Your Collar’s Too Tight
Carotid sinus syncope, or “tight-collar syndrome,” happens when something pushes on nerves at a wide part of your carotid artery in your neck. This interferes with blood flow to the brain and makes you faint. It happens quickly and without other symptoms like nausea, paleness, and sweating. In some cases, if it hasn’t happened before, it may be a sign of narrowed arteries that need treatment.

Eat Smart To Prevent Lightheadedness
According to the National Institute of Diabetes and Digestive and Kidney Diseases , low blood sugar occurs when a person’s glucose levels drop below normal levels. That’s often considered to be 70 milligrams per deciliter or less.
If you have diabetes and are experiencing dizziness, the cause could be your insulin shot or other diabetes medications. For some, it has to do with the specific food you eat or the time you eat it. Skipping or delaying a meal can cause blood sugar levels to plummet, according to the NIDDK. Drinking too much alcohol without food in your stomach can also cause this. In each case, though, the solution is simple.
“Eat or drink something,” says Lona Sandon, PhD, RDN, program director and associate professor in the Department of Clinical Nutrition at University of Texas Southwestern Medical Center at Dallas. “If your lightheadedness is truly caused by hypoglycemia because you have not eaten in several hours, the answer is simple: Eat something.”
In a pinch, “hypoglycemia is most quickly corrected with about 15 grams of carbohydrate,” Sandon says. A half-cup of juice is one example, she adds.
Of course, if dizziness attributed to a sugar low is driven by alcohol, make sure to take in some food before you reach for that next alcoholic drink, suggests the NIDDK. That’s important because if you’ve been drinking, your body has a harder time keeping your blood sugar steady, especially on an empty stomach, it says.
Can Having Gestational Diabetes Make You Tired
Gestational diabetes is a condition that approximately 4% of women experience during pregnancy. Due to the hormones, insulin resistance occurs, and causes higher blood sugar levels. This can be a problem because it causes babies to be born larger and have difficult births. It can also cause birth defects and it makes the first few days difficult for the newborn to maintain their blood sugar. It usually can be controlled with a change in diet, but sometimes insulin may be required.
Some women show no signs of gestational diabetes, while other have extreme fatigue, elevated thirst, and an increase in urinating. The problem is that most pregnant women experience all of these symptoms anyway. For this reason, all women are tested for gestational around 24 weeks of pregnancy. Women at a higher risk may be tested earlier.
If fatigue does become worse during pregnancy, the expectant mother should seek help from their physician to rule out gestational diabetes or other complications such as low blood pressure or anemia .

Nighttime Low Blood Sugar
While low blood sugar can happen at any time during the day, some people may experience low blood sugar while they sleep. Reasons this may happen include:
- Having an active day.
- Being physically active close to bedtime.
- Taking too much insulin.
- Drinking alcohol at night.
Eating regular meals and not skipping them can help you avoid nighttime low blood sugar. Eating when you drink alcohol can also help. If you think youre at risk for low blood sugar overnight, have a snack before bed.
You may wake up when you have low blood sugar, but you shouldnt rely on that. A continuous glucose monitor can alert you with an alarm if your blood sugar gets low while youre sleeping.
Low Blood Glucose During Sleep
Your blood glucose level can drop while you sleep and stay low for several hours, causing serious problems.7 Symptoms of low blood glucose while you sleep can include

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

How Do You Treat Hypoglycemia
Low blood sugar levels happen when theres too little glucose left in the bloodstream to continue supplying fuel to your organs, muscles, and tissues. It most often occurs when you dont eat enough food, especially carb-containing foods, given your blood-sugar-lowering medications and physical activity levels, ONeill says. Levels can decrease gradually or suddenly.
When the amount of glucose in the bloodstream drops to too-low levels, the body reacts by releasing epinephrine, also called adrenaline or the fight or flight hormone. Epinephrine revs your heart rate and can cause sweating, shaking, anxiety, and irritability. If not enough glucose is able to reach the brain, the result may be difficulty concentrating, confused thinking, and slurred speech. In extreme cases, a lack of glucose within the brain can lead to seizures, coma, and even death, she says.
People with low glucose levels can use the ADAs 15-15 Rule, which advises people consume 15 g of carbs, wait 15 minutes, and check their levels again. If the number is still low, repeat until reaching at least 70 mg/dL.
You can find 15 g of carbs in:
- 1 slice of bread
- 1 small piece of fresh fruit
- cup of yogurt
- Three to four hard candies
- Glucose tablets as indicated on the label
- Glucose gel as indicated on the label
Once your glucose levels are back to normal, the ADA suggests going ahead and eating your next scheduled meal or snack, which will help prevent levels from dropping again.
How Is Vertigo Diagnosed
The diagnosis of vertigo is most often made based upon history and clinical presentation. If the patient is experiencing a spinning sensation that worsens by a change in position, and lessens by lying still, the health care professional can confirm the cause of dizziness as vertigo if there are appropriate findings on physical examination.
The doctor may take a further history to make certain that the symptom of vertigo is isolated to an inner ear condition and not due to a problem in the brain .
Physical examination will focus on the neurologic examination and may involve looking at eye movements. With vertigo, nystagmus may be present. Nystagmus is an involuntary movement of the eyes, slow and smooth in one direction with fast twitches in the other. It is the eyes’ attempt to compensate for the abnormal signals created in the inner ear. The patient may be asked to lay flat or sit upright to uncover the presence of nystagmus.
The doctor may test the patient’s hearing to assess potential hearing loss. This may be seen in Meniere’s disease or with an acoustic neuroma, but not necessarily with labyrinthitis or benign positional vertigo.
The rest of the neurologic examination may be done to look for one-sided weakness, loss of coordination, or loss of balance as potential signs of stroke.

How Long Will The Effects Last
The effects of low blood sugar will continue and may even get worse until treatment brings your blood sugar level back to normal. It may take several minutes for the symptoms to go away after you start treatment. This may be a temporary problem while you and your healthcare provider are adjusting your medicine. If you are always prone to having low blood sugar, you may need to take special care for the rest of your life to keep your blood sugar at the proper level.
What Causes Low Blood Glucose In People With Diabetes
Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.
Two types of diabetes pills can cause low blood glucose
- sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
- meglitinides, taken before meals to promote a short-term increase in insulin
The following may also lower your blood glucose level

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.

Theyre much less than 100 mg/dL after not consuming for at the very least 8 hours. And theyre less compared to 140 mg/dL 2 hrs after consuming.
Throughout the day, degrees have the tendency to be at their lowest right before dishes. For many people without diabetic issues, blood sugar level levels before meals hover around 70 to 80 mg/dL. For some individuals, 60 is regular for others, 90.
Whats a reduced sugar degree? It differs extensively, too. Several peoples sugar will not ever fall listed below 60, despite prolonged fasting. When you diet plan or fast, the liver maintains your degrees regular by turning fat and muscle mass right into sugar. A few individualss levels may fall rather lower.Symptoms Of High Blood Sugar Dizziness

Ask Your Doctor How Often You Should Be Checking Your Blood Sugar
Blood sugar control is crucial when youre living with type 2 diabetes. Dips and spikes can not only make you feel cranky and sluggish, but they can also wreak havoc on your personal health.
For the record, the American Diabetes Association notes that you have diabetes if one of the following applies to you:
- Your blood glucose after fasting is 126 milligrams per deciliter or higher.
- Your blood glucose two hours after eating a meal is 200 mg/dl or higher.
- Your hemoglobin A1C is 6.5 or higher.
The tricky part is that with type 2 diabetes you may not feel it when blood sugar levels are too high, according to the ADA. It feels different for everyone. Not everyone will have the same symptoms, and some individuals will have no symptoms at all, says Lori Zanini, RD, CDE, a Los Angelesbased former spokesperson for the Academy of Nutrition and Dietetics.
Because blood sugar management is so important to your overall health with type 2 diabetes, you need to take action if you think your levels may be out of control, even if youre feeling totally fine.
