Does High Blood Sugar Cause Nausea


Why Are Diabetes And Headaches Linked

Feel Nauseous in the Morning? Skip Breakfast? This Could be a Sign of Blood Sugar Problems.

In essence, diabetes and headaches are linked because the high or low blood glucose/sugar associated with diabetes results in changes in the head. For more detail, lets get our heads round the main causes!

Hyperglycemia

Hyperglycemia is when blood glucose levels rise above 7.0 mmol/L or 126 mg/dL. One of the typical symptoms of high blood glucose is a headache.

There are a few different reasons why this happens. The first is low energy. For people with diabetes, their own insulin is not doing the job of making glucose enter the cells .

Without that glucose, the body doesnt get the energy it needs. And without that energy, the body isnt getting the fuel it needs to function. This includes the brain headaches can be a sign that the brain isnt getting energy.


Hyperglycemia can also cause headaches because of dehydration. Essentially, the body tries to flush the excess glucose out through the urine, meaning more bathroom visits, and less fluid in the body. The brain needs fluid to function.

A headache being a signal of high blood glucose is such that people who havent been diagnosed with diabetes should always be aware. A headache could be one of the tell-tale early signs of diabetes.

Hypoglycemia

Hypoglycemia is the opposite of hyperglycemia. Its where blood glucose is too low: below 4.0 mmol/L or 70 mg/dL. Low blood glucose and headaches are equally concerned with low energy.

Poor sleep
  • Nightmares or crying out during sleep
  • Seizures

Management Of Refractory Dgp

Unfortunately, many patients with DGP will not experience adequate symptom relief despite education, dietary manipulation, and the use of prokinetic and antiemetic drugs. Thus far, there is no consensus on the proper treatment of patients with refractory disease. The therapeutic options available for these patients include combination prokinetic therapy, psychotropic medications, pyloric botulinum toxin injection, and gastric electric stimulation. Combination prokinetic therapy would involve agents that act via different mechanisms to enhance gastric emptying however, it should be noted that combination therapy has not been specifically studied for gastroparesis of any etiology. In a subset of patients with severe nonmedically responsive gastroparesis, feeding tubes or surgical interventions might be considered.

The efficacy does not appear to differ between tricyclic preparations. The key to this treatment approach is to go slow and low. The starting dose is usually 10 mg, taken 2 hours before bedtime. If the patient tolerates this dose, it can be progressively increased up to 50 to 100 mg. The low-dose tricyclics are usually well-tolerated, although excessive sedation and dry mouth occasionally limit its use. If these events occur, it may be helpful to switch to nortriptyline or desipramine, which are thought to have a lower incidence of adverse events.


Is Diabetes To Blame For Your Headache

Take control of pain

Diabetes is a chronic metabolic disease that results in blood sugar, or glucose, abnormalities. This causes a host of symptoms and related complications, some of which can be life-threatening. A common symptom of high or low blood glucose is a headache. Headaches alone arent harmful, but they can signal that your blood sugar is out of its target range.

Headaches are classified as being primary or secondary. Primary headaches occur when brain cells or nerves, blood vessels, or muscles around the head send pain signals to the brain. Migraines and tension headaches are common examples.

Secondary headaches, on the other hand, are not directly caused by the type of pain signals mentioned above. These types of headaches are attributed to underlying health conditions or medical problems. Diabetes is one cause of secondary headaches. Other causes can include:


  • fever or infection
  • high blood pressure, or hypertension
  • stroke
  • hormone fluctuations, such as those occurring during menstrual cycle
  • eye disorders
  • structural abnormalities within the brain

Parents Of Children With Diabetes

If your child has diabetes and shows symptoms of hypoglycemia, it’s important to check their blood glucose level with a glucometer. If this is not possible, it is best to treat them as if they have hypoglycemia by giving them carbohydrates to prevent symptoms from getting worse.

Your child should have a safety plan in place for when they are not in your care, such as when they are at school, friends homes, or daycare. The plan should include whom they should talk to if they are not feeling well.

Talking to your child about their diabetes and the symptoms to be aware of helps keep them safe.

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.

What Is Type 1 Diabetes

Does High Blood Pressure Cause Nausea or Dizziness?

Type 1 diabetes, sometimes known as juvenile diabetes, is a chronic autoimmune condition in which your pancreas loses the ability to produce insulin. It can be triggered by a virus, such as the common cold or flu, and there is evidence that it has a genetic component as well.


Following a viral infection, your body can sometimes malfunction and respond by attacking its own cells. This process is known as an autoimmune response. In type 1 diabetes, your bodys immune system specifically attacks cells in your pancreas called beta cells, which produce the hormone insulin. In that case, damaged beta cells mean your body either stops producing enough insulin, or it cant produce insulin at all.

Tips For Tracking Your Blood Sugar Patterns And Using Your Results

Diabetes Throwing Up

Here are some great tips:

Have a blood sugar chart on your phone or a written notebook nearby to compare your numbers

For my patients during the class entitled, Monitoring your Blood Glucose, I pass out individual notebooks, and packs of different colored highlighter pens for pattern management. Inside, there are copies of an enhanced blood sugar log.

Patients log their blood sugars at different times of the day, and color-code them with highlighters. This helps patients to pick out their blood sugar patterns, and to do different things to adjust their blood sugars to get them in a target range.

Patients may either take a walk following a high carbohydrate meal, take more insulin if they are correcting blood sugar with insulin, decrease the amount of carbohydrates at the next meal, etc. By seeing what their blood sugars are at different times of the day, they can work their blood sugars into their target ranges. Once blood sugars are in the target range, their A1C should also be on target.


I have included a copy of the enhanced blood sugar log that I use to make a pattern notebook for my patients. Readers here at TheDiabetesCouncil are welcome to copy the form for their own use in self-managing their diabetes. You can also download our comprehensive log book here.
