HOW DO YOU FEEL IF YOUR BLOOD SUGAR IS HIGH OR LOW?

Your doctor and your diabetes healthcare team are great sources of information if you need ideas and inspiration for taking care of your feet, quitting smoking, or staying on top of your numbers your weight, blood sugar, and other measures of health, such as blood pressure. Of course, if you notice any changes in your feet that concern you, its a good idea to see your doctor before your next regularly scheduled check-up.

Inspect Your Feet Every Day For Cracks Wounds And Sores

Nerve damage is a complication of diabetes that makes it hard to feel when you have sores or cracks in your feet. Patients with diabetes are looking for any changes in color, sores, or dry, cracked skin, says podiatrist Steven Tillett, DPM, of Portland, Oregon. Place a mirror on the floor to see under your feet or ask a friend or relative for help if you cant see all parts of your feet clearly.

Stabilize And Relieve Feet With Orthotic Shoes

Because wearing correct shoes is so important, orthotic footwear is a great investment in protection and comfort. Shoes made especially for people with diabetes are available at specialty stores and online, or you can visit your podiatrist for advice. Medicare Part B will cover one pair of extra-depth or custom-molded diabetic shoes a year, plus additional inserts to reduce pressure on your feet. Your doctor may recommend these shoes to you if you have an ulcer or sore that is not healing.

How Does Diabetes Affect Your Feet And Legs

If you’re managing diabetes, you may encounter problems with your feet and legs, two common complications of the disease. Diabetes puts you at higher risk for calluses, corns, bunions, blisters, and ulcers and high blood sugar means these minor injuries and alterations may become gateways to potentially disabling infections.

But you can take several steps to help keep your feet in good shape, including wearing specialized footwear, having regular foot exams, and performing low-impact exercise.

Why does this complication occur in the first place? First, know that high blood sugar levels damage nerves. Researchers arent exactly sure how this damage happens, but they think that blood sugar may have a negative effect on the nervous systems cells and enzymes, according to the Joslin Diabetes Center. These damaged nerves may lead to diabetic neuropathy, a condition in which you lose feeling in your feet or your hands.

According to the National Institute of Diabetes and Digestive and Kidney Diseases, neuropathy occurs in about 70 percent of people with diabetes, and its symptoms can result in harmful infections. After all, if you can’t feel your feet, you won’t be able to notice cuts, sores, or pain. And if you cant feel these irritations and wounds, they may lead to infection, and untreated infections can lead to gangrene, which in turn can require amputation.

When To Seek Medical Care

I would say that anybody with type 1 diabetes, first of all, they should always carry ketone sticks with them, says Dr. Hong. So, if blood sugars were to run high or they were to feel sickly, they should test their urine for ketones and if that is positive, they should seek care from a doctor or an emergency room. She says anyone should seek care if they feel very sick, have nausea, vomiting, severe abdominal pain, confusion, or trouble thinking clearly. And then, if they are checking blood glucoses and they notice that their sugars are running significantly higher than what they’re used to and it’s not responding to any of their usual care such as drinking water or taking their insulin, they should absolutely seek care and speak to the doctor as well, Dr. Hong adds.


When To See A Doctor

If youre experiencing one or many of these symptoms enough for it to raise a mental red flag or affect your life , thats a sign that you should talk to a doctor about your concerns. An expert like a primary care provider can help determine if high blood sugar due to diabetes or prediabetes is the cause of your symptoms. Even if youre not sure thats exactly whats going on, its still worth having a conversation with your doctor about hyperglycemia and other possible causes behind your symptoms.

    When It’s Time To Call A Doctor

    If any of the symptoms mentioned have begun to impact your life, such as fatigue so severe you can’t stay awake through the day, it’s a good idea to consult your physician. Dr. Fruge warns that “unstable blood sugar levels could put you at higher risk of heart disease and stroke and it is a red flag for serious health issues” — so blood sugar issues should be taken seriously.

    You should also see a doctor if you’re experiencing symptoms of hypoglycemia and haven’t been diagnosed with diabetes or any other underlying condition.

    If you do have diabetes and your hypoglycemia isn’t responding to the treatments described above, that’s another good cue to call your health care provider.

    If testing reveals you have Type 1 diabetes, you’ll need to continue to test your blood sugar levels as often as instructed by your physician, take insulin regularly and participate in regular exercise. This may mean you will need a new glucose monitoring system, so ask your doctor what they recommend. If you’re diagnosed with Type 2 diabetes, you’ll most likely need to do the same as for Type 1, as well as working with health care professionals to make lifestyle changes such as improving nutrition and planning workouts. Medication may be necessary as well.


    Healthy eating, regular exercise and other lifestyle changes can help alleviate symptoms and possibly even reverse prediabetes.

    Go Easy On Your Feet With Low

    People with diabetes benefit from exercise, but what is the best kind? While exercise for diabetes certainly isn’t one-size-fits all, be mindful that many fitness classes and aerobics programs include bouncing, jumping, and leaping, which may not be good for your feet. This is especially true if you have neuropathy. Instead, look into programs, such as walking or swimming, that dont put too much pressure on your feet. Just make sure you have the right shoe for whatever activity you choose.

    Why Am I Having Lows

    If you are experiencing low blood sugar and youre not sure why, bring a record of blood sugar, insulin, exercise and food data to a health care provider. Together, you can review all your data to figure out the cause of the lows.

    The more information you can give your health care provider, the better they can work with you to understand what’s causing the lows. Your provider may be able to help prevent low blood sugar by adjusting the timing of insulin dosing, exercise and meals or snacks. Changing insulin doses or the types of food you eat may also do the trick.


    Support Groups And Counseling For High Blood Sugar

    Hyperglycemia Vs. Hypoglycemia: Know The Difference

    You or family members may wish to join a support group with other people to share your experiences. The American Diabetes Association and the Juvenile Diabetes Research Foundation are both excellent resources. Your health care provider will have information about local groups in your area.

    Theres no one-size-fits-all recommendation for blood sugar control.

    The ADA says that a reasonable goal for many nonpregnant adults is to aim for an A1C level of less than 7. Yet some patients may be given a more stringent goal by their healthcare providers, such as 6.5, if thats reachable without harmful side effects, including hypoglycemia.


    On the other hand, if you are elderly, managing other health complications, or reliant on insulin, you may be given less stringent goals. It really becomes more important to just keep in the same place, says Rahil Bandukwala, DO, an endocrinologist at MemorialCare Saddleback Medical Center in Laguna Hills, California. Keeping A1C between 7.5 and 8.5 may be very reasonable for such a patient, Dr. Bandukwala adds, echoing the ADAs recommendations.

    Because elderly people are more likely to have blood sugar that swings too far downward, with fewer warning signs, managing their glucose too tightly can put them at greater risk for hypoglycemia, says Bandukwala. When you have low blood sugar, youre at a higher risk for becoming dizzy and falling or passing out, notes the ADA.

    Youre Getting Yeast Infections More Often Than Usual

    Hyperglycemia may lead you to get more frequent genital yeast infections. The culprit is often a type of yeast known as Candida albicans, per the ADA. According to the Centers for Disease Control and Prevention, in females the symptoms can include: vaginal itching, redness or soreness pain during sexual intercourse pain or discomfort during urination and thick, abnormal vaginal discharge. While yeast infections are common in people who dont have diabetes, having more glucose in your blood puts you at higher risk of getting them. The yeast feeds off the glucose, and if your blood sugar is high theres more glucose in the urinary tract, explains Bandukwala. Uncircumcised men with hyperglycemia are also at risk, he says.

    Were also seeing this happen a little more now with patients who take SGLT-2 inhibitors, which force the body to expel more glucose through the urine, the endocrinologist adds. The FDA has added a warning to the prescribing information for SGLT-2 inhibitors about a far more rare and potentially fatal genital condition, known as necrotizing fasciitis of the perineum, or Fourniers gangrene .

    The dangers of smoking run from your head to your feet. The chemicals in cigarette smoke damage and constrict your blood vessels, which means that if you smoke, you’re depriving your feet of the nutrient- and oxygen-rich blood that fights infection and keeps them healthy. Diabetic patients already have risk factors that compromise their blood vessels. Its never too late to stop smoking, says Tillett.

    Fingertips have more nerve endings, so this part of the finger tends to be the most sensitive.

    If you use a finger prick to check your blood sugar level, a few techniques can make the process less painful whether youre using a glucometer or a continuous glucose monitor.

    Blood sugar testing is crucial to diabetes management because high or low blood sugar can cause severe complications. If too much blood sugar accumulates in your bloodstream, you can experience major complications such as:

    • nerve damage
    • difficulty speaking
    • shaking

    Blood sugar can fluctuate throughout the day especially after meals, after exercising, and during stressful events. So its important to carefully monitor your blood sugar and keep it within a healthy range.

    A blood sugar level less than 140 milligrams per deciliter , but greater than 70 mg/dL is typically considered in the target range.


    You should check your blood sugar regularly, even if you arent experiencing symptoms of a high or low glucose level. Some people with high and low blood sugar dont have any symptoms.

      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.

        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.

        Think About What’s Going On

        Irene Dunbar, 73, of Durham, N.C., woke up one morning recently to discover her blood sugar was at 119, which is high for her. “I had a cold and had had orange juice yesterday and I normally do not drink orange juice and I thought, ‘I better not do that,'” she said.
