Why Does My Water Taste Sweet? 8 Possible Causes

Reasons Why Water May Taste Sweet

Water is essential for life, but it usually has a neutral taste. However, sometimes water can take on a sweet taste for various reasons. Understanding what makes water taste sweet can help ensure your drinking water tastes fresh and appealing so you get enough hydration.

Medical Conditions That Can Make Water Taste Sweet

In some cases, a sweet taste in water can indicate an underlying medical condition. Being aware of these potential causes can help you determine if your changing taste sensations warrant seeing a doctor.

• Diabetes - High blood sugar levels in diabetes can make water and other liquids taste sweet or syrupy. This is due to extra glucose building up in bodily fluids like saliva and tears. If water starts tasting sugary, it may be a sign diabetes is not well controlled.
• Pregnancy - Hormonal changes during pregnancy can make water and other typically bland drinks taste sweet or metallic. This is called dysgeusia and is often described as a metallic or chemical taste. If you suddenly notice water tastes sweet, it may indicate pregnancy, but other causes should be ruled out.
• Medications - Certain prescriptions and over-the-counter medications can alter taste perception and make plain water taste sweet. These include antibiotics, antidepressants, antihistamines, and antipsychotic drugs. If water tastes sweet after starting a new medication, notify your doctor.
• Sjögren's syndrome - This autoimmune disorder affects moisture-producing glands in the body, including saliva glands. Dry mouth from Sjögren's syndrome can make water seem syrupy sweet. Other related symptoms include dry eyes, joint pain, and fatigue.
• Respiratory infections - Sinus infections, strep throat, and COVID-19 can make water and other beverages taste sweet or odd. Any respiratory infection that causes inflammation in the nasal cavities can potentially lead to dysgeusia.

In most cases, sweet-tasting water due to a medical condition resolves once the underlying problem is treated. But if an unexplained sweet taste in water persists, visit your doctor to pinpoint the reason.

Problems With Your Water Source

Strange tastes from your tap water, including sweetness, can also indicate issues with your water source or plumbing:

• Contaminants - Bacteria, chemicals, metals, and minerals in drinking water can impart sweet, salty, or metallic tastes. Common water contaminants that can make it taste sweet include mercury, manganese, and aluminum.
• Plumbing issues - Old or corroded pipes and fixtures can leach metals into tap water, potentially causing a sweet, bitter, or chemical taste. Water sitting stagnant in your home's pipes can also start tasting sweet.
• Municipal water treatment - Chemicals used to disinfect public water supplies, like chlorine, can react with organic material and make tap water taste sweet. High mineral content in municipal water may also leave a sweet aftertaste.
• Natural groundwater quality - Well water or naturally sweet mineral springs can have high concentrations of minerals that lead to a sweet, salty, or alkaline taste.

If you notice your tap water has an unusual sweet flavor, try flushing the pipes and water tanks to freshen the supply. Use filters to remove chemicals or metals imparting sweet tastes. You can also test your water to identify any problematic contaminants.

Foods or Drinks Before Tasting Water

Eating or drinking something sweet before sipping water can make your next drink of water seem sweet too. This temporary dysgeusia occurs because the sweet flavors coat your taste buds and affect your perception of the next beverage.

Beverages that can make water taste sweet afterward include:

• Fruit juice
• Sweet tea or coffee drinks
• Soda
• Sweet wines or cocktails
• Milk and dairy drinks

Sugary foods that can make water taste sweet later on include:

• Candy
• Cookies
• Cake
• Other baked goods
• Sweet cereals
• Jams, jellies, and preserves
• Fruits like mangos, pineapples, figs, and dates
• Sweet sauces and dressings

The best way to combat this effect is by rinsing your mouth with plain water after consuming anything sweet. You can also switch to unsweetened beverages and foods during mealtimes.

How Your Saliva Affects Taste

Saliva helps moderate flavors in your mouth, including sweetness. Changes happening in your saliva could potentially make water taste sweet at times.

Causes related to saliva include:

• Dehydration - Being dehydrated produces less watery saliva, allowing sweetness and other tastes to concentrate.
• Low saliva flow - Certain medications, autoimmune disorders, and radiation therapy can reduce saliva output, affecting your ability to taste.
• Pregnancy - Hormonal changes increase sweet sensitivity and make water taste sweet before you even take a sip.
• Sweeteners - Artificial sweeteners like aspartame leave a sweet taste that may carry over to water.

Boosting hydration, avoiding sweeteners, and using sour flavors like lemon can help overcome temporary taste changes related to saliva. If poor saliva flow persists, your doctor may prescribe medications or recommend techniques to stimulate more saliva production.

How to Make Water Taste Less Sweet

If you want to make unsweetened water seem more neutral or appealing, try these easy fixes:

• Rinse your mouth with plain water before drinking to clear any lingering sweetness.
• Add a squeeze of lemon, lime, or other citrus juice - tartness counters sweetness.
• Include fresh mint leaves, cucumber slices, or ginger - these have clean, refreshing flavors.
• Pour water over ice - the chilled temperature makes sweetness less pronounced.
• Use a straw - letting water bypass your mouth's taste receptors reduces perceived sweetness.
• Filter your water - devices like Brita pitchers help remove off-tastes.
• Switch to bottled spring or mineral water - different water sources have different mineral contents.

Keep sipping throughout the day to stay hydrated, even when water briefly tastes sweet. Pay attention if an unexplained sweet taste persists - your body may be giving you important signals about your health.

When a Sweet Taste in Water Might Indicate a Health Issue

Most of the time a sweet taste in plain water is nothing to worry about. But occasionally it could be a sign of an underlying medical condition that needs attention. Contact your doctor if you experience any of the following:

• Water consistently tastes sweet, not just temporarily after eating or drinking something sugary
• Other symptoms like excessive thirst, frequent urination, vision changes, or numbness in the hands and feet
• The sweet taste in water gets progressively worse
• Water tastes metallic, bitter, or odd in addition to sweetness
• You've recently started a new medication or changed prescriptions
• You have a respiratory infection accompanied by lost sense of smell
• You have dry eyes, mouth, or skin that won't improve with hydration

Some of the conditions that could potentially cause sweet-tasting water include:

• Diabetes - Uncontrolled blood sugar allows excess glucose to build up in bodily fluids, making water taste sweet.
• Pregnancy - Hormone changes during pregnancy heighten sensitivity to sweet tastes.
• Sjögren's syndrome - This autoimmune disease decreases saliva production, altering taste.
• Respiratory infections - Sinus trouble or COVID-19 can make water taste sweet due to inflammation.
• Medications - Antibiotics, antidepressants, and other drugs may list altered taste as a side effect.
• Dental issues - Problems like infections, dry mouth, or oral appliances can affect taste.
• Water contaminants - Metals like manganese or aluminum sometimes dissolve into drinking water and make it sweet.

In many cases, finding and treating the underlying problem will also resolve strange taste sensations like sweetness. But be sure to keep your doctor informed if any odd tastes in water linger or get worse rather than improving over time.

Tips for Making Plain Water Taste Better

While sweet-tasting water is not ideal for regular hydration, there are many ways to give plain water a flavor boost so it tastes more appealing. Try these healthy ideas:

Infuse with Fruits and Herbs

For wholesome, naturally sweet flavor, add sliced fruits like lemon, lime, orange, watermelon, strawberries, cucumber, or pineapple to your water. You can also infuse water with fresh herb sprigs like mint, basil, rosemary, or lavender.

Make Fruit-Flavored Ice Cubes

Freeze juices, purees, or pieces of your favorite fruits into ice cubes to add light sweetness and flavor as they melt into your water. Try mangos, peaches, berries, pineapple, or pomegranate.

Use Natural Sweeteners

A touch of honey, maple syrup, agave nectar, or stevia can enhance plain water’s flavor slightly without overdoing added sugars. But use sparingly, as the sweetness can accumulate.

Mix with Fruit Juice

For an appetizing sweetness, dilute small amounts of 100% fruit juice into your water. Try tart juices like cranberry, pomegranate, cherry, or orange to cut the sweetness.

Make Fruit-Infused Tea

Brew flavorful yet unsweetened teas using dried fruits, berries, peels, spices, and herbal teas. Chill teas before mixing a bit into your water.

Blend with Fruit

Make fruit-flavored water by blending strawberries, kiwi, melon, grapefruit, or other cut fruit with water in a blender, then strain out pulp if desired.

Liven with Citrus

Sparkling waters mixed with squeezed lemon, lime, grapefruit, or orange slices add zest and refreshing fruit flavors to water.

Add Flavored Ice Cubes

For light flavor without sweetness, freeze mint leaves, sliced ginger, rosemary, cucumbers, or lemon rinds into ice cubes to pop into your water.

With endless options for producing tasty infused waters at home, you can stay hydrated without adding unnecessary sugars or turning to artificially flavored beverages. Drink up!
