What Is Postprandial Syndrome
Postprandial syndr.: It describe a group of patients with symptoms suggestive of increased sympathetic activity (anxiety, weakness, tremor, perspiration, or palpitations) occurring after meals. The cause might be having too much Insulin release in reaction to a particular food eaten. Treatment is to find the direct cause or the direct foods and avoid it. ...Read more
I have symptoms of "idiopathic postprandial syndrome". Is this a condition recognized by most health professionals? Could i talk to my gp about it?
My fasting glucose is consistently 100-115, and yet post prandial 1 hr is 160, 2 hr is 86. Last vap showed negative for metabolic syndrome. Is this a result of nighttime glycogen dump, and if so, why? And why the normal post prandial?
Pre-diabetes: People with pre-diabetes/early diabetes can produce higher level of Insulin to keep bs somewhat adequate, sometimes they overshoot and can cause subsequent low blood sugar after a meal, especially if it's a high carbohydrate meals. As of now, you have impaired fasting sugar which is a form of pre-diabetes. You might need a hba1c test (blood test) to see your overall level of glucose control. ...Read moreSee 2 more doctor answers
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
Insulin or glucose?: Normal is 65-105 when drawn out of a vein while fasting. Various authorities have different "normal" levels. There are, however, no exact cut-offs, it's all a continuium. Finger sticks are not accurate enough. Two hour post meal should be less than 130-140, and any glucose >200 at any time suggests diabetes. An a1c >6% is also suggestive and needs further evaluation. See diabetes.Org for info. ...Read more
Please explain what do we mean by basic secretion of insulin and by the postprandial peak on the secretion of insulin?
Basal, not "basic": Hi. The body needs insulin when you're fasting; this is referred to as "basal insulin"; it provides a background anti-catabolic effect. The meal burst of insulin secretion is to handle the sudden influx of dietary nutrients (NOT just carbohydrates) into the system, and to promote their uptake and storage in several tissues (liver, muscle, and adipose). Different functions of insulin. ...Read more
I was wondering what does it mean by basic secretion of insulin and by the postprandial peak on the secretion of insulin?
Insulin: Hi. The body needs some Insulin even when you're not eating in order to prevent breakdown of muscle and too much release of fat from fat cells and glucose from the liver; this is called "basal" Insulin (not "basic"). When you eat, you need a burst of Insulin to manage the caloric burst of the meal and to clear glucose (and indirectly, fats) from the blood (prandial insulin) and store them. ...Read more
