Researchers at University of Adelaide Australia have found that weight loss of 5% can result in rapid reversal of sexual and urinary problems for obese men with type II diabetes.

Estimates of the prevalence of erectile dysfunction in men with diabetes vary widely, ranging from 20 to 75 percent. Men who have diabetes are two to three times more likely to have erectile dysfunction than men who do not have diabetes reports National Institute of Health.

Diabetes interferes with sexual stimuli controlled by the autonomic nerve signals. The normal sexual function occurs when the autonomic nerve signals increase the blood flow to the genitals and causing smooth muscles tissue to relax. Diabetes limits the sexual stimuli by damaging the autonomic nerves and blood vessels to the genitals. Autonomic nerves damaged by diabetes interfere with bladder and urinary control as well. Damaged autonomic nerve may send signals to the bladder at the wrong time, causing overactive bladder, frequency-urination, and sphincter muscles damage.

A study published in the Journal of Sexual Medicine, Researchers led by Professor Gary Witter has found that by providing meals with low fat, low carbohydrate, high protein diet, and decreasing the daily caloric intake to 600calories. Obese men with type II diabetes had a rapid positive change in sexual and urinary problems.

Results in a study of 31 Obese Diabetic men found that, a modest weight loss of 5%, resulted in a rapid reversal of sexual and urinary problem, within 8 weeks, and the improvement continued out to 12 months.

"The evidence that improvement can be achieved by modest weight loss, in particular when a diet is of high nutritional quality, is of public health significance in framing public health messages that resonate with men." said Witter
