Does Everyone Have Symptoms From Hypoglycemia

Low blood sugar – Causes, symptoms and solution – HYPOGLYCEMIA

Some people dont have symptoms or dont notice them. Healthcare providers call that situation hypoglycemia unawareness. People with such a challenge arent aware when they need to do something about their blood sugar. Theyre then more likely to have severe episodes and need medical help. People with hypoglycemia unawareness should check their blood sugar more often.

Diabetic Fainting: Two Types Of Syncope

Fainting, also called syncope, results from a temporary insufficiency in the supply of blood to the brain. Syncope can be the result of many disorders, some benign and some more serious. Some of the complications of diabetes can lead to episodes of syncope.

Two Types of Syncope

There are two primary body systems that are responsible for fainting. The first is the autonomic nervous system – the brain, nerves and spinal cord. These are the areas of the body that automatically regulate such functions as heartbeat, breathing and blood pressure. The second is the cardiovascular system.

Autonomic Nervous System Syncope

This type of syncope is also known as neurally mediated syncope, and it is the most common cause for fainting. It results from a failure of the autonomic nervous system to maintain blood pressure at an appropriate level. This may be due to a momentary slowing or pause of the heart or, conversely, an abnormal speeding of the heart rate upon standing .

The triggers can also be as simple as seeing something unpleasant , sudden heat or sudden pain.

Coughing or sneezing, or even laughing can also cause a fainting spell. This is called situational syncope.

Blood sugar levels also have an impact. If blood glucose is not well controlled, it can damage nerve fibers. This damage can happen to the nerves that control blood pressure, resulting in ineffective control of blood pressure, increasing the incidence of fainting.

The Science Behind A Blackout

A blackout occurs when alcohol causes a disruption in the link between your long-term and short-term memory. Medically speaking, there can be a partial disruption between the two types of memory, and this is referred to as a brownout. During a partial disruption, you may remember events by a verbal or visual clue, as opposed to a total blackout where you have no idea what happened. During a blackout, the memory loss is permanent.

Warning Signs Of Low Blood Sugar

Hypoglycemia can cause both short- and long-term complications. Know the signs so that you can treat the condition as soon as you’re aware of it.

As a person living with diabetes, you know how important it is to reduce blood sugar when it is too high, a phenomenon called hyperglycemia. But blood sugar that is too low, or hypoglycemia, is equally critical to avoid.

Hypoglycemia happens when the amount of blood glucose drops to a level that’s too low to sustain normal functioning,” says Erin Palinski-Wade, RD, CDCES, who is based in Sparta, New Jersey. “In most people, this is defined as a blood sugar level at or below 70 milligrams per deciliter .”

Hypoglycemia is common among people with type 2 diabetes, according to a review published in June 2015 in the journal PLoS One. Individuals with the condition had an average of 19 mild or moderate episodes of hypoglycemia per year and nearly one severe episode per year on average, according to the researchers. Low blood sugar was particularly common among those taking insulin.

This decrease in blood sugar levels can cause both short-term complications, like confusion and dizziness, as well as more serious issues, including seizures, coma, and, rarely, death, according to the American Diabetes Association .

Hypoglycemia is usually the result of a too-high dose of insulin or a change in diet or exercise habits, according to Harvard Health Publishing.

It’s dangerous. If you’re driving and you have hypoglycemia symptoms, pull off the road, check your blood sugar, and eat a sugary food. Wait at least 15 minutes, check your blood sugar, and repeat these steps if needed. Eat a protein and carbohydrate source before you drive on. Be prepared. Keep a sugar source, such as glucose tablets, in your car at all times for emergencies.

How Can I Stop My Blood Sugar From Crashing

Here are a few ways to avoid hypoglycemic episodes:

  • Get in the habit of self-monitoring your blood glucose. Keeping track of when your blood sugar drops can help you recognize aspects of your routine that may be contributing to your hypoglycemia. Dr. Klonoff recommends a continuous glucose monitor. Its the best tool for automatically checking your blood glucose levels around the clock, he says.
  • Change your meal plan. When, what, how much, and how often you eat all play a big part in your blood glucose levels. A dietitian can teach you about healthy, well-balanced food choices that will make it easier for you to maintain an acceptable blood sugar range.
  • Keep a stash of glucose tablets on hand. With your doctor’s recommendation, make sure you always have glucose tablets with you. You can stick them in your briefcase, purse, car, desk, school locker, etc. You may also want to keep snacks nearbyfor example, cheese or peanut butter crackers, although doctors suggest over-the-counter glucose tablets for more accurate dosage. Do not eat a healthy sugar-free candy bar during hypoglycemia, warns Dr. Klonoff. Its lack of sugar means that it will not raise your blood glucose level sufficiently when you want it to.
  • Certain drinks can help get your blood sugar up as well. Try 8 oz. of fruit juice, a soft drink , or a cup of milk.

Replies On Blacked Out From Hypoglycemia

Intermittent Fasting & Hypoglycaemia: Fasting With Low Blood Sugar? | Dr. Nick Z.

hypoglycemia is low blood sugar below 70 mg/dL or 3.89 mmol/Lhyperglycemia is diabetes high blood sugar above 126 mg/dL or 7.00 mmol/L

hypo will cause dizzy blackout coma because not enough sugar going to the brain. i dont think you have hypo if heredity is suspected. because your grandpa is hyper

i had a blackout missed the subway station often, the brain scan shown a dark spot at the back of the brain , the neurologist didnt pursue farther.

you should see a neurologist for the blackout.

a portable meter measure the sugar in the plasma. in the lab blood test they measure sugar in plasma A1C sugar in red blood cells hemoglobin average reading for the past 6 wks. .

you should have a blood test done by the lab

sugar in plasma is not reliable, it is up and down depends on the time of day , could lead to wrong diagnostic. so most doctors rely on A1C results to prescribe medication

A1C = 3.63 for hypo and A1C = 5.70 for hyper

the relationship of A1C and plasma glucose in the internet is not uniform, the most reliable is using the following experimental formula%A1C = / 35.6 or%A1C = / 1.98

Alcohol And Blood Sugar

However, its not only the high sugar content of alcohol that can affect your body drinking to excess has also been shown to have a negative effective on blood sugar.

When a person drinks alcohol, the body reacts to it as a toxin, and channels all energy into expelling it.

This means that other processes are interrupted including the production of glucose and the hormones needed to regulate it. This is most noticeable is in heavy drinkers, as over time drinking too much alcohol decreases the effectiveness of insulin, which leads to high blood sugar levels.

Alcohol also affects blood sugar levels each time its consumed, which means occasional drinkers can also be negatively impacted. Alcohol consumption causes an increase in insulin secretion, which leads to low blood sugar . This causes light headedness and fatigue, and is also responsible for a host of longer-term alcohol-related health problems.

What Can You Do If You Feel Like You’re Going To Faint

  • Lie down flat with your legs up on a chair or against a wall or sit down on the ground with your head between your knees. Do not just sit on a chair.
  • Squatting down on your heels can be very effective and is less noticeable in public.
  • When feeling better, get up carefully. If symptoms return, resume the position.

If you faint again:

  • Discuss with your doctor stopping any medication that may be responsible.
  • Avoid alcohol.
  • Drink more fluids such as water or soft drinks.
  • Wear support stockings.
  • Do leg crossing and arm tensing exercises.

What If Im Experiencing Hypoglycemic Episodes Even Though My Doctor Has Confirmed That Im Not Diabetic Or Prediabetic

Low Blood Sugar Can Be Deadly. Here

If you have low blood sugar and dont have diabetes or prediabetes, it can be a sign of another serious health issue such as a tumor, hormone deficiency, kidney disorder, anorexia, or other eating disorder, all of which can cause dangerously low blood sugar.

Anorexia has the highest mortality of any psychiatric disorder, and the cause of death can be hypoglycemia, so take your illness seriously and seek help if you suspect your eating disorder may be progressing to the point where it is causing you to faint or experience other signs and symptoms of dangerously low blood sugar. The National Eating Disorders Association has resources on how to identify the signs that you may have an eating disorder, a hotline for help, as well as easily accessible information on everything from how to know when you need help to how to find quality treatment options in your zip code.

People who are not diabetic don’t spontaneously have hypoglycemia for no reason, explains Dr. Christofides. Its often an indication of another underlying issue, such as a hormone deficiency or eating disorder, so its important to schedule an appointment with your doctor to determine the cause in order to prevent complications.

Common causes of hypoglycemia in people without diabetes include:

  • Pancreatic tumor
  • Medication that inhibits the proper production of insulin
  • Hepatitis or kidney disorders
  • Hormone deficiencies
  • Anorexia and other eating disorders

  • If the fainting episode is resolves quickly, and the person returns to normal function with no evidence of injury, it may be appropriate to contact a primary care doctor to discuss care options.
  • Often, if the fainting episode does not go away quickly, the person will be placed on a heart monitor, have intravenous line fluids, and oxygen supplied. A fingerstick blood sugar may be checked to test for low blood .
  • Treatment for the cause of fainting will be tailored to each person.
