Igf 1 Somatomedin C
When igf-1 is shown as high at one lab so doctor runs test at other labs until normal result obtained, which is then relied on, are any of the results valid?
They aren't: There aren't any natural igf-1 supplements. Igf-1 is made in your body. It is also available by injection from a physician, not it is really in any supplement you can buy at the store or on the internet. Even if it were, it wouldn't work and would be broken down in you stomach. ...Read more
Growth: IGF-1 is one of the main "growth hormones" and is stimulated by pituitary growth hormone. During adolescence, the levels of IGF-1 are higher than at other times. A very high IGF-1 can occur due to acromegaly, which is a pituitary tumor making excess GH, but this is very rare. A pediatric endocrinologist is the expert on this. ...Read more
Don't waste money: The IGF-1 products sold in health stores and on the internet as anti-aging agents have not been clinical tested and are unlikely to have any real benefit so it probably makes no difference how you take them. My advice is not to waste you money on them but try eating healthier and getting more exercise ...Read more

No GH excess: Hi. In our lab, that IGF-1 would be within normal limits for a 43 yo woman, so we have no evidence of growth hormone excess. However, the BMI is 36.4, diagnostic of obesity. The height is stated as "1.82 cm", but I strongly suspect you mean 1.82 m or 182 cm. This is taller than the average woman, but the IGF-1 suggests no GH excess. ...Read moreSee 1 more doctor answer
Probably not: The igf level is in the low normal range for age, and highly dependent upon time of day and other factors. Don't know why your doc would have been drawing an igf level at your age without having other abnormal lab prior to checking igf. Ask your doctor why. ...Read more
GH measurement: Gh levels fluctuate considerably throughout the day, often being high during the night, and very low other times of the day, which makes a single measurement unreliable. Igf1 is more stable. Adolescence is a time of many normal hormone fluctuations. There are diseases associated with very high gh/igf1 (eg. Acromegaly) but are rare. ...Read more
When igf-1 is high and gh are normal rule out the possibility of Acromegaly? Or get more complicated the Diagnosis?
Unlikely: Acromegaly as a result of excessive GH is extremely rare and symptoms are not straight forward but you can look them up. The IGF-1 is a good screening test for GH excess but if it was only mildly elevated the normal GH would be reassuring. After you read up, please discuss with the doctor who ordered the tests because it can be complicated ...Read more
