While drinking water with lemon is generally safe for most people, there are some potential side effects to be aware of. The acidity of lemon water can sometimes irritate the stomach lining, especially for individuals with acid reflux or ulcers.

Additionally, lemon water can also erode tooth enamel over time if consumed in excess. To minimize these risks, it’s important to drink lemon water in moderation and consider using a straw to protect your teeth.
