6 Side Effects of Drinking Too Much Lemon Water

Lemon Water

Can too much lemon water be harmful?

Lemon water is healthy for you, but drinking too much of it can cause problems.

As the say goes, too much of a good thing can be bad for you.

The same is true for drinking lemon water.

It can have side effects that are not healthy, especially if drunk in large quantities on a daily basis over a long period of time.

The good news is that the side effects are not all negative.

There are several positives of drinking a glass of lemon water every morning, which is why it has become so popular.  

However, too much of a good thing can come with some negatives.

Here are 6 possible side effects of drinking lemon water

1. Damage your tooth enamel

Lemon juice is highly acidic and can damage your tooth enamel.

According to the American Dental Association, frequent exposures to acidic foods such as lemon juice can wear down tooth enamel over time.

And this can lead to potentially serious, long-term dental problems such as tooth decay and cavities.

To prevent this from happening, don’t brush your teeth immediately after drinking lemon water.

Give your saliva a chance to neutralize the acidity first.

In addition, you should drink plenty of plain water or rinse out your mouth with it.

2. Cause dehydration

When you drink a lot of lemon water, your body loses more fluids than normal.

This is because citric acid found in lemons has diuretic properties.

Therefore, it increases the frequency of urination and causes dehydration.

In addition, you lose electrolytes when you urinate frequently.

Electrolytes are minerals in your body that have key roles in the proper functioning of your heart, muscles, nerves, and digestive system.

If you become dehydrated, you may experience symptoms such as feeling thirsty, dry mouth, and dark yellow pee.

It’s important to drink water throughout the day to make up for what you lose in urine through lemon water consumption.

3. Lead to heartburn

Anyone who has ever experienced heartburn knows how unpleasant it can be.

Although you can drink water to help ease heartburn, drinking too much lemon water will actually make the condition worse.

Lemon juice stimulates excess production of stomach acid.

This can cause painful inflammation of your esophagus and irritate existing heartburn symptoms.

4. Trigger GERD symptoms

Drinking too much lemon water can also cause or worsen other digestive issues such as gastroesophageal reflux disease (GERD).

Typically, these symptoms include a burning sensation in your chest and a sour, acidic taste in the back of your throat.

Some sources say that lemon water can cause these symptoms because it stimulates the production of stomach acid and increases its production in the esophagus.

However, the National Institute of Diabetes and Digestive and Kidney Diseases recommended that if you have gastroesophageal reflux disease, you should reduce your intake of citrus fruits, including lemon juice.

The truth is if you have GERD or heartburn, you should limit your drinking of lemon water.

5. It can trigger migraines and headaches 

For some people, drinking too much lemon water can cause headaches or migraine symptoms.

This is because it contains tyramine, which is a natural chemical that can trigger migraine and headaches.

Bottom line?

If you get frequent migraines or headaches, consider avoiding drinking too much lemon water.

6. Cause diarrhea

There are no scientific studies that show that drinking too much lemon water can cause diarrhea.

However, some people claim that the high amount of vitamin C in lemons water can irritate your digestive tract and cause diarrhea.

Also, according to Business Insider, E. Coli was found in nearly 70% of the lemons, which can cause vomiting and diarrhea.

So, if you’re going to drink lemon water regularly, it’s a good idea to wash the lemons properly before squeezing them to minimize the risk of contamination.


Lemon water is healthy and can boost your immune system, but it can also cause certain side effects.

But that doesn’t mean you can’t drink it.

The key is to limit the amount you consume.

In addition, you should make sure to drink plenty of plain water throughout the day.

This way, you can avoid dehydration and other negative effects of drinking too much lemon water.
