We’ve always been told to drink plenty of water, and we are familiar with the importance of hydration. But do you ever feel like a thirsty camel gulping down water in a desert oasis? You can’t seem to quench your excessive thirst, even though you’re drinking more than the recommended two liters a day. 

General health, lifestyle, and age can contribute to how much a person drinks. But for a diabetic, it means something different. No matter how much you drink, the thirst and the feeling of a dry mouth can remain. This creates a vicious cycle of drinking and urinating.

For people with diabetes, dry mouth and excessive thirst is the norm. This is a result of diabetic's high glucose levels, whereas their body tries to get rid of the increased sugar in their blood. It does this in two different ways:

  • It absorbs glucose into your cells for energy.
  • It flushes the glucose out of your body completely.

While both reflect proper body function, one of these methods is what’s likely causing your increased thirst and dry mouth. Excessive thirst is a sign of diabetes. It is also medically called polydipsia. Thirst is linked to another common symptom of diabetes that is related to urinating more than normal or polyuria.

Is drinking a lot of water good for diabetics?

Excessive thirst and increased urination are common symptoms of diabetes. Increased blood sugar forces your kidneys to work harder than usual to keep your glucose levels in balance. Once your kidneys can’t keep up, your body will try to flush the increased glucose out of the body through urine. This will usually leave you feeling thirsty.

Drinking water helps to rehydrate the blood when the body tries to remove high levels of glucose through urine. That’s why diabetic patients urinate so often. Frequent bathroom breaks can lead to dehydration, leaving you with an excessive thirst for water.

This is your body’s way of telling you to replace the fluids it has just flushed. Increasing the amount of water intake can soothe these symptoms. You can always consult with your doctor for advice on how much water you individually need per day.

Why am I always thirsty even though I drink a lot of water?

Abnormal urination and thirst, unexplained hunger, fatigue, unexplained irritability, including the presence of ketones in the urine, and sometimes even blurred vision can be an early sign of diabetes.

If you’re constantly thirsty, the first step should be to go to a doctor to check if your thirst is a result of diabetes. 

The most common symptoms of diabetes are often referred to as The Three P's of diabetes. There are several ways to diagnose diabetes. One of those are:

  1. Random blood sugar test.
  2.  Fasting blood sugar test.
  3. Oral glucose tolerance test.

Three P's of diabetes

  • Polydipsia: is a medical term that indicates an intensification of thirst. The person with polydipsia will drink more than 5L of fluid during a day.
  • Polyphagia: an increase in appetite;
  • Polyuria: repeated urination;

Do diabetics dehydrate faster? Why do people diagnosed with diabetes have an increased risk of dehydration?

Diabetes and dehydration can be a dangerous combination. However, the good news is that few simple steps can stop the vicious cycle of dehydration and high glucose.

Excess blood glucose levels lead to decreased hydration in the body.

  • Your body is trying to maintain balance.  When fluid disappears from one place, your system is fighting it by trying to replace it using water from your bloodstream.
  • When there is less water in your bloodstream the volume of your blood is shrinking and blood sugar will rise. High blood sugar, as you know, leads to insulin resistance and further blood sugar increase.
  • High blood sugar causes further dehydration which creates this vicious cycle to repeat.

Diabetic Thirst: What is it and how can you fix it?

According to the advice of The Harvard Medical School Special Health Report, for your body systems to function properly, a person should stick to four to six cups per day. While there may not be a definitive answer to this, here are certain recommendations you can follow.

How is diabetes thirst different from Type 1 and Type 2 diabetes?

Both types of diabetes can cause similar symptoms if they are not treated.

How can you fix increased thirst?

The amount of necessary water intake varies from person to person.  It is enough to simply have access to drinkable water each time you feel thirsty throughout the day. You will need increased amounts of water if you exercise and sweat or if you're outside on a hot day or if you’re eating spicy foods throughout the day or if you are not eating enough water-containing foods.

The thirst reflex isn't always perfect. It's easily mistaken for hunger. Symptoms that overlap can easily lead to confusion when it comes to feeling hunger and thirst. Pay close attention to these feelings when you have them and think about what you have eaten or drank so far during the day. 

Also, it is very important to pay attention to the color of your urine. The color of your urine is a true indicator of your body's hydration level. The urine color of a well-hydrated person is pale yellow or clear. If it’s dark yellow, this a good indicator you may need much more water in your system.

To eliminate dehydration, it is recommended to gradually drink fluids throughout the day.

What are the ways to remember to drink water throughout the day?

  • Carry a water bottle with you
  • Keep a water journal
  • Find an alternate beverage

Is water the only option for quenching excessive thirst?

Researchers have found that the amount of water you drink can play a significant role in how your body regulates blood sugar. If you’re looking to quench your thirst, you should be cautious with soda or juice. These drinks are often high in sugar, which may trigger a spike in your blood levels and make your thirst even worse.

You can do your research on what home-made type of diabetic drinks you can consume considering that most of the beverages sold in stores contain high doses of added sugar. But it is always good to tell your doctor and seek his or her advice on it. This is simply because certain diabetic drinks may not suit your diabetic condition. Once you consult with your doctor, you can prepare these drinks at home and stay healthy.

In moderation, you can enjoy caffeinated and alcoholic beverages. But first, you should always choose water, nature’s best. This is simply because water does not have calories, added sugars, and it's the most accessible and necessary liquid for your overall health and wellness.

How to manage diabetes thirst in the long run?

Until the underlying problem of elevated glucose levels is addressed, frequent urination will remain an unsolved issue. That is why treating the frequent urination and thirst problems stemming from diabetes is the best to approach treating the condition holistically.

People with type 1 and type 2 diabetes need to keep a close eye on their lifestyle and respect the routine of personalized doctor treatment and regime. Being optimistic and motivated can make a significant difference. Join our support community. Keep in mind to regularly:

Follow a healthy diet plan

Make sure to include non-starchy vegetables in your diets, such as broccoli, spinach, and green beans, and leafy greens. Include fewer added sugars and refined grains, such as white bread, rice, and pasta with less than 2 grams of fiber per serving. Don't forget to balance out each meal with the proper amount of protein and dairy. An eating plan is usually prescribed by doctors, which is usually low in fat and calories and high in nutritive value.

Stay hydrated

The glucose in your bloodstream is getting more concentrated due to dehydration. Drinking enough water will impact so many aspects of your overall health.

Monitor your blood sugar and insulin injections

As a type 2 diabetes patient, you may need to check your blood sugar levels several times a day. Make sure they don't get high or low and keep a record of it. Take insulin as prescribed. Considering diabetes can affect the function of your whole body, your healthcare providers should also regularly test your:

  • Kidney health (urine and blood testing)
  • Heart health (blood pressure, weight, and cholesterol level)
  • Foot health (foot exams and sensory testing)
  • Eye health (eye exams)

Establish an exercise routine

An established exercise routine improves blood glucose control in type 2 diabetes, can reduce cardiovascular risk factors, improve your overall well-being, and help contribute to weight loss. Development of Type 2 diabetes can be prevented and delayed with regular exercise. Managing diabetes and fitness goes hand in hand. You can always try walking, yoga, swimming, or other aerobic exercises. For more exercise ideas you can always consult with a doctor.
