The disappearance of morning erection does not mean that there is a problem with sexual function, there is no need to worry too much. Factors such as lack of sleep, stressful work, excessive fatigue, excessive smoking, alcohol abuse, excessive intercourse and other bad habits can all affect morning erections. Even a normal person may not have a morning erection every day, which is not a big deal. The real problem is the erection during deep sleep, which is usually not disturbed by psychological factors and can give a more realistic picture of sexual function. In addition, many kinds of medications such as hypertension drugs, anti-tumor drugs, glucose-lowering drugs, and sedative drugs can cause morning erections to decrease or disappear. It is common for men with certain clinical conditions to have diminished or absent morning erections, and when they are cured, the morning erection is restored. So when do I need to go to the hospital to get checked? If the morning erection never returns and is accompanied by symptoms such as low libido and difficulty in getting an erection on a daily basis, it is time to be alert and go to the hospital for a checkup. In addition, if the morning erection disappears for a long time, it may also indicate the occurrence of high blood pressure, heart disease, diabetes and other diseases.
