Conditions and Symptoms We Help Treat

Many patients feel “off” without knowing why. We help identify what’s driving those symptoms and how to improve them.

Many patients come to us feeling unheard or unsure why they don’t feel their best. Our evaluation looks at the whole picture so we can create a plan that matches your needs.

Common concerns we help address include:

Low energy or chronic fatigue ⋮ Weight gain and slow metabolism ⋮ Low libido or sexual wellness concerns ⋮ Mood changes, anxiety, irritability ⋮ Hot flashes or night sweats ⋮ Brain fog or trouble concentrating ⋮ Poor sleep or difficulty staying asleep ⋮ Muscle loss or decreased strength ⋮ Irregular menstrual cycles ⋮ Perimenopause and menopause changes ⋮ Low testosterone symptoms  ⋮ Insulin resistance or elevated A1c ⋮ Hair thinning or skin changes ⋮ Difficulty recovering from stress

If you are experiencing any of these symptoms, a deeper look at hormones, thyroid function, cortisol patterns, inflammation, nutrition, or metabolic health may provide answers.

Your safety is our highest priority. All treatments at Lake Forest Regenesis are guided by a licensed medical provider who specializes 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

  • 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.

Functional Medicine and Longevity Support

We help identify what’s underneath common symptoms so you can feel better now and protect your health long-term.

For patients who want a clearer understanding of their health, we take a deeper look at how the body is working. This may include checking inflammation, gut health, stress and cortisol levels, thyroid function, insulin and blood sugar control, nutritional status, heart and blood vessel health, and how well the cells make energy. These areas often explain why a person feels tired, gains weight more easily, or has trouble sleeping or focusing. Instead of just treating symptoms, we look for the cause. Our goal is to improve how you feel now and protect your health as you age.

A Better Path to Feeling Like Yourself Again

Many people notice changes in their body that don’t make sense: weight gain without changing their diet, brain fog for the first time, low libido, poor sleep, or stress that feels harder to recover from. Too often, they are told, “Everything looks normal,” even though they feel far from it.

Our clinic takes a different approach. We look deeper at hormone patterns, nutritional status, inflammation, thyroid function, insulin sensitivity, and other markers that influence how you feel each day. By understanding the root causes, we can guide you toward a plan that actually makes sense for your life and long-term goals.

We work with patients throughout Lake Forest and the North Shore who want private, thoughtful, and medically guided care—not quick fixes or one-size-fits-all plans.

Tree symbolizing growth, balance, and regenerative health

Peptide and Regenerative Therapies

Cutting-edge regenerative therapies tailored to your needs.

Peptides are short chains of amino acids that help signal repair, recovery, and cellular balance. They can complement hormone therapy or be used alone.

Common goals supported with peptides include:

Faster recovery from stress or exercise 

Improved sleep and daytime energy 

Better metabolic function 

Immune support 

Tissue repair and joint comfort 

Healthier skin, hair, and collagen 

Enhanced cognitive clarity and performance 

All peptide programs are medically guided to ensure safety, purity, and appropriate use

IV Therapy & Vitamin Support

Customized nutrient therapy to support performance and resilience.

IV therapy delivers vitamins, minerals, and antioxidants directly into the bloodstream so your body can use them more effectively. These infusions may support:

Immune protection 

Fatigue and low energy 

Hydration and recovery 

Metabolic support 

Skin health and collagen 

Stress resilience 

Athletic performance 

Post Workout Recovery 

Options include NAD+, Vitamin C, Myers Cocktail, amino acids, and other targeted blends. IV therapy is offered in-clinic for safety and oversight.

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.

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.

Enhancing Your Plan With Targeted Body Treatments

Strengthen the body from the inside out for better everyday function and long-term results.

While hormone and metabolic therapy improve how the body works on the inside, Emsella® and Emsculpt NEO® strengthen key muscle groups that affect daily comfort and confidence. Many patients find this combination helpful for pelvic floor support, sexual health, core strength, and body composition. This full-spectrum approach allows patients to age with better strength, control, and resilience—not just better labs.

Emsculpt NEO body contouring and muscle strengthening treatment

Emsculpt NEO®

Next-generation body contouring to strengthen, tone, and sculpt.

Emsculpt NEO® works best when it is part of a bigger plan that supports muscle, metabolism, and healthy aging. Many patients use it while working on hormone balance, GLP-1 weight loss, or peptide therapy. When hormones are optimized, the body builds and maintains muscle more easily and recovers better from stress.

Patients using GLP-1 medications often lose fat faster than muscle, so Emsculpt NEO® helps protect strength and body composition during weight loss. Peptides may also support tissue repair, performance, and energy for those who want more active lifestyles. When combined thoughtfully, Emsculpt NEO® can enhance both physical results and overall function, making it easier to stay strong, confident, and active as you age.

Emsella pelvic floor therapy for urinary and sexual health

Emsella®

Advanced pelvic floor strengthening without downtime.

Emsella® fits well into treatment plans that support pelvic health, sexual wellness, and healthy aging. Pelvic floor weakness can be linked to childbirth, menopause, low hormones, or changes in tissue quality over time. Hormone therapy may help improve vaginal comfort, sexual arousal, and tissue strength, while Emsella® strengthens the muscles that support bladder control and sexual function.

Some patients also benefit from peptide therapy or functional and regenerative medicine support for tissue repair, inflammation, or nervous system balance. When used together, these treatments address both the structural and hormonal sides of pelvic health. This combination can help patients feel more confident, comfortable, and in control in daily life and during sexual activity.
