What Is The Somogyi Effect

HIGH FASTING BLOOD SUGAR LEVELS EXPLAINED!

A second possible cause of high blood sugar levels in the morning is the Somogyi effect, sometimes also called rebound hyperglycemia. It was named after the doctor who first wrote about it.

If your blood sugar drops too low in the middle of the night while you are sleeping, your body will release hormones in an attempt to rescue you from the dangerously low blood sugar. The hormones do this by prompting your liver to release stored glucose in larger amounts than usual. But this system isnt perfect in a person with diabetes, so the liver releases more sugar than needed which leads to a high blood sugar level in the morning. This is the Somogyi effect.

Is Rice Good For Diabetes

People with diabetes can include rice as part of a healthful diet, but they should: Eat rice in moderation, and be mindful that 1 cup of rice contains 45 g of carbs. Spread their intake of rice and other carbs evenly throughout the day. Choose a variety of rice that is low in carbs and has a low GI score.

Why Is My Fasting Blood Sugar High During Pregnancy

During pregnancy, your placenta makes hormones that cause glucose to build up in your blood. Usually, your pancreas can send out enough insulin to handle it. But if your body cant make enough insulin or stops using insulin as it should, your blood sugar levels rise, and you get gestational diabetes.

    High Blood Sugar: Causes Complications And How To Lower Blood Sugar

    Your body breaks down glucose for energy using the insulin produced by the pancreas. This is required for our bodies to function. Illness can have an impact on the way our pancreas functions. Read this to learn how high blood sugar can affect your health.

    7 minute read

      Your body requires energy to function, and this energy comes from food. Specifically, your body breaks down glucose for energy using the insulin produced by the pancreas.

      Type 1 and type 2 diabetes cause impairment to this breakdown of sugar in the body, causing blood glucose levels to become irregular. When glucose is not broken down into energy, it can build up in the bloodstream and then becomes a health problem.


      Your pancreas produces insulin, which breaks down glucose. With type 1 diabetes, the cells that produce insulin are mistakenly attacked by your immune system. As a result of this autoimmune condition, blood sugar levels can become dangerously high without intervention.

      Type 2 diabetes occurs when your body no longer responds to insulin as well as it should and then also causes glucose to accumulate in the blood.

      A Little About Lada Latent Autoimmune Disease In Adults

      If all the information in this article hasnt helped you understand how blood sugar rises on a low-carb diet, and if your blood sugar rises not only in the morning but also at other times of the day, you may have a problem with latent autoimmune diabetes in adults , sometimes called type 1 diabetes.5

      Both Hallberg and Fung say they regularly see LADA patients who have been incorrectly diagnosed with type 2 diabetes.

      LADA is similar to type 1 diabetes in that antibodies attack the insulin-producing cells of the pancreas, but the disease occurs in adulthood rather than in childhood or adolescence. Diabetes researchers note that LADA also shows signs of type 2 diabetes, but patients tend to lose weight and need insulin faster because their insulin-producing beta cells have been attacked by the antibodies. The highest rates of LADA are found in Northern Europe, where up to 14% of people with type 2 diabetes actually have the disease.


      I test serum C-peptide and insulin in everyone who follows my crash diet, says Dr. Fung. I examine them over time, and it often takes 6 months to a year to make a definitive diagnosis. I suspect that about 5-10% of my type 2 patients are actually LADA patients. Dr. Nyman has a similar experience and routine.

      A Word About Lada Latent Autoimmune Diabetes In Adults

      If all of the information in this post does not help you understand your rising blood glucose on the low-carb diet, and your blood glucose continues to rise higher and higher, not only in the morning but at other times of day, there may be a potential issue of latent autoimmune diabetes in adults , also sometimes called type 1.5 diabetes.11

      Both Dr. Hallberg and Dr. Fung say they see LADA regularly among their patients who may have been misdiagnosed with type 2 diabetes and have LADA instead.

      LADA is like type 1 diabetes in that antibodies are attacking the insulin-producing cells of the pancreas, but it arises in adulthood, not in childhood or adolescence. Diabetes researchers note that LADA also has features of type 2 diabetes, but the patients usually are thinner and progress to needing insulin faster because their insulin-producing beta cells have been attacked by antibodies. The highest rates of LADA are found in Northern Europe, with up to 14% of those with type 2 diabetes actually having it.12


      I test serum C-peptide and insulin in everybody in my Intensive Dietary Management program, notes Dr. Fung. I re-check them over time and it often takes 6 months to 1 year to clinch the diagnosis. I would suspect about 5-10% of my type 2s are actually LADA.

      Dr. Naiman has similar experiences and routines.13

      How To Prevent Hyperglycaemia

      Complications Of High Blood Sugar

      Diabetes is one of the main causes of high blood sugar levels, but there are other causes that can impact your blood glucose and your risk for hyperglycemia.

      Hyperglycemia is the medical term for high blood sugar levels. You can have temporary spikes in blood sugar after eating a large meal or as a result of medication side effects. Chronically elevated blood sugar levels are dangerous and common in those with diabetes. Without treatment, you run the risk of a diabetic coma.

      Ketoacidosis is a condition that develops when elevated blood glucose levels go untreated. Without glucose to use for fuel, your body begins to burn fat instead and produces ketones. When there are too many ketones in the blood, it will turn acidic, which can very quickly lead to ketoacidosis, a diabetic coma, and even death.

      People without diabetes can develop a similar condition known as ketosis, but they can tolerate a certain level of ketones because inulin is still effectively working.

      Diabetic hyperosmolar syndrome is another serious complication of high blood sugar. This is more common among individuals with type 2 diabetes and is triggered by an infection or illness.


      As a result of the high blood sugar, your body tries to push out the excess glucose by passing it through your urine. Without treatment, this can result in life-threatening dehydration so prompt medical attention would be necessary.

      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.

      Whether you were recently diagnosed with type 2 diabetes or have been living with the condition for several years, you know how fickle blood sugar levels can be, and how important it is that they stay controlled.

      Proper blood sugar control is key for warding off potential diabetes complications, such as kidney disease, nerve damage, vision problems, stroke, and heart disease, according to the National Institutes of Health . Plus, keeping your levels in check on a daily basis can help you stay energized, focused, and in a good mood, explains Lisa McDermott, RD, CDCES, a diabetes specialist with the Pittsburgh-based Allegheny Health Network.

      According to the American Diabetes Association , proper medication, effective meal planning, regular exercise, and regular blood sugar checks can all help you keep your levels within a healthy range. The ADA recommends blood glucose stay within 80 to 130 milligrams per deciliter before meals and below 180 mg/dL two hours after the start of a meal. Furthermore, the organization recommends getting an A1C test, which measures your average blood glucose over the past two to three months, at least twice per year if your levels are stable and you are meeting treatment goals.

      Possible Ways To Try To Lower Fasting Levels

      Why Are My Fasting Blood Sugars So High?
      • Go for a walk after your evening meal exercise has a insulin type effect on the bodys cells which can impact many hours after and so may help lower fasting levels
      • Eat less carbohydrates in your evening meal although remember that it is important to still eat sufficient carbohydrates to avoid ketosis, so carbs must not be completely cut from the meal
      • Drink plenty of water take a glass of water to bed and have a drink when waking in the night
      • Eat a bedtime snack eating a snack before bed has been the biggest success with ladies in our support group. A snack which is high in protein and natural fat is believed to work best. Start with something like a couple of oatcakes and cheese, or a Ryvita with peanut butter. If this does not impact fasting levels, then try a high protein snack without the starchy carbohydrates
      • Apple cider vinegar drink 2 tbsp apple cider vinegar at bedtime with 1 oz of cheese. A small study9 in type 2 diabetic patients found that drinking 2 tbsp of apple cider vinegar and eating 1 oz cheese lowered fasting levels by 4%

      Some ladies with gestational diabetes have had great success with apple cider vinegar and so its worth trying if you have the stomach for it!


      Please note: As vinegar is acidic, it is advisable to dilute it in some water and brush teeth after consuming

      What Should My Blood Sugar Level Be

      When you’re first diagnosed with diabetes, your diabetes care team will usually tell you what your blood sugar level is and what you should aim to get it down to.

      You may be advised to use a testing device to monitor your blood sugar level regularly at home.


      Or you may have an appointment with a nurse or doctor every few months to see what your average blood sugar level is. This is known as your HbA1c level.

      Target blood sugar levels differ for everyone, but generally speaking:

      • if you monitor yourself at home with a self-testing kit a normal target is 4 to 7mmol/l before eating and under 8.5 to 9mmol/l 2 hours after a meal
      • if your HbA1c level is tested every few months a normal HbA1c target is below 48mmol/mol

      The Diabetes UK website has more about blood sugar levels and testing.

      What If My Fasting Blood Sugar Is 110

      A fasting blood sugar between 110 and 125 would be considered in the prediabetes range. Less than 110 is normal and greater than 126 is diabetes. These abnormal blood sugar levels usually happen when a persons tissues dont respond well to a hormone signal to take up sugar from the blood.

      A fasting blood sugar level of 100 to 125 milligrams per deciliter means you may have a common precursor to diabetes, called prediabetes.

      What Is The Dawn Phenomenon

      Your body uses glucose for energy and it is important to have enough extra energy to be able to wake up in the morning. So for a period of time in the early morning hours, usually between 3 a.m. and 8 a.m., your body starts churning out stored glucose to prepare for the upcoming day.

      At the same time, your body releases hormones that reduce your sensitivity to insulin. In addition, these events may be happening while your diabetes medication doses taken the day before are wearing off.

      These events cause your body’s blood sugar levels to rise in the morning .
