Leading to increased permeability to proteins

Resulting in their loss through the urine.

This leads to hypoalbuminemia, edema

Aand other complications associated with nephrotic syndrome.

Then the anterior-posterior diameter, the most common type of pelvis is the gynaecoid pelvis.

This type of pelvis is considered the typical female pelvis

And is most favorable for childbirth due to its rounded shape and wide dimensions.
