The reasons for lack of sexual appetite can be very different. They can be on a psychological or physiological level in both men and women. The psychological aspect of the problem refers to changes related to the body that can lead to a lack of sexual desire. Diabetes leads to nerve damage, resulting in some loss of touch sensitivity. This is why 50% of diabetics suffer from erectile dysfunction and low testosterone levels – major causes of suppressed sexual function. Sex is essentially based on blood flow, and if the organ that controls blood circulation suffers, libido can also decrease. In this sense, any form of heart disease can affect sexual desire. Oral contraceptives are a drug that is famous for lowering libido in women. Other medications, such as statins, blood pressure medications, antidepressants, and even cold and flu medications can adversely affect sex drive. They interfere with the normal functioning of the body. NEWS_MORE_BOX Obesity is directly related to hormonal imbalance and decreased testosterone levels, which lower sexual desire in both sexes. Another problem is that increased body fat leads to a higher amount of sex-hormone-binding globulin. It is a natural chemical that binds to testosterone. This means that the amount of sex hormones is less, and sex life suffers. There is also evidence that obesity in young boys can lead to feelings of fatigue. In young girls, it can cause irregular menstrual cycles and thyroid problems.
