Diabetes Related Vertigo: Causes And Treatment

Vertigo is an abnormal sensation of motion that can happen when a person is sitting still or when their movement through space is inaccurately sensed. Knowing where we are in space and how we are moving requires reliable information from five senses:

  • Our vision orients movement by taking cues from vertical objects and the horizon.
  • Our inner ear orients us to angular movements as we turn our head and to our acceleration as we move forward.
  • Touch orients us as our weight presses us against things .
  • Proprioception detects the position of our neck and limbs as we move.
  • Our hearing orients us to objects reflecting sound and to sound-emitting objects.
  • Any impairment of these senses can lead to an experience of vertigo, disequilibrium or dizziness. Medical issues, including diabetes and heart disease, can potentially disrupt the functioning of these senses through nerve damage or circulation impairment.

    Vertigo and Disequilibrium

    Spinning vertigo is when either the environment appears to be spinning or a person feels that they are spinning within the environment. Positional vertigo is a spinning sensation occurring after a person repositions their head. A spinning sensation is often caused by inner ear problems.

    Diabetes and Dizziness

    Dizziness describes feelings of being lightheaded or sensing that one will faint. Individuals with diabetes may experience dizziness for several reasons:

    When Should I Call The Doctor For Dizziness

    Dizziness is a common complaint and often has resolved by the time the patient arrives to see a health care professional. Usually there is no rush to seek care. However, while the complaint of dizziness is not often an emergency, seek care immediately if it is accompanied by any of the following:

    • Chest pain, shortness of breath, or palpitations. These symptoms should not be ignored, as they suggest the heart may be the source of the dizziness.
    • Dehydration. Often there may be an associated illness including fever, vomiting, or diarrhea.
    • People with diabetes may have dizziness due to low blood sugar or high blood sugar , and may need emergent care to stabilize their insulin and medication requirements.
    • Bleeding from any source.
    • Altered mental status or thinking. This may include symptoms such as confusion, change in vision, change in speech, facial droop, weakness of one side of the body, or headache. These may be signs of stroke, bleeding in the brain, or tumor.
    • FAST warning signs of a stroke:
    • Face — facial droop
    • Arm — arm or leg weakness
    • Speech — difficulty speaking or understanding speech
    • Time — time is of the essence. Call 911.
  • Vertigo may cause significant problems with vomiting and may be debilitating. Often, medical care is needed to control symptoms even though the underlying problem is not necessarily serious.

    Exercise Food And Alcohol

    For people with type 1 diabetes, maintaining the correct blood glucose level involves balancing how much insulin you inject, the amount of food you eat, and how much energy you burn during exercise.

    Hypoglycaemia may occur if you’ve taken your dose of insulin as usual, but your carbohydrate intake is lower than normal or has been used up more quickly. This may happen if you delay or miss a meal or snack, don’t eat enough carbohydrate, or exercise more than usual.

    People with diabetes who’ve drunk too much alcohol, or drank alcohol on an empty stomach, can also get hypoglycaemia.

    However, it’s not always possible to identify why a particular episode of hypoglycaemia has occurred, and sometimes it happens for no obvious reason.

    Is your level of frustration a 20 out of 10? Angry and anxious for no obvious reason? It could be hypoglycemia. The most common mood changes are being belligerent and argumentative, says Dr. Wyne. Or it could be more subtle in just refusing to discuss something or not agreeing to something that is normally acceptable to you, she says. If your partner tells you youre crankier than usual, take note. Personality changes like Bettys a major sign of hypoglycemia, agrees Zappe.

    You’re Clammy And Sweatyfor No Obvious Reason

    With hypoglycemia you may break out in a cold sweat even though youre not overheated, and you may get pale and feel clammy. This happens because low blood-sugar levels trigger the bodys fight or flight response and the release of adrenaline, a hormone. This adrenaline burst causes sweating along with other symptoms. People with type 1 diabetes commonly feel damp and sticky from hypoglycemia at intervals throughout a given week.

    Severe hypoglycemia can also cause these symptoms:

    • confusion
    • seizures
    • not responding or waking up

    Teach your child about the symptoms of low blood sugar and what to do. Even young kids who can’t describe their symptoms can learn to tell an adult when they don’t feel well. Help your child understand that they need treatment when they dont feel well. And explain how to find an adult who can help them.

    When To See A Health Care Provider

    3 Causes Of Dizziness or Vertigo Explained By Dr.Berg

    If your dizziness when standing up only happens occasionally, there likely isnt any reason to worry. The normal pull of blood away from your head and heart and subsequent dizziness when standing can be a part of your bodys natural response to gravity. As epinephrine is released and your blood vessels are regulated, the symptoms will go away.

    If your symptoms are recurrent, come with other concerning symptoms, or you have been losing consciousness, seek medical advice. If you suspect that an underlying condition is causing your dizziness when standing up, keep track of your symptoms and consult your health care provider.

    Sudden Drop In Blood Pressure

    The autonomic nervous system helps the body regulate the shift in blood pressure when we stand up. As we get older, this system may deteriorate, causing a temporary drop in blood pressure when we standknown as orthostatic hypotensionresulting in lightheadedness. This may be a long-term problem, but there are medications to treat it, such as midodrine and fludrocortisone , so this too warrants a trip to your doctor.

    Can Diabetes Cause A Seizure

    Seizures that happen as a direct result of diabetes, notably if very low sugar levels occur, are known as non-epileptic seizures. It is possible for people to have both diabetes and epilepsy, and this can present challenges in recognising whether the seizures are related to epilepsy or blood sugar levels.

    When To See A Doctor

    A single instance of dizziness after eating does not usually mean that a person has a serious medical condition. It may be that a personâs blood sugar or blood pressure temporarily shifted or that something in their meal triggered dizziness. There is no need to see a doctor for a brief spell of dizziness.

    Pregnant women who experience dizziness after a meal typically find that this symptom improves after delivery. However, if the dizziness is intense, prolonged, or interferes with the womanâs functioning, she should call a doctor.

    Rarely, very low blood pressure can cut off blood supply to the brain. When this occurs, it may cause an ischemic stroke, which can be life threatening. A person who has symptoms of a stroke should go to the emergency room or call 911 or the local emergency number.

    Some strategies may help reduce dizziness after eating. People can try the following:

    Heart Conditions Which Cause Dizziness

    Wellness Lab Health Info: 10/28/15

    The heart is an electrical pump and for it to work, the electrical conduction system must be operating properly to stimulate the heart muscle to squeeze in a coordinated fashion and pump blood to the body. The heart muscle itself must be strong enough to pump blood, and the valves in the heart must work properly to allow blood to flow in the direction intended during contraction.

    • Conduction disturbances: Electrical conduction disturbances may make the heart beat too quickly or too slowly , and either of these situations may result in an inadequate blood supply to the brain, causing dizziness or lightheadedness.
    • Cardiomyopathy: Dizziness is also a symptom of cardiomyopathy , a disease of the heart muscle, resulting in muscle that doesn’t squeeze effectively. Most commonly the weakness is due to atheroscleroticheart disease or ischemic cardiomyopathy , in which the heart muscle itself doesn’t get enough blood supply to work properly. Other non-ischemic cardiomyopathies may be due to diabetes, alcohol use, and viral infections.

    Treating An Episode Of Hypoglycaemia

    The immediate treatment for hypoglycaemia is to have some sugary food or drink to end the attack.

    For example, this could be:

    • a glass of fruit juice or non-diet soft drink
    • between three and five dextrose tablets
    • a handful of sweets

    At first you should avoid fatty foods and drinks, such as chocolate and milk, because they don’t usually contain as much sugar and the sugar they do contain may be absorbed more slowly.

    After having something sugary, you should have a longer-acting carbohydrate food, such as a few biscuits, a cereal bar, a piece of fruit or a sandwich.

    It will usually take around 15 minutes to recover from a mild episode of hypoglycaemia. If you have a blood glucose meter, measure your blood sugar again after 15 to 20 minutes. If it’s still too low , you should have some more sugary food or a drink before testing your levels again in another 15 to 20 minutes.

    When treating someone else with hypoglycaemia, if the above treatment isn’t effective, you may be able to help them by applying glucose gel to the inside of their cheeks, and gently massaging the outside of their cheeks.

    It may take 10 to 15 minutes before they feel better. This shouldn’t be done if the person is drowsy or unconscious because of the risk of choking.

    How Can I Prevent Low Blood Sugar In The Morning

    If you have diabetes, make sure you regularly check your glucose levels, especially before bed. If your blood sugar regularly dips while you sleep, consider using a continuous glucose monitoring device, which alerts you when your blood sugar goes too low or too high. Try to follow these guidelines for healthy glucose levels:

    • before breakfast: 70130 mg/dL
    • before lunch, dinner, or a snack: 70130 mg/dL
    • two hours after meals: under 180 mg/dL
    • bedtime: 90150 mg/dL

    If you dont have diabetes but experience regular hypoglycemia, you may also want to periodically check your glucose levels. Try to keep your glucose level from dropping below 100 mg/dL throughout the day and before bed.

    Whether or not you have diabetes, follow these tips to avoid waking up with low blood sugar:

    • Eat balanced meals with healthy carbohydrates, proteins, and fats regularly throughout the day.
    • Have a bedtime snack.
    • If you drink alcohol, avoid excessive intake and have a snack with it.
    • Avoid exercising too much at night.

    For a bedtime snack, try these suggestions:

    • 1 apple with 1 tablespoon of peanut butter
    • 1 ounce of cheese and a small handful of whole-grain crackers
    • one 8-ounce glass of milk
    • 1/2 avocado spread on a piece of whole-grain toast
    • handful of berries with a small handful of nuts and seeds

    Why Do I Suddenly Feel Dizzy

    Sudden dizziness can stem from many issues, including problems with the inner ear, low blood pressure, and mental health conditions. The dizziness may resolve on its own, but it is a good idea to seek medical advice. People who feel dizzy may describe it as feeling lightheaded, off-balance, giddy, or faint.

    Benign Paroxysmal Positional Vertigo


    Benign paroxysmal positional vertigo was found in 8% of individuals with moderate or severe dizziness or vertigo in a German study which showed a lifetime prevalence of BPPV of 2.4%, a one-year prevalence of 1.6% and a one-year incidence of 0.6%.

    Some studies suggest that people with diabetes are more at risk of BPPV than those without diabetes. Among people with type 2, 84% had abnormal test performance on assessment of at least one vestibular end organ. Among patients aged > 18 years with a vestibular diagnosis for symptoms of dizziness, BPPV was found in 46% of people with diabetes vs 37% in those without diabetes. However, logistic regression analysis showed that the presence of hypertension mediated the higher frequency of BPPV in diabetes.

    BPPV is treatable, so seek expert advice if you suspect this diagnosis.

    Is It Your Circulation

    Dizziness can be a sign of a problem with your blood flow. Your brain needs a steady supply of oxygen-rich blood. Otherwise, you can become lightheaded and even faint.

    Some causes of low blood flow to the brain include blood clots, clogged arteries, heart failure, and an irregular heartbeat. For many older people, standing suddenly can cause a sharp drop in blood pressure.

    It’s important to get medical help immediately if you’re dizzy and faint or lose consciousness.
