Low Blood Pressure As A Cause Of Dizziness
Dizziness, lightheadedness, and the feeling of passing out is a common complaint in people who have low blood pressure. When the blood pressure is too low, not enough oxygen-rich blood is delivered to the brain, and its function can be affected. If the brain’s blood supply is decreased too much, the person may pass out . Symptoms may worsen when changing position from lying down or sitting to standing up.
In addition to feeling dizzy, associated symptoms may include:
In individuals who are dehydrated or anemic, blood pressure readings may be normal when they are lying flat however, the lack of fluid is unmasked when they stand up quickly. The lack of blood to the brain may cause dizziness and lightheadedness. This feeling may pass in a few seconds as the body adapts. However, if dehydration or medications prevent the body from reacting by constricting blood vessels and increasing the heart rate, the dizziness may persist to the point at which the patient passes out .
Some diseases are associated with an inability to compensate for changes in body position . Normally when a person stands, blood vessels contract to increase blood pressure slightly, and the heart rate also increases slightly, to pump blood uphill to the brain against gravity. In autonomic dysfunction, a person may become dizzy when they move from a lying position to sitting or standing up. Examples of these diseases with this syndrome include diabetes, Addison’s disease, or Parkinson’s disease.
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.
What Are The Treatments For Hypoglycemia
Make an appointment with an endocrinologist if you feel like youre having episodes of hypoglycemia, even if youre not diabetic. Theyll talk you through treatment strategies, including:
- Adjusting your medications. You may need to change how often you take insulin or other medications, which medications youre on, how much you take, and when you take them.
- Working with a registered dietitian on a personalized meal plan that stabilizes blood sugar levels. Theres no one-size-fits-all hypoglycemia diet, but a nutritionist can help you figure out a consistent meal plan tailored to you, and teach you how to count carbohydrate grams to go along with your health and routine.
- Increasing and improving self-monitoring of your blood glucose levels. Knowing your blood glucose level throughout the daywhen you get up, before meals, and after meals etc.can help you keep it from getting too low.
- Limiting consumption of alcoholic beverages. Alcohol interferes with the way your body metabolizes glucose. If you’re prone to hypoglycemia, consider decreasing how much alcohol you consume.
- Glucose tablets . Make sure you always have glucose tablets on hand, whether at home, school, the office, or the gym. After taking the tablet, check your blood sugar. If its still low, take another tablet. If that doesnt help, check with your doctor.

Does Low Blood Sugar Make You Shake Dizzy And Nauseous
Low blood sugar /glucose can generate a number of signs and symptoms. But does it make you nauseous, dizzy, or shake? If so, how do these symptoms occur in hypoglycemia and why? The answer probably is due to the low volume of glucose itself on the bloodstream.
As well we know, the body needs to get a plenty of energy to keep survive. Almost nutrients from foods can give us energy. But glucose has much more contribution than others since it is the most primary component to make energy.
And too low amount of glucose in the blood can be a serious alarm for the fuel of your energy supply.
When you are very being hungry or when exercising without eating enough beforehand, you are likely to feel some uncomfortable symptoms such as nauseous, headache /dizzy, shakiness, and even probably vomiting.
This is perfectly normal because anyone can have them from those situations, therefore dont worry. In such case, the symptoms will go away once the balance of your blood sugar returns.
But in diabetics, this could be more challenging. See here about best foods to eat before exercise if you have diabetes!
Sometimes too low blood sugar would make you shake. Though it is not a specific symptom of hypoglycemia, it is pretty common in people with hypoglycemia.
Hypoglycemia can affect all diabetics. But it is relatively more common in type-1 than in type-2 diabetes.
Furthermore, your shakiness may also be followed with feeling faint and sweating.

Slurred Speech And Clumsiness
Your sugar-starved brain may change the way you sound. Slurred speech is a common symptom associated with blood sugar levels that drop below 40 mg/dL, according to University of Michigan Health Systems. Combined with clumsiness another sign of low blood sugar you may seem as though youve had a few too many cocktails, even if you havent touched a drop, according to the National Health Service.

Vasovagal Syncope As A Cause Of Dizziness
Vasovagal syncope is a common cause of dizziness, lightheadedness, and fainting. The vagus nerve is overstimulated and causes the body’s blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward toward the brain. Without blood flow, the brain turns off. In Victorian England, young ladies’ sensibilities were easily offended causing a vasovagal episode called a swoon.
Some people faint at the sight of blood. Some parents faint when their child gets immunized. Some medical students faint at their first autopsy. Many types of emotional and physical stressors can overstimulate the vagus nerve, causing dizziness, lightheadedness, and at times fainting .
Fainting is not normal. If a person is unconscious, activate the emergency medical system , and seek medical care.

You Notice Tingling And Numbness In Your Hands Or Feet
As mentioned, uncontrolled blood sugar can cause nerve damage, also known as diabetic neuropathy. What you may notice is a tingling sensation or even numbness in your hands and feet. Some people experience pain in their hands and feet as well. Though neuropathy is most common in people who have had diabetes for a long time, it can occur in anyone with poorly controlled diabetes.
How To Check Your Blood Sugar Levels
As Dr. Emanuele says, glucose monitoring can be an important tool to help you get your blood sugar under control. Typically, you would do it yourself using a glucose meter or glucometer, which analyzes a drop of blood that you draw by sticking your finger with a lancet and placing the blood on a disposable test strip that you insert into the meter. Your blood sugar goals are set by you and your doctor, but blood glucose for an adult without diabetes is below 100 mg/dl before meals and at fasting and less than 140 mg/dl two hours after a meal, notes the ADA.
Some people will check their blood sugar daily or multiple times a day, sometimes using a continuous monitor that is worn on the body particularly those who have type 1 diabetes or who have type 2 but take insulin. Yet how frequently a person should monitor their blood sugar is based on a number of factors, including but not limited to whether theyre on insulin, whether theyre taking oral medication, and how well their blood sugar is controlled and how old they are.
Meanwhile, keep an eye out for these nine key warning signs and symptoms that blood sugar is too high and talk to your doctor about whether you need to adjust your management plan.

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.

Can Low Blood Sugar Cause Dizziness
Low blood sugar can cause dizziness beside other symptoms.
- Glucose level < 60 mg/dl with symptoms that are relieved promptly after the glucose level is raised, document hypoglycemia.
- Low blood sugar with dizziness is usually seen in diabetic patients who are on anti-diabetic drugs and insulin and have an insulin overdose accidentally or otherwise.
- The first symptom in these patients is dizziness and disorientation if the blood sugar level decreases.
- Lack of glucose supply to the brain can result in brain dysfunction, like dizziness and if prolonged, leads to irreversible neuronal damage and death.
High Blood Sugar: Hydration
Managing high blood sugar may also help treat dehydration. Drinking plenty of water throughout the day can help the body stay well-hydrated. For more severe cases of dehydration, people may need to replenish their electrolytes.
It is best to avoid sugary drinks or fruit juices, as these could increase blood sugar levels.

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.

Foods That Can Cause Vertigo
Salty foods including chips, pretzels, salted nuts, canned foods, soups, deli meats, pastas, sauces, baking soda, condiments, pizza, baking powder, seasonings, frozen meals, pickles, salad dressings, and cheese can all trigger vertigo. Sodium causes body fluid imbalance. It results in fluid retention in your body and leads to build up of pressure in your inner ear resulting in vertigo. Hence, a diet to prevent vertigo should have very low amount of salt. People suffering from Meniere s disease, which is major cause of vertigo, should consume only 120 mg of salt daily.
2. Sugar Substitutes and Sugar
Foods that have high sugar content such as honey, ice cream, chocolate, maple syrup, dates, jams, jellies, cream, cookies, juices, donuts, cakes, processed snacks, and candy may cause central vertigo. One of the major causes of central vertigo is deficiency of oxygen to the brain. Foods rich in sugar increase blood sugar and blood pressure, though temporarily however, in such condition, blood requires more time to reach brain. This creates a deficiency of oxygen in the brain and cause vertigo. Sugar substitutes such as aspartame may result in various diseases including vertigo.

What Is High Blood Pressure
Blood pressure is the force of the blood pushing against the artery walls. Each time the heart beats, it is pumping blood into these arteries, resulting in the highest blood pressure when the heart contracts and is pumping the blood. High blood pressure, or hypertension, directly increases the risk of coronary heart disease and stroke . With high blood pressure, the arteries may have an increased resistance against the flow of blood, causing the heart to pump harder to circulate the blood.
Two numbers are used to measure blood pressure. The number on the top, the systolic pressure, refers to the pressure inside the artery when the heart contracts and is pumping the blood through the body. The number on the bottom, the diastolic pressure, refers to the pressure inside the artery when the heart is at rest and is filling with blood. Both the systolic and diastolic pressures are recorded as “mm Hg” .According to the National Heart, Lung, and Blood Institute of the National Institutes of Health , high blood pressure for adults is defined as:
140 mm Hg or greater systolic pressure and
90 mm Hg or greater diastolic pressure
NHLBI guidelines for prehypertension are:
120 mm Hg 139 mm Hg systolic pressure and
80 mm Hg 89 mm Hg diastolic pressure
NHLBI guidelines define normal blood pressure as follows:
Less than 120 mm Hg systolic pressure and
Less than 80 mm Hg diastolic pressure

What Are The Symptoms
Some symptoms of hypoglycemia are caused when the body releases extra adrenaline , a hormone that raises blood sugar levels, into the bloodstream to protect against hypoglycemia. High blood levels of adrenaline can make the skin become pale and sweaty, and a person can also have symptoms such as shakiness, anxiety, and heart palpitations .
Other symptoms of hypoglycemia are caused when not enough glucose gets to the brain in fact, the brain is the organ that suffers most significantly and most rapidly when there’s a drop in blood sugar. These symptoms include headache, extreme hunger, blurry or double vision, fatigue, and weakness. At its most severe, insufficient glucose flow to the brain can cause confusion, seizures, and loss of consciousness .
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.
