Disadvantages of Drinking Lemon Water Daily

Drinking lemon water in moderation is good, but it can cause many health issues in excess. Here are ten disadvantages of drinking lemon water daily:

1. Tooth Decay

Lemon has a high amount of acids. As per a study, excess lemon water can cause the dissolution of enamel or the outer layer of the teeth, leading to the removal of minerals. As per American Dental Association, teeth erosion makes teeth susceptible to decay over a period. It can also lead to sensitivity and pain. As per a study, lemon juice can have the same erosive effect on teeth as that of cold drinks.

You can use a straw to reduce direct exposure of acid present in lemon water with teeth. You should also avoid brushing your teeth just after having lemon water. Instead, try drinking lots of plain water along with lemon water. It will reduce the chances of having sensitivity.

2. Upset Stomach and Ulcers

If taken daily and in high quantities, it can cause damage to the stomach. Because of the acidity, it can cause heartburn, nausea, and vomiting. The disadvantage of drinking lemon water daily is that it can trigger ulcers. The acidic content of lemon can harm the inner linings of the stomach and intestine, leading to ulcers. If you are already vulnerable to it, avoid taking lemon water daily.

3. GERD and Acid Reflux

As per a study, acidic food can cause gastroesophageal reflux (GERD) and acid reflux. It occurs because the acid in lemon irritates the inner linings of the food pipe. It worsens when you drink lemon water on an empty stomach, and people who are prone to acid reflux should avoid drinking lemon water daily. The regurgitation of food in acid reflux can cause difficulty in swelling, worse asthma, cough, sour taste in the mouth and also, if it happens at night, it affects sleep.

4. Frequent Urination and Dehydration

As per studies, lemon water is rich in ascorbic acid or Vitamin C. It is diuretic in nature, which can lead to more urine production in the kidneys. Along with water, frequent urination will flush out electrolytes from the body. It can lead to dehydration, tiredness, dry lips, and excess thirst.

Also, the acidic content of lemon can irritate the bladder causing more urge to urinate. In this case, try balancing lemon water intake with the advice of a consulting physician.

5. Cause or Worse Canker Sores

Canker sores are ulcers inside the mouth, usually under the tongue or inside of the cheeks. As per a study, they are caused by acidic or spicy food, vitamin deficiency, or wearing braces. As per American Dental Association, over-consumption of lemon water can worsen the existing canker sores.

It can make eating and talking uncomfortable. If you find canker sores after consuming lemon water, you should stop consuming them.

6. Trigger Migraine

The disadvantage of drinking lemon water daily includes migraines and headaches. As per a study, citrus fruits like lemon can trigger headaches and migraines. Lemon and citrus fruits are high in tyramine. As per a study, tyramine is linked to migraines and headaches. So people who have long-term migraine can get frequent migraine attacks because of lemon water daily.

7. Risk of Cancer

Citrus fruits like lemon have psoralens. They are carcinogenic and can cause cancers. As per a study, increased consumption of lemon water (psoralens) can lead to an increased risk of skin cancer like melanoma. In this, different sizes and shades of mole appear on the skin. They can even ooze blood but are painless. If you notice such symptoms, consult a doctor.

8. Adverse Effect on Bones

Some researchers claim that lemon water is linked with bone health. Lemon can reduce the lubricants present in between the joints and bones over time.

9. Excess Iron

Any mineral that exceeds more than the normal level in our body is harmful. A normal iron level is important for energy production, haemoglobin formation and the function of certain enzymes in the body. As per a study, the vitamin C present in lemon water can increase iron absorption.

It can be beneficial for people with low Iron levels but can also lead to hemochromatosis. It is an excess storage of iron in the body that can damage organs over a period. It can also lead to weakness, fatigue, high sugar level, and skin pigmentation.

10. Trigger Sunburn

Lemon and other citrus fruits have psoralens. It is a chemical compound that can make skin sensitive to UV-A rays. The increase in the light sensitivity of the skin can cause excessive sunburn. It can worsen sunburn and cause phytophotodermatitis. It is a type of skin inflammation because of certain plant-based chemicals that occur when exposed to sun rays. It can lead to

  • Redness
  • Pain
  • Itching
  • Pigmentation
  • Blisters
  • Burning sensation


If you drink a hot or normal glass of lemon water daily in the morning or before bedtime, you don’t have to worry. It is beneficial if taken in moderate quantities. You can even add honey or ginger in lemon water to soothe an upset stomach. However, it can do more harm than good when you overconsume lemon water. The disadvantages of drinking lemon water daily include tooth decay, upset stomach, acid reflux, migraine, and increased risk of cancer.

If you observe any adverse side effects of lemon water on your body, reduce the quantity of lemon water or stop taking it. Consult a doctor to seek advice regarding lemon water intake.
