Tired, gaining weight and not feeling like yourself: what a medical consult looks at

Several things changed at once, and no single explanation fits

You are sleeping but waking up tired. Weight has crept on despite eating the way you always have, and it will not come off the way it used to. Your mood is flatter, your workouts recover slower, your skin looks different in photos, and your interest in intimacy has faded. Each of these alone would be easy to dismiss. Together, they add up to a feeling many of my clients describe the same way: I do not feel like myself.

I am Jennifer Simon, BSN, RN, RFNP, and I serve as Chief Operating Officer of ReGen & Aesthetics Concierge of Texas in Dallas. Our clinic works in medical weight loss, hormone optimization, regenerative therapies and aesthetics, and I spend as much of my time educating people as treating them. This article is that education. It is general information about how a careful medical evaluation approaches these complaints, not medical advice for you, and nothing here predicts a result. Decisions about your health belong in a conversation with a licensed provider who has examined you and reviewed your labs.

Why these symptoms travel together

Energy, body composition, sleep, mood and sexual health are regulated by overlapping systems rather than separate ones. Thyroid function, sex hormones such as testosterone and estrogen, insulin and blood sugar regulation, cortisol and stress, sleep quality, nutrition, medications and simple aging all influence one another. When one shifts, others often follow, which is why a person can arrive with five complaints that turn out to share two or three underlying contributors.

This is also why self-diagnosis from a single symptom goes wrong so often. Fatigue can come from low iron, an underactive thyroid, poor sleep, depression, a medication side effect, low testosterone or several of these at once. Weight gain in midlife may involve changes in muscle mass, appetite regulation, insulin sensitivity and hormones, and the mix is different for every person. A provider cannot know which applies to you from a conversation alone, and neither can you. That is what laboratory work is for.

In my experience, the people who get the most out of a consultation are the ones who come expecting an investigation rather than a prescription. The investigation is where the value is.

What you can honestly assess at home before any appointment

Keep a two-week log. Record when you go to bed and wake, how rested you feel, what you eat and drink including alcohol and caffeine, how often you move and how hard, and how your energy and mood run through the day. Note any medications and supplements, including anything you bought online. Write down when the changes started and whether anything happened around that time: a job change, a loss, an illness, a new prescription, menopause or perimenopause, a drop in activity.

Then be candid about the basics. Are you sleeping seven hours or scrolling until one in the morning? Has protein intake fallen while snacking rose? Are you drinking more than you used to? These are not moral questions. They are the variables a provider will ask about, and the log turns vague impressions into information. Gather any lab results from the past two years and your family history of thyroid disease, diabetes and heart disease, because they shape what should be tested.

• Two weeks of sleep, food, alcohol, caffeine, activity and energy notes
• A list of every medication and supplement, with doses
• When the changes began and what else changed around then
• Prior lab results and your family medical history
• What you most want to be different, in plain words

When to see your primary care provider first

Some symptoms belong with your primary care provider or an emergency department before anyone discusses optimization. Chest pain, shortness of breath, fainting, sudden severe headache, unexplained rapid weight loss, blood in the stool or urine, a lump, or new confusion are not wellness questions. The same is true if you have a diagnosed condition such as heart disease, diabetes or a hormone-sensitive cancer; your existing care team needs to be part of any plan.

For the gradual, cumulative picture of fatigue, weight and feeling unlike yourself, a consultation with a clinic that looks at hormones, metabolism and the whole person is a reasonable next step, and it should begin with a thorough history and comprehensive labs, not with a treatment menu. If a provider offers you hormones or a weight loss medication without drawing blood and reviewing your history, in my view that is a reason to keep looking.

What a consultation at our clinic involves

Care at ReGen & Aesthetics Concierge of Texas is delivered by advanced practice providers. A first visit is a conversation and an examination: your history, your log if you kept one, your goals and your concerns, followed by comprehensive bloodwork ordered for your situation. Depending on the picture, that may include hormone panels, thyroid, metabolic and cardiometabolic markers, blood counts and lipids. We review the results with you and explain what they mean, including when they are normal and the answer lies elsewhere.

From there, options are discussed, not assigned. For some people the discussion involves a medically managed weight loss program using GLP-1 medications such as semaglutide or tirzepatide, which are prescription therapies that must be monitored. For some it involves testosterone therapy for men or bioidentical hormone replacement for women, each with scheduled follow-up labs. For others it involves regenerative therapies such as PRP, PRF or shockwave treatment, or aesthetic care such as neurotoxins, fillers or skin resurfacing when the concern is how they look rather than how they feel. Any of these may or may not be appropriate for you, and all carry risks and limitations your provider will review.

Several of our programs are structured as memberships with a set cadence: baseline labs, a follow-up at three months and then every six months, with provider consultations in between. The structure exists because monitoring is not optional with these therapies. Appointments are at our office at 5944 Luther Lane, Suite 915, next to Hilton Park Cities, or the team can come to your home.

• Detailed history, goals and examination with an advanced practice provider
• Comprehensive bloodwork chosen for your situation
• A results review that explains what is and is not out of range
• Options discussed with their risks, limits and monitoring requirements
• Scheduled follow-up labs and consults if a program is started

What shapes the cost of this kind of care

We do not list prices in an article because programs are individual, but the drivers are consistent. The breadth of the initial lab panel is one. Whether a program involves prescription medication and how it is administered is another; weekly in-office injections and guided at-home dosing are structured differently. Memberships bundle visits, labs and consults on a schedule, which is priced differently from a single treatment. Aesthetic procedures are priced by the treatment and the area.

Many of these services are elective and not covered by insurance, so ask every clinic for a written breakdown before starting anything. We offer financing through CareCredit for those who want to spread the cost. The least expensive path is almost always a thorough evaluation first, because it avoids paying for treatments aimed at the wrong problem.

How to choose a clinic for hormones, weight or aesthetics

Ask who will treat you and what their licensure is. Ask whether labs are drawn before any therapy is prescribed and how often they are repeated. Ask what the plan is if your results do not support a treatment you came in asking about; a good clinic will tell you no. Ask how they handle side effects and who you call between visits. Ask whether they coordinate with your primary care provider.

Pay attention to how the clinic talks. Guarantees, before-and-after promises and pressure to buy a package on the first visit are warning signs. Education, candor about limits and a willingness to send you elsewhere when appropriate are the opposite. For aesthetic work, ask to see the provider's own results and ask about the specific product being used; for anything described as regenerative, ask what the evidence is and whether the product is FDA-approved for that use, because some, such as exosome products, are not.

• Licensed advanced practice providers, named and credentialed
• Labs before therapy and on a schedule afterward
• Willingness to decline a treatment your results do not support
• A clear plan for side effects and questions between visits
• Honest language about evidence, limits and what is not FDA-approved

The mistakes I see most often

Buying hormones, peptides or weight loss medication online without a prescription or monitoring is the most dangerous. Dose, purity and interactions are unknown, and no one is checking your blood. Starting a treatment because a friend had a good experience is the second; your labs and history are not theirs. Fixing one piece and ignoring the rest is the third: medication for weight while sleeping five hours and drinking nightly rarely delivers what people hope for.

The fourth is impatience with the evaluation. People arrive wanting a specific therapy and resent being asked for bloodwork. The fifth is the opposite: avoiding evaluation for years because the changes felt like something to be ashamed of. They are not. They are information, and information is where a good plan begins.

What happens when you contact us

You book online or call, and we schedule a consultation at the Dallas office or at your home. Bring your log, your medication list and any recent labs. Your provider takes a full history, discusses your goals, examines you and orders bloodwork. When results are back, you sit down together to review them and talk through options, including the option of doing nothing yet. If a program is right for you, you will know what it involves, what it costs, how it is monitored and what the limits are before you commit.

We see men and women from across Dallas, the Park Cities and the surrounding area, and what we want for each of them is the same thing you want: to understand what is going on and to make an informed choice about it, with a licensed provider who treats education as part of the care.
