The importance of testosterone
Recent research has shown a link between testosterone levels and men’s health. When testosterone levels are low, an array of diseases and health problems are often present.
According to research conducted in 2,100 men, aged over 45 years, it was found low testosterone levels are more likely in men who are overweight, or who have diabetes or high blood pressure.
But we cannot jump to the conclusion that low testosterone levels are the cause of those health problems. It could be the other way around — health problems may be the cause of low testosterone levels.
Testosterone helps our body tissues absorb sugar. Men with low testosterone levels, therefore, can have low insulin levels, which leads to diabetes.
About half of men with diabetes have low testosterone levels. One study suggested that testosterone injections can help improve insulin levels in men. Yet continued use is bad for the heart.
Obesity and testosterone levels are also related. Overweight men often have low testosterone levels, and vice versa. This is because fat cells convert testosterone into oestrogen, causing the levels to drop. Obesity also decreases the amount of a globulin proteins, which in turn lowers testosterone levels. Exercising helps improve testosterone levels, while supplementary testosterone can to a certain extent treat obesity.
Men with low testosterone levels are more prone to diseases related to metabolic systems, such as high cholesterol and high blood sugar. Supplementary testosterone was found to help improve levels of blood sugar and reduce obesity. It is unknown whether long-term use will cause any adverse effects.
It is believed that abnormal testosterone levels can increase the risk for heart disease in men. This includes high testosterone levels. Isn’t that confusing? Both high and low testosterone levels are bad for the heart.
Maintaining healthy testosterone levels is good for your health. It’s all about finding and maintaining the right balance. Low testosterone levels are associated with many other health conditions, such as depression and sexual performance.
A study of 4,000 men aged more than 70 years showed that those with low testosterone levels are twice as likely to be depressed. Erectile dysfunction is also caused by low testosterone levels. The relation between high blood pressure and low testosterone levels is a little more complicated, as high testosterone levels also causes high blood pressure.
Another interesting question is whether low testosterone levels can worsen existing health conditions. More studies are needed before coming to a conclusion. What we know now is that hormone replacement is not 100% guaranteed. Staying healthy through a good diet and adequate exercise is still the safest choice.
