The new study examined recent stretch marks and found that they had a higher density of hormone receptors than normal skin, and estrogen appeared to be the most concentrated. Since estrogen is involved in skin healing, that could represent the body’s attempt to heal the injured skin tissue. From the standpoint of steroid users, the greater number of estrogen receptors in stretch marks could also represent a defense against the high level of androgens, which interfere with skin healing. That latter part, however, is strictly speculation. What is known is that stretch marks have a higher density of hormone receptors than normal skin.
Gestational diabetes mellitus (GDM) resembles type 2 DM in several respects, involving a combination of relatively inadequate insulin secretion and responsiveness. It occurs in about 2–10% of all pregnancies and may improve or disappear after delivery.  However, after pregnancy approximately 5–10% of women with gestational diabetes are found to have diabetes mellitus, most commonly type 2.  Gestational diabetes is fully treatable, but requires careful medical supervision throughout the pregnancy. Management may include dietary changes, blood glucose monitoring, and in some cases, insulin may be required.
