What health problems are linked to high amounts of IGF-1?

IGF1 is a polypeptide that structurally is similar to human pro-insulin. IGF1 signaling plays a major role in controlling aging and lifespan. This factor is altered in obesity and many related diseases, including cardiovascular diseases and cancer.

What happens when IGF-1 levels get too high?

Increased secretion of GH and IGF-1 leads to abnormal glucose regulation, causing diabetes mellitus. A defect in lipid metabolism is also observed in some patients with acromegaly. The high level of IGF-1 in acromegaly is related to an increased risk of some cancers, particularly colon cancer and thyroid cancer.

What is IGF-1 signaling?

The insulin-like growth factor-1 receptor (IGF-1R) signaling pathway is a complex and tightly regulated network which is critical for cell proliferation, growth, and survival. IGF-1R is a potential therapeutic target for patients with many different malignancies.

What does IGF-1 do to the body?

IGF-1 is a hormone found naturally in your blood. Its main job is to manage the effects of growth hormone (GH) in your body. Normal IGF-1 and GH functions include tissue and bone growth. IGF-1 is formed in different tissues as a result of GH in the blood.

Is IGF-1 a growth hormone?

IGF-1 is a hormone that manages the effects of growth hormone (GH) in your body. Together, IGF-1 and GH promote normal growth of bones and tissues. GH levels in the blood fluctuate throughout the day depending on your diet and activity levels.

Does IGF-1 make you gain weight?

The weight gain that you will experience from the use of IGF-1 is not due to water weight. All your weight gain will be caused by actual muscle growth, which is a long-term effect.

Does TRT increase IGF-1?

Although testosterone (T) administration can increase insulin-like growth factor-I (IGF-I) when administered to hypogonadal men, no studies have examined whether this occurs in normal men.
