As men age, they may experience shifts in energy, mood, and health, often linked to declining testosterone levels. Dr. Aditya K. Sharma from Max Super Speciality Hospital explains that testosterone peaks in adolescence and early adulthood but drops by 1-2% annually after age 30. Symptoms of low testosterone include reduced muscle mass, increased body fat, decreased bone density, low libido, and mood changes. To manage low testosterone, consult a healthcare provider for a blood test. Effective treatments include lifestyle modifications such as regular exercise, a balanced diet, and stress management. Testosterone replacement therapy (TRT) is another option, involving synthetic testosterone supplements. Regular monitoring is crucial to check for potential side effects.
