What other conditions can mimic stroke symptoms?
What other conditions can mimic stroke symptoms? Conditions and diseases that can resemble symptoms of strokes include: Brain tumors, specifically glioma, meningioma and adenoma/pituitary. Toxic or metabolic disorders, including hypoglycemia, hypercalcemia and hyponatremia.
What is considered a dangerously low blood sugar level?
Very low blood sugars are any readings under 40 mg/dL. Anything under 40 mg/dL is considered extremely dangerous and potentially fatal. A person is at a significantly higher risk of falling into a diabetic coma if they cannot get their blood sugar above 40 mg/dL for several hours.
What condition most closely mimics hypoglycemia?
Migraine Headache.Multiple Sclerosis.Myeloproliferative Disorders.Preeclampsia.Roundworms.Stroke.Transient Ischemic Attacks.Varicella-Zoster Virus.More items...
What symptoms would confirm a suspicion of hypoglycemia instead of drugs?
An initial blood glucose reading may confirm suspicion of hypoglycemia. If you suspect that your patient is hypoglycemic, obtain a blood glucose level through skin puncture....HypoglycemiaCold, clammy skin.Weakness, faintness, tremors.Headache, irritability, dullness.Hunger, nausea.Tachycardia, palpitations.
Why do I feel hypoglycemic with normal blood sugar?
A: Some people with diabetes can't comfortably tolerate a glucose level that is at the lower end of the ideal target range. Their bodies react to near-normal blood sugars with an early release of the hormone norepinephrine. And they can have symptoms that are similar to symptoms of hypoglycemia.
What are the three classic signs of hypoglycemia?
Initial signs and symptoms of diabetic hypoglycemia include: Looking pale (pallor) Shakiness. Dizziness or lightheadedness.
Can you have low blood sugar and not diabetes?
Non-diabetic hypoglycemia, a rare condition, is low blood glucose in people who do not have diabetes. Clinicians usually want to confirm non-diabetic hypoglycemia by verifying classic symptoms along with a low sugar level AND that these symptoms recover after eating sugar.
What is false hypoglycemia?
False hypoglycemia is having the symptoms of hypoglycemia when your blood glucose levels are in normal range or even above normal range. False hypoglycemia may occur in: • People with newly diagnosed diabetes whose blood glucose was significantly. above normal, and is now lower.
Can you have hypoglycemia without low blood sugar?
People with IPS have the symptoms of hypoglycemia 2 to 4 hours after a meal, but they don't have low blood glucose. This usually occurs after eating a high-carbohydrate meal. Other names for IPS include: carbohydrate intolerance.
What triggers reactive hypoglycemia?
Causes of Reactive Hypoglycemia This added insulin makes your blood glucose level drop below normal. Reactive hypoglycemia can also result from tumors, alcohol, surgeries -- like gastric bypass or ulcer treatment -- and possibly some metabolic diseases. It's more common if you're overweight.
How do you diagnose hypoglycemia?
The only way to know if you have hypoglycemia is to check your blood sugar with a blood glucose meter. It's a small machine that measures blood sugar. Most of these devices use a tiny prick of the finger to take a small amount of blood. People with hypoglycemia unawareness may need a continuous glucose monitor.
What could a differential diagnosis for the signs and symptoms of hypoglycemia be?
Differential DiagnosesAddison Disease.Adrenal Crisis.Alcoholism.Anxiety Disorders.Cardiogenic Shock.Hypopituitarism (Panhypopituitarism)Insulinoma.Pseudohypoglycemia.
What are the symptoms of hyperglycemia?
Signs and symptoms include:Fruity-smelling breath.Nausea and vomiting.Shortness of breath.Dry mouth.Weakness.Confusion.Coma.Abdominal pain.
How do they test for hypoglycemia in non diabetics?
Your doctor can diagnose non-diabetic hypoglycemia by reviewing your symptoms, doing a physical exam, looking at your risk for diabetes, and checking your blood glucose level. Your doctor will also see whether you feel better after you eat or drink to raise your glucose to a normal level.
What is acute symptomatic hypoglycaemia?
Abstract Background Acute symptomatic hypoglycaemia is a differential diagnosis in patients presenting with stroke-like neurological impairment, but few textbooks describe the full brain imaging appearances. We systematically reviewed the literature to identify how often hypoglycaemia may mimic ischaemic stroke on imaging, common patterns and relationships with hypoglycaemia severity, duration, clinical outcome and add two new cases. We searched EMBASE and Medline databases for papers reporting imaging in adults with symptomatic hypoglycaemia. We analysed the clinical presentation, outcome, brain imaging findings, duration and severity of hypoglycaemia, time course of lesion appearance, including two new cases. We found 42 papers describing computed tomography or magnetic resonance imaging in 65 patients, plus our two cases with symptomatic hypoglycaemia. Imaging abnormalities on computed tomography and magnetic resonance were uni or bilateral, cortical or sub-cortical. Thirteen (20%) mimicked cortical or lacunar stroke. Acute lesions had restricted diffusion on magnetic resonance or low attenuation on computed tomography, plus swelling; older lesions showed focal atrophy or disappeared, as with ischaemic stroke. The association between the depth or duration of hypoglycaemia, the severity or extent of neurological deficit, and the imaging abnormalities, was weak. Imaging abnormalities in patients with hypoglycaemia are uncommon but very variable, weakly associated with neurological deficit, and about a fifth mimic acute ischaemic stroke. Blood glucose testing should be routine in all patients with acute neurological impairment and hypoglycaemia should be included in the differential diagnosis of imaging appearances in patients presenting with acute stroke.

What are the objectives of hypoglycemia?
Hypoglycemia Objectives The objectives of this module will be to Review the signs and symptoms associated with hypoglycemia. Review the methods of treating a patient with hypoglycemia. Review the disposition of a patient presenting to the emergency department with hypoglycemia. Hypoglycemia is an important and easily reversible cause of altered mental status in patients presenting to the emergency department. Hypoglycemia accounts for approximately 7% of patients presenting to the emergency department with an altered mental status. In diabetic patients, approximately 25% will experience hypoglycemia on a regular basis. There is no universally accepted definition, but this condition is generally defined as a blood glucose level < 50-60 mg/dL. Symptoms will vary significantly between patients and the blood glucose level at which a patient become symptomatic is also highly variable. Initial Actions and Primary Survey Hypoglycemia should be considered in the differential diagnosis of all patients with an altered mental status (including the pre-hospital setting). Nowadays, this condition is rapidly identified with bedside glucometers and rapidly treated with intravenous dextrose. A patient presenting with hypoglycemia can easily be misdiagnosed as a stroke, seizure, psychosis, drug ingestion, or a traumatic head injury if the blood glucose level is not obtained. Failure to determine blood glucose levels early in the evaluation process can lead to a missed diagnosis and be associated with progressive CNS dysfunction, cardiac dysrhythmias, or even death. Obtaining an accurate medical history in a patient with an altered mental status can be difficult. Attempts should be made to elicit any history of diabetes, renal or liver failure, alcohol or drug use and to determine an acc Continue reading >>
What is the difference between hypoglycemia and ischemic stroke?
Answer: First a few Definitions: Hypoglycemia = Low blood sugar. Ischemic stroke = Artery blockage leading to decreased blood flow to the brain. Stroke vs hypoglycemia: This is a really good question and one that ER doctors struggle with all the time. Both conditions can present with similar/same symptoms. In addition, they are both medical emergencies and treated very differently. The easiest way to start to figure out what is going on is to check your blood sugar. This is what is done at the ER and you can do it yourself too. But you should first call 911. Why are there same/similar symptoms?: Since the brain uses glucose as energy and does not store any, low glucose levels quickly lead to impaired brain function. On the other hand, an ischemic stroke is caused by a blocked artery that supplies nutrients to the brain. Blocked flow quickly leads to impaired brain function. Depending on the individual patient and the degree of the problem, someone may have one or many different symptoms. Some common symptoms of stroke: Sudden numbness/ or weakness; face, arm or leg, especially on one side of the body Sudden confusion, trouble speaking or understanding Sudden trouble seeing in one or both eyes Sudden trouble walking, dizziness, loss of balance or coordination Sudden, severe headache with no known cause Seizures Loss of consciousness Confusion, abnormal behavior or both Some common symptoms of hypoglycemia: Nervousness Sweating Intense hunger Trembling Weakness Palpations Trouble speaking Numbness Confusion, abnormal behavior or both Inability to complete routine tasks Visual disturbances, such as double vision and blurred vision Seizures Loss of consciousness If you think you are having a stroke, go to the ER: Time is brain; the longer an artery is blocked, the more the Continue reading >>
Why does a low glucose level cause a stroke?
On the other hand, an ischemic stroke is caused by a blocked artery that supplies nutrients to the brain. Blocked flow quickly leads to impaired brain function.
Does hyperglycemia worsen stroke?
Practice Essentials Preexisting hyperglycemia worsens the clinical outcome of acute stroke. Nondiabetic ischemic stroke patients with hyperglycemia have a 3-fold higher 30-day mortality rate than do patients without hyperglycemia. In diabetic patients with ischemic stroke, the 30-day mortality rate is 2-fold higher. [1] With regard to hypoglycemia, the condition can mimic acute stroke or symptoms of transient ischemic attack (TIA). [2, 3, 4, 5] Signs and symptoms Hyperglycemia in stroke Patients may come to the attention of clinicians because of preexisting diabetes mellitus Diabetes may also be seen with other risk factors for stroke, such as hypertension and hypercholesterolemia High glycemic levels may also be seen in the setting of an acute stroke without a history of diabetes, presumably due to a sympathetic response to the infarct Retinopathy, neuropathy, and peripheral vascular disease may be found in patients with long-standing diabetes Hypoglycemia in strokelike occurrences In the literature, signs of an acute stroke, such as hemiplegia, aphasia, and cortical blindness, have been reported with hypoglycemia. In individuals presenting with low glycemic levels and strokelike symptoms, diabetes mellitus may have been previously diagnosed, and recent changes in the doses of hypoglycemic agents and insulin may have been instituted. In particular, aggressively tight glucose control, either patient driven or clinician directed, may give rise to chronic or recurrent episodes of hypoglycemia. However, if factitious hypoglycemia is suspected, such behavior may have manifested earlier as similar episodes or other factitious behaviors. Symptoms caused by hypoglycemia can occur suddenly and fluctuate, suggesting a vascular etiology. Diagnosis Laboratory studies In the settin Continue reading >>
Is It A Migraine, Low Blood Sugar, A Seizure…or A Stroke?
The symptoms are similar to a stroke—slurred speech, a weakness on one side of your body and confusion—but what you’re experiencing is actually low blood sugar, a migra ine or another condition. If you know you have diabetes, suffer from migraines, have a seizure disorder or other conditions, you may be tempted to ignore possible stroke symptoms. That’s a big mistake. Reason: When you’re having a stroke, minutes—even seconds—count. Getting emergency treatment with blood clot–dissolving medications—typically tissue plasminogen activator (tPA)—or other therapies can mean the difference between life and death and can dramatically affect recovery. To learn more about stroke mimics, we spoke with Edward Jauch, MD, director of the division of emergency medicine at the Medical University of South Carolina. MIMIC #1: LOW BLOOD SUGAR (HYPOGLYCEMIA) When blood sugar dips too low, a common problem for people who take medication for diabetes, the symptoms mimic a stroke—confusion, feeling dizzy or light-headed, slurred speech and/or muscle weakness. Clues that it may be hypoglycemia, not stroke: Symptoms may build up slowly, rather than occur suddenly, as they do with a stroke. If you do a finger prick and discover your blood sugar is low, and if symptoms resolve after eating a glucose tablet or drinking a half cup of fruit juice, it’s likely not a stroke. But if you have any doubts, call 911. Be sure to tell the EMS professionals that the patient is a diabetic so they can rule out hypoglycemia with a finger-prick test—and maybe save a trip to the ER. It’s actually standard practice to test everyone’s glucose right away, whether or not they have diabetes, but it’s not always followed, says Dr. Jauch. MIMIC #2: HEMIPLEGI Continue reading >>
What is hypoglycemic episode?
When to See a Doctor. Hypoglycemia is a potentially dangerous medical condition that occurs when your blood glucose (sugar) levels are too low. A blood glucose level of less than 70 mg/dl is considered low, or hypoglycemic.
Why do people with diabetes have hypoglycemia?
People with diabetes remain at risk for episodes of hypoglycemia throughout life because they need medications that lower blood sugar. The one exception is individuals with type 2 diabetes who manage their condition with lifestyle changes or blood sugar normalizing medications—such as metformin —alone. This group tends to have higher blood sugar levels ( hyperglycemia ).
How Long Does a Hypoglycemic Episode Last?
The duration of hypoglycemic episodes varies depending on the cause of the event.
What to do if you have diabetes and you are lethargic?
If you know someone with diabetes who suffers from hypoglycemia, call for emergency medical assistance if they become acutely lethargic, obviously disoriented, or unconscious. Severe insulin reactions can be fatal, so it is important to seek treatment immediately.
Why is it important to know your blood sugar?
Recognizing low blood sugar is important because it can help you to take immediate steps toward preventing a medical emergency. 2.
What is the normal blood sugar level for an adult?
A normal blood sugar level for an adult is between 70 and 130 mg/dL before a meal and less than 100 mg/dL when fasting. After a meal, a normal blood sugar level rises to below 180 mg/dL. To avoid hypoglycemia, one’s blood sugar must be above 70 mg/dL, but not above 180 mg/dL at any point as this may lead to hyperglycemia.
Can hypoglycemia affect blood sugar?
A Word From Verywell. Hypoglycemia can have an insidious impact on your health, so monitoring your blood sugar even when you are not feeling symptoms is the key to preserving your health. If you are experiencing symptoms of a hypoglycemic attack, seek immediate medical attention.
What are the symptoms of hypoglycemia?
Some symptoms of hypoglycemia may include: dizziness. a feeling of extreme hunger. a headache. confusion. an inability to concentrate. sweating. shaking.
How to know if you have hypoglycemia?
Everyone reacts differently to fluctuations in their blood glucose levels. Some symptoms of hypoglycemia may include: 1 dizziness 2 a feeling of extreme hunger 3 a headache 4 confusion 5 an inability to concentrate 6 sweating 7 shaking 8 blurred vision 9 personality changes
How long does a fasting test for hypoglycemia last?
Your doctor may ask you to take a fasting test. This test can last as long as 72 hours. During the test, you’ll have your blood drawn at different times to measure your blood glucose level.
What is it called when you have too much sugar in your blood?
Hypoglycemia. Hypoglycemia is a condition that occurs when the sugar levels in your blood are too low. Many people think of hypoglycemia as something that only occurs in people with diabetes. However, it can also occur in people who don’t have diabetes. Hypoglycemia is different from hyperglycemia, which occurs when you have too much sugar in your ...
What happens if you don't have enough sugar?
If you don’t have diabetes, hypoglycemia can happen when you don’t have enough sugar in your blood or if your body can’t stabilize your blood sugar level. This occurs when your level drops below 70 milligrams per deciliter (mg/dL).
What happens if you have reactive hypoglycemia?
An overproduction of insulin causes reactive hypoglycemia. Having reactive hypoglycemia may mean you’re at risk of developing diabetes.
How to get more glucose in blood?
Drinking fruit juice is an easy way to get extra glucose into your bloodstream. These sources of glucose often briefly correct hypoglycemia, but then another drop in blood sugar often follows.
What causes hypoglycemia in diabetics?
Hypoglycemia is also caused by liver disease, a pancreatic tumor that releases too much insulin and drinking alcohol. Some people without diabetes have idiopathic hypoglycemia, which does not have a known cause. Blood glucose levels that fall below 70 mg/dL indicate hypoglycemia.
What is hypoglycemic stroke?
What Is a Hypoglycemic Stroke? Hypoglycemia, which is a complication of diabetes, is the medical term for dangerously low blood glucose. A stroke occurs when the blood supply to the brain is interrupted by a blocked or burst vessel in the brain. Strokes kill brain cells and cause permanent brain damage.
Why is my blood glucose below 70?
The condition is caused by certain medications prescribed to treat diabetes, failure to eat enough food or take medications as prescribed, and exercising vigorously without eating enough food. Hypoglycemia is also caused by liver disease, a pancreatic tumor that releases too much insulin and drinking alcohol. Some people without diabetes have idiopathic hypoglycemia, which does not have a known cause.
What happens when glucose levels fall below 18?
When glucose levels fall below 18 mg/dL, a failure of brain energy can occur, which is confirmed with an electroencephalogram, or EEG, test to measure electrical activity in the brain. The death of brain neurons occurs, along with other permanent brain damage, when the brain’s electrical activity stops.
Can diabetes mimic a stroke?
While people with diabetes are at increased risk of having an actual stroke, the symptoms of hypoglycemia can also mimic those of a stroke. The term “hypoglycemic stroke” refers to the strokelike symptoms and brain damage resulting from severe hypoglycemia 3 .**.
Is hypoglycemia the same as ischemic stroke?
While hypoglycemic brain damage resembles that caused by ischemic stroke, there are differences, such as the lack of damage to the cerebellum and brainstem 3. According to research performed by Ronald N. Auer in 1986 and republished in the December 2004 issue of "Forensic Science International," hypoglycemia, like a stroke, is considered an attack or “insult” to the brain that kills brain cells 4.
What are the symptoms of hypoglycemia?
Symptoms of hypoglycemia include fatigue, headache, mood changes, heart palpitations and excessive sweating. Advertisement.
How to bring blood sugar up?
If you experience symptoms of hypoglycemia, you can bring your blood sugar back up by eating 15 to 20 grams of simple carbohydrates, according to the American Diabetes Association. Examples include 2 tablespoons of raisins, 8 ounces of nonfat milk, 4 ounces of juice or 1 tablespoon of honey. If you have diabetes, you can check your blood sugar using a blood glucose meter to find out whether it's back within the goal range your doctor set for you.
Why is it important to keep blood sugar levels within a narrow range?
Because glucose is a crucial fuel source for your organs and cells, your body works hard to keep its blood glucose level within a narrow range. When blood sugar falls below this normal range, it's called hypoglycemia. A number of circumstances can cause hypoglycemia, such as not eating for long periods of time, strenuous exercise, certain medications, poor diet and inherent abnormalities in glucose regulation. Symptoms of hypoglycemia include fatigue, headache, mood changes, heart palpitations and excessive sweating.
Can you have hypoglycemia without diabetes?
This refers to lower than normal blood sugar levels. However, you can experience hypoglycemia without having diabetes, in which case it's called nondiabetic hypoglycemia.
Does caffeine cause hypoglycemia?
Hypoglycemia is a common side effect of caffeine, according to Drugs.com. However, the mechanism responsible is poorly understood. Researchers found that caffeine impairs glucose sensitivity in a dose-dependent manner, starting at a very low dose, according to a study found in the February 2013 issue of "Applied Physiology, Nutrition and Metabolism." In the study, caffeine caused impaired glucose metabolism in healthy men and women. This data suggests that those with diabetes are not the only ones at risk for this side effect.
