Uncommon: In someone with a normal GI tract, hypoglycemia after a meal is very uncommon. To be fair, some people feel yucky 2 hr after eating a sugar-rich meal. But it is rarely a low blood sugar. Most people will not feel symptoms unless the blood glu is <60. I people who have had gastric bypass or other GI surgeries, post meal hypoglycemia can occur. One cause is nesidioblastosis. ...Read more
Overdiagnosed: It does exist, but is very uncommon and has been grossly overdiagnosed and hyped. Many people get symptoms 3-4 hr after a sugary meal even tho glu is normal, and people have "low" glu with no symptoms at all. If you have post-meal symptoms, best treatment is smaller/frequent meals/complex carbs/protein etc (after stomach surgery, eg gastic bypass, reactive hypo can occur). ...Read more
Yes: This is a tough question to answer as it depends what you mean by real. There are several things which cause reactive hypoglycemia but loosely this term refers to a style of digestion in which blood sugar suddenly drops to low enough levels to cause symptoms up to 4 hours after a meal. It is caused when the body is still releasing Insulin after a meal is digested resulting in a sugar drop. ...Read more

Yes...: Reactive hypoglycemia is defined as a drop in blood sugar after of eating, usually a meal high in sugar or carbohydrates. There is some controversy over the diagnosis and it is not a "formally" recognized D.C., however, clinically it is something that in my opinion & the endocrinologist I know clearly exists & guidelines for its tx exist. It often occurs in people w a FH of DM or pre-DM. ...Read more
No: In my 35 years of practice, I have never seen a case of reactive hypoglycemia. The disorder doesn't exist, if you're overweight the symptoms are a natural response to your glucose level returning to normal. A glucose tolerance test (if you've had one) is not and never will be a valid diagnostic test for hypoglycemia. Don't waste your money o GTT or any fad diets of treatments. Lose wt if heavy. ...Read more
My g t t shows a drop from 7.8 down to 4. 0mmol in the first hour. The lowest value was 3.6mmol. Does this suggest reactive hypoglycemia?
Fainting?: Not so much. Feeling like fainting is much more common. Happens. The physiology of it is in people who are becoming diabetic, they are not sensitive to insulin and the insulin regulation is off. The first thing is that with less sensitivity to it, the amount of insulin secreted goes sky high. Then, if there isn't enough sugar... reactive hypOglycemia and feeling empty. ...Read more
N+you don't have it: Biotin isn't useful for anything except increasing "health food" store revenue. In addition, in my 35 years of practice, I have never seen a case of reactive hypoglycemia. The disorder doesn't exist, if you're overweight the symptom are a natural response to you sugar returning to normal. A glucose tolerance test (if you've had one) is not and never will be a valid diagnostic test for hypoglycem. ...Read more
One is med induced: Reactive hypoglycemia means blood sugars drop after eating a high carb meal due to an exaggerated response by the pancreas. People with diabetes get hypoglycemic when their carb intake does not match their med intake or when they expend more calories than they usually do and take the same amount if Insulin or other meds. ...Read more
Can reactive hypoglycemia be cured forever so in the future I won't have to worry about what I'm eating or drinking?
Hypoglycemia: Eating small regular frequent meals is the best defense against reactive hypoglycemia. ...Read more
Not so much: It is a response to hyperinsulinemia, which is the first step towards adult onset or type 2 diabetes. When one becomes obese, the body begins to ignore the message of insulin. The response in the pancreas is to secrete more insulin. When challenged with a meal the Insulin response is too much and when the meal is digested, there is still Insulin available but no food and the blood sugar drops. ...Read more
