Because the slimming clothes tightly wrap the abdomen and oppress the organs such as kidney, spleen, liver, stomach and intestine in the abdominal cavity, the internal organs and their nervous system are in a state of tension for a long time. This state affects intestinal peristalsis, easily reduces gastrointestinal function and weakens digestive system, thus causing constipation. At the same time, if women are constipated for a long time, their faces will be ugly and prone to spots. Can cause gynecological diseases, because tight underwear makes vulva secretion accumulate, which can't be distributed in a humid and sultry environment, which stimulates vulva and causes vulvitis. Moreover, if the slimming clothes are too tight, dermatitis and bacterial reproduction will be caused by the wear of thigh skin, and retrograde infection will induce vaginitis, pelvic inflammatory disease and urinary tract infection. In addition, wearing slimming clothes will directly affect the blood circulation system. For women who have never given birth, poor pelvic blood circulation will cause pelvic congestion, uterine dysplasia and other diseases, and severe cases will lead to infertility.
