Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
It will contract midline with the umbilicus. It begins its contractions and by twelve hours after the birth it can be felt to be at the level of the umbilicus. [9] The uterus changes in size from one kilogram to 60-80 grams in the space of six weeks. After birth, the fundus contracts downward into the pelvis one centimeter each day.
Gallstones can vary in size and shape from as small as a grain of sand to as large as a golf ball. [39] The gallbladder may contain a single large stone or many smaller ones. Pseudoliths, sometimes referred to as sludge, are thick secretions that may be present within the gallbladder, either alone or in conjunction with fully formed gallstones.

These postural compensations culminate in an increased load on both lumbar spinal musculature and the sacroiliac ligaments, manifesting as low back pain and/or pelvic girdle pain. [ 14 ]

[1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Studies show that all of these issues can arise from lying in the supine position during late pregnancy, which can cause compression and obstruction of the inferior vena cava by the uterus. [1] Symptoms of late pregnancy inferior vena cava syndrome consist of intense pain in the right hand side, muscle twitching, hypotension , and fluid retention.
A small pelvis of the mother can be a result of many factors. Risk factors for a small pelvis include malnutrition and a lack of exposure to sunlight causing vitamin D deficiency. [3] A deficiency in calcium can also result in a small pelvis as the structures of the pelvic bones will be weak due to the lack of calcium. [11]
It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number. [2] Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in the case of the hormonally induced proliferation and enlargement of the cells of the uterus during pregnancy .
