The pelvic floor muscles may also be loose even if you have not given birth. In most women, pelvic floor muscle relaxation is caused by pregnancy and childbirth, which results in pelvic muscle, fascia, and ligament overstretching and damage, resulting in the symptoms of pelvic floor muscle relaxation. In addition to pregnancy and childbirth, pelvic floor muscle relaxation can also be caused by congenital pelvic developmental abnormalities, aging, miscarriage or induced abortion, prolonged coughing or constipation, excessive physical labor, and too frequent sexual intercourse. Pelvic floor muscle relaxation can also occur in women who have not had children, and patients should consult a doctor to identify the cause of the problem and treat it. The cause of the problem can be identified and treated by doing anal contraction exercises or pelvic floor muscle rehabilitation training, and in severe cases, pelvic floor muscle repair surgery can be used. Patients with symptoms of pelvic floor muscle relaxation should go to a regular hospital in time, under the guidance of the doctor to adjust or treatment, so as not to delay the condition.
