Low sexual desire can have many causes, such as stress, relationship issues, hormonal imbalance, fatigue, or medical conditions, so improving libido usually requires a combination of lifestyle and emotional care rather than a single medicine. Focus on regular exercise, good sleep, a balanced diet, reducing stress (through relaxation, yoga, or meditation), and open communication with your partner, as these can significantly improve desire. Avoid smoking and excess alcohol, and limit overuse of pornography if relevant. If the problem persists, it is important to check for underlying issues like Depression, thyroid problems, or low testosterone (in men), which may need medical treatment. Counselling or sex therapy can also be very helpful. Medications are used only in selected cases under a doctor's guidance, so it is best to seek proper evaluation rather than self-medicating.
