Low testosterone, also known as hypogonadism, affects millions of men and can significantly impact quality of life. Recognizing the signs and seeking appropriate treatment can help restore energy, mood, and overall well-being.
Signs and Symptoms
Common symptoms of low testosterone include decreased libido, fatigue, reduced muscle mass, increased body fat, mood changes, difficulty concentrating, and decreased bone density. These symptoms can develop gradually, making them easy to dismiss as normal aging.
Diagnosis and Treatment
Diagnosis typically involves evaluating symptoms and medical history to assess testosterone levels. Treatment options include testosterone replacement therapy (TRT) in various forms such as injections, gels, patches, or pellets. Lifestyle modifications, including exercise and weight management, can also help support healthy testosterone levels.
