women
Personalized Hormone Care Through Perimenopause, Menopause & Beyond
Hormonal changes can affect much more than reproductive health.
Women experiencing fatigue, hot flashes, night sweats, poor sleep, brain fog, mood changes, decreased libido, weight gain, or changes in body composition may benefit from a comprehensive hormone evaluation.
Lake Forest Regenesis provides individualized hormone replacement therapy based on symptoms, health history, laboratory testing, and ongoing monitoring.
Treatment recommendations may address estrogen, progesterone, testosterone, thyroid-related concerns, and other factors when clinically appropriate.
Our goal is to help women better understand the changes occurring in their bodies and determine whether hormone therapy may be an appropriate part of their care.
Testosterone Replacement Therapy for Men
Evaluating Low Testosterone, Energy, Strength & Sexual Wellness
Low testosterone can affect more than sexual health.
Men experiencing decreased energy, reduced libido, loss of muscle mass, increased body fat, difficulty concentrating, reduced motivation, or changes in sexual function may benefit from a comprehensive hormone evaluation.
Lake Forest Regenesis provides individualized testosterone replacement therapy based on symptoms, health history, laboratory testing, and ongoing monitoring.
Treatment is personalized based on testosterone levels, metabolic health, body composition, cardiovascular risk factors, and other clinically relevant concerns.
Our goal is to help men better understand the factors affecting their health and determine whether testosterone replacement therapy may be an appropriate part of their care.
Functional Medicine
A More Comprehensive Look at the Factors Affecting How You Feel
Functional medicine focuses on understanding the relationships between symptoms, laboratory findings, lifestyle factors, metabolism, hormones, nutrition, and overall health.
Patients often seek functional medicine because they continue experiencing symptoms despite being told that routine laboratory results are within normal ranges.
At Lake Forest Regenesis, your evaluation may include a detailed health history, targeted laboratory testing, metabolic and hormone assessment, nutritional considerations, lifestyle factors, and other areas relevant to your symptoms.
Treatment recommendations are personalized based on your individual findings rather than following a standardized wellness protocol.
Peptide Therapy
Personalized Peptide Treatment as Part of a Broader Wellness Plan
Peptides are naturally occurring chains of amino acids that act as signaling molecules throughout the body.
Certain peptide therapies may be considered as part of individualized programs focused on metabolic health, body composition, recovery, healthy aging, or other specific wellness goals.
Peptide therapy at Lake Forest Regenesis begins with a medical evaluation to determine whether treatment is appropriate based on your health history, symptoms, goals, medications, and other relevant factors.
When peptide treatment is used, it should be part of a comprehensive medical plan rather than viewed as a stand-alone solution.
Non-Surgical Body Contouring
Building Muscle and Reducing Fat Without Surgery
Emsculpt NEO combines radiofrequency energy with high-intensity electromagnetic technology to simultaneously target muscle and fat.
The treatment is commonly used on areas such as the abdomen, buttocks, arms, thighs, and calves.
Emsculpt NEO may be appropriate for patients who are already close to their desired weight but want to improve muscle tone, strength, definition, or body contour without surgery.
A consultation helps determine whether Emsculpt NEO is appropriate based on your goals, health history, and treatment area.
Sexual & Pelvic Wellness
Treatments for Intimate Health, Pelvic Strength & Quality of Life
Sexual and pelvic health concerns can affect confidence, relationships, comfort, and everyday quality of life.
Lake Forest Regenesis offers treatment options for both men and women experiencing concerns related to sexual wellness, pelvic floor function, urinary symptoms, or changes associated with aging and hormonal health.
Depending on your needs, treatment options may include hormone evaluation, pelvic floor therapies such as Emsella, and other medically appropriate wellness treatments.
Our approach begins with understanding the underlying concern and determining which treatment options may be appropriate for you.
IV Vitamin Therapy & Wellness Injections
Nutrient Therapy Personalized to Your Individual Wellness Goals
Lake Forest Regenesis offers IV vitamin infusions and injectable nutrient therapies for patients seeking additional support for hydration, nutrient replenishment, energy, recovery, immunity, or general wellness.
Treatment options may include customized IV infusions as well as individual nutrient injections.
Because wellness needs vary from person to person, recommendations are based on your health history, symptoms, medications, and individual goals rather than automatically recommending the same infusion to everyone.
How Care Works at Lake Forest Regenesis
A Personalized, Provider-Led Approach From Evaluation Through Follow-Up
CONSULTATION
Your care begins with a discussion of your symptoms, health history, medications, previous treatments, lifestyle, and personal health goals.
ASSESSMENT
You will meet with your medical provider to review lab results, assessment, and goals, crafting a customized treatment plan.
PROGRAM
Your personalized treatment plan is adjusted as lab results and progress are reviewed to ensure optimal results.
MONITORING
We monitor symptoms, laboratory values when appropriate, treatment response, potential side effects, and changes in your health.
Clinical Oversight & Safety
Your safety is our highest priority. All treatments at Lake Forest Regenesis are guided by a licensed medical provider with a clinical focus in hormone and metabolic health. We follow a structured process to confirm that treatment is appropriate, safe, and aligned with your goals. This includes a detailed history, targeted lab testing, review of medical risks, and regular follow-up to monitor progress. Medications are obtained from trusted compounding or specialty pharmacies to ensure purity and dosage accuracy.
Hormone therapy, GLP-1 medications, peptide protocols, and IV treatments are never provided without proper evaluation or supervision. If care is not appropriate, we will explain why and help direct you to options that better fit your needs. Our goal is to support long-term wellness in a way that is medically responsible, transparent, and patient-centered
Clinical Safety Panel
Before starting treatment, we complete a structured safety review to ensure the plan is clinically appropriate. This may include:
Medical history review
Medication and supplement review
Relevant past diagnoses and procedures
Baseline laboratory testing
Assessment of cardiovascular and metabolic risks
Pregnancy and breastfeeding considerations
Review of contraindications and precautions
After treatment begins, our team monitors response, adjusts dosing as needed, and orders follow-up labs on a regular schedule. This process helps reduce risks, improve outcomes, and support you safely over time.
