Definition

Minor disorders of pregnancy are common discomforts experienced during pregnancy due to normal physiological and hormonal changes. They are generally not life-threatening but may cause significant discomfort if not properly managed.

These disorders occur because of:

Increased progesterone levels causing relaxation of smooth muscles.
Increased estrogen production.
Enlarging uterus compressing surrounding organs.
Increased blood volume.
Changes in metabolism.
