The uterus (womb) increases by 20x in weight by the end of pregnancy. Additionally, the bottom of the pelvis drops as much as 2.5 cm. This combination results in weakness of the muscles that support the organs in the pelvis and decreases the effectiveness of the muscles of the pelvis as it relates to preventing the leakage of urine.
During pregnancy, there is also a systemic decrease in ligament strength due to hormone changes; hormone levels remain elevated for 3-5 months after pregnancy and longer if the mother is nursing. Laxity of the ligament that supports the bottom of the pelvis further weakens the muscles that support the pelvis.
When you rediscover your M.U.S.I.C. , that means restoring urinary continence.
