Drinking Lemon Water Everyday in the Morning? Beware of 7 Side Effects Besides Numerous Benefits
Lemon water is healthy, but daily intake has side effects
Many of us believe that a glass of lemon water in the morning has many health benefits. Yes, it’s refreshing, rich in vitamin C, and often helps in weight loss and has metabolism benefits. But there is downside too! drinking lemon water every day, especially on an empty stomach, can sometimes do more harm than good.
Though it’s definitely healthy in moderation, too much lemon water has a few hidden side effects you might not know about. Let’s look at them one by one.
1. It can cause acidity and bloating
Because lemon juice is highly acidic, daily consumption can irritate the stomach lining. For people with gastritis, IBS, or acid reflux, it may cause heaviness, bloating, or discomfort.
2. Can Lead to Indigestion
Instead of helping digestion, too much acidity can disturb your stomach’s natural balance, sometimes leading to cramps, nausea, or even mild diarrhoea.
3. Erodes down tooth enamel
Citric acid is tough on your teeth. Over time, it can make them sensitive, discoloured, and suseptible to decay. Dentists suggest drinking lemon water through a straw and rinsing your mouth afterwards.
4. Can cause dehydration
Since lemon is a natural diuretic, it increases urination. Without enough plain water to balance it, you may feel dehydrated or face an electrolyte imbalance.
5. Might interfere with other medications
Research shows lemon juice can reduce the effectiveness of certain medicines, especially those for blood pressure, diabetes, and thyroid. If you’re on medication, it’s best to check with your doctor first.
6. Worsens heartburn and hyperacidity
For those prone to acid reflux, lemon water can make matters worse by increasing stomach acid, causing that familiar burning in the chest or throat.
7. Rare risk of allergies
Though uncommon, citrus allergies do exist. They can cause rashes, swelling, itching, or even breathing issues. If you notice such symptoms, stop immediately and consult a doctor.
So, should you stop drinking lemon water?
Not at all. Lemon water can still be a healthy, refreshing drink. It’s all about how and when you have it. A few tips to make it safer:
- Don’t drink it first thing in the morning; have it after meals instead.
- Always dilute it well.
- Use a straw to protect your teeth.
- Rinse your mouth after drinking.
- Limit it to 2–3 times a week.
Clearly, lemon water isn’t the enemy. The problem starts when it becomes a daily habit on an empty stomach. If you enjoy it in moderation, it can continue to be your refreshing, vitamin-rich drink without turning into a hidden health hazard.
