What is insulin?
Insulin is natural produced hormone in our bodies by the pancreas. It controls the glucose levels in our blood, regulated fats, proteins, carbohydrates and our metabolism. It stores glucose in our muscles, fat and liver.
Without insulin, our bodies could not properly store glucose then it can begin to break down fat and produce keto acids. In dangerously high levels, this can lead to what is called ketoacidosis and become fatal.
When we consume food, our bodies glucose levels rise and our pancreas begins to secrete insulin in order for glucose to be stored later for energy. For those with type 1 or type 2 diabetes who do not have proper pancreatic function, there bodies do not produce enough insulin or none at all which can lead to drastic fluctuations in blood sugar levels.
For those with diabetes, insulin is administered subcutaneously (underneath the skin) to help control blood glucose levels more efficiently.
There are several types of insulin that have different absorption rates and last for varying periods of time.
What is Novolin 30/70 Insulin
Novolin 30/70 is a premixed insulin which contains both a fast-acting insulin (insulin regular) and an intermediate-acting insulin (insulin NPH). Patients who take this insulin have their blood sugar levels managed and have found this ratio of both insulin types works best for them.
Novolin 30/70 typically begins to work between 30-60 minutes of injection, has a maximum effect between 2-8 hours and stops working up until 18-24 hours.

Blood Glucose Monitoring
It is important for patients using insulin to check their blood glucose levels regularly as recommended by their doctor. Blood glucose levels should also be tested in cases where there is a change in dose schedule due to a time zone difference, a missed meal or being under stress. If you are experiencing high or low blood sugar levels consistently then you should contact your doctor.
Changes at injection site
If you are injecting consistently at the same site you may shrink or thicken fatty tissue. To avoid this from happening, rotate injection sites regularly. Notify your doctor if you notice any skin pitting or thickening at injection sites.
Change in insulin requirements
Insulin requirements may require modification based on blood glucose levels. These may also include:
- certain medical conditions
- certain medications that can affect glucose levels in the blood
- travelling over different time zones
Speak with your doctor about your current health and any changes that may affect blood glucose levels.
It is important to carry identification that lets other know you have diabetes and are taking insulin. This may include a card in your wallet, bracelet or necklace.
Low blood sugar may lead to a decrease in mental alertness or physical abilities. It is important to avoid operating heavy machinery, hazardous tasks or drive if you are experiencing low blood sugar.
Educate Family & Friends
Educate your family and friends about they should do if you experience hypoglycemia and symptoms. Instruct them on how to administer a glucagon emergency kit if you experience low blood glucose levels and lose consciousness.
This may occur if you use too much insulin, miss a meal or exercise too much. Symptoms of hypoglycemia may include cold sweats, nervousness, shakiness, fast heartbeat, hunger, confusion, weakness, numbness or tingling in lips, tongue or fingers. Hypoglycemia may be treated by consuming foods that contain sugar. It is recommended to carry a glucose tablet, candy or sugary drink (non-diet) in case you experience symptoms of hypoglycemia.
Signs of Severe Hypoglycemia may include disorientation, loss of consciousness and seizures. For those who are unable to consume sugar by mouth during severe hypoglycemia may require a family or friend to inject them using an emergency glucagon kit.
Insulin can also cause low levels of potassium. This may happen if you are experiencing vomiting or diarrhea due to illness or from certain medications that may cause low potassium. Symptoms of low potassium may include, leg cramps, slowed heartbeat, constipation or tiredness. If you experience any of these symptoms let your doctor know as low potassium levels can become be fatal.
Pregnancy or Breast feeding
During pregnancy, it is important to properly managed blood glucose levels. During the first trimester insulin levels usually decrease until the second and third when it is increased. Adjustments to insulin levels and diet may be required during breast feeding.
