Top gastroenterologist reveals 8 things we probably didn't know about consuming lemon water

When a glass of lemon water is placed on the table, most people see it as a simple drink with a refreshing taste. But as Dr Saurabh Sethi, a leading gastroenterologist, points out, there’s more science behind it than meets the eye. Lemon water is often celebrated as a health elixir, yet not every popular claim about it holds true. Here are 8 lesser-known insights that can help in understanding this everyday habit better.

Plain water keeps the body hydrated, but for many, adding lemon makes it more enjoyable. Dr Sethi highlights that this small twist encourages consistent water intake, which is vital for every cell in the body. Sometimes, the appeal of a little citrus flavour is all it takes to keep hydration on track.

Lemons are packed with vitamin C, an antioxidant that supports immune function and skin health. According to Dr Sethi, while one glass of lemon water won’t meet the daily requirement, it certainly adds a gentle boost. It is like a microdose of nutrition slipped into the morning routine.

Not everyone knows that some people actually suffer from too little stomach acid. For them, the natural acidity of lemon can sometimes support better digestion. Dr Sethi notes that in such cases, lemon water might help kick-start the digestive process. However, it’s not a universal fix and should be understood in context.

Many assume hot lemon water is the healthiest version, but excessive heat can damage the vitamin C content. Dr Sethi suggests warm water is ideal, hot enough to feel soothing but not boiling. This way, the drink retains its natural benefits.

Citrus fruits are acidic, which means lemon water is not always gentle on everyone’s digestive system. Those with acid reflux may notice discomfort after drinking it. Dr Sethi emphasizes being mindful of body signals instead of blindly following trends.

Regular contact with lemon’s acidity can erode enamel over time. This doesn’t mean lemon water has to be avoided, but sipping it with a straw or rinsing with plain water afterwards can reduce the risk. Dr Sethi reminds us that oral health should be part of the wellness conversation too.

Perhaps the biggest myth is that lemon water “detoxes” the body. Dr Sethi is clear: the liver and kidneys are already doing the detoxification perfectly well. Lemon water may support hydration and digestion, but it doesn’t cleanse the system in any magical way.

Despite the myths, Dr Sethi views lemon water as a positive ritual. Starting the day with a glass can create a mindful moment that signals the body it’s time to wake up and function. In that sense, it can be a gut-friendly habit that brings balance without overpromising.
