The 1 kilobase IGF-I mRNA species exhibited a 43% decrease after 24 h of fasting, a 76% decrease after 48 h of fasting, and an 82% decrease after 72 h of fasting. Hepatic GH receptor mRNA also decreased in fasting rats. My blood tests also revealed that the major inhibitor of IGF-1, which is called IGFBP-1, was significantly up during the fasting period.

Insulin-like growth factor 1 (IGF-1) is a derivative of human growth hormone (GH) that induces skeletal muscle growth and bone remodeling. It is also involved in the regulation of cell development and differentiation. Its concentration in the blood can be examined to understand health concerns that could indicate an IGF-1 deficiency.

A test for insulin-like growth factor-1 (IGF-1) may be used to help: Identify growth hormone (GH) deficiency; it is not diagnostic of a GH deficiency but may be requested along with GH stimulation tests to offer additional information Detect GH excess in suspected cases of acromegaly or gigantismFree IGF-I and IGFBP-1 levels were also affected by fasting status while total IGF-I and IGFBP-3 levels remained stable. Adipokines levels were largely insensitive to fasting status and delays in blood sample processing. Testing schedules may vary.
