Giving Asprosin Time Off

What should be the blood sugar levels after 30 mins of food intake? – Dr. Mahesh DM

The team confirmed the benefits of giving asprosin time off.

They used a special monoclonal antibody, designed to interfere with asprosins ability to do her job, in mice suffering from metabolic troubles, it HELPED.

It stabilized glucose and it lowered insulin.

So what does it mean for you ?

How Food Affects Blood Sugar

When you eat food, your body breaks it down into essential parts:

  • Carbohydrates
  • Fats
  • Vitamins and minerals

All parts are necessary in a healthy diet, but the three types of carbohydrates are particularly important when it comes to your blood glucose level. While the general rule is that the more carbohydrates you eat, the higher your blood sugar level, not all three types of carbohydrates convert to blood sugar at the same rate.

The foods that fit into each carb category include:

  • Starches, or complex carbohydrates: Starchy vegetables, dried beans, and grains
  • Sugars: Fruits, baked goods, beverages, and processed food items like cereals or granola bars
  • Fiber: Whole wheat products, chickpeas, lentils, berries, pears, and brussels sprouts

The glycemic index helps you find out which foods can increase or help decrease blood sugar levels. Based on a scale ranging from 0 to 100, high-indexed foods are rapidly digested, absorbed, and metabolized, resulting in marked fluctuations in blood sugar levels, while low-indexed foods produce smaller fluctuations in your blood glucose.

The American Diabetes Association advises adding lean sources of protein and heart-healthy fats to help reduce the overall glycemic impact of a meal or snack.

Hba1c Test For Diabetes Diagnosis

An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.

Indications of diabetes or prediabetes are given under the following conditions:

  • Normal: Below 42 mmol/mol
  • Prediabetes: 42 to 47 mmol/mol
  • Diabetes: 48 mmol/mol

There are two types of blood sugar levels that may be measured. The first is the blood glucose level we get from doing finger prick blood glucose tests. These give us a reading of how high our levels are at that very point in time.

The second is the HbA1c reading, which gives a good idea of our average control over a period of 2 to 3 months. The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children.

Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol .

Research has shown that high blood glucose levels over time can lead to organ and circulation damage.

Keeping blood glucose above 4 mmol/l for people on insulin or certain medications for type 2 diabetes is important to prevent hypos occurring, which can be dangerous.

Your doctor may give you different targets. Children, older people and those at particular risk of hypoglycemia may be given wider targets.

Cgm Studies In Nondiabetic Individuals

One study from 2009 entitled Reference Values for Continuous Glucose Monitoring in Chinese Subjects looked at the glucose levels of 434 healthy adults using CGM and found the following:

  • On average, their daily glucose levels stayed between 70140 mg/dl for 93% of the day, with very small portions of the day spent above 140 mg/dl or below 70 mg/dl.
  • Also, their mean 24-hour glucose levels were around 104 mg/dl
  • 1-hour post-meal glucose values average 121-123 mg/dl for breakfast, lunch, and dinner
  • 3-hour post-meal glucose values were around 97-114 mg/dl.
  • Peak post-meal values appeared to be around 60 minutes after eating.
  • Mean fasting glucose was 86 ± 7 mg/dl.
  • Mean daytime glucose was 106 ± 11 mg/dl.
  • Mean nighttime glucose was 99 ± 11 mg/dl.

A 2010 study, Variation of Interstitial Glucose Measurements Assessed by Continuous Glucose Monitors in Healthy, Nondiabetic Individuals, looked at a healthy population of 74 individuals that included children, adolescents, and adults during daily living using CGM. This research showed that:

  • Glucose levels stayed between 71-120 mg/dl for 91% of the day.
  • Levels were lower than 70 mg/dl for 1.7% of the time and greater than 140 mg/dl, only 0.4% of the time.
  • Mean 24-hour glucose was 98 ± 10 mg/dl.
  • Mean fasting glucose of 86 ± 8 mg/dl.

Compared to the first study mentioned, these healthy, nondiabetic individuals appeared to have a tighter range of glucose, spending the vast majority of the 24-hour period between 71-120 mg/dl.

Whats Your Risk Of Death From Undiagnosed High Blood Sugar

Low GI Diet

This old it may be, did demonstrate that the relative risk of death from heart disease and strokes increases by 1.5 times when your blood glucose after 2 hours post 75gms glucose test is between 140mg/dl 200mg/dl . See Red arrow in Chart below.

I want that figure to sink in for a moment. People who have a result between 140mg/dl 200mg/dl are not considered diabetic but prediabetic. That piece of research is telling us the risk of death of prediabetics is already high.

The sad thing is that millions of people like you and I are walking around not knowing that we may have pre-diabetes simply because we have not been tested.

and also because we do not show any symptoms.

Worse still is, that same research does tell us if you your blood sugar is above 200mg/dl your relative risk of death actually doubles.

John Fuller several years ago also did a classic piece of research where he gave 18,403 British men aged between 40 60 years of age 50gm of glucose load. John secured the results of the test and just simply followed the individuals up for 7.5 years to see what their mortality risk was over time.

He wanted to know if increases in blood glucose after 2 hours of the 50gm glucose load would be a risk factor for heart disease or death.

John and his colleagues found the men who had 2-hour blood glucose levels below 96mg/dl did not suffer any significant mortality.

How Long After Eating Does Blood Sugar Return To Normal

The blood sugar level falls back to a normal level around 1-2 hours after taking food. During this time digestion slows down and the sugar is absorbed by the tissue.

In diabetics, there can be a sudden spike in blood sugar after eating causing headache, dizziness and discomfort. This is called a post-prandial reaction. Normally, taking prescribed insulin medication can help mediate this problem.

Normal Blood Sugar Levels In Children

Younger than 6 years old mg/dL

Bedtime100-140

Adults who are 20 years or older will have blood sugar levels that range between less than 100-180 mg/dL over the course of a day. When you wake up in the morning, your fasting blood sugar should be at its lowest because you havent consumed food for about eight hours. If youre an adult and struggling with glucose control, your healthcare provider can help you develop a treatment plan to manage your blood sugar better.

Blood glucose levels outside the ranges listed above are categorized as either high or low blood sugar. Blood sugar levels are considered high if theyre over 130 mg/dL before a meal or 180 mg/dL within one to two hours after a meal. Many people wont start to experience symptoms from high blood sugar until their levels are at 250 mg/dL or higher. The highest blood sugar level thats considered safe will depend on the person and whether they have diabetes, but will typically be between 160 to 240 mg/dL.

Recommended Blood Sugar Targets

For people with type 1 diabetes, the American Diabetes Association recommends that blood sugar targets be based on a person’s needs and goals. Talk to your doctor and diabetes educator about these goals. A general guideline is:

Before meals, your blood sugar should be:

  • From 90 to 130 mg/dL for adults
  • From 90 to 130 mg/dL for children, 13 to 19 years old
  • From 90 to 180 mg/dL for children, 6 to 12 years old
  • From 100 to 180 mg/dL for children under 6 years old

After meals , your blood sugar should be:

  • Less than 180 mg/dL for adults

At bedtime, your blood sugar should be:

  • From 90 to 150 mg/dL for adults
  • From 90 to 150 mg/dL for children, 13 to 19 years old
  • From 100 to 180 mg/dL for children, 6 to 12 years old
  • From 110 to 200 mg/dL for children under 6 years old

For people with type 2 diabetes, the American Diabetes Association also recommends that blood sugar targets be individualized. Talk to your doctor and diabetes educator about your goals.

In general, before meals, your blood sugar should be:

  • From 70 to 130 mg/dL for adults

After meals , your blood sugar should be:

  • Less than 180 mg/dL for adults

What Are Blood Sugar Targets

Clearing Up Myths About Blood Sugars After Eating

A blood sugar target is the range you try to reach as much as possible. These are typical targets:

  • Before a meal: 80 to 130 mg/dL.
  • Two hours after the start of a meal: Less than 180 mg/dL.

Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

Why You Should Keep An Eye On It

When your blood sugar is high, you can get symptoms like a foggy-headed feeling that makes it hard to focus or think clearly. Your energy may also take a dive, and you may feel nervous or moody.

If your levels go too low, you could even pass out. In the long run, if your blood sugar stays up, you could be at risk for heart disease, stroke, kidney disease, or other problems.

Translating Your A1c To A Blood Sugar Level

Using this easy calculator from the ADA, you can translate your most recent A1C result to an eAG or estimate average glucose level.

You can also use this translation when working to improve your A1c and achieving closer to normal blood sugar levels. If you know an A1c of 6.5 is an average blood sugar level of 126 mg/dL or a range of 100 to 152 mg/dL, then you can look at your current blood sugar results on your CGM and meter and pinpoint which time of day youre frequently higher than this range.12% = 298 mg/dL or range of 240 347 11% = 269 mg/dL or range of 217 31410% = 240 mg/dL or range of 193 2829% = 212 mg/dL or range of 170 2498% = 183 mg/dL or range of 147 2177% = 154 mg/dL or range of 123 1856% = 126 mg/dL or range of 100 1525% = 97 mg/dL or range of 76 120

Normal blood sugar levels in a person without diabetes can result in an A1c as low as 4.6 or 4.7 percent and as high as 5.6 percent.

Just a decade or two ago, it was rare for a person with type 1 diabetes to achieve an A1c result below 6 percent. Thanks to new and improved insulin and better technology like continuous glucose monitors and smarter insulin pumps, more people with diabetes are able to safely achieve A1c levels in the higher 5 percent range.

Blood Sugar Level Immediately After Eating:

Blood sugar level changes rapidly according to the intake of the meal. The normal blood sugar level before eating or during fasting is between 3.5 to 6.1 mmol/L.

Normal blood sugar right after eating rises drastically as the digestive tract acts quickly to digest the food through mechanical actions, digestive enzymes and different hormones. So the blood glucose rises sharply during this time. The rate at which the blood sugar rises depends on the type of food, the amount is taken, the metabolic condition of the individual, etc.

Diabetic Ketoacidosis: A Complication Of Severe Hyperglycemia In Type 1 Diabetes

Blood Sugar Levels Chart

In addition to the complications above, severe hyperglycemia in people with type 1 diabetes can lead to a dangerous condition called ketoacidosis, mentioned above. This condition develops when toxic acids called ketones build up in the blood. It can become serious and lead to diabetic coma or even death. According to the American Diabetes Association, ketoacidosis affects people with type 1 diabetes, but it rarely affects people with type 2 diabetes.

How Do I Check Blood Sugar Level

Checking blood sugar level is very simple thanks to the availability of easy-to-use handheld glucometers. These consumer glucometers have made it very easy to always keep an eye on your blood sugar level. They are an absolute essential for diabetics and also for people trying to maintain their blood glucose level.

They operate by taking pin-pricks of blood onto a small electrode slip, which when inserted into the device gives a digital readout of the amount of glucose content in the blood. These devices have become extremely popular for their convenience, reliability and accuracy.

An essential laboratory test of blood glucose level is the Oral Glucose Tolerance Test or OGTT. It is a diagnostic test for DM or any glucose intolerance. Here, a blood sugar reading is taken after a 10-12 hour fast. Then another reading is taken after 2 hours after ingesting a measured amount of glucose. This test shows the bodys ability to absorb glucose, thus is a confirmatory test for DM.

What Is Diabetic Ketoacidosis

If you think you may have low blood sugar, check it even if you dont have symptoms.

When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:

  • Fast, deep breathing.
  • Nausea and vomiting.
  • Stomach pain.

If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.

DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.

Why Is It Important To Reduce The Size And Duration Of These Spikes

Reducing these spikes may help you to increase the amount of time you spend in your target blood sugar range , which will have a positive impact on your future health. You should consult your healthcare team to understand the best target range for you, as this will differ from person to person. However, the International Society for Paediatric and Adolescent Diabetes recommends a target of 5.0-10.0 mmol/L .

Symptoms of a high blood sugar level also vary in individuals, but they may cause you to feel thirsty, tired, stressed and need to go to the toilet a lot. In the short term, by avoiding prolonged high blood sugar readings after eating, you should also reduce the occurrence of these symptoms and improve your energy, cognitive and athletic ability and overall mood.

Normal Blood Sugar Levels Vs Hyperglycemia

Blood Sugar Levels After Eating

If youve been diagnosed with diabetes, your endocrinologist will tell you what your target blood glucose levels are. Your levels may be different from what is usually considered as normal because of age, pregnancy, or other factors. You will be given two target levels, or ranges, one applying to when you haven’t eaten for a number of hours and one for after meals .

The Nuances Of Low Glucose

In a recent study, researchers reviewed the published literature to see if low fasting glucose levels affected healthy peoples long term risks of health problems, like strokes and heart attacks. They found that healthy non-diabetic people who had baseline fasting glucose levels of less than 72 mg/dl had a 56% increase in all-cause mortality compared to people with normal fasting blood glucose levels. Also, the risks for heart attacks and strokes were higher in people with baseline fasting glucose levels less than 72 mg/dl. This result is likely due to the body releasing more epinephrine to counteract the low glucose levels too much epinephrine for too long leads to heart problems. Interestingly, people with low fasting glucose levels of less than 83 mg/dl but higher than 72 mg/dl did not have an increased risk of future heart attacks and strokes.

While there has been an association between low fasting plasma glucose levels and worse health outcomes, it is not clear whether transient dips in glucose levels during a continuous 24-hour period are unhealthy for nondiabetic individuals. Part of the reason that this is unknown is that continuous glucose monitoring is a relatively new technology and has been studied more extensively in diabetic individuals than in healthy individuals.

Expected Results In Diabetics

Diabetics experience larger spikes in blood glucose that take longer to return to baseline. For diabetics, blood glucose an hour after eating should remain below 180 mg/dL or no more than 80 mg/dL over your pre-meal levels. The highest spikes in blood glucose levels often occur after breakfast. If you experience hypoglycemia, or low blood glucose levels before a meal, you might experience a higher-than-normal spike over baseline levels this doesn’t necessarily indicate an abnormal rise.
