When someone who has too much sugar in their blood (as in diabetes mellitis), why isn't it excreted?
605060
It is excreted. The problem is that in a healthy body a significant amount of glucose id broken down by insulin. When a person has diabetes, no insulin (or an disfunctional type of insulin) is produced, and the glucose is not being broken down.

I believe you mean diabetes. This is a very serious health condition where the blood sugars are either too high or low.  Diabetes can be genetic, brought on by poor diet and inactive lifestyle or pregnancy-when the hormones become inbalanced and they inhibit the production of insulin in the pancreas.  Diabetes, if left untreated, can cause a myriad of other serious health issues-high blood pressure, high cholesterol, circulatory problems, heart disease, blood clotting, vision problems, migraines, seizures...the list goes on.  The good news is that if you detect it early and treat it seriously-by following the doctor's orders, strict diet and regular excercise, you can live a very long and healthy life.  My father has controlled his diabetes for years, without medication.  He follows a good diet-he allows himself to misbehave once a week, and plenty of excercise.  Some individuals, because of genetic, or a refusal to take ownership of their health, must also rely on medication-which ranges from glucose medications to insulin injections.  I wish you well and hope that you make wise choices.

Diabetes is not a contraindication to donate blood.  It will not increase the recipient's sugar level for example...\n\nNon diabetic people are reccomended not to go fasting to blood bank, and this is more important to you.  After donation you need to rest for an hour more or less, maybe they will offer something to eat, if it is glucose-free, you can go ahead.\n\nIf you get dizziness or thirst after the donation, maybe you are not having a glucose trouble, but an hypovolemia (reduced blood level), easily solvable by resting and drinking glucose-free liquids.

Diabetes is not caused by high sugar.  A person is diagnosed diabetic when you have abnormally high levels in your blood because your body can't metabolize the sugar (glucose)you do have effectively.  When you eat your body breaks down the food, and glucose is absorbed into your cells by something called insulin.  If your body is not producing enough insulin or if the insulin you have is ineffective the glucose stays in your blood stream and your cells starve.  To compensate your body breaksdown fat.  There are two types of diabetics.  Type 1 where the pancreas is not making any insulin.  Most children and young adults get this type. It said to be cause by a virus that kill insulin producing cells in the pancreas called the islet cells.  These patients must take insulin shots because if they take it in a pill the stomach would absorb the insulin and it wouldn't work.  Type 2 is where you have insulin in your body but you are either not making enough or your body isn't using it effectively.  These people can take oral diabetic medication because it is not insulin.  It helps the pancreas to produce more insulin or help the insulin get the glucose in the cell.  Diet and exercise help because your not adding glucose that your body doesn't need and helps you burn off excess and sometimes will force the the glucose into the cell.  Complications from diabetes include blindness, kidney disease, slow healing wounds and loss of feeling to extremities (also called neuropathy).  Symptoms include increased thirst, increased hunger (remember your cells are starving) and increased urination. You can also lose weight because the body is breaking down fat for energy. This mostly happens in Type 1.   I hope this helps.  Remember you can't cause diabetes by eating too much candy but if you are diabetic you can be adding to the problem if you do.  Only a blood test and your doctor can diagnosis diabetes.

Diabetes is a disease in which the body does not produce or properly use insulin. Insulin is a hormone that is needed to convert sugar, starches and other food into energy needed for daily life. The cause of diabetes continues to be a mystery, although both genetics and environmental factors such as obesity and lack of exercise appear to play roles.\n\nThere are 20.8 million people in the United States, or 7% of the population, who have diabetes. While an estimated 14.6 million have been diagnosed with diabetes, unfortunately, 6.2 million people (or nearly one-third) are unaware that they have the disease.\n\nIn order to determine whether or not a patient has pre-diabetes or diabetes, health care providers conduct a Fasting Plasma Glucose Test (FPG) or an Oral Glucose Tolerance Test (OGTT). Either test can be used to diagnose pre-diabetes or diabetes. The American Diabetes Association recommends the FPG because it is easier, faster, and less expensive to perform.\n\nWith the FPG test, a fasting blood glucose level between 100 and 125 mg/dl signals pre-diabetes. A person with a fasting blood glucose level of 126 mg/dl or higher has diabetes.\n\nIn the OGTT test, a person's blood glucose level is measured after a fast and two hours after drinking a glucose-rich beverage. If the two-hour blood glucose level is between 140 and 199 mg/dl, the person tested has pre-diabetes. If the two-hour blood glucose level is at 200 mg/dl or higher, the person tested has diabetes.\nMajor Types of Diabetes\n\n\nThe Complete Guide to Diabetes, 4th EditionFurther Reading . . .\nThe Complete Guide to Diabetes has been completely revised to bring you all the information you need to live an active, healthy life with diabetes. Now in its fourth edition, this guide gives you information on the best self-care techniques and the latest medical advances. If you have diabetes, this guide will answer all your questions.\nFor more books on healthy living, click here.\n\nType 1 diabetes\nResults from the body's failure to produce insulin, the hormone that "unlocks" the cells of the body, allowing glucose to enter and fuel them. It is estimated that 5-10% of Americans who are diagnosed with diabetes have type 1 diabetes.\n\nType 2 diabetes\nResults from insulin resistance (a condition in which the body fails to properly use insulin), combined with relative insulin deficiency. Most Americans who are diagnosed with diabetes have type 2 diabetes.\n\nGestational diabetes\nGestational diabetes affects about 4% of all pregnant women - about 135,000 cases in the United States each year.\n\nPre-diabetes\nPre-diabetes is a condition that occurs when a person's blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes. There are 41 million Americans who have pre-diabetes, in addition to the 20.8 million with diabetes.\nAdditional Information\n\n\nDiabetes Learning Center for the Recently Diagnosed\nYou've just been diagnosed with diabetes.

Liv, in diabetes mellitus the beta cells of the pancreas don't 1) produce enough insulin, 2) produce any insulin or 3) produce a usable insulin.  Insulin regulates the levels of glucose in the blood.  If there is no insulin production, as in Type I, or little insulin production or insulin that cannot be used (such as with central obesity--fat is insulin resistant), as in Type II, then there is nothing to regulate and lower glucose levels in the blood.  A higher than normal level of glucose is called hyperglycemia.  That is why hyperglycemia is a symptom of IDDM Insulin dependent diabetes mellitus) and NIDDM (Non-insulin dependent diabetes mellitus).  I tried to keep it simple.

Limit your carb intake. The body turns all carbs into sugar. With simple carbs; sugar, honey, syrup, etc. the body converts these quickly causing your blood sugar to spike so avoid these. Complex carbs like rice, oatmeal, beans, etc. take longer to convert so your blood sugar doesn't spike, but it will still go up. You also have to be careful not to eat too much protein. Protein won't effect your blood sugar, but will effect your kidneys which are already working overtime trying to get rid of the excess sugar. Make an appointment and talk with a dietitian. In the meantime practice portion control. That's where most of us get in trouble. 1/2 Cup is a serving of starch like corn, beans, pasta, potatoes. 1 Cup is a serving of raw veggies and 1/2 Cup cooked veggies = a serving. 1 oz. of meat = 1 serving of meat. Watch your diet and talk with a dietitian and you should be able to control your diabetes without having to go on meds. OH and always carry some hard candy with you in case your blood sugar gets too low. Good luck with this.

The presence of sugar in your urine is a classic sign of diabetes.  But since you asked this question in the diabetes section, you probably already know this, neh?\n\nYou see, normally when you eat something it's broken down into a bunch of sugars and other stuff in your blood.  Your pancreas then spits out insulin which lets your cells absorb the sugar.  If for some reason you don't have enough insulin in your blood, the sugars just pass through your system and end up in your urine.\n\nIf this is proven to be the case with you, you'd have type 2 diabetes.  Most diabetes cases are actually 'type 2'.  Catching it early can help A LOT.  If it's mild enough, you may only have to change your diet slightly.  But even if it's severe, it's MUCH better to have it treated than to progress on to the real nasty side effects at the end.\n\nOr it may be a false positive on a test.  I'll keep my fingers crossed for you!  (  :

if the glucose concentration (and osmotic level) is too high, the microorganism that does the respiration cannot exist or metabolize. like a concentrated syrup or honey. it is simply too concentrated to allow microbial growth, get it?

Sugar is used by the body during many of life's processes. It is just another chemical that exists in food and is used by the body. A diabetic is not making enough of the chemical that the body uses to control sugar use, called insulin. The level of sugar goes out of control and can cause diseases shock, coma and death. The diabetic has to control the level of sugar be regular eating habits and blood monitoring. When needed they can take insulin to help control blood sugar.

A sudden increase in blood glucose concentration leads to the release of a specific hormone in the human body: insulin. Insulin is released to reduce the concentration of sugar in the blood. In order to do this, it promotes muscular uptake of sugar, by promoting muscular activity.  \n\nThis is why people with diabetes do not show this phenomenon. Type I diabetes patients do not secrete insulin (hence the need for insulin shots). Type II diabetes patients have modified receptors that prevent insulin from being recognized by the muscle cell.

Insufficient insulin levels lead to hyperglycemia, which is an abnormally high blood glucose (sugar) level. The overall medical condition is called diabetes.\n\nType I diabetes occurs when your immune system destroys the Islets of Langerhans in the pancreas, which produce insulin.\n\nType II diabetes occurs when the pancreas produces the correct amount of insulin, but either the insulin is defective or the cells that require insulin for glucose uptake become resistant to insulin. \n\nTherefore, if your pancreas isn't making ENOUGH insulin, it is probably due to Type I diabetes.

Glycosuria is common in both, but depends on the level. At a plasma glucose up to about 240 mg/dL (give or take a few), the Kidney reclaims all the glucose, so above that, the glucose spills into the urine and drags water with it. In IDDM, glucose easily goes above 240, but in NIDDM, it is possible that the glucose is only slightly elevated, such that glycosuria (and even polyuria) may not happen. This is why NIDDM has more complications at diagnosis - the glucose has been elevated long enough to cause DAMAGE, but not high enough to cause SYMPTOMS. In IDDM, the sugar rises high enough to cause symptoms, and quick enough to diagnose and treat BEFORE complications.\n\nMake sense?

Yes it can lead into diabetes if you are not careful, if your blood suger gets low use glucose tabs, peanut butter, eggs, or juice to level it out, but never sugary candy, watch your candy intake, I too have this problem

check the glucose content in honey. My father had diabetes and he insisted that he could eat all the honey that he wasted but when I had gestational diabetes I was told that honey is only slightly healthier than sugar and should also be used with caution.\nTalk to your doctor.

I'm a Type 2 diabetic myself, and I can speak from experience here...if I eat something heavy in sugar or carbs, especially without anything else in my system, my body "crashes" after the initial sugar rush wears off.  One of the big problems with Type 2 is the wild variations in blood sugar count at any given time...it's like your bidy doesn't react in any stable way to big swings in blood sugar count.

Correction- insulin does not remove glucose from the urine. It removes it from the bloodstream, and redirects it to glycogen, to be stored in the tissues.  It can also be stored as fat. IF her blood sugar is too high, she is eating the wrong things. She needs to watch her diet, and have a low carb profile. IF she eats low-carb, then her blood sugar will not spike like that, and the insulin will have nothing to act upon in a negative fashion.\n\nHer blood sugar is high to begin with because of a lack of natural insulin in her body, which then needs to be supplemented by injected insulin. The job of insulin is to remove excess glucose from the bloodstream. Excess sugar in the blood is like having a thick syrup circulating around. This is bad for the body, and causes the blood pressure to go up, which can cause strokes and heart attacks. When insulin acts in a normal body, it brings the sugar level back down to normal after a meal.\n\nShe does not need to eat more. This will really make her fat.  She needs to eat low carb more frequently.  This will keep her blood sugar more normal. \n\nThe higher the blood sugar, the  more insulin is needed, and the more the glucose will be stored as fat or glycogen.\n\nShe should never take insulin if her blood sugar level is normal or low, because insulin will still act in the same way, and drop her level to below normal. If it does go too low, she could go into a diabetic coma.\n\nIt all has to do with keeping the sugar level in balance - both with diet and with the insulin. \n\nDoes that make sense yet?
