Which Hormones Decline With Age?
Hormonal decline is a natural part of aging, but the speed and severity vary widely between individuals. The most commonly affected hormones include:
Testosterone — In men, testosterone peaks in the early 20s and declines roughly 1–2% per year after age 30. In women, testosterone also plays a role in energy, libido, and muscle maintenance, and declines alongside estrogen.
Estrogen and Progesterone — Women experience a dramatic decline in these hormones during perimenopause and menopause, typically beginning in the 40s. The drop in estrogen is linked to hot flashes, vaginal dryness, bone loss, and cardiovascular changes.
Thyroid Hormones — Subclinical hypothyroidism is underdiagnosed and can cause fatigue, weight gain, and cold sensitivity even when standard labs come back 'normal.'
DHEA — A precursor hormone produced by the adrenal glands, DHEA declines steadily after age 25 and contributes to aging-related fatigue and immune changes.
Growth Hormone — Declines with age and is linked to body composition changes, reduced muscle mass, and impaired recovery.
Common Symptoms of Hormone Imbalance
Many people dismiss hormone imbalance symptoms as 'just getting older.' But these symptoms often have a measurable, treatable cause:
• Persistent fatigue despite adequate sleep
• Unexplained weight gain, especially around the midsection
• Low libido or sexual dysfunction
• Brain fog, difficulty concentrating, or memory lapses
• Mood swings, anxiety, or depression
• Poor sleep quality or insomnia
• Loss of muscle mass or strength
• Thinning hair or dry skin
• Hot flashes or night sweats (women)
• Erectile dysfunction (men)
If you're experiencing three or more of these symptoms, a comprehensive hormone panel is a logical first step.
Who Is a Good Candidate for HRT?
HRT is not one-size-fits-all. A thorough evaluation — including labs, a medical history review, and a conversation about your goals — helps determine whether HRT makes sense for you.
Good candidates typically include men and women aged 35–70 who are experiencing symptoms of hormone decline, have labs confirming suboptimal levels, and have no contraindications such as certain hormone-sensitive cancers or active blood clots.
Bioidentical hormones — which are structurally identical to the hormones your body naturally produces — are increasingly preferred for their compatibility and customizability. These can be delivered via pellets, injections, creams, or oral medications depending on which hormones are being addressed.
At Peak Medical Wellness in Fort Collins, every HRT patient receives a personalized protocol based on their specific labs and symptoms — not a generic template.
What Does the Process Look Like?
Starting HRT at a provider-directed wellness clinic typically follows this path:
1. Comprehensive Lab Panel — We test total and free testosterone, estradiol, progesterone, SHBG, thyroid panel, DHEA-S, cortisol, and more depending on your symptoms.
2. Provider Consultation — A licensed provider reviews your labs alongside your symptoms, health history, and goals to determine the right protocol.
3. Starting Your Protocol — You'll begin with an evidence-based starting dose. Delivery methods vary: pellets last 3–6 months, injections are weekly or biweekly, and topical creams are applied daily.
4. Follow-Up and Optimization — Labs are rechecked at 6–8 weeks to assess levels and adjust dosing. Ongoing monitoring ensures you stay in the optimal range.
HRT is not a one-time fix — it's an ongoing relationship with your provider to keep you feeling your best as your needs evolve.
Frequently Asked Questions
What is hormone replacement therapy (HRT)?
HRT restores hormones that have declined or fallen out of balance — most often estrogen and progesterone in women and testosterone in men, sometimes thyroid. The goal is relieving symptoms like low energy, poor sleep, mood changes, low libido, and the effects of menopause, with dosing guided by your labs and symptoms.
What are the signs you might need hormone therapy?
Common signs include persistent fatigue, low libido, mood changes or irritability, brain fog, poor sleep, weight changes, and — in women — hot flashes, night sweats, and irregular cycles. Because these overlap with other conditions, the way to know is lab testing interpreted alongside your symptoms.
What's the best age to start HRT, and is it ever too late?
For women, the most favorable benefit-risk window is generally within about 10 years of menopause or before age 60, when symptoms are often most disruptive. Starting later can still be appropriate but is individualized. For men, there's no set age — testosterone therapy is based on symptoms and labs. Your provider helps you weigh timing.
How long can a woman stay on hormone therapy?
There's no fixed limit. Many women use HRT through the menopause transition; some continue longer for ongoing symptom control and bone protection. The decision is revisited periodically with your provider, weighing your symptoms, benefits, and personal risk factors.
What are the downsides or risks of HRT?
Like any medical treatment, HRT has risks that depend on your age, health history, the hormone type, and delivery method. Modern, individualized HRT — especially started near menopause — has a favorable profile for most healthy candidates, but it isn't right for everyone. Your provider reviews your history and monitors you to keep treatment as safe as possible.
Who should avoid hormone therapy?
HRT generally isn't used in people with a history of hormone-sensitive cancers (like certain breast cancers), unexplained vaginal bleeding, blood clots, or significant liver or cardiovascular disease, among others. A thorough history and labs help your provider determine whether it's safe for you.
What happens when you start HRT?
You start with lab work and a symptom review, then a personalized dose. Many people notice improvements in sleep, mood, and energy within the first several weeks, with fuller effects on libido and body composition over a few months. Follow-up labs let your provider fine-tune the dose.
What are the alternatives to HRT?
Lifestyle steps — sleep, strength training, stress management, nutrition, weight management — can meaningfully help symptoms and support hormone health, and there are non-hormonal medications for specific symptoms like hot flashes. For many people the best results combine lifestyle changes with appropriately dosed therapy; your provider can lay out the options.
Is bioidentical hormone therapy safer than synthetic?
Bioidentical hormones are structurally identical to the ones your body makes, which is why many patients and providers prefer them. But bioidentical doesn't automatically mean risk-free — safety still depends on dose, delivery method, your health history, and monitoring. A provider helps you choose the right formulation.
