Insulin – what do your numbers mean?
Have you had your insulin level measured and are unsure what the numbers mean? Here's a clear explanation of the normal range, what a high or low level might mean, and when it makes sense to get tested.
What is the normal range for Insulin?
What is the normal range for Insulin?
The normal range for insulin in the blood varies depending on the laboratory's measurement methods and the reference population. Generally, fasting insulin values are between 5-69 pmol/L according to Steno Diabetes Center and under 83 pmol/L according to Unilabs Danmark. In pregnant women, levels may be higher, and women taking birth control pills or estrogen therapy may also have elevated values. It is important to note that insulin measurements can be affected by factors such as food intake and fasting, which is why samples are often taken after fasting. Variations can also occur depending on age and gender, but these are rarely specified in standard measurements. Being close to the reference values can indicate incipient insulin resistance or other metabolic disturbances, and further investigations may be necessary.
What does a low level mean?
A low insulin level can indicate type 1 diabetes, where the body does not produce enough insulin. It can also be associated with pituitary insufficiency or prolonged fasting. Symptoms of low insulin include fatigue, weight loss, increased thirst, and frequent urination. Individuals with low insulin may experience high blood sugar, as glucose is not efficiently transported into cells. Particularly vulnerable groups include individuals with autoimmune diseases or those who have undergone pancreatic surgery. Treatment often involves insulin therapy and close monitoring of blood sugar levels. It is important to seek medical help for proper diagnosis and treatment.
What does a high level mean?
A high insulin level, also known as hyperinsulinemia, can be a sign of insulin resistance, often associated with type 2 diabetes, metabolic syndrome, or obesity. It can also be caused by a rare condition such as insulinoma, a tumor in the pancreas. Symptoms may include weight gain, fatigue, and low blood sugar (hypoglycemia), which can lead to dizziness, sweating, and in severe cases, unconsciousness. Treatment depends on the cause and may include lifestyle changes such as diet and exercise or medical intervention. It is recommended to seek medical attention if abnormally high insulin levels are suspected, especially if there are accompanying symptoms.
