Researchers from the University of Leipzig (Germany) found that women who were sexually abused in childhood had higher levels of ghrelin in their blood. The results of the work of scientists have been published magazine Translational Psychiatry (part of the Nature group).
Ghrelin is a hormone produced by the enteroendocrine cells of the gastrointestinal tract, primarily the stomach, and is often referred to as the “hunger hormone”. It increases food intake, so blood levels are highest before meals when a person is hungry. But when the body is under stress, ghrelin levels also rise.
In the study, the authors examined a sample of more than 1,000 participants (about 50% women). Numerous blood samples were taken from them (long before, several times before and after meals) and interviews were made about traumatic events, and body mass indexes were also calculated.
The results showed that women who experienced childhood abuse had higher levels of ghrelin in their blood. The men did not have this connection.
