7 Signs Your Testosterone Is Low (And What You Can Do About It)

If you’re a man over 40 and not feeling like yourself lately—more tired, less motivated, and struggling to keep up in the gym—you could be experiencing symptoms of low testosterone.

At Nuesana Health & Wellness in Bonita Springs, we see this every day. Men who once felt sharp, strong, and energized come to us wondering why their edge is slipping. In many cases, the culprit is low testosterone.

Here are the top 7 signs your testosterone may be low—plus what you can do about it.

1. Low Energy and Chronic Fatigue

Even with a full night’s sleep, men with low testosterone often wake up feeling drained. If you rely on caffeine to get through the day or hit a wall mid-afternoon, your hormone levels could be off.

➡️ Nuesana Tip: We offer same-day lab testing to check your T levels and create a personalized recovery plan.

2. Loss of Muscle Mass and Strength

Testosterone is essential for building and maintaining lean muscle. If you’ve noticed that your workouts aren’t as effective or you’re losing muscle despite training, low T may be a factor.

➡️ Pro Insight: TRT combined with strength training can help you rebuild muscle faster—especially when supervised by our medical team.

3. Increased Body Fat—Especially Around the Belly

A drop in testosterone can shift your body composition, causing stubborn fat to accumulate around the midsection. It’s not just cosmetic—it’s a sign your metabolism is slowing down.

➡️ Nuesana Insight: Many of our clients start seeing changes in body fat within 30 to 60 days of starting testosterone therapy.

4. Low Libido or Sexual Performance Issues

A sharp decline in sex drive or performance can be one of the most frustrating symptoms of low testosterone. It’s also one of the most common.

➡️ The Good News: With proper hormone optimization, many men experience a resurgence in libido, confidence, and performance.

5. Mood Swings, Anxiety, or Depression

Testosterone plays a powerful role in regulating mood. Low levels have been linked to irritability, lack of motivation, and even depression.

➡️ At Nuesana: We take a whole-body approach to men’s health, looking at hormones, nutrition, sleep, and stress.

6. Brain Fog and Poor Focus

Struggling to concentrate, remember details, or stay mentally sharp? Low T might be impacting your cognitive function.

➡️ What to Do: Don’t just write it off as aging. A simple lab test can reveal if your hormones are affecting your mental clarity.

7. Trouble Sleeping

Low testosterone is often linked with poor sleep quality and even sleep apnea. This creates a vicious cycle—less sleep, less T, and worse performance.

➡️ Optimize Recovery: We’ll help you dial in sleep, hormones, and recovery so your body can restore naturally.
