Reactive hypoglycemia is characterized by the following features:
-More common in overweight and obese people who have insulin resistance, i. e., their organs don't respond well to insulin (normally, insulin causes the sugar in the blood to be up taken and stored in the liver and glycogen)
-May be a frequent precursor to type 2 diabetes
-Possible higher risk in patients with a family history of type 2 diabetes or insulin-resistance syndrome.
Obesity, the most common cause of insulin resistance, is associated with a decreased number of insulin receptors, the molecules found on the surface of the cells to which insulin attaches to exert its effects.
Leptin and ghrelin are 2 hormones that have play an important role in maintaining energy balance. Leptin is an appetite suppressor, thereby inducing weight loss, while ghrelin is a fast-acting hormone, seemingly playing a role in meal initiation. Obese subjects tend to be leptin resistant.
Hypoglycemia may still occur in some individuals with insulin resistance syndrome; such individuals have in their blood auto antibodies (antibodies produced by the immune system against the body itself) that mimic the effect of insulin. In some patients with insulin-binding antibodies, hypoglycemia may occur when insulin dissociates from the antibodies several hours after a meal.
You are advised to do blood tests to rule out a pre diabetes stage: fasting blood sugar, insulin level, and HbA1C (تخزين السكر). You should also reduce your weight.
