Diabetes-Related High and Low Blood Sugar Levels - Topic Overview
When you have diabetes, you may have high blood sugar levels (hyperglycemia) or low blood sugar levels (hypoglycemia) from time to time. A cold, the flu, or other sudden illness can cause high blood sugar levels. You will learn to recognize the symptoms and distinguish between high and low blood sugar levels. Insulin and some types of diabetes medicines can cause low blood sugar levels.
Learn how to recognize and manage high and low blood sugar levels to help you avoid levels that can lead to medical emergencies, such as diabetic ketoacidosis or dehydration from high blood sugar levels or loss of consciousness from severe low blood sugar levels. Most high or low blood sugar problems can be managed at home by following your doctor's instructions.
Following your doctor's instructions on the use of insulin or diabetes medicines, diet, and exercise will help you avoid blood sugar problems. Home blood sugar testing will help you determine whether your blood sugar is within your target range. If you have had very low blood sugar, you may be tempted to let your sugar level run high so that you do not have another low blood sugar problem. But it is most important that you keep your blood sugar in your target range. You can do this by following your treatment plan and checking your blood sugar regularly.
Children with diabetes need their parents' help to keep their blood sugar levels in a target range and to exercise safely. It is important for children to learn the symptoms of both high and low blood sugar so they can tell others when they need help. There are many support groups and diabetes education centers to help parents and children understand about blood sugar, exercise, diet, and medicines.
Teens especially may have a hard time keeping their blood sugar levels in control because their bodies are growing and developing. Also, they want to be with their friends and eat foods that may affect their blood sugar. Having diabetes during the teenage years is not easy. But your teen is at an excellent age to understand the disease and its treatment and to take over some of the responsibilities of his or her care.
If your blood sugar level reads too high or too low but you are feeling well, you may want to recheck your sugar level or recalibrate your blood glucose meter. The problem may be with either your blood sample or the machine.
High blood sugar (hyperglycemia)
High blood sugar occurs when the sugar (glucose) level in your blood rises above normal. Eating too many calories, missing medicines (insulin or pills), or having an infection or illness, injury, surgery, or emotional stress can cause your blood sugar to rise.

Indication
Uroxatral® (alfuzosin HCl 10 mg extended-release tablets) is an alpha1-blocker for the treatment of the signs and symptoms of BPH.
Important Safety Information
Do not take UROXATRAL if you have liver problems or if you are taking antifungal drugs like ketoconazole or itraconazole, or HIV drugs like ritonavir.
UROXATRAL can cause a sudden drop in blood pressure, especially when starting treatment. This may lead to fainting, dizziness, and lightheadedness. Do not drive, operate machinery, or do any dangerous activity until you know how UROXATRAL will affect you. This is especially important if you already have a problem with low blood pressure or take medicines to treat high blood pressure. There may be an increased risk of low blood pressure and fainting when taking UROXATRAL in combination with blood pressure medication or nitrates, or erectile dysfunction medication.
If considering cataract surgery (clouding of the eyes), tell your eye surgeon that you are currently taking UROXATRAL or have previously been treated with an alpha-blocker.
Before taking UROXATRAL, tell your doctor if you have kidney problems.
Also, tell your doctor if you or any family member(s) have or take medications for a rare heart condition known as congenital prolongation of the QT interval.
BPH and prostate cancer can cause the same symptoms. However, UROXATRAL is not a treatment for prostate cancer.
The most common side effects with UROXATRAL are dizziness, upper respiratory tract infection, headache, and tiredness.
