It is our source of energy, the \u201cfuel\u201d used by every cell in our body, and is essential for life. However, both too much and too little sugar lead to serious problems. Glucose levels are regulated by a hormone produced by the pancreas, called insulin, which allows every cell in our body to take up glucose and use it. Insulin acts like a traffic controller: it determines whether glucose passes from the blood into cells or is stored as a reserve in the form of glycogen and\/or triglycerides. Sugar, which our body needs so much, can also become a toxic substance that damages our organs. Your glucose level (also called your blood sugar level or glycaemia) on an empty stomach should remain within the range of 70-99 mg\/dL.<\/p>\n<p>In pancreatic diseases involving abnormal insulin secretion and consequently disrupted glucose metabolism, symptoms may go unrecognised for a long time.<\/p>\n<p>Symptoms of raised blood glucose (known as hyperglycaemia), including diabetes:<br \/>\n\u2022 increased thirst (unrelated to increased exertion, excessive sweating or fever)<br \/>\n\u2022 passing larger amounts of urine than before<br \/>\n\u2022 feeling weak\/fatigued<br \/>\n\u2022 reduced visual acuity<br \/>\n\u2022 wounds that are slow to heal.<\/p>\n<div class=\"badamy-sie-box\" style=\"width: 100%; padding: 20px; color: #ccc;\"><a href=\"\/\/badamysie.pl\"><img decoding=\"async\" src=\"http:\/\/www.badania-medyczne.pl\/wp-content\/uploads\/2015\/11\/kup-badanie-na-badamysie.jpg\" rel='prettyPhoto' alt=\"\" \/><\/a><\/div>\n<table>\n<tbody>\n<tr>\n<td style=\"text-align: center;\"><strong><span style=\"color: #000080;\">You can purchase individual blood tests and blood test packages designed by Polish specialists on<\/span> <a href=\"https:\/\/badamysie.pl\">BadamySie.pl <\/a><span style=\"color: #000080;\">and have them carried out at the laboratory you select during purchase, using the confirmation sent to you by email just moments after the transaction.<\/span><\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Symptoms of blood sugar that is too low (known as hypoglycaemia)<br \/>\n\u2022 sweating<br \/>\n\u2022 feeling hungry<br \/>\n\u2022 muscle tremors<br \/>\n\u2022 anxiety<br \/>\n\u2022 disorientation<br \/>\n\u2022 blurred vision<\/p>\n<p>In both cases, fainting or sudden weight loss (without a change in diet) may also occur, which is associated with abnormal glucose metabolism.<\/p>\n<p>Blood glucose levels can also be measured easily using laboratory tests on capillary blood (a drop of blood from a fingertip prick) or the more accurate laboratory test on venous blood.<\/p>\n<p>Remember to attend this test on an empty stomach, meaning about 8 hours without food or drink (except still, unsweetened mineral water).<\/p>\n<p>Fasting blood glucose values:<\/p>\n<p>-normal value 70-99 mg\/dL (mg%)<\/p>\n<p>-raised level 100-125 mg\/dL (mg%), known as prediabetes<\/p>\n<p>-an excessively high blood glucose level above 125 mg\/dL (mg%) in two measurements taken on different days is diagnosed as diabetes.<\/p>\n<table>\n<tbody>\n<tr>\n<td style=\"text-align: center;\"><span style=\"color: #000080;\">Choose the package, test or medical consultation you are interested in from the<\/span> <strong><a href=\"https:\/\/badamysie.pl\" target=\"_blank\" rel=\"noopener noreferrer\">shop<\/a> and <a href=\"https:\/\/badamysie.pl\" target=\"_blank\" rel=\"noopener noreferrer\">purchase online<\/a><\/strong>. <strong><span style=\"color: #000080;\">When you use<\/span> <a href=\"https:\/\/badamysie.pl\">BadamySie.pl<\/a> <span style=\"text-decoration: underline; color: #000080;\">you do not pay an additional fee for blood collection at the laboratory <\/span><\/strong><span style=\"color: #000080;\">(if you do not use the BadamySie.pl portal, a fee is always added when you purchase tests in the usual way at the clinic)<strong>.<\/strong><\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The most common cause of raised blood glucose is diabetes.

This test checks how your body copes with a sudden, fairly large dose of sugar. It is also routinely performed in pregnant women between 24 and 28 weeks of pregnancy to check the risk of developing gestational diabetes. The result report is issued in Polish.<\/p>\n<p>The glucose tolerance test starts with a venous blood sample taken on an empty stomach. You then need to drink the amount of glucose prescribed by your doctor, which you should purchase from a pharmacy beforehand. Depending on the doctor&#8217;s instructions, blood is collected after one hour and\/or after two hours. During an OGTT, blood is therefore collected twice: on an empty stomach and after 2 hours, or three times: on an empty stomach, after one hour and after two hours. It is important not to leave or go for a walk away from the testing site during the glucose tolerance test, because any physical exertion can distort the results. The glucose solution should also be drunk slowly, in small sips, over 5 minutes (rather than all at once), as drinking it too quickly may cause fainting. You must not consume any food or fluids between blood collections either.<\/p>\n<table>\n<tbody>\n<tr>\n<td style=\"text-align: center;\"><strong><span style=\"color: #000080;\">Check whether our laboratories are already in your city!
