progesterone
- softens cartilage on joints -vasodilates vessels to accomodate increased volume -relaxes smooth broncioles which leads to hyperventilation -smooth muscle relaxation delays gastric emptying time and motility -decreases esophageal tone and acid reflux -dilate ureters, urethra, and bladder increasing risk of UTI -hydronephrosis and increased intrauterine pressure - thyroid enlargement
estrogen and progesterone
-hyperpigmentation -affect plasma renin activity and aldosterone to increase sodium retention which increases water retention -modify metabolism and excretion of bilirubin
