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.
Our Lake Forest Office
Progress You Can Measure
Your care can include an in-office body composition scan to track changes in fat and muscle, not just the number on the scale.

- Results Reviewed With You

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
Hormone Care Through Perimenopause & Menopause
Hormonal changes can affect much more than reproductive health. Women experiencing fatigue, hot flashes, night sweats, poor sleep, brain fog, mood changes, low libido, or weight gain may benefit from a comprehensive hormone evaluation.
Our individualized hormone therapy is based on your symptoms, history, lab testing, and ongoing monitoring, and may address estrogen, progesterone, testosterone, or thyroid concerns when appropriate.
Testosterone Replacement Therapy for Men
Evaluating Low T, Energy, Strength & Libido
Low testosterone can affect much more than sexual health. Men experiencing low energy, reduced libido, muscle loss, added body fat, poor focus, or low motivation may benefit from a comprehensive hormone evaluation.
Our individualized testosterone therapy is based on your symptoms, history, lab testing, and ongoing monitoring, tailored to your levels, metabolic health, and cardiovascular risk.

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.
Body Contouring
Building Muscle and Reducing Fat Without Surgery
Emsculpt NEO uses radiofrequency and electromagnetic energy to target muscle and fat at the same time, commonly on the abdomen, buttocks, arms, thighs, and calves.
It may suit patients close to their desired weight who want to improve muscle tone, strength, or body contour without surgery. A consultation helps determine whether it fits your goals, health history, and treatment area.
Sexual & Pelvic Wellness
Intimate Health, Pelvic Strength & Quality of Life
Sexual and pelvic health concerns can affect confidence, relationships, comfort, and everyday quality of life. We offer care for men and women with sexual, pelvic floor, urinary, or hormone-related concerns.
Depending on your needs, options may include hormone evaluation, pelvic floor therapies such as Emsella, and other medically appropriate treatments, starting with understanding the underlying concern.
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
Initial Consultation
Your care begins with a 90-minute visit with Allana covering your symptoms, health history, medications, lifestyle, and goals. Labs are drawn at this visit.
Health Assessment
Once your results are back, you return for a 90-minute follow-up to review your labs, assessment, and goals and build your personalized treatment plan.
Care Plan
Your personalized treatment plan is reviewed and adjusted over time as your lab results, symptoms, and progress are evaluated.
Ongoing 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 chosen for quality and dosing 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.
