A Few Final Notes On Keeping Blood Sugar Stable

10 Alarming Signs Your Blood Sugar Is Too High

Taking an active, intentional approach to your blood sugar levels is crucial to your quality of life and overall health, ONeill says. Avoiding too-high or too-low blood sugar levels will help you avoid adverse symptoms and health complications, and staying within your target range can enable you to feel your best and do whatever you want to do in life, she says.

Test your blood sugar regularly, listen to your body, and dont ever hesitate to reach out to your doctor.

Slow Healing Of Cuts And Wounds

High blood sugar greatly slows the healing of skin and soft-tissue infections because neutrophils, the most common type of leukocyte in the immune systems arsenal, are particularly vulnerable to high levels of glucose. High blood sugar keeps the neutrophils from sticking to the endothelium, the inner lining of the blood vessels disrupts chemotaxis, the bodys chemical signaling control system that directs neutrophils to the site of injuries or infections and, as noted above, makes phagocytosis sluggish.


Another critical element of wound healing is a sufficient supply of oxygen, and the delivery of oxygen can be reduced by either peripheral neuropathy or peripheral vascular disease both common conditions caused by or made worse by high blood glucose.

The slow healing of wounds sets the stage for some of the grimmest diabetes complications. Minor wounds can advance to cellulitis, which is a serious infection. Cellulitis can advance to tissue necrosis, or tissue death. Tissue necrosis can then extend from the soft tissue into the bone, which is what often leads to amputation: Roughly 73,000 amputations are performed on people with diabetes in the United States each year.

The Classic Symptoms Of High Blood Sugar Are Polyuria Polydipsia And Polyphagia

In plain English, that means excessive urination, excessive thirst, and excessive hunger. Any doctor who hears this trio of complaints will reach for a blood glucose meter. But often, the person experiencing these symptoms doesnt notice them right away. This is partly because they often creep up on a person in a gradual fashion, and partly because the signs and symptoms of high blood glucose arent well known among people who dont have diabetes or dont know they have diabetes.

Headaches And Difficulty Concentrating

Acute hyperglycemia can cause headaches and difficulty concentrating in a fashion similar to polyphagia in which starving cells send out hunger signals because they cant access the glucose circulating in the blood.


Your brain is the biggest glucose hog around. If you dont believe it, consider that while the brain represents about 2 percent of your body weight, it devours fully 25 percent of the glucose you consume. And when brain cells have difficulty getting the fuel they need, they function poorly. This can cause problems with thinking, reasoning, and remembering, difficulty staying focused on tasks, and headaches.

Chronic high blood glucose can also lead to headaches, but by a different route. These headaches are often related to various types of nerve damage. Examples include occipital neuropathy, or damage to the optic nerve from elevated glucose levels, and a variety of diabetic mononeuropathies, which can affect specific cranial nerves, peripheral nerves, or nerve roots all of which can lead to headaches of varying intensities.

Correcting High Blood Sugar Levels With Insulin

7 Sneaky Signs Your Blood Sugar May Be Too High â Healthy ...

If you take insulin, one way to reduce blood sugar is to inject insulin.

However, be careful as insulin can take 4 hours or longer to be fully absorbed, so you need to make sure you take into account how much insulin you may already have in your body that is yet to be absorbed by the blood. Insulin that is yet to be absorbed by the blood is called active insulin.

If you decide to correct with insulin, watch you dont over correct as this can lead to hypoglycemia and can be dangerous, particularly so before bed.

How Are High Blood Sugar Levels Treated

To treat high blood sugar, it helps to know what is causing it. You might need to take more insulin or diabetes pills because youre growing and eating more food, or you might need to get more exercise each day.

Having high blood sugar levels every once in a while isnt a big deal. It happens to everyone with diabetes from time to time. But if your blood sugar levels are high a lot, your diabetes health care team will have to help you figure out how to get them back to a healthy level.

Signs And Symptoms Of High Blood Sugar To Be Aware Of

    Blood sugar is our source of energy, and we need it to function, but in some people, it can reach excessive levels.

    High blood sugar is a major problem. It could increase the risk of heart disease, heart attack, stroke, and kidney damage. Hyperglycemia increases glycation. This leads to the production of harmful particles. These particles impair the functions of glycated substances.


    A chain of reactions takes place. It leads to problems with blood flow, inflammation, slow wound healing. Keeping blood sugar levels in check is vital for good health and diabetes prevention.

    How High Is Too High For A Blood Sugar Reading And What Are The Dangers

    What is A Normal Blood Sugar Level & Signs Of It Being Too High! | Dr. Nick Z.

    A high blood sugar level is defined as a reading of greater than 130 mg/dL after 8 hours of fasting or a reading of greater than 180 mg/dLafter eating a meal, according to WebMD. Frequent high blood sugar can cause damage to the nerves, blood vessels and other organs.

    Although diabetes is the most common reason for high blood sugar, there are many other causes, such as infection, injury or even just eating more sugar than normal, notes MedicineNet. When symptoms such as increased thirst, increased urination and weight loss accompany high blood sugar, diabetes is diagnosed, states WebMD.


    High blood sugar coats blood cells, which in turn causes the cells to hinder circulation, explains the Mayo Clinic. The small blood vessels are particularly susceptible to these problems, so damage to the eyes, kidneys and feet are common in those with chronically high blood sugar. Controlling high blood sugar can prevent or lessen complications such as heart attack, stroke, eye damage that can lead to blindness, nerve damage in the hands and feet, kidney damage, gum disease and tooth loss. Damage can begin when blood sugar is higher than normal, but not high enough to be considered diabetes. Increasing physical activity and losing weight can help decrease blood sugar in people who are at risk for developing diabetes.

    One of the challenges of managing diabetes is maintaining consistent blood sugar levels. Even with diligence, some situations can cause high blood sugar, or hyperglycemia, while others can bring on low blood sugar, or hypoglycemia.

    After all, its not just carbohydrate intake that influences the amount of glucose coursing through your bloodstream when you have type 2 diabetes. Emotional stress and certain medications can increase your blood sugar levels, and a boost in activity can cause it to drop, says Megan ONeill, CDCES, a medical science liaison for diabetes care at Abbott healthcare company in Monterey, California. Sometimes people experience a spike in their blood sugar early in the morning due to the dawn effect, a temporary surge of hormones that occurs as the body prepares to wake, according to the Cleveland Clinic.


    For people with diabetes, managing blood glucose levels is especially important, ONeill says. Levels that are too low or high can result in complications that affect your kidneys, heart, and vision, reduce your quality of life, require expensive interventions, or even be fatal.

    Low Blood Sugar Chart And Action Plan

    Low blood sugar is also called hypoglycemia. The numbers below represent values in the hypoglycemic range and require action to bring blood sugar levels up into a normal range.

    Alert Level and Treatment Plan
    50 mg/dL or underRed Flag: Blood sugar is critically low and requires immediate treatment.

    If a person is unable to speak and/or is not alert, treat with glucagon via injection or nasal spray. Call emergency medical response if necessary. Do not place food or drink into the mouth.

    If a person is alert and able to speak clearly, treat with 15 grams of rapid-acting carbohydrate such as glucose gel, 4 oz regular soda, or fruit juice. Re-test blood sugar in 15 minutes and repeat as needed to bring blood sugar within range.

    51-70 mg/dLRed Flag: Blood sugar is below normal levels and requires immediate treatment.

    Treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes. Repeat treatment as needed to bring blood sugar within range.

    71-90 mg/dLYellow Flag: Blood sugar levels should be watched and treated as needed.

    If youre having symptoms of low blood sugar, treat with 15 grams of rapid-acting carbohydrate and re-test in 15 minutes.

    Repeat treatment or follow with a meal. If it is meal time, move forward with eating the meal. People often fall into this range when they are late for a meal or have been especially active.

    How Can I Treat And Manage Hyperglycemia

    Symptoms of high blood sugar

    People with both type 1 and type 2 diabetes can manage hyperglycemia by eating healthy, being active, and managing stress. In addition, insulin is a critical part of managing hyperglycemia for people with type 1 diabetes, while people with type 2 diabetes may need oral medications and eventually insulin to help them manage hyperglycemia.

    If you dont have diabetes and have any of the signs and symptoms of hyperglycemia, call your healthcare provider. Together you can work to manage your hyperglycemia.

    Reflect On The Amount Of Sugar In Your Diet

    Hyperglycemia occurs when there is too much glucose in the blood.

    Therefore, one way of reducing your blood glucose levels is reflecting on where sugar may be consumed in the diet. Think about any refined and processed foods that may be in your diet as these are often high in sugar. This can be achieved through a low carbohydrate diet.

    How Do You Feel When Your Blood Sugar Is Too High

    Here are some of the complaints that you may feel when your blood sugar is too high,

    • Headache and body aches
    • Loss of consciousness, coma or a seizure
    • Difficulty in concentration

    These symptoms can go on for a while till some food containing sugar is given. If this continues for long without any intake of sugar or any carbs, the condition can worsen and the blood sugar levels may further drop down, leading to complications. Very low blood sugar level can be a medical emergency too, which is why it is very important to be aware of the symptoms coming up because without an immediate treatment the patient can faint, may experience a seizure, or can even go into a coma.

    Both the high and the low blood sugar level can lead to an emergency, and therefore knowledge of how do you feel when your blood sugar is too high or low is very necessary. Early you come up with a solution faster the condition can be eased and the complication can be avoided.
