What do the results mean? If your child’s results show lower than normal levels of IGF-1, it probably means he or she has a GH deficiency or insensitivity to GH. In a child, this may be caused by a genetic disorder or brain disease. Your child may benefit from treatment with GH supplementation.
What causes low IGF levels?
Causes and Risk Factors
A lack of growth hormone is usually caused by damage to the pituitary gland or the hypothalamus, a part of the brain that controls the pituitary gland. The damage may be due to a tumor; to surgery or radiation used to treat the tumor; or to problems with the blood supply to the pituitary gland.
How can I increase my IGF-1 levels?
Conclusion: Supplementation with selenium and coenzyme Q10 over four years resulted in increased levels of IGF-1 and the postprandial IGFBP-1, and an increase in the age-corrected IGF-1 SD score, compared with placebo.
What affects IGF-1 levels?
Factors that are known to cause variation in the levels of growth hormone (GH) and IGF-1 in the circulation include: insulin levels, genetic make-up, the time of day, age, sex, exercise status, stress levels, nutrition level and body mass index (BMI), disease state, ethnicity, estrogen status and xenobiotic intake.
What is the normal level of IGF-1?
The median serum IGF-I level was 374.1 ng/ml at the age of 18. The serum IGF-I level decreased to 180.1 ng/ml at the age of 35–39, which is 48.1% of that at age 18, and further decreased to 92.7 ng/ml at ages older than 70, which is approximately 24.8% of that at age 18.
Is IGF-1 GOOD OR BAD?
People may also misuse or abuse IGF-1. The side effects of IGF-1 may be similar to those of other growth hormones. These include overgrowth of body tissues, known as acromegaly, and damage to the joints, liver, and heart. IGF-1 can cause your blood glucose levels to drop.
Does IGF-1 increase growth hormone?
Conclusion—IGF-1 is an important growth hormone, mediating the protein anabolic and linear growth promoting effect of pituitary GH. It has a GH independent growth stimulating effect, which with respect to cartilage cells is possibly optimised by the synergistic action with GH.
Does IGF-1 make you lose weight?
IGF-1 alone won’t result in weight loss but can help in lean muscle development. However, incorporating IGF-1 alongside a balanced diet together with increased cardiovascular and resistance workouts will result in faster weight loss over time. IGF-1 is not promoted as a weight loss tool.
What are the benefits of IGF-1?
WHAT MAY BE THE BENEFITS OF IGF-1/LR3
- Muscle hypertrophy effects.

Does IGF-1 raise testosterone?
A relationship between GH, IGF-1 and testosterone has previously been demonstrated. Curiously, no significant correlation is demonstrated between serum IGF-1 and testosterone levels or between testosterone levels and SHIM/EPIC scores in our work.
Does IGF-1 inhibit growth hormone?
The hypothalamic growth hormone (GH)-releasing hormone (GHRH) promotes non-rapid eye movement sleep (NREMS). Insulin-like growth factor-1 (IGF-1) acts as a negative feedback in the somatotropic axis inhibiting GHRH and stimulating somatostatin.
Can IGF-1 cause diabetes?
IGF-I has an almost 50% amino acid sequence homology with insulin and elicits nearly the same hypoglycemic response. Studies showed that low and high IGF-I levels are related to impaired glucose tolerance and to a higher risk of type 2 diabetes.
What does IGF-1 LC MS test for?
This test is used to assess growth disorders in symptomatic children and adults and to monitor response to therapy.
What is the IGF-1 blood test?
A somatomedin C test, also called an insulin-like growth factor-1 (or IGF-1) test, helps doctors evaluate whether a person is producing a normal amount of human growth hormone (hGH, or somatotropin).
