Renal insufficiency in men may not affect sexual function in the short term or if the condition is relatively mild. If the onset time is long or the condition is more serious, it may have an effect on sexual function. 1. Does not affect sexual function: If renal insufficiency is relatively mild or has a relatively short onset, it will not affect the level of human sex hormone secretion, and thus has little effect on sexual function. However, symptoms such as fatigue, poor appetite and oliguria may occur. 2. Impact on sexual function: If the onset of renal insufficiency is long and the condition is serious, endocrine system disorders will occur, and the level of sex hormones will decrease, thus affecting the sexual function. If you have renal insufficiency, it is recommended that you consult a doctor in a timely manner and give active treatment under the guidance of the doctor to prevent affecting the sexual function. In daily life, we should pay attention to prevent cold and flu, do not stay up late and overwork to avoid kidney damage. In terms of diet, we should pay attention to some light, low-salt and low-fat, and eat less greasy and fried food.
