Hello, You are suffering from ED (erectile dysfunction). You are advised to maintain healthy weight if overweight. Improve your general health, get checked your hormone levels so that it can be treated at the earliest. Low testosterone and lack of proper sleep are the main factors that cause a weak erection. ED is triggered due to heavy smoking, alcohol intake and taking recreational drugs / medicines. Be careful what medicines you have been taking, do not take overdoses. Get examined by a GP, get required tests and investigations done so that the underlying medical conditions (like prostrate problem, neurological problems, heart disease, diabetes, etc.) may be causing you symptoms can be treated. You can get connected to a counsellor to come out of any psychological problem like depression, anxiety, fear of proper sexual performance, relationship problem, low self-esteem, etc. Kegel exercises, knee fallouts, supine foot raises, pelvic curls, cycling, running, are helpful & improve weak erections. Take balance home-made food rich in minerals and high in protein. Medicines like Sildenafil or Tadalafil, etc., are helpful. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
