When Should I Take Insulin

Glucose Insulin and Diabetes

You and your doctor should discuss when and how you will take your insulin. Each persons treatment is different. Some people who use regular insulin take it 30 to 60 minutes before a meal. Some people who use rapid-acting insulin take it just before they eat.

Types of insulin:

  • Rapid-acting insulin starts working in about 15 minutes. It lasts for 3 to 5 hours.
  • Short-acting insulin starts working in 30 to 60 minutes and lasts 5 to 8 hours.
  • Intermediate-acting insulin starts working in 1 to 3 hours and lasts 12 to 16 hours.
  • Long-acting insulin starts working in about 1 hour and lasts 20 to 26 hours.
  • Premixed insulin is a combination of 2 types of insulin .

How Do You Take Insulin Without A Syringe

There are several options:

  • Insulin pens look like large writing pens and can help prevent under- and overdosing. They also dont require refrigeration, are conveniently prefilled, and are more durable than syringes.

  • Insulin pumps are attached to a thin tube thats implanted under your skin. Pumps are computerized or motorized, and some models also act as glucose monitors. They deliver insulin before each meal along with small amounts through the course of the day. In the US, about 60% of people with diabetes use some form of .

  • Jet injection devices are a good option if you hate needles. A jet injector holds several doses of insulin. After placing it against your skin, you press a button, and the insulin is pushed through.

  • Inhaled insulin comes in a pre-measured inhaler and was first approved in 2014. Its short-acting and usually not covered by insurance, which makes it more cost prohibitive than other types of insulin for most people with diabetes.

Unless you have an insulin pump that also works as a glucose monitor, insulin dosing is based on self-monitoring your blood glucose levels. You can check them by doing finger pricks or wearing a device that continuously monitors them for you.

Insulin And Blood Glucose Levels

Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy.

If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

The liver can store up to around 5% of its mass as glycogen.

Some cells in the body can take glucose from the blood without insulin, but most cells do require insulin to be present.

The Link Between The Gut And The Pancreas

Insulin is produced in higher amounts when sugar passes through the gut compared to when glucose is injected into the veins . This is because when sugar enters the gut, messages are sent from the gut to the pancreas to produce more insulin. These messages are chemicals called peptides. The best known gut peptide controlling insulin is called GLP1 . GLP1 speaks to the pancreas after glucose enters the gut, telling it to produce insulin at the right time. It is now known that in type 2 diabetes, GLP1 levels are too low, which is partly why blood sugar levels go too high after a meal . There are now many medicines that increase GLP1 levels to control post-prandial hyperglycaemia which are therefore good treatments for type 2 diabetes.

Exercise & Physical Activity

Illustration of insulin and glucose production in Type 2 diabetes ...

Since Chauveu & Kaufmans remarkable observation in 1887 that When a horse chews on hay the concentration of glucose in the blood draining its masseter muscle substantially decreases74 a large body of evidence supports the role of exercise in improving insulin sensitivity and its beneficial outcomes in insulin resistant states. Epidemiological studies such as the US Physicians Health Study have reported substantial decreases in the relative risk of type 2 diabetes with lifelong regular physical activity.75 Large scale randomised controlled clinical trials such as the Diabetes Prevention Program76 and the Finnish Prevention Study77 demonstrate a 58% reduction in progression of impaired glucose tolerance to type 2 diabetes by intensive lifestyle modification which included a minimum of 2030 minutes of exercise per day. Acute exercise increases GLUT 4 translocation to sarcolemmal membrane, whereas chronic exercise training increases Glut 4 mRNA expression.78 In addition to this insulin-dependent mechanism, enhanced glucose uptake into exercising muscle occurs by multiple insulinin dependent mechanisms.79 Exercise training appears to enhance insulin sensitivity by increased post-receptor insulin signalling 80 increased insulin-mediated glucose transport appears to be related to enhanced signal transduction at the level of IRS proteins and PI 3-kinase.79

The Role Of Glucagon In Blood Glucose Control

The effect of glucagon is to make the liver release the glucose it has stored in its cells into the bloodstream, with the net effect of increasing blood glucose. Glucagon also induces the liver to make glucose out of building blocks obtained from other nutrients found in the body .

Our bodies desire blood glucose to be maintained between 70 mg/dl and 110 mg/dl . Below 70 is termed “hypoglycemia.” Above 110 can be normal if you have eaten within 2 to 3 hours. That is why your doctor wants to measure your blood glucose while you are fasting…it should be between 70 and 110. Even after you have eaten, however, your glucose should be below 180. Above 180 is termed “hyperglycemia” . If your 2 two blood sugar measurements above 200 after drinking a sugar-water drink , then you are diagnosed with diabetes.

Insulin Questions: How do I treat my low blood sugar?

Insulin-like growth factors are so-called because they have significant structural homology with proinsulin but mainly mitogenic effects, significantly regulated by growth hormone.31 IGF-1 and 2 are coded for on the long arm of chromosome 12 and short arm of chromosome 11 respectively.32 They have specific receptors and bind with different affinities to the various IGF binding proteins. Insulin can bind to the receptors for IGF-1 and 2 but with much lower affinity respectively. IGF-1 binds weakly to the insulin receptor, with only 1.25×103 the affinity for the IGF-1 receptor it binds the IGF-2 receptor with 1/4 the affinity for the IGF-2 receptor. IGF-2 does not bind to the insulin receptor it does bind the IGF-1 receptor but with 1/3 the affinity for the IGF-2 receptor.29 Therefore overlap in physiological functions is more limited in vivo.

Why Would Someone Without Diabetes Monitor Blood Sugar

Dana Angelo White, M.S., RD, a cookbook author and owner of Dana White Nutrition, Inc., says she really doesn’t see the point of monitoring blood sugar if you don’t have diabetes. “As a temporary experiment, it may be interesting to monitor the blood sugar fluctuations that occur during meals, sleep and exercise. Seeing how your body responds appropriately may provide some reassurance and, of course, may help you make some changes .”

What Will Insulin Be Like In The Future

Pharmaceutical companies are working on very long-acting versions of insulin that could last for a week. There is also an ultra-fast version of insulin under development that will act in less than 15 minutes.

Another group of researchers is looking at glucose responsive insulin , which would react to the needs of your body in real time. It would have nanosensors bound to the insulin so that when insulin is needed, it releases, and when it isnt, it stops, according to Dr. Hirsch.

When Should Insulin Be Started

Q. Will my patient with type 2 diabetes require insulin?

A. It varies from patient to patient. However, type 2 diabetes is a progressive disease marked by gradual loss of beta cell function and most patients will eventually require insulin therapy.1 This should be viewed as part of the pathophysiology of the disease and not as a failure on the part of the patient or healthcare provider.

Insulin should be discussed early with patients who are beginning to show progression of their diabetes to ease the transition when the time to start insulin therapy arrives. This time should be considered part of a larger conversation between provider and patient, and not seen as a turning point down a path to the many severe complications of diabetes.

Q.Is there a specific hemoglobin A1c at which insulin must be started?

A. No. Insulin, like all treatments for diabetes, should be started and adjusted to achieve a reasonable goal HbA1c for the patient. The American Diabetes Association previously recommended that a patients HbA1c not be allowed to exceed 8%, creating an action point for escalation of therapy.

Insulin therapy will often need to be started if the initial fasting plasma glucose is greater than 250 or the HbA1c is greater than 10%.4_________________________________________________________________________________________________________________________________________________________________________________________________________________

Achieving Normal Blood Glucose Levels

Endocrine and Homeostasis physio

People with type 1 diabetes must take daily insulin to control their blood glucose levels. Insulin is usually given by injection or via an insulin pump.

People with type 2 diabetes can often control their blood sugar levels with a healthy diet, sufficient exercise and/or the use of tablets known as oral hypoglycaemic medicines, such as metformin. Eventually, however, many people with type 2 diabetes will also require insulin injections to keep their blood sugar levels steady.

People with diabetes need to monitor their blood sugar levels regularly. Your general practitioner , endocrinologist and diabetes educator will work with you to set goals for your optimum blood glucose levels before and after meals.

Blood sugar level targets, or goals, are usually set specifically for an individual. Factors that help work out your personalised target blood sugar levels include the type of diabetes you have and whether you are prone to episodes of low blood sugar .

Random Blood Sugar Test

The Random Blood Sugar test is done any time of the day outside the regular testing timetable. Medical professionals recommend using this test to confirm the presence of diabetes during and after the treatment of diabetes. A level of 200 mg/dl or greater indicates diabetes mellitus.

The primary objective of the RBS test is to check random blood sugar levels. The test helps treat the disease via timely monitoring during and after treatment. The random blood sugar level test is recommended if an individual complains of any of the following signs:

What Problems Can Happen With Type 2 Diabetes

Not having the right amount of sugar in the blood can lead to:

  • hyperglycemia.This is when blood sugars are too high. Someone with hyperglycemia may be extra thirsty and pee more than usual. If high blood sugars arent treated, they can get very sick and have health issues later in life, like heart and kidney problems.
  • diabetic ketoacidosis . This serious condition needs treatment right away. When theres not enough insulin in the body to let the glucose into the cells, the body starts to break down fat instead of sugar. Symptoms of DKA can include nausea, vomiting, belly pain, fast breathing, and in severe cases, unconsciousness. DKA happens more often in people with type 1 diabetes, but it can sometimes happen to those with type 2 diabetes.
  • hyperglycemic hyperosmolar state . Like DKA, this is a serious condition that needs treatment right away. People with HHS have severe dehydration and very high blood sugars.
  • hypoglycemia. This is when blood sugars are too low. It can sometimes happen when people with type 2 diabetes are treated with insulin. If a person with diabetes gets more insulin than they need, their blood sugar level can drop too low. Symptoms can include headache, weakness, shakiness, anxiety, and sweating.

What Should I Do If My Blood Sugar Gets Too Low

Exercise and Insulin Stimulated Glucose Uptake by Skeletal Muscle

Low blood sugar is also called hypoglycemia . It means your blood sugar level drops below 70. Having low blood sugar is dangerous and needs to be treated right away. Anyone with diabetes can have low blood sugar. You have a greater chance of having low blood sugar if you take insulin or certain pills for diabetes.

Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry, check your blood sugar. Even if you feel none of these things, but think you may have low blood sugar, check it.

If your meter shows that your blood sugar is lower than 70, do one of the following things right away:

  • chew 4 glucose tablets
  • drink 4 ounces of fruit juice
  • drink 4 ounces of regular soda, not diet soda or
  • chew 4 pieces of hard candy

After taking one of these treatments, wait for 15 minutes, then check your blood sugar again. Repeat these steps until your blood sugar is 70 or above. After your blood sugar gets back up to 70 or more, eat a snack if your next meal is 1 hour or more away.

If you often have low blood sugar, check your blood sugar before driving and treat it if it is low.

Can Lions Mane Cause Hypoglycemia

No, lions mane cant cause hypoglycemia, but it does have hypoglycemic effects. Therefore, if youre taking lions mane and medication that increases your insulin level, you could experience low blood sugar levels. To avoid hypoglycemia, make sure you stick to a diet regimen set by a healthcare professional and check your blood sugar regularly.

How Do Doctors Diagnose Insulin Resistance And Prediabetes

Doctors use blood tests to find out if someone has prediabetes, but they dont usually test for insulin resistance. The most accurate test for insulin resistance is complicated and used mostly for research.

Doctors most often use the fasting plasma glucose test or the A1C test to diagnose prediabetes. Less often, doctors use the oral glucose tolerance test , which is more expensive and not as easy to give.

The A1C test reflects your average blood glucose over the past 3 months. The FPG and OGTT show your blood glucose level at the time of the test. The A1C test is not as sensitive as the other tests. In some people, it may miss prediabetes that the OGTT could catch. The OGTT can identify how your body handles glucose after a mealoften before your fasting blood glucose level becomes abnormal. Often doctors use the OGTT to check for gestational diabetes, a type of diabetes that develops during pregnancy.

People with prediabetes have up to a 50 percent chance of developing diabetes over the next 5 to 10 years. You can take steps to manage your prediabetes and prevent type 2 diabetes.

The following test results show Prediabetes2

  • A1C5.7 to 6.4 percent
  • FPG100 to 125 mg/dL
  • OGTT140 to 199 mg/dL

You should be tested for prediabetes if you are overweight or have obesity and have one or more other risk factors for diabetes, or if your parents, siblings, or children have type 2 diabetes. Even if you dont have risk factors, you should start getting tested once you reach age 45.
