Reclaim Your Energy and Confidence with Dr. Manish Sahni in Sun City
At Centra Internal Medicine, we understand the important role that hormones like testosterone play in your overall health and well-being. Testosterone Replacement Therapy (TRT) is one of the treatment options we offer to our patients who have been diagnosed with low testosterone levels, a condition that can significantly impact muscle strength, energy, and quality of life.
Testosterone is a vital hormone for the development and maintenance of muscle mass. It helps stimulate protein synthesis within muscle cells, which is essential for muscle repair and growth—particularly after exercise or injury. For our patients at Centra Internal Medicine, restoring testosterone levels to a healthy range through TRT can lead to noticeable improvements in muscle strength and an increase in lean body mass.
In addition to supporting muscle health, TRT can enhance physical performance by increasing energy levels and reducing fatigue. This often enables our patients to participate more fully in regular physical activity and strength training, which are key components of maintaining long-term health. Testosterone also supports the production of red blood cells, improving oxygen delivery to muscles during exercise and helping to boost endurance and stamina.
Maintaining optimal testosterone levels can also contribute to a decrease in body fat, which further enhances muscle definition and overall functional movement. Our team specializes in identifying and treating hormone imbalances, ensuring that our patients receive personalized care tailored to their unique needs.
If you are experiencing symptoms of low testosterone—such as decreased muscle strength, fatigue, or difficulty maintaining muscle mass—our experienced providers can evaluate your hormone levels and discuss whether Testosterone Replacement Therapy is right for you. Our goal is to help you regain your energy, optimize your physical performance, and improve your overall quality of life.
At Centra Internal Medicine, we understand that symptoms such as reduced mental focus and diminished motivation can significantly impact your quality of life. For some individuals, these symptoms may be related to low testosterone levels—a condition known as hypogonadism. Testosterone is a hormone that plays a critical role in mood regulation, cognitive function, and overall energy levels.
Our team provides comprehensive evaluation for men experiencing symptoms of low testosterone. Research suggests that men diagnosed with clinically low testosterone may notice improvements in concentration, motivation, and general well-being after starting testosterone replacement therapy. However, it’s important to recognize that the effects of testosterone therapy can vary from person to person. While some patients may experience enhanced mental clarity and drive, others might see only modest changes.
It is also important to note that testosterone therapy is not appropriate for individuals with normal hormone levels, and unnecessary supplementation can pose significant health risks. Factors such as psychological health, lifestyle, and other medical conditions can also influence mental focus and motivation.
If you are concerned about symptoms of low testosterone, our providers will perform a thorough assessment—including a detailed discussion of your symptoms, laboratory testing, and a review of your overall health—before making any treatment recommendations. We strongly advise against self-medicating or starting testosterone therapy without medical supervision, as this can lead to adverse health effects.
At Centra Internal Medicine, we understand that ongoing monitoring is crucial to the safety and effectiveness of testosterone replacement therapy (TRT). That’s why our providers recommend a structured follow-up schedule for all patients undergoing TRT.
Initial Follow-Up:
After starting TRT, we typically schedule your first follow-up visit within three months. During this appointment, your provider will assess your response to treatment, monitor for any side effects, and check your testosterone levels. This allows us to make any necessary adjustments to your dosage and ensure you are tolerating the therapy well.
Ongoing Monitoring:
For the first year of TRT, follow-up visits are generally recommended every three to six months. At each visit, our team will continue to monitor your hormone levels, blood count, prostate health, and overall well-being. These regular check-ins help us maintain optimal treatment outcomes and promptly address any concerns.
Long-Term Care:
Once your treatment has stabilized, and both you and your provider are confident in your response and lab results, follow-up visits may be spaced out to every six to twelve months. However, we tailor your follow-up schedule based on your individual health factors, the type of testosterone therapy used, and whether you experience any side effects or complications.
Patient Communication:
Our team encourages you to communicate any new symptoms or concerns between visits. Following your provider’s recommendations and staying in touch with us ensures you receive safe, effective, and personalized long-term TRT management.
