Can Dehydration Cause Low Blood Sugar

What To Do Next

Dehydration | Habits That Cause HIGH BLOOD SUGAR!

Using the 15/15 rule, after eating 15g of fast-acting carbohydrates, test or re-test your blood glucose with a glucometer after 15 minutes.

If your blood glucose is still less than 4.0 mmol/L, consume another 15g of fast-acting carbohydrates, re-test blood glucose, and repeat as long as your blood glucose does not rise more than 4.0 mmol/L.

If your blood glucose is more than 4.0 mmol/L, look out for your blood glucose level as it may fall again after 1 hour.

You may eat an additional food containing 15g of long-acting carbohydrates such as biscuits or bread .

Everyday Dehydration Is Having A Major Effect On Your Blood Sugar Levels

Stop and think for a second: Are you dehydrated right now? Are you sure? According to the Institute of Medicine, 75 percent of Americans live with a condition called chronic dehydration. This means that even though youre drinking fluids throughout the day, your body still isnt getting the amount it needs to thrive. In fact, chronic dehydration is so common that our bodies get used to it. Thats why you may not feel thirsty, even when your cells are craving some much-needed H2O.

People with diabetes are especially prone to daily dehydration. As glucose builds up in the bloodstream, your kidneys are forced to work extra hard to filter out the excess sugar. If they cannot keep up, that sugar is flushed out of your system through urine. High blood sugar can also cause your body to pull fluids from important tissues, such as the lenses of your eyes, muscle tissue, and brain tissue.

If left untreated, everyday dehydration can take a pretty serious toll on your blood glucose levels. When your body is lacking fluids, it creates a hormone called vasopressin, which causes your kidneys to retain as much fluid as possible. By keeping in those liquids, your kidneys are also hoarding unwanted glucose. On top of that, high levels of vasopressin in your bloodstream can also cause the liver to produce additional blood sugar. Over time, this can lead to consequences like insulin resistance and chronic hyperglycemia.

Treatment And Management Of Low Blood Pressure

Determining the cause of low blood pressure is the first step in managing it. For example, if the cause is dehydration from excess fluid losses, getting better control of your blood sugar and staying well-hydrated can help.

For people who get low blood pressure after a meal or after sitting or standing , the following may help:

Avoiding large meals and eating more frequent smaller meals
Drinking plenty of fluids, and avoiding beverages with a high sugar content
Avoiding standing for long periods
Avoiding alcohol
Standing up slowly
Using compression stockings or socks

If you feel faint or experience dizziness, it’s always safest to sit or lie down. This will help to avoid injury in the event of falls or fainting. In autonomic neuropathy, other treatments might be required, such as medications that can help raise blood pressure .

Dehydration And Diabetes Insipidus

Diabetes insipidus is a particular form of diabetes in which the body is unable to properly regulate the amount of water in the body.

Unlike other types of diabetes, diabetes insipidus is not connected with higher than normal blood glucose levels.

The symptoms of diabetes insipidus include passing large amounts of urine and feeling very thirsty.

If the body is passing too much urine, dehydration can result. In diabetes insipidus, dehydration is treated by taking on fluids.

People with diabetes insipidus may be advised to drink a specific amount of water each day and may be advised to take specific fluids that contain electrolytes if dehydration occurs.

What About The Glycemic Index

Your daily carb total, spread steadily across the day, is one key to good blood sugar control. Some people also use the glycemic index , a rating of how individual foods raise blood sugar levels. Beans and whole-grain breads and cereals have a lower GI than white bread and regular pasta. Juice has a higher GI than whole fruit. Craving a high-GI food? Eat it along with a lower-GI choice to help control your levels.

How Much Water Should You Drink Every Day

Each person has a different correct daily water consumption requirement. It depends on a number of variables, including your weight, level of physical activity, etc.

Based on your unique health situation, talk to your doctor about how much water you should consume each day. Your doctor can examine your medical history, speak with you about your lifestyle, and use this information to determine the best course of action.

Time Of Day Affects Blood Sugar Levels

Time of day can have a surprising impact on glucose levels. It’s because the bodyâs circadian rhythm can affect glucose metabolism.

Blood sugar levels can often be higher in the morning for those with diabetes, likely because of lower insulin levels and the release of hormones.

Itâs essential to work with a doctor or medical professional if you are someone who experiences abnormal blood sugar levels during the night and early morning. It will help you determine what factors may be contributing to these fluctuations.

The food which are high in fructose and added sugar are carbonated drinks and beverages, fruits and vegetables like banana, kiwi, cherry, blackberry, mango, tomato, dates, asparagus, beans, broccoli, etc., processed foods like barbeque and pasta, dried fruits, etc. Thus a person who is at increased risk and also those who are already suffering from hypertension must be cautious about the intake of added sugar or fructose in their diet. These people must also try to avoid the processed and packed foods which are generally very high in added sugar. Moreover, in contrary to the earlier belief, they should include salt in their diet so as to utilize its positive effects on the body. However, the quantity must not exceed the limit.

How Can You Lower Blood Sugar Level

Everyone knows that water is a natural source of detoxification and keeping yourself hydrated will help you cleanse your system. But the question is how does hydration help in lowering blood sugar levels? People suffering from diabetes comparatively require more water to keep themselves hydrated. This helps the kidneys to flush out the excess sugar levels by urinating. The best part of this hydration process is that it will not raise the blood sugar levels, as water does not contain any fat, glucose or carbohydrate for that matter. Thus, you even quickly lower the increased blood sugar levels.

The Importance Of Water In Human Beings

All human beings require a certain amount of water for survival. But why is it so essential? Well, for one, it helps carry nutrients and oxygen to cells in the body and supports brain, heart, kidney, liver, skin, and skin health. Staying hydrated can also help keep you satiated and can lower the risk for obesity in adults.

When you donât drink enough water, you may see impacts on some aspects of cognitive function like vigor, memory, and your ability to pay attention. One study even found evidence suggesting that staying hydrated throughout life can lower your risk of heart failure.

Here is a closer look at how dehydration and high blood pressure are related.

When you have high blood pressure, your blood pushes hard against the walls of your blood vessels because it has a higher pressure than usual.

Can dehydration cause high blood pressure? High blood pressure might be a result of dehydration. Your body produces more of the chemical vasopressin when you are dehydrated.

The Bottom Line

Different Diabetes And Kidney Disease

How Does Dehydration Affect Blood Glucose Levels?

Kidney disease is another common complication that occurs during diabetes. Dehydration during diabetes leads to the formation of kidney stones, urinary tract infections.
High blood glucose levels also called high blood sugar will damage the blood vessels in the kidney due to excessive pressure. The damaged blood vessels do not work properly leading to diabetic kidney disease or kidney failure.
Your urine will change to be dark-colored and you urinate less than usual. Depending on the age, climate, physical activity, gender, diseased state, or special condition like pregnancy you need to change the water intake.
Even the use of certain medications can cause kidney disease during diabetes which becomes more complicated. With increased blood sugar levels and increased blood pressure, there are more chances of developing kidney failure.

To manage this, you need to avoid-

No exercise day

People with diabetes are more prone to heart diseases and other kidney diseases like polycystic kidney disease. So, the best way is to take more glasses of water, have regular check-ups on blood glucose levels, control blood pressure, healthy lifestyle, and regular medicine consumption.

Never neglect the water intake even if you are not a kidney patient, to avoid its occurrence in the future. Take steps to lower your blood glucose levels with a proper diet and medication.

Should People With Diabetes Drink Sports Drinks

Maybebut it depends on several factors.

For the average exerciser, research has determined that simply drinking water is more than enough to keep you well-hydrated during a workout and throughout the day.

On the other hand, sports drinks with electrolytes and carbohydrates can be helpful for maintaining hydration levels during lengthy types of exercise .

However, the biggest exception here is if youre using those carbohydrates to keep your blood sugar steady. Researchers have found the gradual consumption of carbohydrates from sipping a sports drink can help prevent low blood sugars during aerobic exercise.

Whos At Risk Of Becoming Dehydrated

Anyone can become dehydrated if they dont take care of themselves and drink water. However, infants and children, especially when theyre sick, are at a higher risk because they may be unable to communicate that theyre thirsty. Monitor the amount of fluids your kids take in.

Older adults are also at a higher risk. Their bodys fluid reserves shrink and their bodys ability to tell them theyre thirsty doesnt work as effectively. This means they dont carry as much water in their bodies and they cant tell as easily when theyre thirsty. If youre a caretaker of an elderly individual, especially one who may have memory problems, offer them drinks frequently. Even if theyre enduring an uncomfortable infection like a UTI , they still need to consume liquids.

What Are The Complications Of Diabetes Insipidus

The main complication of diabetes insipidus is dehydration, which happens when your body loses too much fluid and electrolytes to work properly. If you have diabetes insipidus, you can usually make up for the significant volume of fluids you pass in your urine by drinking more liquids. But if you dont, you could quickly become dehydrated.

Dehydration is dangerous and can be life-threatening. If youre experiencing symptoms of dehydration, such as feeling dizzy, nauseous and sluggish, get to the nearest hospital as soon as possible.

The Difference Between Low Blood Sugar And Dehydration

How Hydration Affects Blood Sugar Levels

Do you know the difference between low blood sugar and dehydration symptoms? Here are some similarities and differences. Once you know what the cause of the symptom is, then you can know how to fix it. This is what I do with clients. I help them know what those symptoms are and why they are happening. Once we know in this case whether it is caused by low blood sugar or dehydration, we create a plan to correct the issue. I referred to the Health Line and ADA websites for symptoms of low blood sugar, also known as hypoglycemia. I will try to differentiate the difference between low blood sugar and dehydration:

Shakiness this is low blood sugar but does not happen with dehydration.

Rapid heart rate I have not witnessed this as a low blood-sugar issue, but since both sites list it, rapid heart rate must be a symptom! In dehydration, the heartbeat will also climb and be jumpy in the higher ranges. This erratic and high heart rate is a sure sign of dehydration.

Fatigue This is a symptom of both. With low blood sugar, you typically crave caffeine and need a boost of energy. If you check the time since your last meal, it may be a clear indication you need to just eat, not grab a nap or a cup of coffee. In dehydration, you feel like the wind got knocked out of your sails and you can no longer go at the same pace. It is usually matched with despondency and the desire to go lie down under a tree in the shade and sleep.

Effect Of Dehydration On Renal Function Tests

Dehydration has multiple effects on the kidney. The loss of body water leads to an increase in serum osmolality and activation of vasopressin which results in urinary concentration. This can be seen clearly in the above given Vignette.

Nose and colleagues also demonstrated sustained effects on plasma electrolyte concentration before and after dehydration .

Figure 2

However, there is an exception in the case of patients with cranial diabetes insipidus .

Dehydrated patients usually present with an elevated serum urea level, owing in part to increased renal reabsorption of urea mediated by antidiuretic hormone . Serum urea values fall in patients with ADH deficiency and this fact can be used to distinguish patients dehydrated because of CDI from those with usual hypertonic dehydration and intact ADH secretion. In one study, the mean serum urea level was 2.9 mmol/L in the CDI group and 15.4 mmol/L in the patients without CDI, while the mean serum sodium level was 155 mmol/L in both groups.

Why Is Water Important To Your Body

Water helps in –

Control body temperature
Shock absorber of the brain, spinal cord, and fetus

Water is lost from the body as sweat when your body temperature is raised by exercise, fever, and warm weather. Loss of water or fluids from the body will reduce the body water level and lead to dehydration.

What Can Make My Blood Sugar Rise

Hyperglycemia is the technical term for high blood sugar . It happens when the body has too little insulin or when the body canât use insulin properly. Here are a few of the causes:

Too much food, like a meal or snack with more carbohydrates than usual
Not enoughinsulinor oral diabetes medications
Side effects from other medications, such as steroids or anti-psychotic medications
Illness, stress, menstrual periods or short or long-term pain

The good news is, there are things you can do to avoid highsand to treat them when you get them.

Effect Of Dehydration On Blood Glucose

One study has looked at the effect of dehydration in frogs and demonstrated that dehydration can increase blood glucose levels. The rise in glucose was found to be out of proportion to changes in metabolite concentrations that could be due to passive concentration of the plasma as a result of dehydration. Glucose was significantly elevated even in 12.2% of dehydrated frogs and rose progressively to a final level 23.6 times higher than controls in 50% of dehydrated frogs.

Another study showed an increase in hepatic glucose production, with increased plasma glucose levels during hyperosmolality which can be caused by dehydration. The very high levels of venous glucose seen in patients with Hyperglycaemic Hyperosmolar State often resolve rapidly with rehydration alone without the need for insulin. This would suggest a significant effect of dehydration on venous glucose concentration.

Insufficient Sleep Can Throw Blood Sugar Out Of Whack

Restless nights hurt more than your mood and energy they may also spell trouble for your blood sugar. A review published in December 2015 in Diabetes Therapy concluded that a lack of sleep may hinder glucose control and insulin sensitivity in people with type 2 diabetes.

“Sleep is restorative,” Bonsignore says. “Not getting enough sleep is a form of chronic stress on the body, and anytime you have added stress, you’re going to have higher blood sugar levels.”

Unfortunately, people with type 2 diabetes commonly report troubles sleeping, McDermott says. Those with high body-mass indexes are at particular risk for sleep apnea, in which breathing frequently starts and stops during sleep.

To improve your sleep quality and duration, work to get into a consistent sleep routine where you go to bed and wake at the same time every day. Your goal: Nab seven to nine hours of sleep per night, per recommendations from the National Sleep Foundation. If you continue to have sleep troubles or suspect you have sleep apnea , reach out to a sleep medicine specialist for support, Bonsignore says.
