Your IGF-1 is within the reference range for your age group, indicating appropriate growth hormone activity and metabolic support.
Very low IGF-1 indicates very low growth hormone activity — causing muscle wasting, bone loss, poor wound healing, fatigue, and impaired immune function in adults. In children, it may contribute to growth failure.
Seek urgent endocrinology evaluation. Growth hormone deficiency workup including stimulation tests is needed. noticeable malnutrition must also be excluded.
IGF-1: {{value}} {{unit}} — very low (ref: {{low}}–{{high}})Low IGF-1 is associated with reduced muscle mass, increased body fat, poor exercise recovery, fatigue, and reduced bone density. Causes include growth hormone deficiency, malnutrition, liver disease (IGF-1 is made in the liver), hypothyroidism, and poorly controlled diabetes.
Investigate with growth hormone stimulation testing if clinically suspected. Check liver function, thyroid, and nutritional status.
IGF-1: {{value}} {{unit}} — below reference range (ref: {{low}}–{{high}})Borderline low IGF-1 can contribute to reduced muscle-building capacity, slower recovery from exercise, and suboptimal bone density over time.
Optimize protein intake, sleep quality, and regular resistance exercise — all of which stimulate GH and IGF-1 production. Discuss with your doctor if symptoms are significant.
IGF-1: {{value}} {{unit}} — borderline lowYour IGF-1 is within the reference range for your age group, indicating appropriate growth hormone activity and metabolic support.
No action needed.
IGF-1: {{value}} {{unit}} — within reference rangeYour IGF-1 is in the healthy upper range, providing strong support for muscle protein synthesis, bone density, wound healing, and metabolic health.
Excellent result. Continue resistance training and quality protein intake to maintain this level.
IGF-1: {{value}} {{unit}} — optimalBorderline high IGF-1 can reflect naturally high GH activity, recent intense exercise, high protein intake, or the natural elevation of puberty. It is generally favorable in these contexts.
No action needed in most cases. In adults with unexplained borderline elevation, discuss with your doctor.
IGF-1: {{value}} {{unit}} — borderline highElevated IGF-1 in an adult can indicate acromegaly — a condition of excess growth hormone, usually from a pituitary adenoma. This may contribute to enlargement of the hands, feet, and facial features, and noticeably increases cardiovascular and cancer risk. Some cancer types also secrete IGF-1.
See your doctor for growth hormone suppression testing and pituitary imaging. Acromegaly is serious but very treatable when found early.
IGF-1: {{value}} {{unit}} — above reference range (ref: {{low}}–{{high}})Very high IGF-1 strongly suggests active acromegaly or gigantism (in children) from a growth hormone-secreting pituitary tumor. At this level, significant organ damage is likely — heart, joints, vision, and metabolic complications are all affected.
Seek urgent endocrinology evaluation. Pituitary MRI and growth hormone suppression testing are urgently needed. This is an active endocrine tumor until proven otherwise.
