Are ghrelin levels related to obesity?

Ghrelin is a hormone found primarily in the stomach, although it exists in other areas of the body. Over the past few years, Ghrelin's levels in the human body have gained a lot of attention because the connection between the hormone and the control of hunger has been found. When examining Ghrelin levels, scientists have found that hormone increases the feelings of hunger as it increases in the body. In addition, high levels of ghrelin have been found to suppress the amount of fat used by fat tissue. This means that those who have high ghrelin levels in their bodies will not only feel starver than those with a low level, but can also burn fat more slowly. In thinner individuals, however, it seems that Ghrelin levels grow between midnight and dawn when most people sleep. Therefore, thinner individuals are most likely to sleep in this period Ized hunger. This has led scientists to believe that obese individuals may have a problem with their circulatory system.

In the related remark, further research has indicated that lack of sleep can also cause obesity. This seems to be related to an increase in appetite, which can be stimulated by elevated levels of ghrelin. In fact, the lack of sleep seems to cause the body to produce more ghrelin. Ghrelin not only stimulates appetite, but also suppresses the creation of gluten, which helps to suppress appetite.

also found other relationships between levels and Ghrelin levels. One study found that individuals undergoing surgery of the stomach have reduced ghrelin levels. On the other hand, individuals suffering from anorexia nervosa tend to have higher levels of ghrelin.

Despite the research of Ghrelin levels and many interests of findings, scientists are still not sure of the accurate relationship between ghrelin levels and obesity. Specifically, it is not clear whether high levels of ghrelin cause obesity or whether obesity causes increased ghrelin levels.
