1 Ghrelin is a fast-acting hormone that plays a vital role in meal initiation and contributes to weight gain. 2  Leptin mediates long-term regulation of energy balance and suppresses food intake, thereby inducing weight loss.  Both hormones can be controlled naturally, primarily though exercise and stress management.
Surgical retractors. A retractor is a surgical instrument with which a surgeon can either actively separate the edges of a surgical incision or wound, or can hold back underlying organs and tissues, so that body parts under the incision may be accessed. The two are each available in many shapes, sizes, and styles.
A D&C, also known as dilation and curettage, is a surgical procedure often performed after a first-trimester miscarriage. In a D&C, dilation refers to opening the cervix; curettage refers to removing the contents of the uterus. Curettage may be performed by scraping the uterine wall with a curette instrument or by a suction curettage (also called vacuum aspiration).
