Did you know that water makes up more than half of the human body? It's no wonder why staying hydrated is important for everyone!

As Dr. Roberta Lee explains, "60 percent of our body is composed of water, 75 percent in our muscles, 85 percent in our brains." Water for our body is like oil for a machine.

However, recent research has found that Americans are not drinking enough water. In fact, the American Institute of Medicine says that 75% of Americans are constantly dehydrated.

This is especially worrisome for people with diabetes because severe dehydration affects blood sugar levels.

Severe dehydration can have a serious impact on blood glucose levels, so it's important to stay hydrated throughout the day. As a diabetic, are you having enough water? Or should you limit your water intake?

If you are not a fan of plain water, what are the best water alternatives available for you? This article will explain all of that and more.

What Are The Impacts of Water on Your Diabetes?

The effects of water on diabetes are multifaceted. Staying hydrated can help you lower your blood sugar, reduce the risk of dehydration-related health problems, increase energy levels, and even aid with weight loss.

However, for some people with a specific health condition, drinking too much water can also have a negative impact on diabetes management.

The Dangers of Diabetes and Dehydration

When people experience moderate dehydration symptoms such as dry lips and thirst, this is often one of the early signs of diabetes. But how exactly are dehydration and diabetes related?

For patients with diabetes mellitus, dehydration can be extremely harmful. Something simple as mild dehydration, which often goes unnoticed, can elevate your blood sugar levels by 50 to 100 mg/dL.

Similarly, If you've diabetes and you're frequently dehydrated, this might be because you're using more insulin than necessary. Adequate hydration is crucial for maintaining healthy blood sugar levels.

The Diabetes Insipidus Condition

Diabetes insipidus is a rare condition that affects the kidneys' ability to conserve water. People with this condition produce high amounts of urine and may become severely dehydrated due to lost fluids. As a diabetic, it is extremely important to maintain a healthy fluid balance.

The Excessive Thirst Condition

Excessive thirst, also known as polydipsia, is one of the early symptoms of diabetes. By urinating more frequently than usual due to high blood sugar, you can become dehydrated and still feel thirsty.

This happens because your kidneys make more urine to wash out the excess glucose in your body. Once your blood sugar levels start to go down, this cycle will end.

The Diabetes Ketoacidosis Condition

People with type 1 diabetes are more likely to experience diabetic ketoacidosis (DKA) after having high blood sugar levels.

When your body cannot process sugar properly, it begins to break down fat for energy instead. This creates ketones, which are a sort of acid. Having too many can cause serious problems like a decrease in your fluid level.

Some warning signs include:

  • Flushed face
  • Muscle stiffness
  • Headaches
  • Vomiting
  • Dry skin
  • Diabetic coma

The Symptoms And Causes of Dehydration

Dehydration occurs mostly when you lose more fluid than you take in.

Symptoms may include:

  • Thirst
  • Headache
  • Fatigue and dizziness
  • Dry mouth, lips, and eyes
  • Dark yellow urine
  • Abnormal Heartbeat

The causes of dehydration may vary, but the most common are:

  • Hot Temperature
  • Not drinking enough fluids
  • Excessive sweating
  • Diarrhea or vomiting
  • Fever
  • Drinking Alcohol

As a Diabetes, How Much Water Should Be Drinking Daily?

How much water should you be drinking daily as a diabetes

Although there is no concrete rule for how much water one person should drink, we can follow some broad guidelines.

The most important suggestion is to always have water accessible and to drink it when you feel thirsty.

You don’t need to make yourself consume a specific amount of water per day, but rather try a few sips regularly throughout the day.

Although you may not feel thirsty, it's still essential that you drink water regularly throughout the day to prevent dehydration.

The thirst reflex isn't always accurate, especially for people with diabetes, so it's better to proactively drink small amounts of water every hour.

The average person without diabetes is advised to drink 8 glasses of water a day, so those with diabetes should take that number to heart or else suffer the consequences in their blood sugar levels.

Diabetic women need 1.6 liters (L) of water a day, or 6 and a half cups, and men require 2 liters of water a day which is equivalent to 8 and a half glasses per day.

Both diabetic and non-diabetic water needs will differ based on outside temperature and how active they are. As a general rule of thumb, someone exercising or in hot weather need to consume more water than recommended above.
