Why Do I Have Low Blood Sugar After Eating
In fasting hypoglycemia, a person gets low blood sugar if they havent eaten for a while. Reactive hypoglycemia is low blood sugar that occurs after eating, usually due to eating a meal high in carbohydrates. This causes the blood sugar to rise rapidly, which in some cases may stimulate excess secretion of insulin.
Is 141 Blood Sugar High In The Morning
Normal is below 140 mg/dl Pre-diabetes is 141-199 mg/dl Diabetes is above 200 mg/dl. How is Pre-diabetes different from diabetes? Pre-diabetes is a way to explain higher than normal blood sugar levels. When a persons blood sugar levels are higher than normal but not high enough to be diabetes it is pre-diabetes.
Blood Sugar Levels Before And After Eating
Blood sugar levels in our bodies will fluctuate depending on various conditions and circumstances. Here are the different levels:
1. Normal Blood Sugar Levels After Eating
According to the American Diabetics Association, normal blood sugar levels after meals should be 70 mg/dl 140mg/dl.This should be the reading 2 hours after a meal. If the levels are lower than 70mg/dl, it might mean that you have hypoglycemia. If your blood sugar is slightly higher than 140mg/dl, it does not necessarily mean that you have diabetes. However, you might need to have an oral glucose tolerance test later on to determine the severity of your elevated post-meal blood sugar.
2. Normal Levels of Fasting Blood Sugar
This blood sugar level is taken first thing when you wake up before your first meal. A normal level of fasting blood sugar lies from 70mg/dl to 92mg/dl. This is also the blood sugar level for a normal person who has not eaten for the past few hours.
3. Normal Blood Sugar Level for Type 1 Diabetics
American Diabetes Association recommends that blood sugar targets should lie between the following:
Before eating your blood sugar should be:
- Adults: 90-130mg/dl
After 1 to 2 hours after meals, your blood sugar should be:
- Adults: less than 180mg/dl
When going to bed, your blood sugar should be:
- Adults: 90-150mg/dl
4. Normal Blood Sugar Level for Type 2 Diabetics
American Diabetes Association recommends the following blood sugar targets for people with type 2 diabetes:
- Adults: 70-130mg/dl

Why You Shouldnt Lower Your A1c Too Quickly
It can be a good idea to approach lowering your A1c with a bit of caution. Just as crash dieting isnt healthy, there can be some serious health risks associated with lowering your A1c too quickly. I turned to Dr. Peters for an explanation:
If you lower your A1c too quickly, many bad things can happen. First, weight gain and total body swelling. Next, it can cause bleeding in the retina which can lead to blindness, and third, it can cause painful neuropathy that never goes away. Its slightly different for newly diagnosed patients, but, in general, no one should try to go from an A1c of 10% to 6% quickly. Take slow steps. Wanting to get to a low number very fast only causes harm. Diabetes is a long-term disease, so slow steps to establish new habits that can last a lifetime is the way to go. Anything too sudden and the body reacts badly.
High Blood Sugar Prevention
- Learn about managing diabetes.
- Work with a certified diabetes educator. This person will have a CDE certification and may work in a diabetes education center or hospital.
- Check blood sugar as directed by a CDE and doctor or nurse.
- Know the symptoms and act quickly before blood sugars get out of control.
- Follow a diabetes diet plan. Adjust the plan as needed.
- Take medications for diabetes as directed by your healthcare professional.
- Exercise daily.

Fasting Blood Glucose Level Test Preparation
What should you do if your doctor orders a fasting blood sugar test? The preparation is the same as when you take a fasting test for cholesterol. First, be sure to find out if you need to schedule an appointment for your test . Ask your doctor what time is best to take it.
- Schedule your test if necessary
- Ask your doctor if you need to change any of the medications you take on the morning of the test
- If you normally drink coffee or have caffeine, ask your doctor if that is okay. It may not be, since it affects blood sugar levels
- Fast for at least 8 hours before your test. Usually, an overnight fast is most convenient
- You can drink water
When Should I Check My Blood Sugar
How often you check your blood sugar depends on the type of diabetes you have and if you take any diabetes medicines.
Typical times to check your blood sugar include:
- When you first wake up, before you eat or drink anything.
- Before a meal.
- Two hours after a meal.
- At bedtime.
If you have type 1 diabetes, have type 2 diabetes and take insulin, or often have low blood sugar, your doctor may want you to check your blood sugar more often, such as before and after youre physically active.

How Do I Check My Blood Sugar
You use a blood glucose meter to check your blood sugar. This device uses a small drop of blood from your finger to measure your blood sugar level. You can get the meter and supplies in a drug store or by mail.
Read the directions that come with your meter to learn how to check your blood sugar. Your health care team also can show you how to use your meter. Write the date, time, and result of the test in your blood sugar record. Take your blood sugar record and meter to each visit and talk about your results with your health care team.
What Foods Block Sugar Absorption
If you are diagnosed with diabetes, it is important that you maintain a steady blood sugar level and certain foods can help you do just that.
- Whole Grains like bran, barley and rye. Barley.
- Nuts like almonds, walnuts and pistachios.
- Apple Cider Vinegar.
- Non Starchy vegetables such as broccoli, cucumber and carrots.

Whats A Spike And Why Do They Happen
After-meal, or postprandial, spikes are temporary high blood glucose levels that occur soon after eating. It is normal for the level of glucose in the blood to rise a small amount after eating, even in people who do not have diabetes. However, if the rise is too high, it can affect your quality of life today and contribute to serious health problems down the road.
Your Blood Sugar Isnt Just Because Of What You Eat
Mainstream media would have you believe that your blood sugar levels are impacted only by what you eat and how much you exercise, but people with type 1 and type 2 diabetes who test their blood sugars frequently could tell you otherwise.
Its especially important to keep this mind when looking at your own blood sugars and your goals because there are certain variables and challenges that impact blood sugar levels that you cant always control.
- Menstrual cycles: raises blood sugar and insulin needs
- Adrenaline rushes from competitive sports, heated arguments, rollercoaster rides: raises blood sugar and insulin needs
- The common cold and other illnesses: usually raises blood sugar and insulin needs
- Hormonal changes due to puberty and healthy growth in young adults: raises blood sugar and insulin needs
- An injury which raises overall inflammation levels: raises blood sugar and insulin needs
- Glucogenesis during anaerobic exercise: raises blood sugar
While you cant necessarily prevent these factors that affect your blood sugar from occurring, you can work with your diabetes healthcare team to adjust your insulin, other diabetes medications, nutrition and activity levels to help compensate for them when they do occur.
For example, when engaging in anaerobic exercise like weightlifting many people with type 1 diabetes find it necessary to take a small bolus of insulin prior to or during their workout because anaerobic exercise can actually raise blood sugar.

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

The reason blood glucose tends to spike after eating in many people with diabetes is a simple matter of timing. In a person who doesnt have diabetes, eating foods containing carbohydrate causes two important reactions in the pancreas: the immediate release of insulin into the bloodstream, and the release of a hormone called amylin. The insulin starts working almost immediately and finishes its job in a matter of minutes. The amylin keeps food from reaching the small intestine too quickly . As a result, the moment blood glucose starts to rise, insulin is there to sweep the incoming glucose into the bodys cells. In most cases, the after-meal blood glucose rise is barely noticeable.
However, in people with diabetes, the situation is like that of a batter with very slow reflexes facing a pitcher who throws 98-mph fastballs: The timing is all fouled up. Rapid-acting insulin that is injected at mealtimes takes approximately 15 minutes to start working, 6090 minutes to peak, or reach maximum effectiveness, and four hours or more to finish working. Meanwhile, amylin is either produced in insufficient amounts or not at all, so the movement of food from the stomach to the intestines is not slowed the way it should be. As a result, food digests even faster than usual. This combination of slower insulin and faster food can cause the blood glucose level to rise quite high soon after eating. Once the mealtime insulin finally kicks in, the high is followed by a sharp drop.

High Blood Sugar: Hidden Dangers
In the short term, high blood sugar levels can zap your energy, cause excessive thirst and urination, and blur your vision. High blood sugar levels can also lead to dehydration, dry and itchy skin, and infections. Minimizing the time spent above your target blood sugar range can help you feel your best and will help prevent complications and injury to your body.
Over time, high blood sugar affects many parts of the body. Chronic high blood sugar can start to cause noticeable changes, including:
- Memory problems
- Vision problems like blurriness, diabetic retinopathy, and blindness
- Gum disease that leads to tooth loss, which can make eating healthy foods difficult due to problems chewing
- Heart attack and stroke due to increased plaque build-up in the vessels and other vascular issues
- Kidney disease, which can lead to the need for dialysis or a kidney transplant
- Nerve damage that can cause decreased sensation in the feet and legs which increases the risk for wounds to turn into serious infections and even amputation
Nerve damage from high blood sugar can also cause a variety of symptoms including:
- Pain and tingling in the feet and hands
- Difficulty emptying your bladder
- Problems during the digestion process after eating, which can cause food to sit in the stomach too long and lead to nausea, vomiting, and erratic blood sugar levels
Checking your blood sugar frequently and taking immediate action when it is above range can reduce your risk of complications.
Normal Blood Sugar Levels In Children
Younger than 6 years old mg/dL
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.

Identify The Main Pain Points
Whether you are self-managing your diabetes or work closely with your medical team, the first step should always be to try to identify the main pain points or reasons why your A1c is higher than youd like. The only real way of doing this is by tracking your blood sugars very closely.
If you wear a Continuous Glucose Monitor, you can look at your 7-day, 30-day, and 90-day data to see if you can spot any trends. For example, you might find that you are running high from 1-5 AM every night, every morning or every day after meals. Or perhaps you always go low after exercise. We all have different blood sugar patterns.
Its also very possible that you simply are running your blood sugar a little too high all the time and could benefit from adjusting your diabetes medication. Identifying patterns like that makes it possible to pinpoint areas of potential improvement so you can start making a plan for how to limit your high and low blood sugars.
If you rely on manual blood sugar testing, its a little trickier since most people dont test every five minutes. What I would recommend is increasing how often you test for a while, and maybe even test during the night if you wake up anyway. Most meters allow you to download data to your computer, or you can upload the data to app-based platforms like One Drop or mySugr. This can help you see the data in a more cohesive way so you can start looking for trends.
Prevention Of Low Blood Sugar
Do not skip or delay meals. If your diet plan includes snacks, make sure to take these.
Measure insulin dosage carefully and inject it properly. If you cannot see well, a family member or a visiting nurse can prepare your insulin injections for you.
Take only the prescribed amount of insulin or oral medication for diabetes that your doctor has ordered.
Keep exercise consistent from day to day. Eat a snack or reduce your insulin prior to unusual exercise.
If you are taking insulin, notify your doctor if you have low blood sugars four or more times per week or if you have a severe low blood sugar. Severe low blood sugars are those less than 40 mg., those requiring help from another person, or those which cause you to have a convulsion or become unconscious.
If you are taking oral medication for your diabetes notify your doctor or nurse if blood sugars are running less than 80 mg. or if you have a severe low blood sugar.
