Your brain requires a combination of minerals and nutrients that help convert glucose and ketones into energy. If your physical energy feels fine but your brain energy and focus is suffering, your diet may be missing nutrients like vitamin B12, vitamin B6, omega-3 fatty acids, vitamin D and vitamin C. Having inadequacy of these vitamins in your diet can lead to brain fog and low cognitive function.

  • Test your blood sugar after 10 minutes if its improved and you feel better, move on to step 3. If theres little or no change, treat again with a sugary drink or snack and take another reading after 10 to 15 minutes.

    When Is It Good To See A Healthcare Provider

    Its usual to feel exhausted now and again, but if fatigue persists longer than 2 weeks, it can be a good time to visit a healthcare provider. For people who also experience signs of blood glucose spikes like an enhanced thirst, urinating often, nausea, drowsiness, or fatigue could be an indication that they have developed or are at risk of developing diabetes. For people who already are diabetic, regular appointments for regulating their blood glucose and managing their diabetes are very vital since these signs can indicate that their current treatment plan is no longer effective.

    Diabetes fatigue management is very important for those with both type 1 and types 2 diabetes. It might be troublesome to manage the condition, particularly at first, but not unfeasible. The best approach to manage signs or complications of the medical condition is to book an appointment with a diabetes specialist as they can aid in tacking fatigue and other signs by including certain lifestyle changes.


    High glucose levels in the blood can have dangerous consequences if left untreated. Diabetics already are aware of the outcomes of high blood sugar all too well, but for those who are unaware, it may be difficult to pin down the risk of developing the condition or illnesses that follow it like fatigue.

    Avoid Eating Sugary Foods

    If eating sugary foods really makes you feel tired, then maybe giving up those treats is best for now! There are plenty of healthy snacks out there that will keep you satisfied without sabotaging your energy levels. If your sweet tooth makes treats too hard to resist, plan out your meals for the day and try to include no more than one serving of a sweet treat . Or have a piece of fruit, which will give you that sweet taste of sugar but along with fiber that slows down absorption of the sugar into your bloodstream.

    How Does Diabetes Affect Sleep


    Its estimated that one in two people with type 2 diabetes have sleep problems due to unstable blood sugar levels and accompanying diabetes-related symptoms, High blood sugar and low blood sugar during the night can lead to insomnia and next-day fatigue. As with many chronic conditions, feelings of depression or stress about the disease itself may also keep you awake at night.

    When blood sugar levels are high, the kidneys overcompensate by causing you to urinate more often. During the night, these frequent trips to the bathroom lead to disrupted sleep. High blood sugar may also cause headaches, increased thirst, and tiredness that can interfere with falling asleep.

    By contrast, going too many hours without eating or taking the wrong balance of diabetes medication can also lead to low blood sugar levels at night. You may have nightmares, break out into a sweat, or feel irritated or confused when you wake up.

    Talk to your healthcare provider if you are experiencing fatigue, trouble sleeping, or any other worrying symptoms. They can help analyze the reason and work with you to keep your blood sugar levels more stable.

    What Causes Fatigue In Diabetes

    Why does too much sugar make you tired? With diabetes, tiredness can result as a result of several factors such as:

    • Can insulin resistance cause fatigue? High levels of glucose in the blood, either due to a lack of insulin or due to insulin resistance, can have an effect on the bodys capacity to get sugar from the blood into body cells to meet a persons energy requirements.
    • Individuals who are on stronger anti-diabetics including insulin might also experience tiredness as a sign of low blood sugar levels.
    • Blood sugar testing is a great way to determine whether high or low glucose levels can be the reason behind fatigue.

    Causes Related To Blood Sugar

    High blood glucose makes your blood sludgy, slowing circulation so cells cant get the oxygen and nutrients they need. Margaret commented, I can tell if my sugars are high in the morning, because groggy doesnt begin to describe it. Drugged is how it feels.

    Low sugars levels also cause diabetes fatigue, because when blood sugar is low, there is not enough fuel for the cells to work well.

    In addition, high blood glucose can cause diabetes fatigue through inflammation. Blood vessels get inflamed by the sugar. When this happens, according to research, immune cells called monocytes come into the brain, causing fatigue.

    Food And Sugar Sensitivities

    If your body is sensitive to sugar, you may experience fatigue due to the fact that it reacts by producing low amounts of beta-endorphins and serotonin. Low levels of these chemicals lead to an experience of fatigue and lethargy.

    If you are consuming other foods that your body cannot digest, it will increase inflammation-causing cytokines that can also cause your body to inhibit the production of Orexin.

    The more you are consuming these foods, the more tired you will feel. The problem goes deeper than just the experience of feeling tired, as this is just a symptom of a more serious underlying issue. Poor digestion is something not to be taken lightly.

    If ignored over a long period of time, this post-meal inflammation can lead to other problems within the body such as auto-immune diseases, digestive disorders, and other conditions.
