Fasting InsulinUpdated 3 months ago

What is Insulin?

Insulin is a hormone produced by the pancreas that helps regulate blood sugar levels. After eating, insulin is released to promote the usage and storage of glucose in the body.

Why is Fasting Insulin Important?

Fasting insulin levels can help detect early signs of diabetes and metabolic syndrome. About 1 in 10 Americans have diabetes, and many are unaware of it. Type 1 diabetes occurs due to insufficient insulin production, while type 2 diabetes is caused by insulin resistance. Gestational diabetes affects pregnant women and can impact both mother and baby. Insulin is important not only for those with diabetes but also for monitoring overall metabolic health.

Understanding Insulin Levels

Insulin follows a daily rhythm, so maintaining a consistent routine can help keep levels stable. It's recommended to test insulin levels in a fasted state (no food for 8 hours). Here are fasting insulin ranges:

• Low: <1.9 uIU/mL
• Optimal: 1.9-8 uIU/mL
• High: 8-23 uIU/mL
• Very High: >23 uIU/mL

Elevated fasting insulin can signal insulin resistance, where the body needs more insulin to manage glucose.

Symptoms of Insulin Resistance

Common symptoms include:

• Increased thirst, hunger, and urination
• Blurred vision
• Slow-healing sores
• Skin changes (e.g., darkened areas or skin tags)

Maintaining Optimal Insulin Levels

• Diet: Focus on low glycemic index foods like beans, vegetables, and berries.
• Lifestyle: Regular exercise and weight management can improve insulin sensitivity.
• Consult a Doctor: Hormonal disorders and certain medications can also affect insulin levels, so professional guidance is important.
