Usually before injecting insulin , the first thing to do is to decide how much insulin to start. Let’s talk about this knowledge with you.
Type 1 diabetes patients commonly use the following method. Generally speaking, when diabetic patients first start taking insulin, they usually take three to four times a day. Among them, the injection dose before breakfast is the largest, followed by before dinner, and before lunch with a smaller dose. If an additional injection is needed before going to bed, the dose at this time is the smallest; Type 2 diabetes patients can also start with one or two injections of premixed insulin preparations per day. If the patient mainly suffers from poor fasting blood sugar of and , this injection preparation can be injected before dinner or before going to bed; if the patient mainly suffers from poor blood sugar two hours after breakfast, insulin injection can be performed on an empty stomach in the morning.
In reality, there are many methods that can be used as a reference value for the initial dose.
1. You can choose according to the amount of urine sugar : Generally speaking, when the urine sugar is several plus signs, you should take an appropriate amount of insulin before the last meal according to 2-3 units of each plus sign. For example, if the urine sugar level before lunch is three plus signs, you can take 6-10 units of insulin at breakfast at the beginning. If your fasting urine glucose is three plus signs, you should take 6-10 units of insulin before dinner the day before or before going to bed.
② Inject insulin according to the level of blood sugar: Calculate the dosage of insulin according to the formula of (blood sugar - 100) x kilogram of body weight x 6 + 2 000.
③ Calculated based on each tablet of sulfonylurea hypoglycemic drug combined with 5 units of insulin: if you take two tablets of or hypoglycemic before breakfast, it can be changed to 10 units of insulin;
④ Determine the dosage of insulin based on experience: You can decide to inject 8, 4, 6 units or 10, 6, 8 units of insulin before three meals according to the level of blood sugar as the initial dose of insulin. This is a relatively simple and practical method.
You can choose the dosage of insulin for a few days according to the methods mentioned above, and then further adjust it according to the level of blood sugar control.
