Glucose intolerance measures the body’s response to sugar. This test is used for patients suffering from type 2 diabetes mellitus. This is also used to diagnose gestational diabetes (a type of diabetes that occurs during pregnancy).
This test identifies the abnormality after having a meal. After doing the test, the patient may feel dizziness, light-headedness, and may observe bleeding.
If you face Hyperglycemic symptoms after a meal, or if you observe that your body is sensitive to glucose, you may consider a glucose intolerance test from a lab in Humble.
Before the procedure
The patient is advised not to consume any food or drink, and fast overnight, to get a more reliable result. The doctor advises the patient to not consume more than 150 grams of carbohydrate for three days before the test.
If the patient is taking any type of medication, he or she must discuss it with the doctor.
During the procedure
The testing is usually done in the morning, and the patient needs to stay in the clinic for at least 3 hours before the test.
The doctor will start drawing blood from a vein (often from the arm). The technician ties a band around the upper arm for easier access to the vein. The technician will wipe the skin with a sterile wipe.
A small needle is inserted into the vein. Once the test is done the patient is given a glucose solution and the blood is taken several times from the patient.
After the procedure
After the test is done, the patient experiences mild pain from where the blood is drawn, and the patient can resume normal activities and be allowed to consume food.
Blood glucose is considered normal if the blood glucose level is less than 140 mg/dl. If the test result is between 140 and 190 mg/dl, this indicates a pre-diabetic condition, and above that, the patient is considered suffering from diabetes.
If the test is positive, the patient needs to follow a low-carb diet.
- The patient is advised not to eat fruits that are rich in glucose, such as grapes.
- The patient needs to eat seafood, which provides a good source of proteins, healthy fats, vitamins, and antioxidants. This regulates blood sugar levels.
- Eating nuts and nut butter (peanut butter) plays a crucial role in a low carb diet which maintains blood sugar levels.
After a meal, if you feel heavy after a while or you feel your lips are drying up and feel sticky, this might be an indicator for increased blood sugar. In such cases, you need to consider a doctor and get immediate help.
